摘要

光感测器具有光罩层及第一相邻光二极体，该光罩层具有在光二极体上面的开口，该第一相邻光二极体覆盖有光罩层，且位于足够靠近光二极体，使得至少一些通过光二极体上面的开口的光，能够经由光二极体而到达第一相邻光二极体。光感测器还具有第二相邻光二极体；该第二相邻光二极体覆盖有光罩层，且位于足够靠近第一相邻光二极体，使得至少一些通过光二极体上面的开口的光，能够经由第一相邻光二极体而到达第二相邻光二极体。电路系统被设置用来读取光二极体并处理读自光二极体的信号以产生蓝色、绿色以及红色的通道信号。; the second adjacent photodiode covered by the masking layer and located sufficiently near the first adjacent photodiode that at least some light admitted through the opening over the central photodiode is capable of reaching the second adjacent photodiode through the first adjacent photodiode. Circuitry is provided for reading the photodiodes and generating a blue, a green, and a red channel signal by processing signals read from the photodiodes.
