Abstract
A color-converted image forming apparatus is disclosed which permits formation of a color conversion matrix for each of the input images and allows consequent production of an output image which has undergone desired conversion by a relatively simple operation. This apparatus stores image data introduced via an interface 11 in an image memory 13 and, at the same time, analyzes picture elements of an introduced image with a counter 12 to extract a plurality of characteristic magnitudes, and stores the results of the analysis in a characteristic magnitude memory 21. The extracted plurality of characteristic magnitudes are read out together with preset characteristic magnitudes of conversion into a coefficient arithmetic device 22, in which a coefficient for conversion is calculated from the data. The row of coefficients of conversion thus obtained by the calculation are stored in a coefficient row memory 23. A converting counter 14 sequentially reads image data out of the image memory 13 and imparts color conversion thereto with the aid of the row of coefficients for conversion stored in the coefficient row memory 23. The image data which have undergone the color conversion are emitted to a print mechanism 4. The characteristic magnitudes for conversion are stored in a ROM 32 and an IC card 41.
