[0074] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.

[0075] The embodiments of the present application provide a display method, which is applied to electronic devices, such as computers, tablets, notebooks, computers, cameras, smart phones and the like.

[0076] The embodiments of the present application provide a display method. Referring to FIG. 1, an optional flowchart of the display method provided by the embodiments of the present application is shown. The steps shown in FIG. 1 will be described as follows:

[0077] S101, in response to a highlight gesture of a user for a display area, highlighting a target sub-area in the display area, wherein a gesture trajectory of the highlight gesture indicates the target sub-area.

[0078] In the embodiments of the present application, when the user needs to highlight a target sub-area in the display area during the process of playing the display area by the electronic device, the user can show a highlight gesture for the target sub-area in the display area. The electronic device acquires video data including the highlight gesture of the user, determines the target sub-area according to the gesture trajectory of the highlight gesture in the video data, and highlights the target sub-area.

[0079] The display area can include a file page area, a presentation area, a video scene area and the like which the user needs to display. The target sub-area can be one or more sub-areas including key content, key targets or key scene areas in the display area.

[0080] For example, the user can write or display information on a display board. The display area can refer to a region corresponding to the display board. The display board refers to a flat surface that can be used for writing or presenting information. For example, the display board can include but is not limited to a whiteboard, a transparent board, a translucent board, a blackboard, a white wall, an electronic whiteboard, wallpaper, a screen, a writable glass surface, a display and the like.

[0081] The highlight gesture can include any gesture used by the user to determine the target sub-region in the display area, and can include, for example, a non-contact or contact gesture, such as a click gesture, an OK gesture, a double-click gesture, an arc trajectory gesture, a V-shaped trajectory gesture, a rectangular trajectory gesture, a line trajectory gesture, and the like.

[0082] In the embodiments of the present application, when there is only one target sub-region, the target sub-region can be highlighted in the current picture. When there are multiple target sub-regions, the multiple target sub-regions can be highlighted in different regions of the current picture. In the embodiments of the present application, the electronic device can magnify and display the target sub-region in the display area, and / or visually enhance the display. For example, the visually enhanced display can include, but is not limited to, sharpening, contrast adjustment, definition adjustment, brightness adjustment, and the like. For example, after determining the target sub-region, the electronic device can magnify and display the target sub-region. After determining the target sub-region, the electronic device can change the background color of the target sub-region to achieve the effect of visually enhanced display.

[0083] In the embodiments of the present application, the electronic device can send the picture rendering data of the current picture to other electronic devices in real time, so that the other electronic devices can highlight the target sub-region in the corresponding picture in real time.

[0084] In the embodiments of the present application, the target sub-region in the display area is highlighted in response to the highlight gesture of the user for the display area, and the gesture trajectory of the highlight gesture indicates the target sub-region. In this way, compared with the related art solution of opening a computer and adjusting a display picture to magnify a region, the number of steps of operating the computer is reduced, and the highlight of the region is performed through only one gesture, thereby shortening the reaction time of the highlight of the region and quickly and timely highlighting the region to be highlighted.

[0085] Referring to FIG. 2, an optional flowchart of a display method provided by the embodiments of the present application is shown, and S101 of FIG. 1 can also be implemented by S201 to S202, which will be described in combination with the steps:

[0086] S201, display a picture according to the collected video data, wherein the picture includes the display area.

[0087] In the embodiments of the present application, the electronic device collects video data in a predetermined region and plays the video data to display a corresponding picture. The picture played by the electronic device includes the display area, that is, the display content in the display area belongs to the predetermined region.

[0088] The area of the picture played by the electronic device is greater than or equal to the area of the display region in the picture, and the area of the target sub-region in the picture is greater than or equal to the area of the display region in the picture.

[0089] For example, as shown in FIG. 3, a user displays a presentation 11 in a desktop region. A camera 12 of an electronic device collects video data of the desktop region and plays the collected video data to display a corresponding picture. The picture 13 is a picture of the desktop region, and the picture 13 includes a display region corresponding to the presentation.

