Hi all,
The latest (April) copy of the British (amateur ) electronics
magazine "Electronics (nee Wireless) World" has a rather poorly written
article entitled "Digital Camera Developements" . However in the article
there is some tantalising information on the Olympus "SHD-S1" prototype. They
refer to it as a medium format camera with three 2048x2048 CCD's. In other
words it is a beam splitter design with 12 total mega pixels. I doubt it
really is medium format from their description. It has 12 bits per color for
48bits color depth. It has a large pivoting LCD monitor which mounts atop the
camera.
Here are some other OT items:
The article does discuss some things to do with temperature compensating the
CCDs and the resulting loss of pixels to dark current compensation. They
also discuss Minoltas Dimage 1500 that has interchangeable sensor to allow
resolution upgrades and a interchangeable lens.
A Fuji/Nikon collaboration where a small CCD is combined with "condensor
optics" and conventional Nikon lenses. It is not clear from the diagrams
whether an image is produced at the film plane and then re-imaged with the
condensor optics (lossy) or whether something else like a fibre optic plate
etc is being used. The claim is the concentration of light gives higher
effective "film speed" (better s/n ratio) from the small CCD.
Umax is producing a new 30 bit CMOS camera with a four color sensor for
better color rendition. It uses R G B and Teal (~green blue). It is only 800k
pixels.

Tim Hughes
