To provide a code conversion circuit which is reduced in the effort of design and also is suppressed in the increase of circuit scale, and also to provide a counter.

Pseudo gray codes in which each numeric value from a numeric value zero to a numeric value 13 is expressed by 5 bits, and all humming distances between the adjacent numeric values and between the numeric value 13 and the numeric value zero are 1, are converted into binary codes by a first code conversion circuit 12, counted up by an addition circuit 13, converted into pseudo gray codes corresponding to the counted-up binary codes by a second code conversion circuit 14, and stored in a first register 11.
