Abstract

PURPOSE:To execute guidance against the coloring editing of a user and to easily generate a document which is appropriately colored. CONSTITUTION:At the time of designating a color for the constitution element of the document in a document processor, the user previously designates how to restrict the coloring of the document by a color mode designation means 18. A color designation change part 14 restricts the range of the color which can be designated for the constitution element of the document by using a color table held in a color table holding part 17 holding coloring information in accordance with the designation. If an OHP mode is selected as the mode of coloring restriction when the document that the user generates at present is OHP, for example, a comparatively darker color looks more attractive in OHP at the time of projection. Thus, color information that the colors added to a character and the graphic element are restricted to the darker colors is used.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document processing apparatus such as a word processor capable of handling colors.

[0002]

2. Description of the Related Art Due to recent technological advances, it has become possible to easily create a document in a document editing editor on a word processor or a workstation.
Recently, its functions have been further enhanced and it has become possible to create color documents. By outputting it to a color printer, a color document can be easily created.

When specifying a color in a document editing device such as a word processor, it is usual to specify a certain absolute color for a certain constituent element in the document.
This is a commonly used method. As used herein, "designating an absolute color" means directly designating a certain color. In other words, in a certain document, the designation such as "blue" for "title" and "red" for "author" is
Colors such as "red" and "blue" are directly specified as the attribute of the character indicating "title" or "author name". For example, when you want to color a part of a character string of a document in the document processing device J-Star of Fuji Xerox Co., Ltd., select the character string to be colored, open the property sheet, and then there. Use the method of specifying the color you want to specify for the column (issued by Fuji Xerox Co., Ltd., “G
GlobalView Color Workstation Additional Instructions "). In the case of this example, it is a character, but in the case of a graphic, the graphic element to be colored is selected, its property sheet is opened, and the color is directly specified. At that time, if the color that can be specified at that portion is a character, the color that can be specified is the same for any character, and the same is true for a graphic element. Other document processing devices also differ in whether or not they are specified using a method called a property sheet, but when specifying colors for character strings, graphic elements, etc., there is no case where the range of colors that can be specified is different. .

[0004]

However, since various colors can be used when coloring, it is necessary for the user to know what part is colored and how a good-looking document can be obtained. As a result, there is a problem that appropriate coloring is performed subjectively by the user, and as a result, coloring that is not so good is performed.

On the other hand, in order to solve such a problem, when the purpose or impression of a document is input, the system reads the structure of the document and automatically applies the coloring / layout to it by using the knowledge of the color / layout. A technique of performing is proposed (Japanese Patent Application Laid-Open No. 4-14170).
However, there is a drawback in that the documents output by such a system are uniform. This is because the same layout and the same coloring are always applied when a certain knowledge is used. Therefore, the work of post-editing the automatically generated document occurs in order to avoid uniformization. At this time, in the end, similar to the problem at the time of editing, there is no guide as to which part and how to change, and as a result, there is not much for the automatically generated good document. The problem is that you make changes that aren't good.

The present invention aims to solve the above-mentioned problems of the prior art. That is, an object of the present invention is to provide a document processing device which can guide a user to color editing and can easily create a document with appropriate coloring.

【Example】

(Embodiment 1) In this embodiment, a color mode function is added to a conventional document processing apparatus. FIG. 1 shows a block diagram of this embodiment. In this embodiment, as a conventional technology part, a document input unit 10 for inputting a document, a component holding unit 11 for holding the input document, a layout unit 12 for laying out the input document, There is a visualization unit 13 for displaying the laid out document, and a color designation unit 101 as a part of the function of the document input unit 11. The color designation unit 101 is often realized as a part of the function of setting the attribute of a component. In the case of an example called a property sheet as shown in FIG. 2, a function of designating a color is realized as a part of a function of setting attributes such as a font and font size for a character string. In this example, the character color is realized in the character color portion at the bottom of the property sheet by selecting the color desired by the user from the sample of the specifiable colors.

