DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An example in which the information communication system of the present invention is applied to a video conference system will be described in detail below with reference to FIG.

In FIG. 1, 1 is a communication control circuit,
For example, it has a codec and compresses data (image, audio data, etc.) to be transmitted from the image control circuit 4 or the camera 2 which will be described later, and transmits the compressed data to the communication control circuit 7 of the other party via the cable 6 and the other party. The compressed and transmitted data from the communication control circuit 7 is expanded by a codec to obtain original data, and the data is supplied to the image control circuit 4.

The image control circuit 4 has an input means (not shown) such as a keyboard, a joystick, a trackball or a mouse, and monitors the data sent from the other party after carrying out a predetermined process described later. In addition to displaying as an image on the tube surface 5 (for example, outputting an image and sound), the image data read from the image scanner 3 is subjected to compression processing (for example, run length encoding or Huffman encoding processing). Predetermined processing is performed and the result is supplied to the communication control circuit 1.

In this example, it is assumed that the image scanner 3 reads various materials (graphs, etc.) used in a video conference, and the camera 2 images a person.

Therefore, the image data of, for example, a person obtained by imaging with the camera 2 is compressed by the communication control circuit 1 and then supplied to the communication control circuit 7 of the other party via the cable 6.
The image data captured by the image scanner 3 is subjected to compression processing and predetermined processing in the image control circuit 4 and then through the communication control circuit 1 (or after being compressed).
It is supplied to the communication control circuit 7 of the other party via the cable 6. Here, the image and voice data (when the camera 2 is equipped with a microphone) captured by the camera 2 and the scanner 3 are used.
The image data of the material obtained by reading in (1) is transmitted separately to the other party in terms of time.

The picked-up image and voice data (taken by the camera 2) transmitted to the other party are decompressed in the communication control circuit 7 and then supplied to the monitor 5 via the image control circuit 10, The image is displayed on the tube surface as an image and is output from, for example, a speaker.

On the other hand, the image data of the material transmitted to the other party is decompressed in the communication control circuit 7 (decoding processing is performed for the data which has been run-length coded or Huffman coded), after which it is displayed on the monitor 5. It is supplied and displayed as an image on the tube surface.

Here, as an example, in the case where the device as the other party sends the image taken by the camera 8 or the voice data or the image data read by the image scanner 9 to the device as the transmission source. 1 is similar to the above, and the communication control circuit 7 shown in FIG. 1 is the communication control circuit 1, the image control circuit 10 is the image control circuit 4, the image scanner 9 is the image scanner 3, and the camera 8 is the camera 2. The monitor 11 has the same configuration as the monitor 5, respectively.

Here, the above-mentioned predetermined processing will be described with reference to FIGS. 6 and 7. FIG. 6A shows an example of material captured by the image scanners 3 and 9 shown in FIG. 1. When the information of this material is read as image data by the image scanners 3 and 9, it is read as shown in FIG. 6A. The material is displayed as an image on the screen of the monitor 5 or 11.

Here, the user can perform various processes on the material read by an input device (not shown) of the screen control circuit, such as a mouse. FIG. 6B is an example in which an underline is added below the “sales table”. As a procedure for attaching this underline to a desired portion, for example, by moving a pointing device such as a mouse, the cursor is moved to the start point of the desired position on the screen, and then clicked once to move the cursor to the desired position. After moving the cursor to the end point, click or double click, or press the return key (not shown) on the keyboard.

In this example, the cursor is moved to the "sale" portion of the "sales table" by clicking the mouse, and then the cursor is moved to the "table" position and then clicked or double-clicked. Alternatively, by pressing the return key, it is possible to underline the "sales table" as shown in the figure. In this example, this is referred to as a drawing mode or the like.

Further, in this example, a desired color can be added to a desired range of the image data read by the image scanner 3 or 9. The mode in which this color is added is called, for example, a coloring mode.

7A and 7B respectively show examples in which a desired color is added to a desired range of a material in the coloring mode.
Since the addition of this color naturally designates the range, the coordinates are designated.

