The idea of a video camera Open Source you can intrigue. Really apertus has a small sensor but the project is licensed under the GPL allows anyone to come later and change the sensor by a bigger, better, for example. This means that there would be the 'known' patent issues.

Of course performance, reliability and confidence in the product are key elements to become a real actor in the market. And that apertus is a project born in 2006 and is part of Open Cinema movement.
