A media width detecting system is adapted to measure an absolute width of media without the need for human intervention or without the need for media to be referenced against a known location. The media width detecting system includes a measuring pattern that is provided across a media path for media. The measuring pattern can be in the form of, for example, a bar code pattern. The system further includes a reader that is provided relative to the measuring pattern so as to read the width of the measuring pattern. When media traverses the measuring pattern, a portion of the measuring pattern, for example, a subset of the bars of the bar code pattern, is covered by the media. The reader would then be adapted to determined a width of the measuring based on the covered portion of the media pattern in relation to the uncovered portion or uncovered bars.

Media width detecting system for an imaging apparatus

A photofinishing system for automatically processing image and associated image data pursuant to customer output requests. The system includes an order manager operative to receive and control processing of the output requests and at least one source of image related data corresponding to the output request. An input interface receives the image related data from the source and converts the data to a digital data stream. A memory is included for storing the digital data stream. The system further includes a data parser disposed in communication with the memory to extract selected data streams according to the order manager and to reduce the data into respective image files having respective groups of data fields. An output module is responsive to the order manager and is operative to produce a photofinished output organized with respect to the data fields.

Photofinishing system and method for automated advanced services

A photoprocessing apparatus for sensing type of photoprocessing consumable and method of assembling the apparatus. The invention includes a photographic printing and developing apparatus (10) adapted to allow the apparatus to sense types of supplied consumable photosensitive paper and photoprocessing chemicals and method for assembling the consumable paper and chemicals for sensing. An electrically programmable read/write memory contained in a transponder (54) is integrally attached to the consumable paper or chemicals package. The transponder (54) is capable of receiving a first, RF frequency electromagnetic field and deriving power and address information from the first frequency, then generating a second RF frequency electromagnetic field in response, where the second electromagnetic field is characteristic of the data stored in memory. A transceiver (50) is disposed within the photographic printing and developing apparatus (10) with antenna (56) and support components for polling each transponder (54). As instructed by a control logic processor (14), transceiver (50) can both read manufacturing data from the transponder (54) about the consumable paper or chemical and write usage and processing data to the transponder (54) for storage in memory.

Photoprocessing apparatus for sensing type of photoprocessing consumable

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 information in self-identifying data fields in the corresponding tracks.

Film information exchange system using dedicated magnetic tracks on film

The reliability of data transfer between stages of photographic filmstrip use and processing is enhanced by magnetically recording a limited data set repetitively along a wide track in a frame of the filmstrip. Plural laterally offset magnetic read heads monitor the data in the magnetic track and provide output data signals on parallel independently operating channels. The data content of the output data signals is examined to determine whether the data of an individual data signal contains corruption error. The combined linear and parallel redundancy of the system tends to ensure successful data transfer despite a less than perfect head-to-film interface and other data corrupting influences.

A magnetic layer is included as an additional layer in a photographic film. Information exchange between various uses of the film, such as the camera user, the dealer and photofinisher, is facilitated by recording data in dedicated frame-limited longitudinal track(s) in said film. All data is recorded on the film using a self-clocking three-part code in order to provide automatic data synchronization between the various users without requiring film transport at the same speed or even a uniform speed when reading and writing data. Three-part encoded binary characters uniquely representing start and stop sentinels respectively, are recorded at the beginning and end of the track respectively and facilitate automatic detection of the direction of film strip transport.

A virtually transparent magnetic layer is included as an additional layer in a color negative film. Information exchange between various users of the film--such as (for example) the film manufacturer, the camera user, the dealer and photofinisher--is carried via plural longitudinal magnetic tracks on the film that begin and end in individual frames. Each track is dedicated to the writing and reading of a predetermined set of parameters related to the corresponding frame. The photofinisher-dedicated tracts fill the exposed image area of each frame. The camera-dedicated tracks lie along the edges of the film between the film perforations, the perforations being widely spaced for this purpose. All data is recorded on the film using a novel self-clocking code which is completely self-clocking, in order to provide automatic data synchronization between the various users without requiring that any of them to transport the film at the same speed or even at a uniform speed when reading and writing. A start sentinel character and stop sentinel character, each having a predetermined self-clocking encoded binary bit sequence, are placed at the beginning and end of each track respectively, and facilitate automatic detection of film transport direction.

An electrical circuit suitable for encoding binary information, in accordance with a novel modulation method, is provided. The encoder circuit includes: a clock driver; an n-phase counter driven by the clock driver for producing a succession of event-cells, wherein each event-cell is demarcated by a pair of similar, unique clock transitions; first logic circuitry for generating a first transitional event in a first event-cell in response to a first information; and second logic circuitry for generating a second transitional event in a second event-cell in response to a second information, the first transitional event and the second transitional event differing by the number of transitions occurring per event-cell. A specific, preferred encoder circuit embodiment is set forth.

Self clocking binary information encoder

Electrical circuits suitable for encoding a binary data stream into a tri-bit code format. The circuits are particularly valuable for situations where the encoding or information transfer rate is dependent on unpredicable and variable transfer rate velocities and accelerations. The circuits provide 'self-clocking', which, in turn, permit velocity insensitive encoding.

Three-part encoder circuit

Novel electrical circuits suitable for decoding an encoded binary data stream. The electrical circuits include digital circuitry, and are preferably employed to decode magnetic information or optical information. The information has been encoded in a three-part code format according to a method which features self-clocking, velocity insensitive encoding and decoding. The novel electrical circuits decode the encoded information, and preserve the self-clocking velocity insensitive features of the novel method.
