摘要: Provided is a method and an apparatus thereof for measuring a skin characteristic. The apparatus comprises a processor configured to receive, over a time period T, a first response indicating intensities of light of a first wavelength λ 1 reflected from skin, and a second response indicating intensities of light of a second wavelength λ 2 reflected from the skin. It further receives a first indication of a total intensity of the light corresponding to the first response and a second total intensity of light corresponding to the second response, which are emitted to the skin over the time period T. A first variation curve (10) with the first response as a function of the first indication and a second variation curve (11) with the second response as a function of the second indication is determined. The processor further determines a portion of each variation curve, along which portion the variation is substantially linear. It then calculates slopes at at least one point in said portion of the variation curves, and determines a value of the skin characteristic from a ratio of the slopes.

摘要: According to an aspect, there is provided a method for determining a value of a skin parameter for skin of a subject. The method comprises receiving (510) a first sensor signal that is output by a first light sensor that is arranged to receive light emitted by a first light source after interaction of the emitted light with the skin. The first sensor signal is output while the first light source operates according to a first duty cycle to intermittently emit the light, and the emitted light has a first central wavelength. The method also comprises receiving (520) a first modulation reference signal that is related to the first duty cycle; integrating (530) a first function output signal, resulting from a function of the first sensor signal and the first modulation reference signal, to determine a first integrated value; determining (540) a first number of cycles of the emitted light that are required for the first integrated value to exceed a first threshold value; and determining (550) the value of the skin parameter based on the determined first number of cycles.

摘要: There is provided a system for performing ambient light image correction. The system comprises a light source, a rolling shutter imaging unit configured to capture a plurality of images of the object at an exposure time shorter than the wave period of the pulsed illumination from the light source, and a control unit configured to generate a first composite image comprising a plurality of bright bands from the plurality of captured images by combining sections from the plurality of captured images which correspond to bright bands, generate a second composite image comprising a plurality of dark bands from the plurality of captured images by combining sections from the plurality of captured images which correspond to dark bands, and generate an ambient light corrected image based on a difference in pixel information between the first composite image and the second composite image.
