## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application claims the benefit under 35 U.S.C. §119 of Korean Patent Application No. 2004-16222 filed on Mar. 10, 2004, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein in its entirety and by reference.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present general inventive concept relates to a method of setting a driver program that drives an image processing device, and more particularly, to a method of setting a user interface of a driver program that allows the driver program not to interfere with an acquisition result of an application program operated by a user when the driver program of the image processing device is displayed over the application program.
2. Description of the Related Art
Generally, a scanner and other types of image processing devices, such as a multifunction device with a scanning unit, scan a document and convert the scanned result into image data in a predetermined file format, such as a JPEG or a TIFF format, which is, in turn, transmitted to a host, such as a computer. In the computer, a driver program for driving the scanner is installed, and an application program for processing the image data generated by the scanner can also be installed. Examples of the application program are the Photoshop software program by Adobe Systems Incorporated, the Paint software program, and the like. Meanwhile, these application programs are not capable of having direct access to the image data read by the scanner, but are capable of accessing the image data in the file format. In this case, in order for the application program to acquire the image data, there is an inconvenience of requiring several sequential steps to acquire the image data. First, the image data of the document is stored in the file format by operating a scanner program. Then, the scanner program is terminated, and the application program is subsequently operated to access the image data saved in the file format.
Currently, the aforementioned application programs access the image data read by the scanner through a tool-kit without an important name (TWAIN) driver in an operating system, so that the application programs can directly access the read image data.
FIG. 1 is a diagram illustrating a conventional scanning system including a host 100 for processing image data scanned by a scanner 200.
Referring to FIG. 1, the host 100 includes a storage medium 110 having an application program 113, a TWAIN driver 112 and a driver program 111, a control block 120 having a central processing unit (CPU) and a random access memory (RAM), an input device 130, and a display unit 140. In FIG. 1, the application program 113, the TWAIN driver 112 and the driver program 111 are abbreviated respectively as APP, TWAIN and DRIVER.
When the application program 113 for processing the image data, e.g., the Photoshop application program, calls the image data, the application program 113 controls the scanner 200 through the driver program 111 to scan a document (not shown).
The driver program 111, the TWAIN driver 112 and the application program 113 included in the storage medium 110 of the host 100 are operated under a typical Windows operating system or a Linux operating system.
The scanner 200 is operated by the driver program 111 and inputs a scanned result, i.e., the image data, to the storage medium 110. At this time, the image data is input to the TWAIN driver 112 through the driver program 111, and the application program 113 can directly acquire the image data through the TWAIN driver 112. That is, it is unnecessary for the application program 113 to access the image data stored in a file format created by an additional scanner program.
FIG. 2 is a diagram illustrating an exemplary result obtained as an application program window 213 and a TWAIN driver window 212 are displayed on a screen.
Referring to FIGS. 1 and 2, as a user starts an application program window 213, if the user wishes to acquire the image data through the application program window 213, a TWAIN driver window 212 that interfaces the driver program 111 with the application program 113 is displayed over the application program window 213. Here, the TWAIN driver 112 allows the application program 113 to directly access the image data created by the scanner 200. When the TWAIN driver window 212 is displayed, the user is able to access the image data while the application program 113 operates. However, as illustrated in FIG. 2, the TWAIN driver window 212 blocks the image data displayed by the application program window 213.
The TWAIN driver window 212 includes a control menu 215 for controlling the image data acquired through the application program 113. In particular, the control menu 215 of the TWAIN driver window 212 includes sub-control menus of an image type control menu 215a, a resolution control menu 215b, an image area control menu 215c and an image size control menu 215d. The control menu 215 adjusts the image data as the user sets the various sub-control menus of the control menu 215. The TWAIN driver window 212 also includes a menu bar 216, a scan button 217, and a preview button 218.
In a case in which the user wishes to scan more than one document, the user has a difficulty in confirming a displayed image of the acquired image data. Also, when the user clicks the TWAIN driver window 212 by using the input device 130, such as a mouse, to move the TWAIN driver window 212 into a different position of the screen, the control block 120 starts operating to handle an interruption made by the input device 130 and as a result, there is a delay in processing the image data by the application program window 113.
