Better fabrication process = better sensors = better images, photodiodes need to be made more identical to all the others on the same sensor, the more identical they are, the less noise they produce, as they'll produce more identical results, smaller photodiodes need to be even more indentical to maintain same noise levels of larger sensors, which is harder to do, as CPU tech increases and uses smaller fabrication processes, so will CMOS sensors, they can be smaller, or higher resolution or both (ie: smaller photodiodes), CMOS is the same process used for CPUs. http://en.wikipedia.org/wiki/CMOS http://en.wikipedia.org/wiki/Active_pixel_sensor
Now that we've thrown 'em off the trail, use the form below to get in touch with the people at Engadget. Please fill in all of the required fields because they're required.
No sorry thats not the physics at all.
