Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image retrieval device,
More specifically, the present invention relates to an image search apparatus that controls a display unit so that a predetermined image is displayed on one screen of the display unit to perform an image search.

[0002]

2. Description of the Related Art In recent years, each page of a document including a large number of pages is read by a scanner, and the image data of the read page is stored on an optical disk together with an index such as a document name, a classification name, a keyword corresponding to the document. An image retrieval device that does this has been proposed. When searching for desired image data from the image data stored on the optical disk in such an image search device, first, the stored image data is first searched based on the index described above. When searched in this way, an image data group (document) made up of a plurality of image data including desired image data is obtained as a candidate for the desired image data. Then, the screen of the CRT display device or the like is switched so that the obtained plurality of image data are sequentially and continuously displayed at high speed (hereinafter, referred to as page turning search). And
After confirming the desired page, the operator issues a command to stop the page turning search to stop switching the screen of the CRT display device or the like.

For such a page turning search,
Furthermore, the following search methods have been proposed. That is, the operator selects a desired document from the reduced image group in which the thickness of the document group (the number of documents) is known, specifies the vicinity of the desired page from the thickness, and sequentially performs the page-turning search from that point. A method of doing so has been proposed (JP-A-63-2).
No. 4361).

Further, page designation information (for example, the first page) for designating pages of a plurality of documents is stored in advance, and only the images of the designated page (for example, the first page) are stored. A method has been proposed in which a page-by-page search is sequentially performed (Japanese Patent Laid-Open No. 2-230375).

Further, search information (file name, keyword, number of pages, corresponding to image data of each page of the document,
(Consisting of an address) is stored in advance on a magnetic disk, and when a desired document image-like thing is displayed and an operator inputs a command to store the search information during the image search, the search information is stored in the memory. . This is repeated until the image data of all pages are read from the optical disc and displayed. Then, when the operator gives an instruction to continue the search, a method has been proposed in which, based on the search information stored in the memory, only the image of the page corresponding to the search information is read out from the optical disc and displayed (Japanese Patent Laid-Open No. HEI 2). 105257).

[0006]

However, in the prior art, the operator selects a desired document and designates the vicinity of the desired page based on the thickness thereof, or designates pages of a plurality of document groups, The operator's burden was heavy, such as inputting a command to store search information.

The present invention has been made in view of the above facts, and an object of the present invention is to provide an image retrieval apparatus capable of reducing the burden on the operator and displaying a desired image quickly.

[0008]

In order to achieve the above-mentioned object, the invention according to claim 1 is to display means for displaying a predetermined image on one screen, the number of accesses per screen of the display means, and 1
Storage means for storing data representing at least one of display times for each screen as history data, and priority order of images displayed on the display means are determined based on the history data stored in the storage means, and determined. Control means for controlling the display means so that images are displayed in priority order.

According to a second aspect of the present invention, in the first aspect of the invention, the control means determines the order in which the product of the access count and the display time is the largest as the priority order.

According to a third aspect of the present invention, in the first or second aspect of the present invention, the history data which has been stored in the storage means for a predetermined time or more has been deleted.

According to a fourth aspect of the present invention, in the invention according to any one of the first to third aspects, the display time is a display time per access.

According to a fifth aspect of the present invention, in the invention according to any one of the first to fourth aspects, the storage means stores history data for each operator.

[0013]

According to the first aspect of the invention, the display means displays a predetermined image on one screen, and the storage means stores data representing at least one of the number of access times and the display time for each screen of the display means. Is stored as history data.

Here, the control means determines the priority order of the images to be displayed on the display means based on the history data stored in the storage means. That is, the factor that determines the priority order of the images is any one of the number of accesses per screen, the display time of one screen, the number of accesses per screen, and the display time of one screen. Then, the display unit is controlled so that the images are displayed in the determined priority order.

Here, the number of times of access for each screen corresponds to the frequency of use of the image. Therefore, when the priority order is determined based on the number of times of access for each screen, the priority order is determined according to the frequency of use of images, that is, the priority order is determined in descending order of frequency of use of images, Will be displayed. The display time for each screen corresponds to the display time of the accessed image. Therefore, when the priority order is determined based on the display time for each screen, the priority order is determined corresponding to the display time of the accessed image, that is, the display time of the accessed image is determined in descending order. Will display the images in the order of length.

