Abstract
Apparatus in a simple low cost camera for encoding predetermined pseudo-formats of exposed image frames on film of the type having a magnetic layer thereon in which there is a data track prerecorded on the film. A user-operable selector means on the camera is set to establish the format of an image frame to be exposed on the film. In response to the selector means, a magnetic erasure means is activated by an erasure encodement signal generating means to selectively erase predetermined portions of a segment of the data track associated with a corresponding pseudo-format exposed image frame. Means are provided for inhibiting activation of the erasure means when the film is advanced in the camera in a direction opposite to the direction associated with frame-by-frame advance during the picture-taking process.
