Image-sensing array with autofocus pixels and enhanced resolution

원문 (중국어)

An image sensing device includes a semiconductor substrate and a first array of photodetectors disposed on the substrate. Readout circuits, which are disposed on the substrate, are coupled to respective pairs of the photodetectors, and are configured to output signals from the respective pairs in at least a first mode, in which the signals are read out individually from each of the photodetectors, and a second mode, in which the signals are binned together pairwise. A color filter layer includes a matrix of red, green, and blue tiles overlying respective pairs of the photodetectors. A second of array microlenses, overlying the color filter layer, includes first microlenses overlying the respective pairs of the photodetectors that are overlain by the red and blue tiles and second microlenses individually overlying each of the photodetectors in the respective pairs that are overlain by at least some of the green tiles.
