<p>Both a high signal-to-noise ratio (S/N) and a wide dynamic range of the output video signal of a one-CCD color television camera are realized. An image signal processing apparatus of an imaging device using a solid-state image sensor in which different color filters are arranged comprises an amplifying means for amplifying color signals outputted from the solid-state image sensor with a predetermined amplification factor, a separating means for separating the color signals amplified by the amplifying means into individual color signals, a white balance adjusting means for subjecting the separated color signals to white balance adjustment, a level detecting means for detecting a saturation level from the color signals subjected to the white balance adjustment depending on the amplification factor of the amplifying means, a correction signal generating means for generating correction signals from the other color signals than the color signal from which the saturation level is detected by the level detecting means, and a first adding means for adding the correction signals generated by the correction signal generating means to the color signals subjected to the white balance adjustment.</p> |
