PROBLEM TO BE SOLVED: To solve the problem in which conventionally, there has been a case where an image photographed at an automatically determined rotation angle of a polarizing filter is against a user's intention.SOLUTION: According to the present invention, a camera has: a filter that is rotatable around a rotary axis including an optical axis of an optical lens and parallel with the optical axis; photographing means for photographing an image through the optical lens and the polarizing filter; detection means for detecting a rotation angle with respect to a reference angle of the polarizing filter; and control means for photographing, by the photographing means, a plurality of images as rotating the polarizing filter, acquiring, by the detection means, the rotation angle when each image is photographed, and storing information on the rotation angle when respective images are photographed in association with image data on each photographed image in a storage medium. |
