Abstract

PURPOSE:To display a telephone directory automatically onto a monitor section in the case of hook-off by detecting the off-hook state by a state change detector, expanding a font data onto a picture memory 3 with a memory control circuit and applying the data to a monitor television receiver 7. CONSTITUTION:When a state change detector 13 detects the hook-off state, drive power supply is supplied to a camera section 1 and a monitor television receiver 7 being a monitor section. Simultaneously, a memory control circuit 11 reads a required telephone directory data from a telephone directory data storage memory 10, gives the data to a font data converter 9 and converts the telephone directory data into a font data. Then based on the control of the memory control circuit 4, the font data is expanded in the picture memory 3 and its state is displayed on the monitor television receiver 7. Thus, the telephone directory is displayed.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a television telephone that can display a telephone directory on a monitor television when off-hook. It is equipped with a camera section for capturing images, a memory section for storing image data, a monitor section (monitor television) for displaying images, a modem section for transmitting and receiving image data, and the like.

In recent years, such videophone devices have been equipped with memory means for storing telephone directory data, and by displaying the telephone directory on the monitor and specifying the displayed telephone number, it is possible to connect to the telephone line with the other party. A video telephone device in which processing is performed has been developed.

[Problems to be Solved by the Invention] In a videophone device having such a telephone directory display function, in order to display the telephone directory, a special key is provided on the keyboard, and a special key is provided on the keyboard, and the key is pressed. It is detected and the phone book is displayed.

Therefore, when attempting to make a call using the telephone directory, a two-step operation of going off-hook and pressing a key to display the telephone directory is required.

Therefore, the telephone directory cannot be displayed quickly.

Therefore, the present invention takes these points into consideration, and provides a videophone device that detects a change in the state of the hook switch and automatically displays the telephone directory on the monitor when the hook switch goes off-hook. This is what we propose.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention provides an image memory means for storing image data, and a telephone directory for storing telephone directory data such as names and telephone numbers. It has a data memory means, a conversion means for converting telephone directory data into font data for displaying, a means for detecting a change in the state of a hook switch, and an incoming call detection means, and displays the telephone directory on a monitor television when off-hook. It is characterized by the fact that it is made to do so.

"Operation" When there is no incoming call from the telephone line side, hook switch 1
2 is completely turned off, this is detected by the state change detector 13.

When an incoming call is not detected and an off-hook state is detected, driving power is supplied to the camera section 1 and the monitor television 7, which is a monitor section. At the same time, the memory side valve circuit 11 is fully controlled, and necessary telephone directory data is read out from the telephone directory data storage memory 10 and supplied to the font data converter 9, and the telephone directory data is converted into font data.

Thereafter, the font data is developed on the image memory 3 based on the data stored in the memory 1IillaII@Route 4, and its state is displayed on the monitor television 7. As a result, a telephone directory as shown in FIG. 3 is displayed.

Therefore, as soon as the user picks up the receiver and goes off-hook, the necessary telephone directory will be displayed on the monitor television 7. The user can call the other party's phone using the telephone number displayed in this telephone directory.

[Example] Next, an example of the videophone device according to the present invention will be described in the first example.
This will be explained in detail with reference to the figures below.

In the video telephone device shown in FIG. 1, an analog image signal captured by a camera section 1 is converted into a digital signal by an A/D converter 2 and stored in an image memory 3.

The image signal stored in the image memory 3 is subjected to D/A conversion N6
This is converted into an analog signal by the monitor TV 7.
The necessary images can be displayed.

Therefore, when transmitting the image (No. 3), the selector 16 is switched to the modem 5 side, and at this time the image signal stored in the image memory 3 is modified by the modem 5 and sent to the telephone line side.

Further, when receiving image data, the selector 16 is switched to the modem 5@ again. The image signal sent via the telephone line is @-adjusted by the modem 5 and stored in the image memory 3.

Thereafter, this image signal is supplied to the monitor television 7 via the D/A converter 6, so that the image of the other party is displayed.

Since the video telephone device is normally in an automatic reception state, the selector 16 is in the switching state shown. When an incoming call is received from the telephone line in this state, the incoming call detection formula 14 detects this state and sends an incoming call detection signal (No. 3) to the CPU 8 which functions as a control section.

As a result, power is supplied to the monitor television 7, and by raising the transmitter/receiver mode (not shown), the hook switch 12 becomes off-hook, and this state is detected by the hook switch state change detector 13 and the CPU 8 supplied to

When receiving an image, the CPU 8 instructs the selector 16 to switch to the modem 5 side, and the image signal received from the telephone line is displayed on the monitor television 7 as described above. 15 indicates a transmitting/receiving circuit.

In addition to these configurations, the present invention is provided with a storage memory 10 that stores telephone directory data such as names and telephone numbers.

Necessary telephone directory data can be read from the storage memory 10 under the control of the memory control circuit 11, and this data is supplied to the font data converter 9 and converted into font data.

The converted font data is developed on the image memory 3 under the control of the memory control circuit 4.

The image signal developed on the image memory 3 is converted into an analog signal by the D/A converter 6, and then supplied to the monitor television 7, so that the contents of the telephone directory data can be displayed.

FIG. 3 shows an example of the telephone directory display data.

By the way, such a telephone directory data display mode is a mode that is first executed when the incoming call detection N14 is not detecting an incoming call and the hook switch 12 is off-hook. Therefore, when the hook switch state change detection W13 detects the off-hook state, the state change signal is supplied to the CPU 8, and the camera unit 1 and the monitor television 7 are powered on.

After such a series of processes, the above-mentioned telephone directory data will be displayed on the monitor television 7.

Therefore, when the incoming call detector 14 detects an incoming call and goes off-hook, the camera section 1 and the monitor television 7 are powered on, but the telephone directory display process is not performed.

In this case, the memory control circuit 11 is controlled to be in an inactive state based on a command from the CPU 8.

FIG. 2 is an example of a processing flow for realizing the above-mentioned telephone directory display mode, in which off-hook is detected,
The power is turned on to the camera unit 1 and the monitor TV 7 only when the camera unit 1 and the monitor TV 7 are not being detected.
23) After that, according to the process described above, the telephone directory data can be displayed on the monitor TV (step 24).
.

On the other hand, when off-hook occurs during arrival ε, the normal reception mode is in effect, and in this case only the process of turning on the power to the camera unit 1 and monitor television 7 is executed (step 22. 25).

[Effects of the Invention] As explained above, according to the present invention, just by going off-hook to make a call, the necessary telephone directory data will be displayed on the TV monitor, allowing smooth dialing. It has the characteristic of being able to perform processing.
