CONTROL DEVICE, PROJECTION DEVICE, CONTROL METHOD, AND CONTROL PROGRAM
Document Type and Number:
WIPO Patent Application WO/2021/039002
Kind Code:
A1
Abstract:
Provided are a control device, a projection device, a control method, and a control program with which it is possible to suppress magnification chromatic aberration without causing projected images to be missing. A system control unit (14) performs a reduction process for reducing, at a first reduction rate, input image data g1 that is inputted to a display unit, and an image shift process for shifting the positions of R image data (131R) and B image data (131B) of specific color components included in the reduced image data g13 obtained by the reduction process, and generates corrected image data g2. The system control unit (14) inputs this corrected image data g2 to the display unit and causes a corrected image based on the corrected image data g2 to be projected onto a screen SC.
