Description

  The present invention relates to a design support system for supporting image designers in various fields such as interiors and exteriors, but is not limited thereto. In particular, the present invention relates to the harmonization of objects in specific applicable fields such as interiors and exteriors. The present invention relates to a design support system provided with a knowledge database for color correction in consideration of the problem and providing support information to designers.

  In recent years, DTP (desktop publishing) has become very popular, and it has become available to small offices and individuals, and pamphlets, catalogs, magazines, etc. have been created using DTP. Image design is important for effectively communicating intentions.

  In addition, recently, an image taken with a digital camera or the like can be easily input on a computer, and image editing software such as Photoshop is used for trimming or tone correction, or an illustrator (Illustrator) or the like. By creating illustrations using this application, it has become possible to design images easily on software.

  Against this background, recently there has been a dramatic opportunity for general designers who do not have sufficient knowledge of computer image creation technology and modeling and color in various fields to design images. It is increasing. For example, in the fields of interior and exterior, designers (interior coordinators) create images using a computer, such as room layouts, furniture, curtains, and wallpaper, or images that are input to a computer using a digital camera or scanner It is becoming common to communicate with customers based on design images created by processing images.

  When using images created by designers as a means of communication with customers, etc., images are displayed on a display device connected to a computer, or a printed matter printed by a color printer connected to the computer is used as a medium. It will be. By the way, multiple images such as room layouts, furniture, curtains, wallpaper, floor and ceiling materials are drawn in design images in the interior and exterior fields, but the color of each object is individually specified by the designer. Will do.

  However, for general image creators, there are many selectable processes in the image creation application, so that the effect of each process cannot be fully understood and various techniques cannot be used effectively. In other words, general image creators cannot fully understand how the images they designed, photographed, and collected will give the reader an impression, and their intentions cannot be expressed by the processing performed on the software. Alternatively, the created image often gives an impression opposite to the designer's intention.

  Therefore, when deciding the color of each object, etc., expressing the designer's intention effectively, or designing the entire image so as to give a good impression to the customer is a matter of expertise in modeling and color, computer This is extremely difficult for general designers who are not familiar with image creation technology.

  As an apparatus for supporting a general designer's design work, for example, there is an image design support apparatus disclosed in Patent Document 1 below. This image design support device can give clear and detailed guidelines for designing images to general designers who do not have design knowledge. The purpose is to allow the entire image to be designed. In this image design support device, the designer, from the image database, displays a similar impression image group (an image having an impression similar to the image that he / she intends to design) and a contrast impression image group (the image opposite to the image he / she intends to design). An image having an impression) is selected.

  Then, the image analysis unit of the image design support apparatus calculates visual feature quantities such as brightness average, brightness balance, chromaticity average, cold warm color balance, and saturation average of each image. Further, the collage image creation unit of the apparatus selects two visual features having a large difference in average value of visual feature values between the similar impression image group and the contrast impression image group, and each of the similar impression image group and the contrast impression image group Is displayed on the display unit as a two-dimensional graph.

Japanese Patent Laid-Open No. 10-188023

  The image design support apparatus disclosed in Patent Document 1 arranges a design object (object) in any print region and in what position when the designer creates a pamphlet or a poster. In addition, what color scheme is appropriate depending on the arrangement position of the object is displayed as support information. For example, in the field of advertising pamphlets and poster designs, color engineering requires the position and color arrangement of objects that appeal to the viewer. For this reason, the image design support apparatus displays the arrangement and color arrangement of objects as support information for the designer.

  However, such an image design support device cannot always be effectively used depending on the image data to be created. For example, when creating images of interiors and exteriors, the objects are various interior items such as furniture and curtains and interior materials such as ceilings and floors. These are the places where the objects are placed (entrance, living room, dining kitchen) Depending on the nature of the bedroom, etc., there are general rules specialized in architectural engineering and color engineering, recommended colors, etc., and it is preferable to make each object an overall harmonious color. When the color scheme is not harmonized, there is a problem that an observer feels uncomfortable. That is, the design support apparatus disclosed in Patent Document 1 is suitable for an illustrator engaged in an advertising business and the like, and is not suitable for an interior coordinator engaged in an architectural business or the like.

