FIG. 13 is an image diagram of an example of a main screen displayed on the monitor and an operation screen displayed on the operation panel. Screen images 100 to 111 in FIG. 13 are those of the main screen displayed on the monitor 7. Screen images 200 to 210 are those of an operation screen displayed on the operation panel 4.

  The control unit 8 continuously receives moving images taken by the camera 2. At this time, the control unit 8 displays the screen image 100 on the monitor 7 and displays the screen image 200 on the operation panel 4. Screen images 100 and 200 represent examples in which a screen saver is displayed.

  In step S1, the control unit 8 continuously determines whether or not the received moving image includes the user's face. The control unit 8 repeats the process of step S1 until it recognizes that the user's face is included in the moving image (NO in S1).

  If it is recognized that the user's face is included in the moving image (YES in S1), the control unit 8 proceeds to step S2 and activates software including a makeup simulation program for performing makeup simulation. At this time, the control unit 8 displays the screen image 101 on the monitor 7 and displays the screen image 201 on the operation panel 4.

Screen images 203 to 206 represent examples in which the contents (for example, names) of the makeup patterns of the screen images 103 to 106 displayed on the monitor 7 at that time are displayed. The control unit 8 sequentially displays the screen images 103 to 106 on the monitor 7 and displays the screen images 203 to 206 on the operation panel 4 until a predetermined time elapses or the user touches the operation panel 4.

  When the predetermined time has elapsed or the user touches the operation panel 4, the control unit 8 proceeds to step S 5, displays the screen image 107 on the monitor 7, and displays the screen image 207 on the operation panel 4. The screen image 107 represents an example in which a moving image obtained by photographing the user's face with the camera 2 is displayed, like the screen image 101. A screen image 207 represents an example in which an image selection screen capable of selecting one image from four makeup patterns (images) is displayed. The user can select one image from the image selection screen by operating the operation panel 4.

  In step S6, the control unit 8 repeats the process of step S6 until one image is selected from the image selection screen (NO in S6). When the user selects one image from the image selection screen, the operation panel 4 receives an operation from the user and outputs operation information to the control unit 8.

  If it is determined that the user has selected one image from the image selection screen (YES in S6), control unit 8 proceeds to step S7, and displays the image screen of the selected image on monitor 7 and operation panel 4. At this time, the control unit 8 displays the screen image 108 on the monitor 7 and displays the screen image 208 on the operation panel 4.

When receiving a printout instruction from the user, the control unit 8 displays the screen image 109 on the monitor 7 and displays the screen image 209 on the operation panel 4. A screen image 109 represents an example in which an image to be printed out is displayed. A screen image 209 represents an example in which a comment being printed out is displayed. The control unit 8 controls the printer 5 to print out the image displayed on the monitor 7.

  The user can also instruct display and printout of a comparison screen composed of image images before and after make-up by operating the operation panel 4. When receiving the display instruction of the comparison screen from the user, the control unit 8 displays the screen image 110 on the monitor 7. A screen image 110 represents an example in which a comparison screen including image images before and after makeup is displayed. When receiving a printout instruction from the user while the comparison screen is displayed, the control unit 8 controls the printer 5 to print out the comparison screen displayed on the monitor 7.

  When the makeup simulation by the user is finished, the control unit 8 displays screen images 111 and 210 as screen savers on the monitor 7 and the operation panel 4 and finishes the process.

  In the example of FIGS. 12 and 13, four images are displayed by the makeup simulation, but other images may be displayed. Further, the makeup simulation apparatus 1 shows an example in which makeup is applied to the user's face included in the moving image output from the camera 2, but the moving image captured in advance is stored as a moving image file in the auxiliary storage device 13 or the like. In addition, makeup may be applied to the user's face included in the moving image file.

  The makeup simulation apparatus 1 can also use the moving image output from the camera 2 other than the makeup simulation. FIG. 14 is an image diagram showing processing other than makeup simulation performed by the makeup simulation apparatus.

  A screen image 300 represents an example in which a moving image of a user's face photographed by the camera 2 is displayed. The makeup simulation apparatus 1 recognizes the user's face included in the moving image and cuts out a still image 301 of the user's face.

  The makeup simulation apparatus 1 can perform a face diagnosis and a skin color diagnosis of the still image 301 using the face analysis logic and the skin analysis logic, and display a screen image 302 representing the result on the monitor 7. Note that the processing for performing the face diagnosis and the skin color diagnosis of the still image 301 using the face analysis logic and the skin analysis logic is a known technique described in, for example, Japanese Patent Application Laid-Open No. 2001-346627.

  The makeup simulation apparatus 1 can also display a course selection screen 303 such as a screen image 303 on the monitor 7 to allow the user to select each course (for example, trend, basic, and free). The makeup simulation apparatus 1 displays screen images 304 to 309 based on the course selected by the user on the monitor 7 to perform simulation and advice.

  Screen images 304 to 306 represent examples in which a simulation screen of each course is displayed. Screen images 307 to 309 represent examples in which an advice screen for each course is displayed.

  For example, the basic course is a simulation and advice of an optimal makeup technique based on the results of the face diagnosis and the skin color diagnosis. The trend course is a simulation and advice on the latest trend makeup. The free make-up course is a simulation and advice for items corresponding to the eyes, mouth, cheeks, eyebrows, and individual parts.

It is a configuration.

  The analog camera 21 outputs, for example, a captured NTSC moving image via the USB capture device 22. The moving image output from the USB capture device 22 is input to the simulator main application 28 using, for example, DirectX 31 as an example of an API (Application Programming Interface). The moving image file 23 is also input to the simulator main application 28 using DirectX 31.

  The makeup camera 24 outputs the captured moving image via IEEE1394 as an example of a serial interface. The moving image output from the makeup camera 24 is input to the simulator main application 28 using the dedicated API 32. The simulator main application 28 obtains a moving image resolution original image and a still image resolution still image from a moving image input using the dedicated API 32.

  The simulator main application 28 uses a moving image and moving image file 23 input using DirectX 31 and a moving image with a moving image resolution obtained from a moving image input using the dedicated API 32 as an original image. Trim and reduce the image.

  The simulator main application 28 trims the original image to obtain a pre-makeup image. Further, the simulator main application 28 performs a reduction process on the original image to obtain a face recognition processing image. The face recognition processing unit 33 obtains a tracking point 34 to be described later for recognizing the user's face from the face recognition processing image by FFT (Fast Fourier Transform).

  Based on the tracking point 34, the makeup processing unit 35 performs makeup including foundation, eyebrows, shadow, lipstick, and teak on the user's face included in the pre-makeup image to obtain a post-makeup image. The makeup processing unit 35 includes a foundation processing unit 36, an eyebrow processing unit 37, a shadow processing unit 38, a lipstick processing unit 39, and a cheek processing unit 40.

  It should be noted that the makeup processing unit 35 can include product information 41 for makeup as in the post-makeup image in the post-makeup image. The moving image server 42 can write the pre-makeup image and the post-makeup image in the shared memory 27 and output the pre-makeup image and the post-makeup image as the moving image file 26.

  The interface application 29 includes a moving image control object 52, a moving image display object 53, and other controllers 54 that use the ActiveX controller 50 and the ActiveX viewer 51. Note that the interface application 29 and the simulator main application 28 are linked by ActiveX & Socket.

  The interface application 29 can display the pre-makeup image and the post-makeup image written in the supply memory 27 on the monitor 7 using the ActiveX viewer 51.

  The simulator main application 28 performs trimming and reduction processing on a still image having a still image resolution obtained from a moving image input using the dedicated API 32. The simulator main application 28 trims a still image having a still image resolution. Further, the simulator main application 28 performs a reduction process on the still image having the still image resolution to obtain a face recognition processing image. The face recognition processing unit 43 obtains a tracking point 44 described later for recognizing the user's face from the face recognition processing image.

  Based on the tracking point 44, the simulator main application 28 extracts a detailed part from the user's face included in the trimmed moving image, and obtains additional information such as the type and skin color used for the face diagnosis and the skin color diagnosis from the detailed part. Then, the tracking point 45 with additional information added to the tracking point 44 and the still image with the still image resolution obtained from the moving image input using the dedicated API 32 are output to the still image system 25.

  The still image system 25 can use the tracking point 45 to perform the face diagnosis and the skin color diagnosis of the still image 301 by using the face analysis logic and the skin analysis logic described above, and display a screen image 302 representing the result on the monitor 7. In addition, the still image system 25 can also display the screen images 303 to 309 on the monitor 7.

  Proceeding to the contour extraction image creation process in step S 12, the lipstick processing unit 39 creates a contour extraction image from the partial image 501. Proceeding to the contour extraction process in step S 13, the lipstick processing unit 39 extracts the lip contour from the contour extraction image using points as shown in the partial image 502.

  FIG. 22 is an image diagram showing an example of the contour extraction process. The contour extraction image 600 displays eight lips and three nose tracking points superimposed. The lipstick processing unit 39 re-searches based on the tracking points of 8 lips and 3 noses to extract the points of the contour extraction image 601.

  FIG. 23 compares the tracking points of the lips 8 points and 3 noses of the contour extracting image 600 with the points of the contour extracting image 601 extracted by re-searching based on the tracking points of 8 lips and 3 noses. It is a screen. When the re-search is not successful, the default points as shown in FIG. 24 calculated from the tracking points of 8 lips and 3 noses of the contour extraction image 600 are employed.

  FIG. 24 is an image diagram showing an example of processing for obtaining a default point from tracking points of 8 lips and 3 noses. The lipstick processing unit 39 refers to the three tracking points of the nose and obtains default points for the five upper lips.

  Proceeding to the spline curve generation process in step S14, the lipstick processing unit 39 interpolates the points of the contour extraction image 601 or the default points as shown in FIG. 24 with a secondary spline to complete the contours as shown in FIG. FIG. 25 is an image diagram showing processing for completing a contour from a point or a default point. When the contour of the lips is completed as in the partial image 503, the lipstick processing unit 39 proceeds to step S15, and performs a rotation return process that restores the rotation performed in the cut-out and rotation process in step S11.

  Proceeding to the color painting map generation process of step S16, the lipstick processing unit 39 generates a color painting map that determines the strength of color painting from the brightness and saturation of the partial image 700. FIG. 26 is an image diagram illustrating an example of a color painting map generation process. Specifically, the lipstick processing unit 39 generates a gray scale image 701 representing the intensity of color coating from the brightness and saturation. The lipstick processing unit 39 cuts out only the partial image 702 surrounded by the outline of the lips completed by the spline curve generation processing in step S 14 from the gray scale image 701 as the color painting map 504.

