MULTI-DISPLAY SYSTEM, IMAGE DISPLAY DEVICE, SCREEN CONTROL METHOD, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a multi-display system capable of easily correcting unevenness as a whole multi-display screen.SOLUTION: A multi-display system 10 includes: a plurality of image display devices 1 and a computer 4 for control, and each image display device 1 includes: a correction data holding part 122 for holding correction data for an own screen for correcting luminance unevenness in the screen of an own device; a reference data holding part 17 for holding target luminance data for an own screen showing target luminance after correction based on the correction data for an own screen; and a correction arithmetic part 123 for generating an image signal for display by correcting an image signal input from the outside by using the correction data for an own screen. The computer 4 for control acquires the correction data for an own screen and the target luminance data for an own screen from each image display device 1, and calculates the correction data for a multi-screen for correcting the luminance unevenness in the multi-display screen, and the correction arithmetic part 123 generates an image signal for display by using the correction data for a multi-screen.
