1. An image processing device comprising: a detection section which detects motion of the image processing device; a blend ratio calculation section which calculates a blend ratio of a first motion compensation image to a second motion compensation image, the first motion compensation image and the second motion compensation image being determined from a first motion vector and a second motion vector each indicating motion between frames, respectively, based on the motion of the image processing device detected by the detection section; a blend section which generates a motion compensation image by blending the first motion compensation image and the second motion compensation image in accordance with the blend ratio calculated by the blend ratio calculation section; and an addition section which adds the motion compensation image generated by the blend section to a target image.