  Proceeding to the color painting process based on the color painting map in step S21, the lipstick processing unit 39 is set in the color painting map 504 generated in the color painting map generation process in step S16 and the makeup process parameter file as shown in FIG. The pre-makeup image is colored based on the makeup method and the designated color.

  FIG. 27 is an image diagram illustrating an example of a color painting process based on the color painting map. The lipstick processing unit 39 is based on the makeup application method and designated color set in the makeup processing parameter file 801 as shown in FIG. 19 and the color painting map 802 generated by the color painting map generation processing in step S16. Then, the pre-makeup image 803 is colored to obtain a post-makeup image 804.

  Then, the process proceeds to the debug & design drawing process in step S22. After the lipstick processing unit 39 performs the debug & design drawing process, the lipstick process ends.

(Shadow processing)
As shown in FIG. 28, the shadow processing unit 38 included in the simulator main application 28 performs shadow processing by referring to the tracking points 34 of three eyes and one eyebrow separately for the left and right. FIG. 28 is an image diagram showing tracking points referred to by shadow processing.

  FIG. 29 is a flowchart illustrating an example of shadow processing. The shadow process is roughly divided into a preparatory process in step S30 and a color painting process in step S40. The pre-preparation process includes the basic contour generation process in step S31.

  The color painting process is repeated for the color painting pattern, based on the color painting outline generation process in step S41, the color painting center generation process in step S42, the color painting map generation process in step S43, and the color painting map in step S44. It consists of a color painting process and a debug & design drawing process in step S45.

  Proceeding to the basic contour generation processing in step S31, the shadow processing unit 38 obtains the shape of the eyes of the user's face from the face recognition processing image as in the partial image 900. FIG. 30 is an image diagram illustrating an example of basic contour generation processing.

  Since the shadow processing unit 38 generates a contour that is the basis of the color painting contour, as shown in the partial image 1001, the vertical direction is searched from the center of the eye, and the eye contour (upper boundary & lower boundary) is recognized at two points. To do. The shadow processing unit 38 adds four points generated by spline interpolation to the recognized two points of the outline of the eye, the corner of the eye, and the four points of the eye, and generates a polygon with a total of eight points as in the partial image 1002.

  Proceeding to the color painting contour generation process in step S41, the shadow processing unit 38 creates a color painting contour like the partial image 901. FIG. 31 is an image diagram illustrating an example of the color painting contour generation process. Since the shadow processing unit 38 generates a colored outline, as shown in the partial image 1101, it generates a colored outline based on the corners of the eyes and the eyes. It should be noted that parameters such as contour expansion and vertex shift may be designated by GUI.

  Proceeding to the color painting center generation process in step S 42, the shadow processing unit 38 generates the color painting center position as “●” in the partial image 902. Proceeding to the color painting map generation process of step S43, the shadow processing unit 38 generates a color painting map that determines the strength of color painting as in the partial image 903.

  Specifically, in the color painting map generation process, the strength of painting is determined in accordance with the distance from the color painting center to the side of the polygon. For example, the shadow processing unit 38 determines the color coating map so that the closer to the side, the weaker the coating strength. It should be noted that the color painting map generation process is targeted for a portion excluding the basic contour from the color painting contour.

  As shown in FIG. 32, the shadow processing unit 38 generates a smoother gradation by applying a blurring process to the generated color painting map. FIG. 32 is an image diagram of an example showing a color map that has not been subjected to the blurring process and a color map that has been subjected to the blur process.

  Proceeding to the color painting process based on the color painting map in step S44, the shadow processing unit 38 is set in the color painting map 903 generated in the color painting map generation process in step S43 and the makeup processing parameter file as shown in FIG. The pre-makeup image is colored based on the makeup application and the designated color, and an after-makeup image is obtained.

  Then, the process proceeds to the debug & design drawing process in step S45, and after performing the debug & design drawing process, the shadow processing unit 38 ends the shadow process. Note that the shadow processing unit 38 can also realize multicolor coating by repeatedly performing the processing of steps S41 to S45 for the color coating pattern.

(Cheek treatment)
As shown in FIG. 33, the cheek processing unit 40 included in the simulator main application 28 performs cheek processing with reference to the tracking points 34 of the corners of the eyes and the corners of the mouth (separate left and right) and the center of the eyes and the nose (for stabilization). FIG. 33 is an image diagram showing tracking points referred to by the cheek processing.

  FIG. 34 is a flowchart illustrating an example of cheek processing. The cheek process is composed of a color painting outline generation process in step S50, a color painting process in step S51, and a debug & design drawing process in step S52.

  Proceeding to the color painting contour generation processing in step S50, the cheek processing unit 40 creates a contour polygon as a color painting contour based on the corners of the eyes and the mouth corners in order to generate a color painting contour. FIG. 35 is an image diagram showing an example of a color outline. Note that the number, size, shape, position, etc. of the contour polygon may be designated by a GUI.

  Proceeding to the color painting process in step S51, the cheek processing unit 40 determines the strength of the paint corresponding to the distance from the color painting center to the side of the contour polygon. Note that if the processing cost is too high for determining the coating strength, the coating strength may be determined by reducing the resolution (parameter specification using the GUI) (thinning in a mosaic pattern). The cheek processing unit 40 performs coloring on the pre-makeup image based on the determined coating strength, the makeup method and the designated color set in the makeup processing parameter file as shown in FIG. Get an image after up.

  Then, the process proceeds to the debug & design drawing process in step S52, and the cheek processing unit 40 ends the cheek process after performing the debug & design drawing process.

(Eyebrow processing)
As shown in FIG. 36, the eyebrow processing unit 37 included in the simulator main application 28 refers to the right and left eye corners, the eye center, and the two eyebrow tracking points 34 to perform eyebrow processing. FIG. 36 is an image diagram showing tracking points referred to by eyebrow processing.

  FIG. 37 is a flowchart illustrating an example of eyebrow processing. The eyebrow process is roughly divided into an eyebrow outline extraction process in step S60, an original eyebrow area erasing process in step S70, an eyebrow shape deforming process in step S80, and a deformed eyebrow pasting process in step S90.

  The original eyebrow area erasing process includes the area expanding process in step S71 and the eyebrow erasing process in step S72. The eyebrow shape deformation process includes an instruction curve creation process corresponding to the deformation designation in step S81 and a deformed eyebrow generation process in step S82.

  Proceeding to the eyebrow contour extraction process in step S60, the eyebrow processing unit 37 obtains the shape of the eyebrow of the user's face from the face recognition processing image as a partial image 2001. FIG. 38 is an image diagram illustrating an example of an eyebrow contour extraction process. In order to extract the outline of the eyebrows, the eyebrow processing unit 37 searches the eyebrows to the left and right around the buttocks (actually near the center of the eyebrows) as shown in the partial image 2101. As shown in the partial image 2102, the eyebrow processing unit 37 recognizes the outline shape of the eyebrows from the search result.

  Proceeding to the expansion processing of the region in step S71, the eyebrow processing unit 37 expands the region representing the recognized outline shape of the eyebrow. Proceeding to the eyebrow erasing process in step S72, the eyebrow processing unit 37 erases the eyebrows by painting the expanded region using the skin color in the vicinity. In addition, the eyebrow processing unit 37 performs a process of blending in the boundary portion of the expanded region.

  Proceeding to the instruction curve creation process corresponding to the deformation designation in step S81, the eyebrow processing unit 37 deforms the recognized area (skeleton) representing the outline shape of the eyebrow according to the designation. FIG. 39 is an image diagram showing an example of a process for creating an instruction curve corresponding to the deformation designation.

  As shown in the partial image 2201, the eyebrow processing unit 37 replaces the region representing the recognized outline shape of the eyebrow with a skeleton 2202 composed of a horizontal axis and a plurality of vertical tangs, and the shape of the axis and the height of the tangs. For example, the transformation process can be performed like a skeleton 2203.

  Proceeding to the deformed eyebrow generation process in step S 82, the eyebrow processor 37 generates a deformed eyebrow from the skeleton 2203. Proceeding to the process of attaching the deformed eyebrows in step S90, the eyebrow processing unit 37 attaches the deformed eyebrows to the pre-makeup image to obtain an image after make-up.

(Foundation treatment)
As shown in FIG. 40, the foundation processing unit 36 included in the simulator main application 28 refers to the right and left eye corners, the eyes and one eyebrow, and the tracking points 34 between the eyes and the center of the nose to perform the foundation processing. FIG. 40 is an image diagram showing tracking points referred to by the foundation process.

  FIG. 41 is a flowchart illustrating an example of the foundation process. The foundation process includes a contour generation process in step S101, a blurring process on the target image in step S102, and an image pasting process in step S103. Note that the processing of steps S101 to S103 is repeated for the target area.

  Proceeding to the contour generation processing in step S101, the foundation processing unit 36 generates three types (four locations) of the forehead, nose, and cheek (left and right) as shown in the image of FIG. FIG. 42 is an example of an image representing an outline. It should be noted that the size, position, etc. of each contour may be designated by a GUI.

  Proceeding to the blurring process on the target image in step S102, the foundation processing unit 36 performs the blurring process on the target image corresponding to the generated contour as shown in FIG. FIG. 43 is an image diagram illustrating an example of an original image before blurring processing and an original image after blurring processing. By the blurring process on the target image, the foundation processing unit 36 can smooth the fine roughness of the skin.

  Proceeding to the image pasting process in step S103, the foundation processing unit 36 pastes the target image after the blurring process on the three types (four locations) of the forehead image, nose, and cheek (left and right) of the pre-makeup image, Get an image after makeup.

  In Example 2, other examples of lipstick processing, shadow processing, cheek processing, eyebrow processing, and foundation processing will be described.

(Lipstick treatment)
The lipstick processing unit 39 included in the simulator main application 28 refers to the tracking point 34 as follows and performs lipstick processing.

  44 and 45 are flowcharts of an embodiment of lipstick processing (lip pen drawing processing). In FIG. 45, first, in step S301, a face image of a rectangular region surrounding the mouth is acquired, and mouth outline data is acquired. The mouth contour data is obtained by the tracking point (feature point) 34.

  In the next step S302, a curve drawing section and a line drawing section are set according to the makeup pattern selected by the user. FIG. 46 is an image diagram of an example of a face image of a rectangular area surrounding the mouth.

