Network photograph service system

BACKGROUND OF THE INVENTION

Field of the Invention

0001The present invention relates to a network photograph service system according to the preamble of claim 1 and a method of ordering prints according to the preamble of claim 5.

Description of the Related Art

0002For providing a service related to a photograph to a customer, a network photograph service has been proposed which provides a variety of services such as an order of extra prints, attachment of a photograph image to an electronic mail message, and download of picture image data by installing a variety of equipment such as a scanner, a printer, and a server computer comprising a large capacity disc (hereinafter called an image server) in a major wholesale lab in order to enable a customer to save a picture he/she recorded in the image server and to access the image server via a network.

0003The advantage of the network photograph service is that a customer can order a print even when the customer is staying at home or in an office. However, in reality, not everything, such as depositing a film or receiving a print, can be carried out on a network, Therefore, it is usual to provide the service through a local camera shop or a minilab as an agency.

0004It would be desirable to ease remote storage management for the pictures stored at the server computer.

0005In accordance with the preamble of claim 1 and claim 5, <patcit id="pcit0001" dnum="GB2286944A"><text>GB-A-2 286 944</text></patcit> discloses a network photograph service system and a method of ordering prints, and remote storage management by means of a phone call.

0006It is also known from the prior art field of remote printing orders to inform the user about a completed print job by means of electronic mail messages (<patcit id="pcit0002" dnum="US5155842A"><text>USA-5,155,842</text></patcit>).

SUMMARY OF THE INVENTION

0007Based on consideration of the above problems, an object of the present invention is to provide a network photograph service system which can provide a prompt service to a customer without losing the advantage of a network photograph service system such as easier understanding where to access and collective data management.

0008A network photograph service system of the present invention comprises the features of claim 1.

0009"The order information" specifically means, for example, the processing number specifying what has been ordered (such as an extra print or a postcard generation), the image number identifying a picture, the size of the print, and the number of the print. The "instruction information" includes not only the order information but also information showing where digital image data can be obtained from (where the digital image data are stored) or the like. In this case, when the laboratory server which received the instruction information does not have the necessary image data, the server requests the center server or the image server of the laboratory specified as the server from which the image data are obtained transfer the digital image data. Alternatively, the image data necessary for printing may be included in the instruction information.

0010"The printing service" in this specification means not only services such as outputting an extra print or generation of a picture postcard as described above, but also all accompanying services carried out before the picture print reaches a customer. More specifically, the mailing or delivery service instead of a reception of a finished print over a counter, the service to inform a customer via electronic mail that a print is ready or that a storage period of digital image data in a laboratory is about to expire, the service to extend the storage period by receiving electronic mail from a customer, the service that a customer can select the laboratory at which to receive a print, the service that ordered pictures are arranged in an album, and the service that a print is mounted on a photograph mount in the case of a memorial picture, are all considered as the printing service, for example.

0011Therefore, "the instruction information" and "the order information" are meant to include all information necessary for the accompanying service such as how a print is received and the address or the electronic mail address of the recipient. Such information can obviously be used not only for reference but also for a variety of processing. In other words, with a printer for generating a mailing label connected to the laboratory server, processing such as an automatic mailing label print can be carried out by referring to the name and address of a recipient included in the instruction information, when "the instruction information" specifies mailing of a print.

0012In a service for generating a manipulated print such as a composite picture, a method using a template has been known. When such a service is provided, the center server may store a template enabling the template to be accessed on the network so that a customer can order a manipulated print using the template. When a manipulated printing service is requested by the order information, information regarding the template specified by the order information may be transferred to the laboratory server as a portion of the instruction information.

0013"Information regarding the template" herein referred to means either the template itself or information showing a suffix of the template or where the template is stored.

DESCRIPTION OF THE PREFERRED EMBODIMENT

0015Hereinafter, a network photograph service system of the present invention will be explained referring to the accompanying drawings. The form of a system in which equipment is concentrated in one wholesale lab, and its problems, will be explained first referring to <figref idref="f0008">Figure 8</figref>.

