Abstract: PURPOSE:To simplify the circuit constitution by inputting an output of an automatic gain control(AGC) circuit to an integration circuit with a different time constant, obtaining a flicker noise component from a difference output, storing the component to a memory and using its output as a suppression signal so as to apply feedback control to the AGC circuit. CONSTITUTION:An output signal of an AGC circuit 3 is integrated respectively by a 1st integration circuit 5 and a 2nd integration circuit 6. In this case, since the time constant of the integration circuits 5, 6 is set differently, flicker noise due to a fluorescent light or the like is generated, an output of the 1st integration circuit 5 is fluctuated corresponding to a period of flicker, an output of the 2nd integration circuit 6 is averaged independently of e flicker noise, and an output corresponding to a sensitivity difference due to the flicker noise is obtained by obtaining a difference of the outputs of the integration circuits 5, 6 at a comparator 7. Then the difference output is stored in a memory 11 and a correction signal VPL is outputted from the memory 11 in a timing to correct a delay due to the time constant of the integration circuit 5 and it is fed back to the AGC circuit 3 to control the difference of the integration circuits 5, 6 to be made zero. Thus, the circuit constitution is simplified.
