Features
The DT3153 is a high-accuracy, low-cost, color frame grabber board
for the PCI bus. It is suitable for both color image analysis and
machine vision applications.
The DT3153 board digitizes the video signal, and either stores the
digitized data to the host computer’s system memory, or transfers the
digitized data to the computer’s display controller to display 32-bit
images in real-time. The board transfers image data to the host
computer using PCI burst transfers.
Key features of the DT3153 board are summarized as follows:
• Operates as a PCI bus master;
• Digitizes up to three composite (CVBS) video inputs using
NTSC/RS-170 or PAL video formats, or one S-video (YUV) input
using the Y/C video format;
• Acquires a single frame or multiple frames synchronously or
asynchronously;
• Stores images in either 32-bit color format (RGB) or 16-bit color
format (YUV or RGB16);
• Supports programmable region-of-interest (ROI);
• Provides real-time, interpolated scaling to any size;
• Provides Sync Master mode which, when enabled, outputs three
sync signals for driving camera timing;
• Provides programmable control of the color settings of the board,
including brightness, contrast, saturation, and hue;
• Accepts an external trigger with selectable polarity; and
• Provides four general-purpose, TTL-level digital I/O lines.
