An image processing device, an image processing system, and an image processing method according to the present invention include a mask determining unit that determines a vertical relation in an overlapping area when a video window and a still image window overlap. As a result of a determination, if it is decided that the still image window overlaps as an upper window, the mask process is performed, and if it is decided that the still image window overlaps as a lower window, the mask process is not performed, thereby allowing an appropriate composite image to be obtained regardless of the vertical relation in the overlapping area of the video window and the still image window. |
