[Problem that the invention seeks to solve]

Now, in such conventionally developed drawn image communication devices, the only image input device is a drawing pad for inputting drawn images by hand. There was a slight inconvenience in that it was not possible to send already created images of printed matter or the like to the communication partner. As a solution to these difficulties, a configuration may be considered that includes an image reading device, for example, a so-called scanner, which is mainly used in facsimile machines and the like.

On the other hand, for hand-drawn images manually drawn from a drawing pad, for example, by providing a switch to specify the color, the entire drawn image or the lines drawn in each part can be manually colored in different colors, displayed, and transmitted. A device is being developed. However, since the image reading device described above inputs images in two colors, black and white, there is an imbalance in that one type can be manually input and displayed in color, while the other can only be input and displayed in black and white.

〔Example〕

Hereinafter, the present invention will be described in detail based on drawings showing embodiments thereof.

The figure is a block diagram showing the configuration of a drawn image communication device according to the present invention.

The telephone 1 is connected to the demultiplexing circuit 56 of the control unit 5.
It is used for connecting a telephone line with the other party and for inputting and outputting voice, and also functions as a telephone by itself.

The scanner 2 is an image reading device that optically reads an already drawn image or a relatively simple printed matter using an image sensor, converts it into an electrical signal in the form of a dot pattern, and outputs the electrical signal. is an interface 54 connected to a microprocessor 53 which is an image signal processing device.
is given to.

Note that the scanner 2 normally reads an image drawn with black lines on a white background as a binary signal, with the white part being "0" and the black part being "1".This will be explained later. When displayed on color monitor TV 4 without color specification, °l
The " part is issued and displayed, and an image with white lines drawn on a black background is displayed.

The drawing pad 3 is connected to the interface 52 of the control unit 5 and converts handwritten drawings into electrical signals using, for example, a pressure-sensitive sticker and outputs the electrical signals to the interface 52. That is, the hand-drawn image drawn on the drawing pad 3 by the input ben has X, Y (representing the moving distance at each sampling timing to reach the X-Y coordinate set on the drawing pad 3), and Z. (Indicating whether or not the input pen is in contact with the drawing pad 3) is converted into a signal and output to the interface 52. Note that this drawing pad 3 has an operation button 3 for specifying and inputting the color of the lines of the drawn image (8 colors as described later) when inputting the hand-drawn image.
1, and indicator lamps 32 and 33. Further, as will be described later, the operation button 3 is capable of storing the background of the image read from the scanner 2 and the image itself, that is, each of the drawn lines of the image, in the R3G, B, and memory 51 as separate color displays. In this case, the colors of the background and drawn lines are specified in accordance with instructions to turn on the display lamps 32 and 33.

The color seven-unit television 4 displays a drawn image inputted by hand from the drawing pad 3 or an image inputted by the scanner 2, and also displays an image transmitted from the other party via the telephone line 6. Specifically, the image signal of the hand-drawn image input from the drawing pad 3 is processed in the same manner as in the conventional drawing image communication device, and the image signal input from the scanner 2 is processed as described above (the drawing pad 3 When a color is designated using the operation button 31, the video signal is processed into R, G, B, and three-color video signals and stored in each color page of the R, G, and B memory 51. Once stored, the stored contents of each color page are compositely displayed on the color monitor TV 4 to perform a color display.The image signal from the other party input from the telephone line 6 is displayed in color. are stored in corresponding color pages of the R, G, B, memory 51, respectively, and in the case of black and white display, the same black and white display signals are stored in the R, G, B, memory 51.
A total of pages of each color are stored in °ζ.

Next, the configuration of the control section 5 will be explained.

1? , G, B, and the memory 51 stores the video signals of each color corresponding to each of the three primary colors provided from the microprocessor 53 in the corresponding color page (R, G, B, storage area in the memory 5), Each time the images are combined and output to the color monitor television 4 according to instructions from the microprocessor 53, the image is displayed in color.

The modem is a modem for transmitting and receiving digital image signals through the telephone line 6.

The demultiplexing circuit 56 multiplexes the modulated image signal provided from the microprocessor 53 via the modem 55 and the audio signal input from the telephone 1, and outputs the multiplexed signal to the telephone line 6. The signal is separated into an audio signal and a modulated image signal, and the signals are provided to the telephone set 1 and the modem 55, respectively.

The microprocessor f53 processes each image signal, is the control center of the control unit 5, and has an interface 52.
54 or the telephone line 6, etc.

Regarding the operation of the apparatus of the present invention configured as described above, when the microprocessor 53 shown in the table stores the image signals given from the scanner 2 into the R, G, B, memory 51,
The processing state of an image signal into R, G, and 8.3-color video signals will be described below with reference to the J conversion table.

In addition, in the table ", rDJ is the signal as read by scanner 2, rDJ is the inverted signal of the signal read by scanner 2, and the dot "1" (corresponding to the black part in the original image) is the inverted signal of the signal read by scanner 2. The dot 1- of "O" (corresponding to the white part in the original image) and the dot of '0' mean the inverted signal of the dot of 01', respectively, and "1" means that all dots are 1- ”, “
0” means that the dots in the total ゛() are “work”.

Table also shows 8 colors depending on the combination of presence/absence of each of the three primary colors (
(white, black, red, green, blue, yellow, magenta, cyan) can be expressed.

When inputting a ready-made image using Scanner 2,
The microprocessor 53 processes the signal in the form of a tone pattern input from the scanner 2 as an image signal, and also processes the signal read by the scanner 2 as a black and white image signal in its original form ( The white background of the original image is displayed as black and the black lines are displayed as white) to the color monitor TV 4.
Exactly the same signal is stored in each color page of 1. As a result, the image is displayed on the color monitor television 4 with a black background and white drawn lines of the image (background: black, drawn IjI: white columns).

Conversely, if the microprocessor 53 is instructed to display the background in white and the image in black, the microprocessor 53 inverts the black and white image signal input from the scanner 2, that is, the white part becomes black and the black part becomes black. Is the same signal inverted to white? , G, B, and each page of the memory 51. This results in
On the color monitor television 4, "C" is displayed with a white background and black drawn lines (background: white, drawn lines: black column).

On the other hand, if the microprocessor 53 is instructed to display the background in red and the drawn lines in the image in white, the microprocessor 53 converts all the black and white image signals input from the scanner 2 to "1".
The signal converted to (white) is converted into R, G, B, and R(
The signal as it is is stored in the G (green) and B (blue) pages respectively.

As a result, since all pages of R are "1", the entire screen of the color monitor TV 4, that is, the background becomes red,
Pages G and B, whose image drawing lines are represented by "1" (white), are combined with this, and the drawn line parts are I? ,G,B 3
Since the color is different, it is also displayed in white on the screen of the color monitor television 4 (background: red, drawn line: white column).

Similarly, for the combinations of other colors, the background and drawn lines are created by combining the signals of the three primary colors as they are read from the scanner 2, their inverted signals, all "1"s, and all "0s". Expressable.

In this way, the image signals stored in each color page of the R, G, and B memory 51 are displayed on the color monitor television 4 so that the background and drawn lines are each displayed in the specified color. Of course, the signal is processed appropriately by the microprocessor 53 and the modem 55, and is further multiplexed with the audio signal input from the telephone 1 by the demultiplexing circuit 56 and output to the telephone line 6.

[Effect 3 As described in detail above, the graphic image communication device of the present invention has a relatively simple device configuration, and can easily input existing images in color, transmit and receive them, and display them on a display device. A device is realized.
