Abstract
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.
