Abstract

PURPOSE:To display only the picture of a specific area by an arbitrary monochrome color to diversify an editing technique by providing a control means for writing picture data in a designated area and color designating data in a memory device as a pair. CONSTITUTION:An operator designates an area for coloring the black and white part of a picture displayed in a picture output device 4 and the color by a code information input device 1. A control part 5 inputs the coordinate information of a change area to a color area recognition circuit 9 and a change color is inputted to a color designating register 10. The circuit 9, when the value of an address counter 6 coincides with the value of the area applied from the control part 5, turns a color area signal 104 on. When the signal 104 is turned on and a video signal 103 becomes black, a color designating signal generating circuit 12 operates and only the color designated by the register 10 is outputted to the device 4. The coordinate information of the circuit 9 and the chrominance information of the register 10 are added to data read from a frame memory 7, stored in an external memory device 3 and the editing technique can be diversified.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a single image editing and display device, and particularly to an image data filing system that handles black and white binary image data. The present invention relates to an image editing and display device for displaying only images in monochrome color.

[Conventional technology]

BACKGROUND ART Conventionally, image editing functions such as electronic filing systems and intelligent copiers have been capable of negative/positive inversion, trimming, masking, rotation, reduction/enlargement, and cut-and-cover composition. For example, a specific area of image data on an image memory is designated and image processing such as negative/positive inversion is performed.

In addition, as a method for image processing information in different formats on the same document, a method has been proposed that divides the data on the document into, for example, an image information area and a text information area, and then distributes the scanned image information according to the area classification. (For example, see Japanese Patent Laid-Open No. 60-581). According to the above publication, a document is optically scanned to extract an image signal, this is quantized, the quantized image data is divided into a character area and an image area, and character data in the character area is recognized. By outputting the recognized character code and image data,
Text information and image information mixed in one manuscript can be input simultaneously as they are.

Furthermore, for colorization, color information is R9G, B
Full-color scanners that capture images in three colors are often used. However, monochromatic color display of monochrome image data, for example, coloring and emphasizing a part of monochrome image data, has not yet been put to practical use.

[Problem that the invention seeks to solve]

The conventional technology using full-color scanners described above is directed toward a full-color method that adds R, G, and H color information and density information to each pixel, which makes it difficult to quickly realize color signal input technology. Color images are black and white 2
The amount of data is enormous compared to the value image data. In other words, even with black and white binary pixels, there are 16 pixels per A3 size.
At mm definition, the memory capacity for one screen is as large as 4 megabytes, so if color information and gradation information are added to this, the data for one screen will expand to several times this size. Therefore, it is difficult to put the conventional image processing technology into practical use due to the burden of large-capacity memory and the problem of data transfer time. For this reason, conventional image processing techniques include black and white inversion, rotation, enlargement/reduction, cropping, masking, partial gradation, and partial OCR of images within designated areas.
However, no attempt has been made to partially colorize the images.

SUMMARY OF THE INVENTION An object of the present invention is to solve these conventional problems and provide an image editing and display device that is capable of displaying a monochromatic image within a designated area in color.

[Means for solving problems]

In order to achieve the above object, the image editing display device of the present invention includes input means for specifying an arbitrary area of a displayed monochrome image and a monochromatic color to be added to the image within the area, and image data read from the frame memory. Among them, means for adding specified monochromatic color information to the image data in the specified area inputted by the input means, means for generating the specified color signal, and means for combining the image data in the specified area and the color specification data. It is characterized in that it has a control means for writing the data into a storage device as a pair.

[For production]

In the present invention, in order to colorize a part of black and white image data, after the operator specifies the area and color to be colored in one image data, the black and white image data and the color in the black and white image are combined. Areas and colors are managed separately, and black and white image data, color area information, and color information are combined and reproduced. That is, in the initial state, a black and white binary image captured from a monochrome scanner and stored in a frame memory is displayed as a monochrome image on the CRT display screen. While viewing this display screen, the operator inputs a code signal representing the area and color to be colored using a mouse, keyboard, or the like. The input code signal and image data are filed in a storage device as a pair. When displaying this image on a color display bag opening or printing it on a color printer, address counters in the main scanning direction and sub-scanning direction are controlled by code data indicating the area, and the starting point of the coloring area is determined. and define the end point. At the same time, code data specifying the color is input to the color signal generation circuit for R, G, and 83 colors via one color register.

Here, color information is generated, and the color information is added to the image data from the start point to the end point of the color area, and the color information is input to a color image display device or printer. In this way, the monochrome image data is displayed in monochrome color or printed in color only in the designated area. Note that the image display device can share the same color display screen for displaying a black and white screen before editing and for displaying a colored image after editing.

