Atmel Targets High Definition Digital Image Applications with Launch
of Its 8-Million-pixel Full Frame CCD Image Sensor
Monochrome and Color providing system designer with high dynamic
range
Grenoble, France ¨C February 11, 2003. . . Atmel® Corporation
(Nasdaq: ATML) announced today the launch of the AT71200M CCD, 8-
Million-pixel full frame area arrays. The large format (35mm film
compatible image format), high definition and high dynamic range make
the device suitable for any application requiring high image
accuracy. This full frame imager is designed for the Graphic Arts
marketplace such as digital minilabs, retouch/enhancement stations,
high resolution reprography, large format X-ray film scanning and
high resolution microscopy applications.
The imager features 2300 (H) x 3500 (V) pixels, each with large
10x10µm pixels. It has 100 % aperture, which provides a large
bandwidth of response up to 1100nm wavelength, for the monochrome
version. There is a bayer standard RGB color mosaic, specially
designed for colorimetric applications, with the three colors
balanced for a 4500 degrees-K standard illuminant.
The AT71200M CCD main characteristics include very low dark current
(MPP mode) and a high dynamic range of 12 bits at room temperature.
With flexible operating moes, the imager is suitable for a wide range
of applications. The CCD is split into four independent zones that
are driven separately by four phase clocks. Thus the sensor can be
used in up to 12 sensor modes. Two serial registers and four
independent output amplifiers offer a high-frequency functionality of
up to 10 frames/second using 4 outputs at 25MHz. The AT71200M CCD
sensor is able to work in 1x1, 2x2, 4x4 binning mode (at full
saturation) and in ROI structure ( Region of Interest

Minolta, of usually it has the dynamic range 1000 times that or more
CCD
Developing the "video rate corresponding VGA color CMOS area image
sensor"
2003 March 12th
The Minolta corporation
The Minolta corporation (president: Yosikatu Ota), it exceeds 1000
times that usual CCD, it hasthe dynamic range of 10^6 or more,we
inform about the fact that the "video rate corresponding VGA
colorCMOS area image sensor" was developed.
The image sensor is being used recently, as a input equipment of
various uses. Then it has reached the point where the light absorbent
section (the photodiode) the light which incidence is done, it
converts the general CCD image sensor which is used mainly, to the
electron of the quantity which is proportionate to that light
intensity, integrates that in the photodiode section, consecutively
outputs. Because of that, because the dynamic range it is restricted
by the capacity of the photodiode, there was a problem that, it is
the times when the part which the bright part flies white, is dark
collapses black actualization of the wide dynamic range image sensor
was strongly desired.
As for Minolta in 1999, adding the log amplifier each every pixel,
the incident light intensity by the fact that it converts to the
voltage of the quantity which is proportionate to the logarithm of
integral calculus value of that light intensity, withthe
loamcorporation being joint it developed and announced the CMOS area
image sensor where you can obtain the dynamic range of 10^5 or more.
As for this, solar light and the headlight of the car or the very in
welding process bright illuminant etc. going inside the picture,
without the dark space collapsing, to detail it is something which
can reappear faithfully.
This corporation sold this sensor, in 2001, for the one for business
whose photographing record of high brightness subject is possible it
is loaded onto also logarithm conversion type video camera "LS-2002".
As for the sensor which this time was developed, 10 times that or
more those of previous announcement, usually CCD (10^3) being
something where you can obtainthe dynamicrange of 10^6 or more, it
exceeds much it does. In addition, it reached the point where it can
obtain many information with smooth image by corresponding to color
conversion and VGA and video rate. Furthermore, by the fact that
individual pixel circuit constitution and drive method is adopted,
being automatic in every pixel, the change, the brightness time at
the time of CCD similar linear output and high brightness logarithm
conversion output low it became possible to do, (rough sketch
reference). Because of this, while actualizing the wide dynamic
range, high contrast it can obtain the picture and satisfactory color
reproducibility concerning low the brightness subject inside the
picture.
In addition, everything to consist of CMOS structure, because power
supply voltage, can set each consumed electric current low in
comparison with CCD, at the time of the developing to portable
telephone PDA and the like, it is possible to utilize the quality
sufficiently.
Furthermore, the experimental model of the wide dynamic range CMOS
camera which uses this sensor is held, 2003 March 14th (the gold)"¥ª¥×

Hamamatsu congress center) we exhibit.
< Applied example of this sensor >
1. Supervisory camera
From the window and the door where solar light enters directing to
outside, it can correspond also installation.
2. ITS (high-level traffic management system) related picture input
camera
It can correspond in entrance west day and the like of headlight &
tunnel of oncoming car of nighttime.
3. The camera for FA
Be able to use for the observation of the material whose reflectance
ratio is high, in addition, it can utilize even in the automatic
operation distinction with lust information.
4. The picture input camera for portable telephone PDA
Under solar light, to the backlight scene, the place of the camera,
direction is not chosen from the interior.
5. Medical application camera
When there is a regular rfelection with the mucous membrane and the
like, photographing is possible appropriately.
< Main merit >
1. The opticaldynamic range which exceeds 10^6
It is low, the scene where subject of brightness high brightness
exists together, without changing the contraction, it can take under
identical exposure conditions.
2. Increase of the amount of information with color conversion
It can obtain the lust information which has the dynamic range of RGB
each color 10^6 or more by adoptingthe RGB primary color color
filter, in addition to wide-ranging brightness information.
3. The wide dynamic range by linear/logarithm drive compatibility of
high contrast
It is low, the brightness time being automatic, it can change
logarithmic compression output at the time of alignment output and
high brightness, (it substitutes ardently, as for the point optional
setting possibility). As for this change because it is done in every
pixel, in the identical picture those of high brightness, high
contrast you can obtain the picture even with when those of
brightness exist together low the to picture it can convert without
flying through high brightness subject white not only, low regarding
brightness subject can obtain satisfactory color reproducibility.
4. VGA and 30 frames/second correspondence
With the video monitor regarding monitoring, you can obtain smooth
image with high resolution.
5. Low electric power consumption it is low power supply voltage
With the quality of CMOS, in comparison with CCD, low voltage, it can
handle by electric power.