  Of course, there are individual differences in color sensation, and there are motifs intended by the designers, and it does not exclude the arrangement of individual colors to individual objects, but it is a specialist in architectural engineering and color engineering. When a designer who is not familiar with knowledge creates image data for a very general observer, it is preferable that a support system based on such expertise can be provided.

  Hereinafter, specific examples of the present invention will be described in detail with reference to examples and drawings. 1 is a block diagram showing the configuration of the design support system according to the present invention, FIG. 2 is a block diagram showing the main part of the design support apparatus, FIG. 3 is a conceptual diagram showing the schematic configuration of the LUT storage means, and FIG. These are the conceptual diagrams which show schematic structure of a knowledge database.

  As shown in FIG. 1, a design support system 10 according to an embodiment of the present invention includes a design support apparatus 12 configured by a personal computer (PC) or the like, and a scanner 20 and a digital camera 30 that input image data to the design support apparatus. Printer apparatuses 70 and 80 are connected via a network 14 such as a design support apparatus LAN (Local Area Network). The design support apparatus 12 includes a printer driver 40, which processes input image data and outputs color image data to the printer 70, the image forming apparatus 80, and the like. In addition to being input to the design support apparatus 12 from the scanner 20 and the digital camera 30, the image data can also be generated on the design support apparatus 12 using various image creation applications. It may be configured to be connected to the design support apparatus 12 via the network 14.

  FIG. 2 is a diagram showing a detailed configuration of the printer driver 40 which is a main part of the design support apparatus 12. As shown in FIG. 2, the printer driver 40 of the design support apparatus 12 includes a data reception unit 41, an image feature data acquisition unit 42, a harmony correction selection unit 43, an object determination unit 45, a color adjustment unit 46, and an output image data creation unit 47. , And a data transmission unit 48.

  The data reception unit 41 receives image data created on the design support apparatus 12 or image data input from an input unit such as the scanner 20 or the digital camera 30. The image feature data acquisition unit 42 Extracting object data such as furniture, ceiling, floor, curtain, etc. from the image data received by the data receiving unit 41 and obtaining the coordinate value (position) of each object, and transferring these object data to the harmony correction selecting unit 43 It is.

  The harmony correction selection unit 43 performs a display on a display unit (not shown) that allows the designer to select whether or not to correct the object to a harmonious color. If harmony correction is not selected, the object data is output as an output image. When the harmony correction is selected, the object data is transferred to the object determination unit 45.

  When the object data is transferred to the output image data creation unit 47 without the harmony correction being selected, the output image data creation unit 47 corresponds to the standard LUT (color conversion table) and each object from the LUT storage unit 50. The acquired LUT is obtained, and the received object data is color-converted (converted into a CMYK value that is a color space for an output device such as a printer) to determine the color value of the object. The LUT storage means 50 is composed of a hard disk device (HDD), and as shown in FIG. 3, the LUT corresponding to each object used in the interior and exterior fields such as a standard LUT 52, furniture LUT 53, curtain LUT 59, etc. The group 51 is stored.

  When harmony correction is selected, the object discriminating unit 45 corresponds to the standard LUT (color conversion table) and each object from the LUT storage unit 50 according to the object data passed through the harmony correction selecting unit 43. The LUT is acquired, and the received object data is color-converted (converted to a CMYK value that is a color space for an output device such as a printer) to determine the color value of the object and transferred to the color adjustment unit 46. The color adjustment unit 46 refers to the knowledge database 60 and displays a color adjustment recommendation on a display unit (not shown) so that the color values of the objects can be harmonized.

