Abstract
Dependences of the efficiency while recognizing noisy static and moving test objects on the duration of their presentation are experimentally studied. Investigation is conducted for different observation conditions. It is found that with increasing duration of observing the dynamic images of test objects in the presence of a white noise the efficiency decreases at first. It is underlined that upon achieving the minimal value that takes approximately 120 ms it grows and then upon achieving the maximal value taking approximately 400 ms it decreases monotonically. Mathematical modeling of the processes of accumulation of the image signal component in the visual memory is fulfilled.
