Title:
PROJECTION DEVICE AND CONTROL METHOD THEREOF, AND CONTROL PROGRAM
Document Type and Number:
WIPO Patent Application WO/2020/021868
Kind Code:
A1
Abstract:
Provided are: a projection device which is capable of highly accurately correcting a projection image that has been matched to a color of the projection plane; a control method thereof; and a control program. A system control unit (8) sequentially selects each of areas T1-T7 for detection that are set in a projection range AR, and projects test light onto the selected area for detection from a common optical system (3). In a state in which the test light is projected, the system control unit (8) acquires, from an image capturing element (6), a test light image that is a captured image of the area for detection onto which the test light is projected, and generates correction data for correcting the color of an image that is to be projected onto a screen SC on the basis of a color difference between the acquired test light image and the test light. The system control unit (8) inputs, to an optical modulation element (44), image data corrected on the basis of the correction data, and projects an image on the basis of the image data.
