Abstract
To present a digital camera capable of operating a piezoelectric element without particularly preparing any boosting circuit inside the digital camera. In a digital camera for acquiring image data by taking a subject image, an imaging device for taking the subject image, and a piezoelectric element for displacing the imaging device are provided, and a main capacitor for stroboscope emission is used as the power supply source for the piezoelectric element.
