Abstract:
A video camera, having a body which supports a Depth of Field adapter and contains an image recording device comprises imaging optics having a disk shaped ground glass for rendering visible a real image; a rotatable post having a first end coupled to the ground glass at its center and a second end coupled to the body of the Depth of Field adapter; and a motor coupled to rotate the rotatable post to urge the ground glass to rotate, and where the Depth of Field adapter comprises first and second tubes which, when aligned, form a front tube of the Depth of Field adapter; a coupling ring coupled to align and join the first tube with the second tube; and a support member coupled to the first and second tubes to position the first and second tubes to be at the front of the optical path of the camera.
