ROSEMONT, IL and Natick, MA, June 3, 2003—Cognex Corporation (NASDAQ - CGNX), the world's leading supplier of machine vision systems, unveils the CDC-200™ today at the International Robots and Vision Show. The CDC-200, the newest member of the digital CMOS-based CDC camera series, extends the range of vision applications with faster frame rates and global shuttering capabilities. “The CDC-200 takes CMOS sensor-based machine vision cameras to a whole new level,” says Justin Testa, Senior Vice President of Marketing for Cognex. “With global shutter capability and faster frame rates, the CDC-200 brings high resolution image acquisition to high speed, moving applications, without sacrificing image quality or performance. At roughly half the size and weight and twice the speed of typical CCD-based high resolution cameras, the CDC-200 is ideally sized for use in space-constrained environments.” Additionally, the CDC-200 camera can accommodate mixed-resolution applications using a configurable ROI (Region of Interest) acquisition feature. This feature allows users to optimize vision application performance by defining a region of interest of any size anywhere within the possible field of view. For example, the CDC-200 can deliver high-resolution SXGA images (1280x1024) at up to 26 fps (frames per second), a standard VGA image (640x480) at frame rates up to 100 fps, or a 320x240 image at frame rates up to 340 fps. Tuning image resolution in this way allows users to maximize the frame rate, while minimizing the amount of data that must be acquired and transferred across the PCI bus. Moreover, users can reduce system cost and optimize performance by specifying ROI size and location to change image resolution on the fly. This eliminates the need for multiple cameras to view parts of different sizes under different magnifications. For example, an electronic component placement system can view large leaded and small chip components with the same camera without sacrificing accuracy when viewing large parts, or speed when viewing small parts.The CDC-200 camera performs a direct 1:1 conversion of the digitized image, providing low noise images with no “pixel jitter”. This provides the machine vision system with better image data for making decisions, such as where an object is located and whether it is defective, thus maximizing the performance of industry-leading Cognex vision software. The CDC-200 camera is designed for use with the Cognex MVS-8100D frame grabber. The 8100D features a full library of proven vision software tools, including the industry-leading Cognex PatMax® technology for locating objects despite changes in angle, scale, or appearance. Available in one, two, and three channel configurations, the 8100D enables interchangeability of any combination of up to three CDC-50, CDC-100, and CDC-200 cameras, eliminating the need to purchase multiple frame grabbers for different camera types. Asynchronous acquisition support enables each camera to accept triggers and acquire images independently of one another.Planned availability for the new CDC-200 Series CMOS-based digital camera is scheduled for Q3’03.Cognex Corporation designs, develops, manufactures, and markets machine vision systems, or computers that can "see." Cognex is the world's leader in the machine vision industry, having shipped more than 175,000 vision systems, representing over $1.3 billion in cumulative revenue, since the company's founding in 1981.
