PPROBLEM TO BE SOLVED: To judge the selection state of choices in a system for encircling a symbol on a slip without performing any registering operation to store the image of the predetermined area of a slip as a standard image or without being conscious of the shape of a circle encircling the symbol. PSOLUTION: A CPU 101 cuts out an area to be judged where a predetermined symbol is included from image data, and retrieves and counts line segments in each band-shaped area obtained by dividing the area cut out into band-shaped areas in a predetermined direction. When the band-shaped areas where the counted number of segments is not less than a first specific value continue, the CPU 101 counts the number of the continuous band-shaped areas, and compares the maximum value of the counted number of the band-shaped areas with a threshold based on the resolution of the image data, and decides whether the symbol is encircled by a predetermined graphic.
