Video acquisition with processing based on ancillary data

摘要

Systems and techniques for processing sequences of video images involve receiving, on a computer, data corresponding to a sequence of video images detected by an image sensor. The received data is processed using a graphics processor to adjust one or more visual characteristics of the video images corresponding to the received data. The received data can include video data defining pixel values and ancillary data relating to settings on the image sensor. The video data can be processed in accordance with ancillary data to adjust the visual characteristics, which can include filtering the images, blending images, and/or other processing operations.

1. A method comprising:
receiving captured video data from an image sensor, the video data defining a sequence of frames including a first frame and a second frame detected after the first frame, with each frame including pixel data for a plurality of pixels; estimating a visual noise level in at least the second frame; detecting a degree of motion between the first frame and the second frame; and filtering the second frame by modifying pixel data for the second frame based on pixel data from the first frame using a filtering parameter that defines a degree of the modification, wherein the filtering parameter is determined based on the estimated visual noise level for the second frame and the degree of motion between the first frame and the second frame.
