PROBLEM TO BE SOLVED: To switch a rotation angle of a half mirror to perform photographing.SOLUTION: A camera 100 includes: a half mirror which is attached to be rotatable with a rotation axis as a center and separates incident light from a lens into transmitted light and reflected light; control means for controlling the rotation angle of the half mirror; a first sensor which receives the incident light from the lens when the rotation angle of the half mirror is set to a first angle with which the half mirror is saved from the optical axis by the control means and receives the transmitted light of the half mirror when the rotation angle of the half mirror is set to a second or a third angle where the half mirror is arranged on the optical axis; a second sensor for receiving the reflected light of the half mirror when the rotation angle of the half mirror is set to the second angle; and a third sensor for receiving the reflected light of the half mirror when the rotation angle of the half mirror is set to the third angle. |
