But, what is purpose of twice the vertical resolution (2x1080 px = 2160 px)? Here I found that:"...It was one normal row of photosites filtered for each color and one row ND'd to capture bright information per color".
Very logical answer,but is it truth!?
Today at presentation of Sony SRW-9000PL I asked about that and presenter told me oppositely explanation...
He said that no one ND was used over half of CCD's array.His theory is based on Gain function..."...It was one normal row of photosites filtered for each color and one row is amplified to capture information at low light (per color)". Amplification is made by Gain of +3dB...half array is read by 0 dB gain...second half is read by gain value of +3dB.
New theory sounds like a ALEXA readout mechanism...
There are two opposite explanations...what is the real story behind Sony's stripped CCD!?
