Claim Text:
1. An image display device to which an image is input, comprising: a processor configured to act as: a projection device adapted to project the image on which the correction is performed by the correction section, if the aspect ratio of a projection object is between 4:3 and 16:10 and the aspect ratio of the image is 4:3, the correction section performs correction so that the upper side and the lower side of the corrected image coincide with the upper side and the lower side of the projection object, and the left side and the right side of the corrected image is narrower than the left side and the right side of the projection object, and if the aspect ratio of the projection object is between 4:3 and 16:10 and the aspect ratio of the input image is 16:10, the correction section performs correction so that the left side and the right side of corrected image coincides with the left side and the right side of the projection object, and the upper side and the lower side of corrected image is narrower than the upper side and the lower side of the projection object, the correction value selection section selects one of the correction values corresponding to an aspect ratio equal to the aspect ratio determined by the aspect ratio determination section and the correction value corresponding to the aspect ratio having a difference from the aspect ratio determined by the aspect ratio determination section within a range determined in advance out of the plurality of correction values stored in the correction value storage device, and selects a correction value determined in advance in a case in which there is no correction value to be selected in accordance with the aspect ratio determined by the aspect ratio determination section.
