PURPOSE:To switch a monitoring screen in corresponding to the wearing and nonwearing of a pair of glasses by providing a transmission means to glasses, providing a reception control means to a television receiver or a video reproducing device and switching th type of image to be projected. CONSTITUTION:A switching signal generating means 1 to transmit a display mode switching signal and a second transmission means 8 to have a infrared lamp, which is flashed based on this display mode switching signal, are provided on the glasses C. Accordingly, when a user wears the glasses C toward a television receiver B, a second reception means 5 detects the output of this second transmission means 8 and a switching control means 4 switches a changing-over switch 7 to an S side based on the detected output. As a result, a stereoscopic video signal is inputted to an image monitoring means 6 as it is and a stereoscopic image is projected to a receiving surface. |