When a mouse is used, the mouse is clicked once at the upper left corner of the desired range of the image of the material displayed on the screen of the monitor 5 or 11, and then at the lower right corner of the desired range. A method of designating a range by clicking again or double-clicking, for example, as shown in FIG. 7B, when it is desired to color only the part corresponding to item b of the image of the material, etc. In this case, click on any line in the closed area, or double-click, or click in the upper left corner of the desired area and then move in any direction to automatically move the area. Draw a quadrangle to notify the user, and if the user clicks or double-clicks after stopping the movement, the area enclosed by the lines that form the quadrangle formed at that time How the desired range can be considered.

That is, in this example, a line or a color is added to the material to be sent to the other party so that the material can be easily understood by the other party.

The image data of the material to which the line and color information is added in this way is transmitted to the other party in the following format, for example. That is, only the image data is compressed in the image control circuits 4 and 10, and the range data and the color data specified by the user are added to the image data of the compressed data and then supplied to the communication control circuit 1. Then, the image control circuit 10 is supplied from the communication control circuit 1 via the cable 6 and the communication control circuit 7 of the other party.

When the image data, range data and color data of the material are supplied to the image control circuit 10, the image control circuit 10 will be described with reference to FIGS. 6 and 7 based on the image data, range data and color data of the material. Image data obtained by adding lines and colors to the image data of the material as shown (created in the image control circuit 4) is restored, and the image data of the restored material is supplied to the monitor 11 and is displayed on the screen. As an image.

The image of the material displayed on the screen of the monitor 11 is different from the image data of the original material read by the image scanner 3, and a line or color is added to a necessary portion. Therefore, it becomes very understandable to the other party to whom it is sent, which makes the conference in the video conference system very smooth. Especially, in the video conference system, since it is necessary to communicate with a person at a remote place, such detailed consideration is effective.

In this description, the communication control circuit 7
Although the device having the communication control circuit 1 has been described as the partner, the same applies to the case where the device having the communication control circuit 1 is the partner.

By the way, when the data of the material is read as an image by the image scanners 3 and 9, for example, the data which is originally one line, and therefore even if the gradation is originally applied, all the density should be the same. In many cases, the density of the contour portion of the data is output differently.

In the case of coloring the output data in which the density of the contour portion is different, the line becomes thin (looks thin) or becomes thick depending on which density is to be filled. Or it may look thick and may be different from the original data.

This will be described with reference to FIGS. As an example, a region x indicated by a broken line in FIG. 10 among the data obtained by reading the data of the material as shown in FIG. 10 as an image by the scanner 3 or 9 shown in FIG. 1 will be described.

FIG. 11 shows a region x indicated by a broken line in FIG.
As shown in FIG. 11, each structural unit (for example, dot) of the data (the upper end portion of the graph of the item b) in the region x shown by the broken line in FIG. 10 is shown.
For example, the gradation is expressed by the numerical value "1" having the lowest density to the numerical value "4" having the highest density.

As can be seen from FIG. 11, when the data of the material is read as an image by the image scanner 3 or 9, they are essentially the same (in this case, one line), that is, the densities are all the same value. What should be output is output in pieces.

When coloring the data shown in FIG. 11, the coloring reference is, for example, inside the data and is "1".
When less than is specified, the shaded area is colored as shown in FIG. 12, but "1" protruding inward
Since no color is applied to the part, when projected on the monitor 5 or 11, the data of the value of “1” protruding inward appears to remain whitish, impairing the image quality of the material. I will end up.

However, if the coloring reference is set to the inside and "3" or less is specified, as shown in FIG. 13, the inside "1" of the data shown in FIG.
All the data of the values of “2” and “3” are filled in, and when this is displayed on the screen of the monitor 5 or 11, the line becomes thin, and not only the image quality of the material is impaired, but also graphs and characters are displayed. Becomes difficult to read.

Therefore, in this example, when coloring the image data to which gradation is applied, in order to prevent the erosion of the data such as the part which remains whitish or the line of the material, the density is changed according to the gradation when performing the filling. Try to change.

FIG. 8 shows the case of black and white. As shown in FIG. 8, from white with the lowest density to black with the highest density is divided into, for example, 16 levels (16 gradations). That is, the black and white expression can be expressed by 16 (4 bits) gradation R, G and B, respectively. That is, the data whose gray level is 0 is R,
G and B are expressed as 0 respectively, data of gray level of 1 is expressed as R, G and B are expressed as 1 respectively, and ... data of gray level of 15 is expressed as R, G and B of 15 respectively. Express as.

