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.

主权项

1. A projection apparatus comprising:
an image projection unit configured to project an image onto a projection target; an adjustment chart projection unit configured to project an adjustment chart indicating a projectable area; an image capturing unit configured to acquire a captured image of the projection target on which the adjustment chart has been projected; and a CPU configured to identify, using the captured image, a contour of the projectable area based on a part of the adjustment chart projected by the adjustment chart projection unit; wherein: the contour is a rectangle; and the adjustment chart includes:
at least one first point provided, excluding vertices, on each of contour segments of the rectangle; andat least two first lines having the first point at one end of each of the first lines.
