Abstract
A blur correction device includes: a sensor; a mechanical blur correction device; an electronic blur correction circuit that corrects the blurring by performing image processing on an image obtained through imaging of the imaging apparatus; and a supplementary blur correction circuit that, in a case where the mechanical blur correction device and the electronic blur correction circuit are shared and operated at a predetermined ratio during the exposure, corrects the blurring by applying, to the image, a filter that removes noise which appears in the image.
Claims13
A blur correction device comprising:
- a sensor that detects an amount of blurring of an imaging apparatus;
- a mechanical blur correction device that corrects blurring by moving an optical element included in the imaging apparatus based on the amount of blurring;
- an electronic blur correction circuit that corrects the blurring by performing image processing on an image obtained through imaging of the imaging apparatus;
- and
- a supplementary blur correction circuit that, in a case where the mechanical blur correction device and the electronic blur correction circuit are shared and operated at a predetermined ratio during the exposure, corrects the blurring by applying, to the image, a filter that removes noise which appears in the image,
- wherein the predetermined ration is a ratio indicating which percentage of an amount to correct the blurring is allocated to the mechanical blur correction device and the electronic blur correction circuit, and
- wherein the filter is determined depending on the predetermined ratio.
A non-transitory computer-readable storage medium storing a program executable by a computer to perform processing comprising:
- mechanical blur correction processing of correcting blurring by moving an optical element included in an imaging apparatus based on an amount of blurring detected by a sensor that detects the amount of blurring of the imaging apparatus;
- electronic blur correction processing of correcting the blurring by performing image processing on an image obtained through imaging of the imaging apparatus;
- and
- supplementary blur correction processing of correcting, in a case where the mechanical blur correction processing and the electronic blur correction processing are shared and operated at a predetermined ratio during the exposure, the blurring by applying, to the image, a filter that removes noise which appears in the image,
- wherein the predetermined ration is a ratio indicating which percentage of an amount to correct the blurring is allocated to the mechanical blur correction device and the electronic blur correction circuit, and
- wherein the filter is determined depending on the predetermined ratio.
