Basler
Introduces a High Dynamic Range Camera
|
More information
Ahrensburg,
January 27, 2004 Basler Vision Components (Basler-VC) has successfully introduced a
new line of area scan cameras, the A600f series. These CMOS sensor based cameras have a
full frame shutter, an IEEE 1394 interface, a very small housing, and can operate at up to
100 frames per second at full 656 x 491 resolution.
Because CMOS sensors do not have the blooming or smearing seen with CCDs, A600f cameras
are good candidates for outdoor applications. The new High Dynamic Range (HDR) version of
the A600f is especially suited for outdoor use. The A600f-HDR grabs multiple frames with
different exposure times and combines the collected gray values to create a single high
dynamic range image. Using this technique, the A600f-HDR is able to simulate a range of up
to 112 dB. Even with this high dynamic range, the signal-to-noise ratio for each gray
value is very good compared to a purely logarithmic sensitivity curve. The cameras
frame rate depends on the required dynamic range, for example, a 53.3 fps rate can be
achieved with a 48 dB range and an 8 fps rate with a 112 dB range.
The output signal can be a linear 16 bit signal (limited) or an exponential format (8 bit
base, 8 bit exponent). To allow visualization of HDR images on standard 8 bit monitors, a
software tool with Laplace and tonemap conversions is available.
Basler-VC designs and manufactures advanced vision components for industrial users.
Products include color and monochrome line scan and area scan digital cameras for high
speed and/or high-resolution applications. Product designs are driven by industry
requirements offering easy interfacing, compact size, and a strong price / performance
ratio.

Ahrensburg, March 1, 2004 The Basler A600f
camera family, already a very powerful product line, is being enhanced with valuable
new features. More intelligence and performance are moving from the PC into the camera.
These improvements will debut in the A600f series and will be extended to Basler's other
IEEE 1394 products opening many new camera applications.
The power of the electronic components used in Basler IEEE 1394 cameras now allows
real-time transmission of both basic image data and additional image parameters such as
the position and size of the area of interest (AOI). On-the-fly changes in AOI position
can be realized for fast tracking of ob-jects. A frame counter, a precise time stamp, and
a list of general parameter settings including absolute exposure time, gamma, gain,
offset, and white balance values can be added to the basic image data and sent to the PC
with 32 bit accuracy. Because the image content is more than 99% of the whole package, the
effect on the camera's frame rate is negligible. An op-tional checksum (CRC) proves that
extended data transmission via the IEEE 1394 bus is safe. The cameras also feature user
configurable I/O ports (4 of each) which add flexibility in industrial applications.
The feature-set and properties of the A600f
make it an ideal candidate for nearly all digital camera applications. Once again, Basler
is showing a keen sense of the requirements for machine vision, commented Dr.
Joachim Linkemann, Vision Components Product Manager. By moving many pre-processing
tasks into the camera, we have established an ideal basis for customized solutions.
