Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image recording apparatus and an image display apparatus suitable for use in an electronic filing apparatus for recording, reproducing and displaying an image of a standard document such as A4 or B5. .

[0002]

2. Description of the Related Art In recent years, as the amount of documents such as documents, materials, and reports handled in offices has increased, an electronic filing device for electronically filing and managing documents has been used for paperless and space saving. It has become possible to be.

In this electronic filing apparatus, for example, a standard document such as A4 or B5 is converted into image data by an image scanner or the like and is associated with an ID code for identifying (discriminating) the document, such as a magneto-optical disk. Can be recorded as a database (electronic filing) on the recording medium. Then, when a predetermined ID code is designated, a document (image data) corresponding to the ID code is read (retrieved) from the magneto-optical disk and displayed on a CRT or the like.
It will be printed out.

[0004]

[Problems to be Solved by the Invention] By the way, A4 and B5
For standard documents such as those that are used vertically
Some are used horizontally. Further, for example, there is an image scanner dedicated to a vertically placed document. When capturing an image of a horizontally placed document with such an image scanner, the horizontally placed document is set vertically and set in the image scanner. The image is read and recorded on the magneto-optical disk. In this way, the image of the document recorded on the magneto-optical disk is searched and read out,
When displayed on a CRT, the image of a horizontally placed document is displayed vertically, which is difficult to see.

Therefore, in such a case, there is a method of rotating the CRT so that the horizontally placed document is viewed sideways. However, since the CRT must be rotated every time the horizontally placed document is displayed, the user is required to rotate. There was a problem that made me feel annoyed.

In such a case, there is a method in which the image itself is rotated so that the image of a horizontally placed document displayed vertically is displayed horizontally. That is, as shown in the flowchart of FIG. 14, first, in step S41, the image data of the document recorded on the magneto-optical disk is searched,
In step S42, the image data is read, and the process proceeds to step S43. In step S43,
The image corresponding to the image data is displayed in the orientation read by the image scanner, that is, it is displayed vertically, for example, regardless of whether the document is placed vertically or horizontally, and the process proceeds to step S44 and the image displayed at step S43 is displayed. The user visually determines whether the document is vertically placed or horizontally placed. Step S44
In step S43, if the image displayed in step S43 is determined to be a vertically placed document, steps S45 and S46 are skipped and the process ends.

In step S44, step S43
If it is determined that the image displayed in step 3 is a horizontal document, the process proceeds to step S45, the image data is rearranged so as to rotate the image displayed in step S43 by 90 degrees, and the process proceeds to step S46. move on. In step S46, the image corresponding to the image data rearranged in step S45 is displayed, and the process ends.

However, this method not only takes time to rearrange the image data, but also requires the user to visually check each time the image is displayed, which causes the user to feel annoyed. was there.

Therefore, there is an image scanner capable of reading the image even if the document is set vertically or horizontally. However, when a document in which vertical pages and horizontal pages are mixed is set vertically, and the image is read by such an image scanner, the image of the horizontal pages is vertically displayed on the CRT. When the document is displayed, the document is set horizontally, and the image is read by such an image scanner, the image of a vertically placed page is displayed horizontally on the CRT, which is difficult to see.

The present invention has been made in view of such a situation, and it is possible to display an image of a document in an easy-to-see manner.

The print data output from the AM 3 is temporarily stored and supplied to the printer 7. The printer 7 prints out a document, graphics, characters, etc. corresponding to the print data supplied from the printer scanner buffer 6. The scanner 8 reads characters or figures on paper, that is, a document, converts the image into image data (digital data), and prints it in the printer scanner buffer 6
Output to.

The keyboard / mouse interface 9 is
It manages the keyboard 10 and the mouse 11 instead of the CPU 1. The keyboard 10 is operated when, for example, a command is input, and the mouse 11 is used for the display 5
Is operated, for example, when a menu bar (not shown) is clicked.

Image data of a document such as a document, a material, or a report captured by the scanner 8 is recorded on the magneto-optical disk 12 in association with, for example, an ID code of the document.

Next, the operation of the apparatus for recording the image data of the document on the magneto-optical disk 12 will be described with reference to the flowcharts of FIGS. First, in the case where the orientation of the document is constant, that is, when all pages constituting the document are vertically or horizontally placed, in step S1 of FIG. 2, is the document entirely composed of vertically placed pages? Alternatively, it is determined whether or not it is configured horizontally. If it is determined in step S1 that the document is entirely composed of vertically arranged pages, the process proceeds to step S2, and the scanner 8 is given a vertical designation indicating that the document is composed of vertically arranged pages. Done,
Go to step S4. If it is determined in step S1 that the document is composed of all horizontal pages, the process proceeds to step S3, and the scanner 8 is given a horizontal designation indicating that the document is composed of horizontal pages. After that, the process proceeds to step S4.

In step S4, the image of the document is captured by the scanner 8, and the image is converted into image data in accordance with the vertical designation in step S2 or the horizontal designation in step S3.

