When judging the camera function of a mobile phone, people always intuitively believe that the higher the pixel of the mobile phone, the better the camera effect. Is this really the case. From the imaging principle, the size of the pixel value will have a certain influence on the generated image. When the image sensor area of the mobile phone is certain, the higher the pixel value, the smaller the unit pixel area. The unit pixel area directly affects the amount of light entering. The smaller the unit pixel area, the less light entering the image sensor, and the captured photos will become dark and blurry; the lower the pixel value, the larger the unit pixel photosensitive area and the better the photosensitive performance. Good
it has better performance in terms of high-sensitivity image quality and picture level of imaging.
