Improvements in sensor technology as well as in optics and electronics technologies have elevated digital still cameras (DSCs) to levels of quality comparable to those of film cameras. This book acquaints both current and next-generation engineers with the concepts, applications, and future directions of digital image acquisition and signal processing technology in DSCs. Expert contributors present the historical background and current state of the field, the optics used, particular image sensor technologies and how each affects image quality, methods for evaluating performance relative to requirements of DSCs, implementing image processing algorithms, and the probable future directions of the field.
