摘要： An electronic exposure control system for an active pixel CMOS image sensor includes a row decoder and a column decoder for respective row-wise and column-wise addressing of the image signal generating pixels. The decoders receive row and column addresses and control signals from a controller. The row addresses received by the row decoder are alternately switched between a predetermined row address for resetting the image signals of pixels in said row and another predetermined spaced apart row address for enabling the image signals of pixels in said selected row to be read out by the column decoder. By providing a predetermined sequence of row addresses, a “rolling shutter” can be created and/or the exposure time of the pixels can be selected to be different from the time to expose an entire frame. The image sensor can also be operated in an interlaced mode and/or specific areas on the image sensor can be selected to be reset and read out.
