However, due to the small size of the display screen of the mobile terminal, browsing images has certain limitations, which makes it inconvenient to observe details. In addition, due to the limitation of the resolution of the mobile terminal display screen, the quality of high-definition images cannot be fully displayed. Moreover, in some cases, it is not convenient to show images to others through the display screen of the mobile terminal, and it is not convenient to share and display them.

[0048] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0049] In order to solve the existing problems, the present disclosure provides an image projection method 10. Figure 1 It is a flow chart of an image projection method 10 according to an exemplary embodiment. The image projection method 10 can be applied to mobile terminals such as mobile phones and tablet computers. The image projection method 10 includes steps S11 to S14. Each step is described in detail below.

[0050] In step S11, a screen projection instruction and an image are sent to a screen projection device so that the screen projection device displays the image.

[0051] In the disclosed embodiment, the screen projection device may be a device such as a television, a display or a projection device that can display images in a large size, and may establish a near-field connection with the mobile terminal, such as via wifi or Bluetooth. After the connection is established, the mobile terminal may send the image to be projected to the screen projection device, and the screen projection device displays the image based on the screen projection instruction.

[0052] Since the display screen size of the mobile terminal is different from the display size of the projection device, the image that is displayed full-screen on the mobile terminal needs to be enlarged and displayed when it is displayed full-screen through the projection device. In some embodiments, the projection device can enlarge and display the image based on the display size ratio of the mobile terminal and the projection device. For example, the vertical length of the mobile terminal display screen is 15cm and the horizontal length is 8cm, the vertical display size of the projection device is 90cm, and the horizontal display size is 160cm. The image is enlarged according to the minimum value of the size ratio in the two directions as the magnification factor, thereby ensuring that the image can fill the screen in one direction. After acquiring the image, the projection device can also display the image in full screen according to the relationship between the size of the image and the display size of the projection device.

[0053] In step S12, an image display instruction is received.

[0054] In the disclosed embodiment, the user can change the display mode of the image displayed in the mobile terminal and the projection device as needed. The user can control the terminal device so that the mobile terminal receives the image display instruction, or execute the preset instruction by clicking. For example, the corresponding image display instruction can be generated through different gestures through the touch screen of the mobile terminal, such as keeping two fingers pressed and moving toward or away from each other to achieve the reduction or enlargement of the image, swiping the finger to move the image, keeping two fingers pressed and the two fingers performing relative orbital motion to rotate the image. There can be many control methods, which are not limited here.

[0055] In step S13, in response to the image display instruction, the display mode of the image is changed.

[0056] After receiving the image display instruction, the mobile terminal changes the image display mode according to the instruction. The changes in the image display mode may include zooming, selecting, moving, continuously displaying multiple images, adding special effects, etc.

[0057] In step S14, based on the image display instruction, a corresponding display instruction is sent to the projection device, so that the projection device changes the image display method accordingly.

[0058] In the disclosed embodiment, after the user transforms the image displayed in the mobile terminal, the mobile terminal sends a 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 are synchronized. Therefore, the user can adjust the image displayed by the mobile terminal, and the image displayed by the screen projection device can be adjusted in a consistent and synchronous manner, which enriches the function of screen projection and meets the needs of more users.

[0059] In some embodiments, after the mobile terminal establishes a connection with the screen projection device, the screen projection mode can be switched automatically or manually according to the current application scenario of the mobile terminal. If the current display content of the mobile terminal is interface information, such as displaying the mobile phone desktop, album browsing interface, etc., the current interface information can be sent to the screen projection device, so that the screen projection device displays the entire content of the interface information, that is, the screen is projected using mirror projection, and the screen projection device fully displays the content displayed by the mobile terminal, so that it can be conveniently used without observing the screen of the mobile terminal. The corresponding operation can be completed in the display area of ​​the screen projection device, avoiding the inconvenience caused by the user repeatedly switching the line of sight. If the current display content is the details of the image, such as clicking on an image in the album to display a single image, etc., step S11 can be executed to make the screen projection device display the image. The screen projection method performed in step S11 may be a DLNA (DIGITAL LIVING NETWORK ALLIANCE) mode. In step S11, the screen projection instruction sent may be to switch or expand the protocol between the mobile device and the screen projection device, thereby realizing another screen projection method, which can display images more diversely, show richer effects, and meet more user needs.

