Abstract
A correlated double sampling apparatus includes a first processing unit and a second processing unit. The first processing unit is arranged for receiving a reset signal, a data signal, and a predetermined signal; obtaining a reset level of the reset signal and a first data level of the data signal in a first operation mode; and obtaining a second data level of the data signal, and comparing the second data level with the predetermined signal to generate a detection result in a second operation mode. The second processing unit is arranged for storing the reset level and the first data level in the first operation mode, and selectively correcting an output signal according to the detection result in the second operation mode, wherein the output signal is determined according to a level difference between the reset level and the first data level.