  In this figure, the upper ends M2 and M4 of the mouth (upper lip), the left and right ends M1 and M5 of the mouth, the lower end M6 of the mouth (lower lip), the characteristic points (tracking points), and the lower part of the mouth (lower lip) A point M7 that is 1/3 of the mouth width (distance between M1 and M5) from the left end M1 at the edge, and 1 / of the mouth width (distance between M1 and M5) from the right end M5 at the lower edge of the mouth (lower lip). A point M8 at a distance of 3 is shown.

  When the selected makeup pattern is fresh, the lipstick processing unit 39 draws sections M1 to M2 and sections M4 to M5 as curves, and draws sections M2 to M3 and sections M3 to M4 as straight lines. Thus, as shown in the drawing image of FIG. 47A, the lip pen drawing for rounding the upper lip is performed, and the lip pen drawing is not performed for the lower lip.

  When the selected makeup pattern is sweet, the lipstick processing unit 39 draws each of the sections M1 to M2, the sections M4 to M5, and the sections M1 to M6 to M5 as curves, and each of the sections M2 to M3 and sections M3 to M4. Is drawn with a straight line. As a result, as shown in the drawing image of FIG. 47B, lip pen drawing is performed to round the upper and lower lips.

  When the selected makeup pattern is cute, the lipstick processing unit 39 draws each of the sections M1 to M7, the sections M7 to M8, and the sections M8 to M5 with straight lines. Thus, as shown in the drawing image of FIG. 47C, the lip pen drawing for making the lower lip straight is performed, and the lip pen drawing is not performed for the upper lip.

  When the selected makeup pattern is cool, the lipstick processing unit 39 draws the sections M2 to M4 as curves, and sections M1 to M2, sections M4 to M5, sections M1 to M7, sections M7 to M8, sections M8 to M5. Each is drawn with a straight line. Thus, as shown in the drawing image of FIG. 47D, lip pen drawing is performed to make the upper lip and lower lip straight.

  In the next loop processing in step S303, the lipstick processing unit 39 sequentially increases the x-coordinate value from 0 (the left end M1 position of the mouth) to the maximum value (the right end M5 position of the mouth) in pixel units. Note that the x coordinate increases to the right in the rectangular region surrounding the mouth shown in FIG. 46, and the y coordinate increases to the upper side. In step S304 in this loop, the lipstick processing unit 39 determines whether or not it is a curve drawing section. If it is not a curve drawing section, the process returns to step S303 to increase the x coordinate value.

  If it is a curve drawing section, the process proceeds to step S305, and the lipstick processing unit 39 refers to the offset curve shown in FIG. 48 with the x-coordinate value to obtain an offset value for the x-coordinate. The offset shown in FIG. 48 is used to lift the upper edge of the upper lip upward (toward the nose) to make the mouth look larger, and the lower edge of the lower lip has an offset value = 0.

  Next, the lipstick processing unit 39 performs a loop process in step S306. Here, the lipstick processing unit 39 sequentially increases the y coordinate value in units of pixels from the y coordinate + offset value−β of the mouth contour data to the y coordinate + offset value + β of the mouth contour data, Process. This β is ½ of the pen width of the lip pen (for example, equivalent to several mm).

  In step S307 in the loop of step S306, the lipstick processing unit 39 calculates the saturation (S), hue (H), and brightness (V) from the RGB values of the pixels corresponding to the xy coordinates using a predetermined arithmetic expression. calculate.

  In step S308, the lipstick processing unit 39 reduces the HSV value of the color of the lip pen in proportion to the difference based on the difference between the y coordinate of the mouth contour data and the y coordinate (maximum offset value + β). Then, after adding a gradient, the pixel is added to the HSV value of the pixel corresponding to the xy coordinate obtained in step S307.

  Thereafter, the lipstick processing unit 39 converts the HSV value of the pixel corresponding to the xy coordinate into an RGB value in step S309, and overwrites and updates the pixel corresponding to the xy coordinate using the RGB value in step S310. By doing so, the lip pen is drawn.

  This step S306 is executed only once because the curve drawing section is only the upper edge of the upper lip in the drawing image of FIG. 47A, but the curve drawing section is above the upper lip in the drawing image of FIG. 47B. It is executed twice because there is an edge and a lower edge of the lower lip. When drawing the lower edge of the lower lip, the offset value in FIG. 48 is handled as a negative value. When the loop process of step S303 is completed, the lipstick processing unit 39 proceeds to step S311 and obtains a straight line function of each straight line drawing section. In the next loop processing in step S312, the lipstick processing unit 39 sequentially increases the x-coordinate value from 0 (the left end M1 position of the mouth) to the maximum value (the right end M5 position of the mouth) in units of pixels.

  In step S313 in this loop, the lipstick processing unit 39 determines whether or not it is a straight line drawing section. If it is not a straight line drawing section, the process returns to step S312 to increase the x coordinate value. If it is a straight line drawing section, the process proceeds to step S314, and the lipstick processing unit 39 obtains the y coordinate Y (L) of the straight line corresponding to the x coordinate using a straight line function.

  Next, the lipstick processing unit 39 performs a loop process in step S315. Here, the lipstick processing unit 39 sequentially increases the y coordinate value from Y (L) −β to Y (L) + β in units of pixels, and performs the following processing. This β is ½ of the pen width of the lip pen (for example, corresponding to several mm).

  In step S316 in the loop of step S315, the lipstick processing unit 39 calculates the saturation (S), hue (H), and brightness (V) from the RGB values of the pixels corresponding to the xy coordinates using a predetermined arithmetic expression. calculate. In step S317, the lipstick processing unit 39 corrects the HSV value of the color of the lip pen so as to become lighter in proportion to the difference based on the difference between Y (L) and the y coordinate (β at the maximum). After adding gradation, the value is added to the HSV value of the pixel corresponding to the xy coordinate obtained in step S316.

  Thereafter, the lipstick processing unit 39 converts the HSV value of the pixel corresponding to the xy coordinate into an RGB value in step S318, and overwrites the pixel corresponding to the xy coordinate using the RGB value in step S319 to update. By doing so, the lip pen is drawn.

  The step S315 is executed only once in the drawing image of FIG. 47C because the curve drawing section is only the upper edge of the upper lip, but in the drawing image of FIG. 47D, the curve drawing section is on the upper lip. It is executed twice because there is an edge and a lower edge of the lower lip. When the loop process of step S312 ends, the lipstick processing unit 39 ends the lipstick process.

  As described above, when a desired type is selected from a plurality of makeup patterns, the lipstick processing unit 39 sets a shape to be drawn (color painting processing) with the lip pen in accordance with the selected makeup pattern. Since the drawing is performed with the lip pen in the shape, the vicinity of the contour of the mouth can be drawn and displayed with the lip pen according to the selected makeup pattern simply by selecting the desired type.

  Also, since the lipstick processing unit 39 adds a gradation that makes the color of the lip pen lighter as the vertical distance from the outline of the mouth increases, the color of the lip pen that does not feel strange because the color of the drawn lip pen becomes similar to the skin color of the face image. Can be displayed.

  The lipstick processing unit 39 included in the simulator main application 28 may calculate the following points from the tracking point 34 and perform the lipstick processing of the first or second embodiment with reference to the points.

  The positions of a plurality of points set in advance for grasping the morphological characteristics of the lips can be calculated from the tracking points 34. FIG. 49 is an image diagram showing an example of positions of a plurality of points set in advance for grasping the morphological characteristics of the lips. FIG. 49 shows the following 14 points.

  The 14 points shown in FIG. 49 are the positions of both sides of the nose (2 points), the center of the nostril (2 points), the position of the upper lip crest (2 points), the position of the valley of the upper lip, the center position of the lips, 14 points of position (2 points), lower lip center position of lower lip, center position of chin, and both side positions of chin (2 points). Note that the position and number of the points are not particularly limited, and the position and number can be changed as long as the morphological characteristics of the lips can be grasped and it is suitable for creating makeup information. I can do it.

  The lipstick processing unit 39 determines the planar characteristics analyzed based on the 14-point position for the following five items, and grasps the balance of the entire lip of the subject. The lipstick processing unit 39 measures the difference of the grasped balance of the entire lip of the subject against the optimum balance as a reference, and corrects the portion different from the reference. It should be noted that the lip balance as a reference depends on the lip proportion that is evaluated as beautiful.

  The five items for determining the balance of the lip shape are the position of the mouth corner, the position of the upper lip, the position of the lower lip, the position of the upper lip crest, and the angle between the upper lip crest and trough. The standard of 5 items in the optimal balance is the position of the corner of the mouth with the inside of the black eye down, the position of the upper lip is 1/3 of the distance from the bottom of the nose to the center of the lip, the position of the lower lip is 1/3 of the distance from the center position of the chin to the center position of the lips, the position of the mountain of the upper lip is the position where the center of the nostril is lowered, and the angle between the mountain and valley of the upper lip is lowered by 10 degrees from the mountain to the valley Based on angle.

  In accordance with the optimal lip reference balance, the lipstick processing unit 39 compares the balance of the makeup target lips to grasp the difference between them, and corrects the target lip to the reference balance. Here, the correction method will be described. First, the lipstick processing unit 39 draws a horizontal line from the center of the lips, and measures whether the position of the mouth corner is above or below the horizontal line. When the position of the lip is above the horizontal line, the lipstick processing unit 39 does not particularly make correction. When it is below, the lips are not tightened and appear sloppy, so the lipstick processing unit 39 applies correction makeup so as to correct the position of the mouth corner upwards with a limit of 2 mm.

  The reason for setting the adjustment limit to 2 mm is to avoid unnatural adjustment results. For example, when a beauty consultant advises a customer about the makeup of lips at a store, etc., and proposes a makeup method that approximates the standard lips, it is usually changed within a range of about 2 mm. Thus, if the correction range exceeds 2 mm, the width of the correction becomes too large and the makeup becomes unnatural. If the initial mouth corner point position is shifted, the optimum balance point is also shifted, so the mouth corner point is adjusted manually. This correction range of 2 mm is the same for other parts.

  Next, the lipstick processing unit 39 corrects the shapes of the peaks and valleys of the upper lip. The lipstick processing unit 39 sets the position by determining the position of the upper lip crest on the basis of the position of 1/3 of the distance from the bottom of the nose to the center of the lip and the position from the center of the nostril. The makeup point is set on the screen so that the peak of the upper lip comes to the specified position.

  Next, the lipstick processing unit 39 sets an angle at which the position of the valley of the upper lip is lowered by 10 degrees from the mountain toward the valley based on the reference. This angle is in the range of 10 to 15 degrees, for example, but is set in advance to 10 degrees, for example. However, this angle is not limited to 10 degrees, and can be arbitrarily set in the range of 10 to 15 degrees.

