FIELD: imaging technology.

SUBSTANCE: group of inventions relates to image encoding and decoding technologies in which the image is divided into blocks and prediction is performed. A device for encoding images is proposed. The device is designed with the ability to encode in units of standard blocks of in-block copying. The device contains a block for obtaining block vector candidates, a selector made with the possibility of selecting the selected block vector from the block vector candidates, a block for correcting the reference position, a prediction block. In this case, the block for correcting reference position is made with the ability to set a fixed number of standard blocks of in-block copying subjected to the encoding process immediately before the standard block of in-block copying, including the target block, as a reference area and to set the standard block of in-block copying before the reference area and the standard block of in-block copying, including the target block, as the invalid reference area regardless of whether the encoding process is completed.

EFFECT: increase in the efficiency of encoding/decoding images.
