Informational representation of fundamental phenomena in the digital electro-optical imaging devices

摘要

This article contains basic theoretical results of mathematical interpretations of some fundamental phenomena in the modern digital electronic (electro-optical) imaging devices (systems) with pixel photodetection structure mainly from the standpoint of the mean mutual information. For that purpose, the systems in question are approximated by a suitable linear and isoplanatic signal transfer model of a 2D stationary and ergodic continuous stochastic distribution of the object scene -light intensity which is limited in size by the input field of view. The mathematical modelling of the phenomena presented is based on utilizing the continuous linear signal transfer theory and the extended modern communication and information theory for the spectral domain of spatial frequencies, in particular. The equations put forward are acceptable for an analysis and optimal synthesis of digital electronic imaging systems fitting the signal transfer model proposed. Conventionally, these systems give better information efficiency and image quality in comparison with the older analog imaging systems.
