First Claim
Patent Images
1. A method of recording traffic images to be implemented in a drive recorder system, the method comprising:
- recording the traffic images at a first recording frame rate;
generating a detection signal according to movement of the vehicle;
searching a pre-stored table to acquire a vehicle driving condition matching with the detection signal; and
recording the traffic images at a second recording frame rate when the acquired vehicle driving condition corresponds to an alert condition, wherein the second recording frame rate is greater than the first recording frame rate.

Abstract
A method of recording traffic images is to be implemented in a drive recorder system. The method includes recording the traffic images at a first recording frame rate, generating a detection signal according to movement of the vehicle, searching a pre-stored table to acquire a vehicle driving condition matching with the detection signal, and recording the traffic images at a second recording frame rate when the acquired vehicle driving condition corresponds to an alert condition. The second recording frame rate is greater than the first recording frame rate.

9. A drive recorder system for use in a vehicle, comprising:
-
an image capturing unit configured to record traffic images at a first recording frame rate when the drive recorder system is switched from a deactivated state to an activated state; a motion sensing unit for generating a motion value according to movement of the vehicle; a storage unit for storing a pre-stored table that defines relationships between a plurality of detection signals and a plurality of vehicle driving conditions that respectively match with the detection signals; and a processing unit coupled electrically to said image capturing unit, said motion sensing unit, and said storage unit; said processing unit being configured to receive the motion value from said motion sensing unit, to perform motion detection computation upon the motion value to obtain a computed detection signal, to acquire, from the pre-stored table, one of said vehicle driving conditions that matches with the computed detection signal, and to activate the recording of the traffic images at a second recording frame rate when the acquired vehicle driving condition corresponds to an alert condition, wherein the second recording frame rate is greater than the first recording frame rate. - View Dependent Claims (10, 11)

12. A drive recorder system for use in a vehicle, comprising:
-
an image capturing unit configured to record traffic images at a first recording frame rate when the drive recorder system is switched from a deactivated state to an activated state; an antenna unit operable to receive a global positioning system (GPS) signal; a storage unit for storing a pre-stored table that defines relationships between a plurality of detection signals and a plurality of vehicle driving conditions that respectively match with the detection signals, said storage unit further storing map data; and a processing unit coupled electrically to said image capturing unit, said antenna unit, and said storage unit; said processing unit being configured to receive the GPS signal from said antenna unit, to perform a comparison computation upon the GPS signal and the map data stored in said storage unit to acquire a current position, to generate a detection signal when the current position is located on or adjacent to at least one road, to acquire, from said pre-stored table, one of said vehicle driving conditions that matches with the generated detection signal, and to activate the recording of the traffic images at a second recording frame rate when the acquired vehicle driving condition corresponds to an alert condition, wherein the second recording frame rate is greater than the first recording frame rate. - View Dependent Claims (13, 14)