By the way, the accessed image may have a short display time even if the accessed number is large, and the accessed image may have a long display time at least. Therefore, as in the invention described in claim 2, if the order of the product of the number of times of access to each screen of the display means and the display time of each screen is larger is the priority order of the images displayed on the display means, the access is performed. Since the product of the number of times and the display time for each image corresponds to the importance of the image to the operator, the order of the importance of the images becomes the priority order of the images displayed on the display means, and the images targeted by the operator are searched. Is more likely to be displayed, and a desired image can be displayed quickly.

As described above, the invention according to claim 1 displays on the display means based on the history data which is at least one of the number of times of access of each screen of the display means and the display time of each screen. Since the priority order of the images is determined, it is possible to eliminate the operator's burden such as specifying the image to be displayed, reduce the operator's burden, and use the priority order determined based on the history data. Since the display means is controlled so that the image is displayed, there is a high possibility that the image targeted by the operator will be displayed, and the desired image can be displayed quickly.

According to the third aspect of the present invention, the history data which is stored in the storage means according to the first or second aspect for a predetermined time or more has been deleted.

As described above, since the history data that has been stored for a predetermined time or more since the history data is stored is deleted, the number of access times for each screen for which the image search is performed from the time when the image search is performed to the predetermined time before. And the priority order of the images displayed on the display means is determined based on at least one of the display time for each screen, and the priority order of the images is determined based on the latest history data. The images are displayed in the order of priority determined based on, and the desired image can be displayed quickly.

In the invention according to claim 4, the display time according to any one of claims 1 to 3 is a display time per access.

As described above, since the display time of the history data is set as the display time per access, for example, the display time of the image displayed in one image search is longer than the display time in another image search. However, the error can be reduced, and the operator is more likely to display an image close to the desired image, and the desired image can be displayed quickly.

According to a fifth aspect of the present invention, in the invention according to any one of the first to fourth aspects, the history data for each operator is stored in the storage means.

As described above, since the history data corresponds to the operator, a desired image can be quickly displayed for each operator and the burden on the operator can be reduced.

The keyboard 18 is for inputting a pointer of image data to be stored in an optical disk, which will be described later, a personal ID for identifying an operator and various instructions for processing such as storage and editing. The instructions for processing such as storage and editing are input by selecting the storage mode, the editing mode, or the like.

The mouse 20, for example, moves a cursor (not shown) displayed on the screen of the display 36, which will be described later, and gives an instruction at a desired position to select and instruct the command or the like at which the cursor is located. Is.

The image retrieval device also includes an optical disk controller 22, an optical disk 24, a magnetic disk controller 26 and a magnetic disk 28.

The optical disk controller 22 stores the image data input from the scanner 16 in the optical disk 24, and also reads the image data corresponding to the index input from the keyboard 18 from the image data stored in the optical disk 24.

The magnetic disk controller 26 stores the pointer, history data and individual ID corresponding to the individual ID in the magnetic disk 28. The pointer and history data corresponding to the personal ID will be described later.

Further, the image retrieval apparatus comprises a VRAM (video RAM) 30, a compression / expansion processor 32, a display controller 34 and a display 36.

The VRAM 30 stores the display image developed as image data. Compression / expansion processor 3
Reference numeral 2 has a compression / expansion circuit that performs encoding processing for performing image compression and decompression, a scaling circuit that performs image enlargement and reduction processing, and a vertical-horizontal conversion circuit that performs image rotation processing. Here, the compression / expansion circuit uses the MH (Modif
ied Huffman) method or MR (Modi)
Band compression or band expansion is performed using the fied read method.

