Abstract
In an imaging device including a mechanical image blurring correction and a sensitivity image blurring reduction, a subject-shake amount is calculated based on a motion vector size acquired during a through image process display. Usage percentages of the mechanical image blurring correction and a sensitivity image blurring reduction are sequentially set based on the calculated subject-shake amount. When shooting a still-image, still-image data is recorded after blurring reduction is performed on the still-image data by the mechanical image blurring correction and a sensitivity image blurring reduction, based on the most recently set usage percentages.
Claims29
An imaging device comprising:
- an image pickup section for imaging a subject and outputting image data;
- an image blurring correction section for correcting image blurring;
- an image blurring reduction section for reducing image blurring;
- a detection section for detecting image shake based on image data to which image blurring correction has been performed by the image blurring correction section;
- and
- a control section for controlling an amount of image blurring reduction performed by the image blurring reduction section, based on the image shake detected by the detection section.
An imaging device comprising:
- an image pickup section for imaging a subject and outputting image data;
- an image blurring correction section for correcting image blurring;
- an image blurring reduction section for reducing image blurring;
- a detection section for detecting subject distance;
- and
- a control section for controlling an amount of the image blurring reduction performed by the image blurring reduction section based on the subject distance detected by the detection section.
An imaging device comprising:
- an image pickup section for imaging a subject and outputting image data;
- an image blurring correction section for correcting image blurring;
- an image blurring reduction section for reducing image blurring;
- a setting section for setting a percentage of an amount of image blurring correction performed by the image blurring correction section and an amount of image blurring reduction performed by the image blurring reduction section;
- and
- a control section for making the image blurring correction section perform the image blurring correction and the image blurring reduction section perform the image blurring reduction, depending on the percentage set by the setting section.
An image blurring reduction method which is used by an imaging device including an image pickup section for imaging a subject and outputting image data, an image blurring correction section for correcting image blurring, and an image blurring reduction section for reducing image blurring, the image blurring reduction method comprising:
- a detection step of detecting image shake based on image data to which image blurring correction has been performed by the image blurring correction section;
- and
- a control step of controlling an amount of image blurring reduction performed by the image blurring reduction section based on the image shake detected at the detection step.
A computer program product for an imaging device including
- an image pickup section for imaging a subject and outputting image data, stored on a computer-readable medium, comprising:
- an image blurring correction process for correcting image blurring;
- an image blurring reduction process for reducing image blurring;
- a detection process for detecting image shake based on image data to which image blurring correction has been performed by the image blurring correction process;
- and
- a control process for controlling an amount of image blurring reduction performed by the image blurring reduction process, based on the image shake detected by the detection process.
