Abstract
A device includes a lens assembly to focus an image or to optically zoom, a sensor array to capture an image; a memory to store instructions; and a processor to execute the instructions. The processor may execute the instructions to: cause the sensor array to capture an image; determining a field of view in the captured image; obtain parameter values based on sensor measurements associated with the captured image; obtain a digital zoom profile and an optical zoom profile based on the parameter values, the captured image, and the field of view; and jointly apply the digital zoom profile and the optical zoom profile to set the camera to the received zoom request for the field of view.
