A television for storing and displaying a stored still picture, which includes: a memory for storing a still picture of a desired scene; a decoder for separating a video signal of a broadcast channel into an RGB signal and a synchronizing signal; a synchronizing signal detector for outputting a detection signal according to the existence of the synchronizing signal; a microcomputer for controlling so that the RGB signal output from the decoder can be displayed on a picture tube by recognizing the detection signal when a normal broadcast signal is input and so that the still picture stored in the memory can be displayed on the picture tube when a normal broadcast signal is not input. Thus, if a broadcast channel goes off the air, or a channel which is not on the air is selected, a selected picture is retrieved from the memory and displayed on the television screen, thereby reducing eye fatigue. |
