Then, the divided pictures are arranged so that the arrangement relation of those divided picture data obtained for reproducing the original target picture expressing articles as picture data can be defined, and the overlapping picture data parts of the edge parts of the adjacent divided picture data are digitally processed for erasing the overlap relation so that a series of picture data can be obtained. The picture data are continuously reproduced from the desired position of the picture data to a proper direction while maintaining the arrangement relation of the divided picture data, and presented on a monitor.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a case in which a two-dimensional image expression such as a picture scroll, a painting, a mural, etc. is stored as a plurality of digital image data which are appropriately divided in order to record and save clearly and in detail. The present invention relates to a method for continuously restoring and reproducing an original image state and a storage medium therefor.

[0002]

2. Description of the Related Art It has been a practice to take pictures of two-dimensional expressions such as picture scrolls, paintings, and murals, to make them into illustrations and to spread them widely. In this case, in order to photograph and record the details of the target two-dimensional expression in detail and sharply, it is usual to divide the original image into a plurality of sections and perform precision photographing for each section.

[0003] In recent years, digital technology has advanced, so that digital photography is often performed in place of conventional photographic technology. In this case, too, in order to precisely convert an original image into a digital image and save it, It is divided into a plurality of image data and processed.

[0004]

However, in the above-described conventional technique, it is possible to observe the details of each of the divided parts as much as possible. It is difficult to grasp it.
In addition, in the case of simply photographing (digitally photographing) the entire original image, no matter how recent photography techniques have been advanced, the original image has not been precisely reproduced.

Further, even if the divided images of the precisely photographed original image are arranged in order, these divided images are photographed with overlapping portions at the end portions in order to prevent the occurrence of missing portions from the original image. Therefore, the reproduction of the original image in a natural state cannot be realized simply by arranging the images in order.

[0006] Therefore, it is desirable to reproduce a two-dimensional expression with one image data that can accurately reproduce the details of the original image and clearly grasp the state of the whole image. Has not been realized at present.

[0007]

[0012]

In order to record the details of a two-dimensional image representation in detail and completely, the target image representation is divided into a plurality of sections having overlapping portions at the ends and formed by precision photographing each section. By using a plurality of digital image data, it becomes a plurality of divided image data that can precisely reproduce the details of the target original image, and by giving overlapping portions at the ends, there is no missing part of the image data Can be

[0013] The divided image data obtained to reproduce the original target image representation as image data are arranged so as to determine the positional relationship between the divided image data, and the overlapping image data portion at the end of each adjacent divided image data is determined. Since a series of image data is obtained by digital processing so as to eliminate the overlapping relationship, the precision-divided divided image data can be converted into a series of image data that can reproduce the original image state as it is.

By maintaining the positional relationship of the divided image data determined from the desired position of the image data and continuously reproducing it in an appropriate direction and expressing it on the monitor, the precisely photographed image data can be displayed on the monitor. Thus, the reproduction can be performed sequentially and continuously, and it is possible to perform the same operation as when approaching the original original image itself for detailed viewing.

By using a picture scroll or mural as a target image representation, it is difficult to reproduce and view even the details as a series of images, such as on a monitor. It is possible to appropriately reproduce and watch even a target image expression.

The image data obtained by the method for continuously expressing divided image data according to the present invention as described above is stored in an appropriate storage medium, for example, a video tape, a digital video tape, a compact disk, a server machine on a network, or the like. This allows the user to appropriately reproduce and watch.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An example of a specific embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a simplified flowchart showing a procedure for creating a storage medium (such as a video tape) for executing the method for continuously expressing divided image data according to the present invention. In the flowchart shown in the drawing, the process is started from a state in which a “positive” film in which the details of a target two-dimensional image representation are divided into a plurality of parts and precisely photographed is prepared.

First, the "positive" data divided into a plurality of parts is "high-precision scanning" by a high-performance scanner, and all the target two-dimensional image data is taken into a computer. Arrange the positional relationship so that the image data can be reproduced.

Here, the divided image data taken into the computer and arranged in a positional relationship is overlapped with the adjacent image data at the end of adjacent image data in order to prevent a missing part of the image when precision photographing is performed. Therefore, the "image trimming" process is performed on the computer so that the overlapping image portion is eliminated and the original two-dimensional image data can be accurately reproduced as it is.

Each of the divided image data which has undergone the "image trimming" process has a smooth image because the overlapping image portion between the adjacent image data has been eliminated and the positional relationship between the respective image data has been arranged. It is possible to perform continuous reproduction expression on the original, and since the original is the image data obtained by “high-precision scanning” of the “positive” data that was originally taken with precision, the target two-dimensional image expression is detailed in detail It is possible to process and reproduce as one image data while taking in the image data.

The emphasis in the present invention is on a series of process steps up to the above-mentioned "high-precision scanning". Such divided image data is stored in an appropriate storage medium (video tape, digital video tape, compact disk, network, etc.). In order to record and commercialize the data on the above server machine, for example, it is desirable to complete it by the following steps.

That is, "scroll creation" and "trimming (UP etc.)" are performed in parallel on the divided image data that has been subjected to the image processing by the computer, and then the necessary "editing work" is performed. The image data determined by the "editing work" is "narrated" and "music inserted" for commercialization, and the storage medium storing the divided image data according to the present invention is "completed" as a product.

An example of the embodiment of the present invention will be described with reference to a divided image of a specific two-dimensional image representation.
(A), (b) and (c). Here, for a picture scroll in which it is impossible to precisely record the details in one frame, the first three parts of the picture scroll recorded as a plurality of divided images 1, 2, and 3 are continuously shown. .

That is, an overlapped image portion 4 exists at the end portion of FIGS. 2A and 2B which should be continuous with each other.
An overlapping image portion 5 exists at an end portion where (b) and (c) should be continuous, and an overlapping image 6 also exists at an end portion where the divided image shown in FIG. It can be understood that it exists. It is clear that the state of the original two-dimensional image representation cannot be reproduced even if the divided images 1, 2, and 3 are arranged in order while such overlapping image portions 4, 5, and 6 exist.

Therefore, these divided images 1, 2, and 3 are taken into a computer by "high-precision scanning" shown in FIG. 1, and the overlapping relationship between the overlapping image portions 4, 5, and 6 is eliminated by "image trimming" processing. In addition, by rearranging the positional relationship between the divided images 1, 2, and 3 so as to reproduce the original two-dimensional image representation, the original two-dimensional image representation can be accurately refined as substantially one image data. Will be stored as digital data in the computer.

Thus, the divided image data 1, 2, 3
Is a series of image data shown in FIG. That is, it is understood that a series of picture scrolls can be expressed on a monitor in a state where the details are precisely reproduced. The portion shown in FIG. 3 is a portion represented by the divided image data from the beginning of the picture scroll to the third sheet. Of course, several tens of divided image data up to the end image data of the original picture scroll are likewise shown. By forming a series of image data, the whole picture scroll can be expressed as substantially one continuous image data.

In the case where a series of image data of the entire picture scroll as described above is recorded on a video tape or other recording medium and reproduced in detail on a monitor so as to be expressed in a state that can be viewed, the beginning of the picture scroll data is required. From the part to the end, we have to take a continuous and sequential expression by breaking the narrative. In other words, since the picture scroll data is a series of very long image data, if it is represented in a state that can be viewed on a normal monitor, the detailed representation of the picture scroll recorded appropriately cannot be reproduced on the monitor. It is.

In addition, watching the story in sequence from the beginning of the picture scroll in this way is also consistent with the original viewing method of the picture scroll, and it is difficult to view the picture scroll by hand. It can be understood that the present invention realizes continuous viewing, which was not possible in the past, as a viewing method of an image expression.

Although the above description has been given of the case where a horizontally long one such as a picture scroll is employed as a two-dimensional image representation, the present invention is also applicable to a large-sized painting or a horizontal or vertical tens of meters or more. It can also be applied to realize a continuous expression method for two-dimensional expressions that cannot be displayed on a normal monitor while reproducing details, such as a huge mural painting that extends. It is possible.

Also, an example has been described in which a video tape is used as a storage medium and a continuous continuous expression is performed from the beginning of a picture scroll. When a storage medium is used, it is easy to reproduce the image data from an appropriate position, and since the positional relationship between the divided image data is maintained in an orderly manner, the image data is directed in an appropriate direction from the reproduction position. Image data can be continuously reproduced smoothly. In addition, it is also possible to perform a process of cutting out image data at a desired location and creating new different data.

Further, it is impossible to perform precision photographing again or it is very difficult to obtain a two-dimensional image expression (for example, image data that is difficult to photograph due to designation of a cultural property, and that is extremely lost or damaged at present. Even if it is not possible to obtain a picture scroll, painting, mural, etc.), there are many things that are converted into divided image data as "positive" data, and these are expressed as original as possible and It should be understood that the present invention is also effective for use.

[0033]

According to the present invention as described above, it is difficult to display image representations, which are difficult or difficult to display on a normal monitor, on the basis of the finely divided image data, so that they can be viewed in detail. It can be continuously expressed in a state and can be viewed by ordinary consumers in a state that is almost the same as the original image expression, and image expressions with high artistic value, cultural value, historical value, It is intended to provide a new viewing method for past image data in which it is difficult or impossible to obtain new image data by taking a new image. is there.
