Zusammenfassung:	The present invention relates to an image processing apparatus capable of performing edge preserving smoothing processing with less operations, an image processing method, and a program. The block-histogram calculation unit 113 calculates the number of pixels, as a block histogram, included in each of luminance blocks which are obtained by dividing a luminance image in a spatial direction and a luminance direction. The block-integration value 115 calculates an integration value of luminance values of the pixels included in each of the luminance blocks as a block integration value. The weighted product-sum unit 117 calculates a general-luminance value representing average luminance of an object region to which a pixel being processed belongs using the block integration value, the block histogram, and a luminance value of the pixel being processed. This invention is applicable to digital video cameras.
