摘要：
A dual purpose iris and color camera system is described provides good iris and color image capture in either IR or visible bands depending upon which type of image is being captured at that moment. For iris imaging the iris camera is capable of imaging in the 700 to 900 nm wavelength range where the iris structure becomes visible. The iris camera is able to perform iris imaging outside with full sunlight. The iris camera requires only a low level of cooperation from the user, in that they must be within a range of distances away from the iris camera, must hold relatively still for a short period of time, and must face towards the camera. The iris capture process is fully automated once activated.
