Color mosaic filter layouts for enhanced camera performance

원문 (중국어)

An image sensing device includes a semiconductor substrate on which a first array of photodetectors is disposed. Readout circuits are disposed on the substrate and coupled to respective pairs of the photodetectors, and output signals from the respective pairs in a first mode, in which the signals are read out individually from each of the photodetectors, and in a second mode, in which the signals are binned together pairwise. A color filter layer disposed over the photodetectors includes a matrix of red, green, and blue tiles, such that in a first set of the pairs of the photodetectors, both the photodetectors are overlain by respective green tiles, while in a second set of the pairs of the photodetectors, one of the photodetectors is overlain by a first tile of a first color, while the other one of the photodetectors is overlain by a second tile of a different, second color.
