VIDEO FRAME BUFFER (VFB)


Video Frame Buffer card is a PC- add-on board suitable for capturing monochrome video images available in CCIR format. It provides a spatial resolution of 512 x 512 pixels (or optionally 640 x 480 pixels) and intensity resolution of 8 bits (i.e 256 grey shades).

SALIENT FEATURES

  •  Selection of video input from four different sources

  • Internal synchronuos generation and automatic synchronous selection

  • On line image enhancement ( with the help of on-board Look Up Tables)

  • Frame freeze with external command OR provision of an external trigger out signal with the initiation of each frame capture
