A clock change method includes: converting the serial data synchronized to a first clock into parallel data; latching the serial-to-parallel converted data into a designated data storing circuit with a latch timing that occurs once in every a number of clock cycles of a second clock; and converting the latched parallel data into the serial data synchronized to the second clock, and wherein: each time a packet of serial data synchronized to the first clock is received, a timing adjustment is performed to adjust the latch timing so that the latch timing occurs a predetermined time after occurrence of a conversion timing for converting the serial data synchronized to the first clock into the parallel data.
