1. An image processing device comprising:
a background manager configured to:
determine a foreground region of an image including a target object and;
determine a background region of the image that is without the target object in the image based on image data, the image data including pixel values of pixels included in the image and depth map data, the depth map data comprising disparity values of the pixels; and
a target object manager configured to determine a reference position of the target object based on count values obtained by counting foreground pixels included in the foreground region in a preset direction at a plurality of positions, and to detect the target object corresponding to a preset shape within a region of interest that is set based on the reference position.
