Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0028] The display method, display device, electronic device and readable storage medium provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.

[0029] Please refer to Figure 1 , Figure 1 A flow chart of a display method provided in an embodiment of the present application. Figure 1 As shown, an embodiment of the present application provides a display method, which is applied to an electronic device. The display method includes the following steps:

[0030] Step 101: Capture and display a preview image.

[0031] Optionally, before step 101, the display method further includes: receiving a start input from the user, that is, step 101 is performed in response to the start input, wherein the first input may be an input for starting the makeup mirror function of the electronic device, for example, the first input is a click input, a long press input, a drag input, etc. of the makeup mirror control on the camera interface, or the start input may also be an input for opening a makeup mirror application, etc. The electronic device will respond to the first input, turn on the makeup mirror function, or turn on the makeup mirror application, capture a preview image through a default camera and display it on the screen of the electronic device, wherein the default camera is usually the front camera of the electronic device, and the preview image is dynamically updated in real time.

[0032] Please refer to Figure 2 , Figure 2 Schematic diagram of a preview image provided in an embodiment of the present application. Figure 2 As shown, the electronic device displays the preview image captured by the camera in full screen on its screen.

[0033] Step 102: receiving a first input of a first position in the preview image;

[0034] Step 103: In response to the first input, an image of a first area is displayed in a first window with enlarged image, and an image of a second area is displayed in a second window with enlarged image, wherein the first area is determined according to the first position, the second area is determined according to the second position, the second position is symmetrical with the first position about an axis of symmetry of the face image, and the axis of symmetry is determined according to at least one pair of feature points that are symmetrically positioned in the preview image.

[0035] In the above step 102, optionally, the first input can be an input of clicking or long pressing the first position in the preview image displayed on the screen of the electronic device, that is, the first input can be an input on the screen of the electronic device; the first input can also be a gesture input, for example, the first input is a gesture input in which the user's finger points to the user's real face or touches the user's real face, and the first input will also have a corresponding user finger image in the preview image, which is equivalent to a mirror image relationship. Therefore, the user can select any area of ​​the face that he wants to enlarge and view through the first input, so that the user can observe the facial details.

[0036] Please refer to Figure 3 , Figure 3 This is a schematic diagram of the first input provided in the embodiment of the present application. Figure 3 As shown, when the user points to a certain area of ​​the face with the user's finger 301, the electronic device can detect the user's finger 301 through object recognition technology or gesture recognition technology, and then determine the position pointed to by the user's finger 301 or the position touched by the user's finger 301 as the first position.

[0037] In step 103, if the electronic device receives the above-mentioned first input, it will respond to the first input, determine the first area according to the first position, and, according to the symmetry axis of the preview image, determine the second position in the preview image that is symmetrical with the first position about the symmetry axis, and then determine the second area according to the second position. After that, the image of the first area and the image of the second area can be enlarged and displayed respectively through two windows, and the images of the first area and the second area can be enlarged and displayed through two enlarged windows, so that the user can conveniently and clearly view the details of any position in the preview image, thereby improving the user's experience in makeup and other scenarios; and the enlarged areas in the two windows are symmetrical, so that it is convenient for the user to compare and view, meet the user's demand for symmetrical makeup effects, and improve the user experience.

[0038] In some embodiments of the present application, the axis of symmetry can be determined based on at least one pair of symmetrically positioned feature points in the preview image. For example, the preview image includes a face image, and the feature points include face feature points. Face feature points can be extracted from the collected preview image, and then at least one pair of symmetrically positioned face feature points can be further determined. Finally, the axis of symmetry of the preview image can be determined based on the at least one pair of symmetrically positioned face feature points by using a fitting straight line or other method.

