Digital camera, composition correction device, and composition correction method
First Claim
1. A digital camera comprising:
- first captured image obtaining means for acquiring a first captured image by capturing an image of a subject at predetermined angle of view;
second captured image obtaining means for acquiring a second captured image by means of capturing an image of a subject identical with the subject while at least one of the image capturing angle of view and an attitude of the camera is changed as compared with its counterpart used for capturing the first captured image;
attitude detection means for detecting the attitude of the camera during image-capture operation;
rotation processing means for rotating the first captured image in order to make an image of the subject in the first captured image stand in an erect position, on the basis of the attitude detected at the time of capture of the first captured image; and
compensation means for compensating for missing portions where portions of the image are absent in a predetermined image recording range due to rotation of the first captured image, on the basis of the second captured image wherein the first captured image obtaining means and the second captured image obtaining means are two image capture means which are independently provided in one camera and capable of simultaneously acquiring images of a single subject at different angles of view; and
the first captured image and the second captured image we images which are simultaneously captured by the two image capture means.

Abstract
When composition of a first captured image having a tilted subject image is corrected, the first image is rotated such that the subject image stands in an erect position, according to the attitude of the camera achieved during capture of the first image. Images corresponding to missing portions, which arise in the image area for recording due to rotation, are extracted from a second captured image as compensation images. The second image is obtained by capturing an image of the same subject as that captured by the first image, at the different angle of view and attitude of the camera. An image obtained by enlarging the compensation images extracted from the second image according to the angle of view employed for capturing the first image is synthesized with the rotated first image, to thus make the subject image stand in an erect position and to obtain a corrected image without involving a decreased number of pixels.
