Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, an embodiment of the present invention provides a method for adjusting display of a preview image, including:
it should be noted that the sliding input may be a sliding operation through a target control, and the target control moves along with a sliding track, for example, an initial position of the sliding track of the user is at a display position of the target control, and in a sliding process of the user, the target control moves along with the sliding track; or the sliding input may be a dragging operation of the user dragging the target control.
it should be noted that the target area refers to a preview image of a specific area in the shooting preview interface; the target area is associated with the display position of the target control, that is, the target area is determined by the target control.
It should be noted that the embodiment of the present invention mainly achieves adjusting the ratio of the display view angles of the preview images on the shooting preview interface, and specifically, the target control is displayed on the shooting preview interface.
Specifically, the embodiment of the present invention is mainly applied to the ultra-wide-angle photographing mode, and the photographing preview interface is an ultra-wide-angle photographing preview interface.
It should be noted that the target control is mainly used for performing a condition of a viewing angle, in order to increase the variety of adjustment of the preview image on the shooting preview interface, a shooting mode adjustment control may also be added, and the target control may be displayed in the same area as the shooting mode adjustment control, or may be displayed in different areas of the shooting preview interface independently.
It should be further noted that, in the case that the terminal has the photographing mode adjustment control, the preview image display adjustment method further includes:
receiving input to the photographing mode adjustment control; and responding to the input, adjusting a photographing mode of the preview image in the photographing preview interface, and displaying the adjusted preview image on the photographing preview interface.
It should be noted that the photographing mode may include: a beauty mode, a filter mode, a dynamic photo mode, a high definition dynamic range image (HDR) mode, etc.
In other words, in this way, the user can not only adjust the display view angle ratio (i.e., the view angle ratio) of the preview image on the shooting preview interface, but also adjust the shooting mode of the preview image, and can shoot ultra-wide-angle pictures in various forms.
When the embodiment of the present invention is implemented, first, an ultra-wide-angle shooting preview interface is entered, it should be noted that when the terminal enters the shooting preview interface, the angle of view of the preview image may be displayed according to a ratio (that is, a default ratio of the display angle of view) set by a user in advance, or the angle of view of the preview image may be displayed according to a ratio of the display angle of view set by the user before according to a user requirement, and the following describes the embodiment of the present invention in detail from these two angles, respectively.
Opening an ultra-wide-angle shooting preview interface, and displaying the display visual angle of the preview image according to the default display visual angle
In this case, before step 101, the method further includes:
receiving a third input of the user; and responding to the third input, and displaying a super-wide-angle shooting preview interface according to a preset display visual angle proportion, wherein a target control is displayed on the super-wide-angle shooting preview interface.
It should be noted that the preset display view angle ratio refers to a default display view angle ratio, that is, each time the super-wide shooting preview interface is opened, the preview image will be displayed using the default display view angle ratio.
It should be noted that the third input may be a slide input, a press input, a click input, a long press input, or the like, that is, the third input is an operation performed by the user on the interface of the terminal to call up the shooting preview interface, and specifically, the user may enter the ultra-wide-angle shooting preview interface through a slide operation, a press operation, a click operation, a long press operation, or the like.
For example, as shown in fig. 2, on the camera preview interface, the user uses two fingers to perform a sliding operation in a downward arrow direction in the left diagram, the terminal performs interface switching to display the ultra-wide-angle shooting preview interface, as shown in the right diagram in the figure, the target control 10 and the shooting mode adjustment control 20 are displayed on the ultra-wide-angle shooting preview interface, both of which are displayed in the same area, the target control 10 is represented by a solid circle, and the shooting mode adjustment control 20 is represented by a dotted circle, and the adjustment of the four shooting modes, i.e., the beauty mode, the filter mode, the dynamic photo mode, and the HDR mode, can be implemented in the figure. In this case, the preview image on the super-wide-angle shooting preview interface is in the default display view angle ratio, that is, the user displays the preview image in the default display view angle ratio when entering the super-wide-angle shooting preview interface for multiple times under different conditions.
