Description

  The present invention relates to a colored drawing creation apparatus, method, and program for coloring various types of drawings such as maps, sketches, and bird's-eye views.

  Since drawings such as maps, sketches, and bird's-eye views are generally drawn as line diagrams in many cases, the drawn parts are color-coded to make them easy to see. In recent years, such drawing data has been drawn using a computer, and accordingly, drawing displayed on the computer has been colored. For example, Patent Document 1 describes that a drawn topographic map is colored based on a contour line corresponding to an altitude. Further, Patent Document 2 describes that a paint process corresponding to the public object type of the attribute information added to the land parcel is performed on the land parcel portion of the graphic information.

In addition, as a method for creating such a color image on a computer, a color image is created by creating a plurality of image layers and superimposing the images of these image layers (see Patent Document 3). ). In each image layer, an appropriate area can be drawn with a closed curve or a closed polygon, and the area can be colored with an arbitrary color. In addition, appropriate areas can be divided into a plurality of layers and set as partial areas, each partial area can be arbitrarily colored, and the brightness and darkness and density of the colored color, the thickness and type of lines can be set as appropriate. It is also possible to combine the processed partial areas and color them.
Republished Patent 2003/090184 JP 2001-357177 A Japanese Patent Laid-Open No. 10-134171

  In Patent Documents 1 and 2 described above, since coloring is basically performed in a single color display, it is assumed that colors are classified according to various categories such as rivers, mountains, roads, residential areas, commercial areas, paddy fields, and fields. It has not been. In other words, the above-described color coding of the drawings has various methods depending on the application, and does not correspond to such a wide application.

  Further, when color classification is performed using a single color, it becomes very difficult to see as the number of colors increases as the classification is subdivided. Therefore, in order to make it easier to see, it may be possible to color by setting a pattern or tone that recalls such a division, but to use such a method on a computer, it is necessary to acquire graphic software. However, it takes time to learn such software, and how to color design patterns and colors to make it easier to see is not something that can be learned overnight because it requires talent and experience.

  For example, when creating a pattern with complex shading and multiple colors, it is necessary to overlay a single color multiple times, and it is not possible to combine which colors and how to combine them without considerable skill and ability. . In addition, it is possible to paste in an arbitrary area by cutting and pasting using an image created in advance, but in order to apply an image cut out to an arbitrary area, it is necessary to modify the cut image Therefore, it takes a considerable amount of time for the operation skill and trial and error. In addition, there is a method such as texture mapping that develops a pre-prepared image pattern and colors a predetermined area, but a pattern that simply develops the image pattern has a strong geometric impression, and textures other than those patterns In order to create a pattern with a certain amount of skill, it is necessary to have skill and talent.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a coloring drawing creation apparatus, method, and program capable of easily performing coloring according to a drawing division using a computer and using various pattern images. To do.

  An apparatus for creating a colored drawing according to the present invention includes image storage means for storing base diagram information and colored image information for coloring the base diagram information, and setting the base diagram information in a predetermined display area to set a base layer.

Further, the drawing generating means transmits colored image information transmitted through another colored layer within a range that is not transmitted by mask information of an arbitrary colored layer. Further, the coloring editing means adjusts the transparency of the mask information in the selection range. Furthermore, the coloring setting means adds texture information that gives a predetermined texture to the colored image information. Further, it is characterized in that the colored image information portion of the colored drawing generated by the drawing generating means is synthesized and stored as colored image information.

  A coloring drawing creation method according to the present invention is a coloring drawing creation method for coloring base drawing information with coloring image information using a computer, and sets the base drawing information in a predetermined display area to create a base layer. The selected colored image information is set in the display area and mask information for making the colored image information opaque is added to create a colored layer, and the colored image information in the selected range of the colored layer is The mask information is changed to be transparent and the display state of the colored image information of the colored layer is changed independently of the mask information to adjust the display state in the selection range, and the base of the base layer A colored drawing is generated by superimposing the colored image information transmitted through a plurality of the colored layers on the figure information.

  A program according to the present invention is a program for causing a coloring drawing creation device to color the base drawing information using the stored coloring image information, and the coloring drawing creation device stores the base drawing information in a predetermined manner. Means for creating a base layer by setting in a display area, means for creating a colored layer by adding mask information that sets the selected colored image information in the display area and makes the colored image information opaque The selection is performed by changing the mask information so as to transmit the colored image information in the selection range of the colored layer and changing the display state of the colored image information of the colored layer independently of the mask information. Means for adjusting a display state in a range, and superimposing the colored image information transmitted through a plurality of the colored layers on the basic diagram information of the basic layer Allowed means for generating a colored drawing, to function as a.

