摘要： The ambient illuminance sensor system disclosed herein includes a light sensor to generate a series of ambient illuminance values from an area surrounding a computing device, a human presence sensor configured to detect presence of a human in vicinity of the computing device, and computer implemented instructions for determining ambient illuminance level (AIL) based on at least in part on the series of ambient illuminance values, determining presence of a human in vicinity of the light sensor, and based on at least in part on determining that the AIL is below a threshold and that a human is present, applying a hysteresis filter to process the series of ambient illuminance values.

摘要： The description relates to hinged devices, such as hinged computing devices. One example can receive content data relating to a pair of displays that are rotatable around a hinge axis and that include curved regions proximate to the hinge axis. The example can generate a frame rendering for the content data that progressively dims the curved regions of the displays with decreasing distance from hinge axis.

摘要： OLED display color output may vary substantially as a function of display temperature, which changes over time. Luminance of each of the pixels is defined by the current flowing therethrough, which is a function of the applied voltage and resistivity of the pixels. Temperature affects the resistivity of the pixels and thus the current flowing therethrough if voltage is held constant. The temperature response of red, green, and blue pixels differs, particularly at low applied voltage levels. As a result, the relative luminance of red, green, blue may vary with temperature changes, which may yield an undesirable overall color variance. The presently disclosed systems and methods dynamically adjust driving voltage to maintain color quality within a desired specification, while also reducing (or in some implementations, minimizing) power consumption of the OLED display.

摘要： The ambient illuminance and light geometry detection system includes a computing process including receiving a hinge angle between two displays of a foldable computing device, illuminance values from illuminance sensors of the displays, and screen activity of each of the displays of the foldable computing device, determining foldable computing device posture information based at least in part on the hinge angle and the screen activity of each of the displays, determining a user facing display of the foldable computing device based at least in part on the device posture information and the screen activity of the displays, assigning differential weights to an illuminance value received from an illuminance sensor of the user facing display compared to an illuminance value received from an illuminance sensor of the non-user facing display and generating an aggregate weighted average illuminance by applying the differential weights to the illuminance values of each of the displays.

摘要： Systems and methods for determining a colorimetric value from color measurements for multiple ambient color sensors which for each color measurement, in various approaches, select a lighting cluster similar to the color measurement and determine whether the color measurement is valid or invalid based on a calculated similarity between the color measurement and the selected lighting cluster, calculate a weight for the color measurement for combination with other color measurements based on the calculated similarity between the color measurement and its selected lighting cluster, determine whether the color measurement is valid or invalid based on perceptual color space distances for the color measurement for multiple reference light sources, and/or calculate a weight for the color measurement for combination with other color measurements based on the perceptual color space distances for multiple reference light sources.

摘要： A method for calibrating the color space on multiple displays in a computing system Includes determining a native color space (116, 118) for each of multiple displays (102, 104); dynamically selecting a target color space (122) to implement on each of the multiple displays based at least on part on the determined native color space of each one of the multiple displays; and instructing one of the multiple displays to map the associated native color space to the target color space.

摘要： Sensor calibration methods and systems can for providing accurate color values are disclosed. In one example, a method includes obtaining color measurements that indicate an amount of ambient light, as well as clustering the color measurements, and storing cluster parameters for the clustered color measurements. The method can further include automatic calculation of, for each cluster, generic transformation parameters for conversion of a color measurement to a calibrated color value. In another example, a method can include exposing a light sensor to a calibration ambient lighting, calculating sensor correction parameters for the light sensor, and storing the calculated parameters. As an additional example, an electronic device is adapted to determine calibrated color values with machine readable media storing cluster parameters, sensor correction parameters, and generic transform parameters used by the electronic device to calculate calibrated color values for ambient light sensor measurements.
