<P>PROBLEM TO BE SOLVED: To provide an information terminal device for improving convenience. <P>SOLUTION: The information terminal device switches into a blood vessel imaging mode among the blood vessel imaging mode imaging a blood vessel and an object imaging mode imaging the object other than the blood vessel, radiates the near infrared beams, and collates the information to be compared with the vessel to be imaged by means of the imaging element 14c, in response to that a slide plate 31, which movably holds a polarization plate 27 having polarization axes in a direction perpendicular to a direction of radiation in which near infrared beams are radiated, is moved and to that the polarization plate 27 is arranged on a light path of an imaging element 14c. <P>COPYRIGHT: (C)2011,JPO&INPIT |
