The problem of the relation of the iconic system's recognition probability (under known a priori statistics) with the system parameters and the necessary image scale is considered. It is shown that the resolution as a system quality criterion results in the essential errors. The new expression to correlate the recognition probability, the image scale, and the system parameters for the aerial photographic system by using as a criterion the information estimate C1 is proposed. The information estimate C1 is connected with the signal-to-noise ratio of the system. The original signal model is given. The distinctions between the estimate C1 and the information capacity C0 are shown. On the basis of the proposed method the application program package for the numerical optimization of the air photographic systems and their modules is realized. The mathematical model of the system implemented in the package takes into account the conditions of the real aerial shooting. The package can be used to optimize the parameters of the black-and-white photographic films and their photochemical treatment.
