Abstract

PROBLEM TO BE SOLVED: To convert the color of material data expressed in color while having a sense of unity and maintaining the expression effect of emphasis.
An object information acquisition unit acquires an RGB value of an object of a slide. Each emphasis target determining unit 16 calculates the average value of the RGB values of the object, extracts the object having the minimum RGB average value, calculates the ratio to all elements, and the ratio of the extracted elements exceeds a predetermined value If not, the emphasized component value is determined from the minimum value. The color application determining unit 18 takes out the object of the slide 2 and determines that it is an emphasized part if the RGB average value is equal to or less than the emphasized part value. The color application unit 19 converts the background of the highlight component object to the highlight color specified in the color palette, converts the character to the character color associated with the highlight color, and sets the background of the object other than the highlight component to the background of the base color. The character is converted to the character color associated with the base color.

Description

  The present invention relates to a process for converting the color of an element constituting material data such as a document or slide expressed in color.

  Documents such as proposals and materials created using a computer and materials such as slides (hereinafter simply referred to as “material data”) are premised on color representation. Colored document data can be easily created by a computer data creation processing program. Therefore, there is a tendency that many colors are used for the data. In addition, since it is up to the creator to decide which color to use for which element of the document data, it is easily influenced by the creator's thoughts and preferences.

  Furthermore, the material data can be stored in a computer data storage device and reused. For this reason, new document data is often created by combining various document data with different creators, creation dates and places. In the document data created by diverting the original document data as it is, the color usage may vary and the sense of unity of color arrangement may be impaired. Also, too many colors may be used, making it difficult to see.

  Therefore, in order to make it easier to see the data data for multi-color usage, there is a high awareness of color schemes, such as specifying the range of colors to be used or considering the color balance by reducing the number of colors.

As a conventional technology that supports document creation in consideration of color schemes, a standard color is specified, and either the lightness or saturation of the color in the document is changed according to the saturation or lightness of the reference color. There is known a color arrangement process in which color conversion is performed so as to achieve a harmonized color arrangement (Patent Document 1).
JP 2006-081104 A

  When creating document data that is expressed in color, it is necessary not only to consider a uniform color scheme as a whole, but also to emphasize the parts to be emphasized appropriately. It is a general expression technique to change the color of only an important part so that it can be easily grasped. However, if the proportion of the emphasized part is too large, the distinction between the emphasized part and other parts is possible. The effect of emphasis is lost. For example, it is recognized as an empirical rule that the emphasized portion can give an impression most effectively when the ratio is about 10% to 15% of the listable range.

  Therefore, it is necessary to create material data that can be emphasized in consideration of the ratio between the emphasized part and the normal part, as well as a unified color scheme.

  Conventionally, the creator manually specifies the color to be applied to the element, or once the data is displayed in grayscale, the user specifies the color to be applied based on the grayscale. Had gone. In particular, when a large amount of material data is created by multiple persons, it is up to the creator to determine the part to be emphasized and the color to be applied to the part to be emphasized. The color setting environment was not always the same, and it was more difficult to make a unified judgment throughout.

  In the technique of the above-mentioned Patent Document 1, a plurality of colors for generating color by changing the saturation or lightness according to the brightness or saturation value of the reference color specified by the user are generated, and the generated colors and the reference are generated. A range in which the brightness contrast with the color is large is used as the brightness value range of the emphasized portion, and converted colors are generated for the number of colors of the emphasized portion specified by the user. For this reason, a uniform color scheme based on the reference color can be performed. However, the emphasis portion is only color-converted using a color having a high brightness value contrast, and color conversion considering the expression effect of the emphasis portion cannot be performed.

  In addition, when the text data such as words and phrases with different colors were emphasized in the document data, judgment by brightness and saturation could not be made, and appropriate color conversion could not be performed.

  In addition, when a graphic element including characters is emphasized, only the background color of the element is converted, and the character color that overlaps the background in the element is not converted, which may make it difficult to see the character.

