Abstract

PURPOSE:To facilitate the easy designation of pictures by using a keyword designating means to designate plural corresponding key words out of the displayed pictures while the pictures equivalent to plural pages are displayed at a time. 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 plural pages of a designated file name and a keyword are sent to a reducing means 6 from a memory part 3. The reduced picture information and the keyword are sent to a page memory 4 and displayed on a CRT5. When a desired page is displayed in a retrieval mode on the CRT5, the keyword of said page is supplied through the part 1. Thus both switches 8a and 8b are changed to the (s) side. Then the picture information on the designated page is sent directly to the memory 4 from the part 3 and displayed on the CRT5.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an image processing 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 processing system records predetermined image information on a recording medium such as a disk, tape, or drum, 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 the above-mentioned conventional device, when a plurality of desired images are displayed on the display screen of the image display device, when displaying the images at the same size, etc., the operation of pulling out the plurality of image information from the storage unit is complicated. There is a problem that.

That is, in the above case, first, specify the keyword corresponding to the first image among the desired images, clear the screen, display the above screen again, and select the second image from the displayed screen. Specify the keyword corresponding to the second image. If there are three or more desired images, the above operation is repeated as many times as necessary. In this way, only one image can be designated on one screen, so when multiple images are designated on the same screen, the designation operation becomes complicated.

[Purpose of the Invention] The present invention has been made in view of the above-mentioned conventional problems, and it is possible to easily perform the specification operation when specifying images for multiple pages displayed on the same screen. The purpose is to provide an image processing system that can.

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

In this figure, a control unit IC for controlling the 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 , and a page name corresponding to each page. 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.

Next, the operation of the above embodiment will be explained.

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

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 sent image information in a predetermined area (
In other words, it is held 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 (that is, to the side) under the control of the controller 2, and the keyword information is passed through the character generator 7. A conversion takes place.

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 H3YNC signal are an image signal and a horizontal synchronization signal sent from the storage section 3, respectively. In the above embodiment, the frequency dividing circuit 11 uses a local frequency circuit. Furthermore, an AND circuit 12 is provided. The H3YNC' 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 signal waveforms in essential parts of the embodiment shown in FIG.

First, when the H3YNC signal passes through the local oscillator circuit,
It can be changed to H3YNC' signal. By multiplying this H3YNC' signal and the VIDEO signal, VIDE
An O' signal is obtained. That is, the vertical reduction section shown in FIG.
It becomes a 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 an attribute frequency circuit. Further, a DJJ flip-flop 22 is provided. The VCLK signal is a video clock signal sent from the storage section 3. The V I D E O'' 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, the information amount of the VIDEO' signal which is the input of the D-type flip-flop 22 is reduced to reach the 6th clock.
The waveform of the V I D E O" signal as shown in the figure 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.

The VIDEO' signal in FIG. 6 shows an example of this. Further, the D-type flip-flop 22 receives a clock signal (VC
The data (VIDEO' signal) is taken in at the falling edge of the LK' signal.

Then, since the clock signal (VCLK' signal) is reduced to within reach, the VIDEO' signal becomes VIDE.
This means that the O' signal has been reduced to within reach.

As described above, when each signal passes through the reduction unit 5, the image information is reduced in both the horizontal and vertical directions, and the image size is similar to that of the image.

Next, page memory 4 will be explained.

FIG. 7 is a diagram showing the internal configuration of the page memory.

The page memory 4 is a memory that stores image information for one page of display images. The counters 32 and 33 count the image information sent to the page memory 4.
This is a counter that determines the write location for each pixel within the frame, and the horizontal counter 32 determines the position in the horizontal direction, and the vertical counter 33 determines the position in the vertical direction.

The VSYNC signal is a synchronization signal sent from the storage unit 3, and the information on both images for one page in the storage unit 3 is transmitted from 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.

VIDEO"' 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 V 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 one pixel in synchronization with the LK' signal, 1 is added from the initial value, and when it reaches the value of the VCLK' signal (the value before reduction) corresponding to one horizontal scan of the reduced image,
Adds 1 to the vertical counter 33, resets itself,
Return to H value. When the vertical counter 33 continues writing until the H3YNC' signal reaches a value corresponding to the vertical direction of the reduced image (station before reduction), writing of the reduced image of the 5th page is completed in the area processing.

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. Also, since the character generator 7 is to generate 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 writing to the page memory 4 is completed as described above, a 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.

A plurality of images corresponding to a specified file name are displayed on the same display screen, and an operation for specifying a desired image from among the displayed images will be described.

First, instruct the search mode from the operation unit 1 (Sl).
, input the file name to be searched (S2). and,
The controller 2 calls each piece of image data corresponding to the file name to be searched from the storage unit 3, and the reduction means 6 displays a reduced image of the image data on the CRT 5 (S3
).

The user uses the operation unit 1 to specify a desired image from among the reduced display images. In this case, the image specification is
Enter the keyword corresponding to the image (S4
). The keywords are ordered in the order in which they are input (S5). For example, if a keyword is entered first, the order is "1", if a keyword is entered second, the order is "2", and so on.

When the keyword specification is completed (S6), it is determined whether or not to display the image corresponding to the specified keyword (S7). If an image of a specified keyword is specified to be displayed, the controller 2 stores the image data corresponding to the first keyword in the storage unit 3.
The above image data is visualized on the CRT 5 (S8). After the processing of the first display image is finished, if you want to visualize the image of the next keyword (second) (S9), give that designation from the operation panel l and display the image corresponding to that keyword. do (s io).

By doing this, when instructing to display images corresponding to the first or second keyword, the keyword corresponding to each image is
There is no need to give instructions every time an image is displayed. This changes the input order of keywords corresponding to searched images on the controller 1.
This is because the image display is always recognized, and each time an image display instruction is input, the image is output in accordance with the input order. Then, when all images corresponding to the searched keyword are displayed (S11), the series of search operations is completed (S12).

Note that the order in which images desired to be displayed may be specified may be different from the order in which those images are displayed. That is, for example, the first designated image may be displayed second, and the second designated image may be displayed first.

[Effects of the Invention] According to the present invention, when specifying images for a plurality of pages displayed on the same screen, the specifying operation can be easily performed.
