CONSTITUTION:A controller 2 turns selection switches 8a and 8b for page memory input to the side of a reduced picture by the operation of an operating part 1. Then the picture information on a designated file name is sent to a reduction means 6 from a memory part 3, and the reduced picture information is sent to a page memory 4. When the transfer of picture information is through with pages up to the last one, the keyword information on each page is also transferred to the memory 4 like the picture information. Then a key word is also displayed on a CRT5 together with the picture information.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an image file system that records predetermined image information on a recording medium and reproduces the image information on an image display device.

[Prior Art] A conventional image file system records predetermined image information on a disk-shaped, tape-shaped, or drum-shaped recording medium, and reproduces the image information as necessary on an image display device such as a CRT display. exist. Then, a plurality of pages of image information may be reduced and displayed on the image display device to perform a search.

In this case, even if desired image information is displayed on the display screen of the image display device, it is impossible to immediately know the keyword necessary to retrieve the image information from the storage unit. Therefore, in order to immediately know the keyword of the displayed image information, the image information must be displayed without being reduced in size, resulting in a problem that the search time becomes long.

[Object of the Invention] The present invention has been made by focusing on the above-mentioned problems of the conventional art. When multiple pages of image information are displayed in the same display area, a desired page out of the multiple pages is displayed. The object of the present invention is to provide an image file system that allows one to immediately know keywords corresponding to image information.

[Embodiments of the Invention] FIG. 2 is a diagram showing the appearance of an image file system to which the present invention is applied.

In this figure, a control unit IC for controlling this system, a reader IR for reading images, a storage device 3 for storing image information, etc., and a CRT display 5 for outputting images are provided. . Note that the reader IR is not directly related to the present invention, and will therefore be omitted from the following description.

FIG. 1 is a block diagram showing one embodiment of the present invention.

The operation section 1 is for giving manual input to the controller 2, and the storage section 3 is for storing image information and keywords, and is installed externally. Here, the keyword is a code corresponding to each image information page,
A set of image information (hereinafter referred to as a file)
It consists of a file name corresponding to the page name and a page name corresponding to each page.
It's also one of my favorites.

The CRT 5 displays image information and is installed outside.

The page memory 4 temporarily holds image information for one screen of the CRT 5, and the reduction means 6 stores image information obtained from the storage section 3 in order to display image information for multiple pages within the CRT screen. The image information for one page is reduced.

The character generator 7 converts the keyword code information obtained in the storage section 3 into a character.

The page memory selection switches 8a and 8b are switches for selecting, as information to be given to the page memory 4, reduced image information, keyword character information, or image information of a specific page that is not reduced. The switches 8a and 8b are actually gate-controlled switches, but are shown as shown in FIG. 1 to simplify the explanation.

The received image information is stored in a predetermined area (that is, a chart).

Here, an example will be explained in which only the file name in the keyword is known and a specific page is to be searched from within the file. Also, let us take as an example a case where a search is performed while simultaneously displaying nine pages of images on one screen of the CRT 5.

First, each of "search mode", "simultaneous display of 9 images", and "file name" is specified to the controller 3 from the operation unit 1. All subsequent sequences are automatically performed by the controller 2. The controller 2 turns the page memory input selection switches 8a and 8b to the reduced image side (that is, the R side in FIG. 2), and transfers the image information of the first page of the specified file name from the storage section 3 to the reduction section 6. Here, the data is reduced and sent to the page memory 4.

Prior to this, the controller 2 gives the page memory 4 information that the image is the first page, so the page memory 4 stores the image in the first page area.

Thereafter, under the control of the controller 2, the sequence from the second page to the ninth page is performed in the same manner as described above.

When the reduction of the image information up to the ninth page and the transfer to the page memory 4 are completed, the first
The keyword information from the page to the ninth page is transferred to the page memory 4 following the same process as the image information.

Then, each of the above-mentioned keyword information is held in an area in the page memory 4 corresponding to each page of the previously transferred image information. However, the numbers or alphanumeric characters input on the operation unit 1 when setting the keyword are held in the storage unit 3 in a coded state.

