Here are some common camera parameters and their key points: ** 1. Basic parameters ** 1. ** Aperture ** - Usually, the lens would have an aperture value, such as f/1.8, f/2.8, etc. The smaller the number, the larger the aperture. For example, f/1.8 was a large aperture. A large aperture could increase the amount of light entering, affecting the depth of field (a large aperture would have a shallow depth of field and a strong background blurring effect), and it would also affect the shape of the stars at night (a small aperture would have obvious stars). 2. ** Focus ** - There would be a numerical indicator of the focal length on the lens. For example, for a 18 - 55mm zoom lens, the 18mm end was the wide-angle end. The focal length was small and could accommodate more objects, which was suitable for shooting scenery. The 55mm end had a relatively large focal length and could shoot objects from a longer distance. It was often used for portraits or close-ups. 3. ** Shutter Speed ** - The camera's shutter speed setting would be displayed on the camera's display or viewfinder. For example, 1/500s, 1/30s, and so on. A very fast shutter speed (such as 1/1000s or above) could freeze moving objects, and a slow shutter speed (such as 1/30s or below) could capture special effects such as water fog. 4. ** Light sensitivity (USB)** - You can view and set the value in the camera's menu or operation interface. The lower the USB, the clearer the picture would be, and the less noise there would be. In the case of sufficient light, a lower USB value is generally set, such as USB 100 - 400; in the case of dim light and stable equipment such as a tripod cannot be used, the USB value may need to be increased, but this will increase noise. 5. ** White Balance ** - The camera's white balance setting can be seen in the menu. The most common one was AWB, which was enough for daily shooting. You can also manually set the K value or select the default white balance mode, such as cloudy, sunny, tungsten light, etc., to obtain the correct color or achieve a special color rendering effect. 6. ** Picture format, size, and quality ** - The photo format (such as RAW or JPG), size (such as large, medium, and small), and quality (high, medium, and low quality) were also set in the camera menu. If you don't plan to retouch the photos later, you can choose JPG format. For daily shooting, it is recommended to adjust the size to large size and the quality to high quality. However, in the case of shooting news and other situations that require fast production, you may need to adjust it to medium or small size. 7. ** Metering Mode ** - The camera's light measurement mode (such as evaluation, spot, spot, center-emphasized, etc.) can be viewed in the camera menu or the operation interface. Metering was commonly used and could be used in most shooting scenes. In special cases, such as shooting backlit portraits, spot photography might be needed to accurately control the exposure. 8. ** Focus Mode ** - Most cameras had autofocus modes, such as AF-S (single autofocus, suitable for shooting still objects), AF-C (continuous autofocus, suitable for shooting moving objects), etc. You can view and switch the focus mode in the camera menu or through a specific button. 9. ** Compensation for exposure ** - In aperture priority or shutter priority mode, the exposure compensation value could be viewed and adjusted in the camera operation interface. Generally, setting it at 0EV could satisfy most scenes, but according to the principle of "white plus black minus", exposure compensation may need to be increased when shooting pictures with more white subjects, and exposure compensation may need to be reduced when shooting pictures with more black subjects. 10. ** Image confirmation ** - In the camera menu, you can set the image confirmation time. For example, you can set the photo to stay on the camera display for 2 seconds after shooting, so that you can check the effect of the photo. 11. ** Lens Aberration correction ** - Check the settings for lens aberrations correction in the camera menu, including peripheral brightness correction (turn it on to reduce dark corners), distortion correction (turn it on to reduce image distortion), digital lens optimization (you can choose standard modes), and so on. 12. ** High noise reduction setting ** - Check and set the high IQ noise reduction in the camera menu. In extremely dark environments, when lights, tripods, and extended exposure time were not allowed, high Iso-noise reduction could be set to reduce noise. Read more exciting novels for free
