Where the following description refers to the drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the illustrative examples below are not intended to represent all implementations consistent with this disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as recited in the appended claims.

In order to solve the existing problems, the present disclosure provides an image projection method 10. FIG. 1 is a schematic flowchart of an image projection method 10 according to an exemplary embodiment. For a mobile terminal such as a tablet computer, the image projection method 10 includes steps S11 to S14, and each step is described in detail below.

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

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

Since the size of the display screen of the mobile terminal is different from that of the screen projection device, the image displayed on the full screen of the mobile terminal needs to be enlarged and displayed when the full screen is displayed by the screen projection device. In some embodiments, the screen projection device may display an image in an enlarged manner based on the display size ratio of the mobile terminal and the screen projection device. For example, the vertical length of the display screen of the mobile terminal is 15cm and the horizontal length is 8cm, the vertical display size of the screen projection device is 90cm, and the horizontal display size is 160cm. The image is enlarged so that the image fills the screen in one direction. After acquiring the image, the screen projection device can also display the image on the full screen according to the relationship between the size of the image and the display size of the screen projection device.

In step S12, an image presentation instruction is received.

In the embodiment of the present disclosure, the user can change the display manner of the images displayed in the mobile terminal and the screen projection device as required. The user can control the terminal device, so that the mobile terminal receives the image display instruction, and can also execute the preset instruction by clicking. For example, the corresponding image display instructions can be generated through different gestures on the touch screen of the mobile terminal, for example, two fingers keep pressing and move toward or away from each other to realize the reduction or enlargement of the image, and the finger swipe to realize the movement of the image 2. Keep pressing with two fingers and realize relative circular motion with two fingers to rotate the image. There are various manipulation methods, which are not limited here.

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

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

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 correspondingly changes the display mode of the image.

In the embodiment of the present disclosure, 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 can achieve consistent synchronous adjustment of the image displayed by the screen projection device, which enriches the screen projection function and meets the needs of more users.

In some embodiments, after the mobile terminal establishes a connection with the screen-casting device, the screen-casting 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., you can send the current interface information to the screen-casting device, so that the screen-casting device can display the entire content of the interface information, that is, mirror screencasting is used for screencasting, and the screen-casting device completely displays the content displayed by the mobile terminal. Therefore, it can be conveniently used in the display area of the screen projection device without observing the screen of the mobile terminal, thereby avoiding the inconvenience caused by the user's repeated switching of sight lines. If the currently displayed content is the details of the image, for example, selecting an image in the album to display a single image, etc., step S11 may be executed to enable the screen projection device to display the image. The screen projection method performed in step S11 may be a DLNA (DIGITAL LIVING NETWORK ALLIANCE, Digital Living Network Alliance) mode. In step S11, the screen projection instruction sent may be a protocol between the mobile device and the screen projection device. Switch or expand to realize another screen projection method, which can display images in more variety, display richer effects, and meet more needs of users.

In one embodiment, the image presentation instruction includes an image manipulation instruction; step S13 may include: in response to the image manipulation instruction, changing the presentation manner of the image in at least one of the following ways: rotating the image, zooming 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 screen projection device also changes the display mode synchronously, and maintains the changed display mode with that displayed by the mobile terminal. The images are consistent and meet the different needs of users. The images described in the embodiments of the present disclosure are not only limited to images in static image formats, such as jpg, jpeg, png and other image formats, but also include images in dynamic formats, such as images in gif format, and may also include images in video format. Such as mp4, rmvb format and so on. The user's transformation method for displaying the image may be one of the above, or a combination of multiple types. For example, the image is enlarged and then moved, and rotated at a certain angle. Video editing may include the operation of editing 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 fast-rewind playback, and so on.

