The invention provides a vehicle-mounted machine system and method for quickly and stably displaying a reversing image. The vehicle-mounted machine system comprises a system-on-chip, a micro-control unit, a gear controller, a display screen, a video decoder and a reversing camera controller, and the micro-control unit is respectively connected with the system-on-chip and the gear controller, and is used for sending an acquired reversing trigger signal to the system-on-chip; the video decoder is connected with the reversing camera controller and is used for acquiring a reversing video signal from the reversing camera controller; the video decoder is connected with the system-on-chip and is used for notifying the system-on-chip that the reversing video signal is stable when the reversing video signal is stable and outputting the reversing video signal to the system-on-chip; and the system-on-chip is connected with the display screen and is used for outputting the stable reversing video signal to the display screen. According to the invention, the problem of unstable reversing video signals is solved.

    本发明提供一种实现快速且稳定出倒车影像的车机系统及方法,所述车机系统包括系统级芯片、微控制单元、档位控制器、显示屏、视频解码器和倒车摄像头控制器,其中微控制单元分别与系统级芯片和档位控制器连接,用于将获取的倒车触发信号发送到系统级芯片;视频解码器和倒车摄像头控制器连接,用于从倒车摄像头控制器获取倒车视频信号;视频解码器和系统级芯片连接,用于当倒车视频信号稳定时,通知系统级芯片所述倒车视频信号稳定,并向系统级芯片输出倒车视频信号;系统级芯片与显示屏连接,用于向所述显示屏输出稳定的倒车视频信号。通过本发明,解决了倒车视频信号不稳定的问题。
