| 摘要 | A wireless signal transmission device of the present invention includes a wireless signal transmission section for, when an image display device displays a 3D image, (i) a sync signal indicative of timing at which a right-eye image and a left-eye image included in the 3D image are switched and (ii) an optical shutter control signal for controlling optical shutters of 3D image glasses which optical shutters alternately transmit and shut the right-eye image and the left-eye image, and for, when the image display device displays an image other than a 3D image, periodically transmitting a certain signal which does not include at least optical shutter control data. | ||

| 主权项 | 1. A wireless signal transmission device, comprising a wireless signal transmission section for, when an image display device displays a 3D image which is a three-dimensional image including a right-eye image and a left-eye image, transmitting, to 3D image glasses, (i) a first sync signal indicative of timing at which the right-eye image and the left-eye image included in the 3D image are switched and (ii) an optical shutter control signal for controlling optical shutters of the 3D image glasses which optical shutters alternately transmit and shut the right-eye image and the left-eye image, when the image display device displays an image other than a 3D image, the wireless signal transmission section periodically transmitting a certain signal which does not include the optical shutter control signal. | ||
