Abstract:
1. A calibration device comprising: a communication section which communicates with a display device which displays images on a screen; a light sensor arranged in a position to receive transmitted light of a lens of shutter glasses; a signal processing section which processes an output signal of the light sensor; a processing section which determines a timing of opening and closing of shutters; and a shutter driving section which operates the opening and closing of shutters of shutter glasses in accordance with the timing of the opening and closing of shutters determined by the processing section, wherein the communication section receives a standard pulse which shows a timing when images are switched from the display device, and the processing section determines an appropriate correction amount τ of the timing of the opening and closing of shutters based on a phase difference between the output signal of the light sensor and the standard pulse.
