Abstract

PURPOSE: A picture phone for displaying both transmitting and receiving pictures at the same time is provided to display the image of a caller as well as the image of the other party in a picture call. CONSTITUTION: A picture phone for displaying both transmitting and receiving pictures at the same time consists of a received picture processing part(1), a camera(2), a display part(3), a control part(4), and a picture display setting part(5). The received picture processing part(1) receives image data, containing a call partner's figure, through an antenna(6) and recovers the received data to the original image. The camera(2) photographs a caller's figure and outputs a transmitting picture. The display part(3) displays the received picture, the original image outputted from the received picture processing part(1), and the transmitting picture outputted from the camera(2). The picture display setting part(5) is to selectively set a single mode to display the received picture on the display part(3) and a dual mode to display both the received picture and the transmitting picture at the same time.

Description

TELEPHONE FOR DISPLAYING RECEIVING AND TRANSMITTING IMAGE}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a video telephone, and more particularly, to a video telephone in which a reception image and a transmission image are simultaneously displayed on a display screen during a video call.

In the video phone, the call partner is displayed on the LCD screen so that the caller can make a call while viewing the call partner.

Such a video phone can give a great satisfaction to the caller since it can make a call while looking directly at the other party's face, compared to communicating only by voice.

However, the conventional video telephone displays only the image containing the appearance of the call partner during the call, so it is not possible to know which image is displayed to the call partner by the image of the user.

Accordingly, an object of the present invention is to provide a video telephone which simultaneously displays a transmission / reception image for displaying not only an image of a call partner but also a caller's image on a display screen during a call. do.

** Explanation of Signs of Major Parts of Drawings **

1: Receive image processing unit 2: Camera

3: display part 4: control part

5: Image display setting section

To this end, the present invention provides a reception image processing unit for processing a reception image, a camera for outputting a transmission image, a display unit for displaying an image, an image display setting unit for selecting a dual mode or a single mode, and the display unit in the dual mode. And a control unit for simultaneously displaying the received image and the transmitted image and displaying only the received image on the display unit in the single mode.

Hereinafter, the present invention will be described with reference to the accompanying drawings.

Fig. 1 shows an internal configuration diagram of a video telephone which simultaneously displays transmission and reception images of the present invention.

In FIG. 1, the video telephone is composed of a reception image processing unit 1, a camera 2, a display unit 3, a control unit 4 and an image display setting unit 5. As shown in FIG.

The reception image processing section 1 receives the image data containing the state of the call partner through the antenna 6 and restores it to the original image (hereinafter referred to as a reception image).

Although the camera 2 takes a picture of the caller and outputs a transmission image, although not shown, the transmission image output from the camera 2 is transmitted to the video telephone of the call partner through the antenna 6 through a predetermined process.

The display unit 3 displays the reception image output from the reception image processing unit 1 and the transmission image output from the camera 2.

The image display setting unit 5 can selectively set the single mode for displaying only the received image on the display unit 3 and the dual mode for simultaneously displaying the received image and the transmitted image.

When the single mode or dual mode is selected in the image display setting section 5, the mode setting signal is input to the control section 4.

The control unit 4 displays only the received image on the display unit 3 in the single mode according to the mode setting signal input from the image display setting unit 5, and displays the transmitted image as well as the received image in the dual mode. Is displayed.

In the dual mode, the image display setting section 5 can set the size ratio of the received image and the transmitted image or the display position on the screen.

That is, in the dual mode, since the reception image and the transmission image are simultaneously displayed on the screen, it is necessary to set the display relationship between them.

For example, the reception image can be displayed on the entire screen, and the transmission image containing the call appearance can be displayed in a small size on the bottom right of the screen.

In addition, the reception image may be displayed at the top of the screen, and the transmission image may be displayed at the bottom of the screen.

Fig. 2 shows the operation in the video telephone which simultaneously displays the transmission / reception images of the present invention.

After the video telephone is in a call state in step S1, it is determined in step S2 whether the display mode is a dual mode.

If the display mode is not the dual mode, the process proceeds to step S3 to display only the received image on the screen. If the display mode is the dual mode, the process proceeds to step S4 to simultaneously display the received image and the transmitted image on the screen.

In the next step S5, the size ratio or the display position of the received image and the transmitted image is set so that the received image and the transmitted image can be displayed at a desired size or position.

In the video call, the caller's terminal is displayed on the caller's terminal as well as the caller's appearance to be displayed on the caller's terminal, thereby increasing the convenience of the call and increasing the satisfaction of the caller.
