Abstract

PURPOSE:To allow the driver to major in the driving while enjoying a television picture properly without taking such care about the television picture by displaying a still picture on a display section while switching the picture for each prescribed time when a vehicle is driven. CONSTITUTION:When the driving mode is detected by a vehicle-speed sensor 13 or a parking brake signal, a means 4 generating a still picture signal is operated and a still picture rewritten for each prescribed time is displayed on a display device 7. On the other hand, when the vehicle is discriminated in the halt state, a dynamic signal of a received picture signal is sent and displayed onto the display device 7. Since the driver watches a still picture during driving, it is possible to major in the driving and safe driving is attained.
