Abstract: 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.

Abstract: An image analysis device according to the present invention includes: an image capturing unit that captures a subject; a light emitting unit that emits light to the subject; a sensor unit that senses an inclination of the image capturing unit relative to the subject; a control unit that causes the image capturing unit to capture an image of the subject while controlling light emission of the light emitting unit; and a determination unit that, based on a positional relationship of the image capturing unit and the light emitting unit and the inclination, determines a measurement region spaced apart by a predetermined distance from a reflection region corresponding to a position in the image where a light from the light emitting unit regularly reflects at the subject.

Abstract: An image analysis device according to the present invention includes: an image capturing unit that captures a subject; a light emitting unit that emits light to the subject; a control unit that causes the image capturing unit to capture a first image of the subject while causing the light emitting unit to emit light and causes the image capturing unit to capture a second image of the subject while not causing the light emitting unit to emit light; and an estimation unit that estimates color of the subject based on a differential value between color information on the first image and the color information on the second image.

Abstract: 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.

Abstract: Provided are an evaluation method for objectively evaluating the glow of the skin, a skin glow improver, and a method for examining skin glow improvers. This method for evaluating the glow of the skin comprises assessing the specular reflectance and diffuse reflectance of skin after polarized light is applied to the surface of the skin, and determining that glow is present in the skin when prescribed conditions are satisfied. A skin glow improver is provided by combining an alkali metal salt of alkoxysalicylic acid and trimethylglycine. This method for examining skin glow improvers makes it possible, using a significant decrease in surface roughness as an indicator, to examine samples capable of improving the specular reflectance of the skin.
