Abstract: A time of flight-based system is operable for ambient light measurements. A method of operation includes detecting, in at least one active demodulation detection pixel, a first particular wavelength and generating amplitude data of the first particular wavelength; and detecting, in at least one spurious reflection detection pixel, a second particular wavelength and generating amplitude data of the second particular wavelength. In a computational device that stores spectrum data corresponding respectively to a plurality of different ambient light source types, an ambient lighting condition is determined based on the amplitude data of the first particular wavelength, the amplitude data of the second particular wavelength and the spectrum data of a particular one of the ambient light source types associated with the amplitude data of the first particular wavelength and the amplitude data of the second particular wavelength.

Abstract: The present disclosure describes intelligent illumination systems that use modulated light. For example, in one aspect, a method includes producing, by a light source, modulated illumination in a visible part of the spectrum, detecting three-dimensional image data based on at least a portion of the modulated light produced by the light source and reflected by a scene, and changing a characteristic of the modulated illumination based on the detected three-dimensional image data.

Abstract: An optoelectronic module includes a first light emitter operable to emit radiation at a first wavelength toward an object outside the module. The module also includes demodulation pixels operable to detect radiation of the first wavelength reflected from the object. One or more processors are operable to determine a distance to the object based on the radiation detected by the demodulation pixels. The module is further operable to perform a supplemental measurement other than distance.

Abstract: The present disclosure describes imaging techniques and devices having improved autofocus capabilities. The imaging techniques can include actively illuminating a scene and determining distances over the entire scene and so that a respective distance to each object or point in the scene can be determined. Thus, distances to all objects in a scene (within a particular range) at any given instant can be stored. A preview of the image can be displayed so as to allow a user to select a region of the scene of interest. In response to the user's selection, the imager's optical assembly can be adjusted automatically, for example, to a position that corresponds to optimal image capture of objects at the particular distance of the selected region of the scene.

Abstract: Imaging systems include multi-tap demodulation pixels for biometric measurements such as heart rate or blood oxygen level. Using multi-tap demodulation pixels can, in some cases, help facilitate the generation of differential signals to remove background noise and achieve a higher dynamic range for the biometric measurements.
