CROSS-REFERENCE TO RELATED APPLICATIONS  
       [0001]    This is a continuation-in-part of U.S. application Ser. No. 09/800,157 filed Mar. 6, 2001, which is a continuation of U.S. application Ser. No. 09/213,517 filed Dec. 17, 1998 by Joseph Manico et al., entitled System and Method for Communication of Digital Images Generated from Photographic Film. 
     
    
     
       FIELD OF THE INVENTION  
         [0002]    This invention relates to the field of photography, and in particular to communication of digital photographic images to a remote destination after processing of photographic film and for communicating with a customer of a file processing service for picture previewing and selection.  
         BACKGROUND OF THE INVENTION  
         [0003]    In a traditional photofinishing operation, a customer brings in his/her film to be processed and printed. Several steps are necessarily taken by the customer to actually receive his/her finished prints where some of these steps are tedious, time consuming, and otherwise inconvenient. With the advent of networked processors it has become possible to enter a customer&#39;s home via the networked computer to permit a degree of interfacing with a film processing service provider. One such provider is Eastman Kodak Company which offers a service called PhotoNet. A customer provides the photoprocessing service with a source of developed pictures that are scanned and stored for access via the Internet. Access to the customer&#39;s file may be selectively granted to others having a networked computer, for example, relatives and friends for viewing and downloading.  
           [0004]    Currently available photographic 240IX film (Advanced Photo System) allows the recording of auxiliary information on a magnetic layer on the film. It has been suggested to provide a system that permits the customer to record his/her electronic address on the film such that a film processor could almost instantly make available for viewing a digitized version of the images that have been developed from the customer&#39;s film, and to additionally permit the customer to communicate print ordering instructions to the film processor which prints can be either picked up at a later convenient time or delivered by conventional means.  
           [0005]    A problem with these approaches is that if a photographer does not have a personal Internet account or e-mail address, this type of service is not available to her. Another problem with this suggested approach is that there is no way for a customer to proactively determine the status of their order. The first possibility that they have to communicate with the system is when they receive an e-mail notice that they have pictures waiting. Another problem is that traditional e-mail is not a secure communication process. Anyone who sees the e-mail message to the customer can gain access to the images. It is well known that e-mail addresses are prone to transcription errors resulting in delivery to an unintended party or not delivered at all. A still further problem is that if a persons e-mail address changes after submitting the order and before receiving the message from the service provider, access to the images may be frustrated. Basically, there is no guarantee that e-mail will reach its intended recipient.  
           [0006]    There is a need therefore for an improved system and method of distributing digital images generated from photographic film.  
         SUMMARY OF THE INVENTION  
         [0007]    The shortcomings noted above are overcome according to the present invention by providing a photographic system includes a photographic film having a film ID number thereon; a receipt provided with the photographic film, the receipt being imprinted with a uniform resource locator for acquiring an image on the film via the Internet, and an associated password; a scanner for scanning the film after processing to generate a digital image; means for associating the film ID number with the digital image; a digital image storage device for storing the digital image; a web server connected to the digital image storage device, having means for accessing the digital image using the uniform resource locator; a database accessible by the web server having stored therein the film ID number and the associated password; and wherein the means for accessing the digital image is password protected and accessible by use of the password.  
         ADVANTAGES  
         [0008]    The present invention is advantageous in that it provides a system that is more secure than the current systems. It allows photographers without their own Internet account, or e-mail address to use the service at a public facility, such as a public library, publicly accessible terminal, or computer kiosk, or use of a friend&#39;s or associate&#39;s computer. The URL and Password and database to link film ID with passwords are assigned by the manufacturer of the film. The scanner/code reader automatically assigns URL&#39;s and uses the manufacturer provided database to verify passwords. There is also a security benefit of having the film manufacturer provide the user the only hardcopy of the URL address and password.

     DETAILED DESCRIPTION OF THE INVENTION  
       [0016]    Referring to FIG. 1, one-time use camera (OTUC)  10  useful with the present invention is shown. The OTUC  10  includes a shutter release button  20 , a viewfinder  30 , lens  40 , electronic flash  50 , electronic flash “on” switch  60 , and film advance mechanism  65  (not shown). Referring to FIG. 2, according to a preferred embodiment of the present invention, the OTUC  10  contains a film cartridge  70 , imprinted with a human readable unique film ID number  90 , a corresponding machine readable film ID number  100  and an unexposed film strip  80 . The film cartridge can be a 35 mm film cartridge or an 240IX Advanced Photo System (Advantix) type film cartridge. The machine readable film ID number  100  can be an optically readable bar code on the film cartridge  70  as shown. In addition an optical code can be recorded on the film, or in the case of the Advantix type film, magnetically recorded on a magnetic recording layer on the film.  
