PROJECTION APPARATUS, PROJECTION CONTROL APPARATUS, PROJECTION SYSTEM, AND PROJECTION STATE ADJUSTMENT METHOD

摘要

Considered is a case where an adjustment chart is projected larger than a screen that is a projection target and an outer frame is not projected on the screen. The position of a top side of the outer frame can be easily identified from an interval between intersections of a top side of the screen and sides of a rhombus. Similarly, the position of a right side of the outer frame can be easily identified from another interval, and a bottom side of the outer frame from still another interval.
