Abstract

PURPOSE:To easily and surely transmit the memorandums and the graphics like maps or the like with high accuracy by connecting a handwriting input device to a video telephone set main body to sand the image of the input device to the remote side and seeing the image on the screen of a display device of the TV telephone set main body. CONSTITUTION:The pictures signals stored in a memory 13 are sent to the remote side via an image control part 11, a circuit interface 10, and a truck line 8 with operation of a transmission switch 6 of a video telephone set main body 18. In this case, the handwritten input images can be superposed on the images sent from a TV camera 3 and displayed and transmitted by means of a display changeover switch 4. In addition, the signals sent from the camera 3 are cut and only the handwritten input screens can be displayed and transmitted. This switch of display/transmission is carried out when a central control part 12 receives the switch 4 and controls a switch 14 which connects/ disconnects the picture signals sent from the memory 13.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application] The present invention relates to a video telephone device that can display, store, and transmit images handwritten with a light pen.

[Conventional technology]

Devices that transmit image information using a voice telephone line include a facsimile for information on paper, and a still image videophone for static IF images. In addition to this, text and graphics can also be transmitted through personal computer communications using a personal computer, but it is also possible to transmit and display text and graphics written on the spot as if drawing a picture on paper with a pen. I can't.

On the other hand, there is a handwriting input board as a peripheral device for word processors, and by importing illustrations drawn on the board with a light pen into the word processor itself,
You can also transmit the information drawn on this board.

FIG. 3 is an external view of a conventional still image video telephone. The video telephone main body 18 has a TV camera 3, a display v#2, and various operation buttons arranged on the front 9, so that the user can take a picture of his or her face with the TV camera 3, and monitor the screen as an @ image on the display vBZ. It has become. Then, send the image (m normal image) when you press the pause button 17 to the send button 6.
By pressing , the message is sent to the other party and displayed on the display 2 of the other party's video phone (not shown).

[Problem to be solved by the invention]

However, since the dots on the display 2 screen of conventional still image video telephones are rough, it is often difficult to decipher even if characters or pictures on paper are projected onto the television camera 3 and transmitted. Furthermore, since the television camera 3 is fixed to the television telephone main body 18, it is necessary to use facsimile or personal computer communication for focusing and transmitting accurate images.

This invention was made to solve the above-mentioned problem. Simple memos, maps, etc. can be input easily by hand, and it does not require the operating knowledge or knowledge to use a facsimile machine or a keyboard itself. A videophone that can display an image or similar information as written on the display screen of the videophone without any special training, and can faithfully transmit this image to the other party. The purpose is to obtain a device.

[Means to solve the problem]

The videophone device according to the present invention includes an image detection means for capturing handwritten characters and pictures written with a light pen, a signal conversion means for converting the information into an electric signal, a storage means for storing and retaining the image information, and a means for erasing the image information. , a display means for displaying an input image, an image control means for processing an image signal, an image signal switching means for switching between a display image and a transmitted image, and a central control means for controlling their operations. It is something that

[Effect]

The videophone device according to the present invention stores the image information written on the sensor board by tracing the sensor board of the image detecting means with a light pen, and simultaneously displays it on the display, thereby making a videophone call. The image information is transmitted to the other party by the transmission operation of the device.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is an overall configuration diagram showing a video telephone device of the present invention. In the figure, 1 is a light pen for performing handwritten input, 2 is a display unit that is integrated with a sensor part consisting of a touch sensor which is a detector part for handwriting input, and pictures. In other words, this display pHl also serves as a display for displaying camera images, received images, etc. of the video telephone device.

3 is the secondary replica, camera, 4 is the display changeover switch, 5 is the erase switch, 6 is the transmission (cost), 7 is the telephone, 8 is the central office line, 9 is the TTT source switch, 18 is the video phone main body .

Erase switch 5 (, t Clears the image information stored in the memory, erases the handwritten input image on the display, and is used to enter new input from a blank slate, or when no handwritten input is performed. It is for.

Next, the operation of the above embodiment will be explained. FIG. 2 is a block diagram showing the configuration of the video telephone device shown in FIG. 1, showing only the parts related to the present invention.

In the figure, 10 is a line interface, 11 is an image control unit, 12 is a central control unit, 13 is a memory, 14 is a switch,
15 is a signal converter, 16 is a part of an input sensor,
It is made up of a touch sensor consisting of vertical and horizontal elements, and by touching it with a light pen,
The corresponding matrix detects and the signal is transmitted to the signal converter 1.
5, it is stored in the memory 13 of the storage device, and at 11 o'clock, the senna part IS is overlapped with the senna part IB on the lower side of the senna part IS.
! Il! Placed display′! The opposite point on J2 is colored 1. By continuously manipulating this original work, the characters and pictures drawn on the sensor part 161 can be sequentially printed on the desk.
At the same time, the image is displayed on the display PJZ. The image signal in the memory 13 is transmitted to the other party by operating the transmission switch 6 of the telephone main body 18, the image system 81% 11, the line interface 10,
The station line 8 is used for transmission. At this time, by using the display changeover switch 4, it is possible to superimpose an image input by handwriting on the image from the television camera 3 and display/transmit it, and also to input the signal from the television camera 3 by hand. It is also possible to display and send only images. This switching is done by controlling the operation of the display changeover switch 4 from the central control section 1.
This is done by controlling the switch 14 that connects/disconnects the image signal from the Memo'J 13. The erase switch 5 is used to return the handwritten input image on the display 2 to a blank state, and erases the hand Nb input image data stored in the memory 13. The operations of each section in the apparatus described above are controlled by a central control section 12.

It is also conceivable to be able to store handwritten input images like the self-portrait memory of conventional videophones.

〔Effect of the invention〕

As described above, according to the present invention, the handwriting input device is connected to the main body of the video phone, and the image is transmitted to the other party and viewed on the display WI@ screen of the main body of the video phone, so it is similar to a facsimile. It does not require any large-scale equipment, nor is it difficult to view pictures taken directly from a TV camera, making it possible to easily, reliably, and accurately send memos, maps, and other figures. Therefore, it is possible to further expand the scope of use of the videophone.
