    Abstract: An electronic device such as a cellular telephone or other device may have a housing with front and rear faces joined by a sidewall. A display may be mounted on the front face. The electronic device may include multiple ambient light sensors such as a front ambient light sensor on the front face and one or more supplemental ambient light sensors on the rear face and/or on the sidewall. The front ambient light sensor gathers a front ambient light intensity measurement and the supplemental ambient light sensor gathers a supplemental ambient light intensity measurement. During operation, control circuitry in the electronic device adjusts the display brightness based on data from the ambient light sensors. The control circuitry may implement power saving restrictions that limit when the supplemental ambient light intensity measurement is taken into account and/or that impose a brightness cap on the display brightness.

    Abstract: An electronic device such as a desktop computer or other device may have an electronic device housing with front and rear faces. A display may be mounted on the front face. The electronic device may include multiple ambient light sensors such as a front color ambient light sensor on the front face and a rear color ambient light sensor on the rear face. The front ambient light sensor gathers a front ambient light intensity measurement and a front ambient light color measurement. The rear ambient light sensor gathers a rear ambient light intensity measurement and a rear ambient light color measurement. During operation, control circuitry in the electronic device takes action based on data from the ambient light sensors. The control circuitry may adjust a white point of the display using a combined color value that is produced using a combining function.

    Abstract: An electronic device may have a main display and an ancillary display that forms a dynamic function row. The device may also have a backlit keyboard with glyphs. The keyboard may have light-emitting diodes that emit backlight illumination. The backlight illumination has a backlight illumination color and intensity. A color ambient light sensor may measure ambient light color and intensity. Control circuitry in the laptop computer may make white point adjustments to the main and ancillary displays. White point adjustments may be made based on factors such as the backlight illumination intensity, information on the nominal white point of a display (which may be comparable to the color of the backlight illumination), information on the ambient light color and intensity, and a white point adaptation scaling factor.

    Abstract: Various embodiments include a light source module with one or more light emitters and one or more light sensors that share an aperture via which light passes. One of the light sensors may measure illuminance received through the aperture (not illuminance from the light emitters) and send a signal indicating a measurement of the illuminance. The light source module may be integrated into a portable computing device having a controller. The controller may include logic to perform one or more device operations based on the measurement of illuminance, such as, but not limited to, controlling a device display brightness and/or controlling an auto exposure feature of the device camera. Calibration parameters for interpreting the signal may be determined via a calibration process.

    Abstract: An electronic device may include a display for displaying image content to a user and dynamic image stabilization circuitry for dynamically compensating the image content if the device is moving unpredictably to help keep the image content aligned with the user's gaze. The electronic device may include sensors for detecting the displacement of the device. The dynamic image stabilization circuitry may include a usage scenario detection circuit and a content displacement compensation calculation circuit. The usage scenario detection circuit receives data from the sensors and infers a usage scenario based on the sensor data. The content displacement compensation calculation circuit uses the inferred usage scenario to compute a displacement amount by which to adjust image content. When motion stops, the image content may gradually drift back to the center of the display.