[0060] In one embodiment, the image display instruction includes an image operation instruction; step S13 may include: in response to the image operation instruction, the display mode of the image is changed in at least one of the following ways: rotating the image, scaling the image, moving the image, and video editing. In this embodiment, the user operates the image currently displayed in the mobile terminal to change the display mode of the currently displayed image, and synchronously, the display mode in the projection device is also synchronously changed accordingly to keep consistent with the transformed image displayed by the mobile terminal to meet the different needs of the user. The image described in the embodiment of the present disclosure is not limited to images in static picture formats, such as jpg, jpeg, png and other picture formats, but also includes images in dynamic formats, such as gif format images, and may also include images in video formats, such as mp4, rmvb format, etc. The user's way of changing the image display may be one of the above, or a combination of multiple, for example, the image is enlarged and then moved, and rotated at a certain angle. Video editing may include the operation of clipping images in video format, and may also include the operation of adjusting the playback mode of the video, such as changing the playback speed, fast forward and rewind playback, etc.

[0061] On the basis of the above embodiments, in some embodiments, the projection device can perform corresponding transformations according to different transformation methods, and step S14 may include: if the transformation includes rotating the image, the display instruction causes the projection device to rotate the displayed image at the same rotation angle; if the transformation includes scaling the image, the display instruction causes the projection device to scale the displayed image at the same scaling ratio; if the transformation includes moving the image, the display instruction causes the projection device to move the displayed image based on the moving distance of the image in the mobile terminal and the display size ratio of the projection device and the mobile terminal. In this embodiment, when performing a rotation transformation of the image, the rotation angle can be obtained in real time, and the projection device can be rotated in real time based on the rotation angle to maintain synchronous transformation. When performing a scaling transformation of the image, the scaling ratio can be obtained in real time, so that the currently displayed image can be scaled at the same ratio in the projection device. When moving an image, it can be based on the display size ratio of the projection device and the mobile terminal. For example, the ratio of the mobile terminal magnification and the projection device magnification depends on the ratio of the original image size when the mobile terminal display is fully displayed and when the projection device is fully displayed. For example, the original image needs to be magnified 2 times to be fully displayed on the mobile terminal, and the original image needs to be magnified 3 times to be fully displayed on the projection device. Then the ratio on the mobile terminal and on the projection device is 2:3. At this time, if the image is moved by 2 pixels on the mobile terminal, it needs to be moved by 3 pixels on the projection device.

[0062] Through the above-mentioned embodiments, the changes made by the user in the currently displayed image can be synchronized in both the mobile terminal and the projection device, so that the image can be displayed and shared conveniently to meet the different display needs of the users.

[0063] In other embodiments, the display mode of multiple images in the mobile terminal can be set or changed. Figure 2As shown, the image display instruction includes a slide show instruction; step S13 may include: step S131, obtaining an image set corresponding to the image, wherein the image set includes multiple images to be displayed; step S132, randomly or sequentially displaying the images to be displayed in the image set at a preset time. In this embodiment, the mobile terminal may have an image set consisting of multiple images, such as all photos, or image folders set by the user. The user can play and display the images in the image set in turn in the form of a slide show. The slide show instruction can be generated based on the user clicking the corresponding command key. The preset time is the time for displaying a single image, which can be 5 seconds or set according to the user's instructions. The order of playback can be randomly generated or determined according to the attributes of the image, such as the acquisition order, size order, etc., for sequential display. After the user performs corresponding operations on the mobile terminal to display it in the form of a slide show, the projection device also synchronously displays it in the form of a slide show, and is synchronized with the image displayed in the mobile terminal. In some embodiments, when performing a slide show of images, in the switching of images, various switching effects may be used, such as fading out of the current display image and fading in of the next display image; flying out of the current display image and flying in of the next display image, etc. By adding the switching effect of the images during the slide show, the experience of the slide show is enhanced, making the display content vivid and more enjoyable.

