JPH04200192A - Television telephone system provided with telephone directory display function - Google Patents

Abstract

PURPOSE:To utilize a telephone directory display function effectively by devising the telephone system such that a telephone directory data is displayed on a monitor television receiver only when an inputted password matches a registered password so as to register a private telephone number desired not to be known by other party by means of the password. CONSTITUTION:When a specific key such as a 'telephone directory' key 21 provided on a keyboard 16 is depressed, a CPU 18 controls a memory control circuit 12 to check whether or not a password on a 0 page of a telephone directory data is registered. When a password is registered, only the layout of a telephone directory is displayed but a name/telephone number is not displayed. When a numeral in 4 digits is entered in succession to a specific key such as a 'release' key provided on the keyboard 16, the entered 4-digit numeral is stored in an input password storage memory 13. The stored password is compared with a password on a 0 page of a registration password storage memory 11 by a password comparator 15 and when they match, the telephone directory data is displayed.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a video telephone device having a telephone directory display function.

(Summary of the Invention) The present invention includes a memory for storing a registered PIN and a memory for storing phonebook data, and only when the input PIN and the registered PIN match, the phonebook The present invention relates to a video telephone device that is configured to display data and allows the registration of a private telephone number that is not known to others.

(Prior Art) Generally, a videophone device includes a camera section for capturing images, a memory section for storing image data, a monitor TV section for displaying images, and a modem for transmitting and receiving image data. It has a department. A video telephone device is being considered which is characterized by adding a memory for storing telephone directory data such as names and telephone numbers, and displaying the telephone directory on a monitor (TV). However, with the videophone device having the phonebook display function as described above, when multiple people use one videophone device, it is difficult for anyone to display the phonebook data stored in the memory on the monitor TV. It was not possible to register private phone numbers as phone book data that other people might want to know.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the videophone device with a telephone directory display function of the present invention has a memory means for storing image data, a telephone directory display function for storing names, telephone numbers, etc. A memory means for storing the telephone directory data, a means for converting the telephone directory data into font data, a memory means for storing the registered password, and a memory means for storing the input password. If the entered PIN matches the registered PIN, the
When a PIN code is entered from the keyboard (dial keys), the entered PIN code is stored in memory. The stored PIN number is compared with registered PIN numbers. If they match, the telephone directory data is converted to font data, stored in the image memory, and displayed on the monitor television.

(Embodiment) Hereinafter, one embodiment of the videophone device with a telephone directory display function of the present invention will be described with reference to FIGS. 1 to 5.

FIG. 1 is a block diagram showing an embodiment of a video telephone device according to the present invention. FIG. 2 is a diagram showing an example of the data structure of telephone directory data, and FIG. 3 is a diagram showing an example of the data structure of registered password data.

In FIG. 1, an analog image signal (an image signal of a speaker) captured by a built-in camera unit 1 is converted into a digital signal by a 4-way/D converter 2, and is stored in an image memory 3. The image signal stored in the image memory 3 is modulated by the modem 5 and output to the telephone line. The image signal sent via the telephone line is sent to modem 5.
The n image is demodulated and stored in the image memory 3. The image signal stored in the image memory 3 is converted into an analog signal by a D/A converter 6, and output to a monitor television 7 for display. The image memory 3 is controlled by a memory control circuit 4.

Normally, it operates as described above, but certain keys provided on the keyboard 16, such as the "phonebook" key 21 (
(See FIG. 5) is pressed, the CP, U18 controls the memory control circuit 12 and checks whether the password on page 0 of the telephone directory data is registered.

If it is not registered, the CPU 18 controls the memory control circuit 10, and the telephone directory data stored in the telephone directory data storage memory 9 is transferred to the font data converter and converted into font data. After that, it is controlled by the memory control circuit 4 and stored in the image memory 8. The font data stored in the image memory 3 is converted into an analog image signal by a D/A converter 6 and displayed on a monitor television 7 (see FIG. 4).

If a PIN is registered, only the phone book layout will be displayed, but the name and phone number will not be displayed.

When a 4-digit number is entered following a specific key provided on the keyboard 16, such as the "release" key 27 (see FIG. 5), the entered 4-digit number is stored in the input password storage memory 13.・To be done. The stored password is compared with the password on page 0 of the registered password storage memory 11 by the password comparator 15, and if they match, the telephone directory data is displayed as described above.

Next, examples of dial operations that can be realized on the telephone directory display screen are shown below.

In addition to the dial keys, the keyboard 16 has a "phonebook" key 21 for displaying the telephone directory, as shown in FIG.
, "Previous page" key 2 for displaying the data of the previous page and next page
2. A "next page" key 23, an arrow key 24 for moving the cursor up and down, and a "determination" key 26 for performing a 25° dial operation are provided.

“Previous page” key 22. "Next page" key 23, arrow key 24.
By selecting the telephone light at 25 and pressing the "determination" key 26, dialing is performed.

When the "ENTER" key 26 is pressed, the CPU 18 switches the selector 17 to the telephone directory data storage memory 9 side and sends the telephone number indicated by the cursor to a dialer (not shown). After sending the telephone number, the selector 17 is returned to the keyboard 16 side.

In this state, when the dial key is pressed, the dial data is sent directly to the dialer, so it operates in the same way as a normal telephone.

(Effects of the Invention) As described above, the videophone device with a telephone directory display function of the present invention includes an image memory means for storing image data and a memory for storing telephone directory data such as names and telephone numbers. means, a font data conversion means for converting the telephone directory data into font data for displaying, a memory means for storing a registered password, and an input password and a stored password. The phonebook data is displayed on the monitor TV only when the input PIN number matches the registered PIN number, so it is not possible for others to know the PIN number. You can also register private phone numbers that you don't want, and you can effectively use the phone book display function.
