DETAILED DESCRIPTION

The invention will now be described more fully with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown.

FIG. 1 is a block diagram illustrating a graphical user interface (GUI) display device in a digital image processing apparatus according to an embodiment of the invention. In detail, a digital photographing apparatus that may adjust a GUI is illustrated in FIG. 1. However, the digital image processing apparatus is not limited thereto as in FIG. 1 and may also be an image processing apparatus such as a personal digital assistant (PDA), a personal multimedia player (PMP), etc. This applies also to embodiments to be described later and modified examples thereof.

The overall operation of the digital image processing apparatus is controlled by a CPU 100. The digital image processing apparatus includes a manipulation unit 200 including keys that generate electric signals when manipulated by a user. An electric signal from the manipulation unit 200 is transmitted to the CPU 100 to control the digital image processing apparatus.

In a photographing mode, as the electrical signal from the manipulation unit is transmitted to the CPU 100, the CPU 100 controls a lens driving unit 11, an aperture driving unit 21, and an image pick-up device control unit 31 according to the electrical signal, and accordingly, positioning of lenses 10, an aperture degree of an aperture 20, and sensitivity of an image pick-up device 30 are controlled. The image pick-up device 30 generates data from light incident thereon, and an analog/digital converter 40 converts analog data output from the image pick-up device 30 to digital data. Obviously, the analog/digital converter 40 may not be necessary according to the characteristics of the image pick-up device 30.

Data transmitted from the image pick-up device 30 may be input to the digital signal processor 50 directly or via a memory 60, or to the CPU 100 according to necessity. The memory 60 may be a read only memory (ROM) or a random access memory (RAM). A digital signal processor (DSP) 50 may perform digital signal processing such as gamma correction, white balance modification, and the like. Also, as illustrated in FIGS. 2, 5, and 7, the DSP 50 may include elements such as a data receiving unit 51, a storage unit 52, a resizing unit 53, and a control unit 54. The data receiving unit 51, the storage unit 52, the resizing unit 53, and the control unit 54 may be elements separate from the DSP 50 instead of being elements in the DSP 50, and operations thereof will be described later.

Image data output from the DSP 50 may be transmitted to a display control unit 81 directly or via the memory 60. The display control unit 81 controls a display unit 80 to display an image. According to the current embodiment of the invention, the display unit 80 may be a touch screen. Data output from the DSP 50 may be input to a storage/reading control unit 71 directly or via the memory 60. The storage/reading control unit 71 may store image data in a storage medium 70, according to a signal transmitted from the manipulation unit 200 or automatically. Also, the storage/reading control unit 71 may read data from an image file stored in the storage medium 70 and transmit the data to the display control unit 81 via the memory 60 or another path so as to display an image on the display unit 80. The storage medium 70 may be detachable or be permanently mounted on the digital image processing apparatus.

Hereinafter, operations of the DSP 50 will be described with reference to FIGS. 2 through 7.

According to a first embodiment of the invention, the DPS 50 will be described with reference to FIG. 2. The DSP 50 repositions GUI icons according to display information received from an external display device and then outputs the repositioned GUI icons. To this end, the DSP 50 includes the data receiving unit 51, the storage unit 52, and the control unit 54.

The information receiving unit 51 receives display information from an external display device that is connected to the digital image processing apparatus (e.g., a TV). The display information of the external display device received by the information receiving unit 51 may be information indicating an output resolution of the external display device (e.g., VGA 640×480), information indicating a manufacturer of the external display device (e.g., S corporation or L corporation), information indicating a broadcasting standard of the external display device (e.g., NTSC, PAL), etc. The information receiving unit 51 receives the display information of the external display device via an image transmission path or any of other paths.

The storage unit 52 stores position information of basic GUI icons and reposition information for GUI icons corresponding to at least one piece of the display information of the external display device.

FIG. 3 illustrates basic GUI icons and position information thereof displayed on the display unit 80 of the digital image processing apparatus. The basic GUI icons provided by the digital image processing apparatus may be a battery icon, an image number icon, a card icon, a zoom bar icon, and the like, and the GUI icons are positioned on a boundary of the display unit 80.