And secondly, when the super-wide-angle shooting preview interface is opened, displaying the view angle of the preview image according to the proportion of the display view angle set by the user before
In this case, before step 101, the method further includes:
receiving a third input of the user; and responding to the third input, determining a first proportion of a display visual angle of the shooting preview interface, wherein the acquisition time of the first proportion is earlier than the input time of the third input, and the time interval between the acquisition time of the first proportion and the input time of the third input is minimum, and displaying the shooting preview interface according to the first proportion.
It should be noted that the third input may be a slide input, a press input, a click input, a long press input, or the like, that is, the third input is an operation performed by the user on the interface of the terminal to call up the shooting preview interface, and specifically, the user may enter the ultra-wide-angle shooting preview interface through a slide operation, a press operation, a click operation, a long press operation, or the like.
It should be noted that, in this case, the terminal needs to store the ratio of the display viewing angle, for example, the terminal may store the ratio of the display viewing angle adjusted last time according to the setting of the user; it should also be noted that the terminal may also collect the user's needs in real time, and store the proportion of one display viewing angle most used (or most interesting) by the user.
For example, as shown in fig. 3, on the camera preview interface, the user uses two fingers to perform a sliding operation along the left arrow direction in the left diagram, the terminal performs interface switching, and displays an ultra-wide-angle shooting preview interface, as shown in the right diagram in the figure, a target control 10 and a shooting mode adjustment control 20 are displayed on the ultra-wide-angle shooting preview interface, both of which are displayed in the same area, the target control 10 is represented by a solid circle, and the shooting mode adjustment control 20 is represented by a dotted circle, and the adjustment of four shooting modes, i.e., a beauty mode, a filter mode, a dynamic photo mode, and an HDR mode, can be implemented in the figure. In this case, the preview image on the super-wide-angle shooting preview interface is the ratio of the display view angle adjusted last time, that is, when the user enters the super-wide-angle shooting preview interface for multiple times under different conditions, the preview image is displayed according to the ratio of the previous display view angle.
It should be noted that, in this way, the operation time of the user can be reduced by directly entering the mode of setting the ratio of the viewing angle, and the user can perform the photographing operation by entering the super-wide angle photographing preview interface.
In both cases, the third input may be distinguished by different user operations, such as a sliding operation, a pressing operation; it is also possible to use different operating characteristics for distinguishing, for example, the user uses a sliding operation in both cases, only the direction of the sliding operation is different, i.e. different cases are distinguished by different sliding directions.
It is further noted that, the adjusting of the size of the view angle of the target area in the shooting preview interface includes at least one of the following:
zooming out or magnifying the viewing angle;
enlarging the visual angle of a target area in a shooting preview interface;
and reducing the visual angle of the target area in the shooting preview interface.
For example, as shown in fig. 4, a solid circle on the ultra-wide-angle shooting preview interface represents the target control 10, and when the user drags the solid circle to rotate clockwise along an arrow in the figure, it represents that an operation of enlarging the angle of view is performed, and at this time, as shown in the right-side figure, the ratio of the angle of view of the preview image on the ultra-wide-angle shooting preview interface becomes large, and the ratio of the object in the preview image on the ultra-wide-angle shooting preview interface becomes small; when the user drags the solid line circle to rotate counterclockwise, the operation of reducing the angle of view is performed, and at this time, the ratio of the angle of view of the preview image on the ultra-wide-angle shooting preview interface becomes smaller, and the ratio of the object in the preview image on the ultra-wide-angle shooting preview interface becomes larger.
In the embodiment of the present invention, the adjustment of the photographing mode may also be implemented, for example, as shown in fig. 5, the photographing mode adjustment control 20 is represented by a dashed circle, and the adjustment of four photographing modes, i.e., a beauty mode, a filter mode, a dynamic photo mode, and an HDR mode, may be implemented, where the uppermost side of the photographing mode adjustment control 20 is regarded as the mode selected state, the left side indicates that the preview image is in the beauty mode, and if the user wants to adjust the photographing mode, the photographing mode that needs to be adjusted is pressed and adjusted to the selected state, the user drags the photographing mode adjustment control 20 to rotate the photographing mode in the direction of the arrow in the drawing, and adjusts the filter mode to the selected state, as shown in the right side drawing, at this time, the adjustment of the photographing mode is completed.
