CAMERA PARAMETER-ASSISTED VIDEO ENCODING
First Claim
1. A method comprising:
- obtaining one or more video capture parameters associated with captured video frames;
detecting a scene change in the captured video frames based on the one or more video capture parameters; and
encoding the captured video frames based on the detected scene change.

Abstract
This disclosure describes techniques for improving functionalities of a back-end device, e.g., a video encoder, using parameters detected by a front-end device, e.g., a video camera. The techniques may involve detecting a scene change in a captured frame, based on one or more parameters of auto exposure (AE), auto white balance (AWB), and auto focus (AF) functions. If a scene change is detected in a captured frame, a video processing device, which may be a stand-alone device, or may be integrated into one of the front-end or back-end devices, provides an indication of the scene change. The video encoder interprets the signal as a trigger to encode the frame indicated as the frame where a scene change occurred as a reference I frame.
