Start with features found in more expensive boards.
The CX family of video frame grabbers are precision image capture boards in the ISA bus configuration. Each board has a digital synchronization scheme which delivers a rock solid image and an industry leading sampling jitter of just
+/-3 ns for detecting image details at the sub-pixel level. Video noise is 0.7 least significant bit (LSB) out of 256 gray levels to meet the most demanding applications.
The CX family provides real time capture to true dual port video RAM mapped into the computer's memory. This allows fast, non-destructive, random access to a captured image even during capture and display. Composite display output is available for viewing live video or a captured image on an external monochrome monitor. Text and graphics can be displayed on top of a live video or captured image with the optional overlay RAM, which provides 15 selectable gray levels.
The CX family supports standard RS-170 (NTSC) and CCIR (PAL) video formats, with format auto detect and auto switch. Single images of 512 x 486 pixels (RS-170) and 512 x 512 (CCIR) or four images at half resolution can be displayed. They also support hardware controlled field or frame grab, software adjustable offset and gain, and automatic look up table (LUT) load. Input and output LUTs allow gamma correction, contrast and brightness adjustment, and thresholding in real time.
We know your application. And what it takes to make components play together. From manufacturing automation to security systems and quality control, <%=company%>'s products are designed to integrate easily into your application with seamless results. The CX family provides support for needs like these:
Resettable cameras work in tandem with the CX family to capture a full frame or field without losing a bit of information.
Strobe output offers software control over cameras, strobe lights and other external equipment, with trigger input for synchronizing image acquisition to an external event.
<%=company%> gives you tools and assistance to speed development and shorten time to market.
The CX family's simple yet elegant software interface and well documented software libraries enable you to build your application quickly, with support for DOS, Windows 3.1, Windows NT, Windows 95, Watcom 32-bit as well as standard languages including C/C++ and Visual Basic. Sample application source code takes the trial-and-error out of programming: you can have your hardware up and running almost immediately.
Technical support as well as current software and examples are available through <%=company%>'s web site. Or call toll-free to talk directly with our design engineers if questions arise.
We make it our business to make yours successful.
<%=company%> can help you design the optimum vision system for your application, drawing on our years of experience and technical expertise.
<%=company%> offers a variety of frame grabber formats to help you migrate to another platform as you ramp up for volume applications. For example, the CX Family is available in the standard desktop ISA half-slot design and in the embedded PC/104 format.
Your software investment is also protected because no rewrite is required if another form factor can better satisfy your price and performance requirements in the future. <%=company%> also has a family of products with similar features for the high speed PCI bus.
Finally, <%=company%>'s team of vision system specialists stand ready to provide fully integrated MV systems or subsystems, custom designed to meet all your unique application requirements.