Since the page memory 4 is a part that stores only information that can be visualized directly, coded keyword information must be converted into characters as image information during transfer. The character generator 7 performs this conversion. That is, when transferring keyword information, the page memory input selection switches 8a and 8b are turned to the keyword input side (ie, to the side) under the control of the controller 2, and the keyword information passes through the character generator 7, so that the above conversion is performed. It is done.

Next, the operation of the reduction means will be explained.

FIG. 3 shows the internal configuration of the vertical reduction section within the reduction means.

The V I DEO signal and the H5YNC signal are an image signal and a horizontal synchronization signal sent from the storage section 3. In the above embodiment, the frequency dividing circuit 11 uses a % frequency dividing circuit. Furthermore, an AND circuit 12 is provided. The HSYNC' signal and the VIDEO' signal are an image signal that has passed through a vertical reduction section and a horizontal synchronization signal.

FIG. 4 is a diagram showing a series of signal waveforms in the main part of the embodiment shown in FIG.

First, by passing the H3YNC signal through the frequency divider circuit,
Can be changed to HSYNC' signal. The amount of information of the VIDEO' signal, which is input to the D-type flip-flop 22, is reduced to a signal, and the VIDEO' signal is obtained by multiplying the HSYNC' signal by the VIDEO signal. That is, the vertical reduction section shown in FIG. 3 reduces the HSYNC signal and the VIDEO signal by 3/ and 2, respectively, to become the HSYNC' signal and the VIDEO' signal.

FIG. 5 shows the horizontal reduction section in the reduction means, and FIG.
FIG. 6 is a diagram showing signal waveforms of main parts of FIG. 5;

In the case of the above embodiment, the frequency dividing circuit 21 is constituted by a frequency dividing circuit. A D-type flip-flop 22 is also provided. The VCLK signal is a video clock signal sent from the storage section 3. The V I DEO'' signal and the VCLK' signal are an image signal that has passed through the horizontal reduction section and a video clock signal.

First, the VCLK signal is frequency-divided into stations by the local frequency circuit 21, resulting in the VCLK' signal shown in FIG. This VCLK' signal is applied to the D-type flip-flop 2 in FIG.
2 clock, and there is.

R-Panme $ +1 A L+ Saiyun City Isao 1 page...maybe ryobor The waveform of the VIDEO"' signal as shown in FIG. 6 is output.

Note that the VIDEO'' signal shown in FIG. 6 is the same as the VIDEO' signal shown in FIG. 4, but the time axis (horizontal axis) is changed and the VIDEO' The signal is shown as an example.The D-type flip-flop 22 takes in data (VIDEO' signal) at the falling edge of the clock signal (VCLK' signal).

Since the clock signal (VCLK' signal) is reduced to a station, the VIDEO'' signal is a reduction of the VIDEO' signal to a station.

In the above-described manner, each signal passes through the reduction section 5, thereby reducing the image information in both the horizontal and vertical directions, so that the image size is similar to that of the image.

Next, page memory 4 will be explained.

Figure 7 is a diagram showing the internal configuration of page memory.
I'm so hungry, I'm so hungry
It is a memory that stores 11411% information. counter 3
'2゜33 is a counter that determines the write location in the page memory 4 for each pixel with respect to the image information sent to the page memory 4, the horizontal counter 32 is a counter in the horizontal direction, and the vertical counter 33 is in the vertical direction. It determines the position of

The VSYNC signal is a synchronization signal sent from the storage unit 3, and the image information for one page in the storage unit 3 is transmitted by this VSYNC signal.
It is transferred in synchronization with the NC signal.

The H preset signal and the V preset signal are signals indicating the values when the horizontal counter 32 and the vertical counter 33 are cleared, that is, the preset values, respectively.
This is determined by the controller 2 for each page of image information.

The CHARACT signal is character image information that is the output of the character generator 7. Write command WR
The read command RD is a command signal given from the controller 2 to the page memory 4.

