Claim 0:
1. A welding condition setting assistance device that assists setting of a welding condition of arc welding when the arc welding is performed by generating an arc between a workpiece and an electrode by applying a voltage between the workpiece and the electrode, the device comprising
an image processing unit that performs:
a spatter detection step of detecting a spatter from each of a plurality of input images constituting a moving image of the workpiece, the spatter being an area included in the input image, the area including a plurality of continuous pixels each having a pixel value exceeding a predetermined threshold, the pixel value indicating a brightness, the moving image being generated by capturing the workpiece during the arc welding;
a background bright spot identification step of identifying, as a background bright spot, a position collocated in the plurality of input images in the moving image, the position being a position at which a number of times of the detection in the spatter detection step for the plurality of input images is equal to or more than a predetermined reference number of times; and
a spatter number identification step of identifying, for one of the plurality of input images, a number of spatters excluding spatters each corresponding to the background bright spot identified by the background bright spot identification step among the spatters detected by the spatter detection processing.
