Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
In order to solve the existing problems, the present disclosure provides an image projection method 10, and fig. 1 is a flowchart illustrating an image projection method 10 according to an exemplary embodiment, where the image projection method 10 may be applied to a mobile terminal such as a mobile phone, a tablet computer, and the like, and the image projection method 10 includes steps S11-S14, which are 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 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 a near field connection with the mobile terminal, for example, the near field connection may be through wifi or bluetooth. After the connection is established, the mobile terminal can send the image needing screen projection to the screen projection equipment, and the screen projection equipment displays the image based on the screen projection instruction.
Because the display screen size of the mobile terminal is different from the display size of the screen projection equipment, the image displayed on the full screen of the mobile terminal needs to be amplified and displayed when the screen projection equipment is used for displaying the full screen. In some embodiments, the screen projection device can display the image in an enlarged manner based on the 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 of the display screen is 8cm, the longitudinal display size of the screen projection equipment is 90cm, the transverse display size of the screen projection equipment is 160cm, and the image is magnified by taking the minimum value of the size proportion of the two directions as a magnification factor, so that the image can be ensured to fully support the screen in one direction. The screen projection equipment 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 equipment after the image is acquired.
In step S12, an image presentation instruction is received.
In the embodiment of the disclosure, the user can change the display modes of the images displayed in the mobile terminal and the screen projection device according to the needs. The user can control the terminal equipment, so that the mobile terminal receives the image display instruction, and can execute the preset instruction by clicking. For example, through a touch screen of the mobile terminal, through different gestures, corresponding image display instructions may be generated, for example, two fingers keep pressing and move in opposite directions or in opposite directions to reduce or enlarge an image, a finger strokes to move an image, two fingers keep pressing and two fingers realize relative motion in a surrounding manner to rotate an image, and the control manner may be various, and is not limited herein.
In step S13, the manner of presenting the image is changed in response to the image presentation instruction.
And after receiving the image display instruction, the mobile terminal changes the display mode of the image according to the instruction. The change of the image display mode can comprise zooming, selecting, moving, displaying a plurality of images continuously, adding special effects and the like.
In step S14, based on the image display command, a corresponding display command is sent to the screen projection device, so that the screen projection device transforms the display mode of the image accordingly.
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 transform the displayed image identically, and the two are synchronous. Therefore, the user can adjust the images displayed by the mobile terminal, the images displayed by the screen projection equipment can be synchronously adjusted, the screen projection function is enriched, and the requirements of more users are met.
In some embodiments, after the mobile terminal is connected with the screen projection device, the screen projection mode can be automatically or manually switched according to the current application scene of the mobile terminal, and if the current display content of the mobile terminal is interface information, such as a desktop of a mobile phone, an album browsing interface and the like, the current interface information can be sent to the screen projection device, so that the screen projection device displays all the content of the interface information, namely, the screen projection is performed by adopting mirror image screen projection, and the screen projection device completely displays the content displayed by the mobile terminal, so that the screen projection device can be conveniently used for completing corresponding operation in a display area of the screen projection device without observing the screen of the mobile terminal, and inconvenience caused by repeatedly switching the sight of a user is avoided. If the currently displayed content is details of an image, for example, a certain image is clicked in an album, and a single-view presentation is performed, step S11 may be executed to cause the screen projection apparatus to present an image. The screen projection mode performed in step S11 may be a DLNA (DIGITAL LIVING NETWORK ALLIANCE) mode, and the screen projection instruction sent in step S11 may be to switch or expand a protocol between the mobile device and the screen projection device, so as to implement another screen projection mode, which can display images more variously, display richer effects, and enable more requirements of the user.
In one embodiment, the image presentation instructions include image manipulation instructions; step S13 may include: responding to the image operation instruction, and enabling the display mode of the image to be transformed in at least one mode of the following modes: rotating an image, zooming an image, moving an image, video editing. In this embodiment, the user operates the currently displayed image in the mobile terminal to change the display mode of the currently displayed image, and the display mode is synchronously changed correspondingly in the screen projection device, so that the changed image displayed by the mobile terminal is kept consistent, and different requirements of the user are met. The images described in the embodiments of the present disclosure are not limited to images in still picture format, such as picture formats like jpg, jpeg, png, etc., but also include images in dynamic format, such as gif format images, and may also include images in video format, such as mp4, rmvb format, etc. The user may change the image presentation in one of the above-described manners, or may change the image presentation in a combination of a plurality of manners, for example, enlarging the image, moving the image, and rotating the image by a predetermined angle. The video editing may include operations of editing images in a video format, and may also include operations of adjusting a playing mode of the video, such as a change of a playing speed, fast forward and fast backward playing, and the like.
On the basis of the above embodiments, in some embodiments, the screen projection device may perform corresponding transformation according to different transformation manners, and step S14 may include: if the conversion comprises rotating the image, the display instruction enables the screen projection equipment to rotate the displayed image at the same rotation angle; if the conversion comprises zooming the image, the display instruction enables the screen projection equipment to zoom the displayed image at the same zooming ratio; if the conversion includes moving images, the display instruction enables the screen projection equipment to move the displayed images according to the moving distance of the images in the mobile terminal and based on the display size proportion of the screen projection equipment and the mobile terminal. In this embodiment, when performing rotation conversion of an image, a rotation angle may be acquired in real time, and the screen projection device performs rotation in real time based on the rotation angle, thereby maintaining synchronous conversion. When the image is zoomed, the zoom ratio can be obtained in real time, so that the currently displayed image is zoomed in the same ratio in the screen projection equipment. When moving the image, the ratio of the display size of the screen projection device to that of the mobile terminal, for example, the ratio of the mobile terminal to the screen projection device to be enlarged, depends on the ratio of the size of the original image to the size of the original image when the display screen of the mobile terminal is fully displayed and when the screen projection device is fully displayed, for example, the original image is fully extended on the mobile terminal and needs to be enlarged by 2 times, the original image is fully extended on the screen projection device and needs to be enlarged by 3 times, and then the ratio between the mobile terminal and the screen projection device is 2: and 3, moving 2 pixel points to the picture on the mobile terminal at the moment, and moving 3 pixel points on the screen projection equipment.
