ABSTRACT:
The image processing device is designed to retrieve a predetermined data section from data composing a first image, to retrieve a coefficient value from a predetermined table using a value of the retrieved data section as an index, and to subject the first image to image processing using the coefficient value. This allows alteration of the degree of anti-aliasing depending on the luminance of an image (e.g., luminance of an edge portion), extensive reduction in jaggedness at the edge portions having a high luminance which tends to make flicker visually prominent, and reduction in the cost and size of the device.
