Patent ID: 8792010

Claim:
An image capturing apparatus comprising: a first acceleration sensor that measures accelerations applied to the image capturing apparatus in a first measurement axis direction and a second measurement axis direction, the first measurement axis direction and the second measurement axis direction intersecting each other; a second acceleration sensor which measures accelerations applied to the image capturing apparatus in a third measurement axis direction and a fourth measurement axis direction, the third measurement axis direction and the fourth measurement axis direction intersecting each other; and a calculation unit that calculates an inclination of the image capturing apparatus around an imaging optical axis based on an arc tangent of a ratio of an output of said first acceleration sensor in the first measurement axis direction and an output of said first acceleration sensor in the second measurement axis direction and calculates an inclination of the image capturing apparatus around an axis that intersects the imaging optical axis based on an arc tangent of a ratio of an output of said second acceleration sensor in the third measurement axis direction and an output of said second acceleration sensor in the fourth measurement axis direction, wherein said calculation unit calculates the inclination around the axis that intersects the imaging optical axis by shifting the output of said second acceleration sensor in the third measurement axis direction and the output of said second acceleration sensor in the fourth measurement axis direction by a predetermined offset amount when the inclination of the image capturing apparatus around the image optical axis is a predetermined inclination.
