[0023] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The microfilm management system of the present invention will now be described with reference to the accompanying drawings, in which preferred embodiments are shown, although the invention may be embodied in many different forms and is not limited to the embodiments set forth herein.

[0024] For example, although the configuration, operation, etc. of the microfilm management system will be described in this embodiment, the same effects can be achieved by the executed method (steps), device, computer program, etc. The program in this embodiment may be provided as a non-transitory computer-readable recording medium, may be provided so as to be downloadable from an external server, or the program may be started in an external computer to implement its functions at a client terminal (so-called cloud computing).

[0025] In addition, in this embodiment, the term "unit" may include, for example, a combination of hardware resources implemented by a circuit in the broad sense and software information processing that can be specifically realized by these hardware resources. In this embodiment, "information" is represented by, for example, a physical value of a signal value representing a voltage or current, a high or low signal value as a binary bit collection consisting of 0 or 1, or a quantum superposition (so-called quantum bit), and communication and calculation can be performed on a circuit in the broad sense.

[0026] A circuit in the broad sense is a circuit realized by appropriately combining a circuit, circuitry, a processor, memory, etc. In other words, it includes a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), an LSI (Large Scale Integration), an ASIC (Application Specific Integrated Circuit), an FPGA (Field-Programmable Gate Array), etc.

[0027] Microfilm records paper documents, historical documents, drawings, etc. at a reduced size compared to the originals. Microfilm records images of documents, drawings, etc. that have been photographed at a reduced size. The photographed images are called frames.

[0028] On one microfilm, documents of different sizes, such as A3 and A4, are photographed at reduced size and recorded as images (frames). Because the reduction ratio is the same, documents of different sizes have different frame sizes even on the microfilm. For example, A3 size is twice the size of A4 size, so the size of the frames recorded on the microfilm will also be twice as large.

[0029] Microfilms include roll film, microfilm jackets, microfiche, aperture cards, etc. In this embodiment, the microfilm is a roll film on which an image is captured in the longitudinal direction of the film.

[0030] <System Overview> Fig. 1 is a block diagram showing the configuration of a microfilm management system in this embodiment. As shown in Fig. 1, the microfilm management system 0 includes a microfilm management device 1, a scanner 2, and a user terminal 3. The microfilm management device 1 is configured to be able to communicate with the scanner 2 and the user terminal 3 via a network NW.

[0031] In this embodiment, the microfilm management device 1 operates as a server, and the user terminal 3 operates as a client terminal. In this manner, multiple users can check the strip images via their respective user terminals 3. The microfilm management device 1 may be a personal computer or the like, and may have the functions of the user terminal 3.

[0032] The microfilm management device 1 may generate strip images using electronic data of the microfilm. In this case, the microfilm management device 1 may receive input such as the length of the strip of the generated strip image in the longitudinal direction. The microfilm management device 1 may also receive a designation of the overlap length of the strip.

[0033] A general-purpose server computer, a personal computer, etc. can be used as the microfilm management device 1. It is also possible to configure the microfilm management device 1 using a plurality of computers.

[0034] The scanner 2 is composed of a scanning device for scanning the microfilm, and a control device such as a personal computer that runs a dedicated application or the like. The scanner 2 scans the microfilm to generate electronic data of the microfilm including frames recorded on the microfilm (long data of one microfilm, etc.). The scanner 2 further generates a strip image using the generated long data of one microfilm (data of one entire microfilm including frames and spaces between frames) or the like. The scanner 2 may also generate a strip image when scanning the microfilm to generate electronic data (without generating long data of one microfilm). The scanner 2 accepts input of the longitudinal length of the strip of the generated strip image, and a designation of the overlap length of the strip. The scanner 2 transmits the generated electronic data of the microfilm and / or strip image to the microfilm management device 1 and / or the user terminal 3.

