FIELD: information technologies.
SUBSTANCE: method and device for smoke detection records multiple images; one of multiple images is defined as analysed image, if one of multiple images is identified as having moving object; chroma variation of analysed image is analysed; at least edge smear or flicker frequency of analysed image is analysed; at least one of analysed results obtained by analysis steps is compared with relevant specified specific characteristic; and determine that moving object is smoke if at least one of analysed results is in compliance with corresponding specified specific character.
EFFECT: high accuracy of smoke detection.