[0039] Therefore, in the embodiment of the present application, by continuously capturing and displaying the preview image, and selecting the first position through the first input of the target position in the preview image, and then obtaining the images of the first area and the second area in the preview image to be enlarged according to the first position, two enlarged windows are finally displayed, and the images of the first and second areas are enlarged and displayed in the two windows respectively, so that the enlarged image of any area in the preview image can be conveniently viewed, and the local details are clearly displayed, which enriches the makeup mirror function and improves the user experience; and, the dual-window enlarged display of the images of the first area and the second area in a symmetrical relationship can facilitate the user to compare and view, meet the user's demand for symmetrical makeup effects, and improve the user experience.

[0040] In some embodiments of the present application, the first window and the second window can be displayed on top of the screen of the electronic device, that is, the layers where the first window and the second window are located are located above the layer where the face image is located. The first window and the second window can be displayed at the location where the first area and the second area are located in the preview image, or can be displayed in the face display area other than the first area and the second area in the preview image, or can be displayed outside the face display area of ​​the preview image, so that the user can still check the complete face.

[0041] In some other embodiments of the present application, the magnification of the images of the first area and the second area may be a preset magnification, and the preset magnification may be pre-set by a user or a default value may be used.

[0042] In some embodiments of the present application, the step of magnifying and displaying an image of the first area in the first window and magnifying and displaying an image of the second area in the second window comprises:

[0043] When a first characteristic part is detected within a first preset area with the first position as the center, and a second characteristic part corresponding to the first characteristic part is detected within a second preset area with the second position as the center, an image of the first area is displayed in a first window at a preset magnification, and an image of the second area is displayed in a second window at a preset magnification, wherein the first area includes the first characteristic part and the second area includes the second characteristic part.

[0044] That is, after receiving the first input of the first position in the preview image, it is possible to detect whether the first characteristic part exists within the first preset area centered on the first position, and to detect whether the second characteristic part corresponding to the first characteristic part exists within the second preset area centered on the second position, and then determine the specific shape, size, etc. of the first area and the second area according to the detection results. Exemplarily, if the first characteristic part is detected within the first preset area centered on the first position, and the second characteristic part corresponding to the first characteristic part is detected within the second preset area centered on the second position, then the area containing the first characteristic part can be determined as the first area, and the area containing the second characteristic part can be determined as the second area. Thus, the first area and the second area can be determined in combination with the outline of the specific characteristic part that the user wants to zoom in and view, thereby avoiding the part that the user does not pay attention to from being zoomed in, and the characteristic part can be displayed more prominently.

[0045] Among them, the first preset area range can be a circular area range, a rectangular area range, etc. centered at the first position, and its specific size and other parameters can be set according to actual needs, and the second preset area range is the same.

[0046] Please refer to Figure 4 , Figure 4 This is a schematic diagram of the first preset area range provided in the embodiment of the present application. Figure 4 As shown, in some embodiments of the present application, the position where the user's finger 301 contacts the face is the first position, and the first preset area range 302 is a rectangular area range of a preset size centered on the first position.

[0047] In the embodiment of the present application, optionally, the first characteristic part and the second characteristic part can be detected and identified using facial feature recognition technology, object recognition technology, etc. The first characteristic part and the second characteristic part can be facial features such as eyes, or certain parts with contours in the face, such as the location of cheekbones, eyebrows, freckles, acne marks, etc.

[0048] In some embodiments of the present application, the shape and size of the first area and the first window are determined according to the contour of the first characteristic part, and the shape and size of the second area and the second window are determined according to the contour of the second characteristic part.

[0049] Since the method of framing the target area with a fixed circle, rectangle or other shape usually selects some areas that the user does not want to pay attention to and then enlarges and displays them, the part that the user wants to zoom in on cannot be effectively highlighted. Therefore, in an embodiment of the present application, if the first characteristic part is detected within the first preset area centered on the first position, the first area can be determined according to the outline of the first characteristic part, that is, the first characteristic part is located within the first area, and the shape and size of the first area are determined according to the detected outline of the first characteristic part. For example, the area enclosed by the outline boundary of the first characteristic part is used as the first area, or the area enclosed by the smallest circle or the smallest rectangle that can frame the outline of the first characteristic part is used as the first area, and the second area is the same. Therefore, the size of the first area and the second area can be determined in combination with the outline of the specific characteristic part that the user wants to zoom in on, thereby avoiding the part that the user does not pay attention to from being enlarged, and the characteristic part can be more prominently displayed.

