Abstract
A digital image signal processing circuit for use in a VTR with camera has a signal input terminal to which an image pickup output signal or a video signal is supplied, an analog to digital converter for producing a digital image pickup output signal based on the image pickup output signal or a digital video signal based on the video signal, a digital signal processing portion including first, second and third digital signal processing circuit blocks, a system controller for conducting the change of operation, the change of circuit configuration or the change of circuit coefficient in each of the first, second and third digital signal processing circuit blocks, and signal output terminals from which recording luminance and carrier chrominance signals produced by the digital signal processing portion are derived. Each of the first, second and third digital signal processing circuit blocks performs efficiently various kinds of digital processing to the digital image pickup output signal or the digital video signal.
