Abstract
A digital correlated double sampling (CDS) circuit includes a first latch unit, a second latch unit and a calculating unit. The first latch unit stores digital reset component data and digital image component data by latching a count signal in response to a first control signal. The second latch unit stores the digital reset component data by latching an output of the first latch unit in response to a second control signal. The calculating unit generates digital effective image data by subtracting the digital reset component data from the digital image component data.
