Problems solved by technology

[0004] However, if the input image is captured under various ambient lights, shadows are cast on the face under direct sunlight, or the face itself becomes unclear in a dark room, making it difficult to display the features of the face on the input image
Therefore, there is a problem that the collation accuracy of the input image and the registered image decreases

Embodiment 1

[0075] In this Example 1, the details image 3 The illustrated lighting unit 10 is a face authentication device 1a using a single type of light source. First, use Figure 4 The configuration of this face authentication device 1a will be described. Figure 4 It is a block diagram showing the configuration of the face authentication device 1a of the first embodiment.

[0076] Such as Figure 4 As shown, the face authentication device 1 a includes a lighting unit 10 and a face authentication terminal 20 , the lighting unit 10 stores illuminance transformation information 11 , and includes a lighting control unit 12 and a halogen lamp 13 . In addition, an illuminance sensor 14 is connected to the lighting control unit 12 . Furthermore, the face authentication terminal 20 stores a face authentication algorithm 21 , and a camera 22 and a human body sensor 23 are connected to the face authentication terminal 20 .

[0077] The lighting unit 10 is corresponding to the image 3 Th...

Embodiment 2

[0102] Figure 7 It is a block diagram showing the configuration of the face authentication device 1b of the second embodiment. Such as Figure 7 As shown, the face authentication device 1b is the same as the face authentication device 1a of Embodiment 1 (refer to Figure 4 ) in that the two light sources of the halogen lamp 13 and the incandescent lamp 13 a are connected to the lighting control unit 12 . In addition, the information stored as the illuminance conversion information 11 is also different from that of the first embodiment. Here, use Figure 8 An example of the illuminance conversion information 11 of the second embodiment will be described.

[0103] Figure 8 It is a figure which shows an example of the illuminance conversion information of Example 2. As shown in the figure, the illuminance conversion information 11 of the second embodiment includes information to turn on the incandescent lamp 13a when the ambient illuminance is less than 5000, and turn on ...

Abstract

When an occupancy sensor detects an authentication object, a lighting unit obtains ambient light illumination measured through an illumination sensor, determines lighting illumination through used illumination changing information, namely the information of lighting illumination corresponding to ambient light illumination, so as to form low-level illumination on condition of low-level ambient light illumination and form high-level illumination on condition of high-level ambient light illumination, and controls illumination of a light source so as to radiate the determined illumination. Then a face authentication terminal authenticates the authentication object in a state of lighting by the lighting unit.

Description

technical field [0001] The present invention relates to a face authentication device, a face authentication method, and a face authentication program capable of performing identity verification by capturing the face of an authentication object as an input image and checking the captured input image with a registered image, and particularly relates to a face authentication program that can be used in various A face authentication device, a face authentication method, and a face authentication program that perform authentication with high accuracy under such ambient light without causing discomfort to an authentication subject. Background technique [0002] Conventionally, there is known a face authentication device that collates an input image of an authentication target's face captured by a CCD (Charge Coupled Device) camera or the like with a registered image registered in advance to authenticate the person. [0003] Such a face authentication device is installed outdoors w...
