Image control apparatus, image processing system, and computer program product

An image control apparatus that generates and outputs a drawing image includes an identification unit that uses position information of an object that is close to or in contact with a display device, which is controlled to display the drawing image, and determines whether the object corresponds to a drawing device; and an image generation unit that generates the drawing image using the position information of the object and outputs the generated drawing image. When the drawing device comes into contact with the display device, the image generation unit generates the drawing image using position information of the drawing device.
