1. The captured image's dimensions and whether it is monochrome or color. Larger images and color images require more processing, and the display may be slower.
2. Whether the image is enhanced or colorized via lookup tables. Enhancements require more processing, and the display may be slower.
3. The S/VGA resolution, and the displayed image's relative size. Higher resolution S/VGA displays require more data, and the display may be slower.
4. Whether the displayed image is the same (pixel) size as the captured image, and whether the display is in monochrome mode or color mode. Resizing images requires more processing, and the display may be slower.
5. For color video, whether the PIXCI® SV4 is generating YCrCb, using 2 bytes per pixel, or RGB using 3 bytes per pixel. The YCrCb uses less PCI bandwidth for capture, but must be converted into RGB by the processor. The RGB uses more PCI bandwidth for capture, but no extra processing is required.
6. The speed of the PC. Processor speed, memory caches, and PCI bus bandwidth all have an effect.
7. The speed of the S/VGA card.

The tables at right show display performance using XCAP for Windows 95.

Under Windows 95, selected S/VGA cards can receive images directly from the PIXCI® SV4, providing full, live, video display for images of any size; request the Live Video & Overlays for Win 95 Tech Tip for additional information on this feature. Capturing into PC memory has the advantage of allowing simultaneous processor access to the pixel data; sending video directly to the S/VGA card does not allow access to pixel data.
