Description: It is grounded, that for the increase of degree of compression of images without the additional losses of their quality on basis two izofoty aperture of encoding it is required to carry out compact presentation of official information. Encoding of official data, based on separate treatment of arrays, consisting of sizes of maximal and minimum levels of dynamic ranges is expounded. Encoding of arrays of official data is conducted in raznostnom space of range levels. The estimation of degree of compression of images is conducted on basis two izofota aperture of encoding and encoding of arrays of official data.
Keywords: aperture presentation, compression of official information