There were many parameters for the camera lens. The following were some common parameters: 1. ** Focus **: It determines the degree of zooming of the lens. A longer focal length was used for long-distance shooting. For example, a telephoto lens could be used to shoot long-distance topics such as sports competitions, wild animals, aircraft, etc., and it could also enhance the background blurring effect. A shorter focal length was used for wide-angle shooting, such as wide-angle lenses for landscape photography, architectural photography, and crowded indoor spaces. 2. ** Aperture **: For example, the main camera of the Vivo X200 Pro is equipped with a large aperture of f/1.57, which helps to take brighter and clearer photos in dark environments. Its periscope telephoto lens has an aperture of f/2.67, which can ensure the clarity and details of the picture when shooting telephoto. The size of the aperture affected the amount of light entering, depth of field, and so on. 3. ** Pieces **: It is one of the important indicators to measure the quality of the camera. For example, the main camera of the Vivo X200 Pro is expected to use a 50-million-pel large sensor, and the periscope telephoto lens is equipped with a 200-million-pel periscope telephoto lens. 4. ** Photosensor **: For example, the sensor of the HD - 3000 camera is a LCD; the main camera of the Vivo X200 Pro has a 1/1.28-inch sensor, and the periscope telephoto lens has a 1/1.4-inch base. 5. ** View angle **: For example, the helmet camera lens is a 3.7mm pinhole lens with a 90-degree view angle. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The main parameters of the camera lens were as follows: - Aperture: controls the amount of light that enters the lens. The smaller the aperture, the greater the amount of light that enters the lens, and the more obvious the background blurring effect. For example, in a dark environment, a large aperture could allow more light to enter the camera and take a bright photo. At the same time, it could highlight the subject and blur the background. - ** Focus **: determines the angle of view and magnifying power of the lens. The short focal length lens had a wide angle of view and was suitable for shooting large scenes such as landscapes. The long focal length lens had a narrow angle of view and could zoom in on distant objects. It was often used to shoot portraits, close-ups, or sports events that needed to be zoomed in. - ** Shutter Speed **: The length of time the shutter is opened. A fast shutter speed could freeze instantaneous movements, which was suitable for shooting moving objects, such as fast running athletes. A slow shutter speed could capture the trajectory of the object's movement, such as shooting a smooth effect when shooting water. However, a slow shutter speed needed to be used with a tripod to prevent blurring caused by hand shaking. - [Depth-of-field]: It refers to the range of clear images before and after the focal point. A large aperture would cause the depth of field to become shallow, that is, the clear range before and after the focus was small; a small aperture would cause the depth of field to be large, and the clear range before and after the focus would be wide. - ** Light sensitivity (USB)**: It indicates the sensitivity of the camera to light. The higher the value, the more sensitive the camera was to light. In a dim environment, the camera could increase the brightness by raising the value, but an overly high value would cause noise and affect the image quality. - ** White Balance **: Adjusts the camera to ensure that white objects appear white under different lighting conditions. Automatic white balance (AWB) for daily shooting can basically meet the needs, but it can be manually controlled in special scenes or when you want to change the image effect, such as using the built-in scene mode, manually adjusting the K value, etc. - ** Distortion **: Different types of lenses may have different degrees of distortion. For example, wide-angle lenses may produce barrel distortion, and telephoto lenses may produce pincushion-shaped distortion. This was something to take note of when shooting objects that required strict shapes such as buildings. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The following is an understanding of some common camera parameters: ** 1. Image quality-related parameters ** 1. ** Pieces ** - Pieces were the smallest unit that made up an image. For example, if the long side of a photo was 6000 pixelation and the wide side was 4000 pixelation, the photo would have 24 million pixelation. Usually, the higher the resolution, the clearer the image would be when magnified. However, the quality of the image was not entirely dependent on the resolution, but also on the size of the sensor. For photography, the resolution was an important consideration. Although some people thought that 20 million pixelation was enough, there were advantages to having a higher pixelation. Unless they often shot sports and dark environments, the high sensitivity of high-pixelation machines could not be considered for the time being. This was because some flagship machines sacrificed high pixelation for sports scenes in continuous shooting and high-sensitivity balance. 2. ** size of the sensor ** - There were different types of full-frame and half-frame sensors. The size of the sensor affected the image quality. For example, full-frame sensors might have certain advantages in terms of image quality. 