  An embodiment of the present invention will be described with reference to FIGS. This embodiment shows an example in which the present invention is applied to a color scheme simulator for a roof of a building or an outer wall.

  FIG. 3 shows an operation display screen of a simulator using a tablet terminal. A large picture of the building is displayed on the screen, and icons, operation tools, and the like necessary for operation are arranged below and to the side. The photograph of the building is taken by photographing the building on which the color scheme design is to be simulated with the tablet terminal. Of course, it is also possible to capture separately photographed pictures and separately drawn illustrations. In this case, since the color scheme design of the roof and the outer wall is simulated, it is desirable to capture an image so that the roof and the outer wall are displayed in an easy-to-view manner. The simulator may be configured by a personal computer.

  Below the building photo, simulator operation icons 21 are displayed. From the left, "Save", "Undo", "Redo", "Delete plan", "Add plan", "Layout", Icons respectively displayed as “recruitment” and “top screen” are arranged. Each icon functions as follows by touching them. “Save” saves the edited image as described later. “Undo” and “Redo” return to the previous operation screen and the subsequent operation screen. “Delete plan” and “Add plan” delete and add the color scheme design plan for the roof and outer wall. “Layout” displays part of the icons and operation tools on the simulator screen and displays the buildings in two places. One of the two pictures shows the building before the color change, and the other shows the color. The new building is displayed larger. On this display screen, based on the photograph of the building after the color change, it is possible to output a print or to arrange a sample of the coated plate. “Recruit” puts a check mark on the plan you want to adopt from the multiple plans you have designed. The “top screen” is shifted to the top screen for initial setting of the simulator. In addition, icons of arrow marks 22 and 23 are displayed at the lower left and right ends of the screen. When the icon 22 is touch-operated, the screen is moved to a screen displaying the previous plan, and when the icon 23 is touch-operated, the screen is moved to a screen displaying the next plan.

  A painting tool 30 is displayed on the upper side of the building photograph. The plan name (Plan 1 in FIG. 3) is also displayed in the upper part of the frame of the painting tool 30 so that the plan currently displayed on the screen can be understood. In the frame of the painting tool 30, icons of “draw”, “erase”, “pen thickness”, and “automatic selection area” are displayed. Each icon functions as follows by touching them. “Draw” is a tool for selecting the range to change the color scheme. After touching the pen mark placed at the top and tapping with your finger on any part of the roof or outer wall of the building photo, the automatic selection tool functions. As described later, an area within a predetermined range is selected. When an area is selected, the color of the selected area is changed to clearly indicate the selected area. At this time, the automatic selection area can be arbitrarily expanded, narrowed, or changed by sliding on the inclined frame line while touching the circle mark of the operation tool in the lower “automatic selection area” with a finger. Further, when an operation of tracing an arbitrary part of the roof or outer wall of a building photograph with a finger is performed, the area traced by the pen tool functioning is changed as a selection area. At this time, the pen thickness can be arbitrarily changed by sliding on the inclined frame line while touching the circle mark of the “pen thickness” operation tool. Tap operation mark placed at the bottom of "Draw", and after touching this mark, tap multiple times with your finger to enclose any area of the roof or outer wall of the building photo, the enclosed area will be selected The color is changed as an area. “Erase” is a tool that reduces the range selected as described above to change the color scheme. After touching the eraser mark placed at the top, use your finger to touch the color-changed area on the roof or outer wall of the building photo. When the tracing operation is performed, the color change of the traced area is canceled. The tap operation mark placed at the bottom of "Erase" is the area surrounded by touching this mark and tapping multiple times with your finger to surround the color-changed area of the roof or outer wall of the building photo. The color change is canceled.

  A layer / color selection tool 40 is displayed at the lower side of the building photo. Here, it is possible to select the part (roof or outer wall) and the color to be simulated. In the upper part of the frame of the layer / color selection tool 40, a “+” mark, a “part”, a “color name”, and an “x” mark are arranged side by side. When selecting a part, if a “+” mark is touched, a part selection screen (not shown) is displayed on the display, so the part is selected on the screen. Next, since a screen (not shown) for selecting a color name is displayed, the color name is selected in the screen. When the part and color name are selected in this way, the selected part and color name are displayed in the lower part of the frame of the layer / color selection tool 40. Further, by touching the “x” mark, the data of the selected part and color name can be deleted.

  In the case of performing simulation, after selecting a part and a color name by the layer / color selection tool 40, the above-described painting tool 30 changes the color of the selection range.

  FIG. 4 shows a control flow of a program stored in the tablet terminal for changing the color of the part selected in the building. First, in steps S <b> 1 to S <b> 3, an area for color change is selected by the automatic selection tool of the painting tool 30. That is, in step S1, the tapped position on the screen and the surrounding area are automatically selected. Specifically, a range up to the designated approximate color is automatically selected based on the three primary color (RGB) values of the light of the pixel at the tapped position to obtain a mask image. In step S2, the above approximate color is designated based on the operation of the “automatic selection area” of the painting tool 30. In step S3, it is determined whether or not an additional operation for increasing the selected area has been performed. When the tap operation is performed again and the additional operation is performed, the determination of “no additional range” in step S3 is denied and the area of the mask image is increased. Thereafter, in step S2, the range is changed based on the operation of the “automatic selection area” of the painting tool 30. Of course, the selection of the color change area may be performed using other means described in the painting tool 30 in addition to such automatic selection.

