Image data compression rate Is sent to the data transmission means. In the present invention, the control data holding means holds control data representing the relationship between the print size, the resolution, and the image data compression rate instead of holding control data representing the relationship between the print size and the image data compression rate. It is characterized by doing. The image reading unit preferably sets the resolution according to the print size based on the control data of the data holding unit.
[0007]
[Action]
A developed photographic film cartridge is set in the film scanner. The film scanner pulls out a photographic film from a photographic film cartridge, and reads an image of each frame as digital image data. The read digital image data is displayed as a list on a color monitor, for example. The user refers to this list display and specifies a print target frame and inputs print order data including a print size and the number of prints. The data transmission unit determines the optimum number of pixels based on the print size, and sends the digital image data of this number of pixels and the print order data to a print production means, for example, a digital printer of a print finisher. The digital printer performs printing based on the digital image data with the size and number of sheets specified by the print order data.
[0008]
The image reading means performs low resolution reading for displaying an image and high resolution reading corresponding to the print size. In addition to the image reading with the resolution changed, the image may be read at a high resolution and the image data may be thinned according to the image display or print size. Further, in the transfer of image data to a print finisher, the resolution and the image data compression rate are changed according to the print size. This change increases the resolution and decreases the image data compression rate as the print size increases. The relationship between the print size, the resolution, and the image data compression rate is determined in advance and stored. The relationship between the print size and the resolution may be stored on the digital printer side in addition to being stored on the film scanner side. In this case, the print size is first sent to the digital printer side on the film scanner side, and the optimum resolution and image data compression rate for the print size are obtained on the digital printer side, which are sent to the film scanner side.
[0009]
The digital printer creates a print based on the digital image data and the print order data. This print is specified by the user based on the user identification data in the print order data. Based on the delivery method instruction data, it is sent to the user who is the print orderer by mail or home delivery, and is directly delivered to the user at the finishing contractor or DP reception store. Further, fee settlement processing is performed based on fee payment instruction data of print order data. For example, in addition to selecting automatic bank withdrawal, bank transfer, credit card, prepaid card payment, etc., in the case of direct delivery processing, cash payment is also selected.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a schematic diagram showing a digital printing system of the present invention. On the user 10 side, a film scanner 11 and a color monitor 12 are provided. On the side of the print finisher 13, a reception work station 14, a large-capacity storage device 15, printers 16, 17 and 18, an invoice issuing printer 19, and a delivery bag printing printer 20 are provided. The film scanner 11 of the user 10 and the reception work station 14 of the print finisher 13 are connected via modems 21 and 22 and a telephone line 23. The workstation 14, the storage device 15, and the modem 22 constitute a database 24.
[0011]
As shown in FIG. 2, the film scanner 11 on the user 10 side includes a film feeding unit 25, a film image reading unit 26, an input image memory 27, a processing control unit 28, a magnetic recording / reproducing unit 29, an image processing unit 30, and a working unit. The image memory 31 includes various data memories 32, a monitor display control unit 33, and a data communication unit 34.
[0012]
The film feeding unit 25 includes a cartridge loading unit 41 into which the film cartridge 40 is loaded, a spool rotating shaft 42, a guide roller pair 43, a film feeding roller pair 44, and a film storage unit 45. The cartridge loading portion 41 is composed of a housing recess, and a lid is attached to the opening of the recess so as to be freely opened and closed. When the film cartridge 40 is set in the loading section 41, the spool is engaged with the spool rotation shaft 42 and is rotatably connected. The spool rotation shaft 42 is rotated forward and backward by a film feed motor 46, whereby the spool rotates in the film feed direction or the winding direction.
[0013]
The film cartridge 40 has a film leading-out function, and the leading edge of the photographic film 47 is fed out from the film entrance by rotating the spool in the film feeding direction. The film feed roller pair 44 is rotated by a film feed motor 46 to pinch a photographic film 47 from the film entrance and draw it out of the cartridge 40. When the film feed is performed by the film feed roller pair 44, the transmission of the film feed motor 46 to the spool rotating shaft 42 is cut off. The drawn photographic film 47 is stored in a curled state in the cylindrical film storage unit 45.
[0014]
Between the guide roller pair 43 and the film feed roller pair 44, a film image reading unit 26 and a magnetic recording / reproducing unit 29 are arranged. The film image reading unit 26 includes a light source unit 48 and an imaging unit 49. The light source unit 48 includes a fluorescent tube 50, a reflector 51, and a diffusion plate 52 having light emission characteristics that match the characteristics of a photographic film.
