PROBLEM TO BE SOLVED: To estimate correlation between frames when adjusting the contrast of each frame.

SOLUTION: An image processing device 10 includes: a depth information extractor 13 for extracting depth information of an Mth frame image of a three-dimensional moving image; a brightness extractor 12 for extracting a brightness component of the Mth frame image; a contrast extractor 15 for extracting the contrast component of the Mth frame image based on the brightness component of the Mth frame image; a gain generator 16 for calculating a contrast adjustment gain map CG of the Mth frame image based on the contrast component and the depth information of the Mth frame image; and a correlation estimator 20 for calculating an image correlation value between at least two frames including the (N-1)th frame and the Nth frame (N>0). The gain generator 16 estimates a contrast adjustment gain map EG of the Nth frame from the contrast adjustment gain map CG of the Mth frame image and the correlation value.