The display controller (for example, cathode ray tube display device) 34 displays an image on the display 36 based on the image data read by the scanner 16 and the image data read from the optical disk 24 to form a screen. Here, on the screen of the display 36, as shown in FIG. 2, a region 36A in which an image is displayed and a mouse 2 are displayed.
An area 36B for displaying key buttons for moving the cursor by 0 to specify various processes is provided. An image for one page is displayed in the area 36A.
In this embodiment, the image for one page is displayed in the area 36A, but the present invention is not limited to this. For example, two pages, three pages, ... Good. In the area 36B, a start button 36B1 for instructing a command for image search processing (start command), a stop button 36B2 for instructing a command for stopping image search processing (stop command), and a command for ending image search processing (end). An end button 36B3 for instructing a (command) is displayed.

The various components of the image retrieval apparatus described above are electrically connected via a bus (including an address bus, a data bus, a control bus) 38.

Next, the pointer and history data corresponding to the personal ID stored in the magnetic disk 28 will be described with reference to FIGS. 3 and 4. In FIG. 3, the magnetic disk 2
The pointer table 28A stored in FIG. As shown in FIG. 3, in the pointer table 28A, the pointers to the image data previously searched by the operator are stored as a table corresponding to the personal ID as an identifier for identifying the operator. There is.
The personal IDs are User1, User2, and Us.
er3, ... Are used. For example, if the operator whose personal ID is identified as User1 previously searched for the image of the document whose pointers were identified as book1 to book5, the pointers book1 to book5 that identify the image data group of the document corresponded to User1. Remembered. In this way, the pointer table 28 stores pointers for identifying the document images previously searched by the operator, corresponding to the individual IDs of the operators. The personal IDs are User1, User2, and Us.
It is not limited to er3, ..., For example, it may be the name of the operator. Also, the pointer is boo
It is not limited to k1, book2, book3, ..., As long as it uniquely represents the image data group of the document, it may be, for example, an address stored in the optical disc 24. In this way, the pointer table 28A
With reference to, it is possible to know the image data previously retrieved for each operator. Then, history data for each operator can be read based on the pointer.

Next, the history data stored in the magnetic disk 28 will be described. In FIG. 4, a history data table 28 for each page of the image (pointer is book1) of the document previously searched by the operator identified as User1.
B is shown. As shown in FIG. 4, the history data table 28B stores a table of stop frequencies, average display times, and evaluation values for each page ID that identifies each page.

Here, the stop frequency means the display 36.
This is the number of times the image displayed on the screen is accessed, and the number of times the stop button 36B2 was pressed during the image search. In addition,
The stop frequency is reset for a predetermined time, for example, every week or every month. As a result, it is possible to recognize a page that has been frequently referred to recently. This process will be described later.

The average display time means the display 3
6 is the display time of the image displayed in 6, and the stop button 3 is the time from the time the stop button 36B2 is pressed during the image search to the time the next start button 36B1 is pressed.
6B2 is the display time per press. Note that the average display time is such an error amount when the display time during which a desired image is displayed during a certain image search is longer than the permissible range than the time during which another image is searched. This is to reduce the number. The time from when the stop command is pressed until when the next start command is pressed is measured by a timer function (soft timer) (not shown) in the image retrieval apparatus. Since the average display time is the display time per one time when the stop button 36B2 is pressed, it is not periodically reset.

The evaluation value is a value indicating the importance of the page to the operator. That is, if the average display time is short and the stop frequency is high, or if the average stop time is low and the average display time is long, the page is important to the operator. Therefore, the evaluation value is a product of the stop frequency and the average display time.

In this way, page I for identifying each page
The history data table 28B in which the stop frequency, the average display time, and the evaluation value for each D are tables is stored in the magnetic disk 28 for each pointer and for each operator.

Next, the operation of this embodiment will be described. First,
The operation of the image search device when performing the process of storing image data will be described. The storage mode is selected and set by the keyboard 18, and the index of the image data stored in the optical disk 24 is input. Next, the manuscript (one page of the document) is set on the scanner 16, and the optical disk controller 26,
The display controller 34 and the scanner controller 14 are operated. The scanner controller 14 drives the scanner 16 to two-dimensionally scan the image of the set page to perform photoelectric conversion. The line information (image data) for each line of the photoelectrically converted image is stored in the VRAM.
Sequentially store in 30. The VRAM 30 outputs the image data for one page to the display controller 34 when the image table for one page is stored. The display controller 34 outputs 1 output from the VRAM 30.
An image of one page is displayed on the display 36 based on the image data of the page to form a screen.

