Abstract: A method includes: a processing apparatus receives collected information from a detector. The collected information includes at least one of the following: reflected-light information of a user, thermal radiation information of the user, or image information of the user. The processing apparatus determines, based on the collected information, a first optical receiver unit that is in the detector and that collects ROI information of the user. The processing apparatus determines, based on a correspondence between optical receiver units and time units, a first time unit corresponding to the first optical receiver unit. The processing apparatus increases an irradiation power of a light source in the first time unit.

Abstract: The technology of this application relates to a signal processing apparatus having functions of communication and positioning and sensing, so that complexity of a photoelectric detector array is reduced. The apparatus includes N photoelectric detector unit subarrays and M output ports respectively connected to the N photoelectric detector unit subarrays, where at least two of the N photoelectric detector unit subarrays are different, a quantity of photoelectric detector units included in at least one of the N photoelectric detector unit subarrays is greater than or equal to 2, N is an integer greater than or equal to 2, and M is an integer less than or equal to N. A photoelectric detector unit in the N photoelectric detector unit subarrays is configured to perform photoelectric conversion on an optical signal, to obtain a first electrical signal, and the M output ports are configured to output the first electrical signal.
