“…In consequence, the area within the sense region that effectively absorbs the radiation is determined, among other factors, by the angle of incidence. 13 On the other hand, the greatest leakage rates should occur when the radiation is absorbed the closest to the register region, which, in turn, happens for large solid angles.…”

We analyze in detail the apparent violation of the reciprocity law that occurs for an interline CCD array owing to its responsivity that varies with exposure time, and we investigate other parameters having an influence on this variation, such as the numerical aperture of the system or the illumination wavelength. The variation can be explained from a qualitative point of view by the charge leakage that occurs from the sense region to the register region during readout time. This change of the responsivity can be avoided either by using a synchronized external shutter or by limiting the numerical aperture while keeping relatively high exposure times. A detailed characterization for each particular CCD model must be carried out if it is to be employed in low-uncertainty radiometric measurements.

Digital photography, with the advent of reasonably priced mega‐pixel digital cameras and high quality inkjet printers, is starting to challenge conventional, silver halide based imaging systems in the profitable consumer markets. This article is designed to provide a systematic review of all the technologies required to support digital photography. The digital imaging chain provides the flow and structure for reviewing the important imaging technologies including camera optics, imaging sensors and architectures, sensor speed, color reproduction, compression, image processing and digital hardcopy. In addition to the evaluation of individual imaging technologies, a systematic, system‐wide image quality assessment is provided that takes into account image quality (sharpness) and the most common image artifacts associated with digital photography.