0016In the system shown in <figref idref="f0008">Figure 8</figref>, a customer 1 asks for first prints from an agency 13 (121). The first prints may be generated by the agency 13 itself or by a wholesale lab 14 following a request from the agency 13. In each case, a film (122) from the customer 1 is temporarily handed to the wholesale lab 14 (122). The wholesale lab 14 reads the film using a scanner 7 or the like, and stores pictures recorded on the film in an image server 15 as digital image data. If first prints have been ordered from the wholesale lab, the prints are generated by a printer 9 or the like, and delivered to the agency 13 (123), and then handed to the customer 1 via the agency 13 (124).

0017After the image server 15 has stored digital image data, the customer 1 can access the image server 15 via the Internet 5 (125), and order an extra print or the like looking at the stored picture image data on a display screen. In response to this order, the image server 15 generates a print using the printer 9 or the like, and hands the print to the customer 1 (127) by mail or via the agency (126).

0018As is obvious from the flow described above, the wholesale lab 14 should collect all films from customers of all agencies in this system. Therefore, it is possible that delivery of a print will be delayed due to a collection and/or delivery queue or a processing queue. Since the collection and delivery of the films and prints are carried out by hand, the date of delivery of the finished print may be delayed a couple of days due to the collection and/or delivery queue, depending on the number of collections and deliveries per day. In other words, in this system, it becomes easier to order an extra print or the like, but a prompt service is not necessarily guaranteed. Furthermore, if an agency carries out first printing, input processing needs to be carried out by both the agency and the wholesale lab, for example. Therefore, this system often causes inconvenience.

0019In the network photograph service system of the present invention, as shown in <figref idref="f0001">Figure 1</figref>, a customer 1, a service center 2 which receives an order, and a minilab 3 or a special laboratory 4 with special equipment can all communicate via a network. On this occasion, since the service center and the special laboratory need to communicate especially frequently, they use high speed lines so that they can handle more orders promptly.

0020In the embodiment shown in <figref idref="f0001">Figure 1</figref>, digital image data input is carried out by the minilab 3. When the customer orders first prints to the minilab 3, the minilab 3 reads a film using a scanner 7 and generates first prints using a printer 9. The digital image data read by the scanner 7 are stored in a laboratory server 8 after the generation of the first prints. On this occasion, low resolution image data which are the digital image data in a reduced resolution (hereinafter called a thumbnail image) are generated and transferred to a center server 12 in the service center 2. The laboratory server 8 stores not only the digital image data of the customer but also a template thereof.

0021The center server 12 in the service center 2 stores the thumbnail image transferred from each laboratory in correlation with the laboratory from which the image has been sent, while making the thumbnail image accessible on the network. On this occasion, the thumbnail image does not need a particularly high quality, since the customer uses the thumbnail image only to confirm the picture upon an order. In order to save disc space, it is more preferable if the thumbnail image has a smaller amount of data. In this embodiment, digital image data that the laboratory server 8 stores for outputting a print has 4 base pixels (approximately 1024 X 1792 pixels) which are necessary for outputting an L size print at 300 dpi, while the digital image data that the center server 12 stores for an access via the network has 1/4 base pixels (approximately 368 X 256 pixels). The center server 12 also stores a thumbnail of the template that the laboratory server 8 stores so that the customer can access the template via the network.

0022When the digital image data are made accessible, the customer only has to confirm his/her own pictures. In other words, he/she does not want others to see his/her pictures. Therefore, by an authentication using a password, each customer has only a limited access to data he/she can see. The password is determined by a customer when he/she orders first prints. Alternatively, the minilab determines the password by assigning an appropriate one.

