Abstract

An advanced cosmetic color analysis system (FIG. 1) analyzes the color of a three dimensional object (element 120) to produce a plurality of color values for distinct subsets of a portion of the object, and a cosmetic analyzer (element 150) combines the color values to produce a cosmetic color determination that has relative weightings of multiple cosmetic colors. Contemplated systems are particularly useful for determination of suitable cosmetic products (or composition thereof) to achieve a particular and desired cosmetic appearance.

Claims

1. A system comprising:

a collector that captures light as a field of pixels reflecting off of a three dimensional object;

a color analyzer that uses data from the pixels to produce a plurality of color values for each of a plurality of distinct subsets of the field, wherein each distinct subset comprises more than one pixel; and

a cosmetic analyzer that then combines the plurality of color values from the subsets to produce a cosmetic color determination comprising relative weightings of a plurality of cosmetic colors.

2. The system of claim 1 wherein the collector is coupled to a digital video camera or a digital still camera.

3. The system of claim 1 wherein the three dimensional object is selected from the group consisting of a hair, a plurality of hair, and a portion of facial skin.

4. The system of claim 1 wherein the data from the pixels are encoded in an RGB system or a CMYK system.

5. The system of claim 4 wherein the data further comprise at least one of a hue value, a saturation value, and a luminance value.

6. The system of claim 1 wherein the plurality of color values is calculated as a frequency of predetermined color combinations.

7. The system of claim 1 wherein the plurality of distinct subsets of the field is at least ten distinct subsets.

8. The system of claim 1 wherein at least one of the plurality of distinct subsets of the field is defined by a user.

9. The system of claim 1 wherein the pixels in the plurality of distinct subsets of the field are contiguous.

10. The system of claim 1 wherein the cosmetic color determination comprising relative weightings of between and including two and four cosmetic colors.

11. The system of claim 1 wherein the cosmetic color is expressed in a descriptive cosmetic term.

12. The system of claim 1 wherein the collector is coupled to a light source that emits broad band light.

13. The system of claim 1 wherein the three dimensional object comprises hair and wherein the cosmetic color determination further comprises identification of a commercially available hair coloring product to achieve a predetermined coloration.

14. The system of claim 1 wherein the three dimensional object comprises hair and wherein the cosmetic color determination further comprises prediction of a hair color resulting from use of a commercially available hair coloring product.

15. The system of claim 1 wherein the three dimensional object comprises hair and wherein the cosmetic color determination further comprises calculation of a composition of a hair coloring product to achieve a predetermined coloration.

16. The system of claim 14 wherein the composition of the hair coloring product includes at least one color and an undertone.

17. The system of claim 1 wherein the collector is optically coupled to a magnifying device.

18. The system of claim 17 wherein the three dimensional object comprises a single hair or a strand of hair, and wherein the cosmetic color determination further comprises determination of a hair color distribution in the single hair or strand of hair.

19. The system of claim 17 wherein the cosmetic analyzer further combines the plurality of color values from the subsets to produce a hair condition determination.

20. The system of claim 19 wherein the hair condition determination includes determination of at least one of waviness, curliness, thickness, and integrity of at least one hair.

21. The system of claim 1 wherein the three dimensional object comprises hair and wherein the cosmetic color determination further comprises recommendation of a commercially available hair care product to achieve a desired outcome.

22. The system of claim 21 wherein the hair care product is a conditioner or a shampoo.

23. The system of claim 22 wherein the hair care product is commercially available from a supplier other than a supplier that provides the system.

24. The system of claim 1 further comprising a storage medium electronically coupled to the cosmetic analyzer, wherein the storage medium stores at least one of usage history and results history.

25. The system of claim 1 further comprising a storage medium electronically coupled to the cosmetic analyzer, wherein the storage medium stores personal information of a user.
