1. An apparatus, comprising:
- a sensor module arranged to capture a low-resolution image of a predetermined area in a first operating mode and a higher-resolution, three-dimensional image of the predetermined area in a second operating mode;
a control module arranged to determine a difference between the low-resolution image or the higher-resolution image and a previously captured image of the predetermined area, and to determine an operating mode of the apparatus based on whether the difference indicates object movement within the predetermined area within a preset time duration.

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.

11. A system, comprising:
-
a sensor module comprised of photosensitive pixels arranged to capture a low-resolution image of a predetermined area in a standby mode and a higher-resolution, three-dimensional image of the predetermined area in an active mode; an illumination module arranged to emit light radiation based on an operating mode of the system; a modulation component arranged to modulate one or more photosensitive pixels of the sensor module and/or the light radiation based on the operating mode of the system; a control module arranged to determine a difference between the low-resolution image or the higher-resolution 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. - View Dependent Claims (12, 13, 14, 15, 16)

17. A method, comprising:
-
capturing a low-resolution image of a predetermined area with a three-dimensional imager in a first operating mode; capturing a higher-resolution, three-dimensional image of the predetermined area with the three-dimensional imager in a second operating mode; determining a difference between the low-resolution image or the higher-resolution 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; and operating the three-dimensional imager in the second operating mode when the difference indicates an object movement within the predetermined area. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24)

25. A three-dimensional imaging device, comprising:
-
a sensor module arranged to use time-of-flight principles to capture a two-dimensional and/or gray-scale image of a predetermined area in a first operating mode and a high-resolution, three-dimensional image of the predetermined area in a second operating mode; a control module arranged to determine a difference between the two-dimensional and/or gray-scale image or the high-resolution image and a previously captured image of the predetermined area, and to set the apparatus in the first operating mode when the difference indicates no object movement within the predetermined area within a preset time duration and to set the apparatus in the second operating mode when the difference indicates an object movement within the predetermined area.
