It's a new kind of image sensor, Progressive Scan CCD, that makes Optura Pi able to bring such clarity to fast moving subjects and that provides the versatility to create print-from-video with digital photo resolution.
A fleeing Bigfoot, sheets of water tumbling over Niagara Falls, a linebacker careening towards the goal - they all come through clear because you get both speed and clarity with Progressive Scan CCD. The same feature makes it possible to snatch crisp stills at 30 shots per second using Optura Pi's Digital Motor Drive.
Compare it to Interlace methods, which shoot half an image at a time and combine the two to produce a single frame. The lapse of time between the halves blurs motion, and produces a disturbing image flicker when paused. Progressive Scan CCD is the superior, next-generation technology.