FIGS. 4A through 4D illustrate a position data table for the basic GUI icons stored in the storage unit 52 and reposition data tables for the basic GUI icons. Each data table consists of descriptions of the GUI icons, numbers of the GUI icons, and x and y coordinates positions.

In detail, FIG. 4A is a data table in which the position information of the basic GUI icons, that is, positions of the GUI icons, corresponding to the digital image processing apparatus is stored. The position information may correspond to the digital image processing apparatus having a basic output resolution of QVGA (320×240), manufactured by S company, and using NTSC. For example, in the case of the battery icon, its icon number is stored as “ICN_ID_—1”, and its x-coordinate is stored as 5, and its y coordinate is stored as 11.

FIG. 4B is a data table in which is stored reposition information for the GUI icons for when an output resolution of the external display device, for example, VGA(640×480), is different from the output resolution of the digital image processing apparatus, that is, QVGA (320×240). For example, in the case of the battery icon, when changed from an output resolution of QVGA(320×240) to an output resolution of VGA(640×480), its x coordinate is 10 and its y coordinate is 22.

FIG. 4C is a data table in which is stored reposition information for the GUI icons for when a manufacturer of the external display device, for example, L corporation, is different from the manufacturer of the digital image processing apparatus, that is, S corporation. For example, in the case of the battery icon, when changed from S corporation to L corporation, its x coordinate is changed to 15 and its y coordinate is changed to 23.

FIG. 4D is a data table in which is stored reposition information for the GUI icons for when a broadcasting standard of the external display device, for example, PAL, is different from the broadcasting standard of the digital image processing apparatus, that is, NSTC. For example, in the case of the battery icon, when changed from NSTC to PAL, its x coordinate is changed to 6 and its y coordinate is changed to 13.

The control unit 54 searches for the reposition information for the GUI icons corresponding to the display information received by the information receiving unit 51 from the storage unit 52 and repositions and displays the GUI icons on the external display device. The information receiving unit 51 searches for a data table corresponding to the received display information from among the data tables of FIGS. 4A through 4D, and repositions each of the GUI icons according to the reposition information stored in the corresponding data table. If there are two or more data tables corresponding to the received display information existing in the storage unit 52, the control unit 54 assigns priorities to the data tables. For example, if the received display information includes information indicating that the external display device has a VGA output resolution, information indicating that the external display device is manufactured by L corporation, and information indicating that the external display device uses PAL, higher priority may be assigned to the information indicating the manufacturer, and thus the reposition information in the data table of FIG. 4C may be used for repositioning the GUI icons. The priority is not fixed and may be set according to the user.

According to a second embodiment of the invention, the DSP 50 will be described with reference to FIG. 5. When an external display device is connected to the digital image processing apparatus, the user may input a size adjustment signal while viewing the displayed GUI on the external display device, the DSP 50 resizes the GUI and outputs the GUI according to the size adjustment signal. Compared to the embodiment of FIG. 2, while the GUI icons may be repositioned according to display information of an external display device, according to the current embodiment, the GUI may be resized. To this end, the DSP 50 includes the resizing unit 53 and the control unit 54.

The resizing unit 53 resizes a basic GUI to any of various sizes. a GUI generally have a size corresponding to a screen resolution of QVGA (320×240), but may be resized to another size, for example, VGA(640×480).

The control unit 54 controls resizing performed by the resizing unit 53 in response to the size adjustment selection signal input by the user, so that the GUI may be sized to be included within the external display device. The resized GUI may be moved to a center, to a lower right end, or to a right side of a screen of the external display device.

FIGS. 6A through 6D illustrate a resized GUI 601 displayed on a screen of an external display device. In FIG. 6A, the resized GUI 601 is positioned at a lower right end of the screen. In FIG. 6B, the resized GUI 601 is positioned on a right side of the screen. In FIGS. 6C and 6D, the resized GUI 601 is positioned at a center of the screen of the external display device.

