Projection apparatus, geometric correction adjustment method, and program for geometric correction adjustment

摘要

A projection apparatus (1) includes a projection optical system (20, 16), an output display element (15), an operation unit (28) acquiring an adjustment instruction, a geometric correction adjustment unit (13a), and a geometric correction unit (13b). The output display element (15) having an element region (62) including pixels that modulate projection light by a quadrangular effective element region (64) in the element region (62). The geometric correction adjustment unit (13a) transforms the effective element region (64) to shift a vertex (641, 642, 643, 644) of the effective element region (64) along a side (646, 647, 648, 649), according to the adjustment instruction. The geometric correction unit (13b) performs an operation of projecting an input image on the effective element region (64).