FIG. 9 shows a case of red color, for example.
As shown in, the bright red having the lowest density (red having the lowest black density) to the dark red having the highest density (red having the highest black density) is divided into, for example, 16 levels (16 gradations).
In other words, each of the red expressions has 16 (4 bits) gradation of R and G.
And B. That is, all 16 levels of R are set to the maximum value of 15, the data of 0 for red color is represented as R, 15 for G, 0 for B, and 15 for data of 1 for red color. , G is represented as 1, B is represented as 1, ...
Is expressed as 14, and B is expressed as 14. In addition, in this figure, as shown in FIG.
Since B and B are all black, their illustration is omitted.

That is, as shown in FIGS. 8 and 9, the respective densities of R, G, and B are determined in accordance with the densities of the gradation-graded image data, and the image data can be filled with red, for example. In accordance with the density of the color, for example, whitish red, blackish red, and the like, the color is given a density to be colored.

For example, in the image data as shown in FIG. 11, for example, "1" and "2" which are inner boundary portions.
Also, the data portion of the value of "3" is colored based on the density of these data.

By doing so, as shown in FIG.
The shaded area is filled with the specified color, including the data of the inner "1", "2", and "3" values, but the value of "1" in the shaded area The data of is colored with a color close to white (bright) among the specified colors,
Data with a value of "2" is colored with a specified color that is closer (darker) to black than data with a value of "1", and data with a value of "3" is a specified color that is closer to black than data with a value of "2". Colored,
Data having values other than "1", "2", and "3", that is, a portion having no data in the inner shaded area is colored with a designated color that is closest to white.

Therefore, in the example shown in FIG.
Even if the data portion of the value of “4” is black and the data portion of the value of “2” or “3” inside is the designated color, the data of the value of “2” or “3” is “4”. Since the specified color is as close as possible (dark) to the data of "value", the value of "4" is displayed when the image is displayed on the screen of the monitor 5 or 11 after this process. The data and the data having the values of “2” and “3” are seen as one line by the user's eyes.

In the shaded area, the protruding data of value "1" is the data of value less than "1", that is,
If the portion without data, that is, the portion without data, is designated as the brightest designated color, the designated color has the brightness closest to this brightest designated color. When projected as an image on the tube surface, the data of "1" value and the part without data appear as the same to the user's eyes, and only the data of "1" value appears whitish. I can't see it.

In FIGS. 8 and 9, the gradation is shown as 16 gradations from 0 to 15, but in FIGS. 11 to 14 it is set to 1 to 4 for convenience of description, and further 16 gradations are provided.
I try to express it in gradation. Further, when the gradation at the time of expression is small as in this case, for example, the minimum value “0” is set for “0” and the maximum value “1” is set for “4”.
5 "for the remaining" 1 "to" 3 "
Although "14" may be equally divided and assigned, the remaining portion may be assigned, for example, according to the preference of the user. However, if data is not retained in a whitish color and the line is not thin, "1" to "2" for "1" and "2" or "3" for For example, it may be necessary to assign a large value such as "13" or "14" (of course for color data other than the designated color).

Next, the operation of the video conference system shown in FIG. 1 will be described with reference to the flow charts of FIGS. Incidentally, among the blocks showing the processing of these flowcharts, the processing in the block to which the double line is applied indicates the decoding processing (subroutine).

First, in step 100, the material is read from the image scanner. Then, the process proceeds to step 110. That is, the image control circuits 4 and 10 shown in FIG. 1 take in the image data of the material read by the image scanners 3 and 9.

In step 110, the material is displayed with gradation. Then, the process proceeds to step 120. That is, as described above, the image data of the material taken in by the image control circuits 4 and 10 is gradation-adjusted and the monitor 5 or 11 is displayed.
It is supplied to and projected as an image on the tube surface.

In step 120, the material is colored. Then, the process proceeds to step 130. That is, as described above, when the user specifies the range to be colored and the color to be added to the specified range through the keyboard, mouse, trackball or joystick on the screen of the monitor 5 or 11, the specification is based on the specification. Image control circuit 4 or 1
0 colors the designated area of the image data of the material.