That is, a document having a horizontal length X and a vertical length Y as shown in FIG. 5A is set in the scanner 8 vertically, for example, and the vertical designation is made in step S2 ( If the document is a portrait document), in step S4,
Image data D ₁ , read by scanning the document from the left to the right by the scanner 8 sequentially in the downward direction.
D ₂ , ..., D _n , D _{n + 1} , ..., D _{n (m-1) +1} , ...
., D _mn is output as is.

Further, a document having a horizontal length X and a vertical length Y as shown in FIG. 5A is set in the scanner 8 vertically, for example, and the horizontal designation is made in step S3 ( If the document is a horizontal document), in step S4, the image data D ₁ , D ₂ ,
..., D _n , D _{n + 1} , ..., D _{n (m-1) +1} , ..., D
_mn is obtained by rotating the document shown in FIG. 5A right by 90 degrees by the scanner 8 from left to right of a document having a horizontal length Y and a vertical length X (FIG. 5B). Image data D when scanning is sequentially repeated downward
_{n (m-1) +1} , ..., D _{n + 1} , D ₁ , ..., D ₂ , ...
, D _mn , ..., D _n are rearranged so as to form the same data sequence.

Here, the case where a document (paper) where X <Y and the lengths of two adjacent sides are X or Y is set vertically in the scanner 8 is shown in FIG. 5 (a). The orientation of the document refers to the case where it is set in the scanner 8, and the case where the document (paper) is set sideways in the scanner 8 means the orientation of the document shown in FIG. Scanner 8
When set to.

Note that a document having a horizontal length X and a vertical length Y as shown in FIG. 5A is set in the scanner 8 horizontally instead of vertically, and the vertical designation is performed in step S2. If the document is a vertically placed document, in step S4, the image data read by sequentially repeating the scanning of the document from the left to the right by the scanner 8 in the downward direction is opposite to the case described above. Can be rearranged. Further, a document having a horizontal length X and a vertical length Y as shown in FIG. 5A is set in the scanner 8 not in the vertical direction but in the horizontal direction, and the horizontal designation is performed in step S3 (the document). Is a horizontally placed document), in step S4, the scanning of the document from the left to the right by the scanner 8 is sequentially repeated downward, and the read image data is output as it is.

Then, in step S5, after the header is added to the image data, for example, CCITT recommendation T.264. It is compressed by the compression method based on the encoding method conforming to the standard of No. 6. Then, it is associated with the ID code of the document inputted in advance and recorded on the magneto-optical disk 12, and the processing is terminated.

Here, a document having a horizontal length X and a vertical length Y as shown in FIG. 5A, that is, a vertically placed document is set in the scanner 8 vertically, for example, and is designated vertically in step S2. Is performed (the document is a portrait document), step S
5, the image data D ₁ , D ₂ , ...,
D _n , D _{n + 1} , ..., D _{n (m-1) +1} , ..., D _mn are, for example, the data length thereof, the vertical length Y of the document, and the horizontal length of the document. A header of X is added (FIG. 6 (a)).

A document having a horizontal length Y and a vertical length X as shown in FIG. 5B, that is, a horizontally placed document is set in the scanner 8 vertically, for example, and the horizontal designation is made in step S2. If done (the document is a landscape document), step S
5, the image data D _{n (m-1) +1} , ..., D _{n + 1} , D ₁ , ..., D whose arrangement has been changed in step S4
_2, · · ·, D _mn, · · ·, to D _n, for example, the data length, a vertical length X, and the transverse headers having a length Y of the document is added in the document (Figure 6 (b )).

As described above, whether the document is placed vertically or horizontally is specified, and the image of the document is converted into image data in accordance with the orientation of the document vertically or horizontally, It is recorded on the magnetic disk 12. Therefore,
If you read this out and display it as it is, vertically placed documents will be displayed vertically, and horizontally placed documents will be displayed horizontally, so that users can easily view the documents without feeling bothersome. can do.

Next, the image data of the document in which the vertically placed pages and the horizontally placed pages are mixed is used as the magneto-optical disk 12.
In the case of recording in step S11 shown in FIG.
It is determined whether the page of the document for which the image data is currently fetched is a vertical page or a horizontal page. If it is determined in step S11 that the page is a vertically placed page, the process proceeds to step S12, the portrait is designated for the scanner 8, and the process proceeds to step S14. When it is determined in step S11 that the page is a horizontally placed page, the process proceeds to step S13, the scanner 8 is designated to be landscape, and the process proceeds to step S14.

In step S14, the image of the document is converted into image data by the scanner 8 and the same as in step S4 of FIG. 2 described above corresponding to the vertical designation in step S12 or the horizontal designation in step S13. Then, the data of the image data is rearranged. Then, in step S15, it is determined whether or not the images of all the pages forming the document have been captured. If it is determined in step S15 that the images of all the pages forming the document have not been captured, the process returns to step S11, and until it is determined in step S15 that the images of all the pages configuring the document are captured. The processing of steps S11 to S15 is repeated.