3. ** Picture format ** - The main ones were the RAW format and JPG format. If you don't want to do post-processing, JPG format will do, but if you want post-editing, it's more suitable to choose the RAW format. 4. ** Picture Quality and size ** - For daily shooting, the size can be adjusted to large size and the image quality can be adjusted to high quality. However, when shooting news topics and other situations that required quick release, the photo size might have to be adjusted to M or S. 5. ** Picture Style ** - The camera had a variety of photo styles. It was recommended to choose the "standard" style for daily shooting unless there were special needs or you wanted to try other styles. ** 2. Exposure-related parameters ** 1. ** Aperture ** - The larger the aperture, the brighter the image. The aperture settings were different in different shooting scenes: - The aperture for landscape shots was usually F8 - F11. - When shooting portraits, you can use the maximum aperture or the maximum aperture can be reduced by one stop. - In cultural street photography, if you need to blur the environment, the aperture is F2.8 or larger. If you don't need to blur the environment, it is F8. - The aperture for macro shooting was F8 - F11. - The aperture range for shooting the starlight effect was F8 - F11. - When shooting flowers, birds, and insects, the aperture should be at F5.6 or below, and the best is to have an IQ of 400 or less. - The aperture also affected the depth of field. The larger the aperture, the shorter the depth of field. 2. ** Shutter ** - The slower the shutter, the brighter the image. There were different shutter speeds for different subjects: - The shutter speed needed to be above 1/60s to shoot general body movements. - Walk for more than 1/125s. - Faster than 1/500s. - Running for more than 1/1000s. - Skiing 1/2000s and above. 3. ** Light sensitivity (USB)** - The higher the sensitivity, the brighter the image. For daily shooting, you can set it to "STAR"(automatic sensitivity). When you use manual (M), you may manually adjust the sensitivity to control the image exposure. ** 3. Focus related parameters ** 1. ** Focus point ** - The more focal points a camera of the same brand had, the better. However, different brands had different focusing techniques, and the speed of focusing could not be compared by the number of focal points. 2. ** Face recognition, eye focus ** - It could focus on a person's face, eyes, and even animal eyes. Many new models had this function. ** 4. Other parameters ** 1. ** White Balance ** - Automatic White Balance (AWB) for daily shooting basically meets the requirements. Manual control is required for special scenes or when you want to change the image effect, such as through the built-in scene mode, manual adjustment of K value, etc. 2. ** Metering Mode ** - This included evaluation photography (Nikon Matrix Metering, Sony-called Multiple Metering), spot photography, partial photography, center-emphasized photography, etc. The most commonly used was evaluation photography, but in complex situations, spot photography, center-emphasized photography, etc. might be chosen. 3. ** Anti shake performance ** - The anti-shake function could reduce the probability of taking photos and making it easy to hold the picture when shooting videos. However, the body with anti-shake function was usually more expensive and needed to be chosen between budget and functional requirements. 4. ** Continuous Shooting Speed ** - If you often shoot sports, you need to pay attention to this parameters. Daily applications can basically be ignored. 5. ** Highest and extended IPs ** - If you are often involved in extreme subject matter shooting, you can consider this factor, but you don't have to consider it for daily use. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The camera shooting parameters included many aspects: 1. ** Picture format and quality **: - There were two types of photo format: RAW and JPG. If post-processing was not needed, the JPG format was fine, as it took up less memory. If post-editing was needed, the RAW format was more suitable, as it saved more original environmental colors, but most of the photos were gray and took up a lot of memory. 2. White Balance: - Automatic White Balance (AWB) could basically meet the needs of daily shooting and restore the true color of the environment. If you want to adjust the environment, you can also adjust the color temperature parameters later. In addition, the lower the white balance value, the colder the image, suitable for shooting night scenes, snow scenes, etc. The higher the value, the warmer the image, suitable for shooting sunrise, sunset, autumn, etc. 3. ** Light sensitivity (USB): - For daily shooting, the sensitivity could be adjusted to "STAR"(Automatic sensitivity). Now the camera had better high-sensitivity and the image quality was less affected. However, it could also be manually adjusted to 100, unless the three elements of exposure needed to be adjusted to a higher IQ or the quality of the photo was not high. When shooting in low-light areas at night without a flash, it was generally necessary to increase the IQ. 4. ** Compensation for exposure **: - In Aperture priority/Shutter priority mode, the setting of "0EV" was generally sufficient for most scenes. In the automatic mode, aperture priority, and shutter priority modes, the exposure compensation was increased when the photo was dark, and decreased when the photo was bright. 