Abstract: The present disclosure generally pertains to time-of-flight data generation circuitry, configured to: acquire a time-of-flight (ToF) data stream using a ToF camera; acquire a brightness change event data stream using an event-based vision sensor (EVS), camera; correlate the time-of-flight data stream with the brightness change event data stream in time with each other for generating at least one time-of-flight data frame; and generate the at least one time-of-flight data frame based on the correlation.

Abstract: The present disclosure generally pertains to time-of-flight demodulation circuitry configured to: determine a light event pattern with an event-based light detection element of a plurality of event-based light detection elements; and determine, for a demodulation element of a plurality of demodulation elements, a timing for a demodulation signal to be applied to the demodulation element based on the light event pattern, wherein the demodulation element is associated with the event-based light detection element.

Abstract: A method and system comprising one or more event-based vision sensors for monitoring an environment and one or more depth sensors monitoring the environment as well as potentially additional sensors to monitor the environment such as inertial measurement units and image sensors. The device as a processor assembly will then monitor the event-based vision sensor and the depth sensor and other sensors and determine whether to adapt a control schem, such as activate, the depth sensor to acquire depth information of the environment based on the response of the event-based vision sensor. This approach leverages advantages of event-based sensors to reduce the power consumption but still react quickly to such changes by continuously measuring intervals directly relating to the minimally admitted delays in the application for which depth measurements or inferred data are used.