In step 130, it is determined whether or not to save the material. If "YES", the process proceeds to step 140, and if "NO", the process proceeds to step 160. That is, for example, the image control circuit 4 or 11 displays a message or the like indicating whether or not to save the material on the screen of the monitor 5 or 11, and the user inputs "YES" or "NO" here. For example, it is determined whether or not the "Y" or "N" key on the keyboard is input.

In step 140, the image data of the material is compressed and saved. Then, the process proceeds to step 150. That is, the image control circuits 4 and 11 store the image data of the material in a memory (not shown), a floppy disk of a floppy disk drive, a magneto-optical disk mounted on a magneto-optical disk device, a hard disk device, a silicon disk device, or the like, for example, run length. It is stored or recorded by performing encoding or Huffman encoding processing.

In step 150, the colored data is saved. Then, the process proceeds to step 160. That is, the color data of the material generated in step 120 is stored or recorded together with the range data in various types of storage, or in the medium of the recording device, as described above.

In step 160, the material is transferred. And it ends. That is, the material data, the color data, and the range data are transmitted to the communication control circuit 1 or the communication control circuit 7 via the cable 6.

FIG. 2 is a flowchart showing the coloring process for the image data of the material in step 120 of FIG.

First, in step 200, a coloring function is selected. Then, the process proceeds to step 210. That is, for example, when the user selects “coloring” using an input device such as a keyboard or a mouse on the menu image displayed on the screen of the monitor 5 or 11, the mode is shifted to that mode,
Further, the function for performing the coloring is also designated on the screen. This function includes, for example, a function for drawing a line, filling a quadrangle, and filling a closed area.

In step 210, a coloring color is selected. Then, the process proceeds to step 220. That is, for example, when the user selects a desired color using an input device such as a keyboard or a mouse on the menu image displayed on the screen of the monitor 5 or 11, the selected color is set.

In step 220, the colored coordinates designated by the pointing device are set. Then, the process proceeds to step 230. That is, the coordinates (for example, the upper left corner described in FIGS. 6 and 7) designated on the image by the user via the keyboard, mouse, trackball, joystick, or the like are stored.

In step 230, it is determined whether or not two coordinates are required. If "YES", the process proceeds to step 240, and if "NO", the process proceeds to step 250. That is, for example, it is determined whether or not the coordinates stored in step 220 are lines forming a closed area.
Since the range can be obtained only by specifying 0, the process proceeds to step 250. In other cases, the user specifies the coordinates on the image via the keyboard, mouse, trackball, joystick, etc. (for example, FIG. 6). And the lower right corner described in FIG. 7) are stored.

In step 250, the coloring function is executed. And it ends. That is, the designated area is filled with the designated color as described above.

FIG. 4 is a flow chart showing a process for simply coloring the material in step 110 shown in FIG.

First, in step 300, the material is displayed with gradation. Then, the process proceeds to step 310. That is,
It is supplied to the monitors 5 and 11 in a state where the image data of the material is adjusted and displayed as an image on the tube surface.

In step 310, the coloring range is determined. Then, the process proceeds to step 320. That is, the range designated by the user is set as the coloring range.

At step 320, one dot within the range is read. Then, the process proceeds to step 330.

In step 330, it is judged whether or not the dots read in step 320 are black. If "YES", the process proceeds to step 340, and if "NO", step 3
Move to 50.

In step 340, the dot read in step 320 is given the specified color. And step 3
Move to 50.

In step 350, it is determined whether or not the range has ended. If "YES", the process ends, and if "NO", the process proceeds to step 360.

At step 360, the next dot is read. Then, the process proceeds to step 320 again. That is, for example, the address of the dot to be read is incremented. That is, the data is sequentially read dot by dot from a predetermined position of the designated area, and if the density is other than the density indicating black, the processing of painting the designated color is performed on the entire designated area.

FIG. 5 is a flow chart showing a process for gradationally coloring the material in step 120 shown in FIG.

First, in step 400, the material is displayed with gradation. Then, the process proceeds to step 410. That is,
It is supplied to the monitors 5 and 11 in a state where the image data of the material is adjusted and displayed as an image on the tube surface.

In step 410, the coloring range is determined. Then, the process proceeds to step 420. That is, the range designated by the user is set as the coloring range.

At step 420, one dot within the range is read. Then, the process proceeds to step 430.

In step 430, it is judged whether or not the dots read in step 420 are black. If "YES", the process proceeds to step 470, and if "NO", step 4
Move to 40.

