Abstract
Abstract There is disclosed an image processing apparatus provided with a converter for converting the input image signal into another signal form; a first unit for generating first control information for causing the converter to compress the input image signal; and a second unit for generating second control information for causing the converter to convert the input image signal into a predetermined signal format suitable for storage in a recording medium. These units avoids the use of separate circuits for conversion into different signal forms, so that the magnitude of circuitry can be reduced.