0023As for the access to the center server, the above service is provided in the form of a web page if on the Internet, and the customer can access the center server using a browser such as Netscape Navigator. Alternatively, if the service is provided as another original communication service, dedicated software may be distributed to each customer. In each case, the customer 1 can request a printing service without going to the minilab 3 by carrying out a predetermined input on an order screen through confirmation of the thumbnail image of his/her picture stored in the center server or selection of a template via the network from his/her house or office, or through generation of order information in a predetermined format and transmission of the information via electronic mail.

0024On this occasion, the order information transmitted from the customer to the center server 12 is like the example shown in <figref idref="f0002">Figure 2</figref>. The order information contains information necessary for extra prints, such as the image number, the size, the number of extra prints, and how the finished prints are received. Furthermore, in an order of a manipulated print, the template number or the like is also included in the order information. Moreover, the content of the service which can be provided through the network includes not only the service accompanying the print output, but also all services related to the printing service. For example, when a storage period of digital image data in the laboratory 8 will expire in a few days but the customer has not decided the picture to order for an extra print, a request for an extended storage in this case can be considered as a part of the services related to printing.

0025A variety of data structures of the order information are also possible. For example, Microsoft Corp. has proposed structured storage technique by which several kinds of data in different nature are stored in a file in a hierarchy. The order information can be generated as an order file shown in <figref idref="f0003">Figure 3</figref> by using this technique.

0026The format of the order information may be defined depending on the service to be provided, and the format shown in <figref idref="f0002">Figures 2</figref> and <figref idref="f0003">3</figref> are mere examples.

0027When the center server 12 receives such order information, it assigns the laboratory for outputting the ordered print. For instance, <figref idref="f0004">Figure 4</figref> shows an example of the processing to assign the laboratory for outputting the ordered print in the case where the order information in <figref idref="f0002">Figure 2</figref> is used. In this example, it is judged whether or not the requested processing needs special equipment by referring to the data showing the processing number. If the processing requires the special equipment, the special laboratory 4 is selected as the laboratory to output the print, and instruction information in a predetermined format is generated and transferred to the laboratory server 8 in the special laboratory 4. On this occasion, the special laboratory 4 does not have digital image data to be printed. Therefore, the instruction information includes the information showing the laboratory which has the digital image data.

0028When processing which does not need the special equipment, such as an ordinary extra print, is requested, it is checked if the customer wants to receive the print over the counter or by mail or delivery, by referring to order information data showing how the print is received. In the case of mailing or delivery, if no more convenient to the customer no matter which laboratory outputs the print he/she has ordered. Therefore, the laboratory which is most effective for the system, that is, the laboratory which stores the high resolution image data for outputting the ordered print is selected.

0029When the customer wants to receive the print over the counter, the order information data showing the laboratory at which the print is received is referred to, and the laboratory is selected as the laboratory to output the print. When no laboratory is specified in the order information, the laboratory which stores the high resolution image data is selected. When the laboratory specified by the customer does not have the high resolution image data, the information showing where the high resolution image data are stored is included in the order information, as is the case where the special laboratory 4 is selected.

0030When the center server 12 transmits the order information to the laboratory selected as described above, it records the content of the order and calculates a data storage fee, a communication charge and the like to be paid to each laboratory by periodically summing up the amount of data transferred. In this manner, transactions between the center server 12 and each laboratory, or between the laboratories, are managed. This management is carried out in this manner, because each laboratory can gain an appropriate profit by printing or by storing digital image data of its customers. Such data are obviously used in a charge billing system to customers as well.

0031The laboratory server 8 which received the order information carries out the processing such as outputting an extra print according to the content of the order included in the order information, and hands the print to the customer or arranges mailing or the like. On this occasion, the hand-over to the customer or a mailing arrangement should be carried out by hand, as has been carried out conventionally. However, the laboratory server 8 can carry out processing to help such operations, for example, to print a mailing label automatically by referring to the order information data showing the recipient, and to notify the recipient of the print output finish by automatically sending him/her an electronic mail.

