Input by selecting operations of characters, symbols, and buttons is image-input by handwriting on a digitizer input unit 3 of a transparent operation panel attached to a display surface of the video display unit 2 with a finger or an input pen. The image input is recognized by the OCR 15 and converted into text data. On the other hand, the button selection operation input is converted and input into predetermined selection data by the button input unit 18. These text data and selection data are added to the data memory 17 by adding month / day / time data, item number data, etc., which are automatically generated by the clock unit 34.

The appearance of the message sender and necessary video information are captured by the camera 4 and input as an analog video signal. The analog video signal is converted by the A / D 11 into a digital video signal. The digital video signal is converted and generated by the video data generation unit 12 into compressed video data such as JPEG or GIF. The video data is added to the video data memory 13 after adding correlation information with the data stored in the data memory 17 described above.

The message input by voice is input from the microphone 6 and converted into an analog voice signal. The analog audio signal is converted by the A / D 28 into a digital audio signal. The digital audio signal is decimated and compressed by the audio data generation unit 29, and is converted and generated into audio data. The audio data is added to the audio data memory 30 after adding correlation information with the data stored in the data memory.

The image generation unit 19 generates a display image signal based on the display format data stored in the display format memory 20 from the input video data, text data, selection data, and the like, and sends the display image signal to the video display unit 2. Output.
