Description

Model 311 is a PC/104+ board that captures uncompressed video from one analog NTSC/PAL input. It has four video inputs that allow up to four composite, or three composite and one S-video source to be connected to the board. A programmable video switch selects the input to be captured. Eight general-purpose digital I/Os (four in, four out) are provided for applications such as capture triggering and camera/illumination control.

Frame rate

Model 311 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 bitmaps.

Synchronization

The Model 311 uses special circuitry to achieve horizontal and subcarrier 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 311 adapter to quickly and accurately lock on to video signals, regardless of source. Since the technique is completely digital, the 311 can recognize unstable signals caused by VCR head switching and adapt the locking mechanism to accommodate the source.

Image scaling

Under software control, the 311 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 311's signal processor uses two flash analog-to-digital converters; one for chrominance and one for luminance. Each A/D provides 2x over sampling of the camera signal. Over sampling, combined with analog anti-aliasing filters, significantly reduces the overall sensitivity to unwanted aliasing signals and enhances the 311's digital filtering.

The 311 is capable of sending just the luminance data to the host's image buffer. This feature speeds capturing monochrome images.
