Abstract: PURPOSE: A warning device of the separation of a vehicle from a lane is provided to prevent accident by tracing a lane promptly and warning of the degree of separation from a lane. CONSTITUTION: A lane or an obstacle on a road is imaged by an image input unit(10) and inputted to an amplifying/filtering unit(12). The amplifying/filtering unit amplifies the image signal to certain level and removes the element of noise in the image signal. Then, the image signals are transmitted to a synchronous division unit(14) and an A/D(analog/digital) conversion unit(16). The synchronous division unit divides a field signal and a vertical/horizontal synchronous signal needed for the pretreatment of the image signals from the image signals and supplies the divided signal to a pretreatment unit(18). The A/D conversion unit converts the analog video signal to digital signal by quantization and supplies the digital signal to the pre-treatment unit. A post-treatment unit(24) warns a driver of the separation of a lane via a buzzer or a blinking unit and controls an OSD(on-screen display) generation unit(28). The OSD generation unit outputs an OSD character message to an image output unit(36). If a vehicle is separated from a lane much, the buzzer sound is generated frequently and the blinking of the blinking unit becomes fast.
