The method includes acquiring an image from an iris recognition camera in response to receiving a request for iris recognition, displaying a preview image including an iris recognition area corresponding to the iris recognition camera acquired from a regular camera in response to detecting an iris in the acquired image and obtaining information for the detected iris from the iris recognition camera and performing iris recognition using the information for the detected iris. ## Claims ### Claim 1 A method of recognizing an iris in an electronic apparatus, the method comprising: acquiring an image from an iris recognition camera in response to receiving a request for iris recognition; displaying a preview image including an iris recognition area corresponding to the iris recognition camera acquired from a regular camera in response to detecting an iris in the acquired image; and obtaining information for the detected iris from the iris recognition camera and performing iris recognition using the information for the detected iris. ### Claim 2 (depends on 1) The method of claim 1, further comprising displaying an iris guide in a preset location of the iris recognition area. ### Claim 3 (depends on 2) The method of claim 2, wherein the iris guide is located in a middle area of the iris recognition camera, and is a reference which informs a user about a location of the iris image. ### Claim 4 (depends on 3) The method of claim 3, wherein the iris guide is displayed as at least one of an emoticon, an icon, and a dotted line so as to be different from an area excluding the iris guide. ### Claim 5 (depends on 1) The method of claim 1, wherein the preview image is an image which displays a whole or a part of user's face and the iris recognition area. ### Claim 6 (depends on 1) The method of claim 1, wherein the preview image is an image which is obtained and displayed by cutting the iris recognition area corresponding to the iris recognition camera. ### Claim 7 (depends on 1) The method of claim 1, wherein performing iris recognition comprises: determining whether an iris image exists in the iris recognition area; obtaining the information for the detected iris from the iris recognition camera when the iris image exists in the iris recognition area; and providing a guide which indicates a direction to move the iris image into the iris recognition area, when the iris image does not exist in the iris recognition area. ### Claim 8 (depends on 1) The method of claim 1, wherein an accuracy for recognizing the iris in the iris recognition area is higher than an accuracy for recognizing the iris in an area excluding the iris recognition area. ### Claim 9 (depends on 7) The method of claim 7, wherein performing iris recognition further comprises: determining a location of the iris image, wherein determining a location of the iris image comprises performing at least one of: emitting light to a top of a frame, when the iris image is located above the iris recognition area; emitting light to a bottom of the frame, when the iris image is located below the iris recognition area; and emitting light to a middle of the frame, when the iris image is located to a left side or right side of the iris recognition area. ### Claim 10 An apparatus for recognizing an iris, the apparatus comprising: an iris recognition camera, which includes an infrared light emitting diode, configured to obtain an iris image; a regular camera configured to display a preview image; and a controller configured to acquire an image from the iris recognition camera in response to receiving a request for iris recognition, display the preview image including an iris recognition area corresponding to the iris recognition camera acquired from the regular camera in response to detecting an iris in the acquired image, and obtain information for the detected iris from the iris recognition camera and perform iris recognition using the information for the detected iris. ### Claim 11 (depends on 10) The apparatus of claim 10, wherein the regular camera is a camera which shares at least a portion of an angle of view of the iris recognition camera. ### Claim 12 (depends on 10) The apparatus of claim 10, wherein the iris recognition camera includes an image sensor configured to perform the iris recognition. ### Claim 13 (depends on 12) The apparatus of claim 12, wherein the infrared light emitting diode emits an infrared signal of a specific frequency band, and wherein the image sensor converts the infrared signal of the specific frequency band, which is emitted by the infrared light emitting diode and is reflected and is entered via a band pass filter, into a digital signal. ### Claim 14 (depends on 10) The apparatus of claim 10, wherein the controller displays the iris recognition area including the iris image corresponding to a physical distance between the iris recognition camera and the regular camera. ### Claim 15 (depends on 14) The apparatus of claim 14, wherein the controller determines a location of the iris image, and emits light to a top of a frame when the iris image is located above the iris recognition area, emits light to a bottom of the frame when the iris image is located below the iris recognition area, and emits light to a middle of the frame when the iris image is located to a left side or right side of the iris recognition area. ### Claim 16 An electronic apparatus comprising: an iris recognition camera, which includes an infrared light emitting diode, configured to obtain iris image information; a regular camera configured to display a preview image, and obtain an eye image; and a controller configured to display the preview image acquired from the regular camera in response to receiving a request for iris recognition, perform face recognition, obtain an eye area from the preview image and display the obtained eye area as an iris recognition area when information of a user corresponding to recognized face information exists among user face information stored in the electronic apparatus, and obtain information for a detected iris from the iris recognition camera in response to detecting an iris in the iris recognition area and perform iris recognition using the information for the detected iris.
