Abstract

A lip categorizing method uses the size and shape of the lips as viewed from the front of the face as a first categorization index and the three-dimensional form of the lips as a second categorization index. The lip categorizing map is composed of a first coordinate axis showing the degree of the first categorization index and a second coordinate axis showing the degree of the second categorization index and has a coordinate system in which the first and second coordinate axes are orthogonal. It also generates makeup information for two-dimensionally correcting the lips of a subject based on preset reference by setting a plurality of points for determining the form features of lips on an image that depicts the lips, and judges the form features of the lips of the subject based on analytical values of the two-dimensional features of the lips measured from the set points.

Claims

1. A lip categorizing method comprising:

categorizing lips using the size and shape of lips as viewed from the front of a face as a first categorization index and using the three-dimensional form of the lips as a second categorization index, in order to enable determination of a form image of the lips.

2. The lip categorizing method according to claim 1, wherein the first categorization index includes as indices at least the lateral width of the lips, the form of the crests and trough of the lips, and the form of the bottom of the lower lip, while the second categorization index includes as indices at least whether the contour shape of the lips is linear or curved, and the three-dimensional form of the lips.

3. A lip makeup method comprising:

when applying makeup to lips, drawing contour lines of the lips by applying a technique for adjusting the form of the lips and applying the makeup based on the contour lines.

4. The lip makeup method according to claim 3, wherein a technique for making a plurality of adjustments comprises the five steps indicated below:

step 1;

the crests of the lips are positioned at vertical lines extending downward from the center of the nostrils;

step 2;

the shape of the bottom of the lower lip is aligned with the shape of the tip of the jaw;

step 3;

the shape of the lower lip is made to be substantially parallel with the jaw line;

step 4;

the line connecting the corners of the mouth is tightened; and

step 5;

the angle from the trough to the crests of the upper lip is made to be within the range of 10 to 15 degrees.

5. The lip makeup method according to claim 3, wherein the ratio of the upper and lower lips is made to be within the range of 1:

1.3 to 1;

1.5.

6. The lip makeup method according to claim 3, wherein the adjustment range between the inherent lip contour lines and the drawn contour lines is within 2 mm.

7. A lip categorizing map comprising:

a first coordinate axis showing the degree of a first categorization index using as indices the size and shape of the lips as viewed from the front of the face; and

a second coordinate axis showing the degree of a second categorization index using as indices the three-dimensional form of the lips,

the determination of a form image of the lips being allowed by composing a coordinate system in which the first and second coordinate axes are orthogonal.

8. The lip categorizing map according to claim 7, wherein lips having a standard form are located in the center of the coordinate system.

9. The lip categorizing map according to claim 7, wherein the first categorization index includes as indices at least the lateral width of the lips, the form of the crests and trough of the lips, and the form of the bottom of the lower lip, while the second categorization index includes as indices at least whether the contour shape of the lips is linear or curved, and the three-dimensional form of the lips.

10. A lip makeup tool comprising a scale extending in two directions in a V-shape along the form of the trough and crests of the upper lip,

the shapes of the trough and crests of the upper lip being allowed to be drawn by aligning the V-shaped trough with the trough of the upper lip and aligning the scale with the crests.

11. The lip makeup tool according to claim 10, wherein a handle is connected to one end of the scale.

12. The lip makeup tool according to claim 10, wherein the angle of the V shape of the scale can be adjusted to within the range of 10 to 15 degrees.

13. A lip makeup tool comprising a scale extending in two directions in a V-shape along the contour line of the lower lip,

the contour line of the lower lip being allowed to be drawn along the scale by aligning a V-shaped trough with the center of the lower edge of the lower lip and positioning the scale by aligning with the jaw line.

14. The lip makeup tool according to claim 13, wherein a handle is attached to the center of the V-shaped scale extending downward.

15. The lip makeup tool according to claim 13, wherein the scale is adjustable to a desired angle.

16. The lip makeup tool according to claim 13, wherein the angle of the scale is fixed.

17. A lip makeup method comprising:

generating makeup information for two-dimensionally correcting the lips of a subject based on preset reference by setting a plurality of points for determining the form features of lips on an image depicting the lips, and judging the form features of the lips of the subject based on analytical values of the two-dimensional features of the lips measured from the set points.

18. The lip makeup method according to claim 17, wherein in addition to analysis of two-dimensional features of the lips, the three-dimensional appearance of the lips is determined by analyzing three-dimensional features of the lips according to brightness values of the image.

19. The makeup method according to claim 17, wherein the points used to determine form features of the lips comprise the position of the nose, the center positions of the nostrils, the positions of the crests and trough of the upper lip, the center position of the lips, the positions of the corners of the mouth, the center position of the lower lip, and the position of the jaw.

20. The lip makeup method according to claim 17, wherein the reference for generating makeup information for two-dimensionally correcting the lips comprise the five parameters indicated below:

parameter 1;

reference for indicating the positions of the corners of the mouth;

parameter 2;

reference for indicating the position of the upper lip;

parameter 3;

reference for indicating the position of the lower lip;

parameter 4;

reference for indicating the positions of the crests of the upper lip; and

parameter 5;

reference for indicating the position of the trough of the upper lip.

21. The makeup method according to claim 19, wherein the reference for indicating the positions of the corners of the mouth is defined as the positions determined based on the center of the lips.

22. The makeup method according to claim 19, wherein the reference for indicating the position of the upper lip is defined as the position one-third the distance from the oral slit to beneath the nose.

23. The makeup method according to claim 19, wherein the reference for indicating the position of the lower lip is defined as the position one-third the distance from the oral slit to the position of the jaw.
