摘要： One or more display color characteristics of an electronic device are managed using a light detecting sensor configured to output multiple color channels in a predefined color space. The light detecting sensor in the electronic device senses ambient light and outputs measurements in visible color channels of the predefined color space to characterize the sensed ambient light. A ratio of one or more measurements of one of the visible color channels to one or more measurements of another of the visible color channels is determined. At least one light source generating at least a portion of the sensed ambient light is classified based at least in part on the determined ratio, wherein the determined ratio indicates a color temperature component of the sensed ambient light. The one or more display color characteristics of the electronic device are adjusted based at least in part on the classifying operation.

摘要： A chart includes: a substrate; a first skin reflection patch part that is formed on the substrate and that simulates reflection of near-infrared rays of a predetermined wavelength, in a skin of a living body of a first skin color; and a second skin reflection patch part that is formed on the substrate and that simulates reflection of the near-infrared rays of the predetermined wavelength, in the skin of the living body of a second skin color that is different from the first skin color. According to such a chart, it is possible to properly determine whether or not an imaging environment of an image is suitable for biometric authentication.

摘要： An illumination device and method are provided herein for calibrating individual LEDs in the illumination device to obtain a desired luminous flux and a desired chromaticity of the device over changes in drive current, temperature, and over time as the LEDs age. The calibration method may include subjecting the illumination device to a first ambient temperature, successively applying at least three different drive currents to a first LED to produce illumination at three or more different levels of brightness, obtaining a plurality of optical measurements from the illumination produced by the first LED at each of the at least three different drive currents, obtaining a plurality of electrical measurements from the photodetector and storing results of the obtaining steps within the illumination device to calibrate the first LED at the first ambient temperature. The plurality of optical measurements may generally include luminous flux and chromaticity, the plurality of electrical measurements may generally include induced photocurrents and forward voltages, and the calibration method steps may be repeated for each LED included within the illumination device and upon subjecting the illumination device to a second ambient temperature.

摘要： In the method for optical monitoring and/or determination of properties on samples, monochromatic electromagnetic radiation with a predetermined wavelength is sequentially directed from several radiation sources onto a sample influenced by an electronic evaluation unit. The respective intensity specific to the wavelength of the electromagnetic radiation scattered and/or reflected by the sample is detected by at least one detector and fed to the electronic evaluation unit for spectrally resolved evaluation in order to use it to monitor and/or determine properties of the respective sample.