  Next, the lipstick processing unit 39 sets the position of the lower lip at a position 1/3 of the distance from the center line of the lips to the center position of the chin, and further sets the lower chin line at the center position and three points on both sides thereof. The point positions are drawn with arcs, and the lower lip line is drawn in a shape similar to the arc shape of the lower jaw. The lower jaw line can be automatically drawn by deforming the basic form following the lower jaw line on the computer screen.

  In this way, the lipstick processing unit 39 grasps the difference of the overall balance of the subject's lips against the optimal balance based on the criteria of the five items, and sets a line for correcting to the optimal balance. Can be sought.

(Shadow processing)
The shadow processing unit 38 included in the simulator main application 28 refers to the tracking point 34 as follows and performs shadow processing. Note that the shadow processing is executed in the order of eyeline search processing, eyeline drawing processing, and eyeshadow application processing.

  FIG. 50 is a flowchart of an example of eyeline search processing. In the figure, first, a face image of a rectangular area surrounding the eyes and eyebrows is acquired in step S401, and an area for holding a binary image is secured in the memory device 11 or the like in step S402. In the next loop processing in step S403, the threshold value TH is sequentially increased from the minimum value to the maximum value in increments of a predetermined value, and in step S404 in the loop, the threshold value TH is used to binarize the face image of the rectangular area surrounding the eyes and eyebrows. To do. The reason why binarization is performed by changing the threshold value TH is to accurately detect the eyeline.

  In the next step S405, median filter processing is performed on the edge image obtained by binarization to remove noise. This is done to remove noise generated by eyelashes and the like. In step S406, it is determined whether or not there is a plurality of edge pixels that extend continuously in the eye width direction (y direction in the rectangular area), that is, contour line forming pixels, in the edge image. If there is no contour line forming pixel, the threshold value TH is increased by an increment of a predetermined value, and the process returns to step S404. If there is the contour line forming pixel, the process proceeds to step S407.

  In step S407, a contour line is extracted from the binary image. Next, the shadow processing unit 38 performs linear interpolation (or curve interpolation) on the discontinuous portion of the contour line extracted in step S408, and further performs median filter processing on the contour line after interpolation in step S409 to remove noise. Then, this process ends.

  FIG. 51 is a flowchart of an embodiment of eyeline drawing processing. This process is performed for the upper eyelid region on the upper side (eyebrow side) from the contour line of the upper eyelid connecting the eyes EL4, ER4 and the eye corners EL1, ER1.

  In the figure, first, an eyeline drawing pattern is set in step S410. When cool is selected as the makeup pattern, the eyeline drawing pattern is an eyeline having a width from the top of the upper eyelid to the corner of the eye as shown in FIG. 52, and the x-direction corner of the eye in the hatched area Ia. An eyeline drawing pattern for blurring the eyeline is set on the side.

  Further, when fresh is selected as the makeup pattern, as shown in FIG. 53, the eyeline has a width from the center of the upper eyelid (intermediate point between the eyes and the corners of the eyes) to the corner of the eyes, and is hatched. In the area Ib, an eyeline drawing pattern for blurring the eyeline is set on the x direction corner of the eye.

  When sweet is selected as the makeup pattern, as shown in FIG. 54, an eyeline drawing pattern is set which is an eyeline with a width from the upper eyelid to the outer corner of the eyelid and does not blur the eyeline. Is done.

  Furthermore, when cute is selected as the makeup pattern, as shown in FIG. 55, the eyeline has a width from the top of the upper eyelid to the corner of the eyelid, and the eyed on the eyebrows side in the y direction in the hatched area Id. An eyeline drawing pattern for blurring lines is set.

  The eyeline drawing pattern corresponding to the above makeup pattern is a default value when the eyeline selection box is not touched, and a desired value is selected from the four eyeline drawing patterns displayed when the eyeline selection box is touched. It is also possible to select a pattern.

  Next, in the loop processing of step S411, the x coordinate value is sequentially increased from 0 (eye position) to the maximum value (eye corner position) in pixel units. In this loop, the loop process of step S412 is performed for each x coordinate value. Here, the y-coordinate value is sequentially increased from 0 (the y-coordinate of the contour line) to the maximum value (eye height width: maximum separation distance between the upper eyelid and the lower eyelid) in units of pixels, and the following processing is performed.

  In step S413, the brightness of the pixel indicated by the x coordinate and y coordinate is calculated. In step S414, it is determined whether the brightness of this pixel is the same as the brightness of the eyeline. If they are not the same, the y coordinate value is increased and the process returns to step S413.

  When the brightness of this pixel is the same as the brightness of the eyeline, the process proceeds to step S415, and the brightness of this pixel is lowered by a predetermined value from the current brightness. As a result, the brightness of the pixels on the contour line is lowered and darkened, and as a result, the eyeline can be conspicuous. Thereafter, in step S416, it is determined from the x coordinate and the y coordinate whether the region is Ia in FIG. 52 (in the case of sweet) or region Ib in FIG. 53 (in the case of cool), and the above regions Ia and Ib are determined. In this case, the eyeline is blurred in the x direction outer corner in step S417.

  Further, in step S418, it is determined from the x coordinate and y coordinate whether the region is Id in FIG. 55 (in the case of fresh), and in the case of the above region Id, the eyeline is blurred on the eyebrow side in the y direction in step S419. Do. Thereafter, when the loop processing in steps S411 and S412 is finished, the shadow processing unit 38 finishes the eyeline search processing.

  FIG. 56 is a flowchart of an embodiment of the eye shadow application process. In the figure, first, an eye shadow application region is set in step S430. Here, the maximum distance Ymax in the y direction from the contour line of the upper eyelid to the contour line of the eyebrows shown in FIG. 57 is obtained, and the maximum application size My = Ymax / α is obtained. Note that α = 2 when the makeup pattern is sweet or cute, α = 3 when it is cool, and α = 6 when it is fresh.

  Further, using the curves shown in FIGS. 58A and 58B, the upper limit (eyebrow side) of the eye shadow application region is obtained for each makeup pattern. At this time, the maximum application size My is used. Here, in the case of sweet, cool, or cute, the curve from the top of the eye to the corner of the eye shown in FIG. 58 (A) is used, and in the case of fresh, on the contour of the upper eyelid that is a predetermined length away from the top of the eye shown in FIG. A curve from one point to the corner of the eye is used. In addition, the lower limit of the eye shadow application area is the upper eyelid outline.

  In step S431, the movement locus of the start point is set, and in step S432, the application size at the start point of eye shadow application is set. FIG. 59 shows the eye shadow application region corresponding to FIG. 58 (A), and the approximate center position P0 of the lower limit (upper outline) of the eye shadow application region is set as the eye shadow application start point. Further, the radius of a circle that is centered on the start point and is in contact with the upper limit of the eye shadow application region is defined as the application size, and arrows A1 and A2 that are superimposed on the lower limit of the eye shadow application region are used as the movement locus of the start point.

  Next, in step S433, the eye shadow density at the start point is calculated from the user's skin color data and the selected eye shadow color using a predetermined arithmetic expression, and the obtained eye shadow color is applied to the start point. . In step S434, an airbrush process is performed in which the density of the color of the eye shadow applied to the start point is reduced (blurred) in proportion to the distance from the start point in a circle having the start point as the center and the application size as the radius. The color of the eye shadow at each pixel position obtained in this way is added to the skin color of the pixel at that position to obtain the color of each pixel with the eye shadow superimposed on the skin. Update the color.

  In the airbrush process described above, only a circle with the radius of the application size in the eye shadow application area is a target of processing, and the process is not performed in a semicircle portion below the lower limit of the eye shadow application area. In addition, the relationship between the distance from the center and the density in the airbrush process uses the characteristic that the density decreases in proportion to the distance from the center as shown in FIG. 60A when the makeup pattern is cute or fresh. In the case of sweet or cool, as shown in FIG. 60B, the characteristic that the degree of density decrease is large when the distance from the center is small, and the characteristic that the degree of density decrease is small when the distance from the center is large is used. .

  Thereafter, in step S435, the start point is moved by a predetermined distance according to the movement locus of the start point indicated by arrows A1 and A2. The start point is repeatedly moved from the position P0 in the arrow A1 direction by a predetermined distance. When the moved start point is outside the eye shadow application region, the start point returns to the position P0 and moves in the arrow A2 direction by the predetermined distance. To do. This moving distance is, for example, several tens of percent of the application size.

  Further, a new application size is calculated in step S436. The new application size decreases at a rate of several percent to several tens percent as the starting point moves from the position P0 in the directions of arrows A1 and A2.

  Next, in step S437, it is determined whether or not it is the end point of eye shadow application. If it is not the end point, the above steps S433 to S436 are repeated, and if it is the end point, the shadow processing unit 38 ends the eye shadow application process. The eye shadow application end point is determined when the start point moves in the direction of arrow A2 and is outside the eye shadow application region.

  As described above, when a desired type is selected from a plurality of makeup patterns, an area for applying eye shadow in the eye area of the face image is set according to the selected makeup pattern, and the face in the area for applying eye shadow is set. Since the eye shadow is applied to the image color by overlaying the eye shadow color, simply select the desired type and apply the eye shadow to the eye area of the face image according to the selected makeup pattern. it can.

  In addition, since the eye contour is detected and the detected eye contour and the vicinity thereof are drawn according to the selected makeup pattern, it is only necessary to select a desired type, and according to the selected makeup pattern. An eyeline can be drawn and displayed on the eye portion of the face image.

  In addition, since the eye shadow density is reduced and blurred as the distance from the application start point in the area where the eye shadow is applied is reduced, the applied eye shadow blends with the skin color of the face image and displays an eye shadow that does not feel strange. Since the start point of application is sequentially moved within the area where the eye shadow is applied, the applied eye shadow is compatible with the skin color of the face image regardless of the shape of the area where the eye shadow is applied. Eye shadow can be displayed.

  The shadow processing unit 38 included in the simulator main application 28 compares the eye form of the person to be makeup classified and grasped with the eye form of the standard balance in comparison with the eye form of the standard balance, You may make it the eye makeup which makes it look large and is well-balanced and attractive.

  The eye shape characteristics are classified by using four elements as indices: a frame axis indicating the shape of the eye fissure, a form axis indicating the uneven shape of the eye, an angle axis indicating the angle shape of the eye, and a standard balance eye shape. Can do. The frame form is an outline shape of an eyelid formed by upper and lower eyelids with the eyelash line as a guide. The frame axis is arranged on the axis according to the ratio of the upper and lower diameters and the left and right diameters. The frame axis is provided as a vertical axis, for example. The form of the standard balance eye described later is arranged at the center of the frame axis. On the one side of the frame axis, that is, on the upper side, an eye shape having a longer vertical diameter and a shorter left and right diameter is arranged than a standard balance eye in which the ratio of the vertical and horizontal diameters of the eye cleft is 1: 3. On the other side of the shaft, that is, the lower side, an eye shape having a short vertical diameter and a long horizontal diameter is arranged.

