ABSTRACT:
An image processing apparatus applied to an image processing system wherein a plurality of image input units and a plurality of image output units are used. A spatial frequency characteristic conversion section receives a spatial frequency characteristic in a preparation process of image data from an image input unit or its driver and a spatial frequency characteristic of a selected image output unit from an output device information storage section. An ideal transfer characteristic of the whole system is previously stored in the spatial frequency characteristic conversion section and a transfer function of the spatial frequency characteristic conversion section itself is set so as to realize the ideal transfer characteristic.