Through the embodiment, the conversion of the user in the currently displayed image is realized, and the mobile terminal and the screen projection equipment are synchronized, so that the image is conveniently displayed and shared, and different display requirements of the user are met.
In other embodiments, the display mode of the plurality of images in the mobile terminal may be set or changed. As shown in fig. 2, the image presentation instructions include slide show instructions; step S13 may include: step S131, obtaining an image set corresponding to the images, wherein the image set comprises a plurality of images to be displayed; step S132, randomly or sequentially displaying the images to be displayed in the image set in a preset time. In this embodiment, the mobile terminal may have an image set composed of a plurality of images, such as all photos, or an image folder set by a user. The user can take turns of the images of the image set in a slide show manner. The slide show instructions 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 sequence can be randomly generated, or can be determined according to the attributes of the images, such as the collection sequence, the size sequence, and the like, and can be displayed sequentially. After the user correspondingly operates the mobile terminal to display in a slide way, the screen projection equipment is synchronously displayed in a slide way and is synchronous with the image displayed in the mobile terminal. In some embodiments, when the images are subjected to a slide show, in the switching composition of the images, various forms of switching effects may be adopted, such as fading out the currently displayed image and fading in the next displayed image; the currently displayed image flies out, the next displayed image flies in, and so on. By increasing the switching effect of the images in the slide show process, the experience of slide show is increased, and the show content is vivid and has more ornamental value.
In one embodiment, step S14 may include: and sending the currently displayed images in the image set to the screen projection equipment in real time, and enabling the screen projection equipment to synchronously display the currently displayed images. In the process of playing the slide, the mobile terminal can send the currently displayed image to the screen projection equipment in real time, so that the screen projection equipment can synchronously display the image, and the screen projection equipment can display the image in a slide mode. And a plurality of images can be sent to the screen projection equipment in advance according to the playing sequence so as to reduce the display delay between the mobile terminal and the screen projection equipment caused by real-time transmission.
In another embodiment, step S14 may include: and sending the image set and the playing information to the screen projection equipment, so that the screen projection equipment displays the images to be displayed in the image set and synchronizes with the mobile terminal, wherein the playing information at least comprises preset time and a playing sequence. In this embodiment, an image set to be played in a slide mode may be sent to the screen projection device, and meanwhile, the preset time and the playing sequence may also be sent to the screen projection device, and the screen projection device may perform slide-type 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 generated according to attributes of the images. Because the preset time and the playing sequence are the same as the playing in the mobile terminal, the synchronous playing of the preset time and the playing sequence can be realized.
In the case of a slide show, some display effect may be added to the presented image. In some embodiments, step S13 may further include: determining a designated point of a currently displayed image; and magnifying the currently displayed image by taking the specified point as a base point. In this example, some effects are added to the currently displayed image during the slide show image display process, so that the slide show is more artistic. In this embodiment, the designated point may be a preset point set in advance, such as any one of the four corners of the image, or may be a random point determined randomly. The currently displayed image is enlarged with the designated point as a base point, which may be a dynamic process of slowly moving the designated point 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 presented image may be determined by: carrying out target identification on the currently displayed image; if the currently displayed image has a target, taking a central point or a key point of the target as a designated point; and if the currently displayed image has no target, determining a designated point according to a preset point or a random point. In this embodiment, the specified point can be determined based on the specific content of the currently displayed image, so that the increased slide effect more highlights the image content. The present embodiment may determine whether there is a specific object, such as a person, a mountain, etc., in the currently displayed image through the object recognition model. If the target is recognized, the center point of the target may be used as the designated point, or any key point of the target may be used as the designated point, for example, if a person is recognized to exist in the image, the center pixel point of the person may be used as the designated point, or one key point such as a determined tip of the nose may be used as the designated point. In this way, the playing of the slide show can be made more visually effective. And in the screen projection equipment, synchronous display can be carried out with the mobile terminal, the mobile terminal can send the determined specified point to the screen projection equipment, and the projection equipment can carry out the same amplification processing according to the specified point so as to realize synchronous display of the two.
Based on the same inventive concept, the embodiment of the present disclosure further provides an image screen projection method 20, as shown in fig. 3, the image screen projection method 20 may be applied to any one of the screen projection devices, so as to achieve synchronous image display with the mobile terminal, and enable a user to synchronously display changes of a display mode on the mobile terminal, thereby satisfying the operation of the user on the screen projection device. The image projection method 20 includes: step S21, receiving a screen projection instruction and an image sent by the mobile terminal; step S22, responding to the screen projection instruction, and displaying the image; step S23, receiving a display instruction sent by the mobile terminal, wherein the display instruction is generated based on the image display instruction received by the mobile terminal; and step S24, responding to the display instruction, and converting the display mode of the image to enable the display mode to correspond to the display mode converted by the mobile terminal based on the image display instruction.
