The new Euresys Domino series of analog frame grabbers are
based on a proprietary patented technology called D3
(pronounced D-Cube). D3 stands for Digital Domain Decoding.
This innovative technology is applicable to all analog cameras
and brings the analog acquisition to its highest quality level.
|
|
In classical analog frame grabbers, complex analog circuits
(such as filters and phase-locked loops) using analog components
are used to extract the horizontal, vertical and pixel synchronization
information from the composite video signals being acquired.
The analog components used are imperfect by nature. Such circuits
often require calibration because of the variability of their
characteristics. In addition, their performance may degrade with
time or temperature.
|
|
In the new Euresys Domino frame grabbers
implementing D3 Technology*, the input video signal is immediately
digitized with a very high accuracy and a high frequency.
Analog conditioning of the signal is reduced to a minimum and all
signal processing tasks traditionally performed by analog circuits
are now carried out in the digital domain. This includes digital
signal recovery tasks such as the detection of the black level,
the horizontal and vertical phase determination and the generation
of the sampling clock. The D3 engine also implements selectable
low-pass filters, optional color sub-carrier removal, high dynamic
gain and offset control and sampling of the signal to any programmable
resolution.

The all-digital approach has obvious advantages
|
|
-
The noise in the image is significantly reduced thanks to the
immediate digitizing of the signal. A perfect digital image is provided.
-
More importantly, high-quality, jitter-free images can now
be acquired from composite video signals, without the need for
additional synchronization signals or a pixel clock, thus drastically
simplifying the cabling and increasing the reliability of industrial
applications.
-
Similarly, video signals degraded by noise interference
(such as found on factory floors) can now be acquired with higher
robustness and accuracy.
-
New highly-integrated field-programmable components allow for
an efficient implementation of D3 Technology*,
leading to compact, flexible and cost-effective frame grabbers.

DOMINO Melody™, DOMINO Harmony™ and DOMINO Symphony™
|
|
The Domino Melody, Harmony and Symphony are the members of the Domino series using the D3 Technology*. They are
compatible with industrial analog cameras, be they including single-tap or RGB. They support multiple speed and megapixel
progressive-scan video signals, asynchronous reset of the camera with external triggering and exposure and light
strobe control.
