Abstract

PURPOSE:To obtain an inexpensive telephone directory function with ease of use by providing a telephone directory input means and a telephone directory memory and controlling the telephone directory memory with an image control processor. CONSTITUTION:The user uses a telephone directory input means 13 in the video memory display state 21 to start (22) the telephone directory function and to bring the state into the telephone directory memory display state 23. Then the telephone directory input means 13 inputs the telephone directory information. An image control processor 7 combines the telephone directory information received from a CPU 10 into a video image, writes it into the telephone directory memory 12 to revise the content of the telephone directory memory. Moreover, the image control processor 7 always reads the telephone directory memory and the telephone directory information is displayed on a monitoring television of a video I/O 9. Thus, the still picture video telephone set having the telephone directory function is obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a video telephone that transmits and receives audio and video.

[Conventional technology]

Figure 3 shows a block diagram of a simple still image telephone (published in Foreign Communication Technology, October 1986). Detection, detection of transmitted and received video signals 1 Detection of incoming calls, 2-4 line conversion, Lugio/off of telephone line (1),
Telephone unit interface for monitoring the telephone line (1), (3) is a matrix for switching between audio and video signals, sir channel, (4) is an analog circuit for amplifying and filtering audio signals, (5) (6) is a video compatible modem that modulates and demodulates video signals into audio band analog signals, (7) is an image control processor that processes video signals, and (8) is a video storage device. Video memo to do! J, (91 is a video system consisting of a camera, monitor TV, etc. that inputs and outputs video, αQ is a CPH that controls the entire system, and αη is a keypad such as a dial button, hook switch, video output button, etc.).

Next, the operation of the above telephone will be explained.

When an incoming call is received through the telephone line (1), the user responds by pressing the hook switch on the keypad αυ and selects CP[1rQ
(I controls the telephone unit interface (2), and when the telephone line (RI) is looped on, it becomes a talking state.

Usually, the matrix switch (3) connects the telephone interface (2) and the analog circuit (4).

Voice communication is possible through voice I10 (51).

In this case, if a video signal is included in the received signal, the telephone unit interface (2) detects this video signal and notifies cpaa* that the video signal has arrived. Then, 0PUQI controls the matrix switch (3) and connects the telephone interface (2) to the analog circuit (4).
) and connect a video compatible modem (6) in its place. Therefore, the video signal portion of the received signal is sent to the video compatible modem (6), which demodulates the analog video signal into a digital video signal, and the digital video signal is used for image control. Processor (7
) is written to the video memory (8), and the image control processor (7) also writes the video memo (January 8).
The content will be displayed on the video engineer 10 (91). Note that voice calls will not be possible during this time.

If you want to send your own video to the other party, use the video send button on the keypad U to command CPUQI to send video.
As in the case of video signal reception, pσα controls the matrix switch (3) to connect the mobile phone interface (2) and the video compatible modem (6). at the same time,
The CPUQI controls the image control processor (7) to store the video signal input from the video I10 f91 in the video memory (8) and send this video signal to the video compatible modem (6). Therefore, the own video signal is sent to the telephone interface (2) through the telephone line (
1) and sent to the other party.

Note that voice calls cannot be made during this time, as described above.

[Problem to be solved by the invention]

Since the conventional still picture video telephone is configured as described above, there is a problem in that the memory is used only for sending and receiving images, and it does not have a telephone directory function.

This invention has been made to solve the above-mentioned problems, and its object is to provide a still picture video telephone having a telephone directory function.

[Means to solve the problem]

The still picture television one-speech device according to the present invention is provided with a telephone directory memory in addition to a video memory, and is also equipped with a telephone directory input means.

[Effect]

The still picture video telephone according to the present invention realizes a telephone directory function by storing information inputted by the telephone directory input means in a telephone directory memory.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. 1st
In the figure, (1) to Qη are the same as in the conventional example. Alpha is a telephone directory memory that is controlled by the image control processor (7) as well as the video memory (8).

Store phone book information. αl starts the phone book function.

This is a telephone directory input means for inputting information to be stored in the telephone directory memory α. FIG. 2 is a flowchart showing the flow of operations.

Next, the operation will be explained. The transmission and reception of video is the same as in the conventional example, so it will be omitted.

In the video memory display state CAN, the user activates the SIMI word root function (2) on the telephone directory input means (1 book) to set the telephone directory memory display state (2).
1 For example, 9 Enter telephone directory information such as name and phone number (c). cpUtto passes this telephone directory information to the receiving image control processor (7). Image control processor (7) is (3Pσ0(
The receiver assembles the telephone directory information taken from I into an image in the form of a table, for example, and writes it into the telephone directory memo +7 a3 to change the contents of the telephone directory memory (to). In addition, the image control processor (7) constantly reads out the telephone directory memory 1, and the telephone directory information in the form of a table, for example, is displayed as an image on the monitor television of the video engineer 10 (9) (2).
). Therefore, while viewing the image of the telephone directory information displayed on the image x10 f91, the user can:

A telephone directory can be created using the telephone directory input means 0. Furthermore, if necessary, it is also possible to transmit and receive images of this telephone directory information in the same manner as in the past. The telephone directory function is terminated by the telephone directory input means αJ and c! 4. Return to video memory display state.

〔Effect of the invention〕

As described above, according to the present invention, the telephone directory input means and
Since a telephone directory memory is provided and the telephone directory memory can be controlled by an image control processor, an inexpensive and easy-to-use telephone directory function can be obtained.

[Brief explanation of the drawing]

FIG. 1 is a configuration block diagram showing a still image video telephone according to an embodiment of the present invention, FIG. 2 is a flowchart showing the flow of its operation, and FIG. 3 is a configuration block diagram showing a conventional still image video telephone.
