Abstract: A portable terminal includes: an opening and closing portion that opens and closes; an open and close detecting unit that detects open and close of the opening and closing portion; a first processing unit that executes a first process while the open and close detecting unit is detecting that the opening and closing portion is open; and a second processing unit that executes a second process when the open and close detecting unit detects that the opening and closing portion has been closed, and the second process is a process with respect to an execution result of the first process.

Abstract: A cellular telephone including a function of a videophone is provided. During connection through a communication path, character data is combined with image data to obtain composite data. Thus, it is no longer necessary to transmit the character data through a different channel from the image data. Moreover, during connection of the communication path, the character data in the composite data relevant to the contents of the talk, for example, can be displayed on a display. Thus, the contents of the talk (information) can be quickly and accurately transmitted.

Abstract: A cellular telephone including a function of a so-called videophone continuously transmits image data obtained by forming an image with a camera together with voice data obtained by inputting a voice by use of a microphone. During connection of a communication unit through a communication path, a character composition circuit combines character data with the image data to obtain composite data. This composite data is transmitted by the communication unit during connection of the communication path. During connection of the communication path, the character data is combined with the image data to obtain the composite data. Thus, it is no longer necessary to transmit the character data through a different channel. Moreover, during connection of the communication path, the character data in the composite data relevant to the contents of the talk, for example, can be displayed on a display. Thus, the contents of the talk (information) can be quickly and accurately transmitted.
