If the displayed image data is image data stored in the storage unit 160, the playback of the image is simply stopped (see FIG. 8 (b)). Then, in order to allow the user to see a portion that is hard to see during the rotation operation, the control unit 180 continuously reproduces the received image data while reproducing the still image 7 (c)). According to this embodiment, even if the user rotates the mobile communication terminal 100, the image data that may be missed during rotation can be checked later. Although the operation according to the rotation detection signal has been described in the present embodiment, the present invention is not limited to this.

The above-described method of displaying an item and the mobile communication terminal to which the method and the method are applied are not limited to the configuration and method of the embodiments described above, but the embodiments may be applied to all or some of the embodiments May be selectively combined.
