摘要：PROBLEM TO BE SOLVED: To provide an inexpensive projector which takes antiglare countermeasures reducing wrong decisions and which can focus and color adjust, while the constitution is simple. SOLUTION: This projector 1 projects a selected image via a projection lens 16 and an image forming part 14 forms an image, composited of the selected image and a reference image. Further, a control part 10 projects the composite image to a projection surface a specified timing, in place of the selected image. Reflected light from the projection surface of the composite image is received by a photodetection sensor 21 and the projection state is controlled by the control part 10 according to the photodetection result.
