Description

  The present invention relates to an information processing terminal device, a control method for an information processing terminal device, and a program capable of assigning a predetermined function assigned in advance to a predetermined key to another key desired by the user.

  At present, mobile phones with camera functions are becoming popular due to the development of multimedia in mobile phones. On the other hand, there is also a demand for thinner mobile phones, and mounting the camera in a key-side housing (a housing equipped with various operation keys (including operation buttons)) is advantageous for thinning. Many mobile phones in which a camera is mounted on a key-side housing have been developed (see, for example, Patent Document 1).

  However, when the camera is mounted on the key-side casing, as shown in FIG. 8, when the user takes a picture of the camera, the camera 1 is covered with the finger of the hand holding the key-side casing 8 of the mobile phone. Occurs. This is because the camera 1 is mounted near the hinge portion 9 as shown in FIG. 3 in the key-side casing 8, and the “OK” key (usually a predetermined key assigned to the shutter key as shown in FIG. 7). This is because the key “5” operated when determining the execution of the function is also arranged near the hinge portion 9. In order to avoid this problem, placing the camera near the center or near the microphone other than near the hinge increases the possibility of covering the camera with your hand. If it is placed near the microphone, it becomes difficult to perform key operations during a call or when using web contents.

  In order to solve the above-described problem, for example, a technique disclosed in Patent Documents 2 and 3 which are prior art examples is used, and a preset shutter key is replaced with another key (a plurality of keys ( For example, it may be possible to change the key to a key that is easy for the user to press, but in this case, the user may forget which key the key is changed to after changing the shutter key to a desired key.

In the above description, the camera shutter key has been described as an example. However, in addition to the camera shutter key, a key that has a predetermined function set (assigned) in advance by default is assigned to another desired key. There is also a desire to change. Even in such a case, there is a possibility that the user may forget which key is changed after changing to a desired key.
