Abstract:
Embodiments of the invention provide techniques for upsampling a video sequence for coding. According to the method, an estimate of camera motion may be obtained from motion sensor data. Video data may be analyzed to detect motion within frames output from a camera that is not induced by the camera motion. When non-camera motion falls within a predetermined operational limit, video upsampling processes may be engaged. In another embodiment, video upsampling may be performed by twice estimating image content for a hypothetical new a frame using two different sources as inputs. A determination may be made whether the two estimates of the frame match each other sufficiently well. If so, the two estimates may be merged to yield a final estimated frame and the new frame may be integrated into a stream of video data.