The user may reposition and resize the GUI 601 while viewing the GUI 601 displayed on the screen of the external display device. The control unit 54 repositions and resizes the GUI 601 in response to a signal input by the user for repositioning and resizing the GUI 601 and outputs the adjusted GUI screen 601 to the external display device.

According to a third embodiment of the invention, the DSP 50 will be described with reference to FIG. 7. The DSP 50 resizes a basic GUI according to display information received from an external display device and then outputs the GUI. Compared to the previous embodiments, wherein each of GUI icons are repositioned according to the display information of the external display device in the embodiment of FIG. 2, and wherein the GUI is resized in the embodiment of FIG. 5, resizing information of the GUI is stored in a storage unit in the current embodiment. Thus, the GUI is resized according to the display information received from the external display device. To this end, the DSP 50 includes the information receiving unit 51, the storage unit 52, the resizing unit 53, and the control unit 54.

The information receiving unit 51 receives the display information from the external display device connected to the digital image processing apparatus.

The information receiving unit 51 receives the display information of the external display device via an image transmission path or any of other paths.

The storage unit 52 stores basic GUI screen information and GUI resizing information corresponding to at least one piece of the display information.

The resizing unit 53 resizes the basic GUI to another size according to the GUI resizing information stored in the storage unit 52.

The control unit 54 searches for the GUI resizing information corresponding to the display information received by the information receiving unit 51, from the storage unit 52, to resize the GUI and then resizes and outputs the same on the external display device. If there are two or more pieces of resizing information corresponding to the received display information, the control unit 54 assigns priorities thereto. For example, when the received display information are information indicating that the external display device has a VGA output resolution, information indicating that the external display device is manufactured by L corporation, and information indicating that the external display device uses PAL, higher priority may be assigned to the information indicating the manufacturer, and the GUI is resized according to resizing information corresponding to the manufacturer. The priority is not fixed and may be set according to the user.

Also, the control unit 54 repositions the GUI in response to a position adjustment signal input by the user. The resized GUI may be moved to a center, a lower end, or a right side of a screen of the external display device.

Hereinafter, a method of displaying a GUI in a digital image processing apparatus according to embodiments of the invention will be described with reference to FIGS. 8 through 10. The method may be performed inside a digital image processing apparatus as illustrated in FIG. 1. In detail, methods may be performed in the DSP 50 with the help of other elements of the digital image processing apparatus to perform the main method.

First, a method of displaying a GUI according to an embodiment of the invention will be described.

When an external display device is connected to a digital image processing apparatus in operation 801, the DSP 50 receives display information from the external display device (e.g., TV) in operation 803. Examples of the display information received by the DSP 50 are information indicating an output resolution of the external display device (e.g., VGA 640×480), information indicating a manufacturer of the external display device (e.g., S corporation, L corporation), and information indicating broadcasting standards of the external display device (e.g., NTSC, PAL). The DSP 50 receives the display information of the external display device via an image transmission path or another path.

In operation 805, after the DSP 50 receives the display information of the external display device, whether the output resolution of the external display device has changed is determined.

In operation 807, if the output resolution of the GUI has changed, the DSP 50 determines a new size a changed output resolution.

Next, in operation 809, the DSP 50 searches for reposition information for GUI icons, according to the changed output resolution. In the DSP 50, a position data table of the basic GUI icons as illustrated in FIG. 4A, a reposition data table for the GUI icons for when an output resolution of the external display device, for example, VGA(640×480), is different from an output resolution of the digital image processing apparatus, for example, QVGA(320×240), as illustrated in FIG. 4B, a reposition data table for the GUI icons for when a manufacturer of the external display device, for example, L corporation, is different from a manufacturer of the digital image processing apparatus, for example, S corporation, as illustrated in FIG. 4C, and a reposition data table of GUI icons for when a broadcasting standard of the external display device, for example, PAL, is different from a broadcasting standard of the digital image processing apparatus, for example, NTSC, as illustrated in FIG. 4D are stored, and the DSP 50 searches for the stored data tables and checks position information of the GUI icons to be repositioned.

