When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.

To solve the problems, the disclosure provides an image projection method 10, fig. 1 is a schematic flow chart of an image projection method 10 according to an exemplary embodiment, the image projection method 10 may be applied to a mobile terminal such as a mobile phone, a tablet computer, etc., the image projection method 10 includes steps S11-S14, and the following details are given.

In step S11, a screen-throwing instruction and an image are sent to the screen-throwing device, so that the screen-throwing device displays the image.

In the embodiment of the disclosure, the screen projection device may be a device capable of displaying images in a large size, such as a television, a display or a projection device, and may establish near field connection with a mobile terminal, for example, may be connected through wifi or may be connected through bluetooth. After the connection is established, the mobile terminal can send an image needing to be projected to the projection equipment, and the projection equipment displays the image based on the projection instruction.

Since the display size of the mobile terminal is different from the display size of the screen-throwing device, an image displayed on the full screen of the mobile terminal needs to be enlarged and displayed when the full screen display is performed by the screen-throwing device. In some embodiments, the screen projection device may enlarge the image based on a display size ratio of the mobile terminal to the screen projection device. For example, the longitudinal length of the display screen of the mobile terminal is 15cm, the transverse length is 8cm, the longitudinal display size of the screen throwing device is 90cm, the transverse display size is 160cm, and the image is enlarged as magnification factor according to the minimum value in the size proportion of the two directions, so that the image can be ensured to be fully supported on the screen in one direction. The screen throwing device can also display the image in full screen according to the relation between the size of the image and the display size of the screen throwing device after the image is acquired.

In step S12, an image presentation instruction is received.

In the embodiment of the disclosure, a user can change the display modes of images displayed in the mobile terminal and the screen throwing equipment according to the needs. The user can control the terminal equipment to enable the mobile terminal to receive the image display instruction, and can execute a preset instruction by clicking. For example, corresponding image display instructions may be generated through different gestures on a touch screen of the mobile terminal, for example, two fingers keep pressing and move in opposite directions or in opposite directions to achieve reduction or amplification of an image, finger swipe achieves movement of the image, two fingers keep pressing and two fingers achieve relative circular motion to achieve rotation of the image, and various control modes are available and are not limited herein.

In step S13, in response to the image presentation instruction, the presentation style of the image is changed.

After receiving the image display instruction, the mobile terminal changes the display mode of the image according to the instruction. Changes to the image presentation may include zooming, selecting, moving, displaying multiple sheets in succession, adding special effects, and so forth.

In step S14, based on the image display instruction, a corresponding display instruction is sent to the screen projection device, so that the screen projection device transforms the display mode of the image correspondingly.

In the embodiment of the disclosure, after the user transforms the image displayed in the mobile terminal, the mobile terminal sends the corresponding display instruction to the screen projection device, so that the screen projection device can perform the same transformation on the displayed image, and the two images are synchronous. Therefore, the user can adjust the image displayed by the mobile terminal, so that the consistent synchronous adjustment of the image displayed by the screen throwing equipment can be realized, the screen throwing function is enriched, and the requirement of more users is met.

In some embodiments, after the mobile terminal and the screen throwing device are connected, the screen throwing mode can be switched automatically or manually according to the current application scene of the mobile terminal, if the current display content of the mobile terminal is interface information, such as displaying a mobile phone desktop, an album browsing interface and the like, the current interface information can be sent to the screen throwing device, so that the screen throwing device displays the whole content of the interface information, namely, the screen throwing is performed by adopting a mirror image screen throwing, and the screen throwing device completely displays the content displayed by the mobile terminal, thereby being convenient for users to use without observing the screen of the mobile terminal, and completing corresponding operation in the display area of the screen throwing device, and avoiding inconvenience caused by repeated conversion of vision by users. If the current display content is details of the image, for example, a certain image is selected in the album, and single-image display is performed, step S11 may be performed, so that the screen projection device displays the image. The screen-throwing mode performed in the step S11 may be a DLNA (DIGITAL LIVING NETWORK ALLIANCE) mode, and in the step S11, the transmitted screen-throwing instruction may be a protocol between the mobile device and the screen-throwing device is switched or expanded, so that another screen-throwing mode is implemented, more various display images can be displayed, more abundant effects can be displayed, and more demands of users can be implemented.

