摘要:
A method and system of placing information on a photosensitive film having a magnetic layer provides for the storage of image data on the magnetic layer of the film in a manner which permits the image data to be easily recalled and displayed on a monitor. The system and method can utilize an enabled Advance Photo System camera which is capable of reading digital data magnetically encoded on film. The information can be compressed and written onto the film at the time of film processing. The enabled Advanced Photo System camera reads this information and is connectable to a host computer for permitting the transfer of the information from the camera to the computer. At the computer, the digital image data can be decompressed and viewed by a user for downstream manipulation of the images.

A single-use camera comprises a light-tight film casing and a film cassette located inside the casing. The film cassette includes a rotatable film spool with an end portion engageable to rotate the spool, and an active light lock with an end portion engageable to rotate the light lock open to permit film movement out of and into the cassette interior and closed to prevent ambient light from entering the cassette interior. The casing has separate weakened areas covering the end portion of the spool and the end portion of the light lock which can be entirely pierced to make respective perforations in the casing to permit individual access to the end portions to engage them for rotating the spool and for rotating the light lock closed and, simultaneously, to destroy the casing to prevent it from being reused.

A virtually transparent magnetic layer is included as an additional layer in a photographic film strip. Information exchange between various users of the film such as, for example, the film manufacturer, the camera user, the dealer and photofinisher, is facilitated by plural longitudinal magnetic tracks on the film that begin and end within individual frames. Each track is dedicated to the writing and reading of a predetermined set of parameters relating to the corresponding frame, for easy access by a particular one of the various users. Each user has the capability to read and/or write informaton in self-identifying data fields in the corresponding tracks.

A series scene indication is magnetically recorded adjacent appropriate frames in a strip of film by an autowind camera whenever it is in rapidfire mode. The camera includes a magnetic head positioned to record data in a magnetic layer of the film strip as the strip is transported by a take-up reel, and a processor which intelligently senses when the camera is in a rapidfire mode and instructs recording electronics to energize the magnetic head in order to record the series scene indication on the film strip.

An optical system comprising two plastic elements is suitable for use in very low cost, wideangle cameras having curved image surfaces. This system has low distortion across a curved field angle of 65 degrees or more.

In a film cassette, a film spool is rotatable inside a cassette shell in an unwinding direction to thrust a leader section of a filmstrip coiled about the spool from within a light-tight film passageway to the exterior of the shell and in a winding direction to return the leader to the interior of the shell. A unidirectional arresting device is movable into engagement with the spool to prevent rotation of the spool in only the winding direction. The filmstrip includes an inclined edge for moving the arresting device out of engagement with the spool responsive to thrusting the leader substantially to the exterior of the shell, to allow the spool to be rotated in the winding direction in order to return the leader to the interior of the shell, and for permitting the arresting device to move into engagement with the spool responsive to return of the leader to within the passageway, to prevent the spool from being rotated further in the winding direction to thereby retain the leader in the passageway.

A motorized disk film camera which is of simple, compact and inexpensive construction and yet provides one-button operation to expose the film and actuate a motor which disengages the film and cocks the shutter, then advances the locates the film. The camera requires no separate operation to initialize a cartridge when it is loaded into the camera. The shutter actuation does not require a long button stroke and the motor drive and control is simple and inexpensive.

A disk cartridge includes a protective envelope located within the cartridge housing for enclosing a magnetic disk. the envelope prevents dust and other contaminants from reaching the disk surfaces and provides a rigid interior enclosure for the flexible disk, which supplements the housing in protecting the flexible disk from being folded or otherwise damaged. Loading the cartridge in a disk recording and/or playback apparatus actuates means in the cartridge for rotating the envelope within the housing to position a head-access opening and a backer-access opening in the envelope substantially in registration with corresponding openings in the housing. Removal of the cartridge from the apparatus causes the envelope to be rotated to position the envelope across the respective openings in the housing.
