PROBLEM TO BE SOLVED: To detect information relating to a photographing condition by a module different from an imaging part, and photograph an image of high image quality when a subject is a subject of low luminance.SOLUTION: An electronic camera 10 has a semi-transmissive mirror 20 arranged between an imaging lens 13 and a first imaging part 21. In the semi-transmissive mirror 20, a first rotation shaft 40 is arranged orthogonally to a photographing optical axis 16 almost at a center of both side surfaces 39 and a second rotation shaft 41 is arranged orthogonally to the photographing optical axis 16 at one end of both side surfaces 39. In accordance with a photographing mode, a central processing unit (CPU) rotates the semi-transmissive mirror 20 centering around the first rotation shaft 40 between a first rotation position where subject light travelling to the first imaging part 21 is branched to light travelling to an optical finder part 23 and a second rotation position where the subject light is branched to light travelling to a second imaging part 22 arranged on an opposite side of the optical finder part 23 across the photographing optical axis 16. Further, when the subject is a subject of the low luminance, the semi-transmissive mirror 20 is rotated centering around the rotation shaft 41 from the first rotation position to a retreat position where a surface 20a having an anti-reflection film provided is retreated from the photographing optical axis 16. |
