Picture and video resolution
Different devices had different camera and camera resolution. ** 1. Mobile phone ** The Gionee A286 was launched in April 2008. Its screen resolution was 240×320pix and it had a built-in 300,000 CPU camera. However, this could only be used as an example of an early mobile phone. It did not clearly indicate the resolution of the photos taken. Modern cell phones with high resolution usually took better pictures with more details, but there was no specific resolution value mentioned. In terms of photo multiplication, there were some techniques such as using 2x for the half body to make the facial lines smooth, 1.5x for the big body to make the person and the scene one, and 0.8x for the whole body to make the long legs go against the natural order. However, this was not directly related to the resolution. ** 2. Digital camera ** The resolution of a typical digital camera was 640×480 and 320×240. In recent years, more and more digital cameras supported high-definition video recording. In addition to the first two, they also supported high-definition video recording at a 1280×720 frame rate of 30 frames per second. ** 3. Regarding the principle of camera resolution ** From a more theoretical point of view, when the original high-resolution image was reduced to a lower resolution, it might have a higher sharpness than the original low-resolution image. This was because during the process of storing the code, the image would be "sample" due to factors such as the transmission speed, causing the sharing of information between the elements, resulting in a loss of color information. When the high-resolution image was down-converted, the low-resolution image's pixel-based image could obtain more complete and independent brightness and hue information from the high-resolution image's pixel-based image, thereby improving the quality and sharpness. For example, the sharpness of 4K in the original shot and the 6K to 4K in the post-production was not as good as the latter. The same was true for 1080p in the original shot and 4K to 1080p in the post-production. The common sample methods were 4:2:0 (every 4-pixelated group, only the first one has color value information, the other three borrow color), 4:2:2 (every 4-pixelated two have independent color information), etc. 4:2:0 was the mainstream sample method for consumer-grade cameras or cameras at this stage. Higher-end cameras had 4:2:2 options, while professional video recording format used at least 4:2:2 samples. If the 4:4:4 sample or RAW level could be achieved, the sample loss could be avoided, but such equipment was expensive. Read more exciting novels for free

Fisheye lens video post-correction
The post-production correction of the fisheye lens video mainly involved the following steps: 1. Extracting the camera's calibration-parameters: First, the camera's calibration-parameters must be obtained, including the lens 'distortion model and the camera's internal and external parameters. These parameters can describe the optical characteristics of the fish-eye lens and the camera's imaging geometry. 2. Distortion correction: Use the camera's correction parameters to correct the distortion in the image. This can be achieved by re-projecting each and every one of the elements so that the lines and shapes of the image are more straight and natural. 3. Perspective transformation: The image after fisheye correction usually becomes a circle or hemisphere, so perspective transformation is needed to restore it to a standard rectangular or square shape. This can be achieved by adjusting the projection method of the image. 4. [Image Cropping: After perspective transformation, there will often be distortions or black edges. At this time, image trimming can remove invalid areas and edges to ensure that the image is complete and without distortion.] Through the above steps, the video captured by the fisheye lens can be converted into a video closer to the standard perspective, reducing or eliminating the video distortion effect caused by the fisheye lens. However, it should be noted that correction may affect the image quality. For example, the edge image quality of the fisheye lens may be further improved after correction, but the center image quality is usually not affected, and the angle of view will change after correction. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
