So, i'm trying to understand how 3 chip (cmos) camcorders operate. In fact, I understand how they operate - use a prism to split the light in to red, green, and blue, and therefore each sensor processes its respective colour separately
What, however, I would like to know, is whether a 3 chip cmos camcorder's sensor (i'm referring to the panasonic 900/ac90) surface area is the equivalent of adding the size of each sensor together (1/4.1in + 1/4.1in +1/4.1in)
From my understanding, when the light gets split, only 25% of the sensor gets used for the red and blue, and 50% for the green. Therefore total area would only be 1/4.1in? This is what I don't understand at the moment
I guess you have to factor in that it isn't using a bayer array pattern, so each pixel is getting the full light, not just a third of it like single cmos designs - so in that respect, the light gathering can be superior
Hope i'm making sense!