[0050] Please refer to Figure 5 , Figure 5 Schematic diagram of the first window and the second window provided in the embodiment of the present application. Figure 5 As shown, in some embodiments, after receiving a first input of a first position in the preview image, it is possible to detect whether a first characteristic part exists within a first preset area centered on the first position. Figure 5 That is, there is a first characteristic part, the left eye, and then according to the symmetry relationship, it is detected whether there is a second characteristic part corresponding to the first characteristic part within a second preset area centered on the second position. Figure 5 That is, if there is a right eye in the second characteristic part, the image of the left eye in the first characteristic part can be displayed in the first window, and the image of the right eye in the second characteristic part can be displayed in the second window. Optionally, the shapes of the first window and the second window can be determined according to the contours of the first characteristic part and the second characteristic part.

[0051] In some embodiments of the present application, the second area is composed of a third preset area range centered on the center point of the second characteristic part. Specifically, taking the preview image containing a face image as an example, considering that parts such as eyes in the face image are not completely symmetrical, therefore, when the first position is symmetrically moved to the second position through the axis of symmetry, and the second characteristic part corresponding to the first characteristic part is detected within the second preset area range centered on the second position, the second characteristic part may not be at the center of the second preset area, and then in the second area directly determined according to the second position, the second characteristic part may not be at the center of the second area, therefore, after the second characteristic part is detected according to the second position, the center point of the second characteristic part can be obtained according to the characteristic points on the second characteristic part, and then the second area is formed by the third preset area range centered on the center point of the second characteristic part, so that the second characteristic part in the second area can be in the central position, thereby realizing the correction of the enlarged content in the corresponding second window, which is more conducive to user viewing.

[0052] In some embodiments of the present application, after receiving a first input of a first position in the preview image, the method further includes:

[0053] When a first characteristic part is detected within a first preset area with the first position as the center, and a second characteristic part corresponding to the first characteristic part is not detected within a second preset area with the second position as the center, an image of the first area is displayed in a first window with enlargement, and the first area is determined according to the first position;

[0054] receiving a second input from a user on the first window;

[0055] In response to the second input, a third window is displayed, the third window being used to magnify an image of a third area, the third area being determined according to the second input.

[0056] In this embodiment, if a first characteristic part is detected within a first preset area with the first position as the center, and a second characteristic part corresponding to the first characteristic part is not detected within a second preset area with the second position of the symmetry axis with respect to the preview image, it means that there is no symmetrical part with the first characteristic part, and then a window, namely the first window, can be displayed by default at this time, so that the image of the first area determined according to the first position is magnified and displayed in the first window. At this time, if the user wants to add a window, the user can make a second input to the first window, for example, the second input is an input of long pressing and dragging the first window, then the electronic device will respond to the second input after receiving the second input, create and display a third window, the magnified content in the third window is the image of the third area, and the third area can be determined according to the second input, for example, the second input is an input of long pressing and dragging the first window to the third position, then the third area is composed of a fourth preset area with the third position as the center.

[0057] In some other embodiments of the present application, after the image of the first area is magnified and displayed in the first window, and the image of the second area is magnified and displayed in the second window, the method further includes:

[0058] receiving a third input from a user on a target window, where the target window is the first window or the second window;

[0059] In response to the third input, the display positions or target parameters of the first window and the second window are synchronously adjusted, and the target parameters include at least one of a display size, a display shape, and a magnification.