V I DEO'''' is display image information output from the page memory 4 in response to the read command RD.

Here, an example will be described in which a reduced image of the fifth page in one display image is written to the page memory 4.

First, the controller 2 recognizes that it is the 5th page, and sends the H preset signal and ■ preset signal to the 7th page.
Set to H and V shown in the figure. Next, writing of the reduced image of the fifth page is started in synchronization with the VSYNC signal. At this time, the horizontal counter 32 changes from the initial value H to VC.
Each time information is written for l pixel in synchronization with the LK' signal, 1 is added from the initial value, and when the value of the VCLK' signal corresponding to one horizontal scan of the reduced image (station before reduction) is reached, the vertical Adds 1 to the counter 33, resets itself, and
Return to the value of The vertical counter 33 completes writing of the fifth page reduced image in area I when the H3YNC' signal reaches a value corresponding to the vertical direction of the reduced image (station before reduction).

In this manner, writing of reduced images from the first page to the ninth page in one display image is completed.

Next, keyword characters are written in a similar manner. However, for example, in the case of writing a character corresponding to the reduced image on the fifth page, the value of the H preset signal is H in FIG. V of
is set to i. Further, since the character generator 7 generates a character whose vertical direction is between Vi and V' in FIG. 7, character information is written in the area C in FIG.

Through the process described above, the characters of the respective keywords corresponding to the reduced image pages 1 to 9 are written.

When the writing to the page memory 4 is completed as described above, the read command RD is given from the controller 2, and the entire page memory 4 is read out. That is, one horizontal scan is read from O to HO in FIG. 7, and vertically from O to VO in FIG. When this output is displayed on a CRT, a display as shown in FIG. 8 is obtained. Further, this output display may be performed by a display device using electrophotographic technology or the like.

The above process corresponds to pages 10 to 18 in the file.
The search can be continued in the same manner as the page, and then the 19th page to the 27th page.

If a desired page appears on the display screen during the search, the keyword associated with that page is input from the operation unit 1 along with the file name and page name, as shown in FIG. As a result, the controller 2
The page memory input selection switch 8 is turned to the specific page side (that is, the S side), and one page of image information corresponding to the keyword specified in the storage section 3 is outputted.

Since this image information is sent to the page memory section 4 without passing through the reduction means 6, the entire area of the page memory 4 is
Image information for the page is written. By displaying this in the same manner as above, the required image can be obtained without being reduced.

FIG. 9 is a flowchart showing the overall operation of the above embodiment.

First, D indicating which screen the display image is on is initialized (St), and it is determined whether a keyword is to be input (S2). When inputting a keyword, move the page memory input selection switches 8a and 8b to the specific page side (S
(S3) and instructs the storage unit 3 to transfer the image information of the □ page corresponding to the keyword (S4). Then, the contents of the page memory 4 are displayed on the display (S5), and the process ends (S6).

If a keyword is not input (S2), it is determined whether or not to instruct a search (S10), and the page memory input selection switches 8a and 8b are set to the reduced image side (R side) (Sll), Set N, which indicates the number of pages in one screen, to 1, substitute the calculation result of 9 * D + N to K (312), and set the H preset value and V preset value to the value of the Nth page.S 13),
Commands the storage unit 3 to transfer the image information of the page (S
14).

Then, image information for 9 pages is transferred within one screen (
S 15 , 316). After transferring the image information for 9 pages, set the page memory input selection switches 8a and 8b to the keyword side (K side) 517), increase K by 1 (318), set the H preset value and Set the T value to the value of "Keyword Nth page" S 19
), command to transfer the keyword data of the Kth page 5
20), the transfer of the j-2 keyword data is repeated up to nine pages (S22). After transferring nine pages of keyword data, the contents of the page memory 4 are displayed on the display (530), 1 is added to the above value, and the process returns to S2.

[Effects of the Invention] According to the present invention, when displaying image information for a plurality of pages in the same display area, it is possible to immediately know the keyword corresponding to the image information of a desired page among the plurality of pages. This has the effect of shortening search time.
