Abstract
It is an object of the present invention to provide a video signal processing device, which can produce a digital video signal, excellent in image quality, fully utilizing effective picture elements of the imaging element, without performing a special control of an imaging element driving unit. In accordance with a contour correction gain calculated based on a compression ratio detecting signal outputted from an image compressing unit, a contour correction unitcan carry out a contour correction on a compressed image. Accordingly, an NTSC/PAL encodercan output a preferable video signal, which has been subjected to an appropriate contour correction. Moreover, a digital outputting unitoutputs an uncompressed video signal, and therefore can provide a preferable video signal without deteriorating the effective picture elements of an imaging element.
