Abstract
A finger vein recognition system includes an IR camera, a handle with a sensor and a IR LED array, and a microprocessor for controlling the LED array and processing image signals received from the camera. The luminescence of each LED in the LED array can be changed based on the position of a user's fingers and the environment, which improves the quality of images captured by the IR camera. The sensor detects the proximity of a user and activates the system.