  As shown in FIG. 4, the knowledge database 60 includes a color adjustment rule table 61 based on the nature of the zone in which the objects are arranged, and a color adjustment recommendation table 62 that stores color adjustment recommendation plans and pass / fail criteria for each object. . In the color adjustment rule table 61, each object is arranged based on the Munsell system color space and LCH color space in which colors are scaled to lightness (L: Lightness) / saturation (C: Chroma) / hue (H: Hue). The color adjustment recommendation table 62 stores the zone in which the object is arranged for each object, the color adjustment recommendation for each object, and the color value of the object. A pass / fail criterion for determining whether or not the color adjustment recommendation is met is stored based on the Munsell color space and the LCH color space.

  For example, the color adjustment rule table 61 will be described. The entrance, stairs and living zone of the building have public characteristics, the dining room and kitchen zones have semi-public characteristics, and the bedroom and other zones have private characteristics. It is considered to have personality. It is preferable that the colors of interior materials such as furniture, public zone walls, floors, and ceilings arranged in the public zone should be unified and harmonized with each other, so the maximum difference in hue (H) of the Munsell hue ring The rule of keeping 30 ° or less is registered in the color adjustment rule table 61 (see the description of Hue <30 ° in FIG. 4).

  Further, the color adjustment recommendation table 62 will be described. For each object, zone divisions (the public, semi-public, and private divisions) in which the objects are arranged are registered, and recommended colors for each object. (See FIG. 4, recommendation column of the color adjustment recommendation table 62) and pass / fail criteria for determining whether the object color value meets the recommended color condition (pass / fail) (FIG. 4, color adjustment) (Refer to the NG column of the recommendation table 62) is registered.

  For example, “entrance” belongs to the public zone, and generally a warm color is recommended. Therefore, a color between 5RP and 5Y in the Munsell hue is used as a color adjustment recommendation (see the recommendation column in the figure). And the pass / fail criterion for the color value of the “entrance” (see the NG column in the figure) avoids high-saturation colors so as to warmly accept visitors, and when the saturation value C is greater than 100 in the LCH color space, the overall harmony “C> 100 (saturation value of LCH color space)” is registered so that it is determined that the above is not achieved.

  In addition, since the “staircase” has a risk of stepping off when the lightness difference is small, “ΔL <2 (Δ is 2) so that it is determined that there is a danger when the lightness difference is“ 2 ”or less by changing the color of the step. Lightness difference between colors: LCH color space lightness L) is registered as a pass / fail criterion, and “ΔL> 5”, which is larger than the lightness difference ΔL5, is registered as a recommended proposal. Similarly, color adjustment recommendation proposals and acceptance criteria for living room walls, ceilings, floors, dining room curtains, table cloths, bedrooms, etc. are registered.

  In the above description, the color adjustment rule table 61 and the color adjustment recommendation table 62 are a knowledge database that stores color adjustment rules, color adjustment recommendations, and pass / fail criteria created using two color spaces of Munsell and LCH. However, a knowledge database using only the LCH color space can be obtained by replacing all colors of the Munsell system with the LCH color space.

  Next, normal image data creation when harmony correction is not selected by the harmony correction selection unit 43 and image data creation procedures when harmony correction is selected will be described.

Explanation of “When harmony correction is not selected”.
Input image data sent from the design support apparatus 12, the scanner 20, or the digital camera 30 is first sent to the data receiving unit 41 of the printer driver 40. Then, the data receiving unit 41 passes the received data to the image feature data acquiring unit 42, and the image feature data acquiring unit 42 cuts out object data such as a sofa, a table, a curtain, a ceiling, and a floor and obtains an object coordinate value To do. Thereafter, the object data (image data) including the extracted object data is transferred to the harmony correction selection unit 43, and the harmony correction selection unit 43 displays a selection screen on a display unit (not shown).

  When the designer makes a selection input indicating that harmony correction is not performed from an operation unit (not shown), the harmony correction selection unit 43 transfers the image data including the object data to the output data creation unit 47. The output data creation unit 47 obtains the standard LUT 51 and the LUTs such as the furniture LUT 53 and the curtain LUT 59 corresponding to each object from the LUT storage means (HDD) 50, and the transferred data is a color base for the output device. The data is converted into CMYK values and passed to the data transmission unit 48. Then, the data transmission unit 48 transmits the image data (CMYK data) received from the output data creation unit 47 to the printer 70, the image forming apparatus 80, and the like.