  Moreover, the form form which shows the uneven | corrugated shape of eyes is grasped | ascertained by the uneven | corrugated shape of the ridge of a ridge and the upper and lower eyelid, for example. The form axis is configured as a horizontal axis orthogonal to the frame axis. At the center of the form axis, a standard balance eye shape is arranged. On the left side of the form axis, that is, on the left side, the upper eyelid bulge is flatter than the standard balanced eye shape (single or deep double common bulge shape of the eyelid flesh) and the lower eyelid flesh Is thin and the curved surface of the eyeball is arranged in an inconspicuous eye form. On the other side of the shaft, that is, on the right side, the upper eyelid bulge is three-dimensional (a deeply carved state commonly seen in double and triple folds. In the lower eyelid, a prominent curved surface of the eyeball appears, or a form of the eye that is three-dimensional due to the bulge of orbital fat is placed.

  The angle form of the eyes is an angle formed by a horizontal line passing through the eyes and a diagonal connecting the eyes and the corners of the eyes. The standard balanced eye angle form is an angle greater than 9 degrees and less than 11 degrees, and most preferably an angle of 10 degrees. The shadow processing unit 38 determines that the angle is larger than 9 degrees and smaller than 11 degrees, is standard when the angle is larger than 9 degrees and smaller than 11 degrees, and lowers as the eye corner when the angle is 11 degrees or larger. To do. The angle axes indicating the top and bottom of the angle form of the eyes are expressed so as to exist individually in four quadrants divided by the two axes when the frame axis and the form axis are projected onto a plane.

  The features of the standard balance eye form are as follows: A frame shape in which the ratio of the upper and lower diameter of the eye fissure (perpendicular line passing through the center of the iris) and the left and right diameter is 1: 3; b. The shape of the upper and lower eyelids when the face is viewed from the side has no noticeable unevenness, and the curve from the eyebrow arch (slightly raised bone under the eyebrows) to the cheekbones is gentle Having a form, c. An angle formed by a horizontal line passing through the eyes and a straight line connecting the eyes and the corners of the eyes is 10 degrees, d. The ridge groove has an intermediate shape between double and deep double, the groove on the eye side is narrow, the groove on the outer corner side is wider than the eye side, e. The width of the upper and lower diameters of the eye fissure and the width from the upper edge of the eye fissure to the eyebrows have a balanced form of 1: 1. FIG. 61 is a front view showing the form of a standard balance eye.

(Cheek treatment)
The cheek processing unit 40 included in the simulator main application 28 refers to the tracking point 34 as follows and performs cheek processing.

  FIG. 62 is a flowchart of an example of a blusher application process (blush process). In the figure, first, a blusher application region and a start point are set in step S501, a movement locus of the start point is set in step S502, and an application size at the start point of blusher application is set in step S503. Steps S501 to S503 described above differ in processing depending on the makeup pattern selected by the user.

  When the makeup pattern is sweet, as shown in FIG. 63, the y-coordinates of the feature points of the corners EL1 and ER1 are y1 and the y-coordinates of the feature points of the left and right ends N1 and N3 are y2 in the face area. When the y-coordinates of the feature points of the left and right ends M1, M5 of the mouth are y3, the x-coordinates of the feature points of the eyes EL4, ER4 are x1, and the x-coordinates of the feature points of the corners EL1, ER1 are x3, Is in the range from (y1 + y2) / 2 to (y2 + y3) / 2 and the range where the x coordinate is between x1 and x3 is the blusher application region, and the position P0 at the approximate center of this region is the start point of blusher application And Moreover, 1/2 of the vertical width of this area is set as the application size, and arrows A1 and A2 are set as the movement locus of the starting point.

  When the makeup pattern is cool, as shown in FIG. 64, the y-coordinates of the feature points of the corners EL1, ER1 are y1 and the y-coordinates of the feature points of the left and right ends M1, M5 of the mouth are y3. X is the x coordinate of the feature points of the pupils PL and PR, x2 is the x coordinate of the feature points of the corners EL1 and ER1, and x of the feature points F6 and F7 on the face contour of the same y coordinate as the corners EL1 and ER1. When the coordinate is x4, the area surrounded by the straight line connecting the point (x2, y3) and the point (x4, y1), the line y = y3, and the face outline is defined as the blusher application area. The position P0 is used as the starting point for blusher application. Further, the radius of a circle inscribed in the blusher application area with the position P0 as the center is set as the application size, and arrows A1 and A2 are set as the movement locus of the start point.

  When the makeup pattern is cute, as shown in FIG. 65, the y-coordinates of the feature points of the corners EL1, ER1 are y1 and the y-coordinates of the feature points of the left and right ends N1, N3 of the nose are y2, as shown in FIG. The y-coordinates of the feature points of the left and right ends M1, M5 of the mouth are y3, the x-coordinates of the feature points of the pupils PL, PR are x2, the x-coordinates of the feature points of the corners EL1, ER1 are x2, and the corners EL1, ER1 The x-coordinates of the feature points F6, F7 on the face contour with the same y-coordinate are x4, and the x-coordinates of the feature points F10, F11 on the face contour with the same y-coordinates as the left and right ends M1, M5 of the mouth are x5. The range surrounded by the outline of the face and the straight line connecting the point (x2, y2) and the point (x4, y1), the straight line connecting the point (x2, y2) and the point (x5, y3) A region for application is set, and a position P0 in this region is set as a start point for blusher application. Further, the radius of a circle inscribed in the blusher application area with the position P0 as the center is set as the application size, and arrows A1 and A2 are set as the movement locus of the start point.

  When the makeup pattern is fresh, as shown in FIG. 66, the y-coordinates of the feature points of the corners EL1, ER1 are y1 and the y-coordinates of the feature points of the left and right ends M1, M5 of the mouth are y3. When the x coordinate of the feature point of the eye head EL4, ER4 is x1, the y coordinate is in the range from y3 to (y1 + y3) / 2, and the x coordinate is in the range from x1 to the face contour. The position P0 in this region is set as the start point of blusher application. Moreover, 1/2 of the vertical width of this area is set as the application size, and arrows A1 and A2 are set as the movement locus of the start point.

  Next, blusher is applied. Here, first, in step S504, the concentration of blusher at the start point is calculated from the user's skin color data and the selected blusher color using a predetermined calculation formula, and the obtained blusher color is applied to the start point. In step S505, an airbrush process is performed in which the density of the blusher color applied to the start point is reduced (blurred) in proportion to the distance from the start point in a circle centered on the start point and having a radius of application size. The color of the blusher at each pixel position obtained in this way is added to the skin color of the pixel at that position to obtain the color of each pixel overlaid with the blusher on the skin, and this updates the color of each pixel To do. FIG. 67 shows the relationship between the distance from the center and the density in the above airbrush process.

  Thereafter, in step S506, the start point is moved by a predetermined distance according to the movement locus of the start point indicated by arrows A1 and A2. The start point is repeatedly moved from the position P0 in the direction of the arrow A1 by a predetermined distance. When the moved start point is outside the blusher application region, the start point returns to the position P0 and moves in the direction of the arrow A2 by a predetermined distance. . This moving distance is, for example, several tens of percent of the application size. In step S507, a new application size is calculated. When the makeup pattern is sweet or fresh, the new application size is the same as the previous application, but when the makeup pattern is cool or cute, as the start point moves from the position P0 in the directions of arrows A1 and A2, The application size decreases at a rate of a few percent to a few tens of percent.

  Next, in step S508, it is determined whether or not the end point of the blusher application. If it is not the end point, the above steps S504 to S507 are repeated, and if it is the end point, the blusher application process is ended. The end point of blusher application is determined when the start point moves in the direction of arrow A2 and is outside the blusher application area.

  In this way, when a desired type is selected from a plurality of makeup patterns, an area for applying blusher in the face image is set according to the selected makeup pattern, and the color of the face image in the area for applying blusher is set, Since the blusher is applied by overlapping the colors of the blusher, the blusher can be applied and displayed on the cheek portion of the face image according to the selected makeup pattern simply by selecting the desired type.

  In addition, since the concentration of blusher is lowered and blurred as it is farther from the start point of application in the area where blusher is applied, the applied blusher is compatible with the skin color of the face image and can display blusher that does not feel strange, Since the start point of application is sequentially moved within the area where the blusher is applied, the applied blusher can be displayed with a blusher that is compatible with the skin color of the face image and does not feel uncomfortable regardless of the shape of the area where the blusher is applied.

  The shadow processing unit 38 included in the simulator main application 28 may perform cheek makeup according to the cheek morphological characteristics of the person to be makeup that is classified and grasped. In general, cheek makeup differs depending on the image to be produced. Therefore, in the present invention, examination was made focusing on “rendering of blood color”.

  The reason for paying attention to the blood color is based on the following three points. First of all, because blood color is an element that everyone originally has when it is in a healthy state, we thought it would lead to naturally bringing out the original healthy beauty of each individual. It is.

  In addition, as an example of cheeks with good blood color, for example, an infant's cheeks are self-explanatory, but in an example where `` the blood color is good and preferable '', the blood color is in the area connecting the eyes, nose, mouth, and ears. appear. Therefore, the second reason for focusing on the blood color is that it is possible to derive the position where the cheek makeup is to be derived according to the rules common to all people using the eyes, nose, mouth and ears as guidelines. Furthermore, the third reason for focusing on blood color is that the production of blood color is intended to be used by many people for cheeks and is a cheerful element that feels beautiful, so it meets the needs of many people. It is.

  In addition, the purpose of using teak was surveyed for 68 women in their 20s and 30s who usually make cheek makeup. As a result, the most frequently selected item was “To show the blood color well”. In addition, as a result of a questionnaire survey of 40 women in their twenties who usually do cheek makeup on the cheeks that they think are beautiful, the most frequently answered responses are “There is a beam”, “Moderately plump” and “Good blood” there were.

  In general, when applying makeup, a makeup base, foundation or the like is used to adjust the color unevenness of the bare skin. At this time, the natural color on the bare skin is almost erased. Therefore, it can be said that adding a blood color with a cheek makeup is a natural production method of regaining the original blood color element.

