Abstract

Automatic exposure control for audio/video (A/V) recording and communication devices in accordance with various embodiments of the present disclosure are provided. In one embodiment, an A/V recording and communication device is provided, comprising: a camera configured to capture image data of a foreground object within a field of view of the camera; a communication module; and a processing module comprising: a processor; and a camera application that configures the processor to: detect motion within the field of view that includes an active image region; capture image data of the field of view; detect the foreground object in the active image region and determine an external lighting level associated with the foreground object; determine at least one exposure control gain setting based on the determined external lighting level; and apply the at least one exposure control gain setting to configure the camera to capture image data focused on the foreground object.

Claims (34)

1. An audio/video recording and communication device (A/V device), comprising:

a camera configured to capture image data of a foreground object within a field of view of the camera, wherein the field of view includes a multi-exposure image condition;

a communication module;

a processor operatively connected to the camera and to the communication module; and

a memory storing a camera application comprising instructions that, when executed by the processor, cause the A/V device to:

detect motion within the field of view of the camera, wherein the field of view includes an active image region corresponding to a location where the motion was detected;

capture image data of the field of view, including the active image region, using the camera;

detect the foreground object in the active image region of the field of view and determine an external lighting level associated with the foreground object in the active image region;

determine at least one exposure control gain setting based on the external lighting level associated with the foreground object; and

apply the at least one exposure control gain setting to configure the camera to capture image data focused on the foreground object.

2. The A/V device of claim 1 , further comprising a motion sensor configured to detect the motion within the field of view of the camera.

3. The A/V device of claim 1 , wherein the camera application comprises further instructions that, when executed by the processor, further cause the A/V device to detect the motion within the field of view of the camera using the camera.

4. The A/V device of claim 1 , wherein the camera application comprises further instructions that, when executed by the processor, further cause the A/V device to track the foreground object within the field of view using the camera.

5. The A/V device of claim 1 , wherein the camera application comprises further instructions that, when executed by the processor, further cause the A/V device to determine the external lighting level associated with the foreground object using the image data captured using the camera.

6. The A/V device of claim 1 , wherein the at least one exposure control gain setting includes an aperture setting.

7. The A/V device of claim 1 , wherein the at least one exposure control gain setting includes a shutter speed setting.

8. The A/V device of claim 1 , wherein the at least one exposure control gain setting includes an ISO (International Organization of Standardization) setting.

9. The A/V device of claim 1 , wherein the camera application comprises further instructions that, when executed by the processor, further cause the A/V device to determine the at least one exposure control gain setting by comparing the external lighting level associated with the foreground object to a predetermined range of external lighting levels.

10. The A/V device of claim 1 , wherein the image data focused on the foreground object includes at least one frame that includes the foreground object in a higher image quality than found in the image data captured using the camera before applying the at least one exposure control gain setting.

11. A method for an audio/video recording and communication device (A/V device) comprising a camera, a communication module, and a processing module operatively connected to the camera and to the communication module, the method comprising:

detecting motion within a field of view of the camera, wherein the field of view includes an active image region corresponding to a location where the motion was detected, and includes a multi-exposure image condition where the field of view includes a first portion having a first external lighting level and a second portion having a second external lighting level;

capturing image data of the field of view, including the active image region, using the camera;

detecting a foreground object in the active image region of the field of view and determining an external lighting level associated with the foreground object in the active image region;

determining at least one exposure control gain setting based on the external lighting level associated with the foreground object; and

applying the at least one exposure control gain setting to configure the camera to capture image data focused on the foreground object.

12. The method of claim 11 , wherein the A/V device further comprises a motion sensor configured to detect the motion within the field of view of the camera.

13. The method of claim 11 , further comprising detecting the motion within the field of view of the camera using the camera.

14. The method of claim 11 , further comprising tracking the foreground object within the field of view using the camera.

15. The method of claim 11 , further comprising determining the external lighting level associated with the foreground object using the image data captured using the camera.

16. The method of claim 11 , wherein the at least one exposure control gain setting includes an aperture setting.

17. The method of claim 11 , wherein the at least one exposure control gain setting includes a shutter speed setting.

18. The method of claim 11 , wherein the at least one exposure control gain setting includes an ISO (International Organization of Standardization) setting.

19. The method of claim 11 , further comprising determining the at least one exposure control gain setting by comparing the external lighting level associated with the foreground object to a predetermined range of external lighting levels.

20. The method of claim 11 , wherein the image data focused on the foreground object includes at least one frame that includes the foreground object in a higher image quality than found in the image data captured using the camera before applying at least one auto-exposure setting.
