THE METRIC IMPACT OF REDUCTION OPTICS IN DIGITAL CAMERAS

The recently released Nikon E2 still video camera incorporates reducti on optics technology which enables a full conventional 35mm image to b e recorded on a 2/3 inch (17mm) CCD army. This paper investigates the metric impact of reduction optics through application of the technique of multisensor system self-calibration. The influence of the JPEG ima ge compression facility contained within the E2 is also assessed in an overall evaluation of the camera for vision metrology applications wh ich demand relatively high object point triangulation accuracies.
