The present invention relates to a host terminal device for scanning a document using a scanner and a method thereof. More particularly, when a predetermined scan form is selected, the host causes the scanner to scan only an image in an area corresponding to the selected scan form. It relates to a terminal device and a method thereof.

With the dissemination and development of computers, the development of computer peripherals that make computers more versatile is also accelerating. Examples of computer peripherals include printers, scanners, copiers, facsimiles, multifunction peripherals, and the like.

In the case of a scanner, a user may execute a scanner driver program on a host terminal device, input a scan command, and then input a document to be scanned into the scanner. The scanner driver program is a program that allows the host terminal device to recognize the scanner and exchange data with each other. The scanner scans the input document, generates scanned image data, and transmits the scanned image data to the host terminal device. When the scan driver data is received, the scanner driver program stores the received data in the terminal device internal memory or an external server.

On the other hand, when the scanner sends a scan command, it is common to scan the entire document. Therefore, when there are a plurality of documents to be scanned, the same contents are repeatedly scanned if each document contains the same contents. Accordingly, there is a problem that a lot of time is consumed in the scanning process and the storage space is unnecessarily wasted because the size of each scan image data is large.

On the other hand, in order to prevent such a problem, according to a known technique, the user can set the scan area by setting the scan option on the host terminal device. In this case, the scanner scans only the image within the set area and transmits the image to the host terminal device. However, according to this conventional technology, there is a difficulty in that the user must specify the width and height of the area to be scanned directly, and input a scan start point. In addition, the set area is applied to all documents in common. Therefore, when documents with different formats are mixed in the middle, there is a problem that unnecessary areas can be scanned. In order to prevent this, the user has to set the printing option differently for each document having a different format, which increases the inconvenience of the user.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to select a predetermined scan form and automatically designate a scan area so that only a necessary part can be scanned, thereby improving scanning speed and scanning image data. The present invention provides a host terminal device and a method of scanning the same, so that the memory capacity to be stored is not wasted and user convenience can be increased.

According to an embodiment of the present invention for achieving the above object, the host terminal device connected to a predetermined scanner to perform a scan operation, the input unit for receiving a scan command, when the scan command is input, at least one An output unit for displaying a list of the above scan forms, and when a predetermined first scan form is selected on the list, scan area information corresponding to the first scan form and the scan command are transmitted to the scanner, And a control unit to cause the scanner to scan only an image in the scan area on a predetermined document.

Preferably, the host terminal device may further include a memory unit for storing image data for the document. In this case, the controller may synthesize the scanned image data and the first scan form to generate image data for the document, and then store the generated image data in the memory unit.

More preferably, if a page to be applied for each scan form is designated after a plurality of scan forms are selected on the list, the controller may include scan area information corresponding to the scan form designated for each page of a document to be scanned by the scanner; You can send a scan command.

According to an embodiment of the present disclosure, the scan method using the host terminal device connected to a predetermined scanner corresponds to the first scan form when a predetermined first scan form is selected from at least one previously created scan form. Transmitting scan area information and a scan command to the scanner, the scanner scanning an image in the scan area on a predetermined document, and combining the scanned image data and the first scan form, and then storing It includes a step.

Preferably, when a page to be applied for each scan form is designated after a plurality of scan forms are selected on the list, the scanner transmits scan area information and a scan command corresponding to the scan form designated for each page of the document to be scanned. The method may further include scanning, by the scanner, an image in a different area for each page according to the scan area information.

Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the present invention.

1 is a block diagram illustrating a configuration of a host terminal device according to an exemplary embodiment. The host terminal device may be implemented as an electronic device capable of transmitting and receiving data in connection with a scanner such as a general desktop PC, notebook PC, PDA, electronic notebook, and the like. According to FIG. 1, the host terminal device includes an input unit 110, a control unit 120, an interface unit 130, a memory unit 140, and an output unit 150.

The input unit 110 serves to receive a predetermined selection command from the user. That is, the user may input a program execution command, a scan command, or the like using input devices such as various buttons, a keyboard, a mouse, and a joystick provided in the host terminal device. The input unit 110 recognizes the selection command input by the user and notifies the control unit 120.

When the execution command for the scanner driver program is input through the input unit 110, the controller 120 executes the corresponding program. The scanner driver program creates a user interface window in which scan options and the like can be set.

The controller 120 controls the output unit 150 to display the generated user interface window. The output unit 150 displays a user interface window using display elements such as an LCD monitor, a CRT monitor, and an LED.

A list of previously created scan forms is displayed on the user interface window. The scan form refers to a document format in which only a common part of a document to be scanned is created separately. These scan forms can be created, added, changed or deleted by the user. That is, when a document having basic forms, such as a document outline border, a sending department name, a receiving department name, and a document writing precaution, is prepared, the basic form may be prepared in advance and set and stored as a scan form.