[0060] Since the shape and / or size of the window is determined according to the shape of the corresponding area, etc., there may be a situation where the shape, size, display position, etc. of the window do not meet the actual needs of the user. Therefore, the user can adjust the display position or target parameter of the window through the third input to the target window. In this embodiment, since the first area corresponding to the first window and the second area corresponding to the second window are symmetrical about the axis of symmetry, the user can realize the synchronous linkage operation of the two windows. Exemplarily, if the user receives the third input to the target window, optionally, the third input can be an input of clicking the control of the target window, an input of long pressing the target window, an input of dragging the target window in different directions with two fingers, or the third input is a gesture input, the gesture does not contact the screen of the electronic device, and the gesture can be pre-set, then the electronic device will respond to the third input, synchronously adjust the display position or target parameter of the first window and the second window, wherein the target parameter includes at least one of the display size, display shape, and magnification.

[0061] In some embodiments of the present application, the synchronously adjusting the display positions or target parameters of the first window and the second window includes at least one of the following:

[0062] Synchronously adjusting the display sizes of the first window and the second window to a target size, where the target size is determined according to the third input;

[0063] Synchronously adjusting the display shapes of the first window and the second window to a target shape, where the target shape is determined according to the third input;

[0064] Synchronously adjusting the magnifications corresponding to the first window and the second window to a target magnification, where the target magnification is determined according to the third input;

[0065] The display positions of the first window and the second window are synchronously moved.

[0066] That is to say, no matter whether the third input is made to the first window or the second window, the first window and the second window can be synchronously controlled. Specifically, the display size of the first window and the second window can be adjusted to the target size, that is, the window size is adjusted; the magnification of the first window and the second window can be adjusted to the target magnification, that is, the magnification of the image in the window is adjusted; the display shape of the first window and the second window can be adjusted to the target shape, that is, the window shape is adjusted; or the display position of the first window and the second window can be synchronously moved, etc.

[0067] Please refer to Figure 6 , Figure 6 A schematic diagram of synchronously reducing the size of the first window and the second window provided in an embodiment of the present application. Figure 6 As shown, in some embodiments of the present application, if a third input is received from the user to reduce the size of either the first window 3031 or the second window 3032, the electronic device will respond to the third input and reduce the size of both the first window 3031 and the second window 3032. Figure 6 Compared to Figure 5 In particular, the sizes of the first window 3031 and the second window 3032 have been reduced.

[0068] In some embodiments of the present application, optionally, the user can pre-set a first preset gesture condition for adjusting the magnification, for example, the gesture for increasing the magnification is set to an angle formed by two user fingers greater than a preset angle threshold, and the gesture for decreasing the magnification is set to an angle formed by two user fingers less than a preset angle threshold, or, the gesture for increasing the magnification is set to a single user finger pointing to a first preset direction, and the gesture for decreasing the magnification is set to a single user finger pointing to a second preset direction, and so on. Then, when it is detected that the gesture of the user's finger in front of the face satisfies the first preset gesture condition, the target window corresponding to the gesture is determined. For example, if the electronic device currently displays only one window, the window is the target window. If the electronic device currently displays at least two windows, the window displaying the user's finger can be determined as the target window. Optionally, if at least two windows contain the user's finger, the window containing the most user fingers can be determined as the target window corresponding to the gesture, thereby solving the problem of not being able to accurately identify the window to be adjusted by the user.

[0069] In other embodiments, for example, the user can pre-set a second preset gesture condition for adjusting the window size, thereby, without the need to input on the screen of the electronic device, the magnification of the images displayed in the first window and the second window can be conveniently adjusted through gestures, so that the user can better view the details of the corresponding area. For example, the gesture for increasing the window size is set to an angle formed by two non-adjacent fingers of three user fingers that is greater than a preset angle threshold, and the gesture for decreasing the window size is set to an angle formed by two non-adjacent fingers of three user fingers that is less than a preset angle threshold, or, the gesture for increasing the window size is set to a single user finger pointing to a third preset direction, and the gesture for decreasing the window size is set to a single user finger pointing to a fourth preset direction, and so on. Then, when it is detected that the gesture of the user finger in front of the face satisfies the second preset gesture condition, the target window corresponding to the gesture is determined. For example, if the electronic device currently displays only one window, this window is the target window. If the electronic device currently displays at least two windows, the window displaying the user finger can be determined as the target window. Optionally, if at least two windows contain user fingers, the window containing the most user fingers can be determined as the target window corresponding to the gesture. This can solve the problem of not being able to accurately identify the window to be adjusted by the user.

