Abstract
A signal processing apparatus includes a correlated double sampling unit and a processing unit. The correlated double sampling unit is arranged for receiving a reset signal and a data signal, obtaining a reset level and a first data level corresponding to the reset signal and the data signal, respectively, and outputting an output signal according to a level difference between the reset level and the first data level. The processing unit is coupled to the correlated double sampling unit, and is arranged for receiving a second data level of the data signal and a predetermined level, and comparing the second data level with the predetermined level to generate a detection result indicative of quality of the level difference.