  The cheek makeup applied by beauty technicians is more beautiful than what ordinary people do on their own. This can be attributed to the fact that beauty technicians learn the characteristics of individual faces based on empirical rules and expertise, and learn how to make them look beautiful and have beautiful finishes. Therefore, we analyzed how to apply teak makeup by beauty technicians and tried to extract the laws.

  First of all, using facial photographs of 10 models with different cheek characteristics, we conducted a questionnaire to 27 beauty technicians, "If you want to express natural blood color with cheek makeup, how much will you blur around?" did. In addition, the center and range of the position where the cheek makeup was applied were directly written on the paper on which each face was printed.

  FIG. 68 is an image view for explaining an example of a cheek makeup according to the morphological characteristics of the subject's cheek. In FIG. 68, a line leading to the center of the cheek makeup is represented for a certain model (model A).

  First, the center position of the cheek makeup that expresses the blood color is near the center of the area connecting the eyes, nose, mouth, and ears. Furthermore, as a result of studying that the part is guided on the basis of an element that can easily identify the face, as shown in FIG. 68, an icicle (a part that is depressed when the mouth in front of the ear is opened) is connected with a line 2500 from the nose tip, When a line 2502 is drawn at the corner of the mouth from the point where the horizontal line 2501 drawn from the center of the face intersects the outline of the face, it was found that the intersection of both coincides with the answer of the beauty technician.

  Next, the range in which the cheek makeup is blurred will be described. The area where makeup is blurred is in the area connecting the eyes, nose, mouth and ears. Furthermore, this range falls within the parallelogram drawn using the line leading to the center to which the cheek makeup is applied.

  Specifically, first, a line (first line) 2503 drawn from the point where the horizontal line 2501 passing through the center of the eye drawn when guiding the center of the cheek makeup intersects the contour of the face is drawn down to the corner of the mouth in parallel. A line (second line) 2504 is provided. Further, a vertical line (third line) 2505 is drawn upward from the corner of the mouth, and the vertical line 2505 is moved in parallel until the horizontal line 2501 passing through the center of the eye intersects the contour of the face (fourth line). Line) 2506 is provided. In FIG. 68, these lines 2503 to 2506 can form a parallelogram. It can also be seen that the range of blurring the cheek makeup written by the beauty technician is within this parallelogram.

  Based on the above, it has become possible to derive the position of the starting point of cheeking for all faces and the standard of the range to blur using the eyes, mouth and nose, which are the three major elements that determine the face space. . In the following description, the position of the starting point for applying cheek makeup is referred to as “best point”.

  In other words, the starting point of the bloody color production cheek makeup is the intersection of the line connecting the licking from the tip of the nose, the horizontal line drawn from the center of the eye, and the line drawn from the point intersecting the face outline to the mouth corner. The range of blurring is a parallelogram drawn with the best point as a guideline. Specifically, a line is drawn to the tip of the nose from the intersection of the horizontal line passing through the center of the eye and the outline of the face, and then the line is lowered in parallel to the mouth corner. Furthermore, it is a parallelogram that is formed when a vertical line is drawn upward from the corner of the mouth and the vertical line is moved in parallel to a point where it intersects the horizontal line passing through the center of the eye.

  In this way, it was found that the best point of the starting point for applying the cheek and the range of blurring can be derived by a method common to all types.

  From the rule of thumb of beauty technicians, it was predicted that manipulating the shape of the cheek makeup taking into account the characteristics of the cheek would look good on the person and give a beautiful finish. Actually, even if the conditions of the starting point for applying the teak and the range to be blurred are satisfied, the finish may not be suitable.

  Therefore, the direction of adjustment was taken into account according to the cheek morphological characteristics, and the hypothesis was made that the shape of the cheek makeup was changed in accordance with the directionality. That is, adjustment is performed so that a person with a short cheek looks long, a person with a long skeleton feels short, and a person with a noticeable skeleton feels plump and a person with a fleshiness feels clear.

  Here, a questionnaire was conducted to verify the above hypothesis. In the questionnaire, two types of cheek makeup were applied to four models with different cheek morphological characteristics. One of the cheek makeups is “OK cheek”, which uses the rules of the standard of the best point and the range of blurring, and further changes the blur shape according to the cheek characteristics. The other is “NG teak” which is not considered in the form of blur. About these two types, the information of “OK” and “NG” was hidden, and general women (40 women in their 20s) evaluated them.

  Specifically, each photograph was viewed one by one, and the finish of each cheek makeup was evaluated on a bipolar 5-level scale. The evaluation items were “natural-unnatural”, “matched—not matched”, and the like. The average value of the evaluation of 40 people for the model of 4 people was calculated and examined.

  As a result of a statistical test for evaluation, it was found that “OK cheek” had a natural finish and a cheek three-dimensional appearance, and the flesh of the cheek looked slightly fluffier than “NG cheek”. This result also agrees with the above-mentioned beautiful cheek element, “Happy and moderately plump”. In addition, it was found that the balance of the whole face appears to be in order by applying this cheek makeup. In other words, with the “OK cheek” mentioned above, the cheeks can be seen three-dimensionally, you can feel the firmness of your skin softly, and restore the natural and healthy bloody beauty that the person originally has. Can do. In addition, the blood color production can adjust the balance while naturally drawing out the individual beauty. The shape of the cheek makeup applied to each model in the above questionnaire is based on the idea of adjusting the cheek length and the appearance of the skeleton and flesh.

  FIG. 68 shows the shape and range of cheek makeup according to cheek morphological characteristics. In FIG. 68, the cheek shape corresponding to the standard face is an inscribed ellipse 2507 inscribed in the parallelogram that is a standard.

Here, in the inscribed ellipse 2507 in FIG. 68, the long axis A is a straight line connecting the midpoints 2508-1 and 2508-2 of the vertical sides of the parallelogram as a guide for blurring, and the short axis B is the long axis A. The straight line is perpendicular to the midpoint 2509 and touches the upper and lower sides of the parallelogram. Further, when the half lengths of the axes A and B are a and b, the inscribed ellipse can be represented by (x ² / a ² ) + (y ² / b ² ) = 1. In the case of an average face, the relationship is a: b = 1: 0.55 ± 0.02.

  The method of blurring the cheek makeup is basically applied so that the starting point is the darkest and lightens toward the boundary of the blur shape, and the blur at the boundary part naturally dissolves into the skin.

(Eyebrow processing)
The eyebrow processing unit 37 included in the simulator main application 28 can be transformed into beautiful eyebrows suitable for every user's face by performing the eyebrow shape deformation process of step S80 in the first embodiment based on the following beauty theory.

  In general, a well-shaped eyebrow is known to comprise the following elements. 1. The eyebrow head starts just above the eye. 2. The eyebrows are on the extended line connecting the nose and the corners of the eyes. 3. Bizan is 2/3 from the eyebrows. Such eyebrows are said to be well-shaped. Further, these elements will be described in detail based on FIG.

  FIG. 69 is an explanatory diagram for explaining an ideal eyebrow shape. In FIG. 69, the eyebrow head 3003 is on the eyeline 3002 rising vertically from the eye 3001, and the eyebrow butt 3007 is on the nose eyebrow butt line 3006 inclined from the nose 3004 toward the eye corner 3005. A brow mountain 3010 exists on a vertical brow mountain line 3009 at a position of about 2/3 from the brow head 3003 to the brow butt 3007 of the brow base line 3008 to be connected (substantially coincides with the end of the white eye on the outer corner of the eye).

  Such an eyebrow is a well-shaped eyebrow, but from our recent research, there are many cases where a good-looking eyebrow does not look good even when drawn to various users, and other factors are involved. It has been found. And by adding the new elements, it has become possible to transform it into beautiful eyebrows that match the features of each person.

  The element is 4. 4. the position of the brow mountain 3010 on the entire face; By adding these new elements at an angle forming the brow mountain 3010 from the eyebrow head 3003, it can be transformed into a beautiful balanced eyebrow.

  Here, names of parts such as the eyebrow head 3003 and the eyebrow 3010 are used, but the eyebrow processing unit 37 includes the feature point (BR1) corresponding to the eyebrow head 3003 and the feature corresponding to the eyebrow mountain 3010 among the tracking points 34 described above. Use the point (BR2).

  Next, the position of a beautiful eyebrow that is balanced with the face will be described. For eyebrows balanced with the face, see 4. 4. the position of the brow mountain 3010 on the entire face; The angle forming the eyebrow 3010 from the eyebrow head 3003 is important. These points will be described with reference to FIG. FIG. 67 is an explanatory diagram for explaining the state of the position of the eyebrows.

  70A, 70B, and 70C represent positions occupied by the eyebrows with respect to the entire face. 70A, 70B, and 70C, the phantom horizontal line i indicated by the solid line is a line indicating the maximum width of the face when the face is viewed from the front. It becomes a line that touches. The vertical line B is an imaginary line when the horizontal line i indicating the maximum width of the face is set up vertically from the lower part of the chin. The horizontal line A and vertical line B intersect at a right angle at the approximate center of the face, and the ends of the horizontal line A and vertical line B are surrounded by sides represented by four dotted lines consisting of a, b, c, and d. A square is formed.

  Here, when viewing the position of the eyebrow in FIG. 70A, the eyebrow mountain 3010 of the eyebrow is in contact with the virtual square side a described above, and the eyebrows are in a beautiful position when viewed from the whole face, and the balance is achieved. I know that. In FIG. 70 (B), the eyebrows mountain 3010 of the eyebrows exists away from the virtual square side a, and the eyes, nose, and eyebrows are gathered at the center when viewed from the entire face, Looks short and unbalanced. In FIG. 70C, the eyebrows mountain 3010 protrudes from the virtual square side a, and when viewed from the whole face, the face looks long and the overall balance is not good.

  In general, a person with a round face is likely to have an eyebrows 3010 located below the side a as shown in FIG. 70B, and a person with a long face has a side a as shown in FIG. There are some cases in which Mt. Byu 3010 tends to pop out upward, and the tendency of these faces increases depending on how the eyebrows are drawn.

  Here, when the state of FIG. 70A is observed in detail, the angle forming the brow mountain 3010 from the brow head 3003 is about 10 degrees with respect to the brow base line 3008 connecting the brow head 3003 to the brow butt 3007. It is in contact with side a. In FIG. 70B, the angle forming the brow mountain 3010 from the brow head 3003 is about 5 degrees with respect to the brow base line 3008 connecting the brow head 3003 to the brow butt 3007, and the brow mountain 3010 is separated downward from the side a. Exist.

