System detects color changes
CV-751 machine-vision controller uses shade-scale ASIC-based processor for enhanced color recognition and detection without requiring a PC or complex software. The processor detects color differences in hue and density as shade levels by performing 360° high-speed image rotation as part of the pattern-matching process. It can store up to eight screen images in separate built-in memory. Menu-driven user interface includes storage of Setup Menu to restore parameters such as camera focus and brightness adjustment. Other features cover 0.1-pixel measurement, illumination adjustment and normalized correlation against image illumination changes, and data recording analog output.
