Abstract
The present relates to an eye position display housed in an iris recognition system and a method thereof. Particularly, the iris recognition system comprises: a board (PCB) including a controller for controlling emission of light; a light emitter with a LED mounted on the PCB for emitting a light and uniformly scattering and equalizing the intensity of the emitted light; a lens unit for maintaining a focal length of the emitted light from the light emitter, refracting and converging the light at a constant angle, and passing the light through a predetermined portion only so as to display a position where a user's eye is should be; and a reflector unit for reflecting every wavelength band that passed through the lens unit except for a wavelength of a predetermined light.
Claims16
An iris recognition system, comprising:
- a board including a controller for controlling emission of light;
- a light emitter mounted on the board for emitting a light and uniformly scattering and equalizing the intensity of the emitted light;
- a lens unit for maintaining a focal length of the emitted light from the light emitter, refracting and converging the light at a constant angle, and passing the light through a predetermined portion only so as to display a position where a user's eye is should be;
- and
- a reflector unit for reflecting every wavelength band that passed through the lens unit except for a wavelength of a predetermined light.
A method of recognizing an iris, comprising:
- (1) pluralizing a distance between a user and an iris recognition system;
- (2) if the user approaches the iris recognition system, emitting a light from at least one light emitter, and passing the light through a diffuser and a mask;
- (3) allowing the user to see the refracted light from the lens;
- (4) showing various instruction patterns in accordance with a view angle of the user toward a reflector unit or a distance between the user and the iris recognition system;
- and
- (5) adjusting the distance from the user to the iris recognition system following the instructions manifested on the refractor unit.
