“…the final quality of the processed image. The quantization noise is expressed in analog terms according to the following: SNR = (number of bits) x 6 + 10.8 dB (3) Some calculated values of the SNR for various number of bits are shown in Table I. The basic convention is that the SNR of the quantization noise should be 6 dB better than the dynamic range of the analog part of the camera (CCD + signal detection + linear amplification), measured at the input to the AID.…”

The architecture of CCD sensors and their relationship to digital processing of images requires a re-examination of traditional analog signal processing conventions. Digital processing now requires different methods of analysis and processing in areas such as frequency response, noise, and scanning techniques. The purpose of this paper is to encourage researchers and engineers to forget some of the traditional analog practices and have them step up to the future with an open mind. 0 1995 John Wiley & Sons, Inc.
