Abstract

PURPOSE:To enable a caller himself or herself to confirm a video-recorded image on a caller's-side image display device by switching a switch to the side of an image input device, and sending image data out of the image input device to a communication line an also inputting the data to the image display device. CONSTITUTION:When a control signal detecting device 11 detects a control signal sent through a separating device 6, the video telephone set 40 switches the switch 10 for inputting the image data to the image display device 8 to the side of the image input device 2. The image data for a message which is inputted from the image input device 2 of the video telephone set 40 is multiplexed by a multiplexing device 4 together with a message inputted from a voice input device 1 through a compressing device 3 and sent out to an automatic answering video telephone set 41. Further, the image data for the message is displayed on the image display device 8 when sent out, so the image data inputted from the image input device 2 is displayed on the image display device 8 of the video telephone set 40. Consequently, the caller can confirm the image video-recorded on the automatic answering telephone set 41.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention is applied to a videophone that makes a call to an answering videophone. In particular, the present invention relates to means for automatically controlling image display when making a call to an answering video telephone.

〔overview〕

The present invention provides a video telephone having a means for recording image data on the answering video telephone, by displaying the video data to be recorded on its own screen display in response to a command from the answering video telephone of the other party. This allows the caller to check the recorded images.

[Conventional technology]

Currently, answering machines have rapidly entered our daily lives and become a fixture. On the other hand, with the introduction of the ISDN network, videophones have been developed that allow a person to have a conversation while looking at the other person's face. Therefore, in the future, when a call arrives on a video phone set while you are away, a pre-recorded response image and response message will be sent to the caller, and after sending, the image and message from the caller will be recorded. It is expected that an answering video telephone equipped with an answering machine recording means will be developed. Once such an answering video phone was developed,
Unlike conventional answering machines, when recording an image and message from a caller, what to display on the caller's image display device becomes a serious problem from a man-machine perspective.

[Problems to be solved by the invention] With such conventional answering video telephones, nothing is displayed on the image display device of the caller when the caller records the message. The disadvantage is that the caller cannot check the recorded image.

The present invention consists of 1. It is an object of the present invention to provide a video telephone that eliminates such drawbacks and allows a caller to check the image recorded on an answering machine.

[Means for solving problems]

The present invention provides an audio input device that generates audio data, an image input device that generates original image data, and a compression device that compresses the original image data from the image input device to generate compressed image data. a multiplexing device that multiplexes the audio data from the audio input device and the compressed image data generated by the compression device; a separating device that separates the incoming multiplexed audio data and compressed image data; A decompression device that decompresses the compressed image data separated by the separation device to restore the original image data, an image display device that displays the original image data, and an audio output device that outputs the audio data from the separation device. A video telephone set includes a switch inserted into a path between the decompression device and the image display device to selectively connect the image display device to either the decompression device or the image input device; means for detecting a control signal arriving following a response message and response image data arriving from the calling answering video telephone; and when this means detects the control signal, issuing a command to connect the image display device to the image input device; and a control signal detection device having means.

Further, the separating device may include means for extracting the multiplexed control signal coming from the answering video telephone.

Function: When image data is recorded on the answering video telephone, this image data is given to the screen display device of the own telephone and displayed in response to a control signal from the answering video telephone. As a result, conventionally, if the provided image data is displayed incorrectly, confirmation becomes impossible, but with the present invention, the caller can reliably confirm the recorded image.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows the countries constituting the block showing this embodiment. In FIG. 1, the part that makes the present invention possible is a video telephone 40. The video telephone 40 includes an audio input device 1, an image input device 2, a compression device 3 that compresses image data from the image input device 2, a multiplexing device 4 that multiplexes audio data and image data, and a communication line. 5, a separating device 6 separates the image data and audio data received from the separating device 6, a decompressing device 7 decompressing the image data from the demultiplexing device 6, and an image display device 8 displaying the image data decompressed by the decompressing device 7. , an audio output device 9 for outputting audio data from the minute device 6, and a switch l for inputting image data from either the image input device 2 or the decompression device 7 to the image display device 8.
The control signal detection device 11 detects the control signal sent from the communication line 5 via the separation device 6. That is, this embodiment includes an audio input device 1 that generates audio data, an image input device 2 that generates original image data, and compressed image data by compressing the original image data from this image input device 2. a compression device 3 that generates the audio data from the audio input device 1 and the compressed image data generated by the compression device 3; a separation device 6 that separates the data; an expansion device 7 that expands the compressed image data separated by the separation device 6 to restore the original image data;
An image display device 8 that displays original image data and a separation device 6
In a video telephone equipped with an audio output device 9 for outputting audio data from a computer, the video telephone is further inserted into the path between the decompression device 7 and the image display device 8, and is inserted into the path between the decompression device 7 and the image display device 8 to display the image. A switch 10 for selectively connecting the device 8 to either the decompression device 7 or the image input device 2
