To provide an image rotation adapter capable of, by using an existing camera and an existing image capturing lens, giving a special effect to a video image captured by the camera. An image rotation adaptor (16) mounted between an image capturing lens (14) and a television camera (12) includes: a first prism (42) configured to reflect object light five times and to invert an object image; a second prism (44) configured to reflect the object light emitted from the first prism (42) five times and to return the object image to the original state; and a relay optical system configured to re-form a temporarily formed object image on the light receiving surface of each of image pickup devices (54R, 54G, 54B) of the television camera (12). The second prism (44) is held by a rotatably supported prism holding frame (60), so that the object image formed on the light receiving surface of each of the image pickup devices (54R, 54G, 54B) is rotated by rotating the second prism (44). |
