Abstract

The various embodiments illustrated herein disclose a method for operating an imaging device. the method includes activating a first image sensor at a first duty cycle within a first time period. The method further includes activating a second image sensor at a second duty cycle within the first time period. Additionally, the method includes modifying at least one of the first duty cycle or the second duty cycle based on at least a workflow associated an operator of the imaging device.

First claim

What is claimed is:

1. A imaging device, the imaging device comprising:
a first image sensor;
a second image sensor; and
a processor communicatively coupled to the first image sensor and the second image sensor, wherein the processor is configured to:
activate the first image sensor at a first duty cycle within a first time period;
activate the second image sensor at a second duty cycle within the first time period; and
modify at least one of the first duty cycle or the second duty cycle based on at least a workflow associated with an operator of the imaging device.

2. The imaging device of claim 1 , wherein the processor is further configured to modify the at least one of the first duty cycle or the second duty cycle based on historical data pertaining to tasks previously performed by the operator operating the imaging device.

3. The imaging device of claim 1 , wherein the first image sensor is configured to capture a first set of images within the first time period, wherein the second image sensor is configured to capture a second set of images within the first time period.

4. The imaging device of claim 3 , wherein the processor is further configured to:
determine a first quality score for a first image in the first set of images;
determine a second quality score for a second image in the second set of images; and
compare the first quality score with the second quality score to determine whether the first image has a better quality than the second image.

5. The imaging device of claim 4 , wherein the processor is configured to increase the second duty cycle, in response to determining that the second quality score is greater than the first quality score, and wherein the processor is configured to increase the first duty cycle, in response to determining that the first quality score is greater than the second quality score.

6. The imaging device of claim 4 , wherein a quality score of an image is determined based on a measure of image sharpness, a measure of image brightness, and a presence of a machine readable code in an image.

7. The imaging device of claim 1 further comprising an aimer LED that is communicatively coupled to the processor, wherein the processor is configured to activate the aimer LED to project aimer light, wherein the aimer LED is activated during respective activation of the first image sensor and the second image sensor such that at least one first image of a first set of images and at least one second image of a second set of images includes an image of the projected aimer light.

8. The imaging device of claim 7 , wherein the processor is configured to:
determine an operating distance of the imager device based on a position of the image of the projected aimer light in the first image and the second image; and
modify the at least one of the first duty cycle and the second duty cycle based on the operating distance.

9. The imaging device of claim 1 further comprising a depth sensor communicatively coupled to the processor, wherein the processor is configured to determine an operating distance of the imager device based on a depth signal received from the depth sensor, wherein the processor is configured to modify the at least one of the first duty cycle and the second duty cycle based on the operating distance.

10. The imaging device of claim 1 further comprising one or more inertial sensors communicatively coupled to the processor, wherein the processor is configured to determine an orientation of the imaging device based on an orientation signal received from the one or more inertial sensors, wherein the processor is configured to modify the at least one of the first duty cycle and the second duty cycle based on the orientation of the imaging device.

11. The imaging device of claim 1 , wherein to modify at least one of the first duty cycle or the second duty cycle based on at least a workflow associated with the operator of the imaging device, the apparatus is configured to:
receive at least one user input from the operator; and
modify the first duty cycle or the second duty cycle to a predetermined value determined based on the at least one user input.

12. A method for operating an imaging device comprising:
activating a first image sensor at a first duty cycle within a first time period;
activating a second image sensor at a second duty cycle within the first time period; and
modifying at least one of the first duty cycle or the second duty cycle based on at least a workflow associated with an operator of the imaging device.

13. The method of claim 12 further comprising modifying the at least one of the first duty cycle or the second duty cycle based on historical data pertaining to tasks previously performed by the operator operating the imaging device.

14. The method of claim 12 , wherein the first image sensor is configured to capture a first set of images within the first time period, wherein the second image sensor is configured to capture a second set of images within the first time period.

15. The method of claim 14 further comprising:
determining a first quality score for a first image in the first set of images;
determining a second quality score for a second image in the second set of images; and
comparing the first quality score with the second quality score to determine whether the first image has a better quality than the second image.

16. The method of claim 15 further comprising increasing the second duty cycle, in response to determining that the second quality score is greater than the first quality score, and increasing the first duty cycle, in response to determining that the first quality score is greater than the second quality score.

17. The method of claim 15 , wherein a quality score of an image is determined based on a measure of image sharpness, a measure of image brightness, and a presence of a machine readable code in an image.

18. The method of claim 12 further comprising activating an aimer LED to project aimer light during respective activation of the first image sensor and the second image sensor such that at least one first image of a first set of images and at least one second image of a second set of images includes an image of the projected aimer light.

19. The method of claim 18 further comprising:
determining an operating distance of the imager device based on a position of the image of the projected aimer light in the first image and the second image; and
modifying the at least one of the first duty cycle and the second duty cycle based on the operating distance.

20. A method for operating an imaging device comprising:
activating a first image sensor at a first duty cycle within a first time period;
activating a second image sensor at a second duty cycle within the first time period; and
modifying at least one of the first duty cycle or the second duty cycle based on at least a historical data associated with one or more tasks previously performed by an operator of the imaging device.