Here, the operator confirms the skew, density, resolution, etc. of the displayed image, and if the displayed image is satisfactory, selects the storage mode of the keyboard 18 and the VRAM 30. The image data stored in is input to the compression / expansion processor 32 line by line. The compression / expansion circuit encodes the input image data for each line. Then, the encoded image data is stored in the optical disc by the optical disc controller 22.

Next, the image search processing of the image search apparatus will be described with reference to the flowchart shown in FIG.

When the operator has a personal ID (for example, User
When you enter 1), the image search process starts and Step 4
1, reset the timer function. In step 42,
The history data is read out. That is, as shown in FIG. 6, the history data management unit 80 uses the input personal I
D is output to the magnetic disk controller 26. The magnetic disk controller 26 reads the pointer corresponding to the personal ID from the pointer table 28A based on the input personal ID. Thereafter, the magnetic disk controller 26 sets the evaluation value of the history data to the history data table 2 based on the input personal ID and the read pointer.
Read from 8B. Then, the magnetic disk controller 26 outputs the read evaluation value to the history data management unit 80. The history data management unit 80 outputs the input evaluation value to the display order determination unit 82. In this way, step 41
And the step 42 is performed by the history data management unit 80.

In step 43, page display order determination processing is performed based on the read history data. That is,
The display order determination unit 82 that has input the evaluation value determines the display order (priority order) of the pages for each document identified by each pointer based on the following rules. The page IDs are arranged in the descending order of evaluation value. If the evaluation values are the same, the display order is determined from the page with the lowest page ID. Note that the page that has not been stopped even once has an evaluation value of 0, but if there are multiple pages with an evaluation value of 0, there are multiple pages with the same evaluation value, so the page ID is low. Determine the display order from the ones. Then, the display order determination unit 82 outputs the page IDs arranged based on the above rules to the image display unit 84.

As described above, the page ID is based on the evaluation value.
After the page display order is determined by arranging
The image display unit 84 waits until a command is input in step 44, and if the command is input, the image display portion 84 executes step 4
In step 5, it is determined whether the input command is a start command. If it is not a start command, the process returns to step 44 and waits until another command is input.

On the other hand, when the start command is input, in step 46, display processing of the image data is performed in the determined order. That is, the image display unit 84 outputs the page IDs to the optical disc controller 22 in the order of the page IDs arranged based on the evaluation value input from the display order determination unit 82. The optical disc controller 22 reads the image data for each line of the page from the optical disc 24 based on the input page ID and supplies it to the compression / expansion circuit of the compression / expansion processor 32. The compression / expansion circuit expands the band of the input image data and sequentially outputs VR data.
Supply to AM30. The VRAM 30 supplies the image data for one page to the display controller 34 when the image data for one page is stored.

As a result, the display controller 3
4 displays an image of one page on the display 36.
Then, the image of the one page is displayed for a predetermined time, for example, 0.5
Display for [sec].

When this predetermined time has elapsed, step 47
Then, it is determined whether or not the command is input. When it is determined that the command has not been input, the process returns to step 46, and the screen of the display 36 is switched so that the image of the next page in the determined order is displayed.
On the other hand, when the command is input, step 48
Then, it is determined whether the input command is a stop command. That is, when an image desired by the operator is displayed on the display 36 and the operator presses the stop button 36B2 to input a stop command, in step 49, the image display unit 84 (see FIG. 6): The page ID of the page displayed on the display 36 when the stop button 36B2 is pressed is output to the history data measuring unit 86.

Steps 44 to 49 described above
The image display unit 84 performs the processing up to.

In step 50, the history data measuring unit 86 drives the timer function described above. Step 51
Then, it is determined whether or not a new command is input. If a new command is input, it is determined at step 52 whether or not the input command is a start command,
If it is not the start command, the process returns to step 51 and waits until the command is input again. On the other hand, when the start button 36B1 is pressed and the start command is input, in step 53, the history data measuring unit 86
Stops the driving of the timer function described above. Then, in step 54, the latest history data (image display unit 8
4. The stop button 36 input from 4 and the stop button 36 measured by the timer function and the page ID of the page displayed on the display 36 when the stop button 36B2 is pressed.
The time from when B2 is pressed to when the start button 36B1 is pressed) is output to the history data management unit 80.
The history data measuring unit 86 performs the processing from step 50 to step 54 described above.

