Abstract
A time-of-flight (ToF) camera is configured to operate in a manner that reduces power consumption of the ToF camera. For a key frame, a key-frame depth image is generated based on a plurality of sets of key-frame IR images. Each set of key-frame IR images is acquired using a different modulation frequency of active IR light. For a P-frame after the key frame, a P-frame depth image is generated based on a set of P-frame IR images acquired using a single modulation frequency of active IR light.
