The DT3120 is a low-cost, color frame grabber board for the PCI bus.
This board is suitable for both color image analysis and machine
vision applications.
Each DT3120 board digitizes the image, then 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 images
in real-time. The board transfers image data to the host computer
using PCI burst transfers.
Key features of the DT3120 board are summarized as follows:
• Operates as PCI bus masters on half-size board.
• Supports the scatter/gather memory capability using the PCI
interface chip.
• Supports one monochrome or composite video input, which uses
the NTSC/RS-170 or PAL/CCIR video format, or one S-video
signal, which uses the Y/C video format.
• Accepts a software or external trigger.
• Acquires single or multiple fields and/or frames synchronously
or asynchronously.
• Stores images in either 32-bit RGB, 16-bit RGB, 15-bit RGB, 16-bit
YUYV422, or 8-bit monochrome format.
• Supports programmable region-of-interest (ROI).
• Provides real-time, interpolated scaling to any size.
• Provides programmable control of the color settings of the board,
including brightness, contrast, saturation, and hue.
• Supports overlays.
