Image/VGA-400
Image/VGA-400 Picture

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.
