Abstract:
1. A photographic apparatus comprising: a movable platform that has an imager that captures an optical image through a taking lens, and is movable and rotatable on an xy plane perpendicular to an optical axis of the taking lens; a controller that calculates an inclination angle of said photographic apparatus, which is formed by rotation of said photographic apparatus around the optical axis, as measured with respect to a level plane perpendicular to the direction of gravitational force, and performs a controlled movement of said movable platform for an inclination correction based on the inclination angle; and an acceleration sensor that detects a first gravitational component, a second gravitational component, and a third gravitational component, the first gravitational component being a horizontal component of gravitational acceleration in an x direction perpendicular to the optical axis, the second gravitational component being a vertical component of gravitational acceleration in a y direction perpendicular to the x direction and the optical axis, and the third gravitational component being an optical-axis direction component of gravitational acceleration in a z direction parallel to the optical axis, wherein said controller calculates an elevation/depression angle on the basis of the third gravitational component, and calculates the inclination angle on the basis of the elevation/depression angle and only one of the first gravitational component and the second gravitational component, the elevation/depression angle representing an angle at which the optical axis intersects the level plane.