  An object of the present invention is to realize a color conversion process for document data in which colors having a sense of unity as a whole are applied and the emphasis expression effect is maintained.

  The present invention is a color conversion processing program for causing a computer to execute color conversion processing for converting the colors of elements constituting material data to be expressed in color, and performs the following processing.

  A computer that executes the present invention holds a color palette composed of a plurality of similar colors used as background colors of elements and character colors associated with the respective colors.

  Then, the RGB value of each element of the material data to be subjected to color conversion is acquired. The average value of each RGB value of each element is calculated, the element having the minimum RGB average value is extracted, the ratio between the extracted element and all elements is calculated, and the ratio of the extracted element does not exceed a predetermined value In this case, the emphasized component value is determined based on the minimum value.

  Then, the elements of the material data are taken out one by one, and when the RGB average value is equal to or less than the emphasized part value, the element is determined as the emphasized part. As for the emphasis component, the background is converted to the emphasis color specified in the color palette, and the character is converted to the character color associated with the emphasis color. For the elements other than the emphasis part, the background is converted to the background color of the base color, and the character is converted to the character color associated with the base color.

  Through this process, the data selected from the specified color palette is applied to the elements that make up the document data, creating a sense of unity, and supporting the document data creation process that effectively expresses the part you want to emphasize can do.

  In particular, elements that are emphasized in the data to be processed are judged to be emphasized parts only when they appear at an appropriate ratio within a predetermined range, such as slides and pages. No highlight color is applied. Therefore, it is possible to make the creator aware of the excessive emphasis and give the opportunity to correct the emphasis expression appropriately.

  Furthermore, since the character color is set in association with the background color of the element in the color palette, the background of the highlighted part and the color of the character can be converted in an appropriate contrast. Can be difficult to see.

  In the present invention, in the emphasized part specifying process, a second emphasized part value having a value larger than the emphasized part value is determined from the minimum value. In the color application process, An element having an average value equal to or smaller than the second emphasized component value is determined as a semi-emphasized component, and the semi-emphasized component can be color-converted using a color brighter than the emphasized color included in the color palette. This makes it possible to perform color conversion that retains multi-level emphasized expressions.

  In the present invention, the element information acquisition process acquires the character color and font of the document data, and the emphasized part identification process determines the number of appearances of the acquired character color / font as the character color / font. The character color / font in which the ratio of the number of character appearances to the total number of characters does not exceed a predetermined value and the number of appearance characters is the smallest is determined as the emphasized character color / enhanced font. Of the characters in the document data, the character corresponding to the emphasis character color / enhancement font is determined as the emphasis character, the emphasis character color is converted to the predetermined character color, or the element including the emphasis character is identified as the emphasis component and emphasis The background of the part and the color of the characters can be converted to the emphasized color.

  As a result, when the words (characters) emphasized by the character color or font are emphasized at an appropriate ratio, the emphasis expression for these emphasized words can be appropriately retained. .

  Further, according to the present invention, among the elements of the document data, elements having the same RGB value, or elements or characters designated by the user are set as non-conversion targets, and are set as non-conversion targets in the color application process. The RGB value of the selected element can be held as it is.

  As a result, it is possible to realize a flexible color conversion process by excluding colors such as gray elements having the same RGB values or elements specified by the user from the color conversion.

  The reason why the elements having the same RGB values (gray colors) are not converted is that the RGB values are balanced and can be harmonized with any color.

  Furthermore, as another aspect, the present invention may be a processing apparatus including a processing unit that realizes the above-described processing, or a processing method including the above-described processing steps performed by a computer.

  The program according to the present invention can be stored in an appropriate recording medium such as a portable medium memory, a semiconductor memory, or a hard disk that can be read by a computer. It is provided by transmission and reception using various communication networks via the interface.

  According to the present invention, the colors of elements and characters constituting the document data are not only collectively converted using the color selected by the user from the color palette, but also the elements emphasized in the document data are identified. The emphasized expression can be maintained even after the color conversion process.

