Abstract:
1. A solid-state image-capturing apparatus that converts light, which is reflected from a subject and is incident via an image-capturing lens, into an electrical signal, the solid-state image-capturing apparatus comprising an image processing unit that performs edge enhancement on a digital video signal that is generated based on an analog video signal, which is obtained from the light captured by an image-capturing device and amplified by a predetermined analog gain, the edge enhancement being performed based on position information on each pixel of the image-capturing device and the analog gain wherein, when using, as the position information, coordinates indicated by a two-dimensional vector with reference to a pixel at a center of the image-capturing device, a correction-coefficient calculating unit calculates a first value obtained by multiplying a predetermined coefficient by square of a value of horizontal position information x contained in the position information and a second value obtained by multiplying a predetermined coefficient by square of a value of vertical position information y contained in the position information, further multiplies a gain coefficient by a sum of the first value and the second value, and sets an obtained value as a correction coefficient.
