The display screen 130 is used to display the display components of the user interface. Optionally, the display screen 130 in the embodiment of the present application further has a touch function, and is configured to receive a touch operation of a user on or near the display screen by using any suitable object, such as a finger, a touch pen, and the like. The display 130 is generally disposed on a front panel of the terminal 130.

In the related art, when a user zooms in and out a picture by using a two-finger gesture, the user needs to hold the terminal with one hand and zoom in and out the picture by using the other hand, and the user cannot zoom in and out the picture under the condition that the user cannot operate the terminal with two hands, so that the application scene of zooming in and out the picture is limited.
After the image zooming method provided by the embodiment of the application is applied to an operating system or an application program, a user can trigger the terminal to enter an image zooming mode and zoom in an image through single-finger operation; when the image needs to be reduced, a user can trigger the switching of the scaling mode through single-finger operation, so that the image is reduced through the single-finger operation in the image reduction mode. Because the image zooming operation and the zooming switching operation are both single-finger operations, a user can zoom the image by using the thumb of the holding hand even under the condition that the terminal is not operated by two hands, the convenience of zooming the image is improved, and the operation difficulty of zooming the image is reduced. The following description will be made by using exemplary embodiments.
Referring to fig. 3, a flowchart of a picture scaling method according to an exemplary embodiment of the present application is shown. The present embodiment is illustrated by applying the method to the terminal 100 shown in fig. 1 or 2. The method comprises the following steps:
step 301, receiving a first operation signal for the picture in the picture browsing state, where the first operation signal is a signal triggered during a single-finger operation.
Optionally, the picture is a local picture, such as a picture in an album application, or the picture is a network picture (i.e., a picture that is not downloaded to the local), such as a picture displayed in a web page.
In a possible implementation manner, when an operation signal for a picture is received, the terminal obtains the number of operation points and the area of the operation points indicated by the operation signal, and if the number of the operation points is 1 and the area of the operation points is smaller than an area threshold (the palm touch signal is prevented from being recognized as the first operation signal), it is determined that the first operation signal is received.
The zoom mode trigger signal is an operation signal for triggering the terminal to zoom the picture. When receiving a first operation signal for the picture, the terminal further detects whether the first operation signal is a zoom mode trigger signal, and enters a picture amplification mode when the first operation signal is the zoom mode trigger signal, so that the picture is amplified according to the first operation signal.
In a possible implementation manner, the terminal detects whether the first operation signal is the zoom mode trigger signal according to the duration of the first operation signal; or the terminal detects whether the first operation signal is a zoom mode trigger signal according to the duration of the first operation signal and the operation track.
In a possible application scenario, when the magnification of a picture is too large, a user needs to reduce the enlarged picture through a reduction operation, and at this time, the user can trigger the terminal to switch from the picture enlargement mode to the picture reduction mode through a scaling mode switching operation.
Optionally, the terminal receives a second operation signal for the picture after the first operation, detects whether the second operation signal is a zoom mode switching signal, and executes the following step 304 when the second operation signal is the zoom mode switching signal.
In a possible embodiment, the terminal detects whether the second operation signal is the zoom mode switch signal according to the operation times indicated by the second operation signal.
In a possible implementation manner, when the second operation signal is a zoom mode switching signal, the terminal further detects whether a third operation signal is received, and when the third operation signal is received, performs a zoom-out process on the picture according to the third operation signal.
Optionally, the third operation signal is the same as the first operation signal. For example, when the first operation signal is a long press operation signal, the third operation signal is also a long press operation signal.
It should be noted that, in this embodiment, taking an example that the first operation signal is a zoom mode trigger signal, triggering to enter the picture zoom-in mode is described, and when the zoom mode switching signal is received, switching to the picture zoom-out mode is described, in other possible embodiments, when the first operation signal is the zoom mode trigger signal, triggering to enter the picture zoom-out mode may also be performed, and correspondingly, the terminal switches to the picture zoom-in mode when the zoom mode switching signal is received, which is not limited in this embodiment.
In an illustrative example, when the zoom mode trigger signal is a long-press operation signal, the zoom mode switch signal is a double-click signal, and the third operation signal is a long-press operation signal, as shown in fig. 4, a picture 41 is displayed on the terminal, and when the long-press operation on the picture 41 is received, the terminal enters a picture amplification mode and performs amplification processing on the picture 41; when the long press operation is stopped and the double-click operation on the picture 41 is received, the terminal is switched from the picture enlargement mode to the picture reduction mode (the picture size before enlargement is still kept); when the long press operation is received again, the terminal performs reduction processing on the picture 41.
