Image capturing apparatus

摘要

An image capturing apparatus includes an acceleration sensor having a first measurement axis and a second measurement axis that intersect each other, and arranged on a plane that intersects the imaging optical axis of the image capturing apparatus while inclining the first and second measurement axes by about 45° in the vertical direction, and a calculation unit that calculates the arc tangent of the ratio of the detection result of an acceleration due to gravity by the first measurement axis and the detection result of an acceleration due to gravity by the second measurement axis, thereby obtaining the inclination degree of the image capturing apparatus in the rolling direction.

1. 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.
