STEREOSCOPIC VIDEO DISPLAY SYSTEM, STEREOSCOPIC VIDEO PROJECTION DEVICE, ACTIVE SHUTTER GLASSES, AND PARALLAX AMOUNT CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To appropriately control a parallax amount in accordance with a viewing distance of a user wearing active shutter glasses.SOLUTION: A video size calculation unit 17 calculates a projected video size as the size of video projected on a screen 400. Then, a parallax amount control unit 15 controls a parallax amount between a left-eye image and a right-eye image using the calculated projected video size and a viewing distance D20 as a distance from active shutter glasses 200 to the screen 400.
