  • Patent number: 12163839
    Abstract: The present disclosure describes a method and apparatus that can be used to determine various characteristics of ambient light when an ambient light sensor is located behind a display screen. The strategy of the disclosure relies, at least in part, on spectral decomposition of ambient light measurements into components (e.g., red, green, and blue components of an Organic Light Emitting Diode (“OLED”) display screen and ambient light). Following the spectral decomposition technique, statistical analysis are performed on the measurement data to remove the OLED light components from the measurement. This technique enables determinations such as ambient lux and correlated color temperature independent of the content displayed on the screen.

  • Patent number: 11774563
    Abstract: A method of using an optical TOF module to determine distance to an object. The method includes acquiring signals in the TOF module indicative of distance to the object, using a first algorithm to provide an output indicative of the distance to the object based on the acquired signals, using at least one second different algorithm to provide an output indicative of the distance to the object based on the acquired signals, and combining the outputs of the first and at least one second algorithms to obtain an improved estimate of the distance to the object. In some implementations, each of the first and at least one second algorithms further provides an output representing a respective confidence level indicative of how accurately distance to the object has been extracted by the particular algorithm.

  • Patent number: 11588977
    Abstract: The present disclosure describes a method and apparatus that can be used to adjust for distorted ambient light readings caused by the ambient light sensor being located behind the display screen. The strategy of the disclosure relies, at least in part, on spectral decomposition of ambient light measurements into independent sources (e.g., red, green, and blue display components of an Organic Light Emitting Diode (“OLED”) display screen and ambient light). Following the spectral decomposition technique, a more accurate ambient light measurement can be obtained in some instances. This technique enables determinations such as ambient lux and correlated color temperature independent of the content displayed on the screen.

  • Publication number: 20230052228
    Abstract: A method of measuring a distance using a time of flight sensor comprising a substantially transparent cover covering a light emitter and one or more photodetectors. The method comprises emitting a series of pulses of light from the light emitter; and using the one or more photodetectors to obtain a distribution of times at which at least one photodetector of the one or more photodetectors detected photons after each emission of the series of pulses of light. If the distribution of times comprises only a single peak, the method further comprises analysing the single peak to determine if the single peak includes counts of photons reflected from a target. If the single peak includes counts of photons reflected from a target, the method further comprises measuring the separation between a reference time and a point of the single peak.

  • Patent number: 11580901
    Abstract: Techniques are described for portable computing devices and other apparatus that include an ambient light sensor. The techniques can be particularly advantageous for situations in which the ambient light sensor is disposed behind a display screen of a host device such that ambient light detected by the sensor passes through the light emitting display before being detected by the sensor.

  • Publication number: 20220196812
    Abstract: Time of Flight Sensor A method of measuring optical crosstalk in a time of flight sensor, which comprises a substantially transparent cover covering a light emitter and one or more photodetectors. The method comprises emitting a series of pulses of light from the light emitter; and using the one or more photodetectors to obtain a distribution of times at which at least one photodetector of the one or more photodetectors detected photons after each emission of the series of pulses of light. The method further comprises recording one or more parameters of the earliest peak if the distribution comprises two or more separate peaks.

  • Publication number: 20210405158
    Abstract: Techniques for determining dynamically the intensity of the reflection from a transmissive cover and neutralizing it so as to improve the accuracy of depth measurements. Depth measurements of light modulation at multiple frequencies—which also can be used for depth disambiguation—are obtained and used to decouple the information to estimate the intensity of the signal reflected by the transmissive cover itself or a smudge on the transmissive cover, and the intensity of the signal reflected by the target object.

  • Publication number: 20210341609
    Abstract: Modulated light is generated using a light source of a sensor module. Using a photodetector of the sensor module, an intensity of modulated light reflected from an object towards the photo detector is measured over a period of time. An electronic control device bins the measured intensity of the reflected modulated light according to a plurality of temporal bins, determines a first temporal bin having the greatest intensity among the plurality of temporal bins, and estimates a distance between the sensor module and the object based on a first temporal bin, and one or more additional temporal bins of the plurality of temporal bins.
