Why not use ccd for red?

Red does not use ccd. The larger the area of photosensitive device, that is, the larger the area of CCD/CMOS, the more photons are captured, the better the photosensitive performance and the lower the signal-to-noise ratio.

It has better tolerance and color performance, and can use higher sensitivity. However, the processing cost is high, and the processing cost of power-consuming cmios is low, all of which are aimed at large-area photosensitive elements. The ccd and cmos in ordinary cameras are actually the same, and there is basically no difference.

Full format CCD:

This CCD has greater power handling capacity, better dynamic range, low noise and transmission optical resolution. Full-format CCD can take full-color pictures instantly. Full-format CCD consists of parallel floating-point register, serial floating-point register and signal output amplifier. Full-width CCD exposure is controlled by mechanical shutter or gate to save the image.

Parallel registers are used for metering and reading metering values. The image is projected onto a parallel array as a projection screen. This element receives image information and divides it into discrete quantization elements determined by numbers. These information flows will flow from parallel registers to serial registers. This process is repeated until all information is transmitted. Then, the system performs accurate image recognition.
