    Abstract: A color tone quantification device for a glossy color, in which the correlation with the color tone of the glossy color visually perceived by humans is further enhanced, is provided. The device comprises a coefficient calculation unit that calculates a coefficient calculated in consideration of a spatial distribution which is to be used to correct the chromaticity measured by a method including a specular reflection component obtained by measuring the reflection light obtained by reflection of measurement light to an area of an object; a chromaticity calculation unit that calculates an effective chromaticity obtained by weighting the chromaticity measured by the method including the specular reflection component with the coefficient calculated by the coefficient calculation unit; and an output unit that outputs the effective chromaticity as a stimulus value representing a glossy color of the area in a color space.

    Abstract: In an example method, one or more processing devices receive encoded image data, and cause visual content to be presented on a display device according to the encoded image data. Further, the one or more processing devices receive measurement data regarding the visual content presented on the display device, and determine, based on the measurement data, one or more first perceptual quantizer (PQ) codes corresponding to the visual content presented on the display device. Further, the one or more processing devices determine, based on the encoded image data, one or more second PQ codes, and determine one or more metrics indicative of a performance characteristic the display device based on the first PQ codes and the second PQ codes. The one or more processing devices store a data item including the one or more metrics.

    Abstract: A sensor package includes a semiconductor sensor chip having multiple light sensitive regions each of which defines a respective light sensitive channel. An optical filter structure is disposed over the sensor chip and includes filters defining respective spectral functions for different ones of the light sensitive channels. In particular, the optical filter structure includes at least three optical filters defining spectral functions for tristimulus detection by a first subset of the light sensitive channels, and at least one additional optical filter defining a spectral function for spectral detection by a second subset of the light sensitive channels encompassing a wavelength range that differs from that of the first subset of light sensitive channels.

    Abstract: A color-calibration system is provided, which includes a host, a reference display apparatus, and a display apparatus. The host calculates peak-intensity change rates relative to different gain values for blue, green, and red colors using a first spectrum and second spectrum of a first display panel of the reference display apparatus respectively in a first display mode and a second display mode. The host calculates peak-intensity ratios for blue, green, and red colors using the first spectrum and a third spectrum of the first display panel in a predetermined color-temperature display mode. The host calculates blue/green/red gains of a second display panel of the display apparatus using a fourth spectrum of the second display panel in the first display mode, the peak-intensity change rates, and peak-intensity ratios, so that the first display panel and the second display panel display a consistent color in the same predetermined color-temperature display mode.

    Abstract: System that enables urine testing in a home environment. A user may apply a urine sample to a card containing multiple tests, and capture an image of the card using a phone; an analysis system executing on the phone or in the cloud may analyze the image and determine test results. The test card and analysis system may compensate for variability in lighting conditions and time of exposure to the urine sample, which are difficult to control in a home environment. The test card may contain fiducial markers of known colors; the analysis system may adjust colors in the captured image based on appearance of these markers. Color adjustments may also compensate for nonuniform lighting across the card. The card may also contain time indicators that change appearance over time after urine is applied, and the analysis system may use these indicators to calculate the time of exposure.
