FACE DETECTION SYSTEM
First Claim
1. A face detection system for a vehicle, comprising:
- at least one first lighting unit for radiating infrared light onto a left side of a driver'"'"'s face;
at least one second lighting unit for radiating infrared light onto a right side of the driver'"'"'s facean image capturing unit for separately capturing the driver'"'"'s face onto which the infrared light is radiated from the first lighting unit or units and the second lighting unit or units; and
a control unit for acquiring left and right images of the face from the image capturing unit, and obtaining a difference image between the acquired left and right images, thus determining whether the driver is inattentive in looking ahead.

Abstract
The present invention relates to a face detection system for a vehicle. At least one first lighting unit is configured to radiate infrared light onto a left side of a driver'"'"'s face. At least one second lighting unit is configured to radiate infrared light onto a right side of the driver'"'"'s face. An image capturing unit separately captures the driver'"'"'s face onto which the infrared light is radiated from the first and second lighting units. A control unit acquires left and right images of the face from the image capturing unit, and obtains a difference image between the acquired left and right images, thus determining whether the driver is inattentive in looking ahead. The system stably performs the face detection function with no or less effect by external optical environments as well as reduced computational load.
