Abstract:
A microcomputer outputs correction data. A shading correction circuit performs a shading correction to a digital image signal using the correction data outputted from the microcomputer. A YC processing circuit generates a video signal from the digital image signal having undergone the shading correction, performs processing such as a gamma correction to the generated video signal, and outputs the video signal having undergone the processing such as the gamma correction.
