Abstract:
An image processing apparatus for carrying out predetermined transformation processing on an input comprising component values of image data produced as gradation-color-specification data composed of color components of an image, thereby representing said image as a set of picture elements arranged to form a dot matrix, producing an output from said transformation processing and carrying out transformation based on a relation between said input and said output to correct a balance of color, said image processing apparatus employing a characteristic uniforming means wherein a distribution of said gradation-color-specification data is found for each of said color components, said characteristic uniforming means treats only picture elements approximated by said gradation-color-specification data for each of said color components as an object for finding said distribution, a slippage among said color components is recognized and said recognized slippage is used as a basis for making characteristics uniform among said color components.
