To efficiently perform work using a remote-controlled robot, an image display device that allows the operator to verify the working area from a single view is necessary. Furthermore, this device should provide high-resolution images of locations so that the operator can recognize depths in detail. To meet these requirements, conventional three-dimensional image devices used multiple cameras and display screens for the right and left eye. In this study, we developed a video device that employs a camera and a display, which records a wide range while providing high resolution for the central part of the images using a mirror. The effectiveness of our device was confirmed through an evaluation experiment using a remote-controlled work robot. The results indicated that using the transmitted complex display, the operator can utilize high-precision space information and respond to a wide range of changes in the surrounding environment. It was thus confirmed that the remote-controlled operation could be conducted with improved accuracy and in a shorter time.
