Classification: CPC G  H | IPC G  H

Claim 12:
13. A system for processing a video stream, the system comprising:
an image sensor configured to capture frame data of a current frame of a video stream; and
a first processor coupled to the image sensor, the first processor being configured to—
obtain the frame data from the image sensor;
determine frame difference data based on a comparison of the frame data of the current frame and scene cache data for a previous frame of the video stream, the scene cache data being stored in a scene cache for the video stream;
determine, based on the frame difference data, regions of the video stream to be re-sampled at a higher resolution than the frame data;
obtain, from the image sensor, re-sampling data for the determined regions;
update the scene cache data based on the obtained frame data and the re-sampling data; and
provide the re-sampling data to a second processor to update an analysis scene cache for the video stream.
