Background Megapixel race has resulted in an excess of pixels Other types of useful information that a camera can capture: Multispectral Polarization Images removed due to copyright restrictions. See references [4], [5]. High Dynamic Range [4,5] Images removed due to copyright restrictions. See references [1], [2], [3]. Images removed due to copyright restrictions. [1-3] ] See reference [6]. 2 [6] Can all of this be captured in a single image?