  In particular, only when an element is emphasized at an appropriate ratio within a predetermined range, the element is color-converted with an emphasized color, so that the ratio of the emphasized part can be noticed by the creator, and the effect of the emphasized expression It is possible to support document data creation work in consideration of

  In addition, since elements that are not subject to color conversion processing can be specified by the user, it is possible to deal with flexible emphasis expression.

  As described above, since the color conversion processing of the emphasized portion, which has been conventionally performed manually, can be automated, it is possible to reduce the burden of document data creation work and easily create good-looking document data.

  FIG. 1 is a diagram showing a configuration example in the best mode for carrying out the present invention.

  The color conversion processing apparatus 1 according to the present invention converts the colors of elements and characters (hereinafter referred to as objects) constituting the slide 2 as the material data using colors of a color palette provided in advance, and the processing result Is a device that outputs a processed slide 2 ′.

  In this embodiment, the object to be processed is character data and graphic data including characters, not image data such as photographs. Further, the emphasis expression for an object is made into two stages, and the object to be emphasized most is an emphasis part, and the object to be emphasized next is a semi-emphasis part.

  FIG. 2 is a diagram illustrating an example of an appropriate ratio with respect to the entire emphasized parts and semi-emphasized parts.

  In this example, if the number of objects to which dark colors are applied for emphasis in the slide 2 before processing is 15% of the total number of objects, these objects are identified as emphasis parts. , The “enhancement color” for the emphasis part prepared in the color palette is applied. By limiting the emphasized parts to about 10% to 15%, it is possible to clarify what is being claimed.

  Further, when the number of objects to which the dark color is applied next to the highlight component is 20% of the total number of objects, the semi-emphasis component is specified as the semi-emphasis component and prepared in the color palette. Color "is applied. The reason for suppressing the semi-emphasized parts to about 20% of the whole is that if the expression that is slightly emphasized is used a lot, the point to be emphasized becomes unclear.

  It should be noted that the base color is applied to the objects other than the emphasized part or the semi-emphasized part as the non-emphasized part.

  FIG. 3 is a diagram illustrating an example of a color palette.

  A color group (for example, blue, green, etc.) composed of similar colors is set in the color palette. Each color group defines multiple colors with different brightness. As the colors, “enhanced bright and dark colors (emphasized colors)” suitable for the background color of the emphasized parts and “slightly emphasized bright and dark colors (semi-emphasized colors)” suitable for the background colors of the semi-emphasized parts are prepared. The emphasis color and the semi-enhancement color are defined in association with the character colors that are applied simultaneously.

  For example, as shown in FIG. 3, in the blue group prepared in the color palette, three bright and dark colors with different brightness and three slightly bright and dark colors are defined as emphasized colors. Also, in correspondence with the case where the original object is a gradation, an emphasis color and a semi-emphasis color in which the gradation is defined are defined. In addition, a character color (white) associated with each of the emphasized colors and a character color (black) associated with the semi-emphasized color are defined. Note that the color of the frame of the object is also defined in association with each of the emphasis color, semi-emphasis color, and base color.

  The color conversion processing device 1 is a computer including a CPU and a memory, and is configured by a software program or the like, and includes a predefined setting unit 11, a predefined storage unit 12, a color palette selection unit 13, a color palette storage unit 14, and object information. An acquisition unit 15, an emphasis target determination unit 16, an emphasis component value storage unit 17, a color application determination unit 18, and a color application unit 19 are provided.

  The predefined setting unit 11 designates an object constituting the slide 2 that is not subject to color conversion processing (non-conversion target), and stores this designation information in the predefined storage unit 12. The non-conversion target is specified based on the shape and data type of the object. As an object attribute, for example, a graphic type such as rectangle, circle, or arrow is used. Further, the pre-defined setting unit 11 sets a range as a processing unit, such as whether the processing target is a page of the slide 2 or an object selected by user designation.