In summary, with the image zooming method provided by the embodiment of the present application, in the image browsing state, when a first operation signal for the image is received and the first operation signal is a zooming mode trigger signal, the terminal amplifies the image according to the first operation signal; when a second operation signal after receiving the first operation signal is a zoom mode switching signal, the terminal receives a third operation signal after receiving the second operation signal to perform zoom-out processing on the picture; compared with the prior art that the image can be zoomed only by using two fingers and cannot be zoomed by using one hand, in the embodiment of the application, the image can be zoomed and zoomed out by using the operation signal triggered by the operation of the one finger, so that a user can zoom the image by using one hand under the condition that the user does not use two hands conveniently, and the convenience and the efficiency of zooming the image are improved.
In order to simplify the operation of triggering the entering of the picture scaling mode, in one possible embodiment, the scaling mode trigger signal is a long press operation signal, that is, the user can trigger the entering of the picture scaling mode by pressing a picture for a long time. The following description will be made by using exemplary embodiments.
Referring to fig. 5, a flowchart of a picture scaling method according to another exemplary embodiment of the present application is shown. The present embodiment is illustrated by applying the method to the terminal 100 shown in fig. 1 or 2. The method comprises the following steps:
The step 301 may be referred to in the implementation manner of this step, and this embodiment is not described herein again.
In this embodiment, since the zoom mode trigger signal is a long-press operation signal, in order to determine whether the received first operation signal is used for triggering image zooming, the terminal acquires the duration of the first operation signal.
In a possible implementation, the terminal receives the first operation signal, namely, starts a timer, and records the duration of the first operation signal through the timer.
In general, a long press operation on a picture may be used to trigger related operations on the picture, such as saving the picture, editing the picture, sharing the picture, and the like. In order to distinguish the above operation from the picture zooming operation, in one possible implementation, the terminal detects whether the duration of the first operation signal reaches the first duration, and displays a target operation menu (displayed on an upper layer of the picture) when the duration of the first operation signal reaches the first duration, the target operation menu being used for triggering a target operation on the picture, wherein the target operation is an operation other than the zooming operation, and the target operation is of a different type for pictures displayed in different scenes.
For example, for a picture displayed in the album application, the target operation menu includes a menu item for triggering to delete the picture, a menu item for triggering to edit the picture, and a menu item for triggering to send the picture; for the pictures displayed in the social application, the target operation menu comprises a menu item for triggering picture storage, a menu item for triggering comment pictures and a menu item for triggering picture forwarding.
Optionally, the first duration is a default duration or a duration set by a user. For example, the first duration is 1s, that is, the display of the target operation menu can be triggered by pressing the picture for 1 s.
Illustratively, as shown in fig. 6, when a long-press operation on a picture 61 is received and the long-press operation (i.e., the duration) reaches 1s, the terminal displays an operation menu 62 on an upper layer of the picture 61, where the operation menu 62 includes a save menu item, a first share menu item (for sharing the picture to an application a), and a second share menu item (for sharing the picture to an application B).
When a user wants to perform operations other than zooming operations on a picture, after the terminal displays a target operation menu, the user usually stops long-time pressing operations and clicks a menu item displayed in the target operation menu.
In the embodiment of the present application, in order to further trigger the zoom operation on the picture, the user needs to keep the long-time pressing operation after the terminal displays the target operation menu, so as to trigger the entry into the picture zoom mode through the long-time pressing operation.
Optionally, after the duration of the first operation signal reaches the first duration, the terminal continues to detect whether the duration reaches the second duration, and determines that the first operation signal is the zoom mode trigger signal when the duration reaches the second duration. And the terminal continuously displays the target operation menu in the time period from the first time length to the second time length.
In order to avoid blocking the picture by the displayed target operation menu when the picture is subsequently zoomed, when the duration of the first operation signal reaches the second duration, the terminal stops displaying the target operation menu.
Illustratively, as shown in fig. 6, after the terminal displays the operation menu 62, the user continues to hold the long press for 0.5s (i.e., the duration is 1.5s), and the terminal determines that the duration reaches the second duration (i.e., 1.5s), thereby stopping displaying the target operation menu.
Optionally, after determining that the first operation signal is the zoom mode trigger signal, the terminal may prompt in a predetermined manner, where the prompt is used to enter the image zoom mode. For example, a text prompt or a vibration prompt is displayed on the upper layer of the picture.
In one possible embodiment, the second duration is a system default. However, since the operation habits and the reflection speeds of different users are different, that is, the time required from the viewing of the target operation menu to the stopping of the long-press operation by different users is different, if the uniform second time length is set, the operation efficiency of the users may be affected or the misoperation may be caused.