Explanation of “When harmony correction is selected”.
When the designer makes a selection input for harmonizing correction from an operation unit (not shown), the harmonizing correction selecting unit 43 transfers the object data to the object determining unit 45. The object discriminating unit 45 obtains the standard LUT 52 and the LUT such as the furniture LUT 53 or the curtain LUT 59 corresponding to each object from the LUT group 51 of the LUT storage means (HDD) 50, and obtains the color value of the designated color in each object. The data of the objects, the arrangement of the objects, and the color values are sent to the color adjustment unit 46. The color adjustment unit 46 refers to the color adjustment rule table 61 and the color adjustment recommendation table 62 of the knowledge database 60 in order to determine whether or not they are harmonized based on these data.

  First, it is determined in which space (zone) the object is located, and if it is found in the same registered zone, it is determined whether the object is harmonized according to the rules of the zone. For example, if the image data includes living room wall, ceiling, and floor objects, the wall object is determined to be in the “public zone” and compared with all objects registered in the public zone. Check the hue difference. If it is within the range, proceed to the next step. If it is NG according to the pass / fail criteria (does not meet the pass / fail criteria), it is corrected or a non-conforming message is added to the image data according to the specification selected by the designer.

  Also, for example, if the wall object is within the pass / fail criteria range for all objects in the public zone, it is determined whether it is in the object pass / fail criteria region (NG region), and recommended if it is non-conforming (NG). Correct the color value within the range. If the color value of the wall is brighter than the ceiling, the color value is corrected by lowering the brightness from the color of the ceiling. Then, the modified object data in which the color value of each object data is changed is transferred to the output data creation unit 47.

  The output data creation unit 47 acquires the LUT such as the furniture LUT 53 or the curtain LUT 59 corresponding to each object from the LUT storage means (HDD) 50 for the modified object data and other image data. Then, the transferred corrected object data is converted into a CMYK value that is a color base for the output device, and is passed to the data transmission unit 48. The data transmission unit 48 transmits the image data (CMYK data) received from the output data creation unit 47 to the printer 70, the image forming apparatus 80, and the like.

Description of “when a warning is issued when the entire image is not harmonized”.
Similarly to the normal processing, the input image data sent from the design support apparatus 12, the scanner 20, or the digital camera 30 is first sent to the data receiving unit 41 of the printer driver 40. Then, the data receiving unit 41 passes the received data to the image feature data acquiring unit 42, and the image feature data acquiring unit 42 cuts out object data such as a sofa, a table, a curtain, a ceiling, and a floor and obtains an object coordinate value To do. Thereafter, the image data including the extracted object data is transferred to the harmony correction selecting unit 43, and the harmony correction selecting unit 43 displays a selection screen on a display unit (not shown).

  If the designer does not make harmony correction from an operation unit (not shown) but makes a selection input to issue a warning when the designer is not in harmony, the harmony correction selection unit 43 transfers the object data to the object determination unit 45. The object determination unit 45 acquires a standard LUT 52 from the LUT storage means (HDD) 50 and a LUT such as a furniture LUT 53 or a curtain LUT 59 corresponding to each object, and the transferred data is a color base for an output device. The data is converted into CMYK values, the color value of the designated color is acquired, and the data of the objects and the arrangement of the objects and the color values are sent to the color adjustment unit 46. The color adjustment unit 46 determines whether or not harmony is achieved from the received object, the arrangement of the objects, and the color value by referring to the knowledge database 60 in the same manner as when the harmony correction is selected, and warns when the harmony is not achieved. The message is added to the image data and transferred to the output data creation unit 47.

  As described above, according to the design support system of the present invention, the position and feature data of each object are extracted from the input image data, and the mutual harmony between objects is considered for each object with reference to the knowledge database. Since it has a color adjustment unit that outputs a color adjustment recommendation, even a designer without specialized knowledge can easily correct the color of each object according to the recommendation output from the color adjustment unit. Will be able to.