  The color palette selection unit 13 selects an emphasis color to be applied to the emphasized part, a semi-enhanced color to be applied to the semi-enhanced part, etc. from the color palette as shown in FIG. 3 stored in the color palette storage unit 14.

  The object information acquisition unit 15 includes, for each object constituting the slide 2, RGB color system color information (R value, G value, B value) of the object background or characters, and character color information (R value, G value, B value) and font name are acquired.

  The emphasis target determining unit 16 determines a threshold value for specifying the object constituting the slide 2 as an emphasis part or a semi-emphasis part. Specifically, the average value of each RGB value of each object on the slide 2 is calculated, and all objects whose calculated RGB average value is the minimum value are extracted. The ratio between the number of extracted objects and the total number of objects is calculated. If the ratio of the extracted objects does not exceed a predetermined value, the emphasized component value is determined based on the minimum value. The ratio of the object having the minimum value to the total object may use not only the number of objects but also the area of the object.

  Further, when a semi-emphasized color is specified in the color palette, the semi-emphasized component value is calculated by performing the same processing as in the case of the emphasized component value.

  In addition, the number of appearances is calculated for each character color / font with respect to the characters on the slide 2. Then, for each character color / font, the ratio of the number of character appearances to the total number of characters is calculated, and the character color / font whose ratio of the number of character appearances does not exceed a predetermined value and that has the smallest number of appearance characters is highlighted character color And determined as an emphasized font.

  The emphasized part value storage unit 17 stores the emphasized part value, the semi-emphasized part value, the emphasized character color, and the emphasized font determined by the enhancement target determining unit 16.

  The color application determining unit 18 selects an object as an emphasis component when the RGB average value of the object of the slide 2 is equal to or less than the emphasis component value, and when the RGB average value exceeds the emphasis component value and is equal to or less than the quasi-emphasis component value. The object is determined as a semi-emphasized part. Further, among the characters on the slide 2, a character corresponding to either the emphasized character color or the emphasized font is determined as the emphasized character.

  The color application unit 19 converts the background color of the object determined to be an emphasis part into an emphasis color, and converts the character into a character color associated with the emphasis color. Similarly, the color conversion processing is performed on the object determined to be a semi-emphasized part. Further, the emphasis character and the object including the emphasis character are also subjected to color conversion processing as an emphasis part.

  FIG. 4 is a diagram showing a flow of conversion processing for the object of the slide 2.

  In step S1, the pre-definition setting unit 11 of the color conversion processing device 1 sets, as a pre-definition, the type of an object to be non-converted that is not subjected to color conversion processing, based on the designation input by the user.

  In step S2, the color palette selection unit 13 selects a color group, an emphasis color, a base color, and the like to be applied to the object from the color palette stored in the color palette storage unit 14.

  In step S3, the predefined setting unit 11 selects a unit to be processed. For example, a slide / page unit or an object group selected by the user.

  In step S4, the object information acquisition unit 15 reads the data of the slide 2 and acquires RGB values as the color information of each object. Get the character color and font of each character.

  In step S5, the emphasis target determining unit 16 calculates the average value of the RGB values of the objects, extracts the objects having the minimum RGB average value, calculates the ratio between the number of extracted objects and the total number of objects, and extracts them. If the ratio of the number of objects to the total number of objects is 10% or less, the emphasized component value is calculated from the minimum value. For example, a value obtained by increasing the minimum value by 5% is set as the emphasized component value.

  If necessary, a semi-emphasized part value is calculated by the same process.

  Also, the number of appearances of characters is calculated for each character color, and the ratio between the number of appearances of each character color and the total number of characters is calculated. Then, the character color in which the ratio of the number of character appearances does not exceed a predetermined value and the smallest number of appearance character characters is determined as the emphasized character color. Similarly, the number of character appearances is calculated for each font, the ratio to the total number of characters is calculated, and a font whose ratio of the number of character appearances does not exceed a predetermined value is determined as an emphasized font.

  In step S6, color conversion processing is started for all objects on the slide 2, and the color application determination unit 18 repeats the processing in steps S7 to S12 for the number of objects (step S13), and ends the processing.