For example, if the first duration is 1s and the second duration is uniformly set to 1.5s, for a user a who reflects faster operation (for example, the user a may stop the long press operation within 0.2s after viewing the target operation menu), the interval of 0.5s between the first duration and the second duration is too long; for the user B with faster reflection (for example, the user B can only reflect after viewing the target operation menu for 0.7s, and stops the long-press operation), the interval between the first time length and the second time length and 0.5s therebetween is too short, which easily causes the false triggering of zooming.
In order to avoid the above problem, the terminal may automatically adjust the second duration according to the historical trigger duration corresponding to the target operation menu (the second duration is initially set to a larger value).
Aiming at the mode of determining the second time length, in a possible implementation mode, the terminal acquires the historical trigger time length corresponding to the target operation menu, the historical trigger time length refers to the time length between the start time and the end time of the long-press operation in the process of calling out the target operation menu through the long-press operation, and the historical trigger time length is greater than the first time length; and determining a second time length according to the historical trigger time length, wherein the second time length is more than or equal to the historical trigger time length.
Optionally, the terminal calculates an average value of the historical trigger durations of each time, so as to determine the second duration according to the average value.
In an illustrative example, corresponding to a user a, a terminal obtains historical trigger durations corresponding to a target operation menu, wherein the historical trigger durations are 1.15s, 1.2s, 1.25s, 1.2s and 1.2s respectively, so that an average value 1.2s of 5 historical trigger durations is determined as a second duration; corresponding to the user B, the terminal obtains the historical trigger durations corresponding to the target operation menu, wherein the historical trigger durations are respectively 1.6s, 1.8s, 1.7s, 1.65s and 1.75s, and accordingly the average value of 1.7s of the 5 historical trigger durations is determined as the second duration.
In step 505, if the first operation signal is a zoom mode trigger signal, the picture is amplified according to the duration of the first operation signal, wherein the amplification ratio of the picture and the duration of the first operation signal are in a positive correlation.
In one possible implementation, in the picture scaling mode, the terminal performs an amplification process on the picture according to the duration of the first operation signal, wherein the amplification ratio of the picture is k × the duration of the first operation signal; or the terminal amplifies the picture according to the duration of the first operation signal and the second duration, wherein the amplification ratio of the picture is k x (the duration of the first operation signal-the second duration), and k is a preset coefficient.
Illustratively, as shown in fig. 6, the user keeps pressing the picture for 1.5s, and the terminal enlarges the picture according to the time of the long press.
Optionally, the terminal takes a picture area located in the central area of the display screen as an amplification origin to amplify the picture; or the terminal takes the operation position of the first operation signal as an amplification origin to amplify the picture.
In the process of amplifying the picture, if the picture area to be checked is located outside the display area of the display screen, the user can drag the picture area to be checked into the display area of the display screen through dragging operation. Optionally, when the first operation signal is terminated, that is, the long-press operation is terminated, if the terminal receives a dragging signal for the picture, the display position of the picture in the display screen is adjusted according to a dragging direction and a dragging distance corresponding to the dragging signal.
Illustratively, as shown in fig. 6, when the user stops long-pressing the picture 61 and drags the picture 61, the terminal adjusts the display position of the enlarged picture 61.
And 507, when a fourth operation signal after the dragging signal is received, amplifying the picture according to the fourth operation signal, wherein the fourth operation signal is a signal triggered during single-finger operation.
Furthermore, after the picture is dragged, the terminal is still in the picture amplification mode, and the user can continue to amplify the picture through operation. In a possible implementation manner, when a fourth operation signal for the picture is received, the terminal performs amplification processing on the picture according to the fourth operation signal.
Optionally, in this embodiment, the fourth operation signal is a long press operation signal, and when the duration of the fourth operation signal is greater than a duration threshold (for example, 1s), the terminal performs amplification processing on the picture according to the duration of the fourth operation signal. Wherein the magnification ratio of the picture is in positive correlation with the duration of the fourth operation signal.
Illustratively, as shown in fig. 6, after the display position of the picture 61 is adjusted by dragging, when the user presses the picture 61 again for a long time, the terminal continues to enlarge the picture 61.
Optionally, the second operation signal is a click operation signal of a predetermined number of times, where the predetermined number of times is greater than or equal to 2.
Optionally, when the fourth operation signal is terminated, the user may also switch the picture scaling mode by triggering the second operation signal.
Illustratively, as shown in fig. 6, when the user stops long-pressing and double-clicks the picture 61, the terminal switches from the picture enlargement mode to the picture reduction mode.
In step 509, if the second operation signal is the zoom mode switching signal, the picture is reduced according to the duration of the third operation signal, wherein the reduction ratio of the picture and the duration of the third operation signal are in a positive correlation.