[0035] The user terminal 3 processes and displays the generated strip images, etc. The user may also input the longitudinal length of the strip of the generated strip image, etc. via the user terminal 3. The user terminal 3 may transmit to the microfilm management device 1 the data received from the scanner 2 and / or the information accepted from the user.

[0036] In this embodiment, the network NW is an IP (Internet Protocol) network, but there is no restriction on the type of communication protocol, and further, there is no restriction on the type and scale of the network.

[0037] <Hardware configuration> Fig. 2 is a hardware configuration diagram. As shown in Fig. 2(a), the information processing device 10 (microfilm management device 1) has a control unit 101, a storage unit 102, and a communication unit 103, which are used to perform the functions of each unit and each process.

[0038] The control unit 101 includes one or more processors such as a CPU (Central Processing Unit), and controls the overall operation and processing of the information processing device 10 by executing the microfilm management program of the present invention, an OS (Operating System), browser software, and other applications.

[0039] The storage unit 102 is a hard disk drive (HDD), a solid state drive (SSD), a read only memory (ROM), a random access memory (RAM), a linear tape open (LTO), a tape drive, etc., and stores the microfilm management program according to the present invention and data used when the control unit 101 executes processing based on the program. The control unit 101 executes processing based on the microfilm management program stored in the storage unit 102, thereby realizing a functional configuration described below.

[0040] The communication unit 103 executes communication control with the network NW, and performs input required to operate the information processing device 10 and output related to the operation results.

[0041] As shown in FIG. 2(b), the terminal device 9 (scanner 2, user terminal 3) has a control unit 91, a memory unit 92, a communication unit 93, an input unit 94, and an output unit 95, and is used to perform the functions of each unit and each process.

[0042] The control unit 91 of the terminal device 9 includes one or more processors such as a CPU, and controls the overall operation processing of the terminal device 9. The storage unit 92 of the terminal device 9 is an HDD, SSD, ROM, RAM, or the like, and stores the above-mentioned applications and data used when the control unit 91 executes processing based on a program.

[0043] A communication unit 93 of the terminal device 9 controls communication with the network NW. An input unit 94 of the terminal device 9 is a mouse, keyboard, or the like, and inputs operation requests from a user / provider to the control unit 91. An output unit 95 of the terminal device 9 is a display, or the like, and displays the results of processing by the control unit 91, etc.

[0044] <Functional components> 3, the microfilm management device 1 includes a receiving unit 11, a determining unit 13, and a complementing unit 14. The scanner 2 includes a transmitting unit 21 and a strip image generating unit 12. The user terminal 3 includes a transmitting unit 31 and a display processing unit 32.

[0045] The arrangement of these functional components is one example, and part of the functional configuration of the microfilm management device 1 may be arranged in the scanner 2, the user terminal 3, and one or more devices configured to be able to communicate with the microfilm management device 1. Also, part of the functional configuration of the scanner 2 may be arranged in one or more devices configured to be able to communicate with the microfilm management device 1, the user terminal 3, and the scanner 2. Similarly, part of the functional configuration of the user terminal 3 may be arranged in one or more devices configured to be able to communicate with the microfilm management device 1, the scanner 2, and the user terminal 3.

[0046] <Data Structure> 4 shows an example of the data structure stored in the storage unit in this embodiment. The storage unit of the microfilm management device 1 stores microfilm information, strip image generation information, strip image information, complementary strip image information, and the like.

[0047] The arrangement of each data is just an example, and some or all of the data stored in the memory unit of the microfilm management device 1 may be stored in one or more devices configured to communicate with the scanner 2, the user terminal 3, and the microfilm management device 1.

[0048] Microfilm information is information about digitized microfilm. As shown in FIG. 4(a), microfilm information includes microfilm data, which is electronic data on the microfilm, and is managed by a microfilm ID. In addition, microfilm information may include the capacity of the microfilm data, the date and time when the microfilm was digitized, etc. Furthermore, the electronic data of the digitized microfilm may be in any format.

