1. An apparatus comprising:
- a local component to issue a signal;
an infrared (IR) projector;
a request handler to;
detect a snapshot request to conduct a long range depth capture based on the signal from the local component; and
detect a preview request to conduct a short range depth capture;
a mode controller communicatively coupled to the IR projector and the request handler, the mode controller to;
activate the IR projector at a first power level for a first duration in response to the snapshot request, wherein the first power level is to be greater than a second power level corresponding to the short range depth capture and the first duration is to be less than a second duration corresponding to the short range depth capture; and
activate at least one IR projector at the second power level for the second duration in response to the preview request;
a three-dimensional (3D) sensor to detect a pattern of IR light; and
a pattern synchronizer to conduct a synchronization between a pattern of IR light output from the IR projector and the pattern of light detected by the 3D sensor.

Abstract
Systems, apparatuses and methods may provide for detecting a snapshot request to conduct a long range depth capture, wherein the snapshot request is associated with a short range depth capture. Additionally, an infrared (IR) projector may be activated at a first power level for a first duration in response to the snapshot request, wherein the first power level is greater than a second power level corresponding to the short range depth capture and the first duration is less than a second duration corresponding to the short range depth capture.
