Design of method of renewal of bit planes of transforms times are expounded on basis unequal weight of the position decoding. This method is based on implementation of transformations: determining the amount and scopes of code words, expended on the compressed presentation of bit planes component of transform; renewal of arrays of lengths of binary cerouss is conducted for an account unequal weight of the position decoding; renewal of bit presentation of transform on the basis of the known sizes and set direction of round of bit planes; renewal of binary matrices of signs is a component of transforms. It allows to provide reproduction of images with the set authenticity at: minimizations of influence of errors, brought in on the stage of compression, I.e. the size of index of error after renewal of image must not exceed the size of index of error for the stage of compact presentation; use of official information which are directly formed on the stage of compression.
