Photographic apparatus
View Patent ↗A photographic apparatus comprises a movable platform and a controller. The movable platform has an imager and is movable and rotatable on an xy plane perpendicular. The controller calculates an inclination angle of the photographic apparatus, and performs a controlled movement of the movable platform for an inclination correction based on the inclination angle. The controller calculates a first position of the movable platform before the inclination correction. The controller calculates a second position of the movable platform after the inclination correction. The controller determines whether the movable platform should be moved to a third position before moving from the first position to the second position in the inclination correction, on the basis of a positional relationship between the first position and the second position. The third position is a position of the movable platform in an imaging operation by the imager without the inclination correction.
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 said taking lens; and
a controller that calculates an inclination angle of said photographic apparatus, which is formed by rotation of said photographic apparatus around said 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 said inclination angle;
said controller calculating a first position of said movable platform before said inclination correction;
said controller calculating a second position of said movable platform after said inclination correction;
said controller determining whether said movable platform should be moved to a third position before moving from said first position to said second position in said inclination correction, on the basis of a positional relationship between said first position and said second position;
said third position being a position of said movable platform in an imaging operation by said imager without said inclination correction;
said second position being a position of said movable platform in an imaging operation by said imager with said inclination correction, and being a position whereto said movable platform is rotated without translation from said third position in accordance to said inclination angle.
2. The photographic apparatus according to claim 1 , wherein said controller moves said movable platform to said third position before moving from said first position to said second position, when a rotation angle of said movable platform for moving said movable platform from said first position to said second position is larger than a threshold angle.
3. The photographic apparatus according to claim 1 , said controller performs said inclination correction on the basis of said inclination angle calculated before a shutter release switch is set to the ON state, performs a first controlled movement of said movable platform to said third position during a mirror-up operation after said shutter release switch is set to the ON state, and performs a second controlled movement of said movable platform to said second position after completion of said mirror-up operation or after completion of said first controlled movement.
