Abstract
An electronic timepiece includes a display, a driver that drives the display, and a CPU that controls the driver. The CPU inverts, in a time less than or equal to a reference inversion time and at an inversion timing of a constant polarity inversion cycle, a polarity of a voltage to be applied to the display. Additionally, the CPU outputs image data to the driver at an image update timing of a cycle that is synchronized with the inversion cycle and that is equivalent to a reference cycle equal to the inversion cycle multiplied by an inverse of an integer. The image update timing is a time when a reference adjustment time elapses after a timing of the reference cycle. The reference adjustment time is less than a time of the reference cycle and greater than or equal to the reference inversion time.
