Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
Reference in the specification to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the specification. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
The screen turning display method can be applied to computer equipment with a display screen, such as a mobile phone, a tablet computer, portable wearable equipment and the like. The display screen may refer to a display screen having a pixel Matrix that independently emits Light, such as an AMOLED (Active Matrix Organic Light Emitting Diode) or a PMOLED (Passive Matrix Organic Light Emitting Diode).
In one embodiment, as shown in fig. 1, a method for displaying information on a screen is provided, which is described by taking the method as an example of being applied to a computer device with a display screen, and comprises the following steps:
step S101, a computer device acquires a contour line generated aiming at a selected object on an image;
the image can be a local image stored on the computer equipment or a cloud image stored in a cloud server; the image can be provided with a plurality of objects, such as persons, animals, plants, tables, chairs and the like, and each object presents a specific outline on the image; the selected object may be understood to be an image of interest to the user in the image, for example, in an image showing the person dottien, which occupies a large area of the image (e.g., a self-portrait photograph) or which is in the image focus position (e.g., a guest's picture while playing), the dottien may be considered to belong to a main portion of the image, possibly an object of interest to the user. After the computer equipment obtains the image, the computer equipment can identify the image, determine that the image main body is Dottie, take Dottie as a selected object and extract the outline of Dottie on the image. The computer device can also perform the operations of subject recognition and contour line extraction of the image by using a third-party device.
Step S102, when the display screen is in the screen saver state, the computer device displays the contour line on the display screen as screen saver display content, for example, as shown in fig. 2, the display screen presents a dottiey contour line in the screen saver state.
The display screen can present the contour lines in a static display mode in the process of presenting the contour lines, for example, the contour lines are all displayed on the display screen at the same time.
The display screen may also present the contour lines in a dynamic display manner, such as gradually presenting the contour lines along a preset display direction, for example, the contour line of fig. 3 gradually presents the head to foot of dotti along the top to bottom direction of the display screen, and the contour line of fig. 4 gradually presents the right shoulder to left foot of dotti along the two opposite corner directions of the display screen.
In one possible scenario, if the computer device itself has predefined information screen display content (hereinafter referred to as system display content) belonging to the device system, such as the times ("Friday" and "January 3") shown in fig. 5 a. At this time, the display screen in the breath screen state can simultaneously display the outline and time of dottien.
Further, in order to avoid incomplete information display due to overlapping display of the contour line of the selected object and the system display content, the computer device may detect in advance display positions of the system display content and the contour line on the display screen before the display screen displays the contour line and the system display content, and if the display positions overlap, may adjust a display position of at least one of the system display content and the contour line so that the display position of the system display content on the display screen after the position adjustment does not overlap with the display position of the contour line on the display screen.
Illustratively, as shown in fig. 5a, if the computer detects that the display position of the time is at the upper left of the display screen, and the display position of the dottiey outline is at the lower right of the display screen, and the display position of the dottiey outline are not overlapped, the display screen can directly display the time and the dottiey outline; as shown in fig. 5b, if the computer detects that the display position of the time is below the middle of the display screen, and the display position of the dotti's outline is below the right of the display screen, and the display position of the dotti's outline is overlapped with the display position of the dotti's outline, the display screen may change the display position of the dotti's outline from below the right to above the right, and perform the display.
In addition, the computer device can also adjust the display scale of at least one of the system display content and the contour line, so that the display position of the system display content on the display screen is not overlapped with the display position of the contour line on the display screen after the scale adjustment. It is understood that if the system display content and the contour line are adjusted, the computer device may enlarge the display scale of one of the display content and the contour line and reduce the display scale of the other display content, or reduce the display scales of the system display content and the contour line at the same time.
The adjustment mode is taken as an example to reduce the display proportion of the outline of Dottie: as shown in fig. 5c, if the display position of the time detected by the computer is located at the upper right of the display screen, and the display position of the dotti's outline is located at the lower right of the display screen, and the display position overlap, the computer device may reduce the display scale of the dotti's outline, and display the scaled dotti's outline and the time on the display screen.
In the method for displaying on the screen, when the display screen is in the screen-displaying state, the contour line of the object selected on the image can be presented on the display screen as the screen-displaying content, that is, by displaying the contour line of the object selected on the image in the screen-displaying state, the power consumption can be reduced under the condition of ensuring the personalized display.
In one embodiment, after the display screen is in the screen-off state and the contour line is displayed, the computer device may change the display state of the contour line on the display screen when the time for which the contour line is continuously displayed at the same position of the display screen satisfies a preset time.
