FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention, and 1 is a painting as an object. This painting 1 is photographed by a photographing device 2, and the photographing device 2 creates a color positive film 3a, a paper print 3b or a reflection original 3c. An ultra-high detail scanner 5 scans the color positive film 3a, the paper burner 3b, or the reflection original 3c, and creates image data by RGB signals (red green blue signals). The resolution of the ultra-high detail scanner 5 is set to 40 or more per 1 mm. RGB image data output by the ultra-high detail scanner 5 is 60M per image.
It is a large data before and after B and is recorded on the magnetic tape 6.

Reference numeral 7 is an image correction / editing apparatus, and 8 is a monitor thereof. A high-definition television monitor (the number of scanning lines is 1125, the aspect ratio is 9:16) is used as the monitor 8. The image correction / editing device 7 reads out the image data recorded on the magnetic tape 6 and performs a thinning process to convert the image data into data suitable for a high-definition television monitor. The image data converted in this way is supplied to the monitor 8, which causes
The monitor 8 reproduces the image of the painting.

The image correction / editing device 7 is provided with an operation console 7a. By operating a keyboard or a mouse on the operation console 7a, the image displayed on the monitor 8 can be corrected. ing. This fix is
For example, the color tone, the density, the strength of sharpness, etc. are performed, but the data correction is directly performed on the image data of about 60 MB. Then, the corrected image data is recorded on the magnetic tape 10.

Next, 11 is an image database, which sequentially reads and stores the image data recorded on the magnetic tape 10, and outputs the image data designated by the data retrieval device 12. In this case, the image data is associated with an identification code for identifying it, and a search is performed using this identification code.

Reference numeral 13 is a data conversion device for appropriately converting the image data output by the data search device 12,
Image data thinning processing and data format change processing according to the media are performed. 15 and 16 are CDs
A (compact disc) manufacturing device and an NTSC video recording device, which respectively manufacture a CD 17 and record a video tape 18 on the basis of image data supplied from the data conversion device 13.

Reference numeral 20 denotes a high-definition television monitor driving device, which causes the high-definition television monitor 21 to display the image data supplied from the data conversion device 13. Reference numerals 23 and 24 denote a printer and a secondary original document producing device, respectively, which produce a hard copy 25 based on the image data supplied from the data converting device 13 and copy it to a 4 × 5 inch film (or 35 mm film). A next original (positive or negative film) 26 is created. A printing device 30 prints the B full-version poster 31 and postcards based on the image data supplied from the data conversion device 13.

B: Operation of the Embodiment Next, the operation of this embodiment having the above configuration will be described. A color positive film 3a on which the image of the painting 1 is printed,
The paper burning 3b or the reflection original 3c is scanned by the ultra-high detail scanner 5, converted into RGB image data, and recorded on the magnetic tape 6.

Then, the image correction / editing device 7 reads out the image data recorded on the magnetic tape 6, thins it out, and displays it on the monitor 8. Here, the operator operates the keyboard and the mouse on the console 7a to make a correction edit on the displayed image. For example, if the painting is old and has a reddish discoloration,
Visually judge and adjust to obtain the correct color tone. Then, the corrected and edited image data is recorded on the magnetic tape 1.
It is recorded at 0.

The image data recorded on the magnetic tape 10 is stored in the image database 11. When the operator operates the data search device 12 to search for desired image data, the searched image data is output from the image database 11. Then, the operator instructs the data conversion device 13 on which medium to reproduce the image data.

Here, when the printing device 30 for printing the B full-version poster 31 is instructed, the data conversion device 13 does not perform thinning processing, and an image of about 60 MB per image output by the data search device 12 is output. Output the data as it is. As a result, the printing device 30 performs poster printing with extremely high dot density. That is, since the image data is as large as around 60 MB, it has a sufficient size and quality as a printed matter.

On the other hand, when another medium is selected,
The data conversion device 13 performs thinning processing of image data according to each medium, data structure changing processing, trimming processing, and the like. For example, when the high-definition television monitor reproducing device 20 is selected, it is 1/10 compared to the above case.
Since the amount of data is sufficient, the image data output by the data search device 12 is subjected to a thinning-out process commensurate with this, and further converted into a signal format compatible with a high-definition television monitor.

C: Effect of Embodiment In this embodiment, the following effects are obtained. If the image data of the painting of the museum is stored by the system of this embodiment, the painting is stored as digital data that does not change over time. Moreover, since it is possible to reproduce an image that is almost the same as the original image, you can create a positive or negative film of the same quality as the original,
There is no need to take the original picture again. By the way, it is well known that when an original image is photographed, the original image will be damaged and deteriorated due to its illumination or the like. However, according to the present embodiment, the number of times the original image is photographed can be greatly reduced. It is extremely suitable in terms of points. In addition, in the present embodiment, when the picture is in a bad state, the image is reproduced after being corrected and saved, so that the reproduced image is good regardless of the saved state of the original picture.

When reproducing an image on a high resolution monitor,
Although there is a case where it is desired to enlarge and display a part of the painting, according to the present embodiment, for example, an enlarged image can be obtained by reproducing a part of the stored image data without thinning it. On the other hand, conventionally, in order to partially expand,
It was necessary to separately store image data corresponding to the enlarged image. Further, the image data stored in this embodiment is
Since it is a set of color dots and does not employ a storage method using a special method, data conversion to various media is easy.

In the present embodiment, it is possible to reproduce on a plurality of media having different formats and display data amounts, but it is only necessary to input the original image once, so-called single source / multimedia conversion. Has been realized.

If this embodiment is applied to an art museum, printed matter of exhibits or color slides can be provided to visitors, and services can be improved.

D: Modification If the image data stored in the image database 11 can be exchanged by communication, for example, it is possible to construct a system that can mutually use the data of paintings in museums around the world. it can.

It can also be applied as a still image storage system for use in displaying moving images.

Instead of the magnetic tape 6 used in the embodiment, a storage medium such as a magneto-optical disk, an optical disk, a tape for 8 mm video may be used.
