An image-processing apparatus for processing the image data input from an image-handling
device and then outputting the image data to another image-handling device. The
apparatus comprises a black-adaptation correction device. The black-adaptation
correction device corrects the image data in consideration of the fact that adaptation
to black varies from person to person, if the darkest points of the image-handling
devices differ from each other. Since the image is so corrected, the colors of
the images produced by the image-handling devices look almost the same in spite
of the fact that the darkest points of the image-handling devices differ from each other.
