Abstract

PURPOSE:To synthesize plural still picture data and to select and output one of them by connecting an external monitor such as a home use television receiver to the telephone set so as to display simultaneously a moving picture and a still picture and providing a still picture data memory to the telephone set. CONSTITUTION:In the case of receiving a moving picture, the picture is displayed on a television telephone monitor of the telephone set by a moving picture display section 25, and in the case of receiving a still picture, a key operation section 23 selects a selector 26 so as to select whether the still picture is displayed on the television telephone monitor of the telephone set or on an external monitor. In the case of outputting the still picture externally for display purpose, the still picture data is written in an external monitor display memory 29, in which plural still picture data are stored by the operation from a control section and it is possible to control the data such that the plural still picture data are synthesized or any of the plural still picture data is selected and outputted.

Description

[Detailed Description of the Invention] [Summary] Regarding a videophone device capable of transmitting both still images and moving images, a moving image display means for displaying moving image data is provided for the purpose of simultaneously displaying moving images and still images. and a still image signal output means for outputting still image data to the outside, receiving moving image data or still image data, supplying the moving image data to the moving image display means for display, and supplying the still image data to the above-mentioned moving image display means. The still image signal is configured to include selection control means for supplying the still image signal to the output means and outputting it to the outside.

[Industrial application field]

The present invention relates to a video telephone device.

Currently, there are videophone devices that can only transmit still images, but devices that can also transmit moving images are under development.

The present invention relates to a videophone device that can transmit both still images and moving images.

[Prior Art and Problems to be Solved by the Invention] A videophone device is usually equipped with one monitor, but in a videophone device that transmits both still images and moving images, it is difficult to display a moving image. If a still image is transmitted during the transmission, the transmission and display of the moving image is interrupted to display the still image, the transmitting side captures and transmits the still image data, and the receiving side displays the transmitted still image data. The data was received and displayed on the monitor of the own device, which had interrupted the above video display.

Therefore, there was a problem in that a moving image and a still image could not be displayed at the same time.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a videophone device that can display moving images and still images simultaneously.

[Means to solve the problem]

FIG. 1 is a basic configuration diagram of the present invention. In Figure 1,
1 is a selection control means, 2 is a moving image display means, and 3 is a still image signal output means.

The moving image display means 2 displays moving image data.

Still image signal output means 3 outputs still image data to the outside.

The selection control means 1 receives moving image data or still image data, supplies the moving image data to the moving image display means 2 for display, and supplies the still image data to the still image signal output means 3. Output to outside.

[Effect]

The selection control means 1 causes the moving image data to be displayed on the moving image display means 2 inside the apparatus, and the still image data is outputted to the outside, so that it can be displayed on a television monitor connected to the outside.

〔Example〕

FIG. 2 shows the configuration of an embodiment of the present invention. In FIG. 2, 21 is an encoding circuit, 22 is a selection circuit, 2
3 is a key operation section, 24 is a control section, 25 is a moving image display section,
26 is a selector, 27 and 30 are D/A conversion circuits, 2
9 is an external monitor display memory, and 31 is an external monitor device.

The encoding circuit 21 encodes moving and still image data to be transmitted to the other party's videophone call. The control unit 24 determines whether the image data transmitted from the other party's videophone call is a moving image or a still image, which is supplied from a data receiving/decoding unit (not shown), and controls the selection circuit 22 to select the received data. is supplied to the moving image display section 25 or applied to the selector 26. In this way, when a moving image is received, it is displayed on the videophone monitor of the own device by the moving image display section 25 of the own device.

When a still image is received, the selector is selected according to instructions from the key operation unit 23 as to whether to display this still image on the videophone monitor of the device itself or to output it to the outside for display on an external monitor. 26. When displaying on the videophone monitor of the own device, the still image data is supplied to the D/A conversion circuit 27 via the selector 26, converted into an analog video signal, and supplied to the videophone monitor of the own device. When outputting a still image to the outside for display on an external monitor, the still image data is written to the external monitor display memory 29 and further supplied to the D/A conversion circuit 30 to be converted into an analog video signal. and output to an external monitor device.

Here, since the still image data to be output is temporarily held in the external monitor display memory 29, a plurality of still image data can be held and these plural still images It becomes possible to combine data and control to select and output any one of a plurality of still image data.

FIG. 3 shows the arrangement when using the video telephone device of the present invention. In FIG. 3, reference numeral 11 indicates the other party's video telephone device, 12 indicates the own video telephone device, and 13 indicates an external monitor device, such as a home television receiver. That is, the video telephone device of the present invention can be used by connecting an external monitor such as a home television receiver, for example.

〔Effect of the invention〕

According to the present invention, moving images and still images can be displayed simultaneously by connecting an external monitor such as a home television receiver. Furthermore, by having a still image data memory, it becomes possible to combine a plurality of still image data or to select and output any one of a plurality of still image data.