[0015]
The magnetic recording / reproducing unit 29 reads photographing information from the transparent magnetic recording layer of the photographic film 47 by the magnetic reproducing head 53 and sends it to the processing control unit 28. The shooting information used in this embodiment is a frame number, and an image of each frame is specified using this frame number. If necessary, shooting date / time data and title data are also used. In this case, the shooting date / time and title of each frame are displayed on the color monitor 12 at a position adjacent to each frame. The magnetic recording / reproducing unit 29 writes the title data and the like from the processing control unit 28 on the transparent magnetic recording layer at the position corresponding to each frame as necessary by the magnetic recording head 54.
[0016]
The imaging unit 49 is configured by a scanner including a line type image area sensor. The image pickup section 49 scans the image of each frame of the photographic film 47 in synchronization with the film feed and stores it in the input image memory 27.
[0017]
The image processing unit 30 uses the work image memory 31 to perform gamma correction processing, color correction processing, trimming processing, character data insertion synthesis processing, enlargement / reduction processing, data compression processing, and the like.
[0018]
The processing control unit 28 includes a microcomputer, and performs image reading and order processing by controlling each unit in sequence. For this reason, a keyboard 55, a mouse 56, and a memory 32 for storing various data are connected to the processing control unit 28. By operating the keyboard 55 and the mouse 56, the processing control unit 28 is switched to an image reading display mode, a print designation mode, a high resolution reading mode, and an order processing mode.
[0019]
In the image reading display mode, the processing control unit 28 images each frame by the imaging unit 49 in synchronization with the feeding of the photographic film 47 and writes the captured data in the input image memory 27. The image processing unit 30 creates an index image for list display. As is well known, this index image is a list of frames arranged in a matrix.
[0020]
Since high-resolution image data is not required when the index image is created, the imaging unit 49 is reduced in resolution by pixel combination, and image reading is performed in this state. Each frame of the index image read in this manner is sequentially written in the work image memory 31 to create an index image. The created index image is read by the monitor display control unit 33 and displayed on the color monitor 12.
[0021]
In the print designation mode, the index image displayed on the color monitor 12 is observed to specify the print target frame. This specification is performed by positioning the cursor in the screen of the color monitor 12 with the mouse 56 in the display area of the frame to be printed and clicking the left button (positive button) of the mouse. In addition, the frame number of each frame may be numerically input from the keyboard. Further, other input means such as a light pen or a touch panel may be used.
[0022]
In this embodiment, the normal size and the number of shots “1” are set by default so that the input of the print size and the number of prints can be simplified. Therefore, when nothing is instructed, the normal size and the number of shots “1” are designated. In addition, when a powerful vision size or panorama size other than this is designated, or when a plurality of images are designated, these inputs are performed by a well-known designation method. The print instruction data including the inputted print target frame number, print size, and print number data is stored in the memory 32.
[0023]
In addition to the normal size, powerful vision size, and panorama size, the print size information can also specify a paper size. For example, in addition to the general E size and L size, a cabinet size and a large size such as A4, A3, A2, A1, etc. can be specified. The E size, L size, cabinet size, and the like are printed by a silver salt photographic printer using a color photosensitive material as described later, and large sizes such as A4 and A3 are printed by an ink jet printer or a thermal printer.
[0024]
In the high resolution reading mode, the frame number of the frame to be printed and the print size are read from the print order data memory 32. Then, the resolution at the time of image reading is set based on the print size. When a large print size is designated, the high resolution mode is designated, and the resolution is set lower as the print size becomes smaller. Further, when each size of powerful vision print and panoramic print is set in addition to the normal print, an image is read from an area corresponding to each size.
[0025]
In the order processing mode, print order data other than the print instruction data is input. These print order data include delivery date desired date / time instruction data, delivery method instruction data, fee payment method instruction data, and user identification data. Once each of these data is input, it is stored in the memory 32. When the next order data is input, the print order data when the previous order was placed is displayed on the color monitor 12, and the re-input of the common data is omitted. When the input of each data is completed, the process control unit 28 controls the data communication unit 34 to transfer each data to the database 24 of the print finisher 13. For this data transfer, a well-known personal computer communication method is used, and the order data is sent to the database 24 via the telephone line 23.
[0026]
The user identification data identifies the user and is composed of the user's name, address, postal code, telephone number, ID number, and the like. A user ID number and a password are issued by placing an order once or registering a user before placing an order. Therefore, in subsequent orders, the user is identified only by inputting the user ID number and the password. For frequently ordered types, registering them with order numbers such as order 1 and order 2 makes it possible to omit the input of a series of print order data.
