Abstract
A system and method for processing optical signals. A photo detection signal is generated in response to sensed conditions determined by one or more pixels of a pixel array. A drive signal is generated for a comparator. An increment signal is generated in response to the drive signal exceeding a reference signal. A counter is incremented in response to receiving the increment signal. The increment signal further activates a switch to reset a capacitor controlling the drive signal. A count value in the counter is read utilizing a summation function to further process the count value corresponding to the photo detection in response to a time period elapsing.