         [0017]    According to an alternative embodiment of the present invention, the film cassette  70  is provided with the aforementioned features for use with the user&#39;s traditional, reloadable camera.  
         [0018]    According to a further alternative embodiment, the unique ID number is stored in a non-volatile memory in an integrated circuit chip that is attached to the film cassette, film, or prepaid mailer. The integrated circuit chip can be provided with external contacts that enable the chip to be read by a machine, in the same way as the chips used in smart credit cards attached to an antenna in a radio frequency identification transponder. The radio frequency identification transponder can be addressed by a radio communication unit without direct contact.  
         [0019]    Referring to FIG. 3, the system of the present invention employs a pre-paid processing envelope (mailer)  110  that is sold in combination with the OTUC or roll of film. The mailer  110  has a tear off tab  120 , imprinted with a unique Uniform Resource Location (URL) address  130  and a password  140 . The URL, but not the password may also be printed at a location on the mailer other than on the tear off tab. The film ID number is part of, or a reference to the URL address that will be used to acquire the images via the Internet as described below. Prepaid mailer  110  is also imprinted with a mailing address  150  of a film processing laboratory. For security purposes, the password is included only on the tear off receipt and in a database provided to the film processing laboratory by the film manufacturer. The prepaid mailer  110  may also have an area  155  (not shown) for the user to write an e-mail address if e-mail notification or e-mail delivery of the resulting images is also desired.  
         [0020]    Alternatively, a receipt in the form of a ticket, card, or removable label imprinted with the URL and password information may be provided with the film or OTUC instead of a pre-paid mailer. The receipt may include an additional portion containing the URL, but not the password, that can be included or affixed to a standard photofinishing envelope. Alternatively, two receipts may be provided; one with the password and one without. The receipt without the password can be provided with an adhesive back for affixing to the photofinishing envelope. The password may be obscured, for example by a covering of opaque wax such as used on instant lottery tickets, a folded over portion of the receipt, or a removable covering to provide extra security to the user. This would be used in conjunction with an affiliated retailer that would forward the film to a photofinishing lab that provides the service or the retailer may perform the service in house if the retailer is an affiliated photofinisher. This is the current procedure in the photographic industry for providing specialty photofinishing services. Photofinishing labs that offer “ColorWatch” photo service guarantee to the user that Kodak manufactured paper and chemistry, and Kodak approved photofinishing procedures are observed. For the user to obtain “ColorWatch” photofinishing he/she must locate a retailer that provides this service.  
         [0021]    [0021]FIG. 4 shows a processed film strip  160  and FIG. 5 shows a close up view of a section  170  of processed film strip  160 . As shown in FIG. 5, the processed film strip includes the human readable unique ID code  180  and a machine readable bar-coded unique film ID code  190 . For each image  200 , the film may also include an eye readable film frame number  210 , and a machine readable frame number  220 . Alternatively, the machine readable unique ID code  190  may be magnetically encoded on a transparent magnetic layer on the film strip.  
         [0022]    Referring to FIG. 6, the steps employed in using the system of the present invention will be described. First, in step  240 , the user purchases an OTUC loaded with film or a 35 mm or 240IX film cassette encoded with a unique ID code for use in a conventional camera; a pre-paid mailer with a tear off receipt imprinted with a unique URL address that includes the code on the film and a password associated with the unique code. Next, in step  250 , the user takes photographs with the OTUC or conventional camera in the normal manner. When the exposures are complete at step  260 , the user removes the tear off receipt, inserts the OTUC or film roll into the pre-paid mailer and mails it to the photofinisher. Alternatively, the user may go directly to a retail affiliated photofinishing provider that offers this service and request the service. At step  270  the photofinisher reads the code from the mailer and logs the code into the photofinisher&#39;s order processing system. Optionally, the photofinisher records the photographer&#39;s home address from the mailer. At step  280  the photofinisher reads the unique code printed on the film cartridge and records the code number at the film spooler or film processor prep station and communicates the code number to the photofinisher&#39;s order processing system. At step  290  the film is processed and scanned by the photofinisher and the unique code number is read by the scanner and sent to the photofinisher&#39;s order processing station.  
         [0023]    The code on the mailer is used to link the user&#39;s name and address to the film ID number. The film and mailer are transferred to an “order bag” used to transport the mailer, film, and resulting print and/or other image products through the photofinishing lab. The code on the cassette is used to link the “twin check” number assigned to the film to the photofinishing order bag. The code on the film strip is used once the film has been processed by the scanner to automatically assign the URL. With magnetically encoded film, the film does not have to be processed for the magnetic code to be readable.  
         [0024]    At step  300  the magnetically encoded and/or bar-coded film ID number is read and the scanned images are automatically stored in the photofinisher&#39;s computer in a password protected URL access account with the film ID number designation. The digital images are accessible via the Internet, and the password associated with the URL is obtained from a secure database provided by the film manufacturer.  
