IMAGE PROCESSING APPARATUS AND METHOD, RECORDING MEDIUM, AND PROGRAM

An image processing apparatus includes an edge-direction detector that detects an edge direction in an original image; a confidence detector that detects a confidence of the edge direction; a contrast detector that detects a contrast intensity; a texture-contrast-weight setter that sets a texture-contrast weight; an edge-contrast-weight setter that sets an edge-contrast weight; a texture-weight setter that sets a texture weight; an edge-weight setter that sets an edge weight; a texture filter that performs texture filtering to generate a texture-filter image; an edge filter that performs edge filtering to generate an edge-filter image; a texture combiner that combines the original image and the texture-filter image to generate a texture-combination image; and an edge combiner that combines the texture-combination image and the edge-filter image to generate an edge-combination image.