  First, in step S7, the color information of the object of the slide 2 held by the object information acquisition unit 15 is acquired.

  In step S8, a range to be applied to the object is determined. That is, it is determined whether the object corresponds to an emphasized part or a semi-emphasized part, or whether the character corresponds to an emphasized character color or an emphasized font. If the RGB average value of the object is equal to or less than the emphasized component value, it is determined as an emphasized component. Further, if the character or the character of the object corresponds to either the emphasized character color or the emphasized font, it is determined as an emphasized part.

  If the application range is an emphasis component (step S9), the object color is converted with the emphasis color selected from the color palette (step S10).

  If the object character corresponds to the emphasis character color or the emphasis font, and the object background color is white, black, or gray, the character is subjected to predetermined modification processing, for example, bold, underline, etc. .

  If the application range is a semi-emphasized part (step S9), the object color is converted with a semi-emphasized color (step S11).

  If the application range is neither an emphasis component or a semi-emphasis component, that is, if it is a key component (step S9), the color of the object is converted with the key color (step S12).

  The above processing is repeated for the number of objects (step S13), and by performing color conversion of all the objects, the objects on the slide 2 are expressed using the color group specified in the color palette, and the emphasized objects are slightly emphasized. Representation is also maintained as it is.

  5 to 8 are diagrams showing specific examples of object color conversion processing.

  FIG. 5 is a diagram illustrating an example of the slide 2 to be processed. The slide 2 in FIG. 5 includes seven objects (ob1 to ob7). FIG. 6 is a diagram showing the RGB values of the background color and the character color of each object (ob1 to ob7) on the slide 2 in FIG. The background color and text color of each object are set as follows.

Background color of object ob1 = light green to white gradation, character color = black;
Background color of object ob2 = light gray, character color = black;
Background color of object ob3 = light gray, character color = black;
Background color of object ob4 = dark pink, character color = black;
Background color of object ob5 = light gray blue, character color = black;
Background color of object ob6 = light gray blue, character color = black;
Background color of object ob7 = dark yellow, character color = dark red;
Further, in the color palette shown in FIG. 3, emphasized colors (R: 26, G: 82, B: 6), semi-enhanced colors (R: 165, G: 233, B: 171), base colors from the green group. (R: 255, G: 255, B: 255) is designated. Also, as a predefined definition, assume that gray (colorless) objects are set as non-conversion objects.

  By the pre-definition, the objects ob2 and ob3 of the slide 2 are removed from the processing target. An RGB average value is calculated for each of the remaining objects ob1, ob4 to ob7, and the RGB average value (= 170) of the object ob7 is the minimum value. Accordingly, the ratio between the object ob7 and the other object is calculated, and since the predetermined ratio (for example, 15%) is not exceeded, this minimum value is set as the emphasized component value. Further, since the RGB average value (= 204) of the object ob4 is the next smallest value and does not exceed the predetermined ratio, this minimum value is set as the semi-emphasized component value.

  In the color conversion process, the RGB average value of the object on the slide 2 is compared with the above-described emphasized component value and semi-emphasized component value, and the color to be applied is determined.

  As a result, the background and characters of the object ob7 are converted to the emphasized color, the background and characters of the object ob4 are converted to the semi-emphasized color, and the objects ob5 and ob6 are converted to the base color.

  FIG. 7 is a diagram illustrating an example of the processed slide 2 ′. FIG. 8 is a diagram showing RGB values of the background color and the character color of the objects ob1 to ob7 of the processed slide 2 'of FIG.

  As shown in FIG. 5, in the slide 2 before processing, five colors (light green, light gray, dark pink, light blue, and dark yellow) having different color systems were applied. However, as shown in FIG. 7, green colors are applied to the objects ob1 to ob7 of the processed slide 2 ′, creating a sense of unity in the color application, and the objects ob7 and ob4 to be emphasized are also appropriately selected. You can see that it is expressed with emphasis.