[0049] The strip image generation information is information about strips for generating strip images from microfilm. As shown in FIG. 4(b), the strip image generation information includes the length of the strip to be generated and the length of the overlapping portion of the strip to be generated, and is managed by the microfilm ID.

[0050] The strip image information is information about the generated strip image. As shown in Fig. 4(c), the strip image information includes electronic data of the strip (strip image) and is managed by the microfilm ID. In this way, it is possible to manage which microfilm the strip image was generated from.

[0051] The complementary strip image information is information about the generated strip image and the complementary strip image. The complementary strip image information includes the generated strip image and the complementary complementary strip image, as shown in FIG. 4(d), and is managed by the microfilm ID. In this way, it is possible to manage which microfilm the generated strip image and the complementary strip image were from.

[0052] <Processing Flowchart> Fig. 5 is a flow chart of the process of digitizing the microfilm in this embodiment, and Figs. 6 to 9 are diagrams for explaining the digitization of the microfilm in this embodiment.

[0053] <Receiving electronic data> First, in step S501, the receiving unit 11 receives electronic data of the microfilm. Specifically, the scanner 2 scans the microfilm to generate electronic data (long data and / or strip images of one microfilm), the transmitting unit 21 of the scanner 2 transmits the electronic data, and the receiving unit 11 of the microfilm management device 1 receives the electronic data. In the strip images, there is an overlap of frames at the longitudinal ends of the nth strip image and the n+1th and / or n-1th strip images.

[0054] In this embodiment, the scanner 2 generates long data for one roll of microfilm, the strip image generation unit 12 of the scanner 2 generates a strip image having multiple frames in the longitudinal direction of the microfilm, and the receiving unit 11 of the microfilm management device 1 receives the strip image.

[0055] Alternatively, the microfilm management device 1 may include a strip image generating unit 12. In this case, the scanner 2 generates long data for one strip of microfilm, and the transmitting unit 21 transmits the long data to the receiving unit 11.

[0056] Furthermore, when the scanner 2 generates electronic data of a microfilm, it may generate a strip of image data instead of generating data for a single long strip of microfilm. For convenience of explanation, this embodiment will be described using an illustration in which all frames recorded on the microfilm are digitized. However, it is also conceivable that a microfilm may be digitized with some frames missing.

[0057] Figure 6(a) shows a digitized microfilm, with W1_n (n = 1, 2, ...) representing frames and W2 representing spaces between frames. Spaces between frames are the areas between frames where no images are recorded. The spaces (between frames) where no images are recorded are filled with a single color, such as black. Frames are recorded on the microfilm in rows along the length, as shown in Figure 6(a). When there is a single row of frames recorded on the microfilm, there will be a single row of frames for the rectangular image, as shown in Figure 6(a). When there are multiple rows of frames recorded on the microfilm, there will be multiple rows of frames for the rectangular image.

[0058] 6(b) shows a digitized microfilm, where W3_n (n=1, 2,...) represents a strip, and the strip image generating unit 12 generates an image of this strip (strip image). The strip W3_n (n=1, 2,...) is represented by a rectangle that encloses two diagonal lines.

[0059] <Generation of rectangular images> For example, the strip image generating unit 12 generates a strip image represented by a strip W3_1 having a plurality of frames W1_1 to W1_5 in the longitudinal direction of the microfilm, as shown in Fig. 6(b). The strip may include an incomplete frame (frame W1_5) as shown in Fig. 6(b). The strip image generating unit 12 generates a strip image having frames W1_1 to W1_5 recorded consecutively on the microfilm, as shown in Fig. 6(b).

[0060] Furthermore, the strip image generating unit 12 generates strip images of multiple strips W3_1, W3_2, ... as shown in Fig. 7(a). By using a strip image including multiple frames, a user can check multiple frames from one data, improving the overview for checking electronic data. Furthermore, by including multiple frames in a strip, the number of times a user has to turn pages when checking frames can be reduced, improving the page turning speed.

