Abstract

A controller controls a camera that produces a sequence of images and that has output coupled to a video encoder. The camera has an operating condition including a field of view and lighting, and one or more imaging parameters. The video encoder encodes images from the camera into codewords. The controller receives one or more encoding properties from the video encoder, and causes adjusting one or more of the imaging parameters based on at least one of the received encoding properties, such that the camera produces additional images of the sequence of images for the video encoder using the adjusted one or more imaging parameters.
