Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides an image file device that manages image information by storing an image input from an image input means in an image information recording means and displaying it on an image display means at any time. It is related to.

[Prior art and its problems]

In recent years, office automation has progressed rapidly, and there is a growing tendency for computers to be introduced into office equipment and for equipment to be interconnected through communication lines. In order to respond to such trends in computerization and communication, it is preferable that the information handled be stored in the form of electrical signals.

Therefore, image file systems that use electronic files (optical disks, magneto-optical disks, etc.) that record image information as digital signals have been attracting attention in recent years.

Image file system t4. Mainly because a large amount of image information can be recorded at high density in the form of electrical signals, it has the great feature of saving space and realizing high-speed retrieval.

Generally, in such an image file system, each time image information is input using an image input means such as a league, search data for the image information, that is, keywords, creation date, etc. of the image information is input using a keyboard. This search data is stored in an external storage device such as a floppy disk along with an address (track number, etc.) for storing this image information. The image information is then recorded on a disk of an electronic file device that can store a large amount of information. When searching and reading image information recorded in the electronic file device, the system is configured so that a keyword can be entered from the keyboard and the image information corresponding to this keyword can be called up from the electronic file device. Since search data must be input for each piece of image information stored in the electronic file, the image information that is retrieved from the electronic file in response to the keyword input from the keyboard is for each piece of image information. However, when searching for information such as photographs and pictures among image information, rather than searching for the desired image by keyword search, the operator searches while displaying the stored information such as photographs and pictures on a display device. There is a need to.

For example, when searching for a photo of a specific person or a specific object from among a large number of photos, searching for information using search data not only makes it impossible to immediately search for the desired image information, but also reduces search efficiency. This results in a significant decrease in operator fatigue. In this way, especially when searching for information such as photographs or drawings, it is easiest and most efficient to display the image information related to each item at once and select the desired image information from among them. You can search for information.

[Purpose of the invention]

The present invention has been made in view of the above points, and includes a heading information storage means for sequentially storing heading information obtained by reducing image information inputted into the image inputting means sequentially for each item, and a A large heading information storage means for further reducing each heading information and storing large heading information to be used as heading information of the heading information, and a writing command means for sending a write command to the heading information storage means and the large heading information storage means. The main heading page displayed on the image display means.

The purpose of the present invention is to provide an image file system that allows searching for image information such as photographs and pictures while sequentially searching the index pages.

Next, the flowchart in Figure 2 and Figures 3 (a) to (C)
), the control operation will be explained. Note that (1) to (14) in Figure 2 represent each step, and the image information to be input is item A, which has a total number of pages of 5.
It is assumed that the original of item B and the original of item B consisting of 3 pages in total are inputted successively.

In FIG. 3, (a) to (C) are diagrams explaining the storage state of image information stored in the optical disk device 13, and (a)
(b) represents the main heading page in which the heading page has been reduced, and (C) represents the main heading page in which the manuscript of item A consists of 5 pages in total, and (C) has 3 total pages.
This shows a state in which a heading page obtained by reducing the manuscript of item B consisting of pages is further reduced and stored in a large heading page used as heading information.

The operator inputs a command from the keyboard 2 while viewing the command image displayed on the image display device 14 (1)
0 Next, the CPU 3 judges whether the input command is a command to input image information 2), and if it is judged to be an input command, the document of item A consisting of 5 pages is sent to the image input device 12. A video signal converted into an electrical signal is input to the interface 11 and the bus 8. The data is sent to the magneto-optical disk device 13 and the page memory 6 via the magneto-optical disk "fintaface I2" (3).

The image signal sent to the magneto-optical disk device 13 is recorded in the next page area with two pages of a predetermined size original, that is, from the third page to the first page of the original of item A ( 00 Next, the column and row signals of the video signal sent to the page memory 6 are extracted in accordance with instructions from the CPU 3 at a predetermined clock, and image information (Fig. 3 (a) )) is stored in the page memory 7 (5), the CPU 3 determines whether all the manuscripts related to item A have been input.B)

(9) Return to step (1) and start inputting the manuscript of item B consisting of three pages. Note that each document of item B inputted from the image input device 12 is recorded sequentially from the ninth page in the page area of the magneto-optical disk device 13. Further, the heading make for item B stored in the page memory 6 is recorded on the eighth page of the page area of the magneto-optical disk device 13. Furthermore, when inputting item B, the magneto-optical disk device 1
The main heading page recorded on the first page of the page area No. 3 is read out to the page memory 7, and when all the originals for item B have been input, the main heading page is stored in the page memory 6 according to a command from the CPU 3. A video signal in which the heading page related to item B is further thinned out is added to the page memory 7 as shown in FIG. After erasing, the main heading page stored in the page memory 7 is written.

On the other hand, if it is determined in step (2) that an image display command has been issued, the main heading page stored on the first page of the page area of the magneto-optical disk device 13 is displayed according to the command from the CPU 3. The video signal is sent to the image display device 4 via the magneto-optical interface I2 + path 89 image display interface [3 for display (10). Next, the operator operates the keyboard 2 to select a desired item while looking at the main heading page that is displayed (11).Subsequently, the heading page of the item selected in step (11) is transferred to the magneto-optical disk device. The second page of the page area No. 13 is read out and sent to the image display device 4 via the magneto-optical interface 12t bus 81 and image display interface 3 for display (12), and then, while looking at the displayed heading page. The operator operates the keyboard 2 to select a page storing desired images and information (rs), followed by step (13).
The image information of the page selected is transferred to the magneto-optical disk device 1.
The data is read from the 30 page area and sent to the image display device 4 for display via the magneto-optical interface 2' and the bus 81 image display interface 3 (14).

Return to step (1).

Next, the image information reduction operation according to the present invention will be described with reference to FIGS. 4(a) and 4(b).

(a) of the same figure shows a video signal of a heading page related to item A, for example, which is written in the page memory 6, and (b) of the same figure shows a video signal of a large heading page written to the page memory 7. .

For example, if an attempt is made to compress 16 images into an area normally allocated to one image, the video signals of each row and nine columns for one image will be compressed to 1/4. Therefore, the video signals recorded in the page memory 6 are extracted at a rate of 1 bit for every 4 bits in the row direction in synchronization with a clock signal generated by a command from the CPU 3.
The video signal bit by bit is written in the row direction of the page memory 7 as shown in FIG. 4(b). By sequentially executing this operation in the column direction of the video signal recorded in the t-page memory 6, the image information can be compressed as shown in FIG. 2(c). Note that the image compression rate can be set arbitrarily by the operator.
