Abstract RU 2607259 C2

FIELD: information technologies.

SUBSTANCE: invention relates to encoding and decoding of images. Disclosed is method of images encoding for image encoding per coding unit, wherein method comprises: application of frequency conversion to conversion unit brightness data and colour data in coding unit, including predetermined units, each corresponds to one or more of conversion units (stage S501); and encoding brightness data and colour data, to which frequency conversion is applied to generate bits stream, in which brightness data and colour data are grouped per predetermined unit (step S502).

EFFECT: technical result is efficient images encoding and decoding per unit.
