A three-panel projection apparatus in which display quality due to displacements of fixing positions of panels is improved is provided. By displaying position-adjusting-images of a plurality of colors formed in a plurality of different patterns and by selecting any of the patterns, the overall display frame is compensated for with a method corresponding to the selected adjusting images and displayed. Further, at least two of the adjusting images are arranged on the opposing corners of the display frame. Still further, the compensating method performs computation on the basis of a target pixel and its circumferential pixels so as to form a compensation pixel.
