Abstract:
1. An image sensor, comprising: a pixel array located on a first portion of an integrated circuit (IC), the array including a plurality of pixels arranged in rows, wherein each pixel is configurable to output a first signal in response to illumination during each of multiple imaging cycles, and as to each pixel, the part of an imaging cycle during which the first signal is output depends upon an intensity of illumination of that pixel; a first group of pixel output lines, wherein each of the first group of pixel output lines corresponds to a different row of the array and is in communication with at least two of the pixels in the corresponding row; a signal generator configured to output a time-varying, multi-bit counter signal; a first group of multi-bit random access memory (RAM) storage elements displaced from the array on the IC, wherein each of the RAM storage elements
