First Claim
1. An access control system in an automobile, comprising:
- a grayscale camera, configured to capture a grayscale image of the face of a driver;
an infrared camera, configured to capture an infrared image of the face of said driver simultaneously with said grayscale camera; and
a processing device, coupled to said grayscale camera and said infrared camera, comprising;
a processor, configured to receive the grayscale image captured by the grayscale camera and the infrared image captured by the infrared camera, convert the grayscale image and the infrared image to a grayscale matrix and an infrared matrix respectively, extract a feature matrix from the grayscale matrix and the infrared matrix, and compute a similarity value by comparing the feature matrix with a plurality of feature matrices representing facial information of authorized drivers to derive a result of face recognition; and
a controller, configured to receive the result of face recognition and control a startup device and a warning device of the automobile according to the result of face recognition.

Abstract
An access control system in an automobile is provided. The access control system includes a grayscale camera, an infrared camera and a processing device. The grayscale camera is configured to capture a grayscale image of the face of a driver. The infrared camera is configured to capture an infrared image of the face of the driver simultaneously with the grayscale camera. The processing device includes a processor and a controller. The processor is configured to receive the grayscale image and the infrared image, convert the grayscale image and the infrared image to a grayscale matrix and an infrared matrix respectively, extract a feature matrix from the grayscale matrix and the infrared matrix, and compute a similarity value by comparing the feature matrix with multiple feature matrices. The controller is configured to receive a result of face recognition and control a startup device and a warning device of the automobile.
