Apple on camera mode
Huawei Apple camera
Apple's mobile phone had always insisted on using a 12-million-pel camera until the iPhone 16 series had a certain upgrade. The ultra-wide-angle lens was upgraded to 48-million-pel, and the 16Pro supported 5x optical zoom. Huawei's cameras had different pixelation for different models. For example, the three quad-focal segments of the Huawei Pura70ultra all supported 25 million pixelation. Moreover, Huawei had an advantage over Apple in terms of resolution and zooming ability, especially in night scene shooting and long-distance shooting. However, in addition to the image quality, the camera's imaging effect was also affected by software algorithms, camera, sensor technology, and other factors. Apple also had a strong competitive edge in the mobile phone camera market by optimized the camera's exposure parameters, white balance, sharpness, and other effects. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

How to adjust the camera size of the Apple camera
If it was an iPhone camera, the default setting was to automatically adjust the photo size. However, you can adjust the size of the photo by setting it to a square or rectangular shape before taking the photo, or you can adjust it during editing. In addition, after shooting, you can also use third-party software (such as camera 360, beauty camera, etc.) to cut and trim. Some iPhone models can be found in the camera settings and click on the photo style and size or similar options. Usually, you will see several default resolution options, such as full size, high or medium quality. If you need more advanced customizations, you can go to Storage and Backups, where there are optimized iPhone storage options. By default, the image will be compressed to save space. Turn it off to retain the original resolution. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Computer for camera parameters
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>
