PROBLEM TO BE SOLVED: To suppress reduction in quality of second image data.SOLUTION: An image process device comprises: a first expansion rate calculation part that calculates a first expansion rate on the basis of a gradation value included in first image data; a second expansion rate calculation part that calculates a second expansion rate on the basis of a gradation value included in second image data; a first expansion part that corrects the gradation value included in the first image data on the basis of the first expansion rate, and expands a distribution range of luminance of the first image data; a second expansion part that corrects the gradation value included in the second image data on the basis of one expansion rate selected from the first expansion rate and the second expansion rate, and expands a distribution range of luminance of the second image data; and a synthesis part that generates synthesized image data synthesizing the first image data having the gradation value corrected by the first expansion part with the second image data having the gradation value corrected by the second expansion part. |