[0090] For example, as shown in FIG. 4, a user explains display content in a display board 14 in a region corresponding to the display board. A camera 12 of an electronic device configured to collect video data in the region corresponding to the display board 14 and play the collected video data to display a corresponding picture. The picture played by the electronic device includes the user, the display board 14, and the display content.

[0091] S202, in response to the highlighting gesture of the user for the display region, highlighting a target sub-region in the display region.

[0092] In the embodiments of the present application, in the process of playing the picture corresponding to the video data by the electronic device, the user shows a non-contact or contact highlighting gesture for the display region of the electronic device. The electronic device acquires gesture video data corresponding to the highlighting gesture, analyzes and determines a target sub-region indicated by the highlighting gesture according to the trajectory of the gesture in the gesture video data, and highlights the target sub-region.

[0093] In the embodiments of the present application, the electronic device can also acquire gesture video data of a highlighting gesture of the user for a key content in a predetermined region, analyze and determine a target sub-region corresponding to the key content in the display region of the picture of the electronic device according to the trajectory of the gesture in the gesture video data, and then highlight the target sub-region.

[0094] For example, as shown in FIG. 5, the user shows a highlighting gesture for the display picture 13, the electronic device acquires gesture video data corresponding to the highlighting gesture, analyzes and determines a target sub-region indicated by the highlighting gesture according to the gesture video data, and displays the target sub-region in the current picture 13.

[0095] For example, as shown in FIG. 4, the user shows a highlighting gesture for the display board 14, the electronic device acquires gesture video data corresponding to the highlighting gesture, analyzes and determines a target sub-region indicated by the highlighting gesture according to the gesture video data, and displays the target sub-region in the picture of the display board.

[0096] In the embodiment of the present application, a video data display picture is collected, wherein the picture includes the display area. In response to the user's highlight gesture for the display area, a target sub-area in the display area is highlighted. In this way, compared with the related art solution of opening a computer and adjusting a display picture to enlarge an area by a user, the steps of operating the computer by the user are reduced, and the target sub-area can be highlighted only by the user's gesture for the target sub-area in the display picture, thereby shortening the reaction time of area highlighting and quickly and timely highlighting the area to be highlighted.

[0097] Referring to FIG. 6, an optional flowchart of a display method provided by the embodiment of the present application is shown, and S202 shown in FIG. 2 can also be implemented by S301, which will be described in combination with the steps.

[0098] S301, in response to the user's highlight gesture for the display area in the picture, highlighting a target sub-area in the display area.

[0099] In the embodiment of the present application, the electronic device collects video data in a predetermined area to display a corresponding picture. When the user needs to highlight the key content in the predetermined area, the user can show a highlight gesture for the key content in the predetermined area. The electronic device collects gesture video data of the user's highlight gesture, determines the target sub-area corresponding to the key content in the display area of the picture based on the trajectory analysis of the gesture in the gesture video data, and highlights the target sub-area in the picture.

[0100] For example, in combination with FIG. 7, the user shows a highlight gesture for the presentation 11, the electronic device acquires gesture video data of the user's highlight gesture for the key content in the presentation 11, determines the target sub-area corresponding to the key content indicated by the highlight gesture in the picture 13 based on the analysis of the gesture video data, and enlarges and displays the target sub-area in the picture 13.

[0101] For example, in combination with FIG. 4, the user shows a highlight gesture for the display board 14, the electronic device acquires gesture video data of the user's highlight gesture for the key content in the display board 14, determines the target sub-area corresponding to the key content indicated by the highlight gesture in the picture based on the analysis of the gesture video data, and enlarges and displays the target sub-area in the picture.

[0102] In this way, compared with the solution in the prior art that a user opens a computer and adjusts a display screen to enlarge a region, the number of steps of operating the computer by the user is reduced, the user only needs to show a gesture for an entity region corresponding to a display region to highlight a target sub-region, and thus the reaction time of region highlighting is shortened, and the region that needs to be highlighted can be highlighted quickly and timely.

