Next, the continuous reproduction operation of the above-mentioned recorded message will be described with reference to the flowchart of FIG.

The start address of the image of each telephone call recorded in the image memory unit 9 is recorded in the internal memory of the image signal input / output control unit 13. When the image continuous reproduction key of the operation key group 17 is selected in step S301, the image signal input / output control unit sets the read start address of the first recorded message. Then, the process proceeds to step S302, the first image data is read from the image memory unit 9,
In step S303, the image data is displayed on the display unit 15. Then, when the display for one screen is completed in step S304, the process proceeds from step S305 to S306. If there is no next key input in step S306 and the screen is displayed for a predetermined number of seconds in step S305, the process proceeds to step S307, in which the read start address of the second recorded message is set, and then the image data is similarly read out and displayed. . Then, by repeating the above operation until the next key input operation is performed in step S306, it is possible to automatically and continuously display all of the recorded image data.

During the continuous display operation of the image data, if the selection key operation is input by the user in step S306 during the single screen display, the continuous operation is interrupted and the image selected in step S308 is displayed as it is. . Then, when the user inputs the voice output operation key, the image signal input / output control unit 13 outputs the selection control signal to the voice signal input / output control unit 13 in order to select the voice signal corresponding to the currently displayed image. Send to 14. Then, the audio signal input / output control unit 14 reads an audio signal corresponding to the image displayed according to the selection control signal from the audio memory unit 12 and outputs it from the speaker 18. By this series of operations, a message corresponding to the selected image can be automatically output.

Next, a multi-screen reproduction operation for collectively displaying a plurality of still screens recorded in the image memory unit 9 on one screen of the display unit 15 will be described with reference to the flowchart of FIG. 4 and the explanatory view of FIG.

This multi-screen display operation is an operation of dividing one screen of the display unit 15 into 16 pieces as shown in FIG. 5, reducing the absence images in each, and displaying 16 sheets collectively.

In the flowchart of FIG. 4, when the user selects the multi-screen playback key, the image signal input / output control unit 13 sets the read start address of the first recorded message at the same time as the continuous display operation in step S401. . Then, in step S402, the image data is read from the image memory unit 9. Next, in step S403, the image data is thinned to 1/4 in both the vertical and horizontal directions to reduce it to 1/16. The image reduced to 1/16 is displayed at the position shown in FIG. 5 in step S404 in accordance with the address signal controlled by the image signal input / output control unit 13. Then, in step S405, the first
When the display of the recorded message is completed, the flow advances from step S406 to step S407 to set the read start address of the second recorded message. The same operation as described below
The second recorded message image is displayed at the position shown in the figure. By repeating this series of operations until the 16th image is displayed at the position shown in FIG. 5, it is possible to collectively display 16 recorded messages on one screen of the display unit 15.

As described above, the still image is transmitted / received, the received image signal is accumulated, and the accumulated image is automatically and continuously reproduced, while the multi-screen display is performed. Therefore, the following effects are obtained.
