A pipeline row operation method of CMOS image sensors

[摘要] In this paper, we present a pixel array operation method of CMOS image sensor that enables pipeline processing of pixel operations. The sensor frame rate constraint from the delay of pixel array control lines is much relieved by manipulating control phases of adjacent pixel rows simultaneously. An analog frontend readout circuit is proposed to support the row pipeline operation pixel readout. A prototype image sensor was designed with its performance characterized and analyzed.