[0061] Fig. 7(b) shows a digitized microfilm, where the rectangular portion W4_n (n=1, 2, ...) surrounding the diagonal lines represents the overlapping of frames of two strip images. In Fig. 7(b), there is an overlapping portion W4_1 where a portion of a frame overlaps between strips W3_1 and W3_2. Strip W3_2 has an overlapping portion W4_1 with strip W3_1 and an overlapping portion W4_2 with strip W3_3.

[0062] The strip image generating unit 12 generates a plurality of strip images of strips W3_n (n=1, 2, . . . ) having overlapping portions W4_n (n=1, 2, . . . ) as shown in FIG. 7(b).

[0063] In this embodiment, the strip image generating unit 12 of the scanner 2 generates strip images based on electronic data of the microfilm scanned by the scanner 2. Alternatively, the microfilm management device 1 may be equipped with the strip image generating unit 12 and generate strip images. The scanner 2 or the microfilm management device 1 accepts the length of the strip and / or the length of overlap of the longitudinal ends of the strip. Alternatively, the user may input the length of the strip and / or the length of overlap of the longitudinal ends of the strip via the user terminal 3, and the transmission unit 31 may transmit the length accepted from the user to the scanner 2 or the microfilm management device 1.

[0064] A user or the like specifies the length of a strip and generates a strip image, which allows the strip image generating unit 12 to generate strip images of strips of the same length. Also, a user or the like specifies the overlap length of the longitudinal ends of the strip and generates a strip image, which allows the strip image generating unit 12 to generate strip images of the same overlap length. In other words, the strip image generating unit 12 can generate strip images at equal intervals in the longitudinal direction of the microfilm.

[0065] For example, when a user specifies a length of the strip of "100 mm" and a length of overlap (overlapping portion) of the strip of "30 mm," in FIG. 7(a), the strip image generation unit 12 generates a strip image in which the distance between sides S2 of strip W3_1 is 100 mm and the distance between side S2 (right side) of strip W3_1 and side S2 (left side) of strip W3_2 is 30 mm.

[0066] Alternatively, when the scanner 2 scans the microfilm and generates electronic data of the microfilm, it may simultaneously generate strip images. Even in this case, it is conceivable that the user or the like may specify the length of the strips and / or the overlaps in the strips.

[0067] <Judgment of strip images> 8 shows an example of a strip image generated from electronic data of a microfilm. The strip image generating unit 12 stores strips W3_n (n=1, 2, . . .) in the electronic data in a storage unit as strip images (image files, etc.).

[0068] In step S502, the determination unit 13 determines the degree of overlap between the end portion in the longitudinal direction of the n-th strip image and the end portion in the longitudinal direction of the n+1-th and / or n-1-th strip images. Specifically, the determination unit 13 determines the degree of overlap using template matching.

[0069] The determination unit 13 may calculate a similarity between the longitudinal end of the n-th strip image and the longitudinal end of the n+1-th and / or n-1-th strip images, and may make a determination using the similarity and a predetermined threshold. For example, the determination unit 13 determines that there is an overlap when the calculated similarity is equal to or greater than the threshold.

[0070] The longitudinal end of a strip (strip image) represents a certain length portion from the shorter side of the strip (rectangle). In Fig. 6(b) and Fig. 7(a), the strip is composed of sides S1 and S2. Since side S2 is shorter than side S1, the longitudinal end represents a certain length portion from side S2.

[0071] For example, in the rectangular image of Fig. 8, rectangular strips W3_1 and W3_2 share an overlapping portion W4_1 where overlapping frames exist. The overlapping portion W4_1 is the longitudinal end portion of rectangular strip W3_1 and the longitudinal end portion of rectangular strip W3_2. That is, in the rectangular image, the overlapping portion W4_1 of frames exists at the longitudinal end portions of rectangular strips (rectangular strip images) W3_1 and W3_2. The overlapping of frames at the longitudinal end portions may be an overlapping of only a portion of the frames.