That is to say, in the above method, if the time that the contour line is continuously displayed at the same position of the display screen reaches the preset time, the display state of the contour line can be changed to avoid the problem of screen branding caused by long-time continuous display at the same position, which is beneficial to ensuring the normal display effect of the display screen.
Further, the display state of the computer device on the display screen of the modified contour line may be the display position of the modified contour line on the display screen of the computer device. For example, as shown in fig. 6, after the display screen continuously displays the dotti outline at the lower right, if the continuous display time reaches a preset time (e.g., 3 minutes), the computer device may change the dotti outline from the lower right to the upper right, and the display screen displays the dotti outline at the upper right.
Therefore, the computer equipment can avoid the problem of screen branding caused by long-time continuous display at the same position by changing the display position of the contour line, and the normal display effect of the display screen can be favorably ensured.
Further, as shown in fig. 7, when the display position of the outline is changed on the display screen, the computer device may change the display position of the outline from the current display position to the target display position, where the change width of the display position of the outline corresponds to the line attribute of the outline.
The line attribute of the contour line may include a line width, a line density, and the like of the contour line. The outline line is elongated in a direction (this direction may be referred to as an elongation direction), and the line width may be represented by the number of pixels that the outline line occupies on the display screen in a direction orthogonal to the elongation direction; illustratively, the line width is 5 pixels occupied, and then the display position variation amplitude between the current display position and the target display position of the outline line may be 5 pixels.
Since the contour lines of some objects may be represented by densely arranged lines, such as the hairs of a person, the line density may be understood as the density of each line of the contour lines; illustratively, a plurality of lines having a high density of contour lines representing the hair, at which time the display position variation range between the current display position and the target display position of the contour lines may be 10 pixels; illustratively, as another example, one or two of the contour lines of the arm having a low density are presented, and at this time, the display position variation range between the current display position and the target display position of the contour line may be 5 pixels.
Therefore, the display position variation amplitude of the contour line between the current display position and the target display position is determined according to the line attribute of the contour line, and the problem of screen branding can be avoided while the contour line presentation effect is ensured.
The target display position comprises an original display position or a candidate display position of the contour line on the display screen; the distance between the candidate display position and the original display position corresponds to a line attribute of the contour line.
Illustratively, the line attribute is taken as a line width and the line width is taken as 5 pixels. As shown in fig. 9, the contour line of the object is displayed at the original display position of the display screen, and the distance between the original display position and the candidate display position is within 5 pixels, that is, the candidate display position is located in an area centered on the original display position and having a radius of 5 pixels.
Furthermore, the computer equipment can change the display position of the contour line on the display screen, and the contour line can be changed to be displayed as the reconstructed contour line; the reconstructed contour line is constructed at a preset scale based on the contour of the selected object characterized by the contour line.
Illustratively, as shown in fig. 8a and 8b, the computer device may zoom in or out on the outline based on the outline of dottien at a preset scale, and the display screen presents the zoomed in or out outline.
It is understood that when reconstructing the contour line from the selected object, the computer device may enlarge a portion of the contour line and reduce another portion of the contour line; illustratively, the computer device may zoom in on the outline of the dottiee head and zoom out on the outline of the dottiee body part.
It is to be understood that the computer device may only zoom in/out on portions of the contour lines when reconstructing the contour lines from the selected object; illustratively, the computer device may only zoom in/out on the outline of the body part of dotti, maintaining the outline of the original dotti head.
Therefore, the computer equipment changes the display position in a mode of reconstructing the contour line according to the contour of the selected object, so that the contour line can still outline the contour of the selected object, and the problem of screen branding is avoided.
The preset scaling may correspond to a line attribute of the contour line. Illustratively, the line attribute is taken as an example of the line width: under the condition of large line width, if the scaling ratio is too large, contour lines of all parts are overlapped; therefore, under the condition that the line width is larger, the preset scaling ratio may be smaller, for example, the line width is 10 pixels, and the preset scaling ratio is 10%; the line width is 5 pixels and the preset scaling is 20%.
Further, the display state of the computer device on the display screen of the modified contour line may be that the computer device modifies the display color of the contour line on the display screen. Illustratively, the display screen continuously displays the dottiey outline in white, and if the continuous display time reaches a preset time (e.g., 3 minutes), the computer device may change the dottiey outline from white to red, and the display screen displays the dottiey outline in red.
Therefore, the computer equipment can also avoid the problem of screen branding caused by long-time continuous display at the same position by changing the display color of the contour lines, and the normal display effect of the display screen can be favorably ensured.
It is understood that in the information screen display method provided by the present application, the image may be any image, and may include, for example, an image selected by a user from an album, an image as a lock screen wallpaper, an image as a system desktop wallpaper, and the like.
