Abstract

A car image recording system with auto shut-off function includes a sensing device. The sensing device senses an external impact, and after the impact time exceeds a predetermined time, the sensing device sends a stopping message to stop actions of the car image recording system. The sensing device includes a sensing switch and a timer. The sensing switch generates a strike message when sensing an external impact and sends the strike message to the timer. The timer generates a stopping message after having received the strike message for a predetermined time and sends the stopping message to the car image recording system for stopping the actions of the car image recording system.

Claims

1. A car image recording system with auto shut-off function, comprising:

a sensing device, which sends a stopping message to stop actions of the car image recording system after having sensed an external impact for a predetermined time.

2. The car image recording system with auto shut-off function as described in claim 1, further comprising:

a logic circuit connected to the sensing device, wherein the logic circuit makes the actions of the car image recording system stop after receiving the stopping message.

3. The car image recording system with auto shut-off function as described in claim 1, wherein the sensing device comprises a sensing switch and a timer, the sensing switch generates and sends a strike message to the timer after sensing an external impact, and the timer generates a stopping message after having received the strike message for a predetermined time for stopping the actions of the car image recording system.

4. The car image recording system with auto shut-off function as described in claim 3, further comprising:

a logic circuit connected to the timer, wherein after the logic circuit receives the stopping message, the logic circuit makes the actions of the car image recording system stop.

5. A car image recording system with auto shut-off function, which comprises a receiving device, an image digitizer, a scaler, an image compressor, a storage device, and a storage device controller, the car image recording system is characterized in that:

further comprises a sensing device, wherein the sensing device sends a stopping message after having sensed an external impact for a predetermined time for stopping actions of the car image recording system.

6. The car image recording system with auto shut-off function as described in claim 5, wherein the sensing device further comprises an external interface for connecting with external devices.

7. The car image recording system with auto shut-off function as described in claim 5, further comprising:

a logic circuit connected to the sensing device, wherein after the logic circuit receives the stopping message, the logic circuit makes the actions of the car image recording system stop.

8. The car image recording system with auto shut-off function as described in claim 5, wherein the sensing device comprises a sensing switch and a timer, the sensing switch generates and sends a strike message to the timer after sensing an external impact, and the timer generates a stopping message after having received the strike message for a predetermined time for stopping the actions of the car image recording system.

9. The car image recording system with auto shut-off function as described in claim 8, further comprising:

a logic circuit connected to the timer, the receiving device, the image digitizer, the scaler, the image compressor, the storage device, and the storage device controller, wherein the logic circuit receives the stopping message and sends the stopping message to the receiving device, the image digitizer, the scaler, the image compressor, the storage device, and the storage device controller for stopping the actions of the car image recording system.

10. A sensing device for being used in a car image recording system, comprising:

a sensing switch; and

a timer,

wherein the sensing switch generates a strike message after sensing an external impact and sends the strike message to the timer, and the timer generates a stopping message after having received the strike message for a predetermined time for stopping the actions of the car image recording system.
