Description
Sensoray Model 711 frame grabber converts video camera signals into digital data required for Compact PCI computer image processing and display. Up to three cameras may be connected to the board: two with composite video and one with an S-video output. The 711 provides four digital input lines and four output lines to control camera focus, pan, tilt and triggering.
Typical Application
Frame rate
Model 711 can transfer 30 frames per second with the supplied software. It supports a variety of digital formats including RGB24 and Y8 that are directly compatible with Windows bit maps.
Synchronization
The Model 711 uses special circuitry to achieve horizontal and sub carrier synchronization to incoming video. It guarantees generation of the required pixel/line from a video source in which line length can vary by several microseconds. This circuitry allows the 711 adapter to quickly and accurately lock onto video signals, regardless of source. Since the technique is completely digital, the 711 can recognize unstable signals caused by VCR head switching and adapt the locking mechanism to accommodate the source.
Image scaling
Under software control the 711 adapter can independently scale the X and Y dimensions of the captured frame. Full-resolution video may be reduced to any size down to the size of an icon. A software-selectable digital filter is available to minimize aliasing artifacts induced by scaling.
A/D conversion
The 711's signal processor uses two flash analog-to-digital converters; one for chrominance and one for luminance. Each A/D provides 2x oversampling of the camera signal. Oversampling, combined with analog anti-aliasing filters, significantly reduces the overall sensitivity to unwanted aliasing signals and enhances the 711's digital filtering.
The 711 is capable of sending just the luminance data to the host's image buffer. This feature speed capturing monochrome images.
Camera connections
Separate BNC-style and DIN connectors are used to preserve the high-frequency components of the video signals. A single DB-type connector is used for the non-critical control signals to the camera.