  Since the present invention has the above-described configuration, the base layer information is set in a predetermined display area to create a base layer, the selected colored image information is set in the display area, and the colored image Create a colored layer by adding mask information that makes information non-transparent, and change the mask information in the range selected by the user to be transparent while the two layers are overlaid. A colored image can be displayed according to the color, and coloring according to the classification can be performed with a simple operation. In this case, as for the colored image, anyone who stores and uses a pattern image created in advance by an expert can color the selected section of the base map with a beautiful pattern image. For example, if a plurality of color images drawn by experts such as painters and designers are registered as colored images, the user can select a desired colored image and perform coloring. For example, in the case of a mountain or river, a colored image created using an image of a forest or river flow may be used. In the case of a house sketch, a planting image or a car image of a parking lot may be colored. An image may be used. In this way, it is preferable to register a plurality of types of images according to the application.

  Hereinafter, embodiments according to the present invention will be described in detail. The embodiments described below are preferable specific examples for carrying out the present invention, and thus various technical limitations are made. However, the present invention is particularly limited in the following description. Unless otherwise specified, the present invention is not limited to these forms.

  FIG. 1 shows a system configuration diagram relating to an embodiment of the present invention. A coloring drawing creation apparatus 1 operates a coloring drawing creation program 100 installed as application software on a known computer to realize its function. The The basic configuration of the computer is a well-known computer, a CPU 10 that processes logical operations, a RAM 11 that temporarily stores data and programs necessary for logical operations, a ROM 12 that stores programs and the like for executing logical operations, and applications A storage unit 13 for storing software and various types of image information, a display 14 for displaying processing results, a printer 15 for outputting processing results, and an input unit 16 for inputting data and commands necessary for processing are provided. The bus 17 is used for data transmission / reception.

  FIG. 2 is an explanatory diagram relating to a coloring process realized by the colored drawing creating apparatus 1. A plurality of colored layers CL1, CL2,... CLn are created for a base layer BL that displays a white map as a base map to be colored, and these are overlapped to perform a coloring process. 3 shows a blank map of the base layer BL used in this example (FIG. 3A), a colored image C1 of the colored layer CL1 (FIG. 3B), and a colored image C2 of the colored layer CL2 (FIG. 3C). Is shown.

  The colored layer CL1 includes a colored image C1 and mask information M1, and the colored image C1 is selected from a plurality of previously stored colored images. As these colored images, paintings drawn by experts such as painters and designers may be stored as image information in, for example, the BMP format or the JPG format. In the case of a picture hand-drawn on paper or the like, it may be read by a scanner and converted into electronic data, or an image created by graphic software may be used. The mask information M1 is information for making the colored image C1 opaque, and is set for each pixel. The opaque level can be set to an appropriate value from 100% to 0% transmittance. The other colored layers are also composed of the selected colored image information and mask information.

  In the initial state in which the coloring layer is set, the coloring image information is not displayed by the mask information, so that the coloring image does not appear even if it is superimposed on the base layer. Next, the coloring layer is edited by operating the mouse or the like.

  First, the transmittance is changed by setting a selection range in the mask information according to the classification of the blank map displayed on the base layer BL. When setting a selection range, a predetermined closed area is drawn and selected in the display area of the color image information, and the mask information of the selected range is set to 100% transmittance to display the color image in the selection range. Can be made. The selection range may be drawn so as to be applied with a brush by a so-called brush function, and the mask information of an area having a predetermined width may be set to 100% transmittance. When the brush function is used, the transmittance of the drawn peripheral portion of the predetermined width is set so as to gradually decrease, and the peripheral portion of the selected range is displayed in a state where the colored image is blurred. The operator only has to select an area for displaying the colored image with a mouse or the like while viewing the map displayed on the base layer, and can easily and accurately perform the coloring operation on the map section. .

  FIG. 4 is an explanatory diagram relating to processing for selecting a part of mask information and displaying a colored image. In the coloring layer CL1, a closed region is set so as to enclose a section related to a mountain of a map displayed in the base layer BL, or the selection ranges R11 and R12 of the mask information M1 selected by performing a painting operation with a brush function. A colored image C1 appears. In the coloring layer CL2, the coloring image C2 appears in the selection range R21 of the mask information M2 selected by performing the same operation as that of the coloring layer CL1 for the section related to the urban area of the map. For other sections of the map, a colored layer is created and a range corresponding to the section is selected to display a colored image.

