[Detailed description of the invention]

0001

[Industrial Field of Application] The present invention relates to a video signal transmitting means for capturing an image of a user by an imaging unit and transmitting the video signal to the other party through a telephone line; It relates to a telephone with an image display function that is equipped with a video signal receiving means that receives a video signal and displays it on a display unit, and more specifically, an image that allows selection of an initial image to be sent to a telephone line at the start of communication. Regarding a telephone with a display function.

0002

[Prior Art] Currently standardized still image video telephones for analog lines transmit an image of the user of the telephone to the other party when making a call or receiving a call. The image of the user who answers the phone is captured by a built-in camera, and the video signal is automatically sent to the other party.

[0003]Furthermore, even in still image video telephones for digital lines, the image of the user when answering the call is basically the same as the above-mentioned still image video telephones for analog lines, unless there is a special operation. It is designed to be sent to the side.

0004

[Problems to be Solved by the Invention] As described above, still image videophones are expected to have the advantage of being able to send image information of the user who answered the call (or made the call) at that time. On the other hand, the video may be sent to the other party inadvertently, so for example, if a still image videophone is installed in a highly confidential location, the confidential information may be sent to the other party as a video. Furthermore, if the system is installed in a private home, there is a problem that video related to that individual's privacy may be sent to the other party.

[0005] The present invention has been made in view of the above circumstances, and its purpose is to provide a telephone with an image display function that prevents the inadvertent transmission of images by making it possible to select the initial image to be sent to the other party. It is about providing.

[0006]

[Means for Solving the Problems] In order to solve the above-mentioned problems, the telephone with an image display function of the present invention is provided with a telephone that stores in advance a video signal from the imaging section as a video signal to be transmitted to the other party through a telephone line. a second storage means for storing a video signal of the other party as a video signal to be transmitted to the other party through a telephone line; a video signal stored in the first storage means; The apparatus is configured to include a selection means for selecting either one of the video signal stored in the storage means or the video signal imaged by the imaging section and transmitting the selected one to the telephone line.

[0007]

[Operation] The selection means is operated to set the video signal stored in the storage means to be sent to the other party through the telephone line. Here, the storage means normally stores the user's own image in advance, but in addition to this, it is also possible to store a video signal of the user of the other party's telephone that is sent from the other party when a call is received. It's okay. As a result, when making a call, instead of using the video signal of the user at that time captured by the imaging unit,
It becomes possible to send the user's video signal stored in advance in the storage means to the other party through the telephone line. Furthermore, when a call is received, instead of the image signal of the user at that time captured by the imaging unit, the image signal of the user stored in advance in the storage means or the image of the user of the other party's telephone sent through the telephone line is used. It becomes possible to send the signal to the other party through the telephone line. The first storage means for storing the video signal of the user of this telephone and the second storage means for storing the video signal of the user of the other party's telephone sent from the other party's telephone when a call is received are separated. In the case where the selection means selects and outputs either the video signal from the imaging unit or the video signal stored in the first storage means at the time of transmission,
When receiving a call, it is possible to select and output any one of the video signal from the imaging unit, the video signal stored in the first storage means, or the video signal stored in the second storage means. Become.

[0008] In this manner, by transmitting the video signal stored in the first storage means when making a call and when receiving a call, both the sender and the receiver can communicate with peace of mind. Also,
By temporarily storing the received image in the second storage means and sending it back when a call is received, it is possible to notify the user of the other party's telephone that the line has been connected, and
You can also check what kind of image was sent to the other party.

Further, the video signal of the other party sent from the other party's telephone is transmitted to the video transmission/reception control unit 4 via the line interface 2.
Here, the signal is demodulated and temporarily stored in the reception memory section 10, and then outputted to the display section 11 to display a still image of the other party.

Next, the first to third changeover switches 15,
The operation when 16, 17 and setting switch 18 are arbitrarily set will be explained.

Now, the first to third changeover switches 15,
16 and 17 are all in the off state, and the setting switch 18 is set to the fixed contact a side. Further, it is assumed that the transmission memory section 14 has already stored the user's video signal to be transmitted.

In this state, when a calling signal is sent from the other party, this calling signal is detected by the incoming call detection circuit 5 via the line interface 2, and the incoming call detection signal is given to the switch control section 6. The switch control unit 6 switches the setting switch 18 based on this incoming call detection signal.
A switching control signal according to the settings is sent to the switching control input e of the switching circuit section 9, and the connection of the switching circuit section 9 is switched to either the fixed contact a or the fixed contact c. That is, when the setting switch 18 is connected to the fixed contact a side, the switching circuit section 9 also switches its connection to the fixed contact a side,
