Why not small FFT CCDs in P&S cameras?

Lucem · Feb 24, 2005

Wouldn't the smaller sensors like 1/1.8" and 2/3" benefit the most from the increased fill factor.

I know, I know, then we loose the live EVF, but I bet some pros and enthusiast will go for it for the combination of small form factor as well as superior image quality.

Any reasons.?

I think that all cameras could benefit from FFT sensors regardless of the size.

Basically is a differnt layout of the tranfer pipelines coming from the photodiodes, That unlike Interline Image Transfer CCDs use more efficiently the sensor area that captures light resulting in better performance due to larger photodiodes.

Olympus puts it much nicer here.

And if you are interested in more details Kodak made this nice Acrobat document here. Go to Page 22.

Hope is clear now.

This is another Olympus link...this is a more visual description of the FFT CCD.

I hope this really helps explain things. The FFT was one of the top 5 reasons I got the E1.

Microlenses pretty much eliminate any fill factor advantage, and the necessity of a mechanical shutter is a pointless added expense.

And here I was wondering what on earth a Fast Fourier Transform sensor was....
