Detailed Description
Example embodiments will now be described more fully with reference to the accompanying drawings. However, the exemplary embodiments may be embodied in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
Furthermore, the drawings are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus a repetitive description thereof will be omitted. Some of the block diagrams shown in the figures are functional entities and do not necessarily correspond to physically or logically separate entities. These functional entities may be implemented in software or in one or more hardware modules or integrated circuits or in different networks and/or processor devices and/or microcontroller devices.
In the actual use process of the display terminal, the mode of controlling the display terminal through equipment such as a keyboard, a mouse or a remote controller in the related art is often influenced by space factors in many scenes, so that the problems of low control efficiency and low accuracy are caused. For example, in a conference, a computer and a projector may be far away, and since a presenter usually needs to speak depending on the screen of the projector, the display screen can be controlled only by the presenter moving repeatedly between the projector and the computer or by other people near the computer. However, the first method causes a problem of low control efficiency; the second approach suffers from inaccurate control due to the fact that the controller is not identical to the presenter.
In view of the foregoing drawbacks and disadvantages of the prior art, the present exemplary embodiment provides a new display control method, which may be applied to a mobile terminal configured with an image capturing module, such as a mobile phone, a tablet computer, etc., for controlling a display screen of a display terminal; the display terminal may include a display terminal provided with a display module, such as a computer and a television. Referring to fig. 1, the display control method described above may include the steps of:
s110, establishing communication connection with a display terminal;
s120, acquiring a display picture of the display terminal in real time through a camera module of the mobile terminal, and displaying a preview picture corresponding to the display picture;
and S130, in response to a first control operation on the preview screen, mapping the first control operation into a second control operation on the display terminal, and sending the second control operation to the display terminal to control the display screen.
In the display control method provided by the embodiment of the invention, the control of the display picture on the display terminal can be realized by operating the preview picture on the mobile terminal, a new display control mode is provided, the diversity of the display control mode is increased, and meanwhile, the display control of the display terminal is more convenient.
The steps of the display control method in the present exemplary embodiment will be described in more detail with reference to the accompanying drawings and examples.
Referring to fig. 1, in step S110, a communication connection with a display terminal is established.
In this example embodiment, the mobile terminal and the display terminal may be matched and connected in wifi, bluetooth, or the like, so that the mobile terminal and the display terminal are in the same local area network, so as to mutually transmit data, control information, and the like. The mobile terminal is provided with a camera module, and the camera module can be a camera module directly assembled on the mobile terminal or an independent camera module connected with the mobile terminal in a wired or wireless mode. The camera module can be used for shooting the current environment in real time and presenting a corresponding preview picture on a man-machine interaction interface of the mobile terminal. The display terminal refers to a display terminal capable of directly controlling a display picture. For example, the display screen on the computer can be controlled by the operation of the computer, so the computer is the display terminal of the disclosure.
In step S120, a display screen of the display terminal is obtained in real time through the camera module of the mobile terminal, and a preview screen corresponding to the display screen is displayed.
In this example embodiment, after the mobile terminal and the display terminal are connected in a matching manner, a control mode may be activated by a control instruction, and after the control mode is activated, a display screen on the display terminal is photographed in real time by the photographing module, and a preview screen corresponding to the display screen is presented on the mobile terminal. The control instruction may be a control instruction generated by a user performing an operation for activating the control mode on the mobile terminal or the display terminal.
In this example embodiment, the display screen of the display terminal obtained in real time by the camera module may be a display screen formed by directly shooting the display terminal through the camera module, or may be other devices for presenting the display screen of the display terminal by shooting the display module. For example, when the display terminal is a computer, the camera module can obtain a display picture of the computer by directly shooting a computer screen, and a preview picture corresponding to the display picture is presented on the mobile terminal; for another example, when the display terminal is a computer, a projector connected with the display terminal is provided for projecting the display screen of the display terminal, and at this time, the image projected by the projector can be shot by the camera module to form the display screen of the display terminal, so that a preview screen corresponding to the display screen is presented on the mobile terminal.
In this example embodiment, when the mobile terminal generates a preview screen corresponding to the display screen, referring to fig. 2, the method further includes the following steps S210 to S220:
step S210, comparing the current preview image with the display image to identify whether the preview image matches with the display image.
In this example embodiment, since the preview screen generated by the mobile terminal may initially have a problem that the image capturing module captures images of other display terminals that do not establish communication connection and does not match the display screen, it is necessary to obtain the current display screen of the display terminal while generating the preview screen, and determine whether the preview screen on the mobile terminal matches the display screen on the display terminal.
It should be noted that, in the case of poor network connection or delay in transmission, there is a possibility that the preview image and the display image are not matched, and at this time, the preview image and the display image corresponding to the image label or the time label may be compared by adding the image label or the time label to the display image, so as to avoid the problem of image mismatch caused by delay.
Specifically, when the preview screen includes a target area for presenting a display screen, referring to fig. 3, the comparing the current preview screen with the display screen to identify whether the preview screen matches with the display screen includes steps S310 to S340 as follows:
in step S310, a target area is identified in the preview screen, and a target screen included in the target area and the display screen are subjected to size conversion so that the target screen and the display screen have the same size.
In this exemplary embodiment, after the target area in which the display screen is presented is identified in the preview screen, for comparison, the target screen included in the target area and the display screen may be subjected to size conversion so that the sizes of the two are the same. For example, the size of both the target screen and the display screen may be converted to 1080 pixels.
Step S320, comparing the target frame with the display frame to calculate the similarity between the target frame and the display frame.