[0027]
The desired delivery date / time instruction data indicates the desired delivery date / time. The desired delivery date / time is set in advance by a print finishing company, and a plurality of types of delivery date / time are set and selected from these. For example, delivery within 12 hours after acceptance, delivery within 24 hours after acceptance, delivery within 2 days after acceptance, etc. are selected. Instead of such a selection method, a method for designating a desired delivery date and time may be used. The delivery method instruction data indicates the delivery method, and mail, home delivery, store receipt, etc. are selected.
[0028]
The fee payment method instruction data indicates a fee payment method, and credit card payment, automatic bank transfer, bank transfer, prepaid card payment, etc. are selected when delivery by mail or home delivery is desired. In addition to cash payment, cash payment is selected when receiving delivery is desired.
[0029]
The reception workstation 14 on the side of the print finishing company 13 has a system configuration including a high-function and high-speed computer because it handles a large amount of data. The reception workstation 14 incorporates well-known database software, and a database 24 is constructed by the workstation 14, the storage device 15, and the modem 22. The database software corresponds to the order processing software of the film scanner 11 on the user 10 side. Upon receiving print order data from the user 10 side, the reception workstation 14 transfers the reception number, delivery date, fee, and the like.
[0030]
In the digital printers 16, 17 and 18, photosensitive materials and recording materials having different paper sizes are set, and these printers 16 to 18 perform printing of different sizes. The printers 16 and 17 are composed of a silver salt color digital printer, and scan exposure of a silver salt color photosensitive material (color paper) based on the digital data to print and expose an image. A color paper of a positive / positive type is used, and the color paper is printed and exposed with a positive image.
[0031]
As shown in FIG. 3, the silver salt color digital printer 16 includes a scanning exposure type printing exposure unit 60 using laser light, modulates a light beam based on image data, and synchronizes it with the feeding of the color paper 61. Then, each of the yellow, magenta, and cyan photosensitive layers of the color paper 61 is subjected to scanning exposure, whereby each image is printed and exposed. The printed color paper 61 is developed by a paper processor 62, and then separated for each frame based on the cut mark, so that an L-size print 63 is created. Further, a back printer 64 is provided, and this back printer 64 records a reception number, a user ID number, and their barcode on the back surface of the color paper 61 corresponding to each image. The other silver salt color digital printer 17 is configured in the same manner. The printer 17 is set in a cabinet size, and a cabinet size print 65 is created.
[0032]
In addition to the scanning exposure method using laser light, a surface exposure method or a line exposure method using a CRT, a liquid crystal display panel, or the like may be used for the printing exposure unit 60. Further, instead of modulating the light beam, scanning exposure may be performed using a micromirror device. In the micromirror device, mirrors (micromirrors) having an extremely small size are arranged in a line or a matrix, and the tilt angle of each micromirror is controlled to deflect incident light.
[0033]
When color paper of a negative / positive type is used, the image data is positive / negative converted. This positive / negative conversion may be performed by the image processing unit of the workstation 14 in addition to the image processing unit of the digital printers 16 to 18. The image processing units of the digital printers 16 to 18 perform gamma correction and matrix correction so that the density and color balance of the obtained print are optimized.
[0034]
The printer 18 is a well-known ink-jet color digital printer. The printer 18 is selected when the printing method instruction data of the user order data is an ink jet method, and creates a large size print 66 such as A0 to A4 size. For this reason, recording papers of various sizes are set in the printer 18, and corresponding recording papers are selected according to the size designation. The printer 18 is also provided with a back printer, and a reception number, a user ID number, and a barcode thereof are recorded on the back side of the recording paper.
[0035]
As shown in FIG. 1, the bill issuing printer 19 prints a bill 67 based on the data of the workstation 14. The delivery bag printing printer 20 prints an address, name, zip code, etc. on the delivery bag 68. Further, the printers 19 and 20 record the reception number, the user ID number, and their barcode for collation with each print.
[0036]
Next, the operation of this embodiment will be described with reference to FIG. First, the user 10 obtains a print finisher list, selects an optimum print finisher 13 in consideration of the nearest store, type of print format, fee, delivery method, and the like. And register as a user.
[0037]
In this user registration, the reception workstation 14 issues a user ID number and a password to the user 10, and thereafter receives a print order by comparing the user ID number and the password.
