Abstract

PROBLEM TO BE SOLVED: To improve a data transfer speed from a scanner to a terminal in the scanner data processing system, where data read by the scanner are received by the terminal via a network. SOLUTION: A reception means 221 receives data from a scanner that are transferred via a network 40 and stores the data to a storage device 23. A changeover means 222 selects whether the data are read on a single page or read on a plurality of pages depending on the user selection. A page designation means 225 designates a read page to a single page read means 223, depending on the user designation on a display menu in the case that the data from the scanner are read on plural pages. The single page read means 223 reads only the designated page and gives the result to an expansion means 226. On the other hand, a plural page read means 224 reads all the data from the scanner and gives them to the expansion means 226. The expansion means 226 expands the compressed data. A transfer means 221 sends the expanded data to an application software 21.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scanner data processing method for capturing data read by a scanner on a terminal device side, and a recording medium storing a scanner data processing program. And a recording medium on which a scanner data processing program is recorded.

[0002]

2. Description of the Related Art Normally, data read by a scanner is
The data is transferred to a terminal device such as a personal computer.
The transfer speed at this time is synchronized with the reading speed of the application software. However, in this method, the scanner is occupied until all the data is transferred to the terminal device. Therefore, the scanner cannot be shared by many terminal devices connected via a network.

In order to solve this problem, a method of temporarily storing data read by a scanner has been adopted. FIG. 9 is a block diagram showing a basic configuration of a conventional scanner data processing system using data storage. First, in the scanner 50, the image reading unit 51 reads image data of a document. The read data is compressed by the compression means 52, and the storage means 53 temporarily stores the data. Transfer means 5
4 transfers the stored data to the terminal device 60 side.

In the terminal device 60, the received data is received by the receiving means 61, and the decompressing means 62 decompresses the data and returns it to the original state. Then, this is transferred by the transfer means 63 to the application software 64.

With such a configuration, it is not necessary to synchronize the reading speed of the scanner 50 with the reading speed of the application software 64.

[0006]

However, even in such a configuration, the terminal device 60 is transmitted from the transfer means 54 of the scanner 50.
When the data is transferred, the transfer speed has to be adjusted to the slow reading speed of the application software 64 and the decompression speed of the decompression means 62, and it takes a long time to transfer the data. For this reason, when many terminal devices share the scanner 50 via a network, there is a problem in that scanner data reading processing competes and performance is reduced.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to provide a scanner data processing system capable of improving the data transfer speed from a scanner to a terminal device.

[0008]

According to the present invention, in order to solve the above-mentioned problems, in a scanner data processing system for taking in data read by a scanner on a terminal device side via a network, the data is read by the scanner and compressed. Receiving means for receiving the received data via the network, storage means for storing the received data, decompression means for decompressing the stored data, and transferring the decompressed data to the application software side A scanner data processing method, comprising:

In such a scanner data processing system,
The receiving unit receives the data read and compressed by the scanner via the network. The received data is stored in the storage means, and the stored data is expanded by the expansion means. Then, the transfer means transfers the decompressed data to the application software.

By receiving and accumulating data from the scanner in this manner, it is not necessary to match the data transfer speed on the network with the reading speed of application software or the decompression speed of the decompression means.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. FIG. 2 is a diagram showing a network configuration of the scanner data processing system of the present embodiment. Network 4
0 is connected to the scanner 10 and a plurality of terminal devices such as the terminal devices 20 and 30. The scanner 10 includes an image reading unit 11 that reads image data of a document, and an image processing unit 12 that compresses and transfers the read image. In addition, the scanner 10 temporarily stores the compressed image.
Is provided.

On the other hand, the terminal device 20 is provided with application software 21 for performing image processing, and a scanner driver 22 for reading data from the scanner 10 via the network 40 according to an instruction of the application software 21. . Also, the terminal device 2
0 is provided with a storage device 23 such as a hard disk for storing data from the scanner 10.

The structure of the terminal device 30 is the same as that of the terminal device 2.
Since it is almost the same as 0, the description is omitted here. FIG. 3 is a block diagram illustrating a configuration of a function related to data transfer of the scanner 10. The compression means 121 of the image processing unit 12
The data of the original read by the image reading unit 11 is MR
(Modified READ), MMR (Modified Modified REA)
D), compression by a compression method such as MH (Modified Huffman). The storage device 13 stores the compressed data. The transfer unit 122 reads the data in the storage device 13 and transfers all the data to the terminal device 20 or the like via the network 40 at one time.