In an embodiment, the image presentation instructions comprise image operation instructions, and step S13 may comprise, in response to the image operation instructions, causing the presentation of the image to be transformed in at least one of a rotation image, a scaling image, a moving image, and a video editing. In this embodiment, the user operates the currently displayed image in the mobile terminal, changes the display mode of the currently displayed image, and synchronously, correspondingly changes the display mode in the screen-throwing device synchronously, so as to keep consistent with the transformed image displayed by the mobile terminal, and meet different requirements of the user. The images described in the embodiments of the present disclosure are not limited to the still picture format, such as jpg, jpeg, png, but also include the dynamic format, such as gif format, and may also include the video format, such as mp4, rmvb format, and so on. The user may change the image display mode by one of the above modes or may change the image display mode by a combination of a plurality of modes, for example, the image is enlarged and then moved and rotated by a certain angle. The video editing may include an operation of editing an image in a video format, and may also include an operation of adjusting a play mode of the video, such as a play speed change, a fast forward and fast backward play, and the like.

Based on the above embodiments, in some embodiments, the screen projection device may perform corresponding transformation according to different transformation modes, and step S14 may include, if the transformation includes rotating the image, displaying an instruction to make the screen projection device rotate the displayed image at the same rotation angle, if the transformation includes scaling the image, displaying an instruction to make the screen projection device scale the displayed image at the same scaling, and if the transformation includes moving the image, displaying an instruction to make the screen projection device move the displayed image according to a movement distance of the image at the mobile terminal based on a display size scale of the screen projection device and the mobile terminal. In this embodiment, when the rotation transformation of the image is performed, the rotation angle may be acquired in real time, and the rotation may be performed in real time in the screen projection device based on the rotation angle, so as to maintain the synchronous transformation. When the scaling transformation of the image is carried out, the scaling ratio can be obtained in real time, so that the currently displayed image is scaled in the same ratio in the screen projection equipment. When the image is moved, the display size ratio of the screen throwing device to the mobile terminal can be based on the ratio of the screen throwing device to the mobile terminal, for example, the ratio of the mobile terminal to the screen throwing device is enlarged, the image original image size is dependent on the ratio of the full screen display of the mobile terminal display screen to the full screen display of the screen throwing device, for example, the original image is fully supported on the mobile terminal and needs to be enlarged by 2 times, the original image is fully supported on the screen throwing device and needs to be enlarged by 3 times, the ratio of the original image to the screen throwing device is 2:3, at this time, 2 pixel points are moved on the mobile terminal, and 3 pixel points are required to be moved on the screen throwing device.

Through the embodiment, the conversion carried out by the user in the currently displayed image is synchronous between the mobile terminal and the screen projection equipment, so that the image can be conveniently displayed and shared, and different display requirements of the user are met.

In other embodiments, the manner in which the multiple images are presented in the mobile terminal may be set or changed. As shown in FIG. 2, the image display instruction includes a slide show instruction, and step S13 may include step S131 of acquiring an image set corresponding to the image, where the image set includes a plurality of images to be displayed, and step S132 of randomly or sequentially displaying the images to be displayed in the image set for a preset time. In this embodiment, there may be an image set composed of a plurality of images, for example, all photos, or an image folder set according to a user, etc. in the mobile terminal. The user can play and show the images of the image set in turn in a slide show mode. The slide show instruction may be generated based on the user clicking on the corresponding command key. The preset time is the time for displaying a single image and can be 5 seconds or set according to a user instruction. The playing order can be randomly generated, or can be determined according to the attribute of the image, such as the acquisition order, the size order and the like, and the images are displayed in sequence. After the user performs a corresponding operation on the mobile terminal to display in a slide manner, the screen-throwing device is also synchronously displayed in a slide manner and is synchronized with the images displayed in the mobile terminal. In some embodiments, in performing slide show on images, various forms of switching effects may be employed in performing the switching composition of the images, such as a current show image fades out, a next show image fades in, a current show image flies out, a next show image flies in, and so on. By increasing the image switching effect in the slide show process, the experience of the slide show is increased, so that the show content is vivid and has more ornamental value.

