Claim One:
1. An image processing device comprising: a processor; and a memory which stores a plurality of instructions, which when executed by the processor, cause the processor to execute, acquiring an image that includes a marker that includes a plurality of first color regions and a plurality of second color regions, of which a color is different from a color of the first color regions, the plurality of first color regions being opposed to each other and the plurality of second color regions being opposed to each other; extracting the first color regions or the second color regions from the image; reducing the first color regions or the second color regions until a first degree of similarity between a shape of the first color regions or the second color regions, the first color regions or the second color regions being extracted, and a predetermined elliptical shape satisfies a predetermined first threshold value; and calculating a second degree of similarity between the first color regions or the second color regions, the first color regions or the second color regions satisfying the first threshold value, and a predetermined butterfly shape.