  Next, the display state of the colored image information is changed. The display state is changed independently of the mask information, and known image adjustments such as rotation, movement, enlargement / reduction, density, saturation, chromaticity, brightness, and contrast of the colored image are performed. By performing such a change process, the user can freely adjust the colored image displayed in the selection range. FIG. 5 is an explanatory diagram illustrating an example of a color image changing process. In this example, a part of the mask information M of the coloring layer CL is selected to set the selection range R, and the transmittance in the selection range R becomes 100% so that the colored image C appears. (See FIG. 5 (a)). Then, the colored image C is rotated and reduced to adjust the colored image that appears in the selection range R (see FIG. 5B). In that case, the positional relationship between the mask information and the base layer BL is fixed and is not changed together with the colored image. In this way, the user can freely change the colored image displayed in the selection range according to the use and preference, and perform the coloring process of various shades. That is, the user can intuitively perform the coloring process by moving or rotating the colored image by the operation of the mouse or the like with respect to the selection range set by transmitting the mask information. It becomes possible.

  FIG. 6 is an explanatory diagram relating to processing for displaying the base layer BL and the colored layers CL1 and CL2 in an overlapping manner. In the base layer BL, a white background portion other than the outline portion of the white map is set so that a colored image of the colored layer appears with a transmittance of 100%. In the mask information of the colored layer CL1, the colored image C1 is opaque in the region of the transmittance of 0% other than the selection ranges R11 and R12, but the colored images of the other colored layers are transmitted with the transmittance of 100%. It has become. Similarly, in the other colored layer, in the region of 0% transmittance other than the selected range, the colored image of the colored layer is opaque and the colored images of the other colored layers are transmitted.

  Such display processing of the colored layer is performed, for example, when the mask information is set to “1” for a transmittance of 0% and “0” for a transmittance other than 0%, and a plurality of colored layers are overlapped. Performs processing to multiply the values. If there is a colored layer in which a transmittance other than 0% is set, the processing result is “0” for the pixel in that portion, and a colored image of the colored layer is displayed. In addition, the processing result is “1” in the pixel of the portion where the transmittance of all the colored layers is 0%, and the colored image is not displayed, and is displayed with a white background.

  FIG. 7 is a schematic view showing an image of a colored drawing in which the base layer BL and the colored layers CL1 and CL2 are superimposed and synthesized. Color processing by the colored image C1 expressed in the selection ranges R11 and R12 is performed on the mountain division on the white map displayed in the base layer BL, and coloring processing by the coloring image C2 expressed in the selection range R21 is performed on the urban district division A colored drawing consisting of a composite image can be obtained, and a colored layer can be created by selecting an appropriate colored image other than those subjected to the coloring process, and the coloring process can be easily performed. .

  A synthesized image obtained by synthesizing only the colored image portion used for the coloring process of the colored drawing thus created may be stored and used separately as a colored image. Since the colored image used for the coloring process is an image adjusted by the user himself in the editing process of the coloring layer, if it can be used for the subsequent coloring process, it can be used as it is, and the subsequent coloring Processing operations can be performed efficiently.

  The colored layer described above is a set of a colored image and mask information. In addition to the mask information, various information that changes the image quality such as texture information that gives a texture such as fabric or canvas is added to the colored image. May be. For example, as shown in FIG. 8, if texture information T is superimposed on the colored image C and set, and the mask information M is overlapped and a selection range R is set, the image quality is changed from the selection range R according to the texture information T. The colored image C can be displayed. In this case, a plurality of types of information may be added to change the image quality.

  In order to perform the coloring process as described above, the storage unit 13 stores a base diagram and colored image information used for coloring. In addition, the CPU 10 reads the coloring drawing creation program 100 to set a base diagram in a predetermined display area and create a base layer, and display the colored image selected by the operation of the input unit 16 in the display area. A color setting function for creating a colored layer by adding mask information to the color information, and changing the mask information so as to transmit the colored image information in the selected range of the colored layer selected by the operation of the input unit 16 to color the colored layer A color editing function that adjusts the display state in the selected range by changing the display state of the image independently of the mask information, and overlaying the transparent colored image information of multiple colored layers on the base diagram of the base layer Thus, a drawing generation function for generating a colored drawing is realized. In the drawing generation function, a colored drawing is generated by transmitting colored image information that has been transmitted through another colored layer within a range that is not transmitted by mask information of an arbitrary colored layer. In the editing function, the transparency of the mask information in the selected range can be adjusted. In the color setting function, texture information that gives a predetermined texture to the color image information can be added. Further, the CPU 10 has a function of synthesizing the colored image portions of the generated colored drawing and saving them as a colored image in the storage unit 13.

