Smoke detecting method and device

Abstract

A smoke detecting method and device are provided. The smoke detecting method and device capture a plurality of images; determine one of the plurality of images as an analyzable image when the one of the plurality of images is identified to have a moving object; analyze a chrominance variation of the analyzable image; analyze at least one of an edge blur and a flickering frequency of the analyzable image; compare at least one of analyzed results from the analyzing steps with a corresponding predetermined feature; and determine the moving object is a smoke when at least one of the analyzed results conforms to the corresponding predetermined feature.
