Abstract
Systems, apparatus and methods for triggering a depth sensor and/or limiting bandwidth and/or maintaining privacy are presented. By limiting use of a depth sensor to times when an optical image alone is insufficient, mobile device power is saved. Furthermore, by reducing a size of an optical image to only the portion of the image needed to detect an object, bandwidth is saved and privacy is maintained by not communicating unneeded or undesired information.
Claims20
A method in a mobile device for triggering a depth sensor, the method comprising:
- capturing an image with an image sensing device;
- sending at least some of the image to a server to search for an object within the image;
- receiving an indication indicating the object was not found in the image with sufficient certainty;
- enabling the depth sensor and capturing depth information;
- converting the depth information into a depth map;
- and
- sending at least some of the depth map to the server.
A mobile device for triggering a depth sensor, the mobile device comprising:
- an image sensing device to capture an image;
- a transmitter to send at least some of the image to a server to search for an object within the image;
- a receiver to receive an indication indicating the object was not found with sufficient certainty;
- the depth sensor to capture depth information;
- and
- a processor coupled to the image sensing device, the transmitter, the receiver and the depth sensor, wherein the processor is configured to:
- enable the depth sensor;
- convert the depth information into a depth map;
- and
- send at least some of the depth map to the server.
A mobile device for triggering a depth sensor, the mobile device comprising:
- means for capturing an image with an image sensing device;
- means for sending at least some of the image to a server to search for an object within the image;
- means for receiving an indication indicating the object was not found in the image with sufficient certainty;
- means for enabling the depth sensor and capturing depth information;
- means for converting the depth information into a depth map;
- and
- means for sending at least some of the depth map to the server.
A non-transient computer-readable storage medium, for a mobile device for triggering a depth sensor, including program code stored thereon, comprising program code for:
- capturing an image with an image sensing device;
- sending at least some of the image to a server to search for an object within the image;
- receiving an indication indicating the object was not found in the image with sufficient certainty;
- enabling the depth sensor and capturing depth information;
- converting the depth information into a depth map;
- and
- sending at least some of the depth map to the server.
