In practice often there is a problem of increase of detail of the optical plotting. As a rule, it is reached at the expense of augmentation of their permission. In the works published earlier existing methods of augmentation of the permission are considered and their features and lacks are shown. The mean of increase of the permission of the optical plotting by scanning by system mobile opaque шторок, located over a surface of a template photodetector, space of the plotting and formations of new values of pixels on the basis of algorithm of difference processing is offered, and also the assessment of its working capacity on time expenses is made. The mean essence is concluded in restriction in certain sequence of a part of an incidenting optical stream on each photosensitive surface of elements of a template photodetector. The mean realizability is provided with uniform sensitivity as template elements, and their photosensitive surface. It is achievable by means of pre-award calibration of elements of the permission which results are considered at algorithm realisation. With use of criterion of Neumann-Pirsona calculation of time of accumulation of the photodetector necessary for realisation of demanded likelihood characteristics of detection at preset values of a bridging of an optical stream is carried out. The analysis of the received results shows that the plotting received by means of the offered mean c by the account of time of accu-mulation at each stage of a bridging of a photosensitive surface of elements of a template possesses the raised clearness of perception in comparison both with initial, and with received with attraction of program methods. Thus, the mean of increase of the permission of the plotting by scanning by system mobile opaque шторок, located over a surface template ФПр, spaces of the plotting and formation of new values of pixels on the basis of algorithm of difference processing is con-sidered. The assessment of working capacity of a mean on time expenses testifies to existence of certain restrictions on reception of the plotting of the raised permission of moving objects owing to sharp augmentation of time at their formation in process of augmentation of quotient of the permission at conservation of demanded likelihood characteristics of detection.
