Patent Application
20140132637
The present application relates to the field of image processing, and more particularly to a method and a device for displaying a cropped image as wallpaper on a display screen of a mobile terminal, which may be viewed in different orientations when the mobile terminal is being rotated in reference to a center line.
Mobile terminals that use an Android 4 operating system (such as a Nexus 7 or a Nexus 10 tablet device, or a smart phone) simultaneously crop a wallpaper image in both the vertical orientation and the horizontal orientation based on a cross-shaped cropping frame (also referred to as a cross-frame).
In this example, a user may prefer to display a full portion of the tiger (140′), as the horizontal wallpaper by zooming in or out, and positioning the rectangle 134 to include the entire tiger (140′) in the horizontal cropping operation. However, by doing so, the vertical cropping operation would also be simultaneously performed on the rectangle (132) portion of the cross-frame (130).
As seen, the existing method enables the user to adjust the size of the cross-frame (130) over the image (140′), and quickly perform simultaneous cropping operations vertically and horizontally. However, the existing method also limits user's controllability in achieving desirable results for both the vertical cropping operation and the horizontal cropping operation.
The embodiments of the present disclosure provide a method and a device for wallpaper cropping which improves the operability or controllability of vertical and horizontal wallpaper cropping operations.
The embodiments of the present disclosure adopt a method for wallpaper cropping comprising:
The embodiments of the present disclosure provide a device for wallpaper cropping operations, which includes at least a processor operating in conjunction with a memory and a plurality of units, the plurality of units include:
The benefits of the embodiments of the present invention compared with the existing simultaneous vertical and horizontal cropping operations are that: each of the first wallpaper cropping operation, the second wallpaper cropping operation and the remaining subsequent wallpaper cropping operations is independent of each other, without predefining which portion of the picture should be cropped from one screen orientation to another screen orientation. In addition, the present disclosure enables a user to customize an appearance of the wallpaper in each of the first wallpaper cropping operation, the second wallpaper cropping operation and the remaining subsequent wallpaper cropping operations, wherein the customizing of the appearance of the wallpaper in each of the first wallpaper cropping operation, the second wallpaper cropping operation and the remaining subsequent wallpaper cropping operations including selecting one of: the same picture initially acquired or a different picture acquired in the corresponding subsequent screen orientation information. Accordingly, the present disclosure solves the problem of poor operability or controllability in the simultaneous vertical screen and horizontal screen cropping in the existing cropping method.
The accompanying drawings are included to provide a further understanding of the claims and disclosure, are incorporated in, and constitute a part of this specification. The detailed description and illustrated embodiments described serve to explain the principles defined by the claims.
The various embodiments of the present disclosure are further described in details in combination with attached drawings and embodiments below. It should be understood that the specific embodiments described here are used only to explain the present disclosure, and are not used to limit the present disclosure.
In order to make clearer the technical solution and advantages of the present disclosure, the present disclosure will be further described in detail in combination with the attached drawings and embodiments. It should be understandable that the embodiments are only used to interpret but not to limit the present disclosure. The technical solution of the present disclosure will be described via the following embodiments.
For the purpose of contrasting the present embodiment from the existing method as illustrated in
A user may re-size by zooming in or zooming out the tiger image (240′) displayed on the screen (210). In the present embodiment, the user may choose to first perform a vertical wallpaper cropping operation. A rectangle (232) may be displayed on the screen (210) as a vertical cropping frame. In this example, the user may prefer to display a full portion of the tiger (240′), as the vertical wallpaper by zooming the rectangle (232) in or out, up or down and positioning the rectangle (232) to select the entire tiger (240′) within the vertical cropping frame of the rectangle (232) before performing the vertical wallpaper cropping operation. By selecting the “NEXT” toolbar, the user confirms the vertical wallpaper cropping operation. Alternately, the user may select the “CANCEL” toolbar to cancel the selection and restart the vertical wallpaper cropping operation.
The user, likewise, may re-size by zooming in or zooming out the tiger image (240′) displayed on the screen (210). A rectangle (234) may be displayed on the screen (210) as a horizontal cropping frame. In this example, the user may prefer to display a full portion of the tiger (240′), as the horizontal wallpaper by zooming the rectangle (234) in or out, up or down and positioning the rectangle (234) to select the entire tiger (240′) within the horizontal cropping frame of the rectangle (234) before performing the horizontal wallpaper cropping operation. By selecting the “NEXT” toolbar, the user confirms the horizontal wallpaper cropping operation. Alternately, the user may select the “CANCEL” toolbar to cancel the selection and restart the horizontal wallpaper cropping operation.