In step 55, history data update processing is performed. That is, in the history data management unit 80, step 5
In step 4, the latest history data input from the history data measuring unit 86 is output to the magnetic disk controller 26. That is, the history data management unit 80 outputs the page ID to the magnetic disk controller 26. The magnetic disk controller 26 increments the value of the stop frequency of the history data table 28B by 1 based on the input page ID. Further, the history data management unit 80 outputs to the magnetic disk controller 26 the time from when the stop button 36B2 is pressed until when the start button 36B1 is pressed. The magnetic disk controller 26 adds the input time to the evaluation value of the history data table 28B, and stores a value obtained by averaging the added value with the stop frequency incremented by 1 as a new average display time. Then, the value obtained by multiplying the new stop frequency and the new average display time is stored as a new evaluation value. The time at which the history data is updated is also output to the magnetic disk controller 26 and stored in the magnetic disk 28 together with the history data. The time at which the history data is updated is measured by a soft timer other than the above-described soft timer (not shown) in the image search apparatus. Hardware having a clock function other than the soft timer may be used.

When the update process of the history data is completed in this way, the process returns to step 46 and the display process of the image data of the page ID next to the page ID arranged based on the above-mentioned evaluation value is performed. Then, when it is determined in step 48 that the input command is not the stop command by performing the processing of steps 47 and 48, it is determined in step 56 that the end button 36B3 has been pressed and the end command has been input. To determine. If it is not the end command, the process returns to step 46 to perform the image data display processing again, and if the end command is input,
This process ends.

As described above, since the page images are displayed in the order determined based on the evaluation value which is the product of the stop frequency and the average display time, the page images are displayed in descending order of importance to the operator. Since the image is displayed, there is a high possibility that the image data targeted by the operator's search will be displayed, and the desired page can be searched quickly.

Further, in the above-described embodiment, since the image search is performed only by the operator inputting the personal ID, it is possible to eliminate the processing such as designation of the search page, and the labor of the operator can be remarkably reduced. it can.

Next, the process of resetting the stop frequency of the history data will be described with reference to the flow chart shown in FIG. Note that this process is repeatedly executed for a predetermined time, for example, every week.

In step 92, a variable i representing the personal ID (User), a variable j representing the pointer (book), and a variable k representing the page ID are initialized to 0, and in step 94,
The variable i is incremented by 1, and in step 96, the variable j
Is incremented by 1, and in step 98, the variable k is incremented by 1. As a result, the page ID of bookj, which is the pointer stored in association with Useri, is k.
(K page) is selected.

At step 100, the update time of the history data stored in correspondence with the history data whose page ID of bookj stored in correspondence with Useri is k is read out. In step 102, whether the read history data is updated at a predetermined time, for example, one week or more, from the current time,
That is, it is determined whether or not one week has already passed since the history data was updated. If one week has already passed since the update, the stop frequency of the history data is set to 0 in step 104. Then, in step 106, the evaluation value is set to 0, and the process proceeds to step 108. If one week has not yet passed since the history data was updated, the process proceeds to step 108.

In step 108, the variable k is bookj
If the variable k is not equal to or larger than K, it is determined whether or not it is a bookj.
Since the reset processing of the stop frequency of the history data of all pages of the document identified by is not completed, step 98
Then, the above processing (step 98 to step 10)
Perform 8).

On the other hand, when the variable k is K or more, b
Since the process of resetting the stop frequency of the history data has been completed up to the last page of the document identified by ookj, in step 110, is the variable j equal to or greater than the number J of all pointers stored corresponding to Useri? If the variable j is not greater than or equal to J, the reset processing of the stop frequency of the history data of all pointers stored corresponding to Useri has not been completed, and thus the variable k is set to 0 in step 112. After initialization, the process returns to step 96 and the above processing (step 96 to step 110) is performed.

