Take the Olympus E-M5 as an example. It was the flagship of the M4/3 system. It was 122x89x43mm in size and weighed 425g. It was in the style of the OM series, a classic camera from the film era. In terms of sensors, it used a 16-million-pel sensor with a size of 17.3 × 13 mm. The sensor type was Live mos and it was equipped with an ultrasonic dust removal system. The image processor was TruePic VI. It had an effective resolution of 16.1 million, and the highest resolution was 4608 × 3456. There were autofocus methods, including single autofocus (S-AFs), continuous autofocus (C-AFs), manual focus (CHF), S-AFs + CHF, AFs tracking focus (C-AFs + CHF), and a focus assist light to assist in focusing. On the display function, there was a 3-inch, 610,000-pixel-rotating LCD screen with touch shutter, touch zoom, and other touch functions. The angle could be adjusted up by about 80 degrees and down by about 50 degrees. There was also the 1.44-million-pel EVF electronic viewfinder, which had a 100% field of view and a 0.92 - 1.15 magnification. It was equipped with a 1.44-million-pel EVF and a 5-axis image stabilization system, which could achieve up to down, left and right, and xy and z three-axis rotation shake correction. The anti-shake effect could reach-5ev, and it could shoot 1080p60 full HD video. There was also news that there might be an M43 format professional grade mirrorless camera flagship named OM-1, which would be equipped with a 24-million-pel LCD image sensor, but there was no more information about its detailed parameters.

The following are some of the more important parameters of the micro-camera: 1. * * Focus mode related parameters (such as AF-ON setting)**: It can be set to single-focus, autofocus, and servo-autofocus switching, which directly affects whether the focus can be fast and accurate during shooting. For example, servo-autofocus is critical when shooting dynamic objects, and single-focus may be enough for shooting static objects. A reasonable setting can improve shooting efficiency and quality. 2. * * Depth-of-field button settings (such as setting it to a photo style)**: It can be used to choose different styles such as portrait shooting or landscape shooting. This will affect the depth of field effect of the picture. A shallow depth of field may be needed to highlight the main character when shooting a portrait, and a large depth of field may be needed to ensure the clarity of the whole picture when shooting a landscape. 3. * * Image confirmation time **: The length of time the photo stays on the camera after shooting. If it is set to 2 seconds, the photographer can quickly check the effect of the photo so that he can adjust the shooting parameters in time. 4. * * Spectral sensitivity setting **: The setting of the minimum and maximum values limits the range of sensitivity adjustment. The maximum value is generally the best image effect that the device can bear. If the maximum value is exceeded, the noise in the photo will increase. The appropriate sensitivity setting can ensure that the photos taken under different lighting conditions are of good quality. 5. * * LensAberration correction parameters **: Including peripheral brightness correction, distortion correction, and digital lens optimization. For example, if peripheral brightness correction is turned on, it can reduce dark corners, and if distortion correction is turned on, it can avoid image distortion. 6. * * High Iso-noise reduction setting **: In extremely dark environments, when other means (such as lighting, tripod, and extended exposure time) cannot be used to adjust the brightness of the picture, this setting can improve the picture quality, but it is not a long-term solution. 7. * * Shutter release setting without a memory card installed **: If it is set to off, shooting accidents caused by accidentally pressing the shutter without a memory card installed can be avoided. 8. * * Gridline setting **: Although it is not a factor that affects the image itself, it is a reference line for composition. It is helpful for both novices and veterans. The importance of these parameters would vary according to different shooting needs and scenes. For example, the sensitivity and high noise reduction settings were particularly important in low-light environments, and the parameters related to the focus mode were even more critical when shooting moving objects. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The parameters of the Nikon 100 micro (Nikkor Z macro 105mm f/2.8VR S) lens are as follows: 1.

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 external parameters of the camera were parameters in the world coordinate system, mainly referring to the rotation and translation matrix between the camera systems, such as the position and rotation direction of the camera. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Some cameras can set the clock signal. For details, please consult the camera supplier. After determining the camera's PixelClock, when setting the PixelClock of the capture card, the PixelClock value of the capture card is required to be equal to the PixelClock value of the camera. Under normal circumstances, this value is the default value and does not need to be changed. <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>

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>
