To prevent any variation of the grayscale to be originally present from becoming unclear, diminishing banding that is generated when an image including a gradation is displayed. An image processing device obtains image data of an original image including plural pixels, obtains an evaluation value that represents the possibility of the generation of the banding on the basis of the color distribution of a noted area including a target pixel that is any one of the plural pixels, produces an intermediate image of which the color of the target pixel is corrected on the basis of the evaluation value, and causes a corrected image to be output on the basis of the produced intermediate image. A correction amount of the color of the target pixel is varied in accordance with the evaluation value, in the correction of the color.
