System and an ADPCM (adaptive differential PCM coding) type coder / decoder. The reproduction unit 15 includes the audio processing unit 1
The receiving signal from the speaker 4 is emitted from the receiving speaker 22.

[0007] The camera 16 captures an image of a medium or the like on which a telephone number is written, converts the captured result into image information, and outputs the image information to the image storage unit 20 and the display unit 18. Also, the camera 16
Can be rotated 180 degrees in the left-right direction as shown in FIG. The image storage unit 20 temporarily stores image information output from the camera 16. The display unit 18 displays image information output from the camera 16 or image information stored in the image storage unit 20. Further, the display unit 18 displays a menu corresponding to a telephone function or a button corresponding to operation of a numeric keypad or a jog dial.

The input section 17 is an input means comprising a numeric keypad consisting of numerical keys “0” to “9” and a code key, a jog dial, and the like provided on the mobile phone 1. When a predetermined key of the input unit 17 is operated, the pointer 23 displayed on the display unit 18 moves (FIG. 2).
The pointer 23 moves in the display unit 18 according to an input from the input unit 17. Further, when a predetermined key of the input unit 17 is operated, image information such as a telephone number displayed on the display unit 18 is selected. The telephone number recognizing unit 19 converts image information in the area selected by the pointer 23 into character information.

The ROM 12 stores programs such as various telephone function programs for transmission and reception executed by the CPU 10, processing for assisting audio reproduction processing, and various data. The RAM 11 stores character information output from the telephone number recognition unit. Further, the RAM 11 stores the system CP
A work area or the like of U10 is set. Each functional block transmits and receives data and instructions via the bus 24.

Next, the operation of the apparatus having the above-described configuration will be described with reference to FIGS.
