Abstract

An image displaying system comprises a display device and a remote control unit. The remote control unit is provided with a light emitting pointer device and a detector for detecting light emanating from the display device. The pointer device and the detector have corresponding lines of sight. The remote control unit further comprises a circuit for switching on and off the pointer device in dependence on an output signal of the detector indicating the receipt of light emanating from the display device. The pointer device is switched on if said output signal indicates the receipt of light and is switched off if said output signal indicates that no light is received.
