摘要： There is provided a system (10) for measuring skin pores. The system (10) comprises a device (100). The device (100) comprises a light source (104) configured to emit light (106) to illuminate skin (102) with an angle of incidence in a range from 40 to 80 degrees. The device (100) comprises an imaging sensor (108) configured to detect light (110) reflected from the skin (102) and convert the detected light (110) into an image of the skin (102). The system comprises a processor (111) configured to acquire the image of the skin (102) from the imaging sensor (108) and process the acquired image to measure skin pores.

摘要： According to an aspect, there is provided an apparatus for obtaining images for use in determining one or more properties of skin of a subject, the apparatus comprising an image sensor unit for generating an image of a skin sample, wherein the skin sample corresponds to an area of skin of the subject within a field of view, FOV, of the image sensor unit when the skin of the subject is spaced a predetermined working distance from the image sensor unit; a first light arrangement comprising one or more light sources for illuminating the skin of the subject; and a second light arrangement comprising one or more light sources for illuminating the skin of the subject. The one or more light sources in the first light arrangement are spaced from the image sensor unit and arranged such that light emitted by the light sources in the first light arrangement that is specularly reflected by a skin sample at the predetermined working distance is incident on the image sensor unit, and the one or more light sources in the second light arrangement are spaced from the image sensor unit and arranged such that light emitted by the light sources in the second light arrangement that is specularly reflected by a skin sample at the predetermined working distance is not incident on the image sensor unit.