In this embodiment, in addition to these conventional techniques,
Further, according to the designated color mode, the color designation unit 10
It is characteristic that the function for guiding the user's coloring and editing is realized by limiting the color that can be designated by 1. The schematic configuration will be described below. First, in the color mode designation unit 18, the user selects a color mode according to the image of the document, the purpose, and the like. The selected color mode is transmitted to the color table holding unit 17. The color table holding unit 17 holds a table of colors that can be used for each color mode. The color table holding unit 17 refers to the color table in the color mode designated by the color mode designation unit 18, and changes the value of the color table to the color designation changing unit. Hand over to 14. The color designation changing unit 14 has a role of replacing the color table of the sample colors used in the color designation unit 101 with that of the color table of the designated color mode. When the color mode is designated as described above, a process of limiting / changing the color sample presented in the color designation unit 101 is performed so that only the color in the designated color mode can be designated. The color mode definition unit 19 is used when the user wants to define his or her own color mode. The defined color mode is passed to and held in the color table holding unit 17. The coloring knowledge holding unit 16 is not static data such as a color table, but is used to hold knowledge about dynamic changes such that the colors that can be specified must be limited depending on the state of the coloring target. When the user wants to define the coloring knowledge, the coloring knowledge definition unit is used. The defined coloring knowledge is passed to and held by the coloring knowledge holding unit. Hereinafter, each component will be described in detail.

<Color Mode Designating Section 18> The color mode designating section 18 has a function of allowing the user to select a color mode. The color mode is the image or purpose of the document. For example, the type of document (OHP, report, paper, technical document, etc.), the color image of the document to be created (casual look, pastel tone, formal, etc.), creation The target of the document (for men, women, technical jobs, sales jobs, etc.). FIG. 3 shows an example of the property sheet of the color mode designation unit 18. As for the color mode, each mode may be selectable exclusively, but it is also possible to select a plurality of modes. In the case of FIG. 3, the document type is OHP, the image is formal, the target person is not specified, and the user definition is not used. In the case of the configuration using the coloring knowledge, it is further set here whether to use the coloring knowledge. In the case of the present embodiment, since the coloring knowledge is used, a portion for selecting whether to use the function is added to the property sheet (FIG. 3A). When applying coloring knowledge is selected, whether or not to apply it may be specified for each piece of knowledge held in the coloring knowledge holding unit (FIG. 3 (b)).

<Color Table Holding Unit 17> The color table holding unit 17 holds a table of colors that can be used for each color mode. The color table holder 17 is shown in FIG.
An example of the table held in is shown below. The colors held in the table are not names but values such as RGB or CMY (K). In this example, each value is 0 to 1
Is an RGB value represented by 00. The color table holding unit 17 delivers the color table corresponding to the color mode designated by the color mode designation unit 18 to the color designation changing unit 14. At that time, when a plurality of modes (for example, OHP as the document type and formal as the image in the example of FIG. 3) are designated by the color mode designation unit 18, a set of color tables registered in each mode. , That is, only the color values common to a plurality of tables are collected and passed to the color designation changing unit 14 as a color table.

<Color designation changing unit 14> Color designation changing unit 14
Normally only passes the color table passed from the color table holding unit 17 to the color designation unit 101. The color designation unit 101 presents the color table passed from the color designation changing unit 14 to the user as a sample color when designating a color. When the coloring knowledge holding unit 15 is provided, the color designation unit 101 transfers the color information of the element to be colored and the surrounding elements. While referring to the information and the color table from the color table holding unit 17, the knowledge held in the coloring knowledge holding unit 15 is referred to,
The color table is changed, and the obtained result is passed to the color designation unit 101.

<Coloring Knowledge Retaining Unit 15> The coloring knowledge retaining unit 15 retains knowledge when the colors that can be designated must be limited mainly by the state of the coloring object, not static data such as a color table. Used to do. For example, when the area to be colored is large, it is preferable to use a relatively light color because it is less noticeable.
Such knowledge is retained here. The coloring knowledge may be based on the type of the constituent element of the object, the area of the object, or the color used around the object. An example of the knowledge held in the coloring knowledge holding unit 15 is shown in FIG. A knowledge name is an identifier for that knowledge,
It is used when designating whether to apply it for each knowledge in the color mode designating part. Knowledge is not based on static data such as a color table, but based on the state of the object to be colored, for example, the size of a graphic element, the color of adjacent components when they are colored, etc. Knowledge for making dynamic decisions is described. In the case of the knowledge of the area in FIG. 5, when the target element to be colored has an area (such as a graphic element or the background of a title),
If the area is a certain size or more (for example, X mm2), only the color having a certain density (luminance) or more than a certain value (for example, Y) can be designated, and if not, other colors are specified. It is the knowledge that only the color can be specified. This means that the use of a lighter color in a large area does not make the color tighter, but the use of a darker color in a small area is not conspicuous. When this knowledge is passed to the color designation changing unit 14, only the colors satisfying this condition are selected from the color table passed from the color table holding unit 17, a new color table is created, and the current color is designated. The process of using it as a specifiable color of the component to be performed is performed. In the example shown in FIG. 5, the knowledge is described in a natural language for easy understanding, but actually, it is described in a programming language or a dedicated language. Since it is possible to describe such processing in a programming language or the like with a conventional technique, the description of the internal details will be omitted in the present invention.

