Abstract:
1. An image processing apparatus, which applies an adjusting process to an image that includes a pixel to be processed, said apparatus comprising: an extraction unit adapted to extract an image area with a predetermined size including the pixel to be processed; a variation calculation unit adapted to calculate a variation with respect to the pixel to be processed from signal values of pixels included in the image area; a variation time count calculation unit adapted to calculate a variation time count with respect to the pixel to be processed from the signal values of the pixels included in the image area; a definition unit adapted to define correspondence among the variation time count, the variation, and an adjusting level; and an adjusting unit adapted to calculate the adjusting level from the variation time count and the variation using said definition unit, and to apply an adjusting process to a signal value of the pixel to be processed by the calculated adjusting level, wherein said definition unit defines the correspondence so that the adjusting level progressively changes in accordance with different variation time counts or different variations.
