JPS63280588A - Picture communication telephone set - Google Patents

Abstract

PURPOSE:To obtain a picture communication telephone set with offering convenience in use by providing a normal image and mirror image changeover means for switching into a normal image and a mirror image for a picture displayed by a picture display means. CONSTITUTION:A picture taking-in means 1, a picture display means 2, a picture transmission means 3 and the normal/mirror image changeover means 4 are provided and the picture taking-in means 1 converts a picture into a video signal to take in the result. Then the picture is displayed by the picture display means 2 by using the video signal from the picture taking-in means 1 and the picture is sent by the picture transmission means 3 and the picture displayed by the picture display means 2 is switched into a normal image and a mirror image by the normal/mirror image switching means 4. Thus, in sending an image of a person, it is easy to make a pose and the inversion of left/right side of a document is avoided in sending a document picture.

Description

[Detailed description of the invention] (Technical field) The present invention relates to an image communication telephone having an image communication function.

(Prior Art) Various systems and forms of image communication telephones in which a telephone device is equipped with an image communication function have been proposed in the past. No. 1 (1987) ``Problems and Trends in Low Bit Rate Video Communications'' by Yamaguchi and Kinuhata, etc.

However, since the image communication function of these image communication telephones is only to perform simple image communication, they are not easy to use.

(Objective) An object of the present invention is to improve the above-mentioned drawbacks and provide an easy-to-use image communication telephone.

(Structure) As shown in FIG. 1, the present invention has an image capture means 1, an image display means 2, an image transmission means 3, and a normal image switching means 4, and the image capture means 1 converts an image into a video signal. Convert and import. Then, an image is displayed on the image display means 2 based on the video signal from the image capture means 1, and this image is transmitted by the image transmission means 3, and the image display means 2
The image displayed is switched between a normal image and a mirror image by a normal image/mirror image switching means 4.

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

FIG. 2 shows an embodiment of the invention. In the figure, 11 is a color CC that captures color images and outputs NTSC video signals.
D video camera, 12 is color CCD video camera 11
Digital RG by inputting the NTSC video signal from
14 is a video signal input circuit that converts the signal into B(:) and stores it in the image memory 13;
A video signal output circuit inputs the GB signal and converts it into an NTSC video signal; 15 is a color liquid crystal display panel that inputs the NTSC video signal from the video signal output circuit 14 and displays a color image; 16 is a handset (handset)
, 17 is an audio processing circuit that processes audio signals, 18 is a modem line control circuit consisting of a modem and a line control unit, and 19 is an image compression/reproduction unit that encodes video signals to be transmitted and decodes received video signals. 20 is a system controller for overall control; 21 is a keyboard for giving commands from the outside; it has a numeric keypad 22 and function keys 23; and 24 is a public telephone line.

FIG. 3 shows the processing flow of the system controller 20.

The user presses the freeze key on the image capture keyboard 21 to select the image and image he or she wishes to transmit using the CCD video camera 711, and also uses the keyboard 21 to specify whether the image is a normal image or a mirror image. System controller 20
In response to the freeze command from the freeze key on the keyboard 21, the power is turned off by the CCD hidden i-camera 11. Captures digital RGB signals from video signal input circuit 12.

A normal image/mirror image 472 from the keyboard 2j is converted into a digital RGB signal of a normal image or a mirror image and stored in the image memory 1':S. "Next Shiko System" controller 2
0 simulates image compression and reproduction by encoding and decoding the digital RGB signals in the image memory 13 using the image compression and reproduction circuit 19, and stores the decoded digital RGB signals in the image memory 13. do. The digital RG in this image memory 13
The B signal causes the video signal output circuit 14 and the color liquid crystal display panel 15 to display an image, and the system waits for an input from the keyboard 21.

The user checks the image that the receiver sees from the image displayed on the color liquid crystal display panel 15, and if he does not like it, issues a freeze command again using the freeze key on the keyboard 21 to perform the above-described operation. If the user likes the image displayed on the color liquid crystal display panel 15, he issues an image transmission command using the transmission key on the keyboard 21. When the system controller 20 receives this image transmission command, the image memory 1
The digital RGD signal in 3 is encoded by an image compression/reproduction circuit 19, modulated by a modem line control circuit 18, and received via a public telephone line 24 (transmitted to destination B).

Further, when receiving a video signal transmitted from the destination via the public telephone line 24, the video controller 20 transmits the video signal transmitted from the destination via the public telephone line 24 to the modem line control circuit. 18, decoded by the image compression/reproduction circuit 19, stored in the image memory 13, and displayed on the video signal output circuit 14 and the color liquid crystal display panel 15.

The system controller 20 operates according to commands from the keyboard 21, but when one image communication is not to be performed, the system controller 20 causes the modem line control circuit 18 to switch the public telephone line 24 to the voice processing circuit 17 side. Therefore, the user can access the voice processing circuit 17 from the handset 16. Modem line control circuit 18
, you can make a voice call (-) with the other party via the public telephone line 24.

(Effects) As described above, according to the present invention, a means is provided for switching the image captured by the l1ril image capture means and displayed by the image display means into a normal image and a mirror image, so that when one person sends his or her own elephant, This makes it easier to pose, and when sending an image of a document, there is no need to flip the document left and right. You can also check the image before sending it, so you don't have to worry about sending an image you don't like.
By simulating image transmission and displaying it on a monitor, it is possible to check the quality of the image viewed by the recipient.