[0038]
Next, the user 10 sets the film cartridge 40 in the film scanner 11 and designates the image reading display mode. In this mode, in order to create an index image, all the frames of the photographic film 47 are read by the imaging unit 49, processed by the image processing unit 30, and then sequentially written into the work image memory 31 to be indexed. An image is created. The created index image is displayed on the color monitor 12 via the monitor display control unit 33.
[0039]
Next, the processing control unit 28 is set to the print designation mode, and a frame to be printed is specified by the mouse 56 and the print size and the number of sheets are input. These print instruction data are stored in the memory 32.
[0040]
When the input of all the print instruction data is completed, the processing control unit 28 is set to the high resolution reading mode. In this high resolution reading mode, the image of the frame to be printed is read at a resolution corresponding to the print size based on the print instruction data stored in the memory 28. That is, when the print size is large, the number of pixels is increased, and as the size is decreased, the number of pixels is decreased. In addition to the normal size, when a powerful vision size or a panorama size is designated, an image is read from an area corresponding to these sizes.
[0041]
The read image data is subjected to image processing by the image processing unit 30. Image processing includes, for example, gamma correction, matrix correction, character illustration composition, enlargement / reduction, trimming, image composition, and the like, and these image processes are selectively performed. Next, the image data that has undergone image processing is compressed, for example, by JPEG (Joint Photographic Experts Group). The data compression rate can be changed according to the print size. When the print size is large, the compression rate is lowered and image quality deterioration is suppressed. Also, the smaller the print size, the less noticeable the image quality degradation, and the higher the compression rate. The data compression method is not limited to JPEG, and other known compression methods may be used. The compressed image data is recorded in the memory 32. The image data of each frame is stored corresponding to the print instruction data.
[0042]
When the image reading of each frame to be printed is completed, the processing control unit 28 is set to the order processing mode, and desired delivery date / time instruction data, delivery method instruction data, and fee payment method instruction data are input. When data transfer is instructed after this input, the processing control unit 28 controls the data communication unit 34 to send the print order data to the database 24 of the print finisher 13.
[0043]
Since the workstation 14 manages the current total number of orders and the delivery date, based on the image size and the number of prints of the received print order data, whether or not the desired delivery date is met is determined by the number of orders and prints of other users. To calculate the print finish time. Then, the delivery time is calculated by adding the delivery processing time to the print finishing time. If the calculated delivery date exceeds the desired delivery date, the workstation 14 sends an unprocessable message to the user 10. In this case, the user 10 selects whether to change the desired delivery date and time or to cancel the order. When the calculated delivery date is within the desired delivery date, the workstation 14 sends the receipt number, delivery date, and fee to the user 10.
[0044]
The film scanner 11 on the user 10 side displays the received receipt number, delivery date, and fee on the color monitor 12. The user 10 observes the color monitor 12 and sends the receipt number and the image data to the print finisher 13 if this charge and delivery date are acceptable. Further, when the print order is stopped due to a delivery date or a charge problem, it is not necessary to transfer the image data, so the data transfer cost can be reduced by this amount.
[0045]
When the print finisher 13 receives the receipt number and the image data, the image finisher and the print order data are associated with each other and stored in the storage device 15 based on the receipt number. Thereafter, printing is performed based on the image data by a printer designated by the print order data. If confirmation of the delivery date and the charge is not required, the user may send print order data and image data when placing a print order.
[0046]
The workstation 14 prints each order in the order of delivery based on the received content. At this time, the printers 16 to 18 to be used are selected based on the print instruction data. Then, printing is performed for the designated number of sheets with the designated print size. For example, when a normal L size print is designated, an L size print 63 is created using the printer 16. When cabinet size print is designated, a cabinet size print 65 is created using the printer 17. When an A3 size print is designated, an A3 size print 66 is created using the inkjet printer 18.
[0047]
Further, the back printers of the printers 16 to 18 print the reception number, the user ID number, and their barcode on the back surface of the prints 63, 65, 66. These reception number, user ID number, and bar code are used for verification with the invoice and the delivery bag in a later delivery process.
