  • Patent number: 10847071
    Abstract: An electronic device may be provided with a display mounted in a housing. The display may have an array of pixels configured to display images. A display cover layer may overlap the array of pixels. A light sensor such as a color ambient light sensor may be mounted in the electronic device and may receive ambient light through an ambient light sensor window region in the display cover layer or other portion of the electronic device. A diffuser may be located between the display cover layer and the ambient light sensor. The diffuser may have a substrate such as a glass substrate. A lens layer may be supported by the substrate. The lens layer may be formed from a layer of ultraviolet-light-curable polymer in which an array of lenses has been formed. An infrared-light-blocking-and-visible-light-transmitting filter may be used to reduce infrared light reaching the ambient light sensor.

  • Patent number: 10838126
    Abstract: An electronic device may be provided with one or more light-sensing components such as a camera and a color ambient light sensor. Optical structures such as camera lenses or a light pipe may be used to convey light from a window in an electronic device to a light-sensing component. One or more infrared-light-blocking-and-visible-light transmitting light filters may be interposed between a light-receiving window in an electronic device and a light-sensing component. The light filters may include infrared-light-blocking glass substrates, silver or other infrared-light-blocking thin films, and/or thin-film interference filters formed from stacks of dielectric layers that serve as infrared light-blocking layers.

  • Patent number: 10788361
    Abstract: An electronic device may have a housing in which a display is mounted. The display may have an active area in which images are displayed by an array of pixels and an inactive area that is free of pixels. A color ambient light sensor may make color and luminance measurements on ambient light received through an ambient light sensor window in the inactive area of the display or elsewhere in the electronic device. The color ambient light sensor may have color ambient light sensor elements of different colors. The ambient light sensor elements may extend in a row along an edge of the display or may have other configurations. Analog-to-digital converter circuitry and switching circuitry may gather color ambient light sensor measurements and measurements indicative of whether or not the color ambient light sensor has been obscured by an external object from the light sensor elements.

    Abstract: A submersible electronic device such as a waterproof cellular telephone may be provided with an image sensor. The image sensor may capture images of underwater objects. Control circuitry in the submersible electronic device may adjust image contrast and color balance based on information from sensors and other information. The electronic device may have an ambient light sensor. The ambient light sensor may be a color ambient light sensor and may be used in measuring ambient lighting conditions above water and underwater. A depth sensor may be used in measuring the depth of the image sensor and other components of the electronic device underwater. Information on the depth of the image sensor, information on the distance of an underwater object to the image sensor, and angular orientation information for the electronic device and image sensor may be used in color balancing an image.

  • Publication number: 20200294468
    Abstract: An electronic device may have a display with an array of pixels configured to display images for a user. The electronic device may have an ambient light sensor for gathering ambient light information. Control circuitry in the electronic device may control the array of pixels while gathering measurements with the ambient light sensor. This allows the control circuitry to determine which portion of each ambient light sensor measurement is due to ambient light exposure and which portion of each ambient light sensor measurement is due to stray light from the array of pixels. The control circuitry can then remove the stray light contribution to the ambient light sensor measurements to produce corrected readings of ambient light levels. Display adjustments such as display brightness changes and color changes can be made using ambient light readings.

  • Patent number: 10670786
    Abstract: An electronic device may be provided with a color ambient light sensor. The color ambient light sensor may be used to measure an ambient light spectrum over a wavelength range of interest. Control circuitry in the electronic device can take actions based on the measured ambient light spectrum such as adjusting the brightness and color cast of content on a display. A display may have a display cover layer. The color ambient light sensor can be mounted under the display cover layer and may receive ambient light through the display cover layer. The color ambient light sensor may have a tunable wavelength filter such as an electrically adjustable Fabry-Perot resonator. A light collimator may be interposed between the display cover layer and the Fabry-Perot resonator to collimate ambient light that is passed to the Fabry-Perot resonator. A light detector measures the light passing through the Fabry-Perot resonator.

  • Patent number: 10614752
    Abstract: An electronic device may be provided with an ambient light sensor. The ambient light sensor may be a color ambient light sensor or a monochrome ambient light sensor. The electronic device may have a light-emitting component such as a display. During operation of the display, the display emits light. To reduce noise due to the emitted light while measuring ambient light, the ambient light sensor may have optical structures such as wave plates and polarizers. Theses optical structures may overlap light detectors. The optical structures may be configured to prevent ambient light from reaching a first of the light detectors while allowing ambient light to reach a second of the light detectors. The ambient light sensor may be configured to receive ambient light that has passed thorough an inactive area of a display or that has passed through a pixel array in an active area of a display.

  • Publication number: 20200022239
    Abstract: An electronic device may be operated in ambient light. The electronic device may have a color ambient light sensor that is configured to produce color ambient light sensor data based on the ambient light. The electronic device may also have a flicker sensor that has a faster response time than the color ambient light sensor and that is used in detecting dynamic changes in the ambient light. Control circuitry in the electronic device may analyze flicker sensor data to identify the number of light sources producing the ambient light. The control circuitry may apply a frequency transform to the flicker sensor data or make measurements with the flicker sensor in multiple directions. Based on this information, the control circuitry may identify the number of light sources and may use this information in retrieving an ambient light spectrum associated with the ambient light using the color ambient light sensor data.

  • Patent number: 10426402
    Abstract: A portable electronic device include one or more electrodes for calculating distances and rotational angles between the device and the user is disclosed. Based on the calculated distances and rotational angles, a physical activity of the user can be determined. Additionally, the calculated distances and rotational angles can be used for compensation of optical artifacts in one or more signals detected by the device. User movement or physical activity can introduce optical artifacts, which can lead to erroneous determination of the one or more characteristics. The calculated distances and rotational angles can be used to reduce or remove the optical artifacts, leading to a more accurate determination of the one or more characteristics of the user.
