Image/VGA-400 is a single-slot
PCI board that contains an integrated frame grabber and VGA display
controller. High quality video images can be digitized and displayed
in real time inside a resizable video window on the computer's VGA
monitor. Text and graphics can be written into the VGA memory and,
using a colour key, overlayed non-destructively on top of the live
video. Chroma keying is supported so that a background can be underlaid
behind the video scene.
Image/VGA-400 is a fully
functional VGA controller. Resolutions of up to 1280x1024x 8 bits
and 800x600x24 bits are supported. The VGA graphics and video may
have different pixel depths. The VGA data can be independently double
buffered.
Image/VGA-400 provides
12V DC power through the DB-9 connector for supplying power to the
camera.
A hardware trigger allows the Image/VGA-400 to grab the next field
or next frame of video.
A capture utility that allows the user to easily grab/display a
frame of video and store/recall the frame in .tif, .tga or .bmp
file format is included with the board. A software developer's kit
that allows full board control along with sample source code examples
is available.