5. ** Shooting Mode **: - There were mainly automatic mode, automatic program mode, P-mode, aperture priority, shutter priority, manual exposure, and other modes. 6. ** Metering **: - Most of the time, you can choose to evaluate the light measurement (matrix light measurement, average light measurement). It can measure the entire shooting scene to meet the needs of most scenes. There were also center-focused average dimming (the dimming area was about 1/3 of the middle of the screen) and spot dimming (about 3% - 5% of the screen) to choose from. 7. Focus: - Commonly used focusing modes were single-point autofocus AF-S (suitable for shooting still objects, etc., half press the shutter to focus once), servo-autofocus AF-C (suitable for capturing moving subjects, half press the shutter to maintain tracking focus), smart autofocus AF-A (automatically select AF-S or AF-C, according to the subject's movement or stillness), and manual focus (manually adjust the focus ring, use when autofocus is not available or when there is an error). 8. ** Picture Style **: - There were many settings such as auto, standard, portrait, and landscape. It was recommended for beginners to choose the standard style first, and then choose or set other styles after familiarizing themselves with photography and camera usage. 9. ** Different shooting scene parameters **: - ** Scene (M-file)**: On a sunny day, around 100, F8, 1/200. On a cloudy day, around 400. - ** Aperture priority mode (LV)**: - Scenery photos taken in the light: F8 - F11, exposure compensation 0. - When shooting a portrait, the maximum aperture or the maximum aperture was reduced by one stop, and the exposure compensation was 0. - Street photography: F2.8 or higher (requires virtual environment)-F8 (does not require virtual environment). - For macro photography, F8 - F11. - [Starlight effects: F8 - F11] - For shooting flowers, birds, and insects, the aperture should be at F5.6 or below, and the best was to have an IQ of 400 or less. - ** Shutter priority mode (TV)**: - General body movements: 1/60s or above. - Walking time: 1/125s or more. - [Fast travel: 1/500s and above.] - Running: 1/1000s or above. - Skiing: 1/2000s and above. - [Bike: 1/2000s and above.] - Normal speed of the car: 1/2000s or above. - [Flight distance: 1/500s] - Follow-up photography: 1/60s- 1/4s - [Freezing birds nearby: 1/4000s] - [Fog Sea: 1/4s or slower] - ** Manual Mode (M)**: - Full Moon: 1/500s, Isotta:200, F5.6 - F8(Clear). - Crescent Moon: 1/500s, USB:200, F4 - F5.6(Clear). - [New Moon: 1/500s, USB:400, F4] - Firework: 1s- 4s, USB:200, F8. - [Lightning: B-door, USB:200, F8 (until the end of the shot, the environment should be darker).] - Street light line: 15s, USB:100, F11 (adjusted according to street brightness). - Water surface boat light line: 30s, USB:100, F8 (adjusted according to environmental brightness). - Galaxy: 30s, USB:1600 - 6400, F2.8 (with super wide angle). - Star Orbit Shooting: Each photo was exposed for 30 seconds, and the next photo was taken at an interval of 1 second. At least 120 photos were taken and stacked later. - Flower Shooting: 1/125s, F2.8, USB:100(sunny weather). - Scenery: 1/125s, F4, USB:100(sunny). - Night scene: 1/15s, F1.8, and 200. - Ripping motion: 1/500s, F2.4, USB:100. - Wedding room: 1/125s, F2.8 - F8, Isotta:400. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The following are some examples of camera parameters for Japanese style photography: - ** Rainy day series **: White balance is 5600K, white balance offset is B4M4, photo style is neutral mode, detailed style parameters are: Strength +4, Fineness +1, Critical Value +1, contrast-4, saturation-2, hue 0. - ** Japanese Fresh **: White balance is K5200, white balance offset is B2, M2, photo style is portrait mode, detailed settings are: intensity 3, precision 4, critical value 4, contrast-3, saturation +1, hue +2. - ** Warm Japanese TV Series **: White balance set to K4800, white balance offset set to B1, G2, photo style set to neutral mode, detailed settings set to intensity 2, precision 3, threshold 1, contrast-4, saturation-2, hue 0. However, in actual shooting, it still needed to be adjusted according to the specific shooting environment, shooting equipment, personal creativity, and other factors. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Different types of blockbusters (such as movies, landscape blockbusters, portrait blockbusters, etc.) required different camera parameters. The following are some common settings: - ** Picture format, size, and quality **: If you don't need post-editing, you can choose JPG format; if you want post-editing, the RAW format is more suitable. For daily shooting, the size could be adjusted to large size and the picture quality could be adjusted to high quality. However, for shooting news topics, the photo size might need to be adjusted to M or S. - ** White Balance **: Automatic White Balance (AWB) can basically meet the needs of daily shooting. In special scenes or when you want to change the image effect, you can use the built-in scene mode, manually adjust the K value, etc. - ** Light sensitivity (USB)**: For daily shooting, you can set it to the "STAR"(Automatic Light sensitivity). When you use the manual (M), you can manually adjust the light sensitivity to control the image exposure. - ** Picture Style **: The camera has a variety of photo styles. It is recommended to choose the "standard" style for daily shooting unless you have special needs or want to try other styles. - ** Metering Mode **: The most commonly used is evaluation measurement (Nikon Matrix Metering, Sony-called Multi-Metering), which can satisfy most shooting. In complex situations, spot measurement, center-emphasized measurement, etc. may be selected. - ** Focus Mode **: For daily shooting, choose AF-S + single-point autofocus; for shooting moving objects, choose AF-C + extended focus. - ** exposure compensation **: In aperture priority/shutter priority mode, it is usually set to "0EV", which can satisfy most scenes. At the same time, the exposure compensation must be adjusted according to the "white plus black minus" rule. For the Hong Kong Style night scene blockbuster camera, the settings were as follows: the sensitivity was pulled to above 3200 to obtain a high graininess, the aperture was used to 5.6, and the speed was switched between 80 and 100. If the camera could not adjust the K value, it could directly use the white fluorescent light mode (4000K). Combined with the Canon camera's landscape mode, the sharpness was pulled to the full, the contrast was increased by two gears, the saturation was increased by two gears, and the color tone was pulled to the right to the top. Different blockbuster styles also needed to be adjusted and optimized according to the actual shooting environment and the subject. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The optical parameters of the camera included the following aspects: 1. ** focal length **: This is a very important optical parameters of the lens. It refers to the distance from the main point of the lens to the focal point. It is an important performance indicator of the lens. The length of the focal length of the lens was inverse to the size of the image taken by the lens. That is, under the same object distance, the larger the focal length of the lens, the smaller the size of the image taken. Most industrial cameras use fixed-focus lenses in practical applications. Before choosing the focal length of the lens, you need to know the object distance of the on-site camera (the installation height of the camera lens from the surface of the measured object) and the field of view of the camera (the size of the characteristics of the measured object). In some applications involving the mixed inspection of objects at different heights, the use of a variable focal length lens would be considered. However, the variable focal length lens had two issues to consider: zooming speed and lens life. 2. ** Depth-of-field **: When the focal length of the lens is adjusted to a focal point, only the objects within a certain distance before and after the focal point are clearly visible. The objects outside this distance are blurred. This distance is the depth of field of the lens. 3. ** Pieces and resolution **: Pieces are the smallest unit of an image generated by the imaging chip, such as a 2-million-pel image. The resolution referred to the imaging ability of the CCD-or CMOS-chip. For example, the resolution of a 2-million-pel camera was 1626 x 1236, which meant that the camera had 1626 x 1236 rows in the X-axis direction. The total image taken was about 2 million pel. The detection accuracy could be simply evaluated by dividing the actual size of the image's X-axis by the number of X-axis dots. However, the final detection accuracy was affected by many factors, including the moving speed of the object being measured, light interference, the shape of the object, the contrast of the features, the computing power of the software, and so on. 4. ** Picture element size **: This is also an important optical parameters of the camera. 5. ** Target size of sensor **: It is the most concerned part of the camera's optical parameters. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The camera panel parameters include many aspects. The following is a detailed introduction: ** 1. Setting of parameters related to focusing ** 1. **AF - ON** - It can be set to switch between single focus, autofocus, and servo-autofocus. When setting up, click the AF-ON button, then click the menu button. In the pop-up menu, select the second camera setting from the right in the first layer of the menu. Choose 3 in the second layer of the menu (that is, select the custom button), find AF-ON and set it as the autofocus start button. This way, you can directly use AF-ON to select the focus mode when taking pictures. 