Abstract:
When it is estimated that first average brightness of image information of a projection image is under second average brightness of image information of a source image having a single spatial frequency on which a normal compensation is performed, an area having brightness above the second average brightness in the image information of the projection image is increased, and when it is estimated that the first average brightness is above the second average brightness, an area having brightness under the second average brightness in the image information of the projection image is increased.