On the basis of the above-mentioned embodiments, in some embodiments, the screen projection device may perform corresponding transformations according to different transformation methods. Step S14 may include: if the transformation includes rotating the image, presenting the instruction to cause the screen projection device to rotate in the same rotation. Rotate the displayed image at an angle; if the transformation includes scaling the image, the display instruction causes the screen projection device to scale the displayed image at the same scaling ratio; if the transformation includes moving the image, the display instruction makes the screen projection device move according to the movement of the image on the mobile terminal The distance, based on the display size ratio of the screen projection device and the mobile terminal, moves the displayed image. In this embodiment, when performing the rotation transformation of the image, the rotation angle can be acquired in real time, and the screen projection device performs the rotation in real time based on the rotation angle to maintain the synchronous transformation. When scaling and transforming an image, the scaling ratio can be obtained in real time, so that the currently displayed image can be scaled with the same ratio in the screen projection device. When moving the image, it can be based on the display size ratio between the screen projection device and the mobile terminal. For example, the ratio between the magnification of the mobile terminal and the magnification of the screen projection device depends on the size of the original image when the display screen of the mobile terminal is full and when the screen is full. The ratio when the screen projection device is fully displayed. For example, the original image needs to be enlarged by 2 times when it is full on the mobile terminal, and the original image needs to be enlarged by 3 times when it is full on the screen projection device. Then the ratio between the mobile terminal and the screen projection device It is 2:3. At this time, the image is moved by 2 pixels on the mobile terminal, and 3 pixels on the screen projection device.

Through the above embodiment, the transformation performed by the user in the currently displayed image is synchronized in both the mobile terminal and the screen projection device, so that the image can be displayed and shared conveniently, and different display needs of the user can be met.

In other embodiments, the display manner of multiple images in the mobile terminal can be set or changed. As shown in FIG. 2 , the image display instruction includes a slideshow instruction; step S13 may include: step S131 , acquiring an image set corresponding to the image, wherein the image set includes a plurality of images to be displayed; step S132 , at a preset time, randomly Or display the images to be displayed in the image set in sequence. In this embodiment, there may be an image set composed of multiple images in the mobile terminal, for example, all photos, or an image folder set according to the user. The user can display the images of the image set in turn by way of a slideshow. The slideshow 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 user instructions. The playback order can be randomly generated, or it can be determined according to the properties of the images, such as the collection order, size order, etc., and displayed sequentially. After the user performs corresponding operations on the mobile terminal to display in a slideshow manner, the screen projection device also displays in a slideshow manner synchronously, and is synchronized with the images displayed in the mobile terminal. In some embodiments, when a slide show is performed on an image, various forms of switching effects can be used in the image switching composition, for example, the current displayed image fades out, the next displayed image fades in; the current displayed image flies out, The next show image flies in and so on. By increasing the switching effect of images during the slide show, the experience of the slide show is increased, and the display content is vivid and more enjoyable to watch.

In one embodiment, step S14 may include: sending the currently displayed image in the image set to the screen projection device in real time, and causing the screen projection device to simultaneously display the currently displayed image. During the slideshow, the mobile terminal can send the currently displayed image to the screen projection device in real time, so that the screen projection device can display the images synchronously, so that the screen projection device can display the images in the slideshow mode. It is also possible to send several images to the screen projection device in advance according to the playback sequence, so as to reduce the display delay between the mobile terminal and the screen projection device caused by real-time transmission.

In another embodiment, step S14 may include: sending the image set and playback information to the screen projection device, so that the to-be-displayed images in the display image set by the screen projection device are synchronized with the mobile terminal, wherein the playback information at least includes a preset time and playback information. order. In this embodiment, the image set to be played in the slideshow mode can be sent to the screen projection device, and at the same time, the preset time and playback order can also be sent to the screen projection device, and the screen projection device can display the images in the image set according to the playback order. A slideshow-style playback is performed, wherein the playback sequence may be randomly generated by the mobile terminal, or may be generated according to the attributes of the images. Since the preset time and the playback order are the same as the playback in the mobile terminal, synchronous playback of the two can be achieved.

During the slideshow, you can add some display effects to the displayed images. In some embodiments, step S13 may further include: determining a designated point of the currently displayed image; and taking the designated point as a base point, enlarging the currently displayed image. In this example, some effects are added to the currently displayed image during the slideshow-style image display process to make the slideshow more artistic. In this embodiment, the designated point may be a preset preset point, such as any point in the four corners of the image, or may be a randomly determined random point. Taking the designated point as the base point, the currently displayed image is enlarged, which can be a dynamic process of moving the designated point slowly to the center of the display area, thereby realizing the movement of the image and gradually enlarging the image.

In other embodiments, the designated point of the currently displayed image may 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 slideshow effect can further 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. If a person is identified in the image, the center pixel of the person can be used as the designated point, or It is determined that a key point such as the tip of the nose is used as the designated point. In this way, the playback of the slideshow can be made more visual. Moreover, in the screen projection device, it can be displayed synchronously with the mobile terminal. The mobile terminal can send the determined designated point to the screen projection device, and the projection device can perform the same magnification process according to the designated point to realize the synchronous display of the two. .
