Abstract
An imaging device includes a plurality of photo-diodes that operate as optical pixels arranged in a plurality of columns on a single CMOS substrate. The outputs of the multiple pixel sensors, or photo-diodes, are examined to determine if a one pixel, or a region of pixels are in saturation. If so, then the pixel gain is adjusted to correct or compensate for the image distortion in the region. For example, the gain of the charging amplifier or operational amplifier can be adjusted to correct for saturation. This can be done in real-time since hardware is being tuned for the correction instead of software.
