Embodiments of the present invention will be described below with reference to FIGS. FIG. 1 is a schematic configuration diagram showing an embodiment of a facsimile terminal device of the present invention, and FIG.
FIG. 3 is a diagram for explaining the principle of three-dimensional image communication by the facsimile terminal device shown in FIG. 1, FIG. 3 is a diagram showing various data formats of transmission data by the facsimile terminal device shown in FIG. 1, and FIG. 6 is a flowchart for explaining a procedure for storing received data by the facsimile terminal device shown in FIG.

The facsimile terminal device 21 shown in FIG.
The stereoscopic means, the transmitting means, the receiving means, and the recording means are characterized. The stereoscopic means is a means for taking in the left and right image signals of an object imaged with binocular parallax, and is composed of a stereo imager 22 and a RAM 23 here. The transmitting means encodes the left and right image signals fetched by the stereoscopic means, and the image data encoded by the encoding part 24 for each of the left and right screens or for each line or one. It is composed of a modem 25 that alternately transmits dots. The receiving means includes a modem 25 for alternately receiving the left and right image data for each screen, for each line, or for each dot, and a decoding unit 26 for decoding the left and right image signals demodulated by the modem 25. Consists of. The recording means is
The RAM 23 for temporarily storing the left and right image signals decoded by the receiving means and the left and right image signals read from the RAM 23 have different color schemes on the same recording paper, for example, one screen for each line. Alternatively, it is composed of a recording unit 27 which alternately records one dot at a time.

Since the stereo image pickup section 22 picks up an image of an object to be stereoscopically viewed through a pair of left and right camera lenses, an image of the same object is formed on the retinas of both eyes due to the difference in observation position, that is, the distance between the left and right eyes. Left and right image signals having a difference (binocular parallax) can be obtained. The RAM 23 has a storage capacity for two screens, and the left-eye image signal and the right-eye image signal output from the stereo image pickup unit 22 can be separately written in predetermined addresses. The left-eye image signal and the right-eye image signal written in the RAM 23 are sent to the encoding unit 24 as shown in FIG. 2, where they are converted into black and white binary data, and then a constant conversion code. It is encoded according to the rules. However, the encoding method can be selected from among several types, and the left and right image signals converted into binary data are alternated in units of one screen, one line, or one dot. It can be encoded. In addition, when the left and right image data are encoded in units of one screen or one line, the data length can be compressed, so that the encoded output is shown in FIG. 3 (A), (B),
As shown in (C), data indicating the time division multiplexing mode and data indicating the presence or absence of data compression are added as a header to the beginning part, and next to this header, the image signal for the left eye and the image signal for the right eye are added. The binarized image data is time-division multiplexed and continues.

In the case of alternate encoding on a screen-by-screen basis or on a line-by-line basis, there are two modes, a compressed mode and a non-compressed mode. Since there is no data compression, there is only non-compression mode, but there is no room for image quality deterioration due to data compression, so if you want to prioritize image quality, time-division multiplexing in 1-dot units is possible even if the data transfer time is lengthened somewhat. It is desirable to adopt. In this way, the left and right image data encoded by the encoding unit 24 is modulated by the modem 25 into a form suitable for the transmission path, and sent to the telephone line 11 as a facsimile signal via the network control unit 2.

On the other hand, when receiving a stereoscopic image, the facsimile signal received via the network control unit 2 is first transmitted to the modem 2
Demodulated at 5. Next, the decoding section 26 decodes the data. At that time, the data indicating the time division multiplexing mode and the data indicating the presence or absence of data compression are read from the header added to the beginning of the received data, and the data compression format is set. While performing the decoding according to, the decoded left and right image data are processed in 1 dot units or 1s according to the time division multiplexing mode.
The data is allocated to the RAM 23 in units of lines or in units of one screen.
In the distribution to the RAM 23, as shown in FIG. 4, the time division multiplexing mode is read from the header of the received data, and the judgment step (10) following step (101) is performed.
In 2), the time division multiplexing mode is discriminated in three ways.
Next, in step (102), according to the determination result, it is distributed to the RAM 23 dot by dot, line by line or screen by screen, and finally divided into left and right screens and stored in a predetermined address of the RAM 23.

