Abstract
An objective of the present invention is to provide a portable information terminal device capable of reducing excessive time and labor required in an authentication process. A sub-camera is started on the basis of operation to select “secret mode” by a user (FIG. 9(a)) and brought into a photographable state after completion of an initialization process, which is followed by automatically performing an authentication process (FIG. 9(b)). Therefore, it is possible to prevent troublesome photographing operation by waiting for a time course from the start of the sub-camera to reaching a photographable state, allowing reduction of excessive time and labor required in an authentication process. Moreover, a time lag generated in a period from user confirmation of a photographable state after starting the sub-camera to performing photographing operation can be reduced, where the authentication process can be carried out in a shorter period of time after starting the sub-camera, so that an amount of time required in the authentication process can be shortened.
