Acquisition:
The PC2-Vision acquires from standard and non-standard
monochrome and RGB analog sources. It's A/D converter
can digitize up to three synchronized monochrome cameras.
Alternatively, simultaneous acquisition is supported
through a frame delay mode feature allowing concurrent
capture from all six inputs to increase camera interface
flexibility. The PC2-Vision
features anti-aliasing filters with cutoff frequency
of 6MHz or 12MHz that are software selectable and a
filter bypass option. A high accuracy 40MHz triple-channel
8-bit analog to digital converter offers gain and offset
control to precisely match the video voltage level of
the camera.
Acquisition Control Unit:
The Acquisition Control Unit (ACU) is a core technology
on the PC2-Vision that manages the synchronization of
all camera functions, including camera-timing controls.
Each of the six camera inputs has its own VS, HS, frame
reset and WEN signals. This offers remarkable flexibility
in the way cameras can be interfaced to the PC2-Vision.
The ACU is able to generate timing information to cameras
through those signals enabling the frame grabber to
become the timing reference ('master') of the vision
system. This feature is useful as it allows cameras
to easily genlock together. In addition, a robust sync
extractor permits recovery of signals from the most
difficult synchronization sources.
Camera Link™
Camera Link™ is a newly adopted standard for high-speed
serial data transmission created by an alliance of camera
and frame grabber manufacturers. Camera Link was developed
to address the problems long associated with digital
cameras such as high cable costs, short transmission
distances, and non-standard interfaces. Based on the
high-speed serial LVDS interface developed by National
Semiconductor, the on-board Camera Link interface provides
a fast, easy-to-use way to connect to high-speed digital
cameras. The fact that Camera Link is a serial interface
vs. the previously used parallel interface, pin count,
cable diameter, and cable costs are greatly reduced.
Successful transmission distances of up to 10 meters
can be accomplished.