0032An example of such a service viewed from the flow of data is shown in <figref idref="f0005">Figure 5</figref>. Regarding the manipulated printing service using the template, data each managed by a personal computer 6 of the customer, the center server 12, and the laboratory server 8, in addition to the flow of the data, are shown in <figref idref="f0005">Figure 5</figref>.

0033As described above, the laboratory server 8 stores high resolution image data 21 of the customer's picture and high resolution template 23 thereof. The center server 12 stores a low resolution template 24 which corresponds to the high resolution template 23, because whenever a new template is generated in the laboratory, a low resolution template corresponding to the new template is also registered in the center server. Meanwhile, low resolution image data 22 corresponding to the high resolution image data 21 are also registered in the center server upon a request from the customer.

0034The customer refers to (and downloads upon necessity) the low resolution image data 22 and the low resolution template 24 disclosed on the center server 12 and composes them using the personal computer 6. However, the processing carried out at this stage, such as composition, aims to generate the order information, and the processed image obtained through the processing is used for confirmation only. The procedure of the processing carried out by the customer is recorded by the function of dedicated software installed in the personal computer 6. The procedure is taken in as a portion of the order information 20 when the order information is generated. The order information 20 also includes information showing.an image 22a and a template 24a specified and used by the customer.

0035The order information 20 is received by the center server 12, and the center server 12 transmits instruction information 25 to the laboratory selected by referring to the order information 20. At this time, the instruction information 25 includes the information showing the image 22a, the template 24a, and the processing procedure. The laboratory server 8, which receives the instruction information including such information, searches the hard disc for the high resolution template 23a corresponding to the template 24a and high resolution image data 21a corresponding to the image 22a, based on the information, and outputs the print after the processing following the processing procedure.

0036Such a service as described above can be implemented by the system configuration shown in <figref idref="f0006">Figure 6</figref>, for example.

0037The personal computer 6 of the customer who carries out the order generation processing will be explained first. A WWW browser 30 has been installed in the personal computer 6... The program which carries out the order generation processing is provided as a plug-in of the browser. Alternatively, the function which carries out only a portion of the order generation processing is provided as the plug-in, and the other functions may be installed as application software independent from the browser.

0038The example in <figref idref="f0006">Figure 6</figref> shows the case where functions for browsing and downloading the low resolution image data and template, as well as a function for uploading an order file are provided as the plug-in, while a processing application 31 for processing the image data and template which have been downloaded, and an order file generating module 32, are provided as application software.

0039In this example, in the processing application 31, if the size and the number of a print are specified as in the case of ordinary printing (the printing by a printer connected to a personal computer), an order file is automatically generated by the function of the order file generating module 32.

0040If the low resolution image data and template are provided by a medium 11, the WWW browser 30 is used for browsing the data stored in the medium 11 and also for copying data from the medium 11 to the hard disc of the personal computer 6.

0041The configuration of the center server 12 will be explained next. As described above, the center server 12 is a server computer comprising a large capacity hard disc and a variety of communication equipment. The server computer 12 is used for providing the order receiving service in the form of a web page.

0042A WWW application server 36 which communicates with the WWW browser 30 of the personal computer 6 accesses low resolution image data base 33 and low resolution template data base 34 in response to the customer's request, and obtains necessary data, then transfers the data to the personal computer 6. The access to the data bases 33 and 34 may be carried out by an original protocol. However, by using a protocol 35 which is used by each company in common, it becomes possible to use a data base in another company's system in the same manner as the data base in the center server of its own company. In other words, it is preferable that the access to the data base or the like is carried out by defining the common image accessing protocol 35 for a search, a transfer, and access right management of the templates and images.

0043The WWW application server 36 receives the order file 20 uploaded by the user, selects the laboratory server 8 which is best-suited for processing the order, and transfers the order file 20 as it is or after adding necessary instruction information thereto. In other words, an order file transmitting receiving protocol 37 in <figref idref="f0006">Figure 6</figref> is the protocol for assigning the laboratory for printing, in response to the order content. It is also preferable to use a common order file transmitting receiving protocol.

