An image processing device of the present invention comprises a storage section for storing first image data obtained by imaging in front of the imaging device body or using a telephoto lens, and second image data obtained by imaging behind the imaging device body or using a wide-angle lens; a movement pattern detection section for processing the first image data to detect a movement pattern of the first image represented by the first image data; a movement pattern determination section determining whether or not the movement pattern of the first image is unstable movement; and an image processing section for rewriting a part of the first image data, for which it has been determined by the movement pattern determination section that the movement pattern of the first image is unstable, using the second image data.
