Controller, display device, eyeglass device and video system for controlling an eyeglass device based on an environmental factor

摘要

A controller for controlling an eyeglass device which performs an assistance operation for assisting in stereoscopically viewing a video includes: a first acquisition portion for acquiring first frequency information relating to a display frequency of frame images of the video; a second acquisition portion for acquiring second frequency information relating to an environmental factor which periodically varies in an environment where the video is viewed; and a generator for generating a reference signal to adapt the assistance operation of the eyeglass device to display of the frame image and periodic variation of the environmental factor on the basis of the first frequency information and the second frequency information.

1. A controller for controlling an eyeglass device which performs an assistance operation for assisting in stereoscopically viewing a video, comprising:
a first acquisition portion configured to acquire first frequency information relating to a display frequency of frame images of the video; a second acquisition portion configured to acquire second frequency information relating to an environmental factor which periodically varies in an environment where the video is viewed; a generator configured to generate a reference signal for adapting the assistance operation of the eyeglass device to display of the frame image and to periodic variation of the environmental factor based on the first frequency information and the second frequency information; and a transmitter configured to transmit the reference signal, wherein the transmitter transmits the reference signal at a transmission period which is longer than a display period of the frame image and which is longer than a blinking period of an illumination light source configured to illuminate a space where the video is viewed, and wherein the transmission period is a least common multiple of the display period of the frame image and the blinking period of the illumination light source.
