One aspect of the present disclosure is an image processing device performing image stabilization of frame images shot by an imaging device. This device is provided with an acquiring unit, an image generating unit and a cropping unit. The acquiring unit acquires the plurality of frame images. The image generating unit stitches, among the plurality of frame images acquired by the acquiring unit, a first frame image and a second frame image, the second frame image being one frame image among several frames before and after the first frame image, to generate a composite image larger than a size of the first frame image and the second frame image. The cropping unit sets a cropping region to the composite image and outputs an image in the cropping region as an output frame image.

It is an object to generate a desired composite image in which a motion area of a subject is correctly composited. A difference image between a base target and an aligned swap target is generated (S), and an extracted contour in the difference image is determined according to the active contour model (S). The inner area of the contour and the outer area of the contour are painted with different colors to be color-coded so as to generate a mask image for alpha blending (S). Using the mask image thus generated, the swap target that is aligned with respect to the base target is composited with the base target of the base image by alpha blending (S).
