Projection Apparatus, Geometric Correction Adjustment Method, and Storage Medium Storing Codes for Geometric Correction Adjustment

摘要

A projection apparatus includes a projection optical system, an output display element, an operation unit acquiring an adjustment instruction, a geometric correction adjustment unit, and a geometric correction unit. The output display element having an element region including pixels that modulate projection light by a quadrangular effective element region in the element region. The geometric correction adjustment unit transforms the effective element region to shift a vertex of the effective element region along a side, according to the adjustment instruction. The geometric correction unit performs an operation of projecting an input image on the effective element region.

1. A projection apparatus comprising:
a projection optical system configured to project projection light on a projection target object; an output display element having an element region including a plurality of pixels that modulate the projection light and configured to generate a projection image configured to be projected on the projection target object based on an input image by a quadrangular effective element region included in the element region; an operation unit configured to acquire an adjustment instruction from a user to adjust the effective element region in the element region; a geometric correction adjustment unit configured to transform the effective element region in the element region to shift a vertex of the effective element region along at least one side of two sides, each of the two sides having one end that is the vertex to be shifted, according to the adjustment instruction input to the operation unit; and a geometric correction unit configured to perform an operation of projecting the input image on the effective element region.
