Patent ID: 8437028

Claim:
An image combining apparatus, which is configured to be connected with a white-board device, which has a viewing surface and is configured to scan a depicted image depicted by a user on the viewing surface, and to output scanned image data, and an image projecting device, which is configured to project image data on the viewing surface, based on projective image data, wherein the image combining apparatus, which is configured to combine the scanned image data of the depicted image with the projective image data, comprises: an image outputting section for outputting the projective image data to the image projecting device; an operation section for designating a position on a projected image; an image processing section for generating projective image data for displaying an image of a certain mark at a coordinate position corresponding to the position designated by the operation section so that the certain mark is displayed on the position designated by the operation section; a memory section for memorizing coordinate positions of two or more standard points determined on the viewing surface of the white-board device; and an image inputting section for receiving the scanned image data from the white-board device, wherein the image processing section is configured to obtain the respective coordinate position of the certain mark when the certain mark is aligned with each of the coordinate positions of the standard points, the image processing section is further configured to make correspondence with the respective coordinate positions of the certain mark and the coordinate positions of the two or more standard points respectively, whereby the image processing position recognizes the position of the projected image on the viewing surface of the white-board device.
