Canon announces patents for full-pixel dual-core CMOS dynamic range enhancement technology
Recently, Canon announced the Pixel dual-core CMOS dynamic range enhancement technology patent, patent number 2019-129491. At present, each pixel of a full-pixel dual-core CMOS image sensor is equipped with two photodiodes, so that it can capture two image signals with different phases, and have both focusing and imaging functions. But from the perspective of the exposure patent, a single pixel will output two gain signals at the same time, and the dynamic range of the entire sensor can be improved by processing the two signals in combination.

I believe that in the next year or two, Canon, Nikon, Sigma, etc. will basically launch high-pixel full-frame mirrorless cameras, but it can be said that the Sony A7R4 camera is more like a benchmark for full-frame mirrorless cameras with high pixels. Let’s follow DPReview to…
