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.
Claims24
An image input apparatus comprising a solid-state imaging device for capturing an image of a subject, and a signal processing unit for processing an image signal that the solid-state imaging device outputs, wherein
- the solid-state imaging device includes:
- a plurality of filter units made of an inorganic material, each filter unit being operable to transmit a corresponding one of color components of light;
- and
- a plurality of light receiving units arranged two-dimensionally in a semiconductor substrate, each light receiving unit being operable to receive one of the color components of light transmitted through a corresponding one of the filter units, and
- the signal processing unit corrects the image signal in accordance with the color components and positions in the captured image.
