Abstract
A control section 11 moves an imaging lens 1 based on a detection signal from an angular velocity detection section 6 so as to correct image blurring which occurs in captured image data obtained through imaging performed by an imaging element 3. The control section 11 calculates a first motion vector between first captured image data, which is obtained through imaging performed by the imaging element 3, and second captured image data which is obtained subsequent to the first captured image data and in which image blurring is corrected. The control section 11 performs an offset correction for reducing an offset signal included in the detection signal of the angular velocity detection section 6, based on the first motion vector.
Claims15
A camera shaking correction device comprising:
- an angular velocity detection section that detects an angular velocity;
- an image blurring correction section that corrects image blurring, which occurs in captured image data obtained through imaging performed by an imaging element, by moving at least one of the imaging element, which captures an image of a subject through an optical imaging system, and the optical imaging system, based on a detection signal of the angular velocity detection section;
- a first motion vector calculation section that calculates a first motion vector between first captured image data, which is obtained through imaging performed by the imaging element, and second captured image data which is obtained subsequent to the first captured image data and in which image blurring is corrected by the image blurring correction section;
- an offset correction section that performs offset correction for reducing an offset signal included in the detection signal of the angular velocity detection section, based on the first motion vector;
- and
- a filtering section that performs filtering for attenuating a low frequency component of the detection signal of the angular velocity detection section,
- wherein the image blurring correction section corrects image blurring in accordance with an amount of correction of image blurring which is generated based on the filtered detection signal, and
- wherein the offset correction section performs the offset correction by further using a difference between an amount of correction of image blurring, which is generated based on the unfiltered detection signal, and the amount of correction of image blurring which is generated based on the filtered detection signal.
