Abstract

An improved color image sensor (100) semiconductor integrated circuit (IC) where photo sites (111-124) of a particular color receive an independent electronic shutter control (300) signal which allows the exposure time of pixels corresponding to each color to be set independently. The embodiments aim to improve image quality under lower illumination conditions by improving signal-to-noise ratio in the color channels having lower illumination, and permit some manufacturing variation in the sensor IC, in the color filter array (CFA), and in the optical component manufacturing processes. The invention may be particularly useful in portable digital image capture systems, such as the digital camera, but may also find use in color scanners and certain color copiers.
