An image considering the visual field of a visual disorder person is reproduced
with high fidelity, and an image matching the visual field of a visual disorder
person is corrected to display a clear image, respectively by using visual information
conversion correction coefficients. Barriers of visual disorder persons can be
reduced. An input image for vision reproduction is corrected by converting values
of the XYZ chromaticity coordinates in accordance with the vision characteristics
data of the XYZ chromaticity coordinates for a simulated person. A reproduced image
with the visual situation of the simulated person is output in accordance with
the corrected input image.
