1. A mobile terminal for iris recognition, comprising: a narrow-angle image collection unit within a camera for collecting a first image of a user's eye by using an infrared ray, wherein the first image includes an iris image and a specular image caused by a specular light reflected by a user's glasses; a wide-angle image collection unit within the camera for collecting a second image wider than the first image, by using a visible light; an image processing part recognizing by a processor a user's iris from a combination of the first image and the second image; a specular light search unit determining by the processor a location of the specular image from the first image; and a display unit displaying the second image including a positioner guiding a location of an eyeball to a user, based on the location of the specular image, when the specular image interferes with the iris recognition, wherein the specular light search unit searching a part of the image that has highest chromaticity on the first image and determining the searched part to be the location of the specular image, wherein the displayed positioner comprises an indicator directing a position of the user's eye to avoid overlapping with the specular image, and wherein the indicator does not direct the position of the user's eye if there is no specular light or if the specular light does not affect iris recognition.
