Abstract: The present disclosure improves the accuracy of blood flow assessment. According to one embodiment of the present invention, a blood flow assessment device has: a measurement part configured to measure skin temperatures at a plurality of locations on a face of a user; a calculation part configured to calculate a variation of the skin temperatures at the plurality of locations; and a blood flow assessment part configured to assess a blood flow of the user based on the variation.

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: An information processing apparatus that executes a simulation that predicts future skin condition when cosmetics are used on the skin. The apparatus retrieves target person skin information regarding simulation target person's skin, predicts transition of skin condition of the simulation target person by inputting the target person's skin information to condition transition model relating to the skin condition transition based on subject skin information indicating the time course of the skin when each of the plurality of subjects uses the cosmetic on the skin, subject condition information regarding the subject's skin condition corresponding to each subject's skin information, and cosmetic information regarding the cosmetic, and presents the predicted skin condition transition.