In a case in which the scanner 200 scans a number of documents consecutively, it may be impossible or difficult to move the position of the TWAIN driver window 212 through the use of the input device 130. Also, when an image of the image data accessed by the application program window 213 is displayed on the screen, the user may have a difficulty in confirming the acquired image data since the TWAIN driver window 212 blocks the displayed image on the screen.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Reference will now be made in detail to the embodiments of the present general inventive concept, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. The embodiments are described below in order to explain the present general inventive concept by referring to the figures.
FIG. 3 is a diagram illustrating a tool-kit without an important name (TWAIN) driver 310 according to an embodiment of the present general inventive concept.
Referring to FIG. 3, the TWAIN driver 310 appears on a screen on which an application program 300 is displayed when the application program 300 accesses image data obtained through a scanner. The TWAIN driver 310 can include a menu bar 311 including a basic menu to control a color type, a resolution, an area and a size of the image data, a menu to adjust an image quality, a filter menu, and an about menu to provide information regarding the TWAIN driver 310. A number of sub-menus can be included in the basic menu. As illustrated in FIG. 3, a transparent menu 320 to set a transparent setting and a control menu 312 having sub-control menus of an image type control menu 312a, an image resolution control menu 312b, an image area control menu 312c, and an image size control menu 312d. 
The transparent menu 320 sets the TWAIN driver 310 displayed over the application program 300 to be displayed in a transparent state or in a translucent state. The transparent or translucent state can be realized by a predetermined operating system having functions of text and geometric figures displayed on the screen, such as Windows operating system developed by Microsoft Corporation, and the like, and in a host computer having a high capacitance storage medium, such as a processor, a random access memory (RAM) or a hard disk drive (HDD), the operating system and the TWAIN driver 310 can be installed on the hard disk drive. Therefore, the operating system installed into the high capacitance storage medium, such as the hard disk drive, drives the TWAIN driver 310 through the processor, and in turn, sets a transparency level of the TWAIN driver 310. The newly set transparency level is applied to a previously set transparency level of the TWAIN driver 310 installed on the hard disk drive.
Also, the transparent menu 320 can have a set button 321 to set the transparency level of the TWAIN driver 310 when the TWAIN driver 310 is displayed over the application program 300. Once a user clicks the set button 321 by using an input device, a set menu 321a to set the transparency level appears on an inner frame or an outer frame of the TWAIN driver 310. The user then sets the transparency level by moving a set bar 321b through the use of the input device, such as a mouse.
The image resolution control menu 312b of the control menu 312 controls a scanning resolution of the image data scanned by the scanner. For example, the image resolution control menu 312b is capable of setting a target document to be scanned in a resolution of approximately 300 dots per inch (dpi), approximately 600 dpi and approximately 1,200 dpi. The image type control menu 312a is capable of setting an image type when the image data acquired by the scanner 200 is displayed on the screen. As illustrated in FIG. 3, the acquired image data can be set to have a true color of a RGB type. The image area control menu 312c allows the user to select a particular area of the scanned image data, and the image size control menu 312d allows the user to increase or decrease the size of an image displayed on the screen corresponding to the image data. As illustrated in FIG. 3, the image size is set to be approximately 100% indicating the size of the original image, and the image size can be greater than or less than approximately 100% to allow the user to view the image on the screen conveniently. The TWAIN driver 310 can also include a scan button 313 to control the scanner to scan the image data, and a preview button 314 to allow the user to preview the image corresponding to the image data scanned by the scanner.
