Look ahead rolling shutter system in CMOS sensors

摘要: A shutter system for a pixel array is disclosed. The includes read shift register, first and second reset registers, plurality of logic gates. register configured to sequentially count rows the from top bottom, such that generates pointer. bottom. provides pointer allowing pixels in row indicated by allows prior reading time difference between indicates an exposure time. provide pointer, which enables without generating any flashes when increased. gates direct outputs registers each array.
