An image capturing apparatus in which an image of a subject formed by lenses and a low pass filter of a photographic optical system is provided to an imaging device unit that supplies a corresponding signal to an A/D converter that in turn provides an output to an image processing unit. A blur-detecting device with a blur detecting part and a blur detecting unit detect blur that is compensated by a blur compensating unit with a blur-compensation driving unit. A system controller computes a displacement amount for blur compensation by the blur-compensation driving unit driving the blur compensating unit based on an output of the blur detecting device. A memory group is included for calibrating a conversion coefficient used by the system controller in calculating the displacement amount.

Image capturing apparatus with blur compensation

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.