  In FIG. 70C, the angle at which the brow head 3003 forms the brow mountain 3010 is about 20 degrees with respect to the brow base line 3008 that connects the brow head 3003 to the brow butt 3007. It's popping out. It can be seen that the eyebrows in the state as shown in FIG. 70 (B) or (C) are drawn as close to the state as shown in FIG. 70 (A) as much as possible to obtain a beautiful eyebrow balanced with the face.

  The procedure for drawing the eyebrows will be described in more detail with reference to FIGS. 69 and 70. FIG. First, the maximum width of the front face of the subject's face (usually a straight line passing through the lower eyelid) is measured, and a virtual horizontal line i consisting of the width is created along the lower eyelid of the face. Next, a virtual vertical line B is created by setting the same length as the horizontal line A from the lowest point of the jaw, and the horizontal line A and the vertical line B are orthogonalized in front of the face. An imaginary square is formed by imaginary sides a, b, c, and d passing through the respective ends. The side a thus created is compared with the position of the patient's Meishan 3010, and it is determined whether the Meishan 3010 coincides with the square side a, is higher than the side a, or is lower.

  As shown in FIG. 70A, when the brow mountain 3010 coincides with the side a, the angle of the brow is often 10 degrees with respect to the brow base line 3008, so a reference line from the brow head 3003 to the brow mountain 3010 is set. . As the reference line, two points of the eyebrow head 3003 and the eyebrow mountain 3010 may be indicated by points with an eyebrow, or a thin line may be drawn. The reference line may be set on the lower side of the eyebrow, or on the center of the eyebrow and on the upper side of the eyebrow. In any of these cases, the brow mountain 3010 is on the brow mountain line 3009, and the brow is drawn so that the upper edge of the brow mountain 3010 is in contact with the side a. The eyebrows are drawn up to Mt. Mei 3010 with a certain width along the reference line, but from Mt. Mei 3010 to the eyebrow butt 3007, a free curve is made according to the preference of the patient to complete the eyebrow.

  Next, as illustrated in FIG. 70B, when the brow mountain 3010 comes to a position lower than the side a, the brow is drawn so that the position of the brow mountain 3010 is as close as possible to the side a. In this case, since the angle from the eyebrow head 3003 in FIG. 70B to the eyebrow mountain 3010 is as low as 5 degrees, in order to bring the eyebrow mountain 3010 closer to the side a, using an eyebrow scale having a depiction portion with an angle of 15 degrees, A reference line from the eyebrow head 3003 to the eyebrow mountain 3010 is set. However, in the case where the angle of the reference line becomes too large and deviates greatly from the position of the user's original Bizan 3010, the patient often feels uncomfortable. It is preferable to set a new Bizan 3010 above the Bizan line 3009 within a range of a maximum of 2 mm from the position. When a completely new eyebrow is drawn with the eyebrow shaved, such a restriction need not be provided. A guide line is drawn lightly with an eyebrow, and then drawn along the guide line from the eyebrow head 3003 to Mt. Meisho 3010, and an eyebrow butt 3007 is drawn to complete an ideal eyebrow. When the eyebrows are not shaved, the eyebrows can be drawn from the top of the original eyebrows as described above, and the protruding portions can be shaved and trimmed.

  In addition, as shown in FIG. 70C, when the brow mountain 3010 comes to a position higher than the side a, the brow is drawn so that the position of the brow mountain 3010 is returned to the side a as much as possible. In FIG. 70 (C), the angle from the eyebrow 3003 to the eyebrow 3010 is as high as 20 degrees, so a reference line from the eyebrow head 3003 to the eyebrow 3010 is set at an angle of 8 degrees. Even in this case, in the case where the subject is greatly displaced from the original position of the Meishan 3010, the subject often feels uncomfortable, and therefore, within a range of up to 2 mm from the position of the original Meishan 3010. It is preferable to set a new Bizan 3010 below the Bizan line 3009. If you draw your eyebrows in the same way as described above, you will have beautiful eyebrows that are balanced with the whole face.

  The face image can be adjusted by drawing the eyebrows connecting the eyebrow head 3003 and the Mt. For example, if you draw your eyebrows thickly, you will be "adult", if you draw your eyebrows thinly, you will be "pretty", if you draw your eyebrows linearly, you will be "clean", if you draw your eyebrows curvedly, Can be used properly according to the request of the patient.

  As described above, the eyebrow processing unit 37 included in the simulator main application 28 performs the eyebrow shape deformation process in step S80 in the first embodiment based on the beauty theory described above, so that the beautiful eyebrows suitable for every user's face can be obtained. Can be transformed.

(Foundation treatment)
The foundation processing unit 36 included in the simulation application 28 can also perform the following processing as preprocessing.

  A skin color evaluation process procedure as a pre-process of the foundation process will be described. FIG. 71 is a flowchart illustrating an example of a skin color evaluation processing procedure as preprocessing.

  In the skin color evaluation process shown in FIG. 71, first, an evaluation target image including a face imaged by an imaging unit such as a camera is input (S601), and the input face image is divided into a predetermined number by a preset division method ( S602). Note that the image obtained in S601 can be, for example, an image obtained by photographing a face that is uniformly illuminated as a whole with a photographing device such as a digital camera.

  Specifically, an illumination box for capturing face images under the same conditions is used, and in order to illuminate the face uniformly within the illumination box, a plurality of halogen bulbs are arranged in front of the illumination box, and the face is captured by a TV camera. , And acquire the captured face image. The image used in the present invention is not particularly limited to this, and an image taken in a general lighting environment such as a fluorescent lamp can be used.

  Next, a skin color distribution is generated from the image divided for each predetermined area (S603), and for example, a comparison skin color distribution is generated using various data stored in advance (S604). In addition, the skin color and the like are compared using the individual skin color distribution obtained in the process of S603 and the comparative skin color distribution obtained in the process of S604 (S605), and evaluation is performed using the skin color distribution profile (S606). . Further, a screen or the like to be displayed to the user or the like is generated from the evaluation result obtained by the process of S606 (S607), and the generated screen (evaluation result content or the like) is output (S608).

  Here, it is determined whether or not the skin color evaluation is to be continued (S609). When the skin color evaluation is to be continued (YES in S609), the process returns to the process of S602, and for example, division by a different division method from the previous time is performed. Perform the process. If the skin color evaluation is not continued in the process of S609 (NO in S609), the process ends. Next, the detail of the skin color evaluation process mentioned above is demonstrated.

<Face division processing: S602>
Next, the face division process described above will be specifically described. The face division process performs a predetermined division on a digital image including an input face. FIG. 72 is a diagram illustrating an example of feature points and divided areas. In FIG. 72, as an example, the entire face is divided into 93 areas, the average skin color of each divided area is obtained, the distribution of the face skin color is expressed by 93 skin color data, and the skin color is evaluated from the distribution and the like.

  By acquiring a lot of data for a certain part, which is an advantage of the conventional method, for example, the distribution range of Japanese women (which may be foreigners (other races) or men) at that part. An average value can be calculated, and as a result, individual skin color data can be evaluated by comparing with these indices. Further, for example, comparison of skin color before and after using cosmetics by the same person, comparison of skin color between two people with another person, and the like are also possible.

  Here, the division method shown in FIG. 72 has 109 feature points as an example. In addition, as an example, the divided regions shown in FIG. 72 are 93 regions (for example, indicated by numbers 1 to 93 in FIG. 72) having a triangular shape or a quadrangular shape constituted by three or four feature points. Area).

  FIG. 73 is a diagram showing an example of the positional relationship in the face of 109 feature points corresponding to FIG. 72 described above. FIG. 74 is a diagram showing an example of a combination of feature points constituting each region corresponding to FIG. 72 described above. 73, “No.” and “Name” of each feature point shown in FIG. 73 and “Area No.” and “Composition point” of each region shown in FIG. It corresponds to the contents shown in.

  Here, when setting the division contents, the face division processing is performed by first selecting, for example, No. 1 among the feature points shown in FIG. 1 to 37 feature points (for example, points indicated by “●” in FIG. 72) are set as the first feature points. The 37 feature points are, for example, 5 points in the forehead area, 10 points in the vicinity of the left and right eyes, 7 points in the nose, 9 points in the mouth, and 6 points in the face line below the eyes. It is preferable.

  Next, the face division processing is performed using, for example, No. 37 shown in FIG. Feature points 38 to 109 (for example, points indicated by “Δ” in FIG. 72) are set as the second feature points.

  For example, as shown in FIG. 1 to 37 predefined feature points 1 to 37, points 38 to 49 obtained by intersections of a plurality of straight lines passing between at least two of the feature points, and a line segment between the two points The points 50 to 57 and 67 to 109 that are internally divided by the ratio and points 58 to 66 that are on the straight line passing between the two feature points and have the same ordinate or abscissa as a particular point, etc. Points are earned.

  In addition, at least three of the first and second feature points (109 points) are divided into regions surrounded as constituent points as shown in FIG. The number of points constituting the region may be 3 or 4 as shown in FIG. 74, or may be 5 or more.

  Here, each area | region (area | region No. 1-93) shown in FIG. 72 is set so that it may become a physiologically meaningful division | segmentation based on the experience which observed many skin colors. That is, by setting as shown in FIG. 72, a portion where color unevenness is likely to occur is divided so that the region is narrowed, and a portion other than that is divided so that the region is widened.

  Specifically, in the division examples shown in FIGS. 72 to 74, for example, the forehead portion has a wide area to be divided, and the area around the eyes, the mouth, the cheeks, and the like has a narrow area. As described above, the divided areas to be set can be evaluated in more detail and with high accuracy by setting the area narrow for the important part (area) in evaluating the skin color.

  It should be noted that the divided areas can be aggregated (grouped) based on the degree of color or the like by determining in advance past data or the like what kind of skin color is likely to appear in each area. Thereby, it can evaluate easily for every group.

  Here, in the example of FIGS. 72 to 74 described above, the number of predefined feature points is 37 (No. 1 to 37), but is not limited to this. For example, at least 25 feature points ( The same division can be performed by setting the first feature point.

<Generation of face segmentation and facial skin color distribution map>
Next, generation of the face skin color distribution for the divided faces will be specifically described. An imaging device using a digital camera and an illumination device that uniformly illuminates the entire face is, for example, “Iwata et al. . ”Etc. will be described, but an example of generating a skin color distribution map for a face image acquired will be described. However, the method of capturing a captured digital image used in the present invention is not particularly limited to this. .