         [0025]    At step  310  a few days (or hours if a retail provider with in house processing, scanning, and digital transmission capabilities is used) may have elapsed before the user uses his computer and Internet browser to access his/her images from any computer having access to the world wide web using the unique URL and the security code that was provided on the tear off tab. At step  320  the images are sent to the user&#39;s computer and the user views the images. At step  330  using applets provided by the photofinisher, the user may now download, manipulate, store and/or print images using any viewing or printing equipment available at the viewing site. At step  340  the user may optionally submit a credit card number and purchase additional prints or image products and have them sent to any address indicated by the user.  
         [0026]    As shown in FIG. 7, the system architecture of the present invention also includes a photofinisher  350  to process the film delivered  400  to the photofinisher  350 , scan the processed images to generate digital images, read the film ID code from the mailer, the film cartridge, or from the processed film, and associate the film ID code with the digital images. The system also includes an Internet service provider  440  that manages a web server  450 , and includes an image storage file  470  and a database  480  containing film ID codes and associated passwords retrievable with the unique URL. The web service provider may also provide resources  460  via Java (or equivalent) applications, such as “KIA&#39;s Power Goo”, Adobe Photoshop, a Cartoon Algorithm, a Coloring Book Algorithm, Zoom, Crop, Rotate, Email, Album Page, Post Card, etc. These resources are not down-loadable and work only with the images located in the image storage file  470 .  
         [0027]    The photofinishing center  350  includes an order entry station  360  for reading the ID code from the mailer  110  or the film cartridge  70  and inputting any customer instructions prior to film development. The photofinishing center  350  includes a film processor  370  wherein the film is developed in the known manner. Several of the stations are provided with a network connection  410 ,  420  to the centralized service provider  440 . If the film contains a magnetic stripe with the unique ID code, the developed film from the film processor  370  is forwarded to a magnetic stripe reader  380  which reads the unique ID from the processed film strip. After reading the unique ID code, the developed film is forwarded to a photo imaging workstation (PIW)  390  for example one of the several PhotoCD PIWs manufactured by Eastman Kodak Company for writing PhotoCD discs and making index prints. The PIW  390  is used to scan the developed film strip to generate digital images and to transform the digital images into a hierarchical digital format. The digital images are transferred  430  to an image storage  470 . As part of that process a digital index file of low resolution digital prints is formed representing all of the scanned images appearing on the developed filmstrip. U.S. Pat. No. 5,184,227 issued Feb. 2, 1993 to Foley discloses a system that scans a film strip and forms a digital index print which contains a plurality of images corresponding to the images on the film strip. The digital index print at that point may be forwarded to a photographic printer (not shown) for hard copy generation. U.S. Pat. No. 5,400,152 issued Mar. 21, 1995 to Manico et al. discloses a similar system for quickly scanning a film strip, digitizing the images scanned, and forming a digital index print file that is optically printed as a low resolution representation of the images appearing on the film strip.  
         [0028]    If the film contains a magnetic stripe, the magnetic stripe reader  380  senses the existence of a unique ID on a strip of film which indicates that the customer wants to preview the images on the film strip prior to having hard copy prints made. Upon sensing the unique ID code, the film strip is forwarded to the PIW  390  for scanning (conversion to a digital form). The digital file, representing the images on the film strip and including the digital index file, along with the associated unique ID code is forwarded to the central service provider  440  for storage in a large scale, long term image storage memory  470 . If the film processor  370  does not sense the unique ID code, either on the film itself, or on a magnetic layer on the film, the digital file is forwarded, in the normal manner, to the photographic printer (not shown) for the printing of hard copy prints.  
         [0029]    Upon receipt of the digital file, the service provider makes the file available at the URL address associated with the unique ID code under the protection of the password. The file can then be accessed by the customer from any terminal having access to the world wide web. The customer can access the communication channel  510  for example via public access terminals  550  such as may be found in a public library  540 , or other public building. Access is also available via customer-operated kiosks  520  having a CPU  530  placed at retail locations.  
         [0030]    If the customer has also provided an e-mail address on the mailer  110 , the service provider  440  may send an e-mail message to the customer on the world wide web communication channel  510  indicating that the images are ready for viewing. The customer, at a convenient time, can then access the communication channel  510  to view the digital file on the monitor of the customers home computer  500  located in customer&#39;s home  490 .  
         [0031]    The customer may electronically order prints of the digital images directly from any point of access  500 ,  520 ,  550  to the communication channel  510  using the appropriate software. The packaged order is then delivered to the address supplied by the customer using any convenient form of shipment. The customer may authorize anyone else to view the files and order prints merely by sharing the URL and the password.  
         [0032]    The invention has been described in detail with particular reference to certain preferred embodiments thereof, but it will be understood that variations and modifications can be effected within the spirit and scope of the invention.
