ABSTRACT:
An image-processing device of the invention can appropriately correct a gradation of an image to be processed in accordance with the image. Thus, it divides the image into plural small areas; generates image information indicating a characteristic of the image for each small area; determines an evaluation value indicating luminosity of each pixel constituting the image, according to the image information generated for each small area and image information generated for each of adjacent small areas to the each small area; and performs an image processing on each pixel of the image according to the determined evaluation value. A digital still camera of the invention can appropriately correct a gradation of an image created by shooting in accordance with the image. Moreover, an image-processing program and an image-processing method of the invention realize appropriate gradation correction in accordance with an image to be processed.