<Color Mode Definition Unit 19> The color mode definition unit 19 is used when the user defines a desired color mode by himself or defines a frequently used color mode. FIG. 6 shows an example of the property sheet of the color mode definition unit 19. The color mode definition unit 19 includes a color mode name and a portion that defines a color table in that mode. In the case of this example, the mode name is defined by the user by inputting a character string, and the color table is realized in the form of selecting from all the color tables that the system has. As for the part that defines the color table, in addition to such an implementation method, a method of directly specifying RGB or YMC (K) values or a method of specifying a range of RGB or YMC (K) values (for example, R is 10 To 20) or a combination thereof. Also, if the user arbitrarily selects from all the colors, the knowledge may be useless, so it is necessary to change a part of the color table already registered in the color table holding unit 17. May be implemented in any format. The mode name and color table data defined by the color mode definition unit 19 are transferred to the color table storage unit 17 and stored therein, and can be specified by the color mode specification unit 18.

<Coloring Knowledge Defining Unit 16> The coloring knowledge defining unit 16 is used by the user to define knowledge for dynamically changing the color table. The coloring knowledge definition unit 16 defines knowledge names and knowledge, and the defined knowledge is transferred to and held by the coloring knowledge holding unit 15. Figure 7
An example of the property sheet of the coloring knowledge definition unit 16 is shown in FIG. The knowledge name is defined by the user entering a character string. Knowledge is realized here in a way that is defined using a simple programming language style. The example of FIG. 7 describes the knowledge that if the area of the target element is large, a color with high luminance is used, and if not, a color with low luminance is used. This knowledge: if (S <20) then (R> 50) or (G> 50) or (B>50); else (R <= 50) and (G <= 50) and (G <= 50). Each of R, G, and B in; means the RGB values of the color, and when (S <20), the color value that satisfies the expression after then, and when not (S <20), els
This means that only color values that satisfy the expression after e can be selected. S has a role like a reserved variable provided by the system, and the area of the target component is substituted (in this example, the unit is mm ² ). In addition to these, reserved variables mean line lengths, types of target components, attributes of each target component (character (alphabet, font, font,
Size, etc., graphic elements (lines, line types, rectangles, circles, areas,
Radius etc.) etc. Therefore, the knowledge of this example is expressed in words: "When the area of the target component is less than 20 mm ² , one of R, G, and B has a color of more than 50, and when it is 20 mm ² or more, R, Each of the G and B values must be 50 or less ”.

Kind of Coloring Knowledge and Its Structure The knowledge about coloring that can be used in this embodiment will be described in detail. There are two types of knowledge about coloring. One is a static one held in the color table, and the other is the current coloring situation and the state of the components of the document currently being colored,
It is a dynamic one that further limits the data in the color table. In the present embodiment, the former is held in the color table holding unit 17, and the latter is held in the coloring knowledge holding unit 15. To briefly describe a concrete method of realizing these, the color table holding unit 17 holds a color table for each color mode, and the coloring knowledge holding unit 15 stores knowledge for each knowledge and the internal representation of the color "For determining whether or not the condition of knowledge is satisfied"
It is realized in the form of holding in the form of “expression.” However, it goes without saying that each realizing method is not restricted to this. For example, in the embodiment, each color mode is realized in the form of a color table. However, this may be expressed using an expression as in the coloring knowledge holding unit 15.

A summary of each coloring knowledge is as follows. (1) Color mode knowledge The following are possible types of color mode and their knowledge. a) Types of documents to be created (a) OHP OHPs tend to look better when projected with a color with a higher density than when printed on paper (of course, if it is too dark, it will be dark. ). (B) Reports / Papers Reports / Papers use blue, green, and gray lines, and red, yellow, and purple lines are not suitable. b) Color image (a) Formal Formal, blue or gray system is used. (B) Pastel color Pastel color is a relatively light color with different hues. (C) Casual style In casual style, the hue is richer than in formal,
Uses a darker color than pastel. (D) Seasonal feeling Seasonal feeling is a coloring method that mainly uses colors that represent the season. For example, spring-green system or cherry color system, summer-blue system, autumn-red system, winter-grey system. c) Targets of documents to be created (a) Men / women Men tend to prefer colors such as blue and gray, and women tend to prefer pastel colors. (B) Age Documents with higher density and contrast are preferred as the age increases. (C) Sales / Technologists While sales prefer relatively brown shades, engineers prefer blue shades. (D) Tokyo / Osaka Tokyo is highly evaluated for grayish and light colors, but Osaka is clearly Darker colors are preferred.