Accordingly, when the user selects a predetermined scan form (hereinafter referred to as a first scan form) using the user interface window, the controller 120 detects scan area information corresponding to the first scan form. The scan area information refers to information on the remaining areas of the entire scan area except for the area where the scan form is located. The scan area information may be expressed as a scan start point, a width width, a height width, and the like. The controller 120 transmits the detected scan area information to the scanner (not shown) through the interface unit 130. The scanner scans only the image in the scan area according to the received scan area information.

The interface unit 130 serves to connect the scanner and the host terminal device. The interface unit 130 may be implemented as a parallel interface, a small computer system interface (SCSI), a universal serial bus (USB), or the like. Scanned image data scanned by the scanner is received through the interface unit 130.

The controller 120 synthesizes the scan image data and the first scan form to generate final image data. The generated image data is stored in the memory unit 140. In FIG. 1, the memory unit 140 may be implemented as a hard disk memory, a memory card, or the like. Alternatively, it may be implemented as a separate server connected to the outside of the host terminal device.

2 is a schematic diagram illustrating an example of a configuration of a user interface window displayed on a host terminal device. According to FIG. 2, the user interface window includes a scan form list display area 210, a preview area 220, and a command selection area 230.

At least one previously created scan form a to h is displayed on the scan form list display area 210. In this case, the scan forms can also be sorted by document size. That is, it is possible to list a to d, which are A4 documents, on the upper part of the scan form list display area 210 and to list e to h, which are A5 documents, on the bottom of the scan form list display area 210.

In this case, a selection area 211 for selecting a scan form and a page designation area 212 for designating a page to which the selected scan form is applied are further displayed at the bottom of each scan form. The check mark is displayed on the selection area 211 according to whether the user selects it. Meanwhile, the page designation area 212 at the bottom of the non-selected scan form may display different colors to indicate that the page selection area is not selected. Meanwhile, the user may select a page to which each scan form is to be applied at once through the page designation area 212 while designating a plurality of scan forms. According to FIG. 2, the first and eleventh pages of the entire 20 page document apply scan form e, the second to fourth pages apply scan form d, and the fifth to tenth pages apply scan form a. . The twelfth to twentieth pages apply the scan form f. Such a scan form can be created by the user in advance using a separate application program (word program, etc.), and then added to the list. You can also delete or change the existing scan form.

The command button selectable by the user is displayed on the command selection area 230. The command button may be a preview button 231, a scan button 232, a cancel button 233, or the like. The user can select a command button by operating a mouse, a keyboard, and the like.

When the user selects the preview button 231, the host terminal transmits a preview command to the scanner. Accordingly, the scanner pre-scans the document and then transmits the pre-scanned image data to the host terminal device.

On the preview area 220, pre-scan image data transmitted from the scanner is displayed. The user may determine the scan form to select by checking an image displayed on the preview area 220.

Meanwhile, according to another exemplary embodiment, the controller 120 may display the scan form selected by the user together with the pre-scan image data on the preview area 220 to overlap each other. Accordingly, the user can easily check which area is actually scanned, which scan form is desired, and the like.

When the scan form e is selected through the user interface window as shown in FIG. 2, scan area information corresponding to the scan form e is transmitted to the scanner. The scanner checks the transmitted scan area information, scans only the image in the scan area, and transmits the scanned image data to the host terminal device.

3 is a schematic diagram for explaining a process of synthesizing the scan form and the scan image data by the control unit 120 of the host terminal device. According to FIG. 3, when the scanner transmits the scan image data SD while the scan form e is selected, the controller 120 causes the scan form e and the scan image data SD to overlap. As described above, since the scan area means the remaining areas except the scan form on the entire document, when the scan form e and the scan image data SD overlap, the final image data SD _final is generated. The controller 120 stores the SD _final as one image file in the memory unit 140.

4 is a flowchart illustrating a scan method according to an embodiment of the present invention. According to FIG. 4, when the user selects a predetermined scan form (S410), the host terminal device detects scan area information corresponding to the selected scan form (S420), and transmits the detected scan area information and a scan command to the scanner. (S430).

The scanner scans only the image in the corresponding area (S440) according to the scan area information transmitted from the host terminal device, and transmits the image to the host terminal device. The host terminal device synthesizes the scanned image data transmitted from the scanner and the selected scan form, generates final image data (S450), and stores the generated image data (S460), thereby completing the scan operation.

As described above, according to the present invention, when a plurality of documents are scanned, a portion common to each document is created in advance in a separate scan form, thereby minimizing the size of the area to be scanned. Accordingly, the scan speed can be improved, and the capacity of the memory in which the scanned data is stored can be saved. In addition, when there are a plurality of documents to be scanned, different scan forms can be specified for each document. Accordingly, when scanning a plurality of documents having different areas to be scanned, it is not necessary to designate a scan area one by one, thereby improving user convenience.

In addition, although the preferred embodiment of the present invention has been shown and described above, the present invention is not limited to the specific embodiments described above, but the technical field to which the invention belongs without departing from the spirit of the invention claimed in the claims. Of course, various modifications can be made by those skilled in the art, and these modifications should not be individually understood from the technical spirit or the prospect of the present invention.