[0048]
Invoices and delivery bags are printed in parallel with printing or before and after printing. In the bill issuing process, the workstation 14 uses the bill issuing printer 19 to print the details of the billing fee, the receipt number, the user ID number, and the barcode of these numbers in a predetermined format, and the bill 67 Issue. Similarly, the workstation 14 uses the delivery bag printing printer 20 to send the user's postal code, address, name, telephone number, delivery code, etc., receipt number, user ID number, and barcode of these numbers to the delivery bag. Print to 68. These zip code and address name are specified based on the user ID number of the print order data. When a delivery bag with a transparent window is adopted, the address name print on the delivery bag may be omitted by entering an address and the like on the invoice. Various delivery bags 68 are prepared according to the print size. For example, in the case of large-size printing such as A0 to A3, a cylindrical body is used. Further, in addition to direct printing on the delivery bag 68, it may be printed on a label. In this case, this label is attached to the delivery bag 68.
[0049]
The same receipt number and bar code are recorded on the finished prints 63, 65, 66, invoice 67, and delivery bag 68. Therefore, collation is performed on the basis of these, and the product type code is stored after being packed. Thus, processing such as mailing, home delivery, delivery, etc. is selected. This bagging is done manually based on the receipt number, and the receipt number barcode is automatically read with a barcode reader and automatically packed, and then sorted according to each delivery type. Good.
[0050]
The print fee is settled by the method instructed by the fee payment method instruction data. For example, in the case of a prepaid card payment method, the user purchases a prepaid card at a print finishing company or the like and inputs the card ID number as print payment method instruction data, so that the workstation 14 charges the prepaid card. Printing can be performed up to the limit.
[0051]
In the above embodiment, the silver salt color digital printers 16 and 17 and the ink jet color printer 18 are used. However, in addition to this, a heat development transfer type color printer, a color thermal printer, and a color laser printer may be used. . Of course, when performing monochrome printing, a monochrome printer is used.
[0052]
Further, as print order data, data indicating index printing, multi-printing, sticker printing, character composition printing, and monochrome printing may be added. Seal prints are affixed to release paper, peeled off and affixed to other things, and many are used in combination with multi-prints.
[0053]
Image correction processing instruction data may be added as the print order data. In this case, the image of the finished finish displayed by the operator of the print finisher 13 is observed, and the image and the color balance are optimized. Correction processing is performed. In this case, the correction processing fee is added to the billing fee. In addition to the image data, magnetic recording data such as photographing information recorded on the transparent magnetic recording layer may be transferred to the print finisher 13. In this case, the print quality can be improved by using, for example, print quality improvement information (PQI) in the photographing information. In addition to the information recorded on the photographic film, image data from a television receiver or a video player may be transferred using the film scanner of the present invention. In this case, these images are printed. be able to.
[0054]
In the above-described embodiment, the reading at the time of creating the index image is performed by combining the pixels of the imaging unit 49 to reduce the resolution. However, in addition to this, the imaging unit 49 reads the high-resolution image data. The resolution may be reduced by thinning out.
[0055]
The data transmitting means first transmits the print size data to the print finishing company, and the print finishing company uses a combination that optimizes the resolution of the image reading means and the image data compression rate in the data transmitting means based on the print size data. Control data for selecting and changing the resolution and the image data compression rate may be sent to the user side. In this case, since the resolution and data compression rate corresponding to the print size can be finely set, image data suitable for the print size can be obtained. In addition, although the combination of the resolution and the image data compression rate is obtained, other than this, only the resolution or only the image data compression rate may be obtained, and these may be changed independently.
[0056]
【The invention's effect】
As described above, according to the first aspect of the present invention, the frame recorded on the photographic film is read as digital image data by the image reading means, the read image is displayed by the image display means, and the displayed image is displayed. The image to be printed is identified by observing the image, the print size and the number of prints for the identified image to be printed are designated, the digital image data from the image reading means is set to the number of pixels corresponding to the print size, and the digital image data and print Since the print order data specifying the size and the number of copies is transmitted to the print production means, unlike the conventional method of printing all shot frames, only the necessary frames can be printed. Moreover, even in the case of reprinting prints, it is possible to easily perform reprinting without having to go to the store where the print production means is installed.
[0057]
According to the second aspect of the present invention, the image reading means sets the resolution according to the print size, so that efficient image reading is possible. According to the third aspect of the present invention, the resolution and / or the compression rate of the image data are changed according to the print size, and this change increases the resolution or the compression rate of the image data as the print size increases. Since the image data is lowered, the image data can be optimized for the print size, and the image quality that can withstand viewing can be ensured. In addition, data transfer can be performed efficiently.
[0058]
In a fourth aspect of the invention, the data transmission means transmits the digital image data based on control data, and the control data changes the resolution of the image reading means set by the print production means based on the print size data. In addition, since the image data compression rate in the data transmission unit is changed, the resolution and data compression rate can be finely set according to the print size.