[0072] The determination unit 13 makes a determination by comparing a certain length portion (longitudinal end portion) from the shorter side of the strip (rectangle) in the strip image.

[0073] For example, in the strip images of Fig. 8, the determination unit 13 compares the longitudinal end of strip W3_1 with the longitudinal end of strip W3_2 to make a determination. Since the longitudinal end of strip W3_1 includes parts of frames W1_4 and W1_5, and the longitudinal end of strip W3_2 includes parts of frames W1_4 and W1_5, the determination unit 13 determines that parts of the frames of each strip image overlap.

[0074] On the other hand, the longitudinal end of strip W3_1 includes parts of frames W1_4 and W1_5, whereas the longitudinal end of strip W3_3 does not include parts of frames W1_4 and W1_5, so the determining unit 13 determines that the frames of each strip image do not overlap. If a strip image of strip W3_2 is missing due to such a determination, this can be displayed. In addition, if some frames are missing, this can be displayed.

[0075] For example, if the determination unit 13 determines that the frames in each strip image do not overlap, it transmits information about the determination to the display processing unit 32. Then, the display processing unit 32 may display a message or the like indicating that the strip is missing based on the received information. By determining whether or not a strip is missing in this way, the comprehensiveness of the electronic data on the microfilm can be improved.

[0076] The determination unit 13 determines the degree of overlap at the longitudinal ends of the rectangular images. If the determination unit 13 determines that the longitudinal ends match, it further determines whether or not there is a gap between frames in the overlapping portion. Because the gap between frames is filled with one color, the determination unit 13 can determine whether or not there is a gap between frames in the overlapping portion.

[0077] <Frame Completion> In step S503, if there is no gap between frames in the overlapping portion, the complementing unit 14 complements the frame of the n-th rectangular image based on the frame of the n+1-th and / or the n-1-th rectangular image.

[0078] FIG. 9 shows an example of a strip image generated from electronic data of a microfilm. The overlapping portion W14_1 in FIG. 9 does not include spaces between frames. When the overlapping portion does not include spaces between frames, a frame is split as shown in FIG. 9. A frame is split when a complete frame is not included in any of the strip images. For example, when the overlapping portion W14_1 does not include spaces between frames as shown in FIG. 9, the complete frame W11_2 is not included in either strip W13_1 or W13_2.

[0079] On the other hand, the overlapping portion W4_1 in Fig. 8 includes the space between the frames, so no division of the frames occurs. In Fig. 8, the complete frame W1_4 is included in the strip W3_1, and the complete frame W1_5 is included in the strip W3_2.

[0080] FIG. 10 shows (a) a strip image with no gap between frames in the overlapping portion and (b) a complemented strip image. Since there is no gap between frames in the overlapping portion W14_1, the complementing unit 14 complements the strip W13_1 as shown in FIG. 10(b) based on a part of the frame W11_2 of the overlapping portion W14_1 of the strip W13_2. By complementing W5, the complementing unit 14 can generate a complemented strip including the complete frame W11_2, and can store it in the storage unit as a complemented strip image. By generating a complete frame, it is possible to improve the overview when a user or the like checks the frames.

[0081] <Setting the appropriate length of the overlapping part> Since there are documents of different sizes such as A3 and A4, frames of different sizes may be recorded on a microfilm, as shown in Figures 9 and 10. In Figures 9 and 10, frame W1_n (n = 1, 2, ...) and frame W11_n (n = 1, 2, ...) are different sizes.

[0082] The length of the longitudinal end where the overlapping frames exist (overlapping portion) may be set to 1.2 to 1.6 times the length of one frame recorded on the microfilm. Specifically, the length of the overlapping portion may be set to 1.2 to 1.6 times the length of the smaller frame.

