A signal processing apparatus for an optical disc with a first type region and a second type region includes a processing module and a determining unit. The processing module is used for transforming an input signal to generate a first output signal according to a first amplifying gain, or to amplify the input signal to generate a second output signal according to a second amplifying gain, wherein the input signal is derived from an optical pickup head. The determining unit is coupled to the processing module and arranged to control the processing module to output the first output signal when the input signal is derived from the first type region. Also, the determining unit outputs the second output signal when the input signal is derived from the second type region.
