Patent ID: 7911500

Claim:
An image processing device comprising: 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, the image captured by the image capture device being an image of a first reference pattern that is projected by the projecting device, the first reference pattern indicating an effective projecting range of the projecting device; a color converting unit that extracts the first reference pattern from the acquired image, and performs a color conversion on the extracted first reference pattern, the color conversion converting frames of the first reference pattern from a first color to a second color; an enlarging/reducing unit that changes a size of the color-converted first reference pattern based on a ratio between a maximum effective imaging range of the image capture device and the effective projecting range of the projecting device, the color-converted first reference pattern having the changed size being a second reference pattern; and an output unit that outputs the first reference pattern and the second reference pattern, the second reference pattern superimposed on the first reference pattern.
