1. FireWire & Connectivity
That‘s what the others provide:
Most digital cameras feature proprietary interfaces or need framegrabber boards. Those
technologies provide acceptable data transfer rates but at the same time poor computer co nnectivity. Working with one camera in connection with several PCs thus makes it necessary to
purchase several PCI boards or to move the board from one PC to another. Often you need
two cables for data and power.
That’s what makes the ProgRes C14 special:
The ProgRes C14’s OHCI compliant IEEE1394 FireWire interface
provides a „plug and play“ performance. One single FireWire
cable transfers data and supplies power for the ProgRes
camera. Many Windows PCs feature FireWire as a standard
interface and standard FireWire PCI boards are available for
low prices, even as PC cards for notebooks. All Macintosh computers feature FireWire interfaces as standard, the Apple
PowerBooks even with power supply.
More: for macro-photography the ProgRes C14 features a flash
sync jack and two documented interfaces for external control
and data transfer are also available.
Benefits for the user: one single cable = most easy connectivity, flexibility, mobility.
excellence through light.
Therefore ProgRes C14
2. Microscanning (also known as „Pixelshifting“) and Programmable Resolution
That‘s what the others provide:
Fixed chip cameras limt the image resolution to the sensor used. A small sensor with a low
pixel number has a low resolution and output image sizes. To increase the image output size
you can „increase“ resolution by interpolation. By interpolation no new optical image information is generated, you only blow up the data, interpolation errors may generate artifacts.
Details that have not been optically recorded remain lost. Alternatives: Increasing the chip
size. Problem: by increasing chip size (i.e. area, not necessarily pixel number) production defects will increase exponentially and thus waste and thus costs. Next guess: Keeping chip size
small but increase pixel number. Problem: a small sensor with a high pixel number has limited
light sensitivity only – resulting in low SNR and thus limited image quality.
That’s what makes the ProgRes C14 special:
The Microscanning technique used in the ProgRes cameras sucessfully for more than ten years
(!!) increases the optical resolution of small sized sensors without loss of sensitivity. The user
can set the camera’s resolution to fit his needs: low resolution for emails, quick snapshots,
poor microscope optics or high magnification microscope lenses – high resolution for detailled
images appropriate for image analysis, documentation, high quality optics, low magnification
microscope lenses.
The images below show a part of a photographed newspaper (lens: Rodenstock Apo-Rodagon
50mm, f8, distance approx. 600mm, showing a detail 5mm wide). Left image is ca ptured in
max. resolution (36-Shot, 12.1MPix) shown @200% screen enlargement, in comparison to the
right image with standard resolution (1.3MPix) shown @600% screen enlargement.
Taking into account Multi-Shot modes and the binning modes the ProgRes C14 provides in total 9 resolutions ranging from 260x206 pixels up to 3900x3090 pixels. This is unrivalled in its
class of 1.3MPix CCD digital cameras.
The only drawback to mention is, that the resolution-enhancing Microscanning technique can
only be used with still objects or absolutely non-moving specimen.
Benefits for the user: adaptable resolution from 1.3 up to 12.1 Megapixels not interpolated.

3. Microscanning (also known as „Pixelshifting“) and Color-Co-Site-Sampling
That‘s what the others provide:
CCD sensors cannot recognize colors. They can detect only differences in brightness. For recording color images digital photography offers two options. First of all, you can compose
every shade of color from the three basic colors red, green and blue (RGB).
Option 1: Color filter wheels. Cameras with colored filter
wheels capture three images of the same object, each
time placing a red, green or blue color filter in front of
the sensor. The final color image is composed from those
three monochrome images. Advantage: the full sensor
resolution is used. Major drawback: you can cannot capture moving obects.
Option 2: On-Chip color mosaic masks. This type of cameras features CCD sensors where tiny red, green and blue
color filters are placed directly on the individual pixels.
