The global shutter circuitry patented by Olympus (found via Egami)
A couple of days ago I told you via trusted sources that Panasonic has the plan to introduce the “global shutter” with the next GH3 camera. And not only Panasonic is working on it! Egami spotted an Olympus patent describing the noise reduction process on a sensor with global shutter. Global shutters can remove the typical effects from current sensors using the rolling shutter like exhibit smearing,skew, wobble, and partial exposure. Wikipedia explains it better: “Rolling shutter (also known as line scan) is a method of image acquisition in which each frame is recorded not from a snapshot of a single point in time, but rather by scanning across the frame either vertically or horizontally. In other words, not all parts of the image are recorded at exactly the same time, even though the whole frame is displayed at the same time during playback. This is in contrast with global shutter in which the entire frame is exposed for the same time window.”
According to Egami the Olympus global shutter sensor will also allow to have much sharper images (you can see an image comparison on their website).