In one embodiment, step S14 may include sending the currently displayed image in the image set to the screen display device in real time, and causing the screen display device to synchronously display the currently displayed image. In the process of slide playing, the mobile terminal can send the currently displayed image to the screen throwing equipment in real time, so that the screen throwing equipment synchronously displays the images, and the screen throwing equipment realizes the images in a slide mode in a display image set. And a plurality of images can be sent to the screen throwing equipment in advance according to the playing sequence, so that display delay between the mobile terminal and the screen throwing equipment caused by real-time transmission is reduced.

In another embodiment, step S14 may include sending an image set and playing information to the screen capturing device, so that the image to be displayed in the image set displayed by the screen capturing device is synchronized with the mobile terminal, where the playing information includes at least a preset time and a playing sequence. In this embodiment, the image set to be played in the slide manner may be sent to the screen capturing device, and at the same time, the preset time and the playing sequence may also be sent to the screen capturing device, where the screen capturing device may perform slide playing on the images in the image set according to the playing sequence, where the playing sequence may be randomly generated by the mobile terminal, or may be generated according to the attribute of the images. Because the preset time and the play sequence are the same as those of the mobile terminal, synchronous play of the mobile terminal and the mobile terminal can be realized.

Some display effect can be added to the displayed image when the slide show is performed. In some embodiments, step S13 may further include determining a designated point of the currently displayed image, and enlarging the currently displayed image with the designated point as a base point. In this example, some effects are added to the currently displayed image during the display of the slide, making the slide more artistic. In this embodiment, the designated point may be a preset point, such as any point in four corners of the image, or may be a random point determined randomly. The current displayed image is amplified by taking the designated point as a base point, and the designated point can be slowly moved to the center of the display area, so that the movement of the image is realized, and the image is gradually amplified.

In other embodiments, the designated point of the currently displayed image may be determined by performing object recognition on the currently displayed image, taking a center point or a key point of the object as the designated point if the currently displayed image has the object, and determining the designated point according to a preset point or a random point if the currently displayed image does not have the object. In this embodiment, the specified point can be determined based on the specific content of the currently displayed image, so that the added slide effect more highlights the image content. The embodiment can determine whether a specific target exists in the currently displayed image, such as a person, a mountain peak and the like, through the target recognition model. If the target is identified, the center point of the target may be taken as a specified point, or any key point of the target may be taken as a specified point, for example, if a person is identified as being present in the image, the center pixel point of the person may be taken as a specified point, or a key point such as a determined nose tip may be taken as a specified point. By the method, the slide show can be played with more visual effect. In addition, in the screen projection equipment, synchronous display can be performed with the mobile terminal, the mobile terminal can send the determined designated point to the screen projection equipment, and the projection equipment can perform the same amplification processing according to the designated point, so that synchronous display of the two can be realized.

Based on the same inventive concept, the embodiment of the disclosure further provides an image screen projection method 20 correspondingly, as shown in fig. 3, the image screen projection method 20 can be applied to any one of the screen projection devices, so that the image can be synchronously displayed with the mobile terminal, the display mode change of the user on the mobile terminal can be correspondingly synchronously displayed, and the operation of the user on the screen projection device is met. The image screen projection method 20 comprises the steps of receiving a screen projection instruction and an image sent by a mobile terminal, displaying the image in response to the screen projection instruction, receiving a display instruction sent by the mobile terminal, generating the display instruction based on the image display instruction received by the mobile terminal, and converting the display mode of the image in response to the display instruction, so that the display mode corresponds to the display mode converted by the mobile terminal based on the image display instruction, wherein the step S21 is used for receiving the screen projection instruction and the image sent by the mobile terminal, and the step S23 is used for receiving the display instruction sent by the mobile terminal.

In one embodiment, step S22 may include magnifying the image based on the display size ratio of the mobile terminal to the screen-throwing device.
