摘要
An image sensor includes a pixel array configured to generate a plurality of pixel signals, an analog to digital converter circuit coupled to the pixel array and configured to generate respective digital codes responsive to respective ones of the pixel signals, a plurality of memories, respective ones of which are configured to store respective bits of the digital codes, a signal processing circuit coupled to a plurality of memories and configured to generate analog signals responsive to the stored bits, each of the analog signals corresponding to multiple ones of the stored bits, and a comparator circuit configured to compare the analog signals to respective ones of a plurality of reference signals to generate digital signals corresponding to the multiple ones of the stored bits. Related image processing systems and methods are also described.
