Abstract

An image processing device includes: a connecting unit that connects a projecting device and an image capture device, at least one of the projecting device and the image capture device having an adjustable position; an acquiring unit that acquires an image captured by the image capture device capturing an image of a reference pattern that is projected by the projecting device and indicates an effective projecting range of the projecting device; a color converting unit that extracts the reference pattern from the captured image, and performs a color conversion on the extracted reference pattern; an enlarging/reducing unit that enlarges or reduces the color-converted reference pattern in accordance with the ratio between the maximum effective imaging range of the image capture device and the effective projecting range of the projecting device; a superimposing unit that superimposes the enlarged or reduced reference pattern on a reference pattern yet to be projected; and an output unit that outputs the reference pattern superimposed by the superimposing unit to the projecting device.
