Title:
PROJECTION APPARATUS, INFORMATION PROCESSING APPARATUS, AND DRIVE CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2021/149479
Kind Code:
A1
Abstract:
The present invention suppresses burning of a spatial light phase modulator. A projection apparatus (1) comprises an illumination optical system (12) that emits light, an information processing unit (20) that generates a hologram pattern based on an input image, a spatial light phase modulator (14) that forms the hologram pattern generated by the information processing unit and allows light emitted from the illumination optical system to pass therethrough, and a projection optical system (16) that projects the output from the spatial light phase modulator onto a projection surface to project an output image. The information processing unit generates, for each predetermined frame, a new hologram pattern generated by shifting the hologram pattern in a predetermined direction.
