## Background
BACKGROUND
1. Technical Field
Embodiments of the present disclosure are related to electronic device management systems and methods, and particularly to a device providing display background rotation and a method thereof.
2. Description of Related Art
Since mobile electronic devices are often used as personal organizers, they frequently offer personalization capability, such as providing a display background program. For practical purposes, the display background program may provide a function that changes the display background of a mobile electronic device periodically. For example, if the mobile electronic device includes two images A and B, the display background program may rotate image A as a display background in the daytime, and image B as the display background at night. However, to rotate the display background according to other parameters of the mobile electronic device, the change must be made manually, such as, for example, to display an image captured in New York when the user is in New York.
Therefore, there is a need for a device and method to overcome the described limitations.

FIG. 1 is a block diagram of one embodiment of a mobile electronic device 1 comprising a display background rotation system 3. The display background rotation system 3 may be used to vary the display background on a display device 2 of the mobile electronic device 1 according to a location of the mobile electronic device 1. In one embodiment, the mobile electronic device 1 includes a display device 2, a camera device 5, a navigation device 6, a near field communication (NFC) device 7, and a memory system 8. The camera device 5 may be used to capture one or more images, such as an image of the Statue of Liberty in New York. The NFC device 7 enables the exchange of data between the mobile electronic device 1 and any other electronic device (e.g., a digital camera, a mobile phone, or a personal computer). The navigation device 6 receives global positioning system (GPS) signals from one or more satellites, and determines the location of the mobile electronic device 1 accordingly. In one embodiment, the navigation device 6 may be, but is not limited to, an assisted GPS (A-GPS) device, or a GPS ONE device.
The memory system 8 stores one or more images. Each of the one or more images may be associated with a corresponding location of the mobile electronic device 1. In one embodiment, the memory system 12 may be an internal memory system card or an external memory system card, such as a smart media card (SMC), a secure digital card (SDC), a compact flash card (CFC), a multi media card (MMC), a memory system stick (MS), an extreme digital card (XDC), or a trans flash card (TFC). Depending on the embodiment, the mobile electronic device 1 may be a mobile phone, a personal digital assistant (PDA), a handheld game player, a digital camera, or any other portable electronic device.
In one embodiment, the display background rotation system 3 includes an acquisition module 30, an association module 31, a storage module 32, a determination module 33, a search module 34, and a replacement module 35. One or more computerized codes of the modules 30-35 are stored in the memory system 8. One or more general purpose or specialized processors, such as a processor 4 executes the one or more computerized codes of the modules 30-35 to provide one or more operations of the mobile electronic device 1.
The acquisition module 30 obtains the location of the mobile electronic device 1 from the navigation device 6, and obtains an image from the camera device 5 or the NFC device 7. In one embodiment, the location comprises longitude and latitude information of the mobile electronic device 1. The image may be captured by the camera device 5 or received from other electronic devices (e.g., a digital camera, a mobile phone, or a personal computer) using the NFC device 7.
The association module 31 associates the location of the mobile electronic device 1 with the image. In one embodiment, for example, if the name of the image is “001,” and the location of the mobile electronic device 1 is (114°6′E, 22°12′N), then the association module 31 associates the name of the image “001” with the location (114°6′E, 22°12′N).
The storage module 32 stores the image having the associated location into the memory system 8.
The determination module 33 determines if a current location of the mobile electronic device 1 matches the location associated with a current display background displayed on the display device 2.
The search module 34 seeks an image associated with the current location in the memory system 8, in response to a determination that the current location of the mobile electronic device 1 does not match the location associated with the current display background.
The determination module 33 further determines if an image associated with the current location exists in the memory system 8.
The replacement module 35 replaces the current display background with the image associated with the current location, in response to a determination that an image associated with the current location exists in the memory system 8.
FIG. 2 is a flowchart of acquisition of an image associated with a location of the mobile electronic device in FIG. 1. Depending on the embodiment, additional blocks may be added, while others deleted, and the blocks may also be executed in a different order than described.
In block S200, the acquisition module 30 obtains location of the mobile electronic device 1 from the navigation device 6. As mentioned, the location comprises longitude and latitude information of the mobile electronic device 1.
In block S202, the acquisition module 30 further obtains an image from the camera device 5 or a NFC device 7. As mentioned, the image is captured by the camera device 5 or received from other electronic devices (e.g., a digital camera, a mobile phone, a personal computer) using the NFC device 7.
In block S204, the association module 31 associates the location of the mobile electronic device 1 to the image. For example, if the image is captured at (114°6′E, 22°12′N), then the association module 31 associates the longitude and the latitude information (114°6′E, 22°12′N) with the image.
In block S206, the storage module 32 stores the image having the associated location into the memory system 8.
FIG. 3 is a flowchart of one embodiment of a method for rotating the display background on a mobile electronic device, such as, for example, that of FIG. 1.
In block S300, the acquisition module 30 obtains a current location of the mobile electronic device 1 from the navigation device 6, such as (114°6′E, 22°12′N).
In block S302, the determination module 33 determines if the current location of the mobile electronic device 1 matches a location associated with a current display background displayed on the display device 2. If not, block S304 is implemented. If the current display background matches the current location, the procedure ends.
In block S304, if, for example, the current location of the mobile electronic device 1 is, as mentioned, (114°6′E, 22°12′N) a Hong Kong location, and the current display background is the Statue of Liberty in New York, the search module 34 seeks an image associated with the current location in the memory system 8. In one embodiment, the search module 34 seeks the current location in the memory system 8. According to the example, the search module 34 attempts to locate an image of Hong Kong in the memory system 8.
In block S306, the determination module 33 further determines if an image associated with the current location exists in the memory system 8. As mentioned, if the image associated with the current location exists in the memory system 8, block S308 is implemented. Otherwise, the procedure ends.
In block S308, the replacement module 35 replaces the current display background with the image associated with the current location.
