The paper proposes a block diagram of digital aperture correction for aerospace research, which allows increasing the signal-to-noise ratio by 1.5 times. The model of the nonlinear proof-reader on the computer is developed and its characteristics are defined. It is established that application of aperture correction raises resolution of TV of system on 20 %. The analysis of characteristics of visual perception with reference to correction of clearness of TV of images is made. It is established that by increase in an
average level of brightness without transfer of small values of the video signal corresponding to fine details of the image it is possible to improve its quality
