An image capturing device, comprising: an image capturing means (7a, A2) configured to photograph images of a first group, the first group comprising a plurality of images in which a subject is photographed for a first exposure time, respectively, the plurality of images being consecutive in time, images of a second group, the second group comprising a plurality of images in which the subject is photographed for a second exposure time, respectively, the plurality of images being consecutive in time, wherein the second exposure time is shorter than the first exposure time, and a third image in which a subject is photographed with a higher sensitivity than the sensitivity with which either the images of the first group are photographed or the images of the second group are photographed, wherein the image capturing means (7a, A10) is configured to photograph the images of the first group, the images of the second group, and the third image in response to one photographing instruction; a hand-blur determination means (7a, A10) configured to determine whether blur caused by hand movement of the image capturing device has occurred during photographing of the images of the first group by way of the image capturing means; an image-blur determination means (7a, A8) configured to determine whether image blur of a subject has occurred during photographing of the images of the first group by way of the image capturing means due to the subject itself moving, a selection means (7a, A11, A12) configured to select, if it is determined by the image-blur determination means that no image blur has occurred, either an image of the first group or an image that is acquired from the images of the second group, in accordance with a determination result by the hand-blur determination means, and to select the third image if it is determined by the image-blur determination means that image blur has occurred, an image processing means (7a, 7h, A12) for synthesizing the images of the second group to generate a new image, wherein the image that is acquired from the images of the second group is the new image, and a storage means configured to store the image selected by the selection means on a storage medium. an image capturing means (7a, A2) configured to photograph images of a first group, the first group comprising a plurality of images in which a subject is photographed for a first exposure time, respectively, the plurality of images being consecutive in time, images of a second group, the second group comprising a plurality of images in which the subject is photographed for a second exposure time, respectively, the plurality of images being consecutive in time, wherein the second exposure time is shorter than the first exposure time, and a third image in which a subject is photographed with a higher sensitivity than the sensitivity with which either the images of the first group are photographed or the images of the second group are photographed, wherein the image capturing means (7a, A10) is configured to photograph the images of the first group, the images of the second group, and the third image in response to one photographing instruction;
