This article contains basic theoretical results of mathematical interpretations of some fundamental phenomena in the modern digital electronic imaging systems with pixel photodetection structure mainly from the standpoint of the mean mutual information. For such a purpose, the mentioned systems are approximated by a suitable linear and isoplanatic signal transfer model of a two-dimensional stationary and ergodic continuous stochastic distribution of the object scene- light intensity which is limited in size by the input field of view. The treated mathematical modelling of the presented phenomena is based on utilizing the continuous linear signal transfer theory and the extended modem communication and information theory for the spectral domain of spatial frequencies, especially. The presented equations are acceptable for an analysis and optimal synthesis of digital electronic imaging systems fidfilling the proposed signal transfer model. These systems give conventionally a better information efficiency and image quality in comparison with the older analog imaging systems.