2. **M - FN** - It can be set to drive mode, focus mode, white balance, light measurement mode, etc. Find the custom button in the MENU settings, click M-mn, and set it according to the content ticked in the detailed information. During the shooting process, click M-mn to change the setting content at will. ** 2. The parameters related to the shooting effect previews ** 1. ** Depth of field button ** - It could be set to a photo style. In the MENU, follow the specific setting steps (similar to finding the custom button when setting AF-ON), select the depth of field in the custom option. After setting it to the photo style, you can use the depth of field button to choose portrait shooting or landscape shooting. ** 3. The parameters related to the imaging display ** 1. ** Image confirmation ** - It was mainly used to display the photo on the camera for a short time after shooting to check the effect of the film. In the first camera setting on the first layer of the MENU button, there was an image confirmation option under the seventh menu on the second layer. Generally, you could choose the image confirmation time of 2 seconds. ** 4. Photosensitivity related parameters ** 1. ** Light sensitivity (USB)** - You can set the minimum and maximum value. After setting it, you can adjust the sensitivity within this range. The best image that the equipment could bear was the maximum value. If the value exceeded this value, the noise in the photos would increase. The setting step was to set up the camera on the first layer of the MENU setting, click on the 2 option, and then enter the sensitivity setting menu and select the automatic range. The maximum and minimum values were set according to the equipment's tolerance range. 2. ** High noise reduction setting ** - In extremely dark environments, when there were no lights or tripods, and the exposure time could not be extended, a high IQ noise reduction could be set to adjust the brightness of the picture, but this was not a long-term solution. It was best to add lighting equipment when the environment was not bright enough. In the MENU settings, the first camera setting on the left, click on the high iso sensitivity noise reduction function in option 4, and you can choose strong. ** 5. The parameters related to lens correction ** 1. ** Lens Aberration correction ** - Turn on the peripheral light correction to reduce dark corners, turn on the distortion correction, and select the standard for digital lens optimization. The setting step was to set the camera settings on the left side of the first layer of the MENU settings. Then, click the lens phase difference correction in the option 3, set the surrounding light correction to-on, the distortion correction to- on, and the digital lens optimization to-standard. ** 6. Shutter-related parameters ** 1. ** Memory card not installed, release shutter ** - If he didn't choose to close it, he could press the shutter without a memory card, and if he chose to close it, he couldn't press the shutter without a memory card. In the MENU settings, the first camera setting on the left of the first layer, click on the uninstalled memory card in option 6 to release the shutter. It is recommended to choose off. ** 7. Attributes related to composition assistance ** 1. ** Gridline Setting ** - Regardless of whether you are a novice or a veteran, the grid line can be used as a reference line for composition. It is recommended to keep it on. In the MENU settings, the first layer was the left camera setting. In option 7, click on the shooting information display-show grid line-3x3 grid line, so that the "Jing" line would appear on the camera display. In addition, the camera parameters also involved white balance (such as a specific K value and white balance offset), photo style (including the settings of parameters such as intensity, precision, threshold, contrast, saturation, and hue), etc. Different settings of these parameters would affect the color, style, and other effects of the photo. At the same time, different models of cameras might have different settings for the panel parameters. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The following are some of the main parameters of the camera: ##1. Calculation of the camera's resolution The camera's resolution = horizontal resolution * vertical resolution. ##2. Chip size Calculation Chip size = horizontal size * horizontal resolution. The size of the sensor chip = the resolution * the size of the picture element. ##3. Calculation of resolution resolution (Pixel1) = camera field of view (mm) /resolution (mm /Pixel1). The unit size (width)= sensor size (width)/resolution (width), and the unit size (height)= sensor size (height)/resolution (height). ##4. Precise Calculation The precision referred to the size of the actual object in one pel, which was expressed as (um*um)/pel. The size