<p>A semiconductor integrated circuit for image processing includes a playback luminance signal processing circuit, a playback chromatic signal processing circuit for receiving a recorded image signal, and a TV system conversion circuit for selectively converting a TV system to a different one. The chromatic signal played back is recorded. In another embodiment, the integrated circuit includes a playback luminance signal processing circuit for receiving an image signal for television, a TV system conversion circuit for selectively converting a TV system to a different one, and a recording chromatic signal processing circuit for receiving the output signal of the TV system conversion circuit. Since the semiconductor integrated circuit is arranged so as to perform the process of not solely playing back or recording an image signal but also converting the system, a synchronizing signal necessary for playback processing and a color subcarrier generating circuit necessary for system conversion can be put to common use. Therefore, accurate signal processing is made possible with simplicity in construction. <IMAGE></p> |
