It is to provide a stereoscopic image transmission device that can be used for such operations.

[0009]

In order to achieve the first object, a method for transmitting stereoscopic video according to the present invention is to switch left and right digital video signals output by a left-eye camera and a right-eye camera to a transmission side frame. The frame is cut by the means and the frames are alternately transmitted by the transmitting means on the line in one frequency band, the digital video signal transmitted by the transmitting means is received by the receiving means, and the left receiving side frame switching means Then, while separating the frame of the video signal of the left-eye camera from the digital video signal received by the receiving means, the right receiving-side frame switching means changes the frame of the digital video signal of the right-eye camera from the digital video signal received by the receiving means. It is characterized in that the frames of the video signal are separated.

In order to achieve the second object, a stereoscopic image transmission apparatus according to the present invention is a left eye camera and a right eye camera, and digital image signals output by the left eye camera and the right eye camera. To a frame on a transmission side for alternately outputting this frame, a transmission means for placing the frame output from the transmission side frame switching means on a line in one frequency band, and a digital video signal Receiving means for receiving, left receiving side frame switching means for separating the frame of the video signal of the left eye camera from the digital video signal received by the receiving means, and the right eye camera from the digital video signal received by the receiving means And a receiving side frame switching means on the right side for separating frames of the video signal.

[0011]

The left and right digital video signals output by the left-eye camera and the right-eye camera are cut in frame units by the transmission-side frame switching means, and the frames are alternately transmitted by the transmission means on one line on one line. , The left receiving side frame switching means separates the frame of the video signal of the left eye camera from the digital video signal received by the receiving means, and the right receiving side frame switching means separates the digital image received by the receiving means. The frame of the video signal of the right-eye camera can be separated from the signal, and the stereoscopic image of a moving image of a remote place can be easily transmitted, which can be used for work monitoring, operation of a remote control robot, and the like.