[0103] Please refer to FIG. 8, which is an optional flowchart of a display method provided in the embodiment of the present application. S101 shown in FIG. 1 can also be implemented by S401 to S402, which will be described in combination with the steps.

[0104] S401, in response to the highlighting gesture of the user for the display region, determining the target sub-region indicated by the gesture trajectory of the highlighting gesture, wherein the region range of the target sub-region matches the region range indicated by the gesture trajectory.

[0105] In the embodiment of the present application, when a user needs to highlight important content in a display region, the user can show a highlighting gesture with a trajectory defining function for the important content in the display region. An electronic device acquires gesture video data including the highlighting gesture of the user, and analyzes the gesture trajectory in the gesture video data to determine a region range (target sub-region) in the display region that matches the region range of the gesture trajectory.

[0106] In the embodiment of the present application, when the highlighting gesture is a highlighting stroke gesture (arc trajectory gesture, V-shaped trajectory gesture, or rectangular trajectory gesture), the electronic device can determine the region circled by the gesture as the target sub-region. When the highlighting gesture is a line drawing gesture, the electronic device can determine the region corresponding to the line drawing trajectory of the gesture as the target sub-region. When the highlighting gesture is a double-click gesture (display board), the electronic device can determine the region corresponding to the double-click gesture as the target sub-region. When the highlighting gesture is a double-click gesture (display board), the electronic device can determine the region corresponding to the double-click gesture as the target sub-region.

[0107] In the embodiment of the present application, the electronic device can analyze the gesture trajectory in the gesture video data based on a Hidden Markov Model (HMM) to determine the target sub-region whose region range matches the region range of the gesture trajectory. In other embodiments, the gesture video data can be analyzed by other detection models, which are not limited in the embodiment of the present application.

[0108] S402, highlighting the target sub-region in the display region.

[0109] In the embodiment of the present application, the electronic device can perform magnification display and / or visual enhancement display on the target sub-region in the display region.

[0110] In the embodiment of the present application, in response to the highlight gesture of the user for the display area, a target sub-area indicated by the gesture track of the highlight gesture is determined. The target sub-area in the display area is highlighted. In this way, compared with the solution in the related art that the user opens the computer and adjusts the display screen to enlarge the area, the steps of operating the computer are reduced, and the target sub-area is indicated by the gesture track to highlight only, the reaction time of the area highlighting is shortened, and the area that needs to be highlighted can be highlighted quickly and timely.

[0111] Please refer to FIG. 9, which is an optional flowchart of the display method provided by the embodiment of the present application. S401 shown in FIG. 8 can also be implemented by S501, which will be described in combination with the steps.

[0112] S501, in response to the arc motion gesture of the user for the display area, a target sub-area indicated by the arc gesture track of the arc motion gesture is determined, wherein the area range of the target sub-area matches the area range circled by the arc gesture track.

[0113] In the embodiment of the present application, when the user needs to highlight the important content in the display area, at least one arc motion gesture can be shown for the important content in the display area. Each arc motion gesture corresponds to an important content. The electronic device obtains gesture video data including at least one arc motion gesture of the user, analyzes and determines the gesture track of each arc motion gesture in the gesture video data, and the area circled by the gesture track of each arc motion gesture corresponds to a target sub-area in the display area. The area range of the target sub-area matches the area range circled by the corresponding arc gesture track.

[0114] In the embodiment of the present application, the user can show at least one arc motion gesture in turn, and the electronic device determines at least one corresponding target sub-area in the display area in turn according to the at least one arc motion gesture shown in turn. The at least one target sub-area determined in turn is highlighted.