In step 440, it is judged whether or not the dot read in step 420 is white. If "YES", the process proceeds to step 450, and if "NO", step 4
Move to 60.

In step 450, the color specified in the dot read in step 420, that is, red, which is the reddest in the black component (lightest), is painted.

At step 460, a gradation color is added according to the density of the dots read at step 420.
Then, the process proceeds to step 470.

In step 470, it is determined whether or not the range has ended. If "YES", the process ends, and if "NO", the process proceeds to step 480.

In step 480, the next dot is read. Then, the process proceeds to step 420 again. That is, for example, the address of the dot to be read is incremented. That is, data is sequentially read dot by dot from a predetermined position in the specified area, and if the density is other than the density indicating black, the specified color is gradation-adjusted and applied to the entire specified area. .

As described above, in this example, in the video conference system, for example, the material to be transmitted to the other party is read, the read material is drawn, the designated area is colored, and the density is designated in the designated area. Since the color tones according to the above are added, the other party to whom the image data of the material processed in this way is sent can deepen the understanding of the material and hold the video conference efficiently. be able to. For example, when the provider of the material wants to appeal the material to the other party in the video conference, by coloring it, or by coloring it, or by adding a line etc. to the necessary part The effect can be enhanced.

Further, when coloring is performed, the specified range is colored with a density according to the gradation, so that, for example, whitish data can be seen to remain on the image displayed on the monitor 5 or 11. It is possible to prevent the deterioration of the image or the deterioration of the information such that the lines and characters are eroded and thinned, and the image data of the material can be satisfactorily transmitted to the other party.

The above embodiment is an example of the present invention.
It goes without saying that various other configurations can be adopted without departing from the scope of the present invention.

The color information adding means adds color information to the range designated by the designating means, and the read information having the color information added to the range designated by the color information adding means is transmitted to the destination by the transmitting means. Therefore, the other party can deepen the understanding of the material and can efficiently hold the video conference. For example, it is particularly effective when the provider of the material wants to appeal the material to the other party in the video conference.

Further, according to the present invention described above, the color information adding means reads the information of an arbitrary unit within the range designated by the designating means, and adds the color information based on the density of the read information of the arbitrary unit. As a result, in addition to the above effects, for example, the protrusion data may remain whitish on the screen due to variations in density during gradation expression, or the original line or character thickness during reading may be different (especially thin). It is possible to prevent the deterioration of the image quality due to, for example, turning on.

Further, according to the present invention described above, the color information adding means sequentially reads the information in the range designated by the designating means, and when the density of the read information is the highest, the color information is added to the information. If the density of the read information is the lowest, the color information of the highest density is added to the information, and the density of the read information is higher than the lowest density and the highest density. If it is lower, gradation information is added to that information. Therefore, in addition to the above effects, the image quality transmitted to the other party can be improved.

Further, according to the present invention described above, the color information adding unit regards the information of the adjacent portion of the specified range outside the specified range as a density higher than the actual density by a predetermined amount, and the information of the specified range and the specified range. Since the gradation color information having different densities is added to the information of the adjacent portions of, the reproducibility of the read original data can be improved and good image data can be transmitted in addition to the above-mentioned effect.

Furthermore, according to the present invention described above, the density of the color information added to the designated range is set lower than the density of the color information added to the adjacent portion of the designated range. The distinction between the range and the outside of the specified range can be visually clarified.

Further, according to the present invention described above, the read information, the range information obtained by the designation by the designating means, and the color information added by the color information adding means are respectively transmitted to the destination by the transmitting means. Therefore, in addition to the effects described above, it is possible to obtain image data obtained by processing at the other party in a simple and reliable manner.

Further, according to the present invention described above, transmitted image information, range information related to the color information of this image information,
The receiving means receives the color information for adding the color information to the image information based on the range information, and adds the color information to the designated range of the image information based on the image information, the range information and the color information from the receiving means. Then, the original information is reproduced by the reproducing means, and the reproduced output from this reproducing means is displayed on the display means, so that the transmitted information can be reproduced in the same state as the information at the transmission source. As a result, for example, in a video conference system or the like, it is possible to deepen the understanding of the transmission information from the transmission source and to hold the video conference smoothly and favorably.
