The DT3157 frame grabber accepts video from digital input sources.
It is suitable for both image analysis and machine vision applications.
Key features of the DT3157 board are summarized as follows:
• Operates as a PCI bus master;
• Accepts 8-, 10-, 12-, 14-, or 16-bit monochrome video from a
single RS-422 video channel (programmable to 2 KB x 2 KB, 4 KB
x 1 KB, or 1 KB x 4 KB), or 8-bit monochrome from two RS-422
video channels (programmable to 1 KB x 1 KB);
• Supports Kodak dual 8-bit video format (such as the Model
ES1.0);
• Supports up to 20 MHz on a single channel (8 to 16 bits), and
40 MHz for dual channels;
• Provides real-time image transfer to host memory or to the
display frame buffer;
• Provides real-time scaling, using decimation, up to 1/16 size
(except in dual-channel mode);
• Accepts an external trigger;
• Provides an input look-up-table that supports single- and
dual-channel mode;
