IMAGE-BLUR CORRECTION APPARATUS, TILT CORRECTION APPARATUS, METHOD OF CONTROLLING IMAGE-BLUR CORRECTION APPARATUS, AND METHOD OF CONTROLLING TILT CORRECTION APPARATUS
First Claim
1. An image-blur correction apparatus comprising:
- a designation unit configured to designate a level of an effect of image-blur correction and a level of an effect of first tilt correction of an imaging apparatus having an optical axis as a rotary axis;
an electronic correction unit configured to execute at least one of the image-blur correction and the first tilt correction by changing an image clipping range set within an imaging screen; and
a control unit configured to vary a ratio of a correctable range of trapezoidal distortion caused by tilting of the image-blur correction apparatus and a ratio of a first tilt-correctable range in the electronic correction according to the level of the effect of the image-blur correction and the level of the effect of the first tilt correction,wherein each unit is implemented by one or more processors, circuitry, or a combination thereof.

Abstract
A tilt correction apparatus includes a manipulation unit configured to designate a level of an effect of first tilt correction of an imaging apparatus having an optical axis as a rotary axis and a level of an effect of second tilt correction of the imaging apparatus having an axis orthogonal to the optical axis as a rotary axis, an electronic correction unit configured to execute at least one of the first tilt correction and the second tilt correction by moving an image clipping range set within an imaging screen, and a calculation unit configured to vary a ratio of a first tilt-correctable range and a ratio of a second tilt-correctable range from the electronic correction unit according to the level of the effect of the first tilt correction and the level of the effect of the second tilt correction.
