Image processing apparatus and method, recording medium, and program |
摘要 |
An image processing apparatus including a contrast detector that detects a contrast intensity of a pixel in a first image; a flat-intensity detector that detects a flat intensity of the pixel; an edge-intensity detector that detects an edge intensity of the pixel; a flat-weight setter that sets a flat weight for the pixel; an edge-weight setter that sets an edge weight for the pixel; an attenuator that attenuates components in a predetermined frequency band of the first image to form a second image; a first combiner that combines the first and second images to form a third image using weights based on the flat weight; an edge enhancer that enhances edges in the third image to form a fourth image; and a second combiner that combines the first and fourth images using weights based on the edge weight.