In addition, additional subsequent wallpaper cropping operations in other arbitrary angles may be independently performed in similar manners, as illustrated in
Furthermore, each of the vertical and the horizontal wallpaper cropping operations may be independently carried out respectively, where the corresponding results may be independently stored into a local memory upon completing each of the vertical wallpaper cropping operation, the horizontal wallpaper cropping operation and the remaining subsequent wallpaper cropping operations.
The present embodiment also includes receiving commands from the user to perform zooming and/or moving of the picture, such that the user may be enabled to preview an end result of the picture as the wallpaper in the corresponding vertical screen orientation or the horizontal screen orientation after the wallpaper cropping operations.
The wallpaper cropping operations on the picture (240) may further include performing of wallpaper cropping operation on the picture according to the pending screen orientation information or the subsequent screen orientation information, which may include: recording a start time of the vertical wallpaper cropping operation; and starting of the horizontal cropping operation. The starting of the horizontal cropping operation may include: judging if the start time of the vertical wallpaper cropping operation is same as a start time of a previous wallpaper cropping operation; if yes, continue the vertical wallpaper cropping operation; and if not, proceed to the horizontal cropping operation. In addition, the received command to start the wallpaper cropping operation is triggered by the user, or the triggering is generated by the mobile terminal (200) based on a preset time interval.
For the purpose of contrasting the new embodiment from the previous embodiment as illustrated in
The user may re-size by zooming in or zooming out the tiger image (240′) displayed on the screen (210). In the second embodiment, the user may prefer to display only a face portion of the tiger (240) as the vertical wallpaper (240c) by zooming the rectangle (232) to select the tiger face only, as shown in
The user may re-size by zooming in or zooming out the new tiger picture (241) displayed on the screen (210). In the second embodiment, the user may prefer to display an entire portion of the tiger picture (241) as the horizontal wallpaper (240d) by zooming the rectangle (234) to select the entire tiger picture (241), as shown in
As shown in
Each of the vertical and the horizontal wallpaper cropping operations may be independently carried out respectively, where the corresponding results may be independently stored into a local memory upon completing each of the vertical wallpaper cropping operation, the horizontal wallpaper cropping operation and the remaining subsequent wallpaper cropping operations.
In Step S301, the mobile terminal (200) may receive information of starting a wallpaper cropping operation.
In Step S302, the mobile terminal (200) may acquire a picture (240) to be cropped and the current screen orientation information (i.e., vertical orientation or horizontal orientation) of the mobile terminal (200). In this embodiment, the picture (240) to be cropped may be acquired from a local memory of the mobile terminal or from a network. The current screen orientation information of the mobile terminal may include vertical screen orientation information, horizontal screen orientation information, and inclined screen orientation information (for example, the mobile terminal forms a 45-degree angle relative to the vertical or horizontal line).
In Step S303, the mobile terminal (200) may crop the picture (240) according to the mobile terminal's current screen information.
In Step S304, the user may enter another screen orientation information, and the mobile terminal (2000 may perform a second wallpaper cropping operation on the picture (240), until completion of mobile terminal's remaining subsequent wallpaper cropping operations are completed.
The respective results may be stored after each of the wallpaper cropping operations, and the user may click the NEXT toolbar button to enter into a new wallpaper cropping operation in another screen orientation. The user may alternately, cancel and restart the operation by clicking the CANCEL toolbar button, or even return to the main menu to restart the wallpaper cropping operation.
By separating individual wallpaper cropping operations, the disclosure solves the problems of inflexibility or poor controllability due to the simultaneous vertical and horizontal cropping operations in the existing wallpaper cropping method. Moreover, when the cropping of a picture is completed, the effect of the completed picture when used as wallpaper may be previewed by zooming and/or moving the cropped picture, and the previewed effect is the same as that of the picture when it is finally returned and set as the desktop wallpaper, avoiding the problem of local zoom-in display of the wallpaper in the state of the art, which can reduce the user's visual experience (it should be specified that, in the state of the art, the wallpaper is automatically zoomed by the system instead of adjusted by the user). Besides, the screen size is taken as the size of the picture cropping frame, thus solving the problem whereby a part of the picture area cannot be cropped as the existing cropping frame can only be zoomed within the screen scope.
The wallpaper cropping device (400) may include at least a processor (450) operating in conjunction with a local memory (460) to carry out wallpaper cropping operations. The disclosure may be implemented in both hardware and in software within the wallpaper cropping device (400). If implemented as software, the software may be stored in a non-transitory computer-readable medium having stored thereon, a computer program having at least one code section being executable by a processor in a machine for causing the machine to perform the functions or steps as described in
