PROJECTION SYSTEM, IMAGE GENERATION PROGRAM, INFORMATION PROCESSOR AND IMAGE GENERATION METHOD

摘要

PROBLEM TO BE SOLVED: To improve the detection accuracy of a user operation to a projection device.SOLUTION: A projection part projects a projection image to a projection surface. An imaging part images an imaging area representing an imageable area, and generates a picked-up image. A first calculation part calculates first coordinates for specifying the position of the imaging area to the projection image from the picked-up image and the projection image. A second calculation part calculates, from the projection image, second coordinates for specifying the position of a non-operation object image representing an image that is not an object of a user operation to the projection image. A position determination part determines an arrangement position for arranging an operation object image representing an image to be an object of a user operation in the projection image from the projection image, the first coordinates and the second coordinates. A projection image generation part generates a projection image in which the operation object image is arranged to the arrangement position. A projection control part controls projection of the projection image by the projection part.
