• abstract: A CMOS image sensor densely and uniformly placed the retinal rod- and cones-like WRGB pixels with lateral overflow integration capacitors having the different sizes in each color has been demonstrated. A 1/3.3-inch, 4.2-µm effective pitch, 1280H H 480V checker-pattern pixels CMOS image sensor was fabricated and has achieved color-independent saturation and about twice the effective sensitivity compared with conventional Bayer-RGB color filter image sensor made at the same time.
