METHOD AND DEVICE FOR IRRADIATING LIGHT FOR PHOTOGRAPHING IRIS |
| 摘要 |
A method and device for controlling an irradiating light for photographing an iris is provided. The device includes a light source configured to generate light, an active lens configured to adjust a refractive index of light passing through the active lens, an image capturer configured to capture an image of the iris by using a camera, and a controller configured to control the active lens to change the refractive index of the light passing through the active lens based on distance, motion and ambient light levels. |
