<P>PROBLEM TO BE SOLVED: To provide an object recognition system including a light source controller configured to control an illumination level of a light source in response to an ambient light level. <P>SOLUTION: The object recognition system 100 includes a camera 102 configured to capture an image of an object 112 illuminated by a light source 114. A computer 106 compares data representative of the image with stored image data. A method of illuminating an object in the object recognition system includes controlling the illumination level of the light source directed toward the object in response to the ambient light level. A method of controlling access of an object to a secure area includes the steps of: determining the ambient light level, setting the illumination level for the object in response to the ambient light level, illuminating the object at the illumination level, operating the camera to capture an image of at least a portion of the object, comparing the data representative of the image with the stored data, and allowing access of an object to a secure area in response to the comparing of the image with the stored image data. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
