Abstract

Image processing apparatus using common circuitry for different signals includes conversion circuitry for converting an input image signal into another signal form. First control circuitry is provided for giving first control information to the conversion circuitry to cause the conversion circuitry to convert the input image signal into, e.g., a compressed signal. Second control circuitry is provided for giving second control information to the conversion circuitry for causing the conversion circuitry to convert the input image signal into a signal adapted to be stored by a medium. Preferably, a D/A converter is used in common during photographing operations and during reproducing operations. The common circuitry avoids the use of separate circuits for conversion into different signal forms.
