Publication number: 20200294468Abstract: 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.Type: ApplicationFiled: March 13, 2019Publication date: September 17, 2020Inventors: Po-Chieh Hung, Prashanth S.

Patent number: 10670786Abstract: 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.Type: GrantFiled: April 13, 2018Date of Patent: June 2, 2020Assignee: Apple Inc.Inventors: Dong Zheng, Ove Lyngnes, Prashanth S.

Patent number: 10614752Abstract: 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.Type: GrantFiled: September 27, 2018Date of Patent: April 7, 2020Assignee: Apple Inc.Inventors: Christopher M.

Publication number: 20200022239Abstract: 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.Type: ApplicationFiled: July 12, 2018Publication date: January 16, 2020Inventors: Po-Chieh Hung, Serhan O.

Patent number: 10426402Abstract: 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.Type: GrantFiled: December 20, 2013Date of Patent: October 1, 2019Assignee: APPLE INC.Inventors: Justin Shi, Brian R.
