A fire detection device luminance data over a time period longer than a repetition period of movement of a flame, to generate resampled data, and a device that calculates an average value of N (natural number equal to or larger than 2) items of the resampled data, and determines that the input image is an image of a flame, by comparing a count of sampled data items larger than the average value, or a count of sampled data items smaller than the average value, with a predetermined value.