of a single picture element = width of field of view/width resolution = height of field of view/height resolution. "Picture accuracy = picture size/lens magnification;""Picture accuracy = camera field of view/camera resolution." The size of the short side of the product/the number of short side of the selected camera. ##5. D/d calculation (for calculations related to focal length) Find an object with a known length (just a standard plate) and take a picture of its length in the camera image when it is in focus (for more accuracy, make the length of the object and the length of the image as parallel as possible). Then D/d = the actual length of the object/(length of the image * size of the image). Pay attention to the unit between the size of the image and the actual length. ##6. Calculation of lens magnification The lens magnification was equal to the chip size/the actual field of view required. In terms of frame rate, for an area array camera, the frame rate (fps frame rate) represents the number of pictures that can be taken per second; the line frequency (16 kilosecond line frequency) corresponds to a line array camera, which represents the number of lines that can be scanned per second. The maximum image resolution is resolution * line frequency (example, 2048 x 16k). These parameters reflected the maximum efficiency of the camera, and together with the exposure, they determined the brightness of the image (if the frame rate and line frequency were high and the exposure was low, the image would be very dark; if the frame rate and line frequency were low and the exposure was high, the image would be very bright). The size of the image element refers to the actual physical size of each image element on the chip's image element array. The size of the image element and the number of image elements (resolution) together determine the size of the camera's target surface. Usually, the size of the image element of an industrial camera is 2 pm- 14 pm. The size of the image element reflects the light response ability of the chip to a certain extent. The larger the image element size, the more number of photons it can receive. The more charges it can generate under the same lighting conditions and exposure time. The size of a picture element was a representation of the chip's sensitivity. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The camera recording parameters mainly included the following aspects: 1. ** Video format **: There are two types of video, namely, feast and PAL. China (Europe)'s television industry standard was PDA, while the United States (Japan, South Korea, and other countries)'s television industry standard was NSA. The video frame rate that could be selected was 25 frames per second (50 frames, 100 frames) in the PDA format, and 30 frames per second (60 frames, 120 frames) in the NSA format. It was recommended to choose the Polar format for filming in China to avoid the phenomenon of light strobing. 2. ** resolution **: It refers to the number of the number of the displayed image in each picture. It is usually expressed by the product of the number of horizontal and vertical images (for example, 1920X1080) or the number of vertical images (for example, directly marked as 1080). The higher the value, the finer the image and the better the quality. 3. ** frame rate **: For example, 1080P 60fps, 1080P 30fps, etc., often appear together with the resolution. 4. ** Bitrate (Bitrate)**: This is also a setting that needs to be selected before shooting a video. 5. [** USB (Light Speed)**: Can be adjusted in professional video mode or movie mode. When the USB is low (e.g. around 100), the picture will be more delicate, with less noise and higher contrast. However, high sensitivity will easily produce noise. After determining the shutter and aperture, the USB is mainly used to coordinate the light in the picture.] 6. ** Shutter Speed **: Normally, the shutter speed is twice the number of frames. For example, if the video format has a frame rate of 25 frames, the shutter speed can be set to 50. If the shutter speed is lower than this value, the video will have a serious smear effect. If the shutter speed is higher than this value, the image will be clearer. 7. ** Aperture **: The aperture size affects the depth of field effect of the picture. The smaller the aperture, the larger the value, and the deeper the depth of field. The larger the aperture, the smaller the value, and the lighter the depth of field. For example, F5.6 was easy to shoot with a shallow depth of field (the subject was clear and the background was blurry), while F16 had a deeper depth of field. 8. ** Recording format **: If there are no special requirements, you can choose to record a 1920*1080 25 frame MOV format HD video. If there are special requirements for zooming in, you can choose 4K or other format. In addition, when shooting with multiple cameras, it was recommended to set up a unified video recording format to reduce the trouble in the later stages. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