Most commonly used is the „Bayer pattern“ where rows
of alternating red and green pixels rows of alternating
blue and green pixels (see illus. on the left). Drawback:
you need at least three monochrome pixels for composing
one full color pixel, what is done automatically by the camera software. So actually the resolution should be only one third of the full sensor resolution. Usually the full sensor resolution
in full color is restored by interpolation algorithms. This sometimes may result in false color
rendition or artifacts such as color moirés when capturing certain, fine structured objects.
The main advantage of this technique: this is the only possible way to capture color images
from moving objects and thus well established in digital photography.
That’s what makes the ProgRes C14 special:
1-Shot mode: The ProgRes C14 camera is equipped with an on-chip color mask and thus enables the user to capture moving objects – freezing movement with minimum exposure time
of 1/4000s if necessary. This we call 1-Shot technique. Full color information for each of the
sensor’s pixels is calculated by a very sophisticated interpolation algorithm. Here we can
count on our experience with “eyelike” digital camera backs for professional studio photography, where demands for perfect color rendition are very high.
Multi-Shot modes: Microscanning provides additional
advantages by overcoming problems that may arise with
interpolation. Let’s have this explained with the 4-Shot
mode as an example: in the ProgRes camera’s 4-Shot
mode four images of the object are captured. In
between of each of the four captures the complete CCD
sensor with its color mask is moved or shifted a pixel’s
step by step in a square pattern. Thus one image point,
that is captured e.g. by a green pixel in the first image, will be captured sucessively by a red,
green and blue pixel in the subsequent three images.
The final image is then combined from four single images laid on top of each other. The m ajor advantage is, that by this technique you are recording full RGB color information for each
of the sensor’s pixels and thus do not need to interpolate two of three colors. In comparison
to the 1-Shot mode you could say that in principle you use full color pixels instead of onecolor monochrome pixels (with the need of subsequent interpolation). The other Multi -Shot

Therefore ProgRes C14
modes 16-Shot and 36-Shot work the same way, regarding the recording of color information –
only the resolution is different. These techniques we call Color-Co-Site-Sampling.
The 9-Shot mode is a compromise between 1-Shot and 36-Shot: The final image is composed
of 9 single images, where interpolation and Microscanning are combined. The result is a highresolution and high-contrast image that takes less time than the 36-Shot mode but lacks the
fine details you will record with the 36-Shot mode. It is suited for poorly structured objects or
specimens.
Again, the only drawback is, that the color enhancing Microscanning technique cannot be
used with moving objects or specimen.
The benefits for the user: Exact color reproduction thereby avoiding interpolation induced
artifacts such as color moiré.
4. Microscanning and Scanner Calibration
That‘s what the others provide:
Few digital cameras feature kind of Microscanning technique using piezoelectric elements for shifting the sensor. As you might guess the shifting
must be performed very precisely, i.e. with a precision of approx. 0.5
microns. This is a important prerequisite for combining the individual
Multi-Shot images to the final hi-res image. Responsible for the shifting of
the sensor are piezoelectric elements. These elements react to an applied
voltage by a slight deformation which then is used for the shifting. The
trick is to apply the right voltage to produce a certain displacement of the sensor. The trouble with such elements is, that they are susceptible for ambient conditions such as temerature and humidity. Thus the displacement can slightly differ from debit when the scanner is
operated under ambient conditions very different from the conditions the scanner has been
calibrated for. This will normaly result in visible defects in the final compound image. Under
normal conditions the manufacturer’s calibration will work fine.
That’s what makes the ProgRes C14 special:
The ProgRes C14 camera features a calibration procedure for the Microscanning technique. This can be utilized in case the user should notice loss
in image quality when operating the camera in Multi-Shot mode under
„extreme“ ambient conditions. With all cameras a calibration slide is supplied. Simply put it under the microscope, set focus and exposure, press
two buttons in the camera software and that’s it. The calibration is done
automatically by the camera and the calibration data will be memorized.
Remember that normally you do not need to re-calibrate the camera but you are able to perform the calibration by yourself if it becomes necessary.
