IAC, the Fuji sensor is arranged so that all of the lower sensitivity pixels are Green in the Bayer CFA. Since there are twice as many Green pixels as Red *or* Blue pixels this tends to equalize the color sensitivities. According to their literature, this is done by making them smaller. This is going to reduce the thermal noise (constant) but not the image noise (variable). --- end of quote ---
All the gory details are here: http://en.wikipedia.org/wiki/Super_CCD There are low and high sensitivities of _every_ pixel. I was browsing around and found a sensor for us to consider (there are others on the same site): http://www.aptina.com/products/image_sensors/mt9p401i12stc/ I also realized we have a problem -- how are we going to use 35mm lenses? Unless we put some refractive optics in, either the sensors will cost a LOT of money (for APS-C or 35mm sensors) or only long focal length equivalents are possible. I would almost prefer going the fast prime 35-40mm equivalent on a cheap, high quality, rugged, FOSH camera. Of course, another option is to make it a Super16 camcorder... _______________________________________________ Open-hardware mailing list Open-hardware@duskglow.com http://lists.duskglow.com/mailman/listinfo/open-hardware
