Problems solved by technology

However, if the current use environment is significantly different from the environment when the reference picture was captured, the performance of such a conventional face recognition system will be significantly reduced, and the user's real-time picture may not be matched with any reference picture in the reference picture database, resulting in Reduced recognition rate

Embodiment Construction

[0039] figure 2 Shown is a facial recognition system 200 in accordance with one embodiment of the invention. The face recognition system 200 includes a picture capture device (such as a camera 202 ) for capturing real-time pictures of the target (to be recognized) user's face. The face recognition system 200 further includes a reference picture database 204 and a comparator 206 . The reference picture database 204 stores one or more reference pictures. The comparator 206 is connected to the camera 202 , and the comparator 206 compares the real-time picture with one or more reference pictures to generate a feedback signal to the camera 202 . The comparator 206 adjusts one or more camera settings through the feedback signal, and further determines the adjustment direction of the camera settings.

[0040] The camera 202 captures the first real-time picture of the target user, and transmits the first real-time picture to the comparator 206 . In one embodiment, the comparator ...

Abstract

The present invention discloses a system and a method for optimizing the setting of picture catching device, and especially to an electronic system which can automatically optimizing the setting of camera and a method for optimizing the setting of camera. The electronic system comprises a storing device for storing reference picture, a picture catching device for catching the real-time picture of target object; and a comparator which is connected with the picture catching device for comparing the real-time picture and the reference picture and controlling the picture catching device according to a comparing result. Compared with the prior art, the system and the method according to the invention can reproduce the light state and color state of reference picture through automatically optimizing the setting of camera thereby increasing the matching success rate between real-time picture and reference picture.

Description

technical field [0001] The present invention relates to a picture capture device. Background technique [0002] The face recognition system is a system that automatically identifies users by matching real-time pictures of users with reference pictures. [0003] figure 1 Shown is a conventional facial recognition system 100 comprising a camera 102 , a reference picture database 104 and a comparator 106 . There are multiple comparison pictures stored in the reference picture database 104 . The camera 102 captures a real-time picture and transmits the real-time picture to the comparator 106 . The comparator 106 compares the real-time picture with the reference picture in the reference picture library 104 to generate a recognition result. The recognition result indicates whether the real-time picture can be matched with a reference picture. [0004] Such conventional face recognition systems can perform better if the current usage environment (such as lighting conditions an...
