128x128 1" round or 0.7"x0.7" B/W. These camera's are based on the Mitsubishi CMOS image sensor chip. The chip itself is quite intelligent with the ability to a 3x3 filter on the image in real time. Takes a processor to set up and run it. See also:
Sir Douglas says:
For people with Large Screen TV hooked up to their computer that want a Free GREEN SCREEN:All they have to do is make a movie of a GREEN background or change their DESKTOP to be NO ICONS and GREEN in color and view it on their large screen TV. Then they can stand in between the TV's Green Screen and their movie camera and make awesome Movies.
The problem with Green screens is that you need a lot of light to avoid shadows which produce different shades of GREENS; However, if you use a Large Screen DLP the back-lit background will produce NO variation of GREENS.
Sure it is only good for people that don't have money that want to produce YouTube videos... but still it does work very well.
Has anybody ever tried:
The point here is that the two motor driven mirrors can spin very quickly with little current draw while generating an (almost) raster scan pattern that is corrected for by software. You can reduce the need for mapping by not starting the scans until the beam is a bit away from the edge.
Andy Howard says:
A technique similar to this was used in some of the very earliest electro-mechanical TV experiments. Spinning drums with mirrors attached all around to form a regular polygon were used to give scanning with near-instant flyback.I've recently seen a similar-looking arrangement used with a lightshow laser to project computer-generated video snippets.