[0115] For example, in combination with FIG. 10, when the user needs to highlight the important content in the display area 200 of the picture 100, one arc motion gesture can be shown for the important content in the display area 200. The electronic device obtains gesture video data including the arc motion gesture, analyzes and determines the target sub-area 300 according to the arc track of the arc motion gesture in the gesture video data. The target sub-area 300 is enlarged and displayed.

[0116] For example, in combination with FIG. 11, when a user needs to highlight important content in the picture 13, an arc motion gesture can be shown for the important content in the picture 13. The electronic device acquires gesture video data including the arc motion gesture, determines the target sub-region 300 according to the arc trajectory analysis of the arc motion gesture in the gesture video data, and displays the target sub-region 300 in the picture 13 in an enlarged manner.

[0117] For example, in combination with FIG. 7, when a user needs to highlight important content in the presentation 11 displayed in the picture 13, an arc motion gesture can be shown for the important content in the presentation 11. The electronic device acquires gesture video data including the arc motion gesture, determines the target sub-region according to the arc trajectory analysis of the arc motion gesture in the gesture video data, and displays the target sub-region in the picture 13 in an enlarged manner.

[0118] In this way, compared with the solution in the related art that a user opens a computer and adjusts a display picture to enlarge a region, the number of steps for the user to operate the computer is reduced, and the target sub-region is indicated only by the arc gesture trajectory of the arc motion gesture to highlight the target sub-region, the reaction time for region highlighting is shortened, and the region that needs to be highlighted can be highlighted quickly and timely.

The region range of the first sub-region matches the region range circled by the corresponding first arc motion gesture trajectory. The region range of the second sub-region matches the region range circled by the corresponding second arc motion gesture trajectory.

[0122] In the embodiments of the present application, the arc gesture trajectories of the at least two arc motion gestures respectively indicate N sub-regions. The electronic device respectively highlights the N sub-regions in different regions in the current screen. N is an integer greater than 2. There are various implementation manners for the electronic device to respectively highlight the first sub-region and the second sub-region in different regions in the current screen, for example, the first sub-region and the second sub-region can be highlighted in the current screen in a split-screen manner; for another example, the first sub-region and the second sub-region can be displayed in a picture-in-picture manner in the current screen; and the like.

[0123] For example, in combination with FIG. 13, the highlighting gesture exhibited by the user for the display region 200 includes two arc motion gestures, and the arc gesture trajectories of the two arc motion gestures respectively indicate the first sub-region 301 and the second sub-region 302. The electronic device can highlight the first sub-region 301 and the second sub-region 302 in a split-screen manner in the current screen 100.

The electronic device highlights the first sub-region 301 and the second sub-region 302 in a split-screen manner in the screen 13.

[0125] For example, in combination with FIG. 7, the user can exhibit a highlighting gesture including two arc motion gestures for the presentation 11, and the arc gesture trajectories of the two arc motion gestures can respectively indicate the first sub-region and the second sub-region. The electronic device can highlight the first sub-region and the second sub-region in a split-screen manner in the screen 13.

[0126] In the embodiments of the present application, the first sub-region and the second sub-region in the display region are highlighted, wherein the first sub-region and the second sub-region occupy different regions in the current screen, and the region range of the first sub-region and the region range of the second sub-region are determined based on the at least two arc motion gestures in sequence. In this way, the display of the first sub-region and the second sub-region in different regions in the current screen can form a contrast display effect, which facilitates the user to more clearly compare and explain the content in the first sub-region and the second sub-region, and provides a more clear and intuitive viewing experience for the viewer.

[0127] Please refer to FIG. 15, which is an optional flowchart of the display method provided by the embodiments of the present application. S101 shown in FIG. 1 can also be implemented by S601 to S602, which will be described in combination with the steps:

[0128] S601, detecting display content in a current picture to determine at least one candidate sub-region to be highlighted, wherein the candidate sub-region has a predetermined display identifier.

[0129] In an embodiment of the present application, the electronic device can pre-store a display content detection model, and the electronic device can also call a display content detection model at a cloud or other device in communication connection therewith. After obtaining video data to display a current picture, the electronic device can use the display content detection model to identify a candidate sub-region having a predetermined display identifier for the current picture.

