PROBLEM TO BE SOLVED: To adjust gradation from stored images if a storage region for images is small.SOLUTION: Gradation pixels with various different intensities are generated by performing more than one type of smoothing on a reference image, a gradation image is created by selecting a plurality of gradation pixels on an object distance of the reference image, a gradation adjusting section generates re-gradation pixels with various different intensities by performing more than one type of smoothing on the stored reference image, and re-adjusts the gradation processing based on the result of comparison between the pixels of the gradation image and the re-gradation pixels.SELECTED DRAWING: Figure 1 |
