ABSTRACT:
In an image signal processing apparatus which processes image signals, a plurality of different kinds of digital image signals are formed by delaying a digital image signal which was obtained by digitizing an analog image signal. When new digital image signals are formed using the plurality of different kinds of digital image signals, the apparatus is controlled so that a power-consumption state of at least one of a circuit for forming digital image signals and a circuit for delaying digital image signals is lower during a predetermined time period within the analog image signal. It it thereby possible to reduce power consumption of the apparatus, and to simplify the circuitry of the apparatus.