[0130] In an embodiment of the present application, the predetermined display identifier can be a predetermined background color or a predetermined background pattern in the candidate sub-region. The predetermined display identifier can also be a predetermined font format or a predetermined font color corresponding to text information in the candidate sub-region. The predetermined display identifier can also be a predetermined format frame corresponding to the candidate sub-region.

[0131] In an embodiment of the present application, the interest point detection model can accurately identify the candidate sub-region of the current picture, without the need for manual identification by the user, and can effectively improve the efficiency of highlighting multiple key contents.

[0132] In some embodiments, the display content detection model uses at least one of the following algorithms: a target detection algorithm, a saliency detection algorithm.

[0133] The target detection algorithm can determine a region from a display picture. Common target detection algorithms include R-CNN (Region with Convolutional Neural Networks), SPP-Net (Spatial Pyramid Pooling Networks), Fast R-CNN (Fast Regions with Convolutional Neural Networks), R-FCN (Region-based fully convolutional network), OverFeat network, YOLOv1 (You Only Look Once v1) network, YOLOv3 (You Only Look Once v3) network, SSD (Single Shot Detection), RetinaNet (Retina network), and the like. The electronic device can directly use the above target detection algorithms as the algorithm of the display content detection model. In order to improve the recognition accuracy of the interest point detection model and meet the user demand, the above target detection algorithms can also be pre-trained by using a sample video of a region with a predetermined display identifier, and the pre-trained target detection algorithm is used as the algorithm of the display picture detection model.

[0134] The saliency detection algorithm can quickly detect a salient region in a display picture like a human eye. Common saliency detection algorithms include Itti algorithm, FT (Frequency-tuned) algorithm, SR (Spectral Residual) algorithm, HC (Histogram-based Contrast) algorithm, CA (Context-Aware) algorithm, and GR (Graph-Regularized) algorithm. Similarly, in order to improve the detection accuracy of the salient region and meet the user demand, the above saliency detection algorithms can be pre-trained by using a sample video of a region with a predetermined display identifier, and the pre-trained saliency detection algorithm is used as the algorithm of the display picture detection model.

[0135] S602, in response to a highlight gesture of the user for the candidate sub-region, highlighting the target sub-region in the display region; wherein the target sub-region belongs to at least one of the candidate sub-regions.

[0136] In the embodiments of the present application, when the user needs to highlight any candidate sub-region, the user can perform a highlighting gesture for the desired candidate sub-region. The electronic device obtains gesture video data including the highlighting gesture, analyzes the gesture video data to determine a target sub-region indicated by the gesture trajectory of the highlighting gesture in at least one candidate sub-region, and enlarges the target sub-region or displays a visual enhancement effect.

[0137] For example, in combination with FIG. 16, the electronic device can use the display content detection model to identify, for the current picture 100, a first candidate sub-region 401, a second candidate sub-region 402, and a third candidate sub-region 403 having a predetermined display identifier. The user can perform a highlighting gesture for the third candidate sub-region 403, and the electronic device can enlarge and display the third candidate sub-region 403 indicated by the highlighting gesture in the picture 100.

[0138] For example, in combination with FIG. 17, the electronic device can use the display content detection model to identify, for the picture 13, a first candidate sub-region 401 and a second candidate sub-region 402 having a predetermined display identifier. The user can perform a highlighting gesture for the first candidate sub-region 401, and the electronic device can enlarge and display the first candidate sub-region 401 indicated by the highlighting gesture in the picture 13.

[0139] For example, in combination with FIG. 7, the electronic device can use the display content detection model to identify, for the picture 13, a first candidate sub-region and a second candidate sub-region having a predetermined display identifier. The user can perform a highlighting gesture for the corresponding first candidate sub-region in the presentation 11, and the electronic device can enlarge and display the first candidate sub-region indicated by the highlighting gesture in the picture 13.

