Very high resolution image acquisition through image reconstructionfrom lower resolution images taken with multiple cameras

摘要

Some research institutes are elaborating plans to develop veryhigh definition (VHD) visual media beyond the HDTV. Although a CCDcamera with two million pixels has been developed for HDTV, the spatialresolution should be increased further to acquire VHD images. Reducingthe pixel size is the most straightforward way to increase the spatialresolution, which makes a CCD imager much more sensitive to shot noise.To keep shot noise invisible on a monitor, there needs to be alimitation in the pixel size reduction. The current CCD technology hasalmost reached this limit. Therefore, a new approach is required toenhance the spatial resolution further beyond this limit. The authorspresent a new method for acquiring VHD images by processing andintegrating multiple images taken simultaneously with different cameras
