Abstract

A data capture device includes: a display, a primary image sensor having a primary field of view centered on a primary optical axis; an auxiliary image sensor having an auxiliary field of view centered on an auxiliary optical axis, wherein the auxiliary field of view is larger than the primary field of view; a memory storing offset data defining an offset between the primary field of view and the auxiliary field of view; a data capture controller connected to the primary image sensor, the auxiliary image sensor and the memory; wherein the data capture controller is configured to: responsive to activation of an aiming mode, control the auxiliary image sensor to capture a video stream; select, according to the offset data, a portion of the video stream corresponding to the primary field of view; and present the selected portion of the video stream on the display.

First claim

The invention claimed is:

1. A data capture device, comprising:
a housing;
a display supported by the housing;
a primary image sensor supported by the housing and having a primary field of view centered on a primary optical axis;
an auxiliary image sensor supported by the housing and having an auxiliary field of view centered on an auxiliary optical axis, wherein the auxiliary field of view is larger than the primary field of view;
a memory storing offset data defining an offset between the primary field of view and the auxiliary field of view;
a data capture controller connected to the primary image sensor, the auxiliary image sensor and the memory, wherein the data capture controller is configured to:
responsive to activation of an aiming mode, control the auxiliary image sensor to capture a video stream within the auxiliary field of view,
select, according to the offset data, a portion of the video stream corresponding to the primary field of view of the primary image sensor, and
present the selected portion of the video stream, based on the offset data, on the display.

2. The data capture device of claim 1 , wherein the data capture controller is further configured to present, with the selected portion of the video stream, a boundary indicating the primary field of view.

3. The data capture device of claim 1 , wherein the primary image sensor and the auxiliary image sensor are supported by the housing within an image sensor plane.

4. The data capture device of claim 3 , wherein the offset data defines a distance between the primary image sensor and the auxiliary image sensor within the image sensor plane.

5. The data capture device of claim 3 , wherein the offset data defines a plurality of distances within the image sensor plane, each of the plurality of distances corresponding to a range.

6. The data capture device of claim 1 , wherein the data capture controller is configured to present the selected portion of the video stream centered on the display.

7. A method in a data capture device, the method comprising:
storing offset data in a memory of the data capture device, the offset data defining an offset between a primary field of view of a primary image sensor and an auxiliary field of view of an auxiliary image sensor;
responsive to activation of an aiming mode, controlling the auxiliary image sensor to capture a video stream within the auxiliary field of view;
selecting, according to the offset data, a portion of the video stream corresponding to the primary field of view of the primary image sensor; and
presenting the selected portion of the video stream on a display of the data capture device.

8. The method of claim 7 , further comprising: presenting on the display, with the selected portion of the video stream, a boundary indicating the primary field of view.

9. The method of claim 7 , further comprising:
determining that the data capture operation has been initiated responsive to detecting activation of a primary input of the data capture device; and
activating the aiming mode responsive to activation of an auxiliary input of the data capture device.

10. The method of claim 7 , wherein the primary image sensor and the auxiliary image sensor are supported within an image sensor plane by a housing of the data capture device.

11. The method of claim 10 , wherein the offset data defines a distance between the primary image sensor and the auxiliary image sensor within the image sensor plane.

12. The method of claim 10 , wherein the offset data defines a plurality of distances within the image sensor plane, each of the plurality of distances corresponding to a range.

13. The method of claim 7 , wherein presenting the selected portion of the video stream comprises presenting the selected portion centered on the display.

14. A non-transitory computer-readable medium storing computer-readable instructions executable by a controller of a data capture device to cause the data capture device to:
store offset data in a memory of the data capture device, the offset data defining an offset between a primary field of view of a primary image sensor and an auxiliary field of view of an auxiliary image sensor;
responsive to activation of an aiming mode, control the auxiliary image sensor to capture a video stream within the auxiliary field of view;
select, according to the offset data, a portion of the video stream corresponding to the primary field of view; and
present the selected portion of the video stream on a display of the data capture device, based on the offset data between the auxiliary field of view and the primary field of view.