FIG. 4 is a diagram illustrating the TWAIN driver 310 of FIG. 3 in which the transparent setting is set. After the transparent setting is applied to the TWAIN driver 310, a portion of the TWAIN driver 310 that is displayed over the application program 300 becomes transparent or translucent and thus, the displayed image of the image data transferred from the scanner is not blocked by the TWAIN driver 310. As a result of this transparently or translucently transformed TWAIN driver 310, the user is able to directly confirm a portion of the image overlapping with the TWAIN driver 310. Even though the TWAIN driver 310 is in a transparent or translucent state, the user is able to adjust a quality of the image by controlling the image size, the resolution and the like through using the various sub-control menus 312a to 312d of the control menu 312. Although this embodiment of the present general inventive concept is described using the TWAIN driver, it is possible to apply this transparent function to a windows image acquisition (WIA) driver by Microsoft, an image and scanner interface standard (ISIS) driver, or any other acceptable alternative. Also, in addition to the scanner, such an image processing device as a printer, a digital photocopier, a multifunction apparatus, and the like, can alternatively be used with the transparent function, so that a result acquired by the application program is not blocked when being displayed on the screen.
FIG. 5 is a flowchart illustrating a method of setting a transparent setting of a TWAIN driver according to an embodiment of the present general inventive concept.
Referring to FIGS. 3-5, at operation S410, when a user desires to acquire image data scanned by the scanner 200 through the application program 300, the user determines whether to set the transparent setting. Then, at operation S420, the user loads the TWAIN driver 310 capable of turning on or off the transparent setting on the screen, or the application program 300 automatically loads the TWAIN driver 310.
Next, at operation S430, the user clicks a check box of the transparent menu 320 that allows the user to turn on or off the transparent setting by using the input device, e.g., a mouse, whereby the transparent setting is activated. Thereafter, at operation S440, the user can click the set button 321 to load the set menu 321a on the screen and then, set the transparency level using the loaded set menu 321a. At operation S450, the user can close the set menu 321a with the set transparency level in order to apply the set transparency level to the TWAIN driver 310. Although not illustrated, there may be a case in which the TWAIN driver 310 has an application key to apply the set transparency level of the TWAIN driver, and in this case, the change in the set transparency level of the TWAIN driver is applied by clicking the application key. As illustrated in FIG. 4, when the transparent setting is applied to the TWAIN driver 310, the transparent or translucent TWAIN driver 310 is displayed on the application program 300.
FIG. 6 is a flowchart illustrating a method of displaying the TWAIN driver 310 with the transparent setting according to an embodiment of the present general inventive concept.
Referring to FIGS. 3, 4, and 6, at operation S510, a user operates the application program 300, which acquires the image data from the scanner and processes the acquired image data thereafter. Examples of the application program 300 are Photoshop, Paint Shop Pro, and the like, which can be operated by a driver selected from a group including the TWAIN driver 310, the WIA driver, and the ISIS driver. Currently, the TWAIN 310 driver is the most commonly used driver in image processing devices and drivers corresponding to the image processing devices. Although the embodiments of FIGS. 3-6 of the present general inventive concept describe the TWAIN driver 310 as an exemplary driver, the WIA driver and the ISIS driver can be similarly applied.
Next, at operation S520, the TWAIN driver 310 determines whether the user activates the transparent setting. If the transparent setting is activated, at operation S530, the TWAIN driver 310 verifies the set transparency level with respect to the transparent setting set by the user. Afterwards, the TWAIN driver 310, at operation S540, converts a state of the TWAIN driver 310 displayed on the screen into a transparent or translucent state according to the set transparency level. Conversely, if the TWAIN driver 310 is not set with the transparent setting, at operation S550, the TWAIN driver 310 is displayed directly over the application program in an opaque state.
According to the present general inventive concept, there is provided an effect that an acquired result by an application program operated by a user is not blocked by a driver program, and a scanning operation can be operated at an optimum environment by controlling a transparency level of the driver program displayed over the application program. Although the present general inventive concept describes in detail a transparent setting of a TWAIN driver based on a scanner, image processing devices such as a printer, a photocopier, a multifunction apparatus, and the like can be applied similarly as an alternative to the scanner, and a WIA driver, an ISIS driver, and the like can be applied similarly as an alternative to the TWAIN driver.
Although a few embodiments of the present general inventive concept have been shown and described, it will be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the general inventive concept, the scope of which is defined in the appended claims and their equivalents.
