IMAGE PROCESSING DEVICE, IMAGE DISPLAY DEVICE, IMAGE PROCESSING METHOD, AND IMAGE DISPLAY METHOD

摘要

An apparatus includes an edge width detection circuit which detects an edge portion of image data and outputs an edge width of the detected edge portion, a ratio control amount generation circuit which generates a ration control amount in accordance with the edge width, a ratio generation circuit which generates a conversion ratio in accordance with the ratio control amount, and a pixel number conversion circuit which performs a conversion of pixel number of the image data using the conversion ratio, thereby enhancing sharpness of the edge portion in proper quantities.