First, in order to input an initial image, image data is captured by an image input device 2 such as a scanner and stored in the frame memory 7 . In addition, the image data stored in the frame memory 7 is read out from a magnetic disk or optical disk, and stored in the frame memory 7.
It may be stored in . Image data stored in the frame memory 7 is read out by a memory read signal 101 generated by the address counter 6. Here, the address counter 6 operates according to the timing generated by the timing generation circuit 8. The image data signal 102 read from the frame memory 7 is transmitted to the juxtaposition data conversion circuit 11.
is converted into a video signal 103 by terminal D of the selector.
After passing through O1UD and an AND gate, the image output device i! 4 is output. That is, at this time, since the same high-level potential is applied to the selector terminals AO, BO, and CO of the signal generation circuit 14 from the power supply PU, the terminals UA and U
11" signals are output from both B and UC, which are combined with the video signal 103 from terminal UD by an AND gate and output to the image output device 4 as a black and white image.8 The operator displays the image on the image output device 4. The control unit 5 looks at the image and specifies the area where the black and white part is to be colored and its color using the code information input device 1. The coordinate information of the change area, that is, the area where the color of the image is to be changed, is input to the color area recognition circuit 9, and the change color is input to the color specification register 10.The color area recognition circuit 9.

A conveyor check is performed with the address counter 6 in units of dots, and when the value of the address counter 6 and the value of the area given from the control section 5 match, the color area signal 104 is turned on. When this color area signal 104 is on and the video signal 103 becomes black, the colorization designation signal generation circuit 12 operates to input the input stage of the R, G, B signal generation circuit 14 to AO, BO, Co terminal, Al, B i

is generated. Furthermore, when storing the color image created by the above procedure in the external storage device @3, it is possible to easily store it by adding coordinate information and color information for changing the color of the image to the black and white image information. can. That is, the black and white image ff[ is taken out as it is stored in the frame memory 7, and the coordinate information of the color area recognition circuit 9 inputted by the control unit 5 and the color information of the coloring designation register 10 are read therefrom. frame memory 7
These coordinate information and color information may be added to the image data read from the image data and stored in the external storage device 3.

In FIG. 2, the memory read signal 101' from the address counter 6 is An, An+1 . An+2, An+3
．． ... is input into the frame memory 7, image data signals 102' corresponding to the addresses are sequentially read out from the frame memory 7.

The read image data signal 102' is converted into a serial video signal 103' by the parallel-serial data conversion circuit 11. The correspondence between the video signal 103' and the image data signal 102' is indicated by a thin line. - On the other hand, when the coordinate information specified from the code information input device 1 is input to the color area recognition circuit 9 by the control unit 5 and this matches the value of the address counter 6, that is, from the middle of An in FIG. Because it matches addresses up to An+2.

Only when the video signal 103' during that period is black (
103' is low level), color specification register 1
A signal +1111 is input from 0 to the R, G, B signal generation circuit 14, and a video signal 105' of the designated color is input to the image output device 4.
is output to. On the other hand, the video signal 105' of a color other than the designated color is not output during the period of the coordinate information.

As described above, in this embodiment, a case has been described in which a monochrome image read from the image input device 2 is colored, but the present invention is not limited to this, and a monochrome image read from the external storage device 3 can also be colored. Of course you can. Further, by setting the color specification register 10, it is possible to specify not only single colors of red (R), green (G), and blue (B), but also several colors by a combination of R, G, and H. Also, when specifying multiple locations in one image with different colors,
This can be easily realized by learning the coloring designation register 10 at a plurality of locations. In addition, in this embodiment, the full seam memory for three screens normally required for color display is only needed for one screen, and when storing the image data in the storage device, only one screen's worth of image data is required. , color images can be stored and reproduced with only a small amount of additional information.

In this embodiment, since an image of a designated area that is particularly desired to be highlighted can be displayed in a single color, it has the effect that image editing and synthesis techniques can be used in many ways. In other words, important parts of a drawing document that call for particular attention may be displayed in red, or less important information parts may be displayed in less conspicuous colors, etc. to make one document easier to use. Can be edited.

Furthermore, by displaying the entire nine screens in a designated color, it is possible to classify iFs by color. Note that in this embodiment, since a color original is not imported, there is no need to develop color signal input technology, and there is a practical advantage that images can be displayed in color using only existing established technology.

〔Effect of the invention〕

As explained above, according to the present invention, only the image in a specific area that is particularly desired to stand out among black and white image data is
Since it can be displayed in any single color, it is possible to use a wide variety of editing techniques. In addition, separate from the black and white binary image data, during editing work, code data indicating the area and color can be input using the mouse or keyboard and stored in a file in pairs with the image data. This prevents an increase in the capacity of the image data, and also prevents an increase in image data transfer time.