In an embodiment, after obtaining a contour line generated by a selected object on an image, if a preview trigger operation of a user is detected, the computer device may display the contour line on a display screen as preview content displayed on a message screen, so as to implement one-key preview and save time.
In one embodiment, the contour line generated for the selected object on the image is acquired in a case where it is in an idle state and the power supply amount satisfies a preset power supply value condition. For example, at night and when the computer device is in a charging state, the computer device can generate the contour line, so that the situation that the calculation resources of the computer device for processing other instructions are occupied and the generation of the contour line fails under the condition of insufficient power supply is avoided.
In one embodiment, the contour line includes one of a plurality of candidate contour lines; each candidate contour line is from a different image.
Further, the different images may be obtained by filtering from an image set stored locally in the computer device or an image set stored in the cloud server according to an image filtering mechanism.
In the embodiment, the problem of low information screen display efficiency caused by overlong operation time can be solved by screening the images of the image set and then generating the line profile.
In an embodiment, the above screen locking display method may also be used in a screen locking scene of a computer device, and is described by taking a screen locking scene of a mobile terminal as an example: under the condition that the screen locking mode of the mobile terminal is opened, the image of the screen displaying method is used for displaying the display screen in the screen lightening state of the screen locking mode, namely, the outline of the wallpaper of the screen locking is displayed when the display screen is in the screen locking state.
Referring to fig. 10, another method for displaying a message screen provided in the present application is described, which includes the following steps:
in step S1001, the mobile terminal acquires a contour line generated for a selected object on an image.
And step S1002, when the display screen is in the screen-off state, the mobile terminal displays the contour line as the screen-off display content on the display screen.
Step S1003, when the display screen enters the screen lightening state of the screen locking mode from the screen resting state, the outline lines are used as initial positions to gradually present the image, and the outline lines are faded in the presenting process of the image, so that the image is displayed when the display screen is in the screen lightening state of the screen locking mode.
Further, the display position of the contour line displayed by the display screen in the screen-saving state corresponds to the display position of the contour of the selected object on the image displayed by the display screen in the screen-locking mode in the screen-lighting state.
Exemplarily, as shown in fig. 11, when the display screen is in the screen-off state, if the mobile terminal detects a state switching event (for example, a user picks up a mobile phone or the user taps the display screen), the display screen is triggered to enter the screen-up state in the screen-locking mode from the screen-off state, and in the screen-up state in the screen-locking mode, the display screen may display a screen-locking wallpaper; in the process that the display screen displays the lock screen wallpaper from the outline line in the screen-off state to the screen-lighting state in the screen-locking mode, the lock screen wallpaper gradually appears from the outline line, in the process of appearing, the outline line gradually fades, and then the display screen displays the wallpaper image in the screen-lighting state in the screen-locking mode.
In the above embodiment, when the display screen is in the screen-off state, the outline of the selected object in the lock screen wallpaper is displayed, and when the display screen enters the screen-on state of the lock screen mode from the screen-off state, the lock screen wallpaper is gradually displayed from the outline, and the outline gradually fades in the displaying process, so that the display screen can more smoothly transit from the outline in the screen-off state to the lock screen wallpaper in the screen-on state.
Further, before step S1003, if the display position of the contour line displayed in the screen-saving state of the display screen is not consistent with the display position of the selected object contour on the image displayed in the screen-locking mode, the mobile terminal may align the display position of the contour line displayed in the screen-saving state of the display screen to the display position of the selected object contour on the image displayed in the screen-locking mode of the display screen.
That is to say, before gradually showing the lock screen wallpaper, if the outline of the screen-off state is inconsistent with the display position of the outline of the selected object of the lock screen wallpaper, in order to ensure smooth transition, the mobile terminal may first align the two and then gradually display the lock screen wallpaper.
In the above embodiments, when the computer device/third-party device generates the contour line of the selected object on the image, the background content of the image except the object can be removed through the pre-trained contour extraction algorithm, and the brush stroke for drawing the contour line is optimized, so that the contour line of the selected object can more truly outline the contour of the selected object on the image; the optimization of the contour lines can be realized by utilizing a sketch filter of the picture.
It should be understood that, although the steps in the flowcharts of fig. 1 to 11 are shown in sequence as indicated by the arrows, the steps are not necessarily performed in sequence as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise. Moreover, at least some of the steps in fig. 1 to 11 may include multiple steps or multiple stages, which are not necessarily performed at the same time, but may be performed at different times, and the order of performing the steps or stages is not necessarily sequential, but may be performed alternately or alternately with other steps or at least some of the other steps or stages.
In one embodiment, as shown in fig. 12, there is provided an apparatus for displaying a message screen, including:
