Therefore, there are a photographing method and printed matter in consideration of a precise photographing preparation stage.

Description

  The present invention provides high-resolution data even when image data of a subject photographed by a photographing apparatus (such as a film-type camera or a digital camera) equipped with a high-resolution lens is in focus at all positions and is displayed at an equal magnification or enlarged display. The present invention provides novel high-quality captured image data capable of reproducing the original subject, a method for producing the same, and a printed matter thereof.

When you want to obtain detailed image data about a subject with a photographing device such as an optical camera or digital camera, a high-resolution lens such as a telephoto lens is used to focus on a predetermined range. A photographing means is employed.
On the other hand, when shooting an entire large subject that cannot be covered by focusing, a wide-angle lens that covers a wide range can be used so that the entire range can be grasped uniformly without focusing on a specific range. Shooting is performed.
Therefore, for items with high academic and cultural value and artwork that require both the whole subject and details in detail, it is only possible to create and provide image data that is divided into the whole and details. There was no means.

However, with the conventional techniques as described above, it has been impossible to obtain one image data excellent in detail in details and overall visibility.
In other words, for example, if you want to study ancient Japanese paintings, picture scrolls, folding screens, etc. that are of high cultural and academic value, but you cannot easily touch the original, It can be obtained only as a plurality of image data divided into parts, and it is difficult to study the entire structure at the same time while grasping the entire structure.
In particular, with partial detailed image data given in advance, there is no guarantee that the part desired by the researcher can always be obtained. The situation is the same for those who want a collection of drawings, scrolls, folding screens and other forms of painting from an artistic point of view.
In addition, due to improvements in printing technology and printing device performance, even large-sized paper with a side of 2 m or more can be printed as a single printed matter in some cases. Since the entire image cannot be processed as a single image data while reproducing every detail of the subject in detail, details such as full-scale drawings, picture scrolls, and folding screen paintings are possible even if possible in terms of printing technology. Can not be provided as a reproducible. In other words, the current printing technology is based on paper, cloth, wooden boards and glass that preserves the details at the time of production of two-dimensional representations such as drawings, picture scrolls, and folding screens. Although it is possible to actually print on a medium such as a board, there is no precise image data that is seamlessly integrated into one for executing such printing. Furthermore, even if it is possible to obtain a certain portion previously captured as detailed image data in the prior art, it is impossible to freely obtain a full-size display of an arbitrary portion of the whole. .
Note that prominent photographers, etc. may be asked to shoot pictures with high cultural value, such as pictures, scrolls, folding screens, etc., but in this case, focus, exposure, shooting angle and lighting are applied. The photographer's creativity has been demonstrated in some sense, and even though it is excellent as a photographic art work, it is usually not satisfactory as a material reproducibility as the actual image data of the subject. is there.

Means for solving the problem

The present invention was devised by repeating experiments and examinations for solving the problems in the prior art as described above, and cannot be regarded as in focus by a high resolution lens such as a telephoto lens. The entire subject having a considerable size is in a single image data, and every part of it is in focus, and it is possible to display an enlarged or larger image at an arbitrary size. The method for producing data and the printed matter thereof have been established, and are specifically as follows.

(3) As a preparatory step for photographing a flat subject, the distance between the precisely flattened photographing board and the photographing device equipped with the high resolution lens is fixed as a predetermined distance, and the reference center described on the photographing board is fixed. The point of adjustment and the intersection of the perpendicular to the shooting board from the center of the lens of the shooting device installed so as to face the shooting board exactly coincide with the shooting board, and the reference center point is the center. As shown in the figure, the reference frame line displayed on the shooting board and the grid scale on the focusing glass attached to the shooting device are superposed and adjusted so that the predetermined shooting range is covered with the focus adjusted. Fix the shooting conditions as a whole by fixing the light irradiation conditions uniformly,
As the shooting execution stage, the subject is positioned and set on the shooting board so that the desired location of the planar subject is in focus and can be taken sequentially in an accurate and detailed manner. Each divided part of a planar subject divided into a plurality of parts by moving the target positional relationship, and taking a plurality of divided image data by sequentially photographing while having some overlapping photographing parts at the boundary part,
As a combination integration processing step of each divided image data using a computer, the divided image data is taken into a computer and converted into digital divided image data, and the adjacent planar divided image data are combined to form an original planar object. When creating one digital image data for the entire image, the above-mentioned overlapping photographed portions of adjacent digital images are integrated at the pixel level so that blurring, overlapping display portions and missing portions do not occur, and other images The digital image data after combination integration processing maintains accuracy and detail in the shooting execution stage by not performing correction processing as much as possible, and it is like a faithful duplicate document as image recording data for the entire subject. Excellent reproducibility, full display on the monitor, as well as partial equal magnification and enlarged display of any part The method for manufacturing a high-quality photographic image data, characterized in that it is assumed possible.

Action (1) One piece of digital image data that can be displayed on a monitor having high resolution capability such as a computer by an image photographed accurately and in detail by a photographing device equipped with a high resolution lens, When all the displayed positions are in focus and an arbitrary portion of the image data is appropriately selected, the corresponding portion is in focus and can be displayed at the same magnification and magnification. Even if the subject is large, such as a picture scroll, folding screen picture, or drawing, at least 1.5m on a side, and in many cases over 5m, it reproduces detail and accuracy in all parts. However, it can be displayed as a computer monitor, and all parts can be displayed at the same size (full size) or appropriately enlarged, so that the detail and correctness can be displayed. While maintaining the accuracy, partial printing at a desired size at a desired location and full-size printing can be performed freely.
(2) A plurality of images captured accurately and in detail by a photographing apparatus equipped with a high resolution lens are combined to reproduce the entire subject as one digital image data accurately and in detail. When performing combination processing as image data, image correction processing other than integration processing at the pixel level of the boundary portion is not performed as much as possible, so that accuracy and detail at the time of shooting are maintained, and therefore after combination integration processing Because the digital image data of the camera is excellent in faithful material reproducibility as the image recording data of the subject, the highest level of reproducibility in the photographing device to be used is achieved at all locations, The smooth integration process that is virtually impossible to recognize The reproduction of the subject can be made excellent in reproducibility.
(3) As a preparatory step for photographing a flat subject, the distance between the precisely flattened photographing board and the photographing device equipped with the high resolution lens is fixed as a predetermined distance, and the reference center indicated on the photographing board is fixed. The point of adjustment and the intersection of the perpendicular to the shooting board from the center of the lens of the shooting device installed so as to face the shooting board exactly coincide with the shooting board, and the reference center point is the center. As shown in the figure, the reference frame line displayed on the shooting board and the grid scale on the focusing glass attached to the shooting device are superposed and adjusted so that the predetermined shooting range is covered with the focus adjusted. By fixing the light irradiation conditions uniformly, the shooting conditions as a whole are fixed, so that the relationship between the subject and the shooting device is aligned with a clear standard. In addition, it corrects subtle distortions and displacements of the lens and imaging device using objective reference points and reference lines, so that inaccuracies in the image data caused by the subject's own distortions are corrected based on the reference. It can be assumed that the value of the material is not impaired. Moreover, since all the shooting conditions are fixed and the divided images are shot, it can be considered as if the entire image was shot simultaneously, and from this point, the document value can be high.
(4) As the shooting execution stage, the subject is positioned and set on the shooting board so that the desired portion of the planar subject is in focus and can be taken in order accurately and in detail, and the distance from the shooting device is fixed. Since each of the divided parts of a planar subject divided into a plurality of parts by moving the relative positional relationship between them is sequentially taken while having some overlapping photographing parts at the boundary part, it is made into a plurality of divided image data. In combination with the fixed shooting conditions as described above, it is possible to obtain reproducible image data with high duplicated document value for the subject by combining and integrating only the overlapping shooting portions.
(5) As a combination integration processing step of each divided image data using a computer, the divided image data is taken into a computer and converted into digital divided image data, and the adjacent digital divided image data are connected to each other to obtain an original plane. When creating one digital image data for an entire subject, the above-mentioned overlapping photographed portions of adjacent digital images are integrated at the pixel level so that blurring, overlapping display portions, and missing portions do not occur. In addition to the above-mentioned requirements, the detailed and accurate reproduction of the subject at the highest level of the photographing device used is reproduced in all cases. It is possible to create one piece of image data at a location.
(6) The whole or desired portion of the photographic image data produced by the method for producing high-quality photographic image data of the present invention can be obtained in a desired size as an excellent reproduction reproduction document while maintaining detail and accuracy. By making it a printed material, two-dimensional representations such as picture scrolls, folding screen paintings, and drawings, which would be quite large as a whole, are made with paper, wooden boards, and glass in a state that preserves the precision at the time of production. It can be printed on a medium such as a board, and it can be produced easily and inexpensively with quality higher than that of expensive duplicates. Will be able to.

Some examples of the specific embodiments of the present invention described above will be described below with reference to the accompanying drawings.
FIG. 1 is a schematic diagram of a single image data 1 that is created by the image production method according to the present invention and that is created in 1602 in the Tohoku University Library collection and has a subject “Asia National Map”. The original subject is an original manuscript that is divided into two parts, east and west. In the figure, these two parts are combined into one world map. The size of the original subject is 169 cm long x 188 cm wide on the left and right. The original is a world map created by Italian Jesuit member Mateo Ricci (1552-1610) during the Christian mission in China, and was shipped in Japan during the isolation period.
Although it is impossible to grasp from the state shown in the figure, the name of each country, place name, and various explanatory texts are written in Chinese on the original subject together with the world map at the time. It can be understood that such map display and character display can be preserved in the actual image data 1 of the present invention without sacrificing the details and accuracy even if the image data is displayed entirely on a computer monitor or the like. It has become. The image data 1 is an image obtained by dividing the left and right sides of the original subject into 4 and 8 respectively, and using a telephoto lens with a distance of 2.66 m between the subject and the photographing device (optical camera) 2 and a high resolution lens of 480 mm. It was taken.
FIG. 2 shows a specific resolution of such image data 1. That is, it shows the actual display status of the same-size display portion 3 surrounded by the square in FIG. 1, and describes the vicinity of Honshu in Japan. As shown in the figure, it is understood that the shapes and names of Honshu and Shikoku, country names, local names and explanations are described in detail and clearly in Chinese text. This reproduces the same sharpness as the original full-scale display of the original subject ("Kunikuni full view"), and such accurate and detailed sharpness of the image data 1 shown in FIG. It is also realized in the whole part.
Next, the method for producing the image data 1 of the present invention as described above will be described by dividing it into a “shooting preparation stage”, a “shooting execution stage”, and a “combination integration process stage”.
(1) Shooting preparation stage:
In the present invention, this photographing preparation stage is very important. Here, it is possible to obtain accurate and clear image data 1 about the subject by performing a firm advance preparation according to a certain standard.
First, a photographing board 4 is prepared which is precisely flattened for accurately setting a planar subject such as pictures, scrolls and folding screens. In the present invention, it is necessary to focus on the entire subject in detail and to reproduce the clear and detailed image data 1 accurately. For this purpose, the photographing board 4 for setting the planar subject itself has slight distortion and the like. It is necessary to be flattened precisely.
As the photographic board 4, a floor surface of a photographic studio or the like that is sufficiently leveled to ensure precise flatness can be used. The image data 1 according to the present invention for the above-mentioned “All countries in FIG. 1” in FIGS. 1 and 2 also has a photographing board 4 on the floor surface, and the photographing device 2 fixed above it faces directly downward. It was taken. In the following, description will be made using the procedure in the case where the floor surface is precisely leveled and flattened as described above to obtain the photographing board 4 as a representative.
When the photographing board 4 as described above is prepared, the photographing apparatus (camera) 2 is positioned next to the board. As shown in FIG. 3, the vertical line is dropped from the center of the lens 5 of the photographing apparatus 2 which is fixed above the photographing board (floor surface) 4 and is directed directly below at a predetermined distance, and intersects with the floor surface 4. Let the point be the reference center point 6. When the floor surface 4 is used, it is accurate and simple to determine the reference center point 6 by hanging a thread 8 with a weight 7 as an adjustment means from the center position of the lens 5. Of course, a laser pointer or the like may be used as another adjustment means, but it is unexpectedly difficult to detect a point that hangs down accurately with respect to the floor surface 4.
On the floor (photographing board) 4, a plurality of reference frame lines 9 as shown in FIG. 4A are expressed so as to surround the reference center point 6. This is the area of the subject that can be photographed with a single shutter operation. The number of pictures, scrolls, and folding screens to be photographed is divided into several parts, how much resolution is desired, and how much. For example, when shooting with an 8 × 10 inch film, select from the range of 50 cm long × 62.5 cm wide to 120 cm long × 150 cm wide. In this case, the existing high-resolution lens 5 can capture a divided image having sufficiently desirable details and accuracy.
The reference frame line 9 may be described on the photographing board 4, but a sheet-like member displaying the standard frame line 9 is separately manufactured and set on the photographing board 4 as necessary. Also good. There is no problem if the reference center point 6 is appropriately adjusted even at this setting stage. That is, after the reference frame line 9 described in the sheet-like member is placed on the floor surface 4, the reference center point drawn at the center of the reference frame line 9 is the position of the weight 7 that is suspended by the thread 8 that is the adjusting means. You may do according to 6.
Next, it is necessary to correct subtle deviations and distortions in the photographing area of the subject with respect to the photographing board (floor surface) 4 with the high-resolution lens 5 attached to the photographing apparatus 2. That is, the high-resolution lens 5 must be used in order to achieve the accuracy, detail, and sharpness required for the image data 1 of the present invention in the imaging region. ) Will cause subtle shifts and distortions in the surrounding area. If this is left alone, accurate reproducibility cannot be maintained even if the captured divided images are combined, and if the correction is made to match the wrinkles, it is possible to reproduce the original subject. It is necessary to eliminate such misalignment and distortion in the shooting preparation stage.
In order to eliminate the deviation and distortion, the high-resolution lens 5 is attached to the photographing apparatus (camera) 2 which is accurately set with respect to the photographing board (floor surface) 4 according to the above-described procedure. A focus glass 10 with a grid scale schematically shown in b) is attached as shown in FIG. 3, and the four corners of the reference frame line 9 covering the desired photographing area and the reference center point 6 are in focus. This is done by observing the reference frame line through the focus glass 10 and observing whether or not it clearly overlaps a predetermined grid scale.
Since the relative positional relationship between the photographing device 2 and the photographing board 4 is accurately determined by the above procedure, if there is a slight shift or distortion, it can be attributed to the nature of the lens 5 or the photographing device (camera) 2 body. Therefore, the image data 1 of the present invention is required within the desired shooting region by performing appropriate corrections excluding this while maintaining the focused state. Therefore, it can be determined that it is guaranteed that accurate and detailed photographing without any deviation or distortion is possible.
In the present invention, the in-focus state is a state in which at least the characters on the newspaper can be read clearly at least at the four corners and the reference center point 6 in the desired shooting area surrounded by the reference frame 9. is there. 1 and FIG. 2, the distance between the subject and the photographing device (camera) 2 equipped with the high-resolution lens 5 is also prepared when the image data 1 of the present invention is created for the “Asia National Map”. The image is fixed at 2.66 m, and the original subject of the above size is divided into eight parts, and the above-mentioned focusing is performed with the reference frame line 9 of 90 cm long × 112.5 cm wide as the photographing region.
In addition, in the image data generation method of the present invention based on the premise that the subject is dividedly photographed, the illumination conditions for the photographing board (floor surface) 4 are naturally set in order to uniformize and fix the photographing conditions of the divided image data. Are also considered to be strictly constant.
As described above, in the present invention, each image data 12 photographed as a divided image by setting and fixing a strict photographing condition as a preparation stage for actually photographing a subject such as a picture, a picture scroll, or a folding screen picture. In order to ensure the highest possible quality of reproduction materials, such as accuracy, detail, and reproducibility.
In the above description, the case where a sufficiently flat and leveled floor surface is used as the photographing board 4 has been mainly described. However, what is important in this photographing preparation stage is that the photographing board 4 and the photographing device 2 are accurate. In other words, the reference center point 6 and the center of the high resolution lens 5 are precisely aligned. Therefore, if an appropriate adjustment means using a laser beam or the like is employed, for example, a technique for appropriately photographing preparation even with a technique in which the photographing board 4 is set up vertically with respect to the wall surface and the photographing device 2 is precisely positioned with respect to it. It can be a stage.
(2) Shooting execution stage:
After passing through the above-mentioned careful shooting preparation stage, the process proceeds to the shooting execution stage. The drawings, scrolls, folding screens, and the like to be the subject of the present invention have an area of at least several square meters, usually more than that, and are detailed and clear over the details required as the image data 1 of the present invention. Obtaining a copy material with excellent reproducibility cannot be obtained with a single shutter operation. Therefore, the shooting is executed by dividing the image data 1 into a size capable of shooting that achieves high quality.
That is, taking FIG. 1 as an example, a photographic board (floor surface) 4 depicting a photographing region capable of photographing that realizes high quality that requires the original subject, “Asia National Map”, is provided. 8 is divided into 8 as indicated by the virtual dividing line 11, and each is sequentially photographed while passing through an accurate positioning operation, so as to fit within the appropriate reference frame 9 shown in FIG. This is image data 12.
Shooting of the divided image data 12 must be performed without losing the shooting conditions precisely determined in the above-described shooting preparation stage. Therefore, it is necessary to pay sufficient attention to this point even when the relative positional relationship between the subject and the photographing device (camera) 2 is moved and each divided portion is photographed sequentially. Although the method of moving the subject side is adopted when dividing the “Kunikuni map” of FIG. 1 into eight, a method of moving the photographing device 2 can also be adopted. Further, in order to photograph each divided portion, a careful positioning operation is performed so that the center and the four corners are arranged within the reference frame line 9 that accurately uses the center and the four corners.
In addition, each divided portion is photographed so as to have some overlapping photographing portions with respect to the adjacent divided portions. This is because the divided image data 12 is combined and integrated into one image data 1 for the original subject so that no missing portion of the data is generated, and at the boundary portion between the divided image data 12 and 12 is effectively identified. This is necessary in order to realize an unsatisfactory smooth combination integration process. This overlapping photographing part usually has a width of about several centimeters, but may be changed appropriately.
While maintaining the precise shooting conditions at the shooting preparation stage, the above-described shooting is performed on each divided portion, so that it is possible to obtain divided image data that is accurate and detailed in detail and excellent in reproduction of the original subject as a duplicate document. It will be.
(3) Combination integration processing stage of each divided image data:
In the present invention, a plurality of divided image data 12 obtained by the above procedure is taken into a computer using a scanner or other appropriate input device to form digital image data, which is combined again therewith, so that an entire original subject is obtained. One image data 1 is reconfigured.
At this time, each overlapped image data obtained by performing the shooting operation while maintaining and maintaining the overlapping shooting portions of the boundary portions between the adjacent divided image data 12 while superimposing and collating them. In principle, there is almost no contradiction such as blurring or distortion in the overlapping photographing portions of the boundary portions between the 12 portions. However, it is impossible to completely deny the possibility of inconsistencies at fine points. However, since the divided image data 12 is obtained by strictly managing the imaging conditions as the standard as described above from the preparation stage, even if such a mismatch occurs, the cause is easily identified. Therefore, it is possible to perform an optimal correction process so as to accurately reproduce the original subject, and the value as a duplicate material is not impaired.
In this respect, in the conventional image joining, the divided image data itself is not obtained under the strict management of the photographing conditions as in the present invention, and the boundary portion is naturally inconsistent. Yes. Moreover, since the shooting conditions are not fixed, it is difficult to identify the cause of the discrepancy, and even if the image correction processing for matching is performed, the basis for this is unclear. Usually it is damaged.
In addition, in the case of image joining in the prior art, the joined end portion of the boundary part is inevitably left due to the fact that the divided images cannot be taken under exactly the same shooting conditions, and the same size display on the monitor, etc. In this case, the joint portion can be clearly observed. On the other hand, in the present invention, since processing at the pixel level is performed as a combination integration process at the boundary portion between adjacent divided images and the two are merged, the same size display or several times enlarged display is performed. However, it is possible to achieve such a finish that the joint end cannot be confirmed. By strictly managing the shooting conditions, it is also helped that the overlapping shooting portions of the adjacent divided images 12 are obtained as substantially the same. In the present invention, in the image data 1 after the combination integration processing, It is virtually impossible to confirm the boundary between the divided images 12.
In the present invention, image correction processing using a computer other than such combination integration processing of boundary portions is not performed in principle. That is, correction processing such as adjusting the color tone, increasing the sharpness of the image, or deforming and connecting the drawn lines is basically unnecessary. This is because such processing should not be performed from the viewpoint of accurately reproducing the state of the original subject as a duplicate material, even if there is an effect such as making the completed image more beautiful. Even if there is a problem that requires fine correction, the cause of the problem can be easily determined in the present invention in which strict shooting condition management is performed, so that the correction is suitable for reproducing the state of the original subject that was shot. It can be processed, and there is no risk of losing its value as a duplicate material. Therefore, the image data 1 of the present invention is excellent in duplicating document value for storing subject data captured as precisely as possible by the photographing apparatus (camera) 2 to which the high resolution lens 5 is attached.
Through the above-described “shooting preparation stage”, “shooting execution stage”, and “combination integration process stage of each divided image data”, the image data 1 unique to the present invention shown representatively in FIGS. 1 and 2 Is produced. Such image data 1 usually has a data amount of several G level, but there is no inconvenience for recording on various recording media that have recently become widespread, and the computer itself has a much improved performance. Therefore, the amount of data is not so large as to hinder display on the monitor or print processing. In addition, since large-capacity data communication such as broadband is realized, the image data 1 of the present invention can be sufficiently handled by data distribution using the Internet or the like. Furthermore, the image data 1 of the present invention can be produced not only to be displayed on a monitor or as a printed material at the same size as the original size but also to be able to withstand enlarged display of several times.
Furthermore, according to the current advanced printing technology, the image data realized by the manufacturing method as described above can be used for various types of print media such as paper, cloth, wooden boards, glass boards, and so on. It is possible to print in a desired size even at any desired location, as well as the whole, as the detail saved at the time of production of the original material such as a folding screen picture. Therefore, it is a matter of course to print on the same medium as the original material to make a printed material worthy of a duplicate material, and print on a print medium that cannot exist at the time of production of the original material to make a product with a distinct texture Etc. can be easily realized.

According to the present invention as described above, divided shooting and a computer in which shooting conditions are strictly controlled for a large-sized subject that has conventionally been unable to obtain a shot image in a state that is in focus at every detail. Precise combination and integration processing using the image makes it possible to create a single image data in digital format that is accurate, vivid and detailed in terms of reproduction material details of subjects such as ancient Japanese drawings, scrolls and folding screen paintings. It is possible to provide a display that can be freely displayed and printed at a desired magnification with respect to the whole or a part.
In particular, original drawings, scrolls, and folding screen paintings are expressed on Japanese traditional Japanese paper, but this Japanese paper has deep surface irregularities and a thick texture. However, photography that reproduces the exact texture of the real thing was more difficult than in other countries. It has become possible for the first time to finely digitize arts and crafts. As a result, the expectation that such unique Japanese arts and crafts will be widely distributed to the world as digitized content is also increasing.
If such sophisticated electronic content is printed on an appropriate print medium using today's advanced printing technology, it is possible to easily and inexpensively produce a printed material that achieves a quality higher than that of an expensive duplicate by copying. Since it is possible to print on a medium different from the original image, an unprecedented product having a new texture can be provided.
Further, if a highly accurate divided image can be obtained at a level where the image integration processing of the present invention is possible, the present invention can be applied not only to a planar subject but also to a stereoscopic subject.
Furthermore, assuming the existence of detailed and clear image data for the entire subject, for example, the color tone at the time of creating the original picture is reproduced by a method such as elemental analysis for a colored picture scroll or folding screen picture, before the aging change It is also possible in principle to reproduce a fresh state, and in any case, it proposes a new form of copy storage materials as digital images for various culturally valuable items. It is an invention that arouses various demands and has high industrial value.

When creating one digital image data for the entire image, the above-mentioned overlapping photographed portions of adjacent digital images are integrated at the pixel level so that blurring, overlapping display portions and missing portions do not occur, and other images The digital image data after combination integration processing maintains accuracy and detail in the shooting execution stage by not performing correction processing as much as possible, and it is like a faithful duplicate document as image recording data for the entire subject. Excellent reproducibility, full display on the monitor, as well as partial equal magnification and enlarged display of any part The method for manufacturing a high-quality photographic image data, characterized in that it is assumed possible. Excellent reproduction reproduction data while maintaining the detail and accuracy of the whole or desired portion of the photographic image data produced by the method for producing high-quality photographic image data described in claim 3 A printed matter characterized by being printed in a desired size.
