The Pixel shift tech from the Hasselblad H5D-200c. Something similar is coming from Olympus.
An anonymous source sent me a precious info that I luckily could confirm via one of my best trusted sources. So here is the big news:
The new Olympus camera coming during the first week of February will be called Olympus E-M5II (or E-M5 Mark II). And the big new feature of the camera is “sensor shift” shooting. The camera has a 16 Megapixel sensor that can shoot up to 40 Megapixel by shifting the sensor (in up to 8 frames of single shots).
The sources didn’t explain me in very detail how it works but my guess is that it works in a similar way of the Hasselblad H5D-200c. Hasselblad (Pdf file here) describes the tech in that way:
High precision piezo-electrical actuators control movements of the sensor in ½ and in one pixel increments. By combining six shots, offset by a combination of both ½ pixel increments and one pixel increments, the colors, Red, Green and Blue of each point are obtained with a double resolution in both the X and Y directions. The result is an astonishing 200Mpixel full color image with no artifacts, such as moiré.
The Bayer Mosaic filter pattern covers the pixels of the sensor. Moving the sensor in one pixel increments between shots, allows for the exact R, G, B values to be captured in every pixel. The multiple captures are then assembled to deliver the correct colors and ultimate definition of detail. Adding captures, each offset by a ½ pixel sensor movement, creates space for extending the sensor resolution from 50Mpix to 200Mpix. The outstanding definition of color and detail is maintained
Olympus will likely use their own 5 axis stabilization system to achieve that micro-sensor-shifting. Just like you create HDR images from multiple shots you can create a high-resolution image. The BIG question here is how good it works when you take a picture of non static subjects like people and so on.
Anyway, I hope to get more details about the tech works during the coming weeks. In the meantime I Thank the anonymous source for sending me this info and the trusted source for confirming that it’s correct! I do hope you will teach me mroe about that new special Olympus tech if you can