The DSP 50 repositions the GUI icons according to the position information found in operation 811, and outputs the repositioned GUI icons on the external display device in operation 813. If there are two or more data tables corresponding to the received display information, the DSP 50 assigns priorities thereto. For example, when the received display information includes information indicating that the external display device has a VGA output resolution VGA, information indicating that the external display device is manufactured by L corporation, and information indicating that the external display device uses PAL, higher priority may be assigned to the manufacturer and the reposition information in the data table of FIG. 4C may be used for repositioning the GUI icons. The priority is not fixed and may be set according to user.

Next, a method of displaying a GUI according to another embodiment of the invention will be described with reference to FIG. 9.

When an external display device is connected to a digital image processing apparatus in operation 901, the DSP 50 determines whether to resize a GUI in operation 903. That is, the user determines whether to resize the GUI according to a selection signal input by the user viewing the GUI displayed on the external display device.

When the user determines to resize the GUI by inputting the selection signal, the DSP 50 receives the signal in operation 905, and resizes the basic GUI in operation 907.

Next, the DSP 50 outputs the resized GUI to the external display device in operation 909. The resized GUI may be moved to a center, a lower right end, or a right side of a screen of the external display device according to selection by the user. In FIG. 6A, a resized GUI 601 is positioned at a lower right end of the screen. In FIG. 6B, the resized GUI 601 is positioned at a right side of the screen. In FIGS. 6C and 6D, the resized GUI screen 601 is positioned at a center of the screen of the external display device.

The DSP 50 inquires the user whether the user is satisfied with the resized GUI displayed on the external display device, and when the user is satisfied, the method is ended, and if not, the method returns to operation 905 to resize the GUI to another size in operation 911.

Next, a method of displaying a GUI according to another embodiment of the invention will be described with reference to FIG. 10.

When an external display device is connected to a digital image processing apparatus in operation 1001, the DSP 50 receives display information from the external display device (e.g., TV) in operation 1003. Examples of the display information received by the DSP 50 include information indicating an output resolution, information indicating a manufacturer, information indicating broadcasting standards, or the like. The DSP 50 receives the display information of the external display device via an image transmission path or another path.

In operation 1005, after the DSP 50 receives display information of the external display device, whether the output resolution of the external display device has changed is determined.

In operation 1007, when the output resolution of the external display device has changed, the DSP 50 checks the changed output resolution.

Next, in operation 1009, the DSP 50 searches for resizing information for a GUI screen, according to the changed output resolution. Although not illustrated in FIG. 10, basic GUI screen information and GUI resizing information according to at least one piece of display information are stored in the DSP 50.

In operation 1011, the DSP 50 resizes a size of the basic GUI according to GUI resizing information found in operation 1009, and in operation 1013, outputs the resized GUI to the external display device. If at least two pieces of the GUI screen resizing information corresponding to the received display information exist, the DSP 50 sets a priority. For example, when the received display information are information indicating an output resolution VGA, information indicating L corporation, and information indicating PAL, a priority is set on the manufacturer (L corporation), and a GUI screen is resized according to resizing information corresponding to the L corporation. The priority is not fixed and may be set according to the user.

Also, the DSP 50 repositions the GUI screen in response to a position adjustment signal input by the user. The resized GUI screen may be moved to a center, a lower right end, or a right side of a screen of the external display device.

As described above, according to embodiments of the invention, a position of a GUI or a size of a GUI screen is changed according to external display devices connected to a digital image processing apparatus and output, thereby showing an improved state for a GUI according to an external output.

Also, cropping part of a GUI (or cutting off part of the GUI) due to differences in visible areas despite the same output resolution may be prevented. The differences in visible areas may be due to different manufactures manufacturing the display devices with different specifications. This means that an improved visible area may be provided according to a resolution selected by the user.