On the other hand, when the variable j is J or more, U
Since the reset processing of the stop frequency of the history data of all the pointers stored corresponding to seri is completed, it is determined in step 114 whether the variable i is equal to or more than the number I of all operators, and the variable i But the number of all operators I
If not, the process of resetting the stop frequency of the history data stored corresponding to the personal IDs of all the operators has not been completed.
Is initialized to 0, the process returns to step 94, and the above processing (steps 94 to 114) is performed.

On the other hand, when the variable i is equal to or more than the number I of all operators, the reset processing of the stop frequency of the history data stored corresponding to the personal IDs of all the operators is completed, so this processing is executed. finish.

In this way, since the stop frequency of history data that has passed a predetermined time or more since the history data was updated is reset, a large number of searches were performed for each operator before, but recently (for example, one week). The evaluation value of a page that has not been searched becomes 0, and the history data can be updated according to the operator's search status. At the time of the image search processing described above, images are searched based on this evaluation value.
The possibility of displaying from the image that is the target of the operator's search increases. Also, by looking at the stop frequency, it is possible for each operator to recognize which page has been searched a lot recently.

Here, only the stop frequency is reset, but the present invention is not limited to this, and the average display time may be reset. In the above-described embodiment, the evaluation value is the product of the stop frequency and the average evaluation value,
If only the stop frequency is reset, the latest evaluation value according to the search situation can be obtained for each operator, so only the stop frequency is reset.

Further, in the above-mentioned embodiment, the history data (stop frequency and evaluation value) which has not been searched for one week or more is reset, but the present invention is not limited to this.
It may be 2 weeks, 3 weeks, 1 month, 2 months ... It should be noted that the routine shown in FIG. 7 is repeatedly executed every time corresponding to this.

In the embodiment described above, the display order of the image data is determined based on the evaluation value which is the product of the stop frequency and the average display time, but the present invention is not limited to this. It may be determined based on any of the average display times.

Further, in the above-mentioned embodiment, the stop frequency is
The resetting is performed every predetermined time, but the present invention is not limited to this, and the resetting frequency may not be reset, but may be simply the total stop frequency. Further, the average display time is the display time per access (a value obtained by averaging the total of a plurality of display times for displaying a page by the stop frequency), but the present invention is not limited to this, and the page is simply displayed. It may be the total of the displayed time. Further, the product of the stop frequency and the average display time is also stored in the history data table, but the present invention is not limited to this, and the stop frequency and the average display time are stored in the history data table, and the evaluation value is Alternatively, it may be calculated when the display order is determined.

As described above, the invention according to claim 1 is based on the history data which is at least one of the number of times of access for each image and the display time for each image displayed on the display means. Since the priority order of the images to be displayed on the screen is determined, the burden on the operator such as designating the images to be displayed can be eliminated, the burden on the operator can be reduced, and it is determined based on the history data. Since the screens of the display means are switched so that the images are displayed in the priority order, there is a high possibility that the image targeted by the operator is displayed, and the desired image can be displayed quickly. Have.

According to the second aspect of the present invention, the data representing the product of the number of accesses and the display time for each image corresponds to the importance of the image to the operator, and is displayed on the display means corresponding to the importance of the image. Since the priority order of the images is determined, it is possible to reduce the burden on the operator and to quickly display a desired image.

According to the third aspect of the present invention, since the history data that has been stored for a predetermined time or more after the history data is stored is deleted, one screen image is searched from the time when the image is searched to the time when the image is searched. The priority order of the images displayed on the display means is determined based on at least one of the number of times of access for each screen and the display time for each screen, and the priority order of the images is determined based on the latest history data. Images are displayed in the order of priority determined based on the latest history data,
This has an effect that a desired image can be displayed quickly.

According to the fourth aspect of the present invention, the display time of the history data is set as the display time for each access. Therefore, for example, the display time of the image displayed during a certain image search is compared to the time displayed during another image search. Even if it is longer than the display time, there is an effect that the error can be reduced, the possibility that the image targeted by the operator's search will be displayed, and the desired image can be displayed quickly. .

According to the invention of claim 5, since the history data corresponds to the operator, it is possible to quickly display a desired image for each operator and reduce the burden on the operator. Have.