The benefits for the user: Perfect operation of the piezo-driven scanner for perfect images.
excellence through light.

5. Cooling and Sensor Capsuling
An effective sensor cooling is essential
to reduce noise and thus increase image
quality, to improve the dynamic range
and to allow for long integraton times.
That‘s what the others provide:
Most cooled CCD cameras feature an electric cooling mechanism. Heat is removed from the
CCD sensor by a peltier device. One side of the peltier device is cooled while the other heats
up. The heat from the hot side is abducted to a heat sink. The heat sink itself in result becomes more and more hot, the heat usually is abducted by the air surrounding the heat sink
and by the camera’s housing. When the housing heats up too much and no hot air from inside
is exchanged by cooler outside air, a heat jam may occur. Another possible by-product of
cooling: the cooling below ambient temperature makes the CCD sensor susceptible to
condensation of air humidity.
That’s what makes the ProgRes C14 special:
The ProgRes C14 uses
electric cooling by a peltier
device and heat sink in
combination
with
an
additional fan. The fan is
used to remove heat more
effectively from the heat
sink by continuously replacing the warm air in the
housing by colder air from
the housing’s surroundings.
A CCD cooling of approx. 10°C to 15°C below ambient temperature is achieved this way. In
addition to this 2-fold cooling mechanism the ProgRes is designed in such a way, that electronic components generating heat (e.g. interface electronics) are seperated from the sensor.
The overall power consumption of the sensor electronics has been kept as low as possible
which also reduces heat generation to a minimum. In total, the ProgRes C14 is cooled more
effectively than digital cameras with comparable peltier cooling mechanisms, thereby resulting in a typical dynamic range of 66dB.
The image on the left compares the standard peltier cooling mechanisms. In conventional
cameras, where no fan is used, heat may be trapped in the camera’s housing resulting in ineffective CCD cooling. In the ProgRes C14 a fan removes heat from heatsi nk and housing.
Sensor capsuling: The condensation problem is solved by sealing the complete CCD sensor and
filling the sensor capsule with a dried, protective gas. Thus no condensation can occur. The
sensor capsuling has another great advantage: the CCD sensor is completely protected from
dust and other pollution from external sources. The IR cut-off filter, which is integrated part
of the sensor capsule, is placed well in front of the CCD surface and thus aditionally protects
excellence through light.
Therefore ProgRes C14
from image flaws caused by dust that sometimes and ocasionally seems to be magnetically attracted to optical devices.
The benefits for the user: An effective cooling results in high dynamics, low noise, long
exposure times and the sensor capsule protects the CCD sensor from dust a nd condensation.
6. AD-Conversion Methods
That‘s what the others provide:
AD-conversion in most cameras takes place in interface boards inside the computers. This
keeps the camera small, but there is a long way for the analogue image data signal from the
sensor to the digitizer board and thus much chance that noise will disturb the signal.
That’s what makes the ProgRes C14 special:
The AD-conversion takes place in the ProgRes C14 camera itself, near the sensor. By this
means electronic noise and other electromagnetic interferences are kept to an absolute
minimum.
The benefits for the user: AD conversion in the camera head reduces noise
thereby improving dynamics.
7. Automatic Exposure Metering
The ProgRes C14 features an automatic exposure metering tool that evaluates the image
area’s exposure and sets the exposure time accordingly. The automatic function achieves excellent results under most imaging and illumination conditions. The automatic exposure fun ction is especially worthful for flourescence applications where there is no time to set the exposure time manually by trial and error. A simple click on a button does the measuring and
setting of the correct exposure time automatically.
8. Software
That‘s what the others provide:
Few cameras are delivered with specialized software, some only with software for a certain
computer operating system, some provide highly sophisticated and expensive features, others
lack of basic image processing functionalities.
That’s what makes the ProgRes C14 special:
Just a few keywords for a start: ProFile, TWAIN, Photoshop, Windows, Macintosh, automated
