Basic FastFrame
Framegrabber
Alacron’s Basic FastFrame Framegrabber is a multiple asynchronous
analog or digital framegrabber. The FastFrame is supported by full-featured,
highly-efficient, basic imaging functions operating in real-time
through a user-friendly C callable DLL environment for Windows NT,
Win9X, and other operating systems.
Basic FastFrame Features
- Collects data from up to three asynchronous analog cameras and
one NTSC/PAL/SECAM or up to four digital cameras
- 8 MB SDRAM buffer memory
- Input options:
- Digital, 16 data bits (RS-422, LVDS, PECL) with control
and clock
- NTSC/PAL/SECAM
- Three async RS-170 inputs or one RGB input
- Optional continuous composite NTSC/PAL and SVGA video output
- Available for PCI computers
