(FT5) new Panasonic 2.2/3-inch CMOS Image Sensor Based on Dual Resolution and Exposure Technique!
ISSCC published the Advance 2010 Program which contains some interesting new sensor developments news:
There is a description of the new Panasonic sensor with “2.2/3-Inch 4K2K dual resolution and exposure CMOS imager uses motion information to improve the sensitivity by 4 times in comparison to a conventional sensor. The green pixels are read out once every four frames for high sensitivity. Both the red and blue pixels are read out each frame, binned for 2×2 and used for motion compensation.”
Sounds like an amazing tecnology! I expect the new sensor to find his way in future Panasonic videocameras.

First off, what’s with this baloney ’2.2/3″‘ sensor size? At this stage of the game, when high-end-compact consumers are paying close attention to sensor size, and feeling annoyed with attempts to obfuscate that spec, what justifies calling this new size anything other than “1/1.4″, for easy comparison to other compact sensors? The only thing “2.2/3″ conveys is “We are trying to bullshit our customers; please do not read reviews or ask your digital-photography-enthusiast friends about our product before buying; just spend the money. Plz?”
Second, when did processing “green” pixels (ie, pixels with a green filter in front of them) in a manner different from the way other pixels are processed become “sensor” technology? Come on, that’s not sensor technology, that’s software or DSP technology.
Granted, Panasonic has managed to do some impressive things with software/firmware/DSP advances that other makers haven’t caught up with yet, but could we please refrain from deep-throating the press release and pay a little more attention to the difference between hardware and software?

3 years ago |2/3″ is a very well-known sensor size and when they say 2.2/3″ it means slightly larger than the 2/3″. under the same nomenclature, the 4/3″ sensor got its name, we just need to know what each size means 2/3″ is a sensor with a 11mm diagonal so if 4:3 in aspect, that translates into 8.8×6.6mm. since 2.2 = 2 x 1.1, all the dimensions of the 2.2/3″ can be estimated by multiplying the 2/3″ dimensions by a factor of 1.1x, eg instead of the11mm diagonal of the 2/3″, the 2.2/3″ has 11mmx1.1=12.1mm diagonal. predictably also the dimensions of 4/3″ can be deduced approximately from those of the 2/3″, using a multiplication factor of 2x . and although it is mathematically correct, no one calls the 2/3″ sensor 1/1.5″.

3 years ago |Sounds quite good to me… 2/3″ is a respectable size for video capture (wasn’t star wars 1 shot on 2/3″?), so 2.2/3″ is slightly better.
Can anyone clarify the 4k/2k dual resolution comment?

3 years ago |4k/2k seems to refer to a sensor that is 2k across (eg: Full HD at 1920 pixels) that is read using the technique they’re talking about. The Blue and red sensors are read giving you 4k (2k blue, 2k red) and then every fourth frame the green sensors are read (2k green).
