Nowadays, the improvement of smartphone image effects highly depends on the technological innovation and upgrade of CMOS image sensors. Even if it can leverage the later algorithms to save a large amount of optical information of the original image to the maximum extent, it is of great benefit to enhance the tolerance of post-processing. The current 3 major upgrade directions for CMOS images are high pixels, high frame rate and high imaging effects, covering many technical indicators such as pixel size, CIS size, number of pixels, architecture, quantum efficiency, sensitivity, etc. (Changjiang Securities report)
