More Information
Summary:An image correction device generates a corrected image for a viewer with low vision, by adding excessive emphasis which reduces image quality as perceived by a viewer having normal eyesight, to at least one of luminance gradation, luminance contour, and color tone of a pre-correction image. The image correction device includes: a controller which specifies, in a low vision mode which is an image correction mode for the viewer with low vision, a parameter that represents an amount of correction greater than an upper limit of an amount of correction which does not reduce the image quality as perceived by the viewer having normal eyesight when the pre-correction image is corrected; and an image processor which generates the corrected image by correcting the at least one of the luminance gradation, the luminance contour, and the color tone of the pre-correction image with the amount of correction represented by the parameter.