Similar to the determination of the magnification ratio according to the duration of the first operation signal in the picture magnification mode, when the second operation signal is the zoom mode switching signal, the terminal determines the reduction ratio of the picture according to the duration of a third operation signal (such as a long press operation signal) after the second operation signal, so as to reduce the picture according to the reduction ratio.
Illustratively, as shown in fig. 6, after the user switches to the picture reduction mode by double-clicking, the picture 61 is reduced by long-pressing.
Optionally, the terminal takes a picture area located in the central area of the display screen as a reduction origin to reduce the picture; or the terminal reduces the picture by taking the operation position of the third operation signal as a reduction origin.
When it needs to be described, in the image reduction mode, the user may adjust the display position of the image through a dragging operation, and continue to reduce the image through a long-press operation after the adjustment is completed, which is not described in detail in this embodiment.
In this embodiment, the terminal amplifies the picture according to the duration of the first operation signal, and/or reduces the picture according to the duration of the third operation signal, that is, the user can zoom the picture by long-pressing, so that the operation of zooming the picture is simplified, and the efficiency of zooming the picture is improved.
In addition, the terminal distinguishes the target operation and the zooming operation on the picture according to the duration of the first operation signal, so that false triggering among different operations is avoided, and the accuracy of the zooming operation is improved.
In addition, the terminal dynamically determines the second time length according to the historical trigger time length corresponding to the target operation menu instead of adopting the uniformly set second time length, so that the trigger operation of entering the picture zooming mode conforms to the use habit of a user, the picture zooming efficiency is improved, and meanwhile, the probability of misoperation is reduced.
In another possible implementation manner, in order to distinguish the picture scaling operation from other operations performed on the picture, the terminal sets the scaling mode trigger signal triggering the entering of the scaling mode to include the target sliding operation signal and the long press operation signal after the target sliding operation signal, that is, the user needs to perform the sliding operation by using a single finger and keep the long press operation at the sliding end point to trigger the entering of the picture scaling mode. On the basis of fig. 5, as shown in fig. 7, steps 502 to 504 may be replaced with the following steps.
Optionally, when the first operation signal is a signal triggered by a single-finger operation, the terminal further obtains a sliding track indicated by the sliding operation signal in the first operation signal, and a duration of the long-press operation signal in the first operation signal, where the sliding operation signal and the long-press operation signal are continuous signals, that is, the long-press position indicated by the long-press operation signal is a sliding end point indicated by the sliding operation signal.
Further, the terminal detects whether the sliding track is matched with a target sliding track indicated by the target sliding operation, and detects whether the duration of the long-press operation signal reaches a third duration, wherein the target sliding track may be set by default or manually set by a user. Optionally, the terminal may calculate a trajectory similarity between the sliding trajectory and the target sliding trajectory, and determine that the sliding trajectory matches the target sliding trajectory when the trajectory similarity is greater than a similarity threshold (e.g., 85%).
In step 511, if the sliding track matches the target sliding track indicated by the target sliding operation and the duration of the long press operation signal reaches the third duration, it is determined that the first operation signal is the zoom mode trigger signal.
When the sliding track is matched with the target sliding track and the duration of the long press operation signal reaches a third duration (for example, 1s), the terminal determines that the first operation signal is a zoom mode trigger signal, and further performs picture zooming through steps 505 to 509.
Schematically, as shown in fig. 8, when the target sliding track is a circular track and the third duration is 1s, the user uses a finger to draw a circle on the display screen and then keeps pressing for a long time, so as to trigger entering a picture magnification mode, thereby magnifying the picture.
In order to further reduce the probability of misoperation, in a possible implementation, the terminal can start the picture zooming function provided by the method only when the terminal is held by one hand. Optionally, in each of the above embodiments, after receiving the first operation signal for the picture, the terminal obtains a current holding state of the terminal and an operation position corresponding to the first operation signal, and performs amplification processing on the picture according to the first operation signal when the first operation signal is a zoom mode trigger signal and the operation position is located in a one-handed operation area corresponding to the (current) holding state, where the holding state includes a left-handed holding state and a right-handed holding state.
In an illustrative example, the terminal acquires that the current holding state is a right-hand holding state, and determines a one-hand operation area (which may be preset or generated according to a user's usage habit) corresponding to a thumb of a right hand in the right-hand holding state, and when the operation position of the first operation signal is located in the one-hand operation area corresponding to the thumb of the right hand and the first operation signal is a zoom mode trigger signal, the terminal enters the picture zoom mode; otherwise, the terminal will respond to the first operation signal according to conventional response logic.
