Abstract
Representative implementations of devices and techniques provide adaptive distance estimation for imaging devices and systems. Distance estimation may be based on phase delays in reflected light. Reference phases used to determine phase delay values may be changed for subsequent frame events. Multiple frame events may be selected for some distance calculations based on whether object movement is detected within a predetermined area.
