Abstract
Through an image pick-up lens 1, image light is focused on an image pickup surface of an image pickup unit 2 for which a primary color filter is provided. An electrical signal removed from the image pickup unit 2 is supplied to an A/D conversion circuit 3 to be converted into raw data of each primary color and is supplied to a first camera signal processing circuit 61 without any change. In the first camera signal processing circuit 61, only basic video signal processing such as gamma-correction is performed. Then, the raw data of each primary color processed in the first camera signal processing circuit 61 is stored in a picture memory 4. The raw data of each primary color stored in the picture memory 4 is supplied to a magnification-reduction circuit 94 functioning as a first resolution conversion processing circuit for correcting the chromatic aberration of a lens.
