Abstract
There is disclosed an image processing apparatus for processing an image signal in which the mode of image processing is rendered variable to adapt to plural input devices. More specifically, a conversion matrix circuit receives image signals from one of a plurality of different input devices and converts the image signals into corrected additive primary color signals red, green and blue. The conversion matrix circuit compensates for any differences in the spectral characteristics of the different input devices. The matrix includes a plurality of conversion tables stored in memory for performing the conversion. A selected one of the conversion tables is addressed by the image signals.
