PROBLEM TO BE SOLVED: To provide a picture coincidence-judging device capable of improving a processing speed. SOLUTION: A picture converting part 14 performs low resolution processing for bit-shifting the RGB picture data to a low-order side. A grouping processing part 18 performs the processing of dividing picture data given low resolution processing to each group (partial picture) having the same color and generates grouped data regulated by the three attributes of a color (RGB component), an area and a shape in accordance with each divided group. A graphing processing part 22 performs graphing processing for obtaining a combining state between the respective groups to generate graphed data. An evaluation processing part 26 judges the coincidence/non-coincidence of the picture by investigating the connecting state based on the three elements of the color, an area ratio and the shape by using the graphed data obtained in accordance with each of the two picture data to be comparing objects.
