Abstract: A corrector corrects a main image acquired by an image acquirer based on correction setting acquired by a correction setting acquirer, and stores corrected main image in a buffer. An unused area detector detects the area that has not stored the corrected main image in the buffer, and transmits the result to a sub-image selector. The sub-image selector selects, among sub-image candidates registered in a sub-image information memory, a candidate that can be displayed on the unused area and has the highest priority as a sub-image. The sub-image controller executes a program stored in the sub-image displaying program memory, and displays the selected sub-image on the unused area.

Abstract: An image projection apparatus includes an item selection unit which selects one of items to be image-adjusted, a first image generation unit which generates a plurality of images acquired by subjecting a target to be projected to image adjustment, in different adjusting levels, the image adjustment corresponding to an item selected by the item selection unit, a first image projection unit which projects said plurality of images generated by the first image generation unit, an image selection unit which selects any one of said plurality of images projected by the image projection unit, and a second image projection unit which projects an image selected by the image selection unit.

Abstract: An apparatus includes a projection system having a spatial light modulator and projection lens and configured to project a light image, an image capture system having an image capture lens and CCD and configured to capture a screen-direction image, a distance measuring sensor and distance measuring processing section configured to detect a distance and angle to the screen, a control section configured to, while extracting a screen frame position from the image obtained by the image capture system and, from respective detection results of the distance measuring and an angle-of-view detections, obtain a corrected value while referring to a correction table of a memory section storing corrected values of a parallax of the projection system and image capture system in a table form and match an image projected by the obtained corrected value to a screen frame position extracted.