By the way, the recording on the recording paper is 1 here.
The method is performed on a screen-by-screen basis. First, the image signal for the left eye is sent from the RAM 23 to the recording unit 27 and is stored on the recording paper as an image that develops blue, for example. And
When the storage of one screen of the image signal for the left eye ends, the recording paper is once rewound to the position at the start of recording. When the rewinding is completed, the image signal for the right eye is sent from the RAM 23 to the recording unit 27, and is recorded on the recording paper as an image that develops red, for example. Thus, 1 of the received stereoscopic image
Although the recording for the number of sheets is completed, the dedicated glasses 28 are worn when the received original is viewed stereoscopically. These glasses 28
A color filter is attached to each of the left and right eyes to transmit only light of a specific color. Here, a color filter made of cellophane paper of the same transparent color as that used for recording the image signal for the left eye, that is, blue cellophane paper is attached to the left eye of the dedicated glasses 28. Further, a color filter made of cellophane paper of the same transparent color as the color used for recording the image signal for the right eye, that is, red cellophane paper is attached to the right eye of the special glasses 28. Therefore, the image for the left eye and the image for the right eye recorded on the recording paper respectively pass through the color filters of the dedicated glasses 28 and are imaged on the retinas of the left eye and the right eye. Therefore, the image for the left eye is perceived by the left eye, and the image for the right eye is perceived through the right eye, and is recognized as a stereoscopic image due to the binocular parallax.

As described above, the facsimile terminal device 2
According to 1, the configuration is such that the left and right image signals of an object captured with binocular parallax are captured and coded, and are transmitted alternately for each screen, for each line, or for each dot. It takes twice as long to send visual image data as it does to send flat image data.
Basically, three-dimensional images can be transmitted using the telephone line 11 by time-division-multiplexing and transmitting the left and right image data to a facsimile signal transmitted as plane image data. Further, when the dots are alternately transmitted, the data is transmitted without data compression, so that the image quality priority data can be transmitted. When the images are alternately transmitted for each screen or line, By performing data compression, the data transmission time can be shortened. Therefore, by making full use of various transmission modes in consideration of image quality and transmission time, and by transmitting the shape of the product sample etc. to the business partner with a three-dimensional effect, the product market can be activated and the product model to be commercialized. Can be sent to the planning department from a remote development site.

In the above embodiment, the received left and right image data is alternately recorded for each screen, but it may be alternately recorded for each line. In that case, instead of feeding the recording paper once for recording the image for the left eye and recording the image for the right eye, after recording one line of the image for the left eye, the recording paper is moved to the same paper feed position. One line of the image for the right eye can be recorded while stopped, and therefore 1
The recording paper need only be fed once to record one stereoscopic image, and the structure of the receiving mechanism unit 14 can be simplified accordingly. Further, when the image data time-division-multiplexed in units of 1 dot is received, the left and right image data are alternately recorded one dot at a time, so that a stereoscopic image with excellent resolution and high stereoscopic effect can be reproduced. .

[0014]

As described above, according to the present invention, the left and right image signals obtained by picking up an image of an object with binocular parallax are fetched and coded, and for example, one screen unit, one line unit or one.
Since the configuration is such that dots are alternately transmitted, it takes twice as much time to transmit one stereoscopic image data as it does to transmit planar image data. By transmitting time-division multiplexed left and right image data to a facsimile signal transmitted as, it is possible to transmit a three-dimensional image using a telephone line. By sending data without data compression, it is possible to send data with priority on image quality, and when sending one screen or one line alternately, shorten the data sending time by applying data compression. Therefore, by making full use of various transmission modes that take image quality and transmission time into consideration, the product market and other shapes can be transmitted to the business partners with a three-dimensional effect, or The product model to be commercialized, an excellent effect of the like can be or sent to the Planning Department from the development site of a remote location.

Further, according to the present invention, the left and right image signals alternately received, for example, in the unit of one screen, in the unit of one line or in the unit of one dot are decoded and recorded on the same recording paper with different color arrangements on the left and right sides. , The left-eye image and the right-eye image are recorded on the recording paper by wearing glasses with different left and right transmitted colors, and the left-eye image and the right-eye image are retinas of the left-eye and the right-eye, respectively. The images for the left eye can be perceived by the left eye, and the images for the right eye can be perceived through the right eye, and can be recognized as a stereoscopic image due to binocular parallax. .

Furthermore, the present invention provides a function as a transmitter for transmitting a left-eye image and a right-eye image, and a receiver for recording the received left-eye image and right-eye image as a stereoscopic image. By combining the functions, it is possible to install the minimum required functions as a commercially available facsimile terminal device, and thereby send and receive stereoscopic image data with a facsimile terminal device having the same function. With this, it is possible to receive the signal.