It should be further noted that, after the user performs a scale adjustment of the display viewing angle once, the adjustment may not meet the use requirement of the user, in the embodiment of the present invention, the cancellation of the adjustment may be implemented, specifically, the implementation process is as follows:
receiving a second input to the target control, and canceling the kth adjustment of the view angle of the target area in the shooting preview interface in response to the second input;
wherein the adjustment time of the k-th adjustment is earlier than the input time of the second input and has a minimum time interval with the input time of the second input; k is a positive integer.
It should be noted that the second input may be a slide input, a press input, a click input, a long press input, or the like, that is, the second input is an operation of canceling the adjustment performed by the user on the interface of the terminal, and specifically, the user may cancel the adjustment of the view angle ratio through a slide operation, a press operation, a click operation, a long press operation, or the like.
It should be noted that, in the embodiment of the present invention, previous adjustment is cancelled, for example, when a user performs adjustment of the size of a view angle once, but this adjustment does not meet the use requirement of the user, the user may cancel the current adjustment by performing a sliding operation on the target control.
For example, as shown in fig. 6, fig. 6 includes a target control 10 and a photographing mode adjustment control 20, which are displayed in the same area, the target control 10 is represented by a solid circle, the photographing mode adjustment control 20 is represented by a dotted circle, and the solid line circle is positioned inside the dotted line circle, when the user performs the scale adjustment once, the scale of the display viewing angle is enlarged and adjusted, however, the user is not satisfied with the current adjustment, and wants to return to the state before adjustment, at this time, the user drags the solid line circle in the drawing to slide it along the left arrow direction, and slides it outside the dotted line circle, at this time, the terminal cancels the last adjustment of the ratio of the viewing angle, the ratio of the viewing angle returns to the state before adjustment, as shown in the right-hand side of the figure, the view angle scale is reduced, and the scale of the object in the preview image on the ultra-wide-angle shooting preview interface is increased. It should be noted that, if the user wants to return to the proportional state before the revocation after the revocation in fig. 6 is performed, the solid line circle may be dragged to slide to the right side and slide outside the dotted line circle, and at this time, the proportion of the angle of view returns to the state before the revocation, that is, the proportion of the angle of view of the preview image is enlarged on the original basis, and the proportion of the object in the preview image on the super-wide-angle shooting preview interface becomes smaller.
It should be further noted that, in the embodiment of the present invention, when the angle of view of the shooting preview interface is adjusted, the preview image on the whole shooting preview interface may be adjusted, that is, the target area is the whole shooting preview interface, or a part of the preview image is adjusted, that is, the target area is a part of the shooting preview interface, which will be described below separately.
Firstly, adjusting the whole shooting preview interface
Specifically, in this case, the specific implementation manner of step 102 is:
acquiring the sliding direction and the sliding track of the sliding input;
and adjusting the size of the visual angle of the target area based on the sliding direction and the sliding track of the sliding input.
It should be noted that, in this case, the adjustment of the whole shooting preview interface is realized by performing sliding operations in different sliding directions on the target control, for example, when the user performs clockwise rotation on the target control, the angle of view of the whole shooting preview interface is enlarged, as shown in fig. 4 specifically; for example, when the user performs counterclockwise rotation on the target control, zooming out of the angle of view of the entire shooting preview interface is performed.
It should be noted that, by this way, the adjustment of the view angle of the whole shooting preview interface can be realized, so that the view angles of different areas have the same view angle, and a user can shoot images with the same view angle conveniently.
Secondly, adjusting the local shooting preview interface
Specifically, in this case, the specific implementation manner of step 102 is:
updating the display position of the target control in response to the sliding input;
and adjusting the visual angle size of a target area of a preset range including the final display position of the target control.
Specifically, in this case, the position of the target control is moved, and the preset range of the final display position of the target control may be set in advance by the user.
