Paper Abstract

This paper describes four state-of-the-art digital video cameras, which provide advanced features that benefit computer image enhancement, manipulation, and analysis. These cameras were designed to reduce the complexity of imaging systems while increasing the accuracy, dynamic range, and detail enhancement of product inspections. Two cameras utilize progressive scan CCD sensors enabling the capture of high- resolution image of moving objects without the need for strobe lights or mechanical shutters. The second progressive scan camera has an unusually high resolution of 1280 by 1024 and a choice of serial or parallel digital interface for data and control. The other two cameras incorporate digital signal processing (DSP) technology for improved dynamic range, more accurate determination of color, white balance stability, and enhanced contrast of part features against the background. Successful applications and future product development trends are discussed. A brief description of analog and digital image capture devices will address the most common questions regarding interface requirements within a typical machine vision system overview.
