IMAGE CAPTURING APPARATUS AND IMAGE CAPTURING METHOD
First Claim
1. An image capturing apparatus that captures an image and corrects blurring of the captured image, said image capturing apparatus comprising:
- an image capturing unit configured to capture an image;
an output unit configured to output an image of a framing area, the framing area being a part of a spatial area of the image captured by said image capturing unit;
a movement detection unit configured to detect motion vectors in an outer area in the spatial area of the image captured by said image capturing unit, and derive a dispersion of the detected motion vectors as detection accuracy;
an area adjustment unit configured to adjust a size of the outer area so that the detection accuracy derived by said movement detection unit meets a predetermined threshold; and
a correction unit configured to correct blurring of the image outputted by said output unit, by moving the framing area according to the motion vectors detected by said movement detection unit in the outer area of the size which has been adjusted by said area adjustment unit, irrespective of a movement of an image in an inner area in the spatial area.

Abstract
To provide an image capturing apparatus that detects a camera movement accurately and corrects image blurring appropriately. An image capturing apparatus (200) includes: an image sensor unit (103) that captures and outputs an input image (105); an output unit (121) that outputs an image of a framing area (160) of the input image (105); a motion vector calculation unit (106) and a stationary object detection unit (201) that detect motion vectors in an outer-frame area (161) of the input image (105) and derive detection accuracy; an outer-frame area adjustment unit (205) that adjusts the outer-frame area (161) in size so that the detection accuracy meets an outer-frame area change threshold (tr); and a camera movement calculation unit (113) and a framing area modification unit (115) that move the framing area (160) according to motion vectors in the adjusted outer-frame area (161), irrespective of motion vectors in the other area.
