FIELD: physics, processing of images.
SUBSTANCE: for data processing of video signal for the block of the image with coefficients of two basic images for a prediction of this block of the image use implicit weighing of basic images, thus the decoder includes the module of implicit weight coefficients of basic images for definition of the weight coefficient corresponding to each coefficient of the basic image; The coder includes the module of appointment of implicit weight coefficient of the basic image for definition of weight coefficient for each coefficient of the basic image, and the decoding method includes reception of coefficients of basic images with data which correspond to the image block, definition of implicit weight coefficient in reply to a standing of the block of the image concerning the basic images specified by each coefficient of the basic image, extraction of the basic image for each coefficient, performance of neutralisation of a motion concerning the taken basic image and multiplication of basic images in which relation motion neutralisation is executed, on the corresponding size.
EFFECT: improvement of compressing of the video image.