FIG. 1 is a block diagram showing the configuration of functions related to scanner data reading processing of the terminal device 20.
The receiving unit 221 receives the data transferred from the scanner 10 via the network 40 and stores the data in the storage device 23. The switching unit 222 switches between reading data in a single page and reading data in a plurality of pages according to a user selection on a display screen described later. By this switching, the data is read by the single page reading means 223.
Alternatively, it is sent to any of the multiple page reading means 224.

When the data from the scanner 10 is a plurality of pages, the page designation means 225 designates a read page to the single page reading means 223 in accordance with a user designation on a display screen described later. The single page reading means 223 reads only the designated page and sends it to the decompression means 226. On the other hand, multiple page read 22
4 reads out all the data from the scanner 10 and sends it to the decompression means 226.

The expansion means 226 expands the compressed data. The transfer means 227 transfers the decompressed data to the application software 21. Next, an operation on the user side for switching between single-page reading and multiple-page reading in the terminal device 20 having such a configuration will be described.

When reading the scanner data, the user first displays a mode switching screen on the display screen of the terminal device 20. FIG. 4 is a diagram showing an example of the mode switching screen. When reading the scanner data, a mode switching screen 241 is displayed on the display screen 24 of the terminal device 20. On the mode switching screen 241, by clicking either the button 241a or the button 241b, the reading mode can be selectively set to either a single page or a plurality of pages.

When, for example, a multi-page mode is selected on the mode switching screen 241, a list of stored documents for the multi-page mode is displayed on the display screen 24. FIG. 5 is a diagram showing a display example of a stored document list for the multiple page mode. In the stored document list 242, the data number, data type, date and time when the data was transferred, the number of pages, the compression method, and the like are displayed for each scan data. The user transfers the data to be transferred to the application software 21,
Select with cursor etc. Thereby, all the selected data is transferred to the application software 21.

On the other hand, when a single page mode is selected on the mode switching screen 241 of FIG.
A list of stored documents for the single page mode is displayed. FIG. 6 is a diagram illustrating a display example of a stored document list for the single page mode. Here, it is assumed that the same data as the scan data displayed in the stored document list 242 in FIG. 5 is displayed. In the stored document list 243, in the case of data including a plurality of pages such as data of number 3 and number 4, the data is displayed for each page number. The user selects a page to be transferred to the application software 21 with a cursor or the like. As a result, the selected page is transferred to the application software 21.

FIG. 7 is a flowchart showing a processing procedure on the side of the scanner driver 22 for executing data transfer to the application software 21 in the multiple page mode. This flowchart starts when data to be transferred is selected in the stored document list 242 in FIG. [S1] 1 is substituted for the variable N of the page. [S2] The Nth page data is acquired from the storage device 23. [S3] The data of the acquired page is decompressed. [S4] The decompressed data is transferred to the application software 21. [S5] N + 1 is substituted for N. [S6] It is determined whether or not the page is the last page. If the page is the last page, this flowchart is ended. If not, the process returns to step S2.

FIG. 8 is a flowchart showing a processing procedure on the scanner driver 22 side for executing data transfer to the application software 21 in the single page mode. This flowchart starts when data to be transferred is selected in the stored document list 243 in FIG. [S11] The page specified by the user is acquired from the storage device 23. [S12] The data of the acquired page is decompressed. [S13] The decompressed data is transferred to the application software 21.

As described above, in this embodiment, the data from the scanner 10 is received by the terminal device 20 and stored, so that the data transfer speed on the network 40 is determined by the reading speed and the decompression speed of the application software 21. There is no need to match. Therefore, the transfer speed of the scanner data can be increased, and the occupation time of the network 40 can be shortened. Therefore, competition by a plurality of terminal devices can be reduced. Further, since the data once read in the terminal device 20 is stored, it can be transferred to the application software 21 at an arbitrary timing.

Further, in this embodiment, since two functions of the single page mode and the plural page mode are provided and both can be switched and selected, the workability is improved. Furthermore, when data consisting of a plurality of pages is read in the single page mode, each page can be selected by the user. Therefore, unlike the conventional scanner driver only in the single page mode, even if the page data other than the first page is the desired page, Can be easily selected and transferred to the application software.

[0024]

As described above, according to the present invention, the data from the scanner is received and stored.
There is no need to match the software reading speed or the expansion speed of the expansion means. Therefore, it is possible to increase the transfer speed of the scanner data, and to reduce competition between a plurality of terminal devices.
