Abstract
Frequency-divided clock generating section generates a frequency-divided clock having a predetermined driving frequency by dividing a base clock having a base frequency based on a set frequency-division ratio. Division-ratio calculating section calculates a real number ratio of the driving frequency relative to the base frequency and sets a rounded frequency-division ratio by rounding the real number ratio as the frequency-division ratio while calculating a rounding error. Accumulated error calculating section adds the rounding error to an accumulated error when frequency-divided clock generating section generates a frequency-divided pulse which is a one cycle of frequency-divided clock. Division-ratio correcting section uses, as the frequency-division ratio, the rounded frequency-division ratio if the accumulated error does not exceed a threshold value, and a value obtained by correcting the rounded frequency-division ratio based on the threshold value and subtracts the threshold value from the accumulated error if the accumulated error exceeds a threshold value.
