1. A leak source specification assistance device, comprising a hardware processor that performs processing, based on a movement of a first pixel that is one of pixels constituting an image including a leaking fluid region, to determine a second pixel that is one of the pixels constituting the image and is a movement source pixel of the first pixel, and repeats the processing with the second pixel newly set as the first pixel to determine a final movement source pixel,
wherein the hardware processor repeats the processing on each of a plurality of the pixels constituting the image to determine the final movement source pixel for each of the plurality of pixels;
wherein the hardware processor determines that two or more of the pixels located within a predetermined angle range with respect to an axis indicating a direction opposite to a direction of the movement of the first pixel are candidates for the second pixel, and determines the second pixel from among the candidates.