(2) Dynamically applied coloring knowledge The following kinds of coloring knowledge can be considered as this kind of coloring knowledge. a) Items related to the types of constituent elements (a) Characters Characters use a darker color than graphic elements (lighter makes it harder to read). In addition, a lighter color is used as the font size increases. (B) Graphic elements (fill in closed areas) Use relatively light colors to color graphic elements that have an area. (C) Graphic element (solid line) A thick line uses a lighter color than a thin line. (D) Graphic element (dotted line) If the line has the same thickness as the solid line, use a darker color. b) Related to the area of the component (a) Wideness of area As the area of the component to be colored becomes lighter, it is less dull to use a lighter color, so the wider the area becomes, the lighter the area becomes. Use color. c) Regarding the colors specified around the component to be specified (a) Prohibition of duplication Do not use the same color for coloring adjacent places.

(Embodiment 2) An embodiment of a coloring mode according to a user's coloring skill. In general, the more skilled the coloring is, the more multicolors can be used. There are many. Therefore, in this embodiment, the color is limited depending on the mode. However, even if it is limited, there are cases where the number of colors is too large for a beginner. Therefore, depending on the coloring ability of the user,
By setting a coloring mode such as beginner, intermediate, or advanced and asking the user to specify a mode, a function of limiting the number of colors that can be used in each mode is realized.

FIG. 6 shows a block diagram of this embodiment. Since the basic configuration is the same as that of the first embodiment, only the different user skill level designating unit 65 will be described. The user skill level designating unit 65 in this embodiment has three modes of "beginner level, intermediate level, and advanced level" (of course, this may be two or five). An example of the property sheet of the user skill level designating unit 65 is shown in FIG. Ask the user to specify his or her skill level regarding coloring as shown in the figure. The user skill level designating unit 65 further holds the number of usable colors for each skill level. It is shown in FIG. 7 (b). In this embodiment, the setting is set to 4 colors for the beginner, 10 colors for the intermediate, and no limitation for the advanced ("-" in the figure means no limitation).

The mode designated by the user skill level designating section 65 refers to the skill level data held in the same designating section 65 and refers to the number of usable colors according to the skill level (hereinafter referred to as skill level data). Called) and passed to the color designation changing unit 64. Then, in the color designation changing unit 64, from the color table data in the color mode designated by the color mode designating unit 67, the number of colors of the skill level data passed from the user skill level designating unit 65 is the head of the color table. And delivers it to the color designation unit 601. For example, when the color mode is “casual” and 20 colors are registered in the color table for the “casual” mode, when “beginner” is selected in the user skill level designating unit 65, the color designation changing unit 64 is selected. Then, from the head of the 20-color table for the "casual" mode, only the 4-color data is passed to the color designating unit 601. That is, in the beginner mode, only four colors can be used in any coloring mode.

At this time, the color table held by the color table holding unit 66 is generally classified and held according to hue (red system, blue system, yellow system, etc.). In other words, the order has no meaning other than "color type". Therefore, by arranging the color data in the table in the order of effective colors in the mode, the user skill level designating unit 65 can be used.
The effect of is further exerted. For example, it is assumed that there is a "pastel" mode as a color mode for designating an image. Pastel tones are relatively light colors and tend to use colors with different hues. In other words, using similar colors does not give a pastel tone. In such a case, in the color designating section 601 for designating the colors, if the display order of the colors is arranged in the similar color order (for example, sky blue, marine blue, light blue, ...
・ The way to specify colors in "pastel" is to select some colors from the beginning, some colors from the end, and some colors from the middle. You will have to choose from many places.
Therefore, by displaying the color samples in the order of different hues (for example, salmon pink, sky blue, cream yellow, mauve, ...), the color samples are selected in order from the beginning. By applying coloring, it becomes possible to perform natural "pastel-like" coloring. In this order, the color table holding unit 6
If 6 holds color data, the user skill level designating section 65 can select only the most effective color from the beginning and present it to the user, so that more effective support can be provided.

Needless to say, the method of storing color data in such an order is effective even if it is not used simultaneously with the user skill level designating section. This is because a large amount of color data is given a color priority order, which serves as a guide for the user to perform coloring.

[0028]

As described above, according to the present invention, when the color of the constituent element is designated, the user is requested to designate the color mode of the document (the image of the document, the purpose, etc.) in advance, and according to the color mode. Since the colors that can be designated to the constituent elements of the document such as characters and graphic elements are limited, it is possible to guide the user in coloring and editing, and it is possible to create a document with appropriate coloring. The present invention is
It is also useful for post-editing a document that has been colored by a conventional document processing device for automatically coloring.
