説明

We have developed a system called the Q stereoscopic video system which has high resolution in a wide angle image. This system enables us to achieve higher operational efficiency than a conventional stereoscopic video system. However, this system requires four video channels to transmit video signals. Because there is a limitation problem on the number of wireless transmission channels, four wireless channels are not always available for the video system. Therefore, we tried to reduce the number of channels used by this system by sending images from the right and left camera alternately by field. In experiment 1, we compared the Q stereoscopic video system with two channel transmission to the original Q stereoscopic video system. The result showed that the operators were able to work less efficiently under the Q stereoscopic video system with two channel transmission than under the original Q stereoscopic video system. In experiment 2, we developed the Q stereoscopic video system with three channel transmission. This system sent peripheral images from the right and left camera alternately by field via a single channel, as mentioned above. The result showed that the operational efficiency under the Q stereoscopic video system with three channel transmissions was equal to that under the original Q stereoscopic video system.