0044A program 42 which analyzes the order file 20 transferred from the center server 12 and a program 41 which carries out the processing and printing based on the instruction in the order file 20 are installed in the laboratory server 8. After analyzing the order file 20, if the access right to the image specified in the order file is denied (if the password necessary for the access is not included in the order file), no processing and printing are carried out. If the access right is confirmed, the above program obtains necessary data from high resolution image data base 40 and high resolution template data base 38, and outputs the manipulated print.

0045The configuration and the function of the network photograph service system of the present invention has been described above. Next, an example of how convenient the system is to use will be described with reference to <figref idref="f0007">Figure 7</figref>.

0046For example, assume the case where a customer records pictures with his/her friend who came from overseas, and first prints are then ordered from a minilab 3a nearby (101) . The first prints are immediately processed by the minilab 3a, and the film is returned to the customer when the prints are finished (102). Assume that the customer records other pictures with the same friend at the friend's house overseas. Conventionally, first prints of pictures recorded on a trip have been ordered after the trip. However, since every operation, except for printing a film, can be carried out via the network in the network photograph service system of the present invention, it is highly likely that this system has affiliated laboratories overseas. Therefore, even when first prints are ordered from a minilab 3b near the friend's house (103), and the prints are received there (104), an extra print can be ordered after the customer returns to his/her country.

0047After the customer returns, he/she accesses the center server 12 from the personal computer 6 at home and orders extra prints of these pictures (105). At this time, for example, among the pictures whose first prints were ordered from the minilab 3a, an extra print of a picture a is ordered for the customer while a picture b is for the friend, and among the pictures whose first prints were ordered from the minilab 3b, an extra print of a picture c is ordered for the customer.

0048As for the pictures for the customer, the minilab 3a is specified as the laboratory at which the prints are received. As for the picture for the friend, mailing may be specified as the method to receive the print. However, in the case of air mail, it takes more than one day for the print to reach the friend. On the other hand, if an order is carried out with the friend being specified as the recipient and the laboratory 3b as the laboratory at which the print is received, the print can reach the friend on the day of the order at the earliest.

0049When such an order is carried out, the center server 12 instructs the image server in the minilab 3a to output the prints of the pictures a and c, while notifying the image server of the network address of the laboratory server in the minilab 3b which stores the picture c (106). In this manner, the laboratory server in the minilab 3a can obtain the digital image data of the picture c by a transfer of the data from the laboratory server in the minilab 3b (107). Likewise, the center server 12 instructs the printing of the picture b to the minilab 3b and notifies the laboratory 3b of the network address of the laboratory server in the minilab 3a which stores the picture b (108) . In this manner, the laboratory server in the minilab 3b can obtain the digital image data of the picture b by a transfer of the data from the laboratory server in the minilab 3a (109). By such transfer processing of the digital image data, the pictures a and c are printed at the minilab 3a and provided to the customer (110), while the picture b is printed at the minilab 3b and provided to the customer's friend (111). In this system if the customer notifies the friend of the customer's password, the friend can order a picture he/she wants directly.

0050As shown by the above examples, according to the network photograph service system of the present invention, the printing service can be received upon necessity, at a desired place, and in a shorter time than before, regardless of the location of the laboratory where the first prints have-been ordered. This is extremely convenient not only for the example shown in <figref idref="f0005">Figure 5</figref> but also for business, such as the case where a picture suddenly becomes necessary in a business activity going on from place to place.

0051In the embodiment described above, the center server 12 stores the thumbnail images for the access via the network while the laboratory server 8 stores the high resolution image data for printing. However, it is needless to say that the center server may store the high resolution image data for printing which are also used as the image for access, while the laboratory server 8 carries out printing only, without storing the high resolution image data.
