ACQUISITION METHOD OF GAMMA CHARACTERISTIC, ACQUISITION SYSTEM OF GAMMA CHARACTERISTIC, AND PROJECTION SYSTEM

摘要

PPROBLEM TO BE SOLVED: To provide an acquisition method of gamma characteristic which is possible to achieve high precision considering effect of flare. PSOLUTION: The method includes a process S2 which photographs a calibration pattern projected from a image projection part, a process S3 which creates a flare influence reduction pattern for reducing effect of flare based on the image of the photographed calibration pattern, a process S4 which photographs the flare effect reduction pattern projected from an image projection means, and a process S5 which calculates gamma characteristic of the image projection part based on the image of the photographed flare effect reduction pattern.
