Abstract

An apparatus for obtaining an antioxidant index may include an image acquirer configured to acquire an image by capturing a correction reference object and a skin of a user and a processor configured to determine a first degree of yellowness of the correction reference object and a second degree of yellowness of the skin based on the image, and determine an antioxidant index of the user based on the first degree of yellowness and the second degree of yellowness.

First claim

What is claimed is:

1. An apparatus for obtaining an antioxidant index, comprising:
an image acquirer configured to acquire an image in which a correction reference object and a skin of a user are captured; and
a processor configured to determine a first degree of yellowness of the correction reference object and a second degree of yellowness of the skin based on the image, and configured to determine an antioxidant index of the user based on the first degree of yellowness, the second degree of yellowness, and a predetermined antioxidant index estimation model, the predetermined antioxidant index estimation model defining a relationship between the antioxidant index and at least one of a difference between the first degree of yellowness and the second degree of yellowness or a ratio between the first degree of yellowness and the second degree of yellowness.

2. The apparatus of claim 1 , wherein the image acquirer is configured to acquire the image by capturing the correction reference object and the skin by using a camera.

3. The apparatus of claim 1 , wherein the processor is configured to analyze the image based on an International Commission on Illumination (CIE) chromaticity analysis.

4. The apparatus of claim 3 , wherein the processor is configured to determine a b-value related to the first degree of yellowness and a b-value related to the second degree of yellowness.

5. The apparatus of claim 1 , wherein the processor is configured to obtain at least one of the difference between the first degree of yellowness and the second degree of yellowness or the ratio between the first degree of yellowness and the second degree of yellowness, and configured to determine the antioxidant index based on the at least one of the difference or the ratio and the predetermined antioxidant index estimation model.

6. The apparatus of claim 1 , wherein the processor is configured to control to output information for guiding an action of the user prior to acquiring the image through a camera.

7. The apparatus of claim 1 , further comprising a noise remover configured to remove noise from the acquired image.

8. The apparatus of claim 1 , wherein the image acquirer is configured to acquire the image from an external device communicatively connected to the apparatus.

9. The apparatus of claim 1 , wherein the correction reference object comprises an object in yellow color.

10. A method of obtaining an antioxidant index, comprising:
acquiring an image in which a correction reference object and a skin of a user are captured;
determining a first degree of yellowness of the correction reference object and a second degree of yellowness of the skin based on the image; and
determining an antioxidant index of the user based on the first degree of yellowness, the second degree of yellowness, and a predetermined antioxidant index estimation model, the predetermined antioxidant index estimation model defining a relationship between the antioxidant index and at least one of a difference between the first degree of yellowness and the second degree of yellowness or a ratio between the first degree of yellowness and the second degree of yellowness.

11. The method of claim 10 , wherein the acquiring comprises acquiring the image by capturing the correction reference object and the skin using a camera.

12. The method of claim 10 , wherein the determining the first degree of yellowness and the second degree of yellowness comprises analyzing the image based on an International Commission on Illumination (CIE) chromaticity analysis.

13. The method of claim 12 , wherein the determining the first degree of yellowness and the second degree of yellowness further comprises determining a b-value related to the first degree of yellowness and a b-value related to the second degree of yellowness.

14. The method of claim 10 , wherein the determining the antioxidant index comprises:
obtaining at least one of the difference between the first degree of yellowness and the second degree of yellowness or the ratio between the first degree of yellowness and the second degree of yellowness; and
determining the antioxidant index based on the at least one of the difference or the ratio and the predetermined antioxidant index estimation model.

15. The method of claim 10 , further comprising controlling to output information for guiding an action of the user prior to acquiring the image through a camera.

16. The method of claim 10 , further comprising removing noise from the acquired image.

17. The method of claim 10 , wherein the acquiring comprises acquiring the image from an external device.

18. The method of claim 10 , wherein the correction reference object comprises an object in yellow color.
