Abstract
A stabilization control apparatus that supports a plurality of shooting modes including a first shooting mode and a second shooting mode. The first and second shooting mode have different diagonal-line lengths of an available area of an image sensor. The stabilization control apparatus sets different reference positions of the image sensor depending on which of the first and second shooting modes is set. The reference position is the center of an area within which the image sensor is moved for image stabilization.
Claims16
A stabilization control apparatus comprising at least one processor, wherein the at least one processor functions as:
- a mode setting unit configured to set one of a plurality of shooting modes including a first shooting mode and a second shooting mode, wherein a diagonal-line length of an available area of an image sensor in the first shooting mode is a first value, wherein the image sensor photoelectrically converts a subject image formed by an imaging optical system and outputs an image signal, and the diagonal-line length of the available area is a second value smaller than the first value in the second shooting mode;
- a reference position setting unit configured to set a reference position of the image sensor when a correction amount for image stabilization is 0;
- and
- a control unit configured to move the image sensor from the reference position in a plane perpendicular to an optical axis of the imaging optical system, based on a shake,
- wherein the reference position set by the reference position setting unit when the first shooting mode is set by the mode setting unit differs from the reference position set by the reference position setting unit when the second shooting mode is set by the mode setting unit, and
- wherein the reference position setting unit sets the reference position so that a distance between a position of the optical axis and the reference position is shorter when the diagonal-line length of the available area of the image sensor is the first value than when the diagonal-line length is the second value.
An image capture apparatus comprising:
- an image sensor that photoelectrically converts a subject image formed by an imaging optical system and outputs an image signal;
- at least one processor functions as:
- a mode setting unit configured to set one of a plurality of shooting modes including a first shooting mode and a second shooting mode, wherein a diagonal-line length of an available area of the image sensor is a first value in the first shooting mode, and the diagonal-line length of the available area is a second value smaller than the first value in the second shooting mode;
- a reference position setting unit configured to set a reference position of the image sensor when a correction amount for image stabilization is 0;
- a control unit configured to move the image sensor from the reference position in a plane perpendicular to an optical axis of the imaging optical system, based on a shake,
- wherein the reference position set by the reference position setting unit when the first shooting mode is set by the mode setting unit differs from the reference position set by the reference position setting unit when the second shooting mode is set by the mode setting unit;
- and
- an imaging control unit configured to control image capture by the image sensor,
- wherein the imaging control unit controls image capture by the image sensor based on the shooting mode set by the mode setting unit,
- wherein the reference position setting unit sets the reference position so that a distance between a position of the optical axis and the reference position is shorter when the diagonal-line length of the available area of the image sensor is the first value than when the diagonal-line length is the second value.
An image capture apparatus comprising at least one processor or circuit, wherein the at least one processor functions as:
- an acquisition unit configured to acquire information representing a size of an available area of an image sensor that photoelectrically converts a subject image formed by an imaging optical system and outputs an image signal;
- a setting unit configured to set a reference position based on the information representing the size of the available area of the image sensor acquired by the acquisition unit, the reference position being a position of the image sensor when a correction amount for image stabilization is 0;
- and
- a control unit configured to move the image sensor from the reference position based on a shake, in a plane perpendicular to an optical axis of the imaging optical system,
- wherein the setting unit sets the reference position so that a distance between a position of the optical axis and the reference position is shorter when a diagonal-line length of the available area of the image sensor is a first value than when the diagonal-line length is a second value.
A stabilization control method comprising:
- setting one of a plurality of shooting modes including a first shooting mode and a second shooting mode, in the first shooting mode, a diagonal-line length of an available area of an image sensor that photoelectrically converts a subject image formed by an imaging optical system and outputs an image signal, is a first value, in the second shooting mode, the diagonal-line length of the available area of the image sensor is a second value that is smaller than the first value;
- setting a reference position of the image sensor when a correction amount for image stabilization is 0;
- and
- controlling to move the image sensor from the reference position in a plane perpendicular to an optical axis of the imaging optical system, based on a shake,
