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: 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.
