Abstract
Representative implementations of devices and techniques provide adaptable settings for imaging devices and systems. Operating modes may be defined based on whether movement is detected within a predetermined area. One or more parameters of illumination or modulation may be dynamically adjusted based on the present operating mode.
Claims24
An apparatus, comprising:
- a sensor configured to capture a two-dimensional image of an area in a first operating mode and a three-dimensional image of the area in a second operating mode;
- an illuminator configured to illuminate at least a portion of the area;
- and
- a controller configured to:
- determine a difference between the two-dimensional image or the three-dimensional image and a previously captured image of the area,
- determine an operating mode of the apparatus based on whether the difference indicates object movement within the area,
- activate or deactivate the illuminator based on the determined operating mode, and
- set the apparatus in the first operating mode when the difference indicates no object movement within the area.
5 more elements
A system, comprising:
- a sensor comprised of photosensitive pixels configured to capture a two-dimensional image of a predetermined area in a standby mode and a three-dimensional image of the predetermined area in an active mode;
- an illuminator configured to emit light radiation based on an operating mode of the system;
- a modulator configured to modulate one or more photosensitive pixels of the sensor and/or the light radiation based on the operating mode of the system;
- and
- a controller configured to determine a difference between the two-dimensional image or the three-dimensional image and a previously captured image of the predetermined area, and to determine the operating mode of the system based on whether the difference indicates object movement within the predetermined area within a preset time duration.

A method, comprising:
- capturing a two-dimensional image of a predetermined area with a three-dimensional imager in a first operating mode;
- capturing a three-dimensional image of the predetermined area with the three-dimensional imager in a second operating mode;
- determining a difference between the two-dimensional image or the three-dimensional image and a previously captured image of the predetermined area;
- operating the three-dimensional imager in the first operating mode when the difference indicates no object movement within the predetermined area within a preset time duration;
- operating the three-dimensional imager in the second operating mode when the difference indicates an object movement within the predetermined area;
- and
- illuminating at least a portion of the predetermined area based on which of the first and the second operating modes the three-dimensional imager is operating.
4 more elements
A three-dimensional imaging device, comprising:
- a sensor configured to use time-of-flight principles to capture a two-dimensional image of an area in a first operating mode and a three-dimensional image of the area in a second operating mode;
- an illuminator configured to illuminate at least a portion of the area;
- and
- a controller is configured to:
- determine a difference between the two-dimensional image or the three-dimensional image and a previously captured image of the area,
- set the device in the first operating mode when the difference indicates no object movement within the area within a preset time duration and to set the device in the second operating mode when the difference indicates an object movement within the area, and
- activate or deactivate the illuminator based on which of the first and the second operating modes the device is set to operate in.
