A portable communication terminal with an iris recognition function is provided to take a picture of an iris image by using a single camera, thereby taking, storing, and reproducing a general image as conducting user registration and authentication based on iris recognition. A picture-taking device comprises as follows. A filter unit(31) is divided into an infrared transmission filter and an infrared blocking filter, and is equipped with a motor connector in a lower section. A motor(32) is driven by a particular key signal of a portable communication terminal(30), and has a lead screw shaft which moves the filter unit(31) to right/left directions as rotating in forward/reverse directions by being coupled with the motor connector. A camera(33) takes a picture of a user's iris through the infrared transmission filter, and takes a general image through the infrared blocking filter. A lamp(34) lights up infrared and visible rays simultaneously.