Specifically, the manner of adjusting the size of the view angle of the target area in the preset range including the final display position of the target control is as follows: acquiring the coverage area of the target control, and adjusting the visual angle of a target area in a preset range including the final display position of the target control based on the coverage area of the target control;
wherein the coverage area is positively correlated with the viewing angle size of the target area.
It should be noted that, in this case, the size of the view angle is adjusted according to the coverage area of the target control, that is, different coverage areas correspond to different view angle proportions; in the embodiment of the invention, the larger the coverage area is, the larger the visual angle of the target area is, and the smaller the coverage area is, the smaller the visual angle of the target area is.
In this way, the user drags the target control to a position of the preview image when the user wants to adjust the view angle of the position, and the view angle of the target area corresponding to the position is adjusted according to the coverage area of the target control.
For example, after the user presets to drag the target control 10 to a predetermined area, it is performed that the ratio of the viewing angles of the target area including the predetermined area is adjusted according to the coverage area of the target control, as shown in fig. 7, the target control 10 is represented by a solid circle, the user drags the solid circle to a predetermined position of the preview image along the arrow direction, the proportion of the viewing angle of the target area containing the predetermined position is adjusted according to the coverage area of the target control 10, for example, the coverage area of the target control 10 in the left side of fig. 7 is shown as a dashed box, the view angle ratio of the target area including the predetermined area where the target control 10 is located is adjusted according to the coverage area of the target control 10, and after the adjustment, as shown in the right side of fig. 7, the view angle of the target area is increased, that is, the ratio of the object in the preview image on the super-wide-angle shooting preview interface is decreased.
It should be further noted that the user may also adjust the view angle ratio of the target area by adjusting the coverage area of the target control, for example, if the user enlarges the coverage area of the target control, the view angle ratio of the target area is enlarged; and if the user reduces the coverage area of the target control, reducing the proportion of the visual angle of the target area.
For example, after the user presets dragging the target control to a preset area, the coverage area of the target control is reduced, the view angle of the target area is scaled down, as shown in fig. 8, the target control 10 is represented by a solid circle, and the user drags the solid circle to a predetermined position of the preview image, adjusts the area of the solid circle, the scale of the angle of view at the predetermined position is made to decrease as the area of the solid line circle becomes smaller, for example, in the left diagram of fig. 8, the coverage area of the target control 10 is adjusted from the original circle to an ellipse, the coverage area is reduced, the target area including the preset range of the final display position of the target control 10 before the adjustment is displayed without an object, after the coverage area of the target control 10 is reduced, the view angle scale is also reduced, as shown in the right-hand diagram of fig. 8, the target area indicated by the target control 10 in the right-hand drawing has been displayed with the object 1.
It should be noted that, in this case, different coverage areas of the target control correspond to different view angle proportions, for example, the coverage area of the target control includes the following reference values: 0.25 square centimeter, 1 square centimeter, 2.25 square centimeter, 4 square centimeter, respectively corresponding to the visual angle ratio of 0.75, 1, 1.25, 1.5, adjusting the coverage area to different sizes, then the visual angle ratio is correspondingly adjusted to the corresponding ratio size.
It should be noted that the view angle ratio of the target area can be rapidly adjusted to the specified size according to the coverage area of the target control, so that the view angle ratio of the target area can be conveniently adjusted.
It should be further noted that when the user does not need to perform super-wide-angle photographing, the terminal needs to exit the super-wide-angle photographing preview interface, in this case, the terminal may capture a specific operation performed by the user on the super-wide-angle photographing preview interface, and then return to the camera preview interface, for example, as shown in fig. 9, on the super-wide-angle photographing preview interface, the user performs a sliding operation in a direction of a downward arrow in the left diagram using two fingers, and the terminal performs interface switching to display the camera preview interface, as shown in the right diagram in fig. 9.
It should be noted that, by this way, the adjustment of the view angle size of the local area at any position of the shooting preview interface can be realized, so that one image shot by the user has different view angles, and the layering of the shot image is increased.
According to the embodiment of the invention, the proportion and the photographing mode of the visual angle are adjusted on the ultra-wide-angle photographing preview interface, so that the ultra-wide-angle photographing is conveniently carried out by a user according to the requirement, and the photographing experience of the user is improved.
