PROBLEM TO BE SOLVED: To provide an impact light-emitting point detection device capable of accurately measuring a detection of the impact light-emitting point only with image data not requiring any distance data.SOLUTION: This invention relates to a device 3 for correcting a canon in reference to an impact position information by detecting an impact light-emitting point generated from an impact of bullet from photographed images. As a pre-processing for performing a detection of impact light-emitting from the image, influence of canon flame is eliminated and a precise detection of impact light-emitting point is carried out by performing an impact light-emitting point start judgment 17 under application of judgment 23 of diminishing canon flame in reference to a brightness average value for every frame of image and impact light-emitting start judgment 17 under application of standard deviation for every frame of image. |
