FIELD: video image processing.
SUBSTANCE: unit for pixel depth increasing is implemented with the possibility to scale colour pixel depth of video image frame, an area subdividing unit is implemented with the possibility to divide a video image frame producing areas of equal size for each colour and ensuring successive switching-over between areas and colours; at that, each conveyor is implemented with the possibility to delete false contours in two areas in four directions simultaneously, and an averaging unit is implemented with the possibility to calculate an average sum of data from outputs of four conveyors for each colour.
EFFECT: increase of image colour pixel depth along with deletion of false contours in real time.