[0140] In the embodiments of the present application, the display content in the current picture is detected to determine at least one candidate sub-region to be highlighted, wherein the candidate sub-region has a predetermined display identifier. In response to a highlighting gesture of the user for the candidate sub-region, a target sub-region in the display region is highlighted, wherein the target sub-region belongs to the at least one candidate sub-region. In this way, by intelligently detecting the candidate sub-region in advance, when one of the sub-regions needs to be enlarged and displayed, the user only needs to perform a highlighting gesture to achieve the effect of enlarging and displaying the target sub-region, without the need for the user to use other components of the computer to achieve the enlargement, saving the process of enlargement and enabling the target sub-region to be enlarged quickly and timely.

[0141] Referring to FIG. 18, an optional flowchart of a display method according to an embodiment of the present application is provided, which will be described in combination with the steps:

[0142] S701, in response to a user's cancel gesture, cancel the highlighting effect for the target sub-region

[0143] In the embodiment of the present application, after the electronic device highlights the target sub-region, if the user needs to restore the initial state of the screen, the user can show a cancel gesture, the electronic device acquires gesture video data including the cancel gesture, and cancels the highlighting effect on the target sub-region according to the cancel gesture in the gesture video data.

[0144] In the embodiment of the present application, the cancel gesture can be any gesture different from the highlighting gesture. For example, the cancel gesture can be a gesture in which the user shows one finger, and the cancel gesture can also be a gesture in which the user shows other number of fingers. For example, the cancel gesture can be a static gesture, and the cancel gesture can also be a dynamic gesture.

[0145] For example, in combination with FIG. 19, after the electronic device highlights the target sub-region 300, the user can show a cancel gesture including two fingers, the electronic device acquires gesture video data including the cancel gesture, and cancels the highlighting effect on the target sub-region 300 according to the cancel gesture in the gesture video data.

[0146] For example, in combination with FIG. 20, after the electronic device highlights the target sub-region 300, the user can show a cancel gesture including two fingers, the electronic device acquires gesture video data including the cancel gesture, and cancels the highlighting effect on the target sub-region 300 according to the cancel gesture in the gesture video data.

[0147] For example, in combination with FIG. 7, after the electronic device highlights the target sub-region, the user can show a cancel gesture for the presentation 11, the electronic device acquires gesture video data including the cancel gesture, and cancels the highlighting effect on the target sub-region according to the cancel gesture in the gesture video data.

[0148] In this way, the user is provided with a scheme for canceling the highlighting effect, and the situation in which the electronic device cannot change the highlighting effect on the target sub-region is prevented.

[0149] Please refer to FIG. 21, which is an optional flowchart of a display method provided by the embodiment of the present application, which will be described in combination with steps:

[0150] S702, if an abnormal response of the highlighting gesture is detected, the target sub-region in the display region is highlighted in response to a preset static gesture of the user for the display region, wherein the area range of the target sub-region is determined based on the position information of the preset static gesture in the screen.

[0151] After the user performs the highlight gesture, the electronic device determines that the highlight gesture is abnormally responded if no highlight effect of the target sub-region is detected within a predetermined period. At this time, the user can perform a preset static gesture on important content in the display area, and the electronic device obtains gesture video data including the preset static gesture, and determines the target sub-region according to position information indicated by the preset static gesture in the gesture video data. The electronic device can display the determined target sub-region in an enlarged manner or with a visual enhancement effect.

[0152] In the embodiments of the present application, the preset static gesture can be non-contact or contact, for example, a single-click gesture or a double-click gesture.

