Abstract
Non-ideal characteristics of image acquisition systems are discussed. A model is formulated which describes the behavior of an image acquisition system, including effects of the camera, lens and frame grabber. Procedures for measuring the model parameters are developed. A procedure for inverting the model to obtain luminance measurements from frame-grabber values is given, along with a discussion of its limitations. This image correction procedure is tested for two solid-state cameras, and the results are analyzed. System noise measurements provide estimates of the reliability of the results, and the effects of averaging succesive frames to reduce the effects of noise are discussed.
