1. A method for camera control to acquire an image, comprising:
acquiring a stream of image frames by an image sensor comprising at least one frame;
acquiring a target frame by the image sensor;
determining scene information of the target frame;
selecting at least one reference frame from the stream of image frames by identifying the scene information of the target frame in the reference frame;
determining at least one acquisition parameter of the reference frame; and
determining a final image from the target frame by correcting at least one corresponding acquisition parameter of the target frame using the at least one acquisition parameter of the reference frame,
wherein the scene information comprises simultaneous localization and mapping (SLAM) data for the image frame of the stream of image frames and the target frame.
