Abstract: The present invention generally relates to an iris recognition system, a method thereof, and more specifically, to an iris recognition system comprising the image selector scanning each iris image in pixel unit by using a mask defined into a second area which is in square shape and a first area configured as the peripheral girth of the second area, calculating the number of pixels C1 that luminance values of pixels located in the first area are smaller than a first threshold value and the number of pixels C2 that luminance values of pixels located in the second area are bigger than a second threshold value, and selecting an image of which the calculated pixel C2 values are minimum.

Abstract: The present invention generally relates to a photographing apparatus for iris authentication, a photographing module for iris authentication, and a terminal having the photographing apparatus for iris authentication, and the photographing apparatus for iris authentication in accordance with the present invention comprises: a body case whose front side is open; a camera module disposed inside the body case, generating an iris pattern image by photographing iris patterns while generating a general image by photographing a general object, and consisting of a housing, a lens module moving in front/rear directions, and a pickup device for converting an image incident through the lens module into an electric signal; a band pass filter disposed in front of the camera module, and transmitting 400 to 1000 nm wavelength beams in more than 50%, among beams incident on the lens module; and an LED lamp disposed around a front side of the camera module, and irradiating infrared wavelength beams forward.