  FIG. 9 is a colored drawing creation processing flow. First, a base map to be colored is selected from the base map stored in the storage unit (S100), and a base layer for displaying the base map in a predetermined display area is created (S101). Next, a colored image to be used for coloring is selected from a plurality of colored images stored in the storage unit (S102), and mask information is overlapped with the selected colored image to create a colored layer (S103). The selected colored image is set so as to overlap the same area as the display area of the base diagram. Next, the coloring layer is edited (S104). First, the selection range of the mask information is drawn corresponding to the coloring section of the base diagram, the transmittance is set to 100%, and the coloring image is displayed in the selection range. Then, the image adjustment is performed by changing the display state of the colored image displayed in the selection range, and the color editing is performed according to the usage or the preference of the user.

  When coloring in another coloring section of the base diagram, the process returns to step S102 to add a new coloring layer, and the coloring layer creation and editing process is repeated. After all the colored layers have been created and edited, the base drawing and the colored layer are displayed in an overlapping manner, and the mutual adjustment of the colored layers is performed (S106). The contour shape of the selection range of the mask information is adjusted in order to match the boundary portion of the coloring layer. For example, as shown in FIG. 10, a colored layer C1 (FIG. 10 (a)) in which a selected portion SR1 having a transmittance of 50% is set at the periphery of the selection range R1 of the mask information M1 and the periphery of the mask M2 selection range R2 When the colored layer C2 (FIG. 10B) in which the selected portion SR2 having a transmittance of 50% is set is superimposed on the portion, if the priority of the colored layer C1 is high, a colored image expressed from the selection range R1 is displayed. The selected portion SR1 is displayed with priority, and since the transmittance is set to 50%, it is displayed overlapping with the colored image displayed in the selection range R2. In this way, by displaying the colored images overlappingly at the boundary portion between the two colored layers, it is possible to perform a coloring process in which the two colored images are mixed and blurred in the boundary portion to naturally shift. The coloring process of the boundary part can be finely adjusted by changing the transmittance of the boundary part of the selection range of the coloring layer having a high priority or changing the priority of the adjacent coloring layer.

  After making the overall adjustment to the colored drawing, the images of the base layer and the colored layer are combined to complete the colored drawing and output by the printer (S107). Then, the coloring result image of the colored drawing is stored in the storage unit as a new colored image (S108), and the coloring process is ended.

  FIG. 11 is an example of a process display screen for performing the coloring process described above. In the center of the display screen, an area W1 for displaying the coloring process result is set. On the right side, a list of base layers and coloring layers is displayed in the set area W2. Is displayed to be placed. Then, a layer to be edited is selected to be in an active state, and an editing operation is performed. An area W3 for displaying a list of brush functions for setting a selection range of mask information is set at the upper part of the area W2, and a menu bar W4 for changing the color image is set at the upper part of the display screen. . On the left side of the screen, an area W5 for displaying a list of tools for drawing a mask information selection range and an area W6 for displaying a tool for adjusting the display state in the area W1 are set. By using such a processing display screen, a coloring process can be easily performed by operating a mouse or the like.

  For example, by selecting a drawing tool in the region W5, drawing a rectangle, drawing a closed polygon by specifying a plurality of vertices, drawing an arbitrary closed curve with a pen tool, etc. can be performed. The range can be set freely. Further, by using the brush function of the region W3, the transparency of the boundary portion described with reference to FIG. 10 can be freely set, and processing can be performed so as to reduce the sense of incongruity of the overlapping portions of adjacent colored images. It becomes. In the colored layer list in the region W2, it is also possible to change the priority order of the colored layers and set display / non-display of the colored layers. Can be easily performed.

  In the example described above, a white map is displayed on the base layer. However, in the case of such a topographic map such as a white map or survey map, a design map based on the development / construction plan is superimposed on the current survey map in the development area. It is effective in creating a so-called colored perspective diagram when creating a completed forecast map. Since these drawings are created as explanatory materials for the surrounding residents, they are particularly effective when coloring structures such as parks, buildings, roads, sabo dams, and flow paths in an easy-to-understand manner. In addition, in the case of a sketch of a residential area, it is also effective to create a material that explains the image at the time of new construction or reconstruction by coloring residences, gardens, planting, carports, roads, etc. in an easy-to-understand manner.

  In addition to this, if the design of clothing is taken in by taking in the design of the fabric, if the fabric design is photographed with a digital camera etc. and registered as a colored image, the outline of the design of the clothing etc. in the base diagram The fabric design can be easily overlapped and its position adjustment (rotation and movement) can be easily operated. Similarly, for the design of entertainment products such as toys and household goods such as tableware, various design simulations can be easily performed by setting the outline design of the product on the base drawing and overlaying various designs and patterns as colored images. It can be carried out.
