You can count.

Then, the similarity determining unit 119 sets '8', which is the number of component values of 1 included in the arithmetic matrix of '4' x '4' corresponding to the'★' among the plurality of special characters, to '4'. By dividing by '8', which is the number of component values of 1 included in the input matrix 220 of x '4', '1' can be calculated as a quotient corresponding to'★', and corresponds to the'★' The quotient '1' may be determined as a similarity between the input matrix 220 of '4' x '4' and the reference matrix of '4' x '4' with respect to the'★'.

In addition, the similarity determining unit 119 sets '4', which is the number of component values of 1 included in the arithmetic matrix of '4' x '4' corresponding to the'■' among the plurality of special characters, to '4'.
