Key Hardware Features
The DT3154 is an RGB (red, green, and blue) frame grabber board for
the PCI bus. It is suitable for both image analysis and machine vision
applications.
Key features of the DT3154 board are summarized as follows:
• Operates as a PCI bus master;
• Supports real-time image transfer to system memory;
• Supports RGB NTSC and RGB PAL video formats;
• Digitizes a 24-bit RGB input from one of two video input
channels (each consisting of separate red, green, and blue
signals);
• Can digitize two 8-bit monochrome signals of an input channel
simultaneously to provide progressive scan capability;
• Can digitize three 8-bit monochrome signals of an input channel
simultaneously;
• Supports single and multiple frame acquisitions for both color
and monochrome images;
• Supports programmable region-of-interest (ROI);
• Provides real-time, interpolated scaling to any size;
• Provides a 256 x 8-bit input look-up-table (ILUT) for each signal
(red, green, and blue) corresponding to each input channel;
• Synchronizes to one of seven sources: the red, green, or blue
signal corresponding to either input channel or to an external
sync input;
• Provides a sync output for driving camera timing;
• Provides fixed Sync Sentinel with an enable/disable option for
VCR compatibility;
