1. A spatter counting method performed by a portable terminal device provided with a processor, an image capturing device, and a display device, the method comprising:
an image capturing step of in which the image capturing device captures a moving image of an area including spatters generated during welding;
an image processing step in which the processor performs binarization processing of the moving image;
a counting step in which the processor counts a number of the spatters captured in each still image constituting the moving image captured in the image capturing step after the binarization processing, each spatter being an area having a black and white gradation equal to or higher than a first threshold value, being composed of adjacent pixels having a black and white gradation equal to or higher than the first threshold value, and having a size equal to or less than a second threshold value; and
a display control step in which the display device displays the moving image, the number of the spatters counted in each still image in the counting step in association with each other, and a statistical value of the number of the spatters,
wherein the number of the spatters in each still image is displayed in the form of a graph.
