Zusammenfassung:PURPOSE:To prevent an adverse influence to a hue due to the high speed in a shutter speed by changing the amplification factors of respective chrominance signals according to the change of the shutter speed. CONSTITUTION:In a storing circuit 40, not only adjusting data for setting the optimum quantity of stop and the shutter speed but also hue adjusting data preset correspondingly for every shutter speed is stored. The control data of the amplification factor of a chrominance amplifier 41 is stored for every hue to the shutter speed. This control data is supplied to the amplifier 41 through an I/O interface circuit 38 from a central processing circuit 36. Accordingly, as the shutter speed is enhanced, even when the sensitivity of respective colors is changed, the level of the respective chrominance signals is compensated by the amplification factor opposite to the sensitivity characteristic.