[0070] In some embodiments of the present application, optionally, the first window is displayed over the detected first characteristic part, and the second window is displayed over the detected second characteristic part. That is to say, the display position of the first window for magnified display is located above the first characteristic part detected near the first position, and the transparency of the first window can be set to 0, that is, the first characteristic part is completely covered and replaced by the first window, and the second window is the same. As a result, it is convenient for users to directly view the first characteristic part and the second characteristic part in the first window and the enlarged images of the first characteristic part and the second characteristic part in the second window at the location where the first characteristic part and the second characteristic part are located.

[0071] In some other embodiments of the present application, after the image of the first area is magnified and displayed in the first window, and the image of the second area is magnified and displayed in the second window, the method further includes:

[0072] When the overlapping area of ​​the first window and the second window is greater than a preset area threshold, the first window and the second window are combined and displayed as a fourth window, and the fourth window is used to enlarge and display images of the first area and the second area.

[0073] After the first window and the second window are displayed, for example, after the sizes of the first window and the second window are enlarged, the display areas of the first window and the second window may overlap. Therefore, if the overlapping area of ​​the first window and the second window is greater than a preset area threshold, the first window and the second window can be combined and displayed as one window, i.e., the fourth window, and the fourth window is used to enlarge and display the images of the first area and the second area. In this way, the problem of the two windows blocking each other and affecting the user's viewing can be avoided.

[0074] Of course, in some optional implementations, if the overlapping area of ​​the first window and the second window is greater than a preset area threshold, either the first window or the second window may be removed, that is, only one of them is retained to avoid affecting the user's viewing of facial details.

[0075] In some embodiments of the present application, after receiving the second input of the user on the first position in the face image, the method further includes:

[0076] While displaying the image of the first area in the first window at a preset magnification, and displaying the image of the second area in the second window at a preset magnification, a first display processing is performed on other display areas in the face image except the first window, the first area, the second window and the second area, wherein the first display processing includes any one of hiding processing, blurring processing and replacing processing.

[0077] In this embodiment, in order to enable the user to better view the details of the first area and the second area, make the details of the first area and the second area more prominent, and avoid being disturbed by the pictures that other users do not want to pay attention to, the first display processing can be performed on the other display areas except the first window, the first area, the second window and the second area in the face image displayed by the electronic device, wherein the first display processing can adopt Gaussian blur and other technologies, specifically, it can be any one of hiding processing, blurring processing and filling processing; the so-called hiding processing is to hide the image of the corresponding area and not display it, such as cropping, the so-called blurring processing is to change the brightness, color, etc. of the image of the corresponding area from dark to light, and blur the image, and the so-called filling processing is to fill the image of the corresponding area with a solid color background, such as a black background, a white background, a gray background, etc.

[0078] In some further embodiments of the present application, after the image of the first area is magnified and displayed in the first window, and the image of the second area is magnified and displayed in the second window, the method further includes:

[0079] Record and save the display screen in the first window and / or the second window.

[0080] The first window or the second window recorded and saved is a window whose screen is dynamically updated in real time. By recording and saving the display screen in the first window and / or the second window, a makeup video file of the first area and / or the second area can be obtained, and the makeup video file saves the makeup steps of the user for the first area and / or the second area, so that the user can share the makeup video file, such as sending it to other users, uploading it to a target social platform, etc.

[0081] In some embodiments of the present application, after the image of the first area is magnified and displayed in the first window, and the image of the second area is magnified and displayed in the second window, the method further includes:

[0082] receiving a fourth input from a user on a target window, where the target window is the first window or the second window;

[0083] In response to the fourth input, the enlarged display of the target window is cancelled.
