Abstract

A CPU measures a cycle of a vertical synchronization signal inputted from an IPP based on an oscillation frequency of an internal ceramic oscillator. The CPU corrects the timing of starting the control of an object to be controlled based on the measured cycle of the vertical synchronization signal when the timing of starting the control of the object to be controlled is to be decided based on the vertical synchronization signal as a reference.
