Abstract
A digital correlated double sampling circuit includes a first latch circuit, a second latch circuit, a decision circuit, a delay control circuit and a calculating circuit. The first latch circuit stores first reset component data. The second latch circuit stores second reset component data and stores image component data based on a selected comparison signal during an image interval. The decision circuit outputs a decision signal by determining identity of the first reset component data and the second reset component data during the reset interval. The delay control circuit outputs the reset comparison signal and outputs one of the first image comparison signal and the second comparison signal as the selected comparison signal. The calculating circuit generates effective image data by subtracting the second reset component data from the image component data and sequentially outputs the effective image data.
