1. An image processing device comprising:
a video acquisition unit that acquires video captured by an image capturing unit;
a movement amount identification unit that identifies the amount of movement of the image capturing unit that is based on vibration applied to the image capturing unit based on an output signal from a sensor for detecting vibration applied to the image capturing unit or a difference between frames of the acquired video;
an object detection unit that detects an object of interest from within frames of the acquired video;
a motion vector detection unit that detects a motion vector of the object of interest between the frames of the video;
a cutout position determination unit that determines a cutout position for cutting out an image of a predetermined size from each of the frames of the acquired video and that determines an object cutout position moved according to a composite vector obtained by combining the motion vector of the object with a correction vector for canceling out a blur caused by vibration and a background cutout position moved according to the correction vector; and
an image composition unit that combines image data of the object cut out from the object cutout position with image data of a background cut out from the background cutout position excluding the object.
