PURPOSE:To make use of various kinds of supplementary processing methods for monochromatic image data by executing the supplementary arithmetic operation to obtain converted image data by enlarging, contracting, or rotating an original image consisting of color image data based on binarization data. CONSTITUTION:A transmission destination coordinate from a transmission destination coordinate generation part DSCAN is stored in a transmission destination coordinate register CPD, a transmission source coordinate integer part from a transmission source coordinate generation part SSCAN is stored in a transmission source coordinate integer part register CPS, and the fraction part is stored in a fraction part register CPSF. A data read part FBRD transmission color data corresponding to a supplied address, and this data is stored in a transmission destination color image data register IMGREG and binarized by a binarization part MAPALU. Thus binarized data is stored in a binarization data register MAPREG, then supplied to a supplementary table TABLE to select the supplementary table. The data in thus selected supplementary table is supplied to a barrel shifter SHIFT to cut out data. |
