Abstract
A frame opening of a camera image area is maskable in both horizontal and vertical directions using L shaped masks, each L shaped mask able to mask adjacent sides of the frame, and diagonally oppositely arranged. The masks are driven by a disk member rotatable by the user, and are linked together to mask the top and bottom and/or left and right sides of the frame. The rotating disk may unidirectionally mask the vertical or horizontal portions of the frame or all four sides of the frame.
