Eyeglass device and video system

摘要

An eyeglass device for assisting in viewing a video to be stereoscopically perceived includes an optical filter portion with left and right filters for adjusting light amount to be transmitted to left and right eyes, respectively and a controller for controlling adjustment operation of the light amount by the optical filter portion, wherein the controller switches a control mode of the optical filter portion between a first control mode of controlling the optical filter portion so that the adjustment operation becomes synchronized with display of a frame image of the video and a second control mode of controlling the optical filter so that that the adjustment operation becomes slower than a frame rate of the video to make a viewer perceive the adjustment operation which is asynchronous with the display of the frame image.

1. An eyeglass device for assisting in viewing a video to be stereoscopically perceived comprising:
an optical filter portion including a left filter configured to adjust a light amount which is transmitted to a left eye and a right filter configured to adjust a light amount which is transmitted to a right eye; and a controller configured to control adjustment operation of the light amount by the optical filter portion, wherein the controller switches a control mode of the optical filter portion between a first control mode of controlling the optical filter portion so that the adjustment operation becomes synchronized with display of a frame image of the video and a second control mode of controlling the optical filter portion so that a viewer perceives the adjustment operation asynchronous with the display of the frame image, and wherein the controller controlling the adjustment operation under the second control mode sets and repeats an adjustment period which is longer than a display period of the frame image and evenly divided into a first period for maximizing a light amount transmitted to one of the left and right eyes and a second period for minimizing a light amount transmitted to the one of the left and right eyes.