  If the additional tap operation is not performed and the determination in step S3 is affirmative, the mask image of the area selected by the above-described automatic selection tool and the color selected by the layer / color selection tool 40 are determined in step S4. The RGB display data is converted into color space display data including three elements of hue, saturation, and lightness (HSV). In step S5, the base color of the mask image is calculated. Specifically, as shown in FIG. 5, the maximum value (“131” in FIG. 5) in the brightness histogram of the mask image displayed in the HSV color space is obtained as the base color. As the base color obtained at this time, the color of the area first selected in steps S1 to S3 is used, and the color of the area additionally selected is not used. This prevents the base color from changing each time an area is added.

  In step S 6, the color of the mask image is converted to the color selected by the layer / color selection tool 40. Specifically, the HSV data of the mask image in the area selected by the automatic selection tool is replaced with the HSV data of the color selected by the layer / color selection tool 40. At this time, only the brightness data in the HSV data is not replaced, and the brightness data obtained in step S5 is left as it is. FIG. 6 schematically shows this state. That is, when the color of the mask image is converted to the selected color, the RGB data changes as shown in FIG. 6A, and the data represented by the HSV value also changes in the same manner. However, in the conversion in step S6, the hue (H) and saturation (S) data change as shown in FIG. 6B, but the lightness (V) data is fixed and not changed. By not changing the brightness data in this way, when the color of the mask image is converted to the color selected by the layer / color selection tool 40, the color of the selected area of the building is changed to the selected color. However, the darkness and darkness due to the influence of the shade in the building that is a three-dimensional object is reflected as it is.

  In step S7, it is determined whether or not the color data converted in step S6 has color saturation. Specifically, it is determined whether or not the lightness data of the color obtained by the conversion in step S6, that is, the dynamic range of the lightness data of the base color is within the range of 0 to 255. If it is within the range, a negative determination is made in step S7 because there is no color saturation, but if it is not within the range, a positive determination is made that there is color saturation and step S7 is affirmed and the dynamic range is compressed in step S8. Done. For example, the dynamic range is compressed by performing a process of compressing the entire dynamic range so that only the dynamic range falls within the range of 0 to 255 without changing the histogram pattern shown in FIG. If a negative determination is made in step S7, the process in step S8 is skipped. By thus compressing the dynamic range so as not to cause color saturation, whiteout or blackout on the display screen can be prevented.

  In step S9, since the color data converted in step S6 is a color space display composed of three elements of hue, saturation, and brightness (HSV), it is converted into RGB display data. By converting to RGB display data, the color of the selected area of the display screen 10 can be converted into the color selected by the layer / color selection tool 40 and displayed.

  In the above description, a case where a solid color is used as a color has been described. However, FIG. 7 illustrates a case where a variety of colors are used. Steps S1 to S3 in FIG. 7 are exactly the same as steps S1 to S3 in FIG. 4. Here, an area to be changed in color is selected by the automatic selection tool of the painting tool 30. In step S10, the color of the mask image is exchanged with a multicolored pattern selected by the layer / color selection tool 40. Further, in step S11, the RGB display data of the various colors selected by the mask image and the layer / color selection tool 40 is converted into color space display data composed of three elements of hue, saturation, and brightness (HSV). Is done.

  In step S12, the brightness data in the HSV color space display of the multicolor pattern and the mask image converted in step S11 are mixed at a predetermined ratio (for example, mask image: multicolor pattern = 2: 8). In the next step S13, the lightness data mixed in step S11 is compressed so as to correct the dynamic range that has expanded with the mixing. That is, processing of Ivoutput = Ivmix * Dnp / Dnmix is performed. Note that Ivoutput is the compressed brightness data, Ivmix is the mixed brightness data, Dnp is the dynamic range of the brightness data of the multicolor pattern, and Dnmix is the dynamic range of the mixed brightness data. Next, in step S14, the lightness data of the HSV color space display data of the multicolor pattern obtained in step S11 is replaced with the lightness data obtained in step S13. Further, the color space display data obtained as a result is converted into RGB display data and displayed in a selected area of the display screen 10. When the color of the mask image is converted into the multicolor pattern selected by the layer / color selection tool 40 by the processing of step S12 to step S14, the color of the selected area of the building is the selected multicolor. Although it is changed to a pattern, the light and darkness due to the influence of the shade in the building which is a three-dimensional object reflects the one when it was photographed. In addition, since the dynamic range is compressed by the processing in step S13, whiteout and blackout of the screen due to color saturation are prevented.

  As described above, according to the embodiment, when changing the color scheme of the selection area in the color image displayed on the display, the hue or saturation of the color or the pattern selected as the changed color or the changed pattern is changed. However, the lightness reflects the lightness of the color image initially displayed on the display. Therefore, it is possible to perform color arrangement on the display reflecting the shadow of the color image captured in accordance with the real thing, bringing the image of the three-dimensional object displayed on the display as close as possible to the actual one, A highly accurate simulation can be performed.
