had a large-format, rectangular color sensor developed exclusively for its program.
With its resolution of more than 22 million pixels, it achieves an increase
in quality never reached before now.
At present, modern prosumer digital cameras that work exclusively in the 1-shot
mode use mostly thumb-sized sensors with 5 or even 6 megapixels (MPx) derived
from video technology, which yield quite acceptable results. But now as before,
demanding tasks that can only be solved with professional flexible systems require
larger, qualitatively superior full-frame CCD sensors.
After 1998, 6 MPx sensors were regarded as state of the art (. Sinarback 23).
Just over a year ago, a square sensor with approximately 36 mm sides square
format became available, which featured an impressive 16 MPx (. Sinarback 44).
But most applications, like advertising photographs, posters, books, reproductions,
etc. usually involve rectangular formats, so that they can only use 11 of the
16 million pixels. Transforming this disadvantage into a benefit, certain new
systems were introduced this summer, featuring a rectangular-shaped sensor with
11 MPx in a small format (. Sinarback 43).
The new KAF-22000CE full-frame CCD image sensor, specified and developed by
Kodak in cooperation with Sinar is the only one that progresses logically towards
large format photography and high resolution. This sensor is built with the
latest technology available, significantly improving image quality by setting
a record in resolution for the photographic industry.
At the same time it offers additional benefits such as a new color pigmentation
for improved color stability, and wider dynamic range, which combined with the
high resolution and large optical format, results in unrivaled photographic
Sinar is the only company that has a large-format sensor with a resolution
of 22,195,200 pixels. With regard to the rectangular format, this is equivalent
to double the resolution as compared to any other photo sensor currently available
or announced on the market.
The KAF-22000CE CCD image sensor, which is tailored specifically to Sinar
requirements, features 4080 x 5440 pixels, each with an edge length of 9 .
This 4:3 aspect ration rectangular sensor has a total silicon surface area of
38.8 mm x 50.0 mm. This makes this sensor suitable for applications as a digital
replacement of film in modern 645 medium format camera systems, without the
need for significant changes in focal lengths.
The new KAF-22000CE sensor will be highly advantageous in action- as well as
still life photography. In photographs made in the 1-shot mode (portraits, people,
landscapes and numerous other applications), every pixel counts in the prevention
of color interpolation errors, edge artifacts and moir effects. The
impressive superiority of the new 22 million pixels sensor will have a dramatic
effect on all these applications because, compared to an 11 MPx sensor, there
is twice the information available to record the subjects subtleties.
The finest textile structures, hair and other moving details with strong contrasts
will now be reproduced perfectly, eliminating the need for subsequent manipulation.
Thanks to the large sensor surface, optimal use is made of the image circle
and lens resolving power. It is also ideal for medium format cameras. This large
format makes perfect wide-angle photographs possible again with medium format
lenses and now it is feasible to use the high-resolution digital sensor the
same way rollfilm 120/220 is used. This sensor has also been conceived for applications
with Sinar view cameras, so that professional photographers can look forward
to digital film material that can be used universally for every
photographic task. With its unequalled resolving power of more than 22 million
pixels, such an image can be used for virtually any purpose.