If it is determined in step S15 that the images of all the pages forming the document have been captured, the process proceeds to step S16, and the image data output from the scanner 8 is the same as in step S5 of FIG. Then, the data is recorded on the magneto-optical disk 12, and the process ends.

Further, in addition to the processing of steps S11 to S16 shown in FIG. 3 described above, for example, by the processing of steps S21 to S24 shown in FIG. 4, a document in which vertically placed pages and horizontally placed pages are mixed. Image data may be recorded on the magneto-optical disk 12.

That is, in step S21 of FIG. 4, the images of all the pages of the document are read by the scanner 8, and the process proceeds to step S22, where each page of the document is vertically or horizontally placed. A vertical designation or a horizontal designation indicating that is given to the scanner 8 and the process proceeds to step S23.

In step S23, as in step S4 of FIG. 2, the image data data of each page of the document is rearranged in correspondence with the vertical designation or the horizontal designation in step S22, and step S24 is performed. Proceed to. In step S24, the image data rearranged in step S22 is recorded on the magneto-optical disk 12 in the same manner as in step S5 of FIG. 2, and the process ends.

Here, by the processing of FIG. 3 or 4, not only the image data of the document in which the vertically placed page and the horizontally placed page are mixed, but also the document in which pages of different sizes are mixed (see FIG. 7 ( The image data of a)) can be recorded on the magneto-optical disk 12. For example, when the image data of a document as shown in FIG. 7A is recorded on the magneto-optical disk 12, the data format is as shown in FIG. 7B. In the figure, A, C, or E indicates the vertical length of the document, and B, D, or F indicates the horizontal length of the document.

Next, when an image corresponding to the image data of the document recorded on the magneto-optical disk 12 is displayed on the display 5 by any of the processes shown in FIGS. 2 to 4, first, the ID code of the document is changed. It is input from the keyboard 10. Then, in step S31 shown in FIG. 8, the image data of the document associated with the ID code input from the keyboard 10 is searched, the process proceeds to step S32, and the image data of the document searched in step S31 and the attribute thereof. As the values, for example, the vertical length (A, C, or E in FIG. 7A) and the horizontal length (B, D, or F in FIG. 7A) of the document are calculated from the magneto-optical disk 12. Read (decompressed and read).

Then, in step S33, the image corresponding to the image data of the document read in step S32 is displayed on the display 5 in a size according to the vertical length and the horizontal length as its attribute values. The window is displayed in the opened window 21 (FIG. 9) or 31 (FIG. 10), and the process ends.

Here, as described above, the magneto-optical disk 1
In FIG. 2, since the image data of the document is preliminarily recorded in correspondence with the vertical or horizontal orientation of the document, regardless of the orientation in which the document is set in the scanner 8 at the time of recording, for example, a document of A4 size is used. The page of a horizontal document is
As shown in FIG. 9, the document is displayed in landscape orientation, and the page of a portrait document of A4 size is displayed in portrait orientation as shown in FIG. Furthermore, a document in which both A4 size horizontal pages and vertical pages are mixed is shown in FIG.
As shown in, the display 5 is partially overlapped.

By the way, when the pages of the document are displayed on the display 5 while partially overlapping each other as shown in FIG. 11, the lower page (in FIG. 11, window 2) is displayed.
There is a case that the A4 size horizontal page displayed in 1 is difficult to see and the contents cannot be confirmed. Therefore, together with the image data of the document, for example, data obtained by reducing the image of the document (hereinafter referred to as reduced image data)
It is conceivable to record the data on the magneto-optical disk 12.

By reading the reduced image data recorded on the magneto-optical disk 12 in this way and displaying the corresponding reduced images so as not to overlap each other, the contents can be easily confirmed.

In this case, the reduced images of the documents (pages) placed horizontally or vertically are not displayed in landscape orientation or portrait orientation, but are displayed in portrait orientation, for example. In order to distinguish between a reduced image of a document (page) and a reduced image of a vertically placed document (page), as shown in FIG. 12, a horizontally displayed document (page) displayed vertically is displayed. Window 4 opened on display 5 with the reduced image framed
It can be displayed within 1.

FIG. 13 shows a reduced image of an actual document in which the vertically placed pages and the horizontally placed pages are mixed and displayed in the window 51 opened on the display 5 in this way.

The case where the image recording device and the image display device of the present invention are applied to the electronic filing device has been described above, but the present invention is not limited to the electronic filing device, but also records and displays an image of a predetermined size. It can be applied to any device that does.

In this embodiment, the document image data is rearranged in step S4, S14, or S23 so that the document is rotated by 90 degrees, but the invention is not limited to this, and the document image data may be arbitrarily arranged, such as 180. The document image data can be rearranged so that the document is rotated by the angle of. Further, in the present embodiment, the magneto-optical disk 12 is used as the recording medium for recording the image data of the document, but the recording medium is not limited to the magneto-optical disk, and a recording medium such as a magnetic disk or a magnetic tape may be used. it can.
