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.
