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.

Claims (44)

1. A imaging device, the imaging device comprising:

a first image sensor;

a second image sensor; and

at least one processor communicatively coupled to the first image sensor and the second image sensor, wherein the at least one 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 at least in part on operating distance associated with the imaging device from an object.

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

determine an operating distance of the imager device based at least in part on a position of the image of the projected aimer light in the first image and the second image.

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

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

12. A method for operating an imaging device, the method 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 at least in part on operating distance associated with the imaging device from an object.

13. The method of claim 12 , further comprising modifying the at least one of the first duty cycle or the second duty cycle based at least in part on historical data pertaining to tasks previously performed by an 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 at least in part 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 at least in part on a position of the image of the projected aimer light in the first image and the second image.

20. A method for operating an imaging device, the method comprising:

activating a first image sensor at a first duty cycle within a first time period;

in response to activation of the first image sensor, activating a first illuminator source;

activating a second image sensor at a second duty cycle within the first time period;

in response to activation of the second image sensor, activating a second illuminator source; and

modifying at least one of the first duty cycle or the second duty cycle based at least in part on operating distance associated with the imaging device from an object.
