Patent ID: 8729448

Claim:
A method for processing optical signals, the method comprising: generating one or more signals in response to sensed conditions determined by one or more pixels of a pixel array; controlling a transmission of the one or more signals from the one or more pixels to a capacitive element, the transmission controlled by passing the one or more signals through a transistor disposed between the one or more pixels and the capacitive element; generating a drive signal at the capacitive element in response to receiving the one or more signals; generating an increment signal at a comparator in response to the drive signal exceeding a reference signal; incrementing a count value in a counter in response to receiving the increment signal, the increment signal further activating circuitry to recharge the capacitive element controlling the drive signal; and reading the count value in the counter utilizing a summation function to further process the count value corresponding to the one or more signals in response to a time period elapsing.
