An image processing apparatus, comprising:

• input image data storing means for storing a plurality of image data read for each of more than two color constituents;
• first correction value storing means for storing correction values constituted by a plurality of correction value data which individually correct the input image data from this input image data storing means in units of color constituents;
• data order operation means for resorting the correction values data from this correction value storing means in a data order in units of color constituents according to a command that specifies the output order of the color constituents;
• second correction value storing means for storing the correction values from this data order operation means;
• correction operation means for correcting the plurality of input image data for each color constituent based on the correction value data from the second correction value storing means;
• and
• output data storing means for storing and outputting the corrected image data from this correction operation means.

An image processing apparatus, comprising:

• an image reading component for electrically reading an original image for each of more than two color constituents by photoelectric conversion means;

• output image data storing means for storing and outputting the corrected image data from this correction operation means.

An image processing apparatus, comprising:

• input image data storing means for storing a plurality of input image data read for each of more than two color constituents;
• image processing mode selecting means for selecting a color mode which outputs the input image data as data of a plurality of color constituents and a monotone mode which outputs as data of one color constituent;
• correction value storing means for respectively storing color correction values constituted by a plurality of correction value data for correcting the input image data for each color constituent when in color mode, and a plurality of monotone correction values constituted by a plurality of correction value data for correcting the input image data when in monotone mode;
• correction operation means for correcting the input image data based on the color correction values which sequentially correspond to each color constituent when in color mode, said correction operation means correcting the above input image data based on the above monotone correction values which correspond to the input image data when in monotone mode;
• output image data storing means for storing the corrected image data from the first second correction operation means;
• and
• data order setting means provided between the input image data storing means and the output image data storing means, said data order setting means changing the order of the correction value data according to a command that specifies the output order of the color constituents when in color mode.

An image processing method, comprising:

• an image data generation step in which a plurality of image data read for each of more than two color constituents is stored in an input image data storing means;
• a correction value storing step in which correction values are stored, from a first storing means which stores in advance a plurality of correction values constituted by a plurality of correction value data for correcting the above input image data for each color constituent, into second correction value storing means, in a data order according to a command that specifies the order of output of the above color constituents;
• a correction operation step in which the input image data read from the input image data storing means is operated on based on the correction values read from the second correction value storing means for each color constituent;
• and
• a data output step in which the image data after correction which was obtained from this correction operation step is output.
