FIELD: physics.
SUBSTANCE: method of grey image conversion colour is offered that implies that the original grey image presented elements array is divided on n frequency channels. Low-frequency and n-1 high-frequency channels are isolated and correlation of elements within high-frequency channels is calculated that is used a basis to calculate weight factors of elements within high-frequency channels. Each frequency channel is given with colour, and output image is created by element-specific sums of colour of each frequency channel assuming element weight factors within high-frequency channels. At synthesis of output image, at least, in one n-1 high-frequency channel part of weight factors are nulled and/or smoothed.
EFFECT: expansion of image processing possibilities.
