Abstract

PURPOSE:To realize smooth paging with less waiting time by reducing the size of image data having an excessively large size in advance at the time of filing the image data. CONSTITUTION:When a filing start command is given to a control circuit 14 from a keyboard 9, the circuit 14 actuates and instructs an image scanner 2 to read an original 1. When the size of the image data in a working memory 3 is larger than the screen of a display 4, a thinning process is performed so as to reduce the size of the image data. Then the circuit 14 checks the presence of an original left in the scanner 2 and, when no original is left, performs a management process to file the read plural pages in one document. When a document registered in a file memory 6 is read out, the image data are stored in the working memory 3 after the data are decoded by means of a decoding circuit 7 and displayed on the screen of the display 4.

Description

[Detailed Description of the Invention] Industrial Field of Application This invention is for storing image data such as documents and drawings read from a manuscript with an image scanner on a medium such as an optical disk, and searching and using the data as needed. The present invention relates to an electronic file device, and particularly to speeding up a page turning operation in which image data of each registered page is displayed one after another on a display.

2. Description of the Related Art As shown in FIG. 4, a conventional general electronic file device includes an image scanner 2 with an automatic paper feeding function that reads the image of a document 1, and a scanner that stores at least one page's worth of image data. A working memory 3 having a large capacity, a display 4 for displaying image data in the working memory 3, an encoding circuit 6 for encoding the image data to compress the amount of data, and a display 4 for displaying the image data in the working memory 3; a large-capacity file memory 6 for filing in this format, a decoding circuit 7 for restoring encoded image data, a printer 8 for printing out image data, and a keyboard for an operator to input control information, etc. 9
and a mouse 1o, and a control circuit 11 that controls the entire device.
It is equipped with

When filing a document, when the image scanner 2 reads the original I page by page, the image data is temporarily stored in the working memory 3 and displayed on the display 4, and is also encoded by the encoding circuit 6 and sent to a file. It is stored in the memory 6. When the operator inputs required document management information using the keyboard 9, the control circuit 1o writes the management information into the file memory 6 and creates a file in a predetermined format.

When outputting a filed document, when the operator specifies the desired document using the keyboard 9, the image data of the corresponding document is read page by page from the file memory 6, and the image data is decoded by the decoding circuit 7 and processed. It is stored in the memory 3 and displayed on the display 4. Furthermore, if a print command is input, the image data in the working memory 3 is printed by the printer 8.

Problems to be Solved by the Invention In the conventional device described above, when the image data to be read out from the file memory 6 and displayed is larger than the display screen size of the display 4 and has a large amount of data, the image data is thinned out by thinning processing. It is displayed after being reduced.

This size reduction processing takes a relatively long time, but in conventional devices, image data reduction processing is performed at the display output stage, so the image data of the corresponding page is displayed on the display 4 after a display command is given. The problem was that it took a long time.

In particular, when turning pages to display each page of a filed document one after another, the dog-sized image data is displayed slowly, making it difficult to turn the pages smoothly.

This invention was made in view of the above-mentioned conventional problems.The purpose of this invention is to enable high-speed page turning operation even when the image data exceeds the display size of the display, just like when using small-sized image data. An object of the present invention is to provide an electronic file device that can perform the following operations.

Means for Solving the Problems Accordingly, in the present invention, in addition to a means for encoding input image data of each page in its original size without reducing it and registering it in a file memory, the input image data is encoded to a predetermined size. If the image data exceeds the size, a means is provided to appropriately reduce the image data, encode it, and register it in the file memory together with the original size image data, so that both the original size and reduced size image data are registered. When reading a page from the file memory, the image data of the reduced size is decoded and displayed on the display.

For large-sized image data that cannot be displayed as is, the necessary reduction processing is performed at the registration stage.
Since the image data of the reduced size is filed together with the original size, there is no need to perform reduction processing at the stage of reading out from the file and displaying it, and display output can be performed at high speed.

Embodiment FIG. 1 shows an electronic file device according to an embodiment of the present invention, which includes a document 1, an image scanner 2, a working memory 3, a display 4, an encoding circuit 5, a file memory 6, a decoding circuit 7, and a printer. 8, keyboard 9, and mouse 10 are the same as those of the conventional device, and the configuration of the characteristic parts of the present invention will be explained below.

Reference numeral 11 denotes a reduction circuit, which reduces the size of the image data of the document 1 read from the image scanner 2 into the working memory 3 by thinning out the data at an appropriate ratio °C. Reference numeral 12 denotes a circuit that selects reduced size image data and transfers it to the decoding circuit 7 when reading out from the file memory 6 a page in which both original size image data and reduced size image data are registered. 13 stores the page in which both the original size and reduced size image data are registered in the file memory 6.
This is a circuit that specifies which image data of the original size or the reduced size should be read out with priority when reading from the image data.

Reference numeral 14 denotes a control circuit that supervises the entire device, and is basically the same as the control circuit 10 of the conventional device (FIG. 4), but by adopting the present invention, the control function is different as follows.

FIG. 2 is a flowchart of an example of the operation when registering a document in the same apparatus, and FIG. 3 is a flowchart of an example of the operation when a registered document is displayed and output.

When a filing start command is given to the control circuit 14 through the keyboard 9, the control circuit 14 starts up the image scanner 2 and instructs it to read one sheet of the original 1 (step 1). The image data of the document 1 is stored in the working memory 3 and displayed on the display 4. At this time, if the size of the image data in the working memory 3 is larger than the display screen of the display 4 (step 2
), the image data is reduced in size by thinning processing to fit the display screen (step 3). If the size of the image data is small, no reduction processing is performed. Next, the image data is encoded and stored in the file memory 6 (step 4), but if the image data is reduced, not only the reduced image data but also the original size image data before reduction is encoded. , and store them in the file memory 6 in association with each other. Next, the control circuit 14 checks whether there is any document left in the scanner 2 (step 5), and if there is, instructs the scanner 2 to read the document (step 1), and if no document remains , performs management processing to file the multiple pages read so far as one document (step 6).

When reading out a document registered in the file memory 6, the document is selected by operating the keyboard 9 or mouse 10 (step 7). If the operator specifies that image data of both the original size and reduced size are registered (step 8), then the reduced data is given priority accordingly. Read file memory 6 with priority,
Naturally, pages without reduced data are read out (steps 9 and 10). The read image data is restored by the decoding circuit 7, stored in the working memory 3, and displayed on the display 4 (step 11).

At this time, if page turning is specified, a series of processes of data reading, decoding, and display are repeated at a predetermined cycle, and page turning is performed (step 12). Furthermore, even if the reduced data is displayed preferentially, if you particularly want to display the original size data or when printing with the printer 8, the original size image data can be stored in the file memory 6.
Read from and output (step 13, step 14)
).

Effects of the Invention As explained in detail above, in the electronic filing device of the present invention, when filing image data, excessively large image data is reduced in advance, so there is no need to perform reduction processing when outputting for display. High-speed response display is possible regardless of data size, and smooth page turning can be achieved with less waiting time. Furthermore, even when data is reduced and registered, the reduced original size data is also registered at the same time, so accurate original size display and high resolution printout can be performed as necessary.