[0064] In one embodiment, step S14 may include: sending the currently displayed image in the image set to the projection device in real time, and causing the projection device to synchronously display the currently displayed image. During the slide show, the mobile terminal may send the currently displayed image to the projection device in real time, causing the projection device to display synchronously, thereby enabling the projection device to display the images in the image set in a slide show manner. It is also possible to send several images to the projection device in advance according to the playback order to reduce the display delay between the mobile terminal and the projection device caused by real-time transmission.

[0065] In another embodiment, step S14 may include: sending an image set and playback information to a projection device, so that the projection device displays the images to be displayed in the image set synchronously with the mobile terminal, wherein the playback information at least includes a preset time and a playback order. In this embodiment, the image set to be played in a slideshow mode can be sent to the projection device, and at the same time, the preset time and playback order are also sent to the projection device. The projection device can play the images in the image set in a slideshow according to the playback order, wherein the playback order can be randomly generated by the mobile terminal or generated according to the attributes of the image. Since the preset time and playback order are the same as the playback in the mobile terminal, synchronous playback of the two can be achieved.

[0066] When playing a slide show, some display effects can be added to the displayed image. In some embodiments, step S13 may also include: determining a designated point of the currently displayed image; and enlarging the currently displayed image with the designated point as the base point. In this example, some effects are added to the currently displayed image during the slide show image display process to make the slide show more artistic. In this embodiment, the designated point can be a pre-set preset point, such as any point in the four corners of the image, or a randomly determined random point. Enlarging the currently displayed image with the designated point as the base point can be a dynamic process of slowly moving the designated point toward the center of the display area to achieve image movement and gradually enlarging the image.

[0067] In other embodiments, the designated point of the currently displayed image can be determined in the following manner: target recognition is performed on the currently displayed image; if there is a target in the currently displayed image, the center point or key point of the target is used as the designated point; if there is no target in the currently displayed image, the designated point is determined according to a preset point or a random point. In this embodiment, the designated point can be determined based on the specific content of the currently displayed image, so that the added slide effect can highlight the image content. In this embodiment, the target recognition model can be used to determine whether there is a specific target, such as a person, a mountain, etc., in the currently displayed image. If the target is identified, the center point of the target can be used as the designated point, or any key point of the target can be used as the designated point. For example, if a person is identified in the image, the central pixel point of the person can be used as the designated point, or a key point such as the tip of the nose can be used as the designated point. In this way, the slide show can be played with more visual effects. In addition, in the projection device, it can be displayed synchronously with the mobile terminal. The mobile terminal can send the determined designated point to the projection device, and the projection device can perform the same amplification processing according to the designated point to achieve synchronous display of the two.

[0068] Based on the same inventive concept, the embodiment of the present disclosure also provides an image projection method 20, such as Figure 3 As shown, the image projection method 20 can be applied to any of the above projection devices, so as to realize synchronous display of images with the mobile terminal, and can synchronously display the changes of the display mode on the mobile terminal correspondingly, so as to meet the user's operation on the image on the projection device. The image projection method 20 includes: step S21, receiving the projection instruction and image sent by the mobile terminal; step S22, displaying the image in response to the projection instruction; step S23, receiving the display instruction sent by the mobile terminal, wherein the display instruction is generated based on the image display instruction received by the mobile terminal; step S24, in response to the display instruction, changing the display mode of the image so that the display mode corresponds to the display mode changed by the mobile terminal based on the image display instruction.

[0069] In one embodiment, step S22 may include: based on the display size ratio of the mobile terminal and the projection device, enlarging and displaying the image.

[0070] In one embodiment, the display instruction includes an instruction for changing the display mode of the image in at least one of the following ways: rotating the image, scaling the image, and moving the image; step S24 may include: if the transformation includes rotating the image, rotating the displayed image at the same rotation angle; if the transformation includes scaling the image, scaling the displayed image at the same scaling ratio; if the transformation includes moving the image, moving the displayed image according to the moving distance of the image in the mobile terminal and based on the display size ratio of the mobile terminal and the projection device.

[0071] In one embodiment, step S24 may include: receiving the currently displayed image sent by the mobile terminal in real time, and synchronously displaying the currently displayed image.

[0072] In one embodiment, step S24 may include: receiving an image set and playback information sent by a mobile terminal, wherein the image set includes multiple images to be displayed, and the playback information includes at least a preset time and a playback order; and displaying the images to be displayed in the image set in the playback order at the preset time.
