A synchronization apparatus synchronizing an operation of a first processing unit pre-processing an input signal and an operation of a second processing unit post-processing on signal from the first processing unit, may include: a counting unit that operates with a period sufficiently shorter than a period of a first reference signal governing timing of pre-processing in the first processing unit, and outputting, when counting a set target count value, a second reference signal governing timing of post-processing in the second processing unit; a phase control unit that generates a control value controlling a phase difference of the second reference signal with respect to the first reference signal in accordance with a count value when the first reference signal is input; and a filter unit that filters the generated control value so as to determine the target count value to be set in the counting unit. |
