Merging video with time-decimated high-resolution imagery to form high-resolution video frames

摘要

Apparatus and methods for generating a shutter-time compensated high spatial resolution (HR) image output by enhancing lower spatial resolution (LR) video images with information obtained from higher spatial resolution still images which are temporally decimated. Super-resolved images and LR SAD information is generated from the LR images and used for directing the extracting of information from the temporally decimated HR images to enhance the spatial resolution of the LR images in a blending process. By way of example blending can comprise: motion estimation, motion compensation of a temporally displaced HR still images and a super-resolved (SR) image input, transformation (e.g., DCT), generating motion error output, blending motion compensated images in response to LR motion error information; inverse-transformation into a shutter-time compensated HR video image output. Accordingly, a more cost effective solution is taught for obtaining a desired shutter time and video resolution.