[0083] For example, if the frames recorded on the microfilm are all the same size, then if the length of the longitudinal end where the frames overlap (e.g., side S3 in Figure 8) is made greater than the horizontal length of a frame recorded on the microfilm (e.g., side S5 in Figure 8), the overlapping portion will always include the spaces between the frames (in Figure 8, the overlapping portion W14_1 is made up of sides S3 and S4, and the frame is made up of sides S5 and S6).

[0084] If the length of the longitudinal end where the overlapping frames exists (for example, side S3 in FIG. 8) is made 1.2 times or more the width of one frame recorded on the microfilm (for example, side S5 in FIG. 8), the overlapping portion will always include the gap between the frames (in FIG. 8, overlapping portion W14_1 is made up of sides S3 and S4, and the frame is made up of sides S5 and S6). In this case, since the overlapping portion will always include the gap between the frames, the complement unit 14 does not need to complement the frames.

[0085] In other words, even if the sizes of the frames recorded on the microfilm are different, if the length of the longitudinal end where the frames overlap (for example, side S3 in FIG. 9) is set to 1.2 times or more the width of the largest frame recorded on the microfilm (for example, side S7 in FIG. 9), the overlapping portion will always include the spaces between the frames (in FIG. 9, the overlapping portion W14_1 is made up of sides S3 and S4, and the largest frame is made up of sides S6 and S7). On the other hand, in this case, the overlapping portion may become too long, and when two smaller frames (made up of sides S5 and S6) are placed side by side, both will be included in the overlapping portion, which may require the user, etc., to check the same frame several times when checking the strip image.

[0086] For example, since the size of an A3 document is twice the size of an A4 document, when A3 and A4 documents are recorded on microfilm, in Fig. 9, the length along the longitudinal direction of the A3-sized microfilm (e.g., side S7 in Fig. 9) will be twice the length along the longitudinal direction of the A4-sized microfilm (e.g., side S5 in Fig. 9). Therefore, if the length along the longitudinal direction of the microfilm of the overlapping portion is made 1.2 times or more the length along the longitudinal direction of the microfilm of the frame of the A3 document recorded on the microfilm (e.g., side S7 in Fig. 9), it is conceivable that two frames of the A4 document will be included in the overlapping portion.

[0087] In other words, when the frames recorded on the microfilm are different sizes, making the length of the overlapping portion along the longitudinal direction of the microfilm (for example, side S3 in Figure 9) more than 1.2 times the length of the largest frame recorded on the microfilm along the longitudinal direction of the microfilm (for example, side S7 in Figure 9) increases the effort required of users, etc. to confirm, so it is preferable to make it more than 1.2 times the length of the smaller frame along the longitudinal direction of the microfilm (for example, side S5 in Figure 9).

[0088] Also, by making the overlapping area 1.2 times or more the length of one frame, the possibility that the overlapping area will include the frame and all of the space between that frame and the one frame adjacent to it increases. For example, the possibility that the overlapping area will include all of the space between frames W2 in FIG. 6(a) increases. Furthermore, in order to more reliably include the frame and all of the space between that frame and the one frame adjacent to it, it is possible to make the overlapping area 1.3 times or more the length of one frame.

[0089] Also, in order to reduce the effort required for users to check, it is preferable that the length of the overlapping portion is short. Therefore, it is conceivable to set the length of the overlapping portion along the longitudinal direction of the microfilm to 1.5 or 1.4 times or less the length of one frame recorded on the microfilm.

[0090] Since most documents are A4 size, the length of the overlapping portion along the longitudinal direction of the microfilm can be set to between 1.2 and 1.6 times the length of the frame in which the A4 size is recorded. By using the length of the frame that is most likely to be recorded on the microfilm as the standard, it is possible to reduce the processing required to supplement the frames while preventing excessive checking by users, etc.

[0091] As described above, the configuration of the present invention can provide a new technique for digitizing and managing information recorded on microfilm. [Explanation of symbols]
