Default New Panasonic Sensor Technology:

This is a must read for all those into Sensor Technology from Panasonic:
http://www.eoshd.com/entry.php?29-Pa...xposure-sensor

Panasonic engineers reveals workings of GH2 'dual exposure' sensor.
Here are the key points:
  • Panasonic have developed a 4K x 2K image sensor (approx. 12 megapixel) based on 'dual exposure technique'
  • The sensor is described as having new architecture that tries to improve sensitivity by a factor of 4 or more
  • The architecture change is a new design which allows green pixels to be read independently of the blue and red ones on the sensor.
  • The green pixels are exposed 4 times longer than the red and blue, thus achieving the sensitivity gain
  • Motion artifacts are introduced as a result, but clever signal processing of the red and blue channels corrects the motion artifacts introduced in the green channel by the long exposure
  • Red and blue channel gain achieved by pixel binning in 4x4 mode.
The fun part:
"A factor of 4 increase in sensitivity will allow the Micro 4/3rds camera to surpass the full frame Canon 5DMkII".

dbnnet-

Many thanks for the link. It was an interesting article. It also seems to verify that Panasonic has put full emphasis on the G series cameras.

Have a great weekend.
