Abstract

Provided is an image processing device including a dividing unit which divides a captured image of skin into regions in a multidimensional manner, a feature value calculating unit which calculates a feature value of a color property in each region divided by the dividing unit, and an evaluating unit which calculates an evaluation value of the skin using the feature values calculated by the feature value calculating unit.

Claims

1. An image processing device comprising:

a dividing unit which divides a captured image of skin into regions in a multidimensional manner;

a feature value calculating unit which calculates a feature value of a color property in each region divided by the dividing unit; and

an evaluating unit which calculates an evaluation value of the skin using the feature values calculated by the feature value calculating unit.

2. The image processing device according to claim 1,

wherein the dividing unit performs the division in at least one of a planar direction and a depth direction.

3. The image processing device according to claim 1,

wherein the dividing unit divides the captured image of the skin into a skin region and a non-skin region.

4. The image processing device according to claim 3,

wherein the dividing unit divides, as the non-skin region, at least one of a pore region, a spot region, and a body hair region.

5. The image processing device according to claim 3,

wherein the dividing unit divides the skin region based on each component of the skin.

6. The image processing device according to claim 1,

wherein the color property is at least any one of skin brightness and skin transparency.

7. The image processing device according to claim 1,

wherein the evaluating unit weights the feature value calculated in each region, and then calculates an evaluation value of the skin using the weighted feature values.

8. The image processing device according to claim 1,

wherein the feature value calculating unit and the evaluating unit perform exclusion processing of excluding a greatly different value, and then calculate the feature value and the evaluation value.

9. The image processing device according to claim 2,

wherein the dividing unit obtains captured images at different positions in the depth direction generated while controlling a polarization plane of a light source and an imaging unit which generates the captured images, obtains captured images at different positions in the depth direction generated while controlling a focal length of the imaging unit, or generates captured images at different positions in the depth direction from an intensity distribution and traveling direction information of light to thereby preform the division of the regions in the depth direction.

10. An image processing method comprising:

a step of dividing a captured image of skin into regions in a multidimensional manner;

a step of calculating a feature value of a color property in each divided region; and

a step of calculating an evaluation value of the skin using the calculated feature values.

11. A program which causes a computer to execute skin evaluation, wherein the program causes the computer to execute:

processing of dividing a captured image of skin into regions in a multidimensional manner;

processing of calculating a feature value of a color property in each divided region; and

processing of calculating an evaluation value of the skin using the calculated feature values.

12. An image processing system comprising:

an imaging device and an information processing device,

wherein the imaging device includes an imaging unit of generating a captured image of skin, and

either the imaging device or the information processing device includes a dividing unit which divides the captured image of the skin into regions in a multidimensional manner,

a feature value calculating unit which calculates a feature value of a color property in each region divided by the dividing unit,

an evaluating unit which calculates an evaluation value of the skin using the feature values calculated by the feature value calculating unit, and

a presentation unit which presents an evaluation result based on the evaluation value of the skin.