  A total of 109 feature points can be calculated by photographing the subject set at a predetermined position and designating, for example, 37 first feature points by face division processing as described above. In the face division process, the 109 feature points are divided into 93 regions according to the setting shown in FIG. 74 described above. In addition, this skin color distribution is determined for each region by tristimulus values X, Y, L *, a *, b *, Cab *, hab, and XYZ color systems in the L * a * b * color system. Each of Z, RGB values, hue H, lightness V, saturation C, melanin amount, and hemoglobin amount are used to generate an average value. In this case, for example, an L * a * b * color system, an XYZ color system, and three elements of hue H, lightness V, and saturation C are used to generate an image.

  Since the outside of the entire region and the portion that is not skin color in the region are not subject to evaluation, for example, they are colored with a specific color such as a cyan color far away from the skin color. Further, detailed information on the skin disappears, and the distribution of the facial skin color is easily grasped. For example, the feature of model A “skin color around eyes” is known. In the skin color evaluation process, the peripheral part of the photographed face may have low illumination uniformity. Therefore, the data on the peripheral part can be excluded in the skin color distribution evaluation process.

  In addition, when the “average face” is divided into regions by the same method and each region is colored with 93 skin colors of the obtained model A, pure color information excluding model face shape information can be grasped. it can.

  By performing the above-described processing, evaluation can be performed based on the divided areas, so that the face shape information of a person can be excluded, and comparison of skin color distribution between people having different face shapes can be easily performed. Therefore, taking advantage of this feature, for example, the facial skin color distribution of Model A can be evaluated by comparing with the average value of the same age.

<Generation Example of Comparison Skin Color Distribution: S604>
Next, an example of generating a comparison facial skin color distribution in the skin color distribution evaluation process will be described. As an average skin color distribution for each age, a face image in which a person of a corresponding age is photographed is decomposed into regions, and then, for example, L *, a *, b *, Cab *, L * a * b * color system Skin color by average value using at least one of tristimulus values X, Y, Z, RGB values, hue H, lightness V, saturation C, melanin amount, and hemoglobin amount in hab, XYZ color system A distribution is obtained, and an average skin color distribution is obtained by calculating an average value for each age.

  In addition, each area | region of an average face is colored using the data of the average skin color distribution of the Japanese woman of each age from the 20s to 60s which were calculated | required. Thus, by displaying in a straight color, an average skin color distribution for each age can be generated, and by comparing with this data, highly accurate skin color evaluation of the evaluation target image can be performed.

<Comparison of skin color distribution>
Next, a comparative example of skin color distribution will be specifically described. In the skin color distribution evaluation process, the skin color distribution is compared by taking the difference. The facial skin color distribution can be grasped by dividing the face image into predetermined areas, and by replacing the color with a standard face such as an average face, it is possible to express only the color information excluding the face shape. It becomes. The average value data of people belonging to a certain category (age, occupation, gender), ideal person data such as talents, past data of individuals, data of others, etc. Since it becomes possible, it can be used for counseling when selling cosmetics.

<Skin color distribution aggregation (grouping) and skin color distribution profile generation example>
Here, in the present embodiment, the skin color distribution evaluation process aggregates (groups) areas having similar color tendencies in the skin color area by analyzing past data and the like and obtaining principal components. be able to. Thereby, it can evaluate easily for every group. FIG. 75 is a diagram showing an example of the color characteristics of each group and the area numbers constituting each group. Note that the feature points constituting the region indicated by 75 correspond to FIGS. 72 to 74 described above.

  In the example shown in FIG. 75, the part (1) cheek bottom, (2) cheek front, (3) eyelid / bear part, (4) forehead, (5) nose circumference, (6) mouth circumference are grouped. . In addition, as a characteristic of color, “(1) cheek bottom” is high brightness, “(2) cheek front” is slightly brighter than red, and “(3) eyelid / bearing part” is yellowish. Slightly low brightness, "(4) Forehead" is slightly brighter than yellow, "(5) Nose circumference" is slightly less bright than red, and "(6) Mouth circumference" is reddish More low brightness.

  Here, as an example, a principal component analysis of hue H was performed on 57 effective regions excluding 4 regions of lips in 59 people aged 20 to 67 years, and as a result, 90. 1% was found to be accountable.

  Therefore, 57 regions based on the above-mentioned main components described above (1) cheek bottom, (2) cheek front, (3) eyelid / bearing part, (4) forehead, (5) nose circumference, (6) Classify into 6 types around the mouth. The skin color distribution can also be evaluated by the balance of the main component scores (skin color profile).

  Next, a face classification process procedure as a pre-process of the foundation process will be described. Here, in order to adjust the three-dimensional effect and extract a method for producing beauty, we examined what three-dimensional effect is evaluated as beautiful. In the study, (a) a real face, (b) a natural-looking base makeup with natural skin color unevenness, and (c) an egg-shaped base makeup that adjusts the three-dimensional effect so that the entire face looks like the balance of the average face. Use the face.

  Here, the three types of base makeup (a) to (c) described above are applied to six models with different facial features, and the results of questionnaires for 20 women in their 20s are used. Carried out.

  Eight items related to the appearance of the face (how to see the sun, three-dimensional appearance of the sun, how it fits the nose, with the flesh of the cheek, the length of the cheek, the face line, the appearance of the chin, the balance of the eyes and nose), and the solid face Evaluations were made on three items related to the overall impression of feeling, beauty, and preference (three-dimensionality of the entire face, beauty, and preference). He also asked us whether he was able to see his face properly.

  As a result, it was found that by applying the base make-up, the balance of the eyes and nose stands up and looks three-dimensional. The appreciation of beauty and taste has also increased. The rating was highest for egg-type base makeup. It became clear that adjusting the three-dimensional effect to the egg-shaped base improves the evaluation of the face more than the real face or the face-like base. Furthermore, a detailed analysis of the egg-shaped base makeup revealed that the base makeup was applied so that an ellipse similar to the average face contour shape emerged inside the face passing through the eyebrows.

<Examination based on standard balance>
Common beauty face conditions include egg-shaped face lines and golden balance. In the golden balance, for example, the eye position is about 1/2 of the total head height, and from the hairline to the chin, the eyebrow head is 1/3 from the hairline, and the nose is 2/3 from the hairline. To position.

  Here, it is known that the balance of the “average face” created by averaging the size information and color information of a plurality of face photographs by a conventional image composition technique etc. approaches the value of this golden balance. Yes. In addition, it is shown that the use of 10 people for the creation of the average face is almost the same as the one made from 10 different face photos (for example, Miwa Nishitani et al. Searching for features ”, The Psychological Collection of the 63rd Annual Meeting of the Japanese Psychological Association, published in August 1999) The “average face” created using face photographs for 40 women satisfies the golden balance described above. In the following, this golden balance will be the standard balance.

  In addition, referring to a face photo from which the depth and skeletal flesh information has been removed from the “average face” (excluding skin color information), it can be seen that the depth and skeletal flesh feel greatly affect the facial impression. . Further, when the above-described image analysis (monochrome posterization processing) was performed on the average face, it was found that an egg shape similar to the face line could be extracted inside the face line.

  Here, FIG. 76 is a diagram illustrating an example of an average face image (or stereoscopic effect) analysis result. As shown in FIG. 76, a face line (inner face line) 4001 in which the outer face line 4000 is similarly reduced also exists inside the outer face line (outer face line) 4000 corresponding to the face line of the face. all right. From this, it was shown that showing the three-dimensional effect inside the face in an egg shape is one of the new ways to produce beauty.

<Adjustment of stereoscopic effect-Best oval adjustment method>
Next, an adjustment hypothesis was made in order to create a three-dimensional feeling inside the face line, that is, a beauty method for arranging the inner face line into an egg shape. Here, the shape of the outer face line and the inner face line obtained with the average face is defined as “best oval”. The outer face line has an oval shape (standard outer face line) having a width to length ratio of approximately 1: 1.4. The inner face line of the “average face” is similar to the standard outer face line, and has a shape reduced at a predetermined ratio, and the horizontal width to vertical width ratio is approximately 1: 1.4.

  As described above, the outer face line 4000 has a shape indicated by the relationship of “width of the face: length ratio = 1: 1.4”. The outer face line balance is a point for determining the direction of the entire face space adjustment. When the inner face line 4001 is applied to each face, the lateral width of the left and right cheeks of each face is set to 1 as shown in FIG. Next, a standard inner face line 4001 having a vertical width of about 1.4 based on the horizontal width, that is, a best oval is drawn, and touches the eyebrows of each face (on the extension line passing from the side of the nose to the corner of the eye). Position. The inner face line balance is an adjustment zone for the three-dimensional effect and space due to the skeleton and flesh.

  Further, a zone (hatched portion in FIG. 76) 4002 that gives a natural depth feeling is formed between the outer face line 4000 and the inner face line 4001. The zone 4002 is a depth adjustment zone in which the depth of the outer face line 4000 and the inner face line 4001 is adjusted and shown at the same time as the depth is increased.

  The pretreatment of the foundation process described above can be used for base makeup.

  As described above, according to the present invention, makeup can be accurately applied to a user's face included in a moving image with a small processing load. The photographing means described in the claims corresponds to the camera 2, the control means corresponds to the control unit 8, the display means corresponds to the monitor 7, and the face recognition processing means corresponds to the face recognition processing unit 33. The makeup processing means corresponds to the makeup processing unit 35, the operation means corresponds to the operation panel 4, the half mirror means corresponds to the half mirror 3, and the printing means corresponds to the printer 5.

  Further, the present invention is not limited to the specifically disclosed embodiments, and various modifications and changes can be made without departing from the scope of the claims.

  Since the makeup simulation apparatus 1 of the present invention is a real-time simulation, unlike the one based on a still image or the conventional makeup simulation apparatus 1, the face tracking point is instantly recognized, and the simulation is performed based on the tracking point. Since it can, it also enables the following things that were not possible before.

  The makeup simulation apparatus 1 of the present invention can perform real-time simulation. Since the makeup simulation apparatus 1 of the present invention can perform simulations not only from the front face but also from the side face as before, it is easy to check the simulation effect and technique such as blusher.

  Since the makeup simulation apparatus 1 of the present invention is a real-time simulation, it has become possible to analyze a face as a three-dimensional object and to express a three-dimensional feeling and texture from the conventional planar expression.

  In addition, since the makeup simulation apparatus 1 of the present invention can recognize a number of faces at the same time, a number of real-time simulations are possible at the same time. Since the makeup simulation apparatus 1 according to the present invention has an excellent face recognition function, makeup according to each feature or classification can be made according to each feature or automatically classifying men and women. For example, the makeup simulation apparatus 1 of the present invention is capable of performing each makeup simulation simultaneously with a couple.
