FIELD: radio engineering, communication.
SUBSTANCE: method of increase of resolution of video systems is offered which is based on the use of subpixel shift of a matrix image in neighbouring frames during information receiving, it is characterized by that even frames are taken with diagonal shift by half-pixel with reference to odd frames and the taken frames are saved then the sizes of these frames are increased by adding to their matrix structure of zero columns and lines and these increased frames are also saved, and then a sequence of output signals is formed by simultaneous or consecutive read-out of data of each increased odd and respective increased even frames. The received output signals are processed by means of three-dimensional interpolation time-space low-pass filter which is made with transparent area as an octahedron.
EFFECT: increase of resolution of video systems due to double increase of frame pixel size.
