Image capturing apparatus

An image capturing apparatus comprising:

• an 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, wherein said acceleration sensor is arranged so as to make the first measurement axis and the second measurement axis symmetric to each other about an axis in a vertical direction and cause the first measurement axis and the second measurement axis to intersect the imaging optical axis when the image capturing apparatus is placed in a landscape orientation;
• a calculation unit that reads out simultaneously the outputs of the first measurement axis and the second measurement axis of said acceleration sensor at a predetermined time interval, and that calculates an arc tangent of a ratio of an acceleration due to gravity measured by the first measurement axis and an acceleration due to gravity measured by the second measurement axis at the predetermined time interval, thereby obtaining an inclination degree of the image capturing apparatus around an imaging optical axis;
• a display control unit configured to display an inclination amount of the image capturing apparatus as a level indicator, the inclination amount being equal to the arc tangent of a ratio of the accelerations;
• and
• a display configured to display an indicator bar and a scales of the level indicator to represent the inclination degree of the image capturing apparatus,
• wherein the display control unit changes the relative position between the indicator bar and the scales of the level indicator based on the inclination amount.
