To appropriately evaluate skin spots by grasping a quality (characteristic) of the skin spots. A skin spot evaluation apparatus includes an area extracting unit that extracts skin spot areas corresponding to skin spots from a skin image obtained by photographing a skin of a subject; and an evaluation unit that analyzes, based on the skin spot areas extracted by the area extracting unit, at least one of the number of the skin spots, dimension of each of the skin spots and density of each of the skin spots, and generates data obtained by quantifying characteristic of the skin spots of the skin image using the analyzed result.

Skin spot evaluation apparatus, skin spot evaluation method and program

An evaluation method of evaluating a color irregularity site (a blemish) includes a color irregularity site detection step (step S) of detecting a plurality of color irregularity sites respectively from a first skin image and a second skin image different from the first skin image, a gravity center position calculation step (step S) of calculating gravity center positional coordinates of the color irregularity sites respectively for the first skin image and the second skin image, and a matching process step (step S) of matching the plurality of color irregularity sites included in the first skin image with the plurality of color irregularity sites included in the second skin image based on the calculated gravity center positional coordinates of the color irregularity sites.

Evaluation method for site of color irregularity and color irregularity site evaluation apparatus

A skin dullness evaluation apparatus includes a frequency analyzing unit that decomposes a skin image into color heterogeneity of a predetermined size; a color heterogeneity index obtaining unit that obtains color data of skin from each of the color heterogeneity decomposed by the frequency analyzing unit, and obtains a color heterogeneity index of the color heterogeneity from the obtained color data of skin; and a dullness evaluation unit that evaluates skin dullness corresponding to the skin image based on the color heterogeneity index obtained by the color heterogeneity index obtaining unit.

Skin dullness evaluation apparatus and skin dullness evaluation method

There is provided a lighting device for capturing a facial image of a subject by an image capturing unit in plural different near-infrared regions of light including a housing in which a substantially spherical space is formed by a spherical surface, the housing accommodating an entire face part of the subject; at least two light sources arranged at positions bilaterally symmetrical with the subject on the spherical surface to emit the light to light the substantially spherical space; an image capturing unit capturing an image of the entire face part; a first filter installed in front of the light source to block ultraviolet rays and infrared rays from the emitted light; a second filter installed in front of the lens to adjust an amount of the light, and a third filter installed in front of the lens to perform band-pass filtering corresponding to the different near-infrared regions.
