Summary:A determining method for fire, a determining system for fire using the same and a determining device for fire using the same are provided. The determining method comprised the following steps. First, a plurality of to-be- analyzed frames is captured in a plurality of time points. Then, whether the to-be- analyzed frames have suspected fire images is determined. Then, a profile size of each suspected fire image is obtained according to an analysis reference point of each suspected fire image. Then, a specific value between the profile sizes of the suspected fire image captured in adjacent two times is calculated. Then, a variation frequency of the specific values is calculated. Then, whether the variation frequency conforms to a fire frequency range is determined. Then, if the variation frequency conforms to the fire frequency range, the suspected fire images are determined to be the image of a real fire.
