Abstract
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.
