FIELD: information technologies. ^ SUBSTANCE: method is proposed to control coding with internal prediction used in coding with internal prediction, having multiple modes of prediction and dimensions of prediction unit, at the same time each of prediction mode and dimension of prediction unit may switch, when coding is performed. Method includes stage of calculation of monotony extent index, which indicates extent of monotony of target area for coding; stage of determination of dimension of prediction unit used in coding with internal prediction of target area, in compliance with calculated index of monotony extent; and stage of selection of prediction mode used in coding with internal prediction of target area for determination of prediction unit dimension. ^ EFFECT: increased efficiency of coding with internal prediction for reduction of calculation costs. ^ 7 cl, 14 dwg |
