Abstract
An image processing apparatus includes a degree-of-degradation detector, a degree-of-degradation estimation unit, a correction system selector and a gradation correction unit. The degree-of-degradation detector detects a degree of degradation of an image data. The degree-of-degradation estimation unit estimates a dispersion of the degree of degradation in the image data. The correction system selector selects either a first gradation correction system or a second gradation correction system in accordance with the dispersion of the degree of degradation. The gradation correction unit performs gradation correction of the image data based on either the selected first or second gradation correction system.
