Method and apparatus for image blur correction
First Claim
1. An image-capturing apparatus comprising:
- a first image pickup element which picks up an actual image of a subject;
a second image pickup element which detects a displacement and has sensitivity that is higher than that of the first image pickup element;
an image pickup unit which picks up an image of the subject by driving the first image pickup element and the second image pickup element simultaneously;
a displacement detecting unit which computes an amount of displacement between images due to a camera shake using image data obtained from the second image pickup element when the image of the subject is picked up by the image pickup unit; and
a position correcting unit which corrects a position of image data obtained from the first image pickup element, based on the amount of displacement computed by the displacement detecting unit.

Abstract
An image-capturing apparatus includes a first image pickup element which picks up an actual image of a subject, a second image pickup element which detects a displacement and has sensitivity that is higher than that of the first image pickup element, an image pickup unit for picking up an image of the subject by driving the first image pickup element and the second image pickup element simultaneously, a displacement detecting unit for computing an amount of displacement between images due to a camera shake using image data obtained from the second image pickup element when the image of the subject is picked up by the image pickup unit, and a position correcting unit for correcting a position of image data obtained from the first image pickup element, based on the amount of displacement computed by the displacement detecting unit.

9. An image processing method applied to an image-capturing apparatus including a first image pickup element which picks up an actual image of a subject and a second image pickup element which detects a displacement and has sensitivity that is higher than that of the first image pickup element, comprising:
-
picking up an image of the subject by driving the first image pickup element and the second image pickup element simultaneously;
computing an amount of displacement between images due to a camera shake using image data obtained from the second image pickup element when the image of the subject is picked up; and
correcting a position of image data obtained from the first image pickup element, based on the amount of displacement computed.

10. A program product recorded in a computer-readable recording medium and executed by a computer for controlling an image-capturing apparatus including a first image pickup element which picks up an actual image of a subject and a second image pickup element which detects a displacement and has sensitivity that is higher than that of the first image pickup element, comprising:
-
causing the computer to perform a first function of picking up an image of the subject by driving the first image pickup element and the second image pickup element simultaneously;
causing the computer to perform a second function of computing an amount of displacement between images due to a camera shake using image data obtained from the second image pickup element when the image of the subject is picked up by the first function; and
causing the computer to perform a third function of correcting a position of image data obtained from the first image pickup element, based on the amount of displacement computed by the second function.