[0153] In the embodiments of the present application, the electronic device can also highlight the target sub-region corresponding to the interaction position in the picture based on the distance between the interaction position of the preset static gesture and the boundary of the picture, and the distance between the interaction position and each boundary in the picture. If the distance between the interaction position and each boundary in the picture is greater than a preset distance, the target sub-region is highlighted in the picture with the interaction position as the center. If the distance between the interaction position and the first boundary in the picture is less than the preset distance, the target sub-region is highlighted with the second boundary as the starting point and the center of the picture as the ending point. The first boundary is the boundary closest to the click position, and the second boundary is the boundary with the shortest length among the first boundary and adjacent boundaries. For example, the preset static gesture can be a click gesture, and the interaction position can be a click position.

[0154] In the embodiments of the present application, when the highlight gesture is abnormally responded, a simpler preset static gesture can be performed to realize the highlight effect of the target region, thereby solving the problem that the target sub-region cannot be highlighted when the highlight gesture is abnormally responded.

[0155] Please refer to FIG. 22, which is an optional flowchart of a display method provided by the embodiments of the present application, which will be described in combination with steps:

[0156] S703, the highlighted target sub-region is displayed in a picture-in-picture form at a predetermined position in the current picture.

[0157] In the embodiments of the present application, after the electronic device highlights the target sub-region for a period of time, the highlighted target sub-region can be displayed in a picture-in-picture form at a predetermined position in the current picture. Alternatively, after the electronic device highlights the target sub-region, the electronic device displays the target sub-region in a picture-in-picture form at a predetermined position in the current picture in response to a user's dwell display gesture. Alternatively, after the electronic device highlights the target sub-region, the electronic device displays the target sub-region in a picture-in-picture form at a predetermined position in the current picture in response to a user's voice signal.

[0158] For example, in combination with FIG. 23, the electronic device displays the target sub-region 300 in a picture-in-picture form at the upper left corner of the current picture 100. In other embodiments, the electronic device can display the target sub-region 300 in a picture-in-picture form at other positions of the current picture 100.

[0159] For example, in combination with FIG. 24, the electronic device displays the target sub-region 300 in a picture-in-picture form at the upper left corner of the picture 13. In other embodiments, the electronic device can display the target sub-region 300 in a picture-in-picture form at other positions of the picture 13.

[0160] In the embodiments of the present application, the highlighted target sub-region is displayed in a picture-in-picture form at a predetermined position in the current picture. In this way, the viewer can compare the content in the target sub-region with the content displayed during the dwell period to more intuitively and clearly understand the display content that needs to be understood.

[0161] Please refer to FIG. 25, which is an optional flowchart of the display method provided in the embodiments of the present application, which will be described in combination with the steps:

[0162] S11. The user circles a region of the picture.

[0163] In the embodiments of the present application, during the user's explanation of the content in the picture, the user needs to display the key content in the picture in an enlarged form. The user can perform a circle gesture on the region in the picture that includes the key content.

[0164] S12. Whether the highlight gesture response is enabled.

[0165] In the embodiments of the present application, the electronic device detects whether the function of the highlight gesture response is enabled. If not, S13 is performed. If yes, S15 is performed.

[0166] S13. No need to identify the gesture, and the content in the region will not be partially enlarged.

[0167] In the embodiment of the present application, if the response function of the highlight gesture is not enabled, the key content in the picture will not be enlarged and displayed, and the current state of the picture is kept unchanged.

[0168] S14, the picture is kept in the current state.

[0169] S15, the circle gesture trajectory is recognized.

[0170] In the embodiment of the present application, if the response function of the highlight gesture is enabled, the electronic device recognizes the circle gesture trajectory, and determines the target sub-region including the key content in the picture based on the gesture trajectory. Note that only the gesture trajectory, the trajectory will not become the real picture. That is, the [trajectory line] in the schematic diagram will not appear on the screen.

[0171] S16, the content in the region corresponding to the gesture trajectory is enlarged and displayed on the full screen.

[0172] In the embodiment of the present application, the electronic device enlarges and displays the target sub-region on the full screen.

[0173] S17, the user shows a cancel gesture.

[0174] In the embodiment of the present application, when the user needs to restore the picture to the initial state, the cancel gesture can be shown to the picture.