In this example embodiment, when comparing the target frame with the display frame, a pixel-by-pixel comparison manner may be adopted to calculate the similarity between the corresponding pixels of the target frame and the display frame, and finally, an average value of the similarity between all pixels is taken as the similarity between the target frame and the display frame; the similarity between the target picture and the display picture can be calculated by respectively extracting the characteristics of the target picture and the display picture, comparing the characteristics of the target picture and the display picture and further calculating the similarity of the characteristics of the target picture and the display picture; in addition, other ways for calculating the similarity of the image may be used to calculate the similarity of the target frame and the display frame, which is not particularly limited in the present disclosure.
In this other exemplary embodiment, since the image capturing module and the display screen may have a certain angle, the shape of the target screen may be different from the shape of the display screen, and at this time, the shape of the target screen may be corrected according to the correction algorithm, so that the shape of the target screen is consistent with the shape of the display screen, and then the comparison between the target screen and the display screen is performed.
In this other exemplary embodiment, after the target frame and the display frame are subjected to the size conversion, the target frame and the display frame may be further subjected to the gray scale processing, and further, the subsequent similarity calculation step is performed according to the gray scale value, so as to reduce the calculation amount when calculating the similarity.
And step S330, judging that the preview picture is matched with the display picture when the similarity is larger than or equal to a preset threshold value.
And step S340, judging that the preview picture is not matched with the display picture when the similarity is smaller than a preset threshold value.
In this example embodiment, when the calculated similarity is greater than or equal to a preset threshold, it is determined that the preview screen matches the display screen; otherwise, when the calculated similarity is smaller than a preset threshold value, judging that the preview picture is matched with the display picture. The preset threshold value may be set according to different resolutions of preview images acquired by different camera modules, or may be set according to a change frequency of a display image, which is not particularly limited in the present disclosure.
With continued reference to fig. 2, in step S220, upon identifying that the preview screen does not match the display screen, a prompt message is presented on the preview screen for adjusting the preview screen to match the display screen.
In this example embodiment, when it is identified that the preview screen does not match with the display screen, a prompt message may be generated and displayed on the preview screen to prompt the user that the current preview screen does not include a controllable display screen, and the user may adjust the image capturing module according to the prompt until the preview screen generated on the mobile terminal matches with the display screen.
In step S130, in response to a first control operation on the preview screen, the first control operation is mapped to a second control operation on the display terminal, and the second control operation is transmitted to the display terminal to control the display screen.
In this example embodiment, the control operation includes an operation position and an operation type, and referring to fig. 4, mapping the first control operation to a second control operation for the display terminal includes the following steps S410 to S430:
step S410, determining a second operation position of a second control operation for the display terminal in the display screen according to the first operation position of the first control operation.
In this example embodiment, when the preview screen includes a target area in which the display screen is presented, the determining a second operation position in the display screen for a second control operation of the display terminal based on the first operation position of the first control operation, as shown in fig. 5, includes the following steps S510 to S530:
step S510, identifying a target area in the preview screen, and acquiring a target pixel corresponding to the target area in the preview screen.
In this example embodiment, a target area including a display screen is identified in a preview screen, and a pixel area of the target area in the preview screen is determined. For example, the target area is in the upper left corner of the preview screen, and the size of the target area is a square area of 40 pixels by 40 pixels, and then the pixel area corresponding to the target area can be determined to be a square area with (1, 1), (1, 40), (40, 1), (40, 40) pixels as vertices in the preview screen.
Step S520, generating a pixel mapping relationship between the target area and the display screen based on the target pixel.
In this exemplary embodiment, after the target area is identified, the display screen is equally divided into a plurality of screen areas according to the number of pixels included in the target area in the lateral and longitudinal directions, and a one-to-one correspondence is generated according to the positions of the target pixels and the positions of the screen areas to form a pixel mapping relationship between the target pixels and the pixels included in the screen areas. For example, in the above embodiment, the target area is 40 pixels by 40 pixels in size, and 40 pixels are included in each of the horizontal direction and the vertical direction, so that the display screen can be equally divided into 40 parts in each of the horizontal direction and the vertical direction, forming 160 screen areas. And finally, determining the corresponding relation between each target pixel and each display area according to the position of each pixel in the target area and the positions of 160 picture areas, for example, the target pixel (40, 40) corresponds to the display area (40, 40) in the display picture, and further generating the pixel mapping relation between the target pixel and the pixels contained in the corresponding display area.
Furthermore, since a certain angle may exist between the image capturing module and the display screen, the shape of the target area may be different from the shape of the display screen, and at this time, the target area may be corrected according to the correction algorithm, and then the step of generating the pixel mapping relationship may be performed. For example, due to the problem of the shooting angle of the camera module, the shape of the target area may be trapezoidal, and the display screen may be rectangular. At this time, the target area of the trapezoid may be corrected to be rectangular by a correction algorithm so as to generate a mapping relationship between pixels.
In addition, the gesture information of the current mobile terminal can be obtained through sensors such as gyroscopes configured by the mobile terminal and displayed on a preview picture, and a user can adjust the current gesture of the mobile terminal according to the gesture information, so that the camera module can obtain a target area with the same shape as the display picture, and the accuracy of the pixel mapping relation is improved.
Step S530, mapping the first operation position of the first control operation to the second operation position in the display screen according to the pixel mapping relationship.
In the present exemplary embodiment, on the basis of determining the pixel mapping relationship, the first operation position of the first control operation in the preview screen may be mapped to the second operation position in the display screen, and the effect of controlling the second operation position by operating the first operation position is achieved.
In addition, the present disclosure may also achieve the purpose of mapping the first operation position to the second operation position by forming a mapping relationship between the target frame and the display frame in other manners. For example, the display screen is filled in the target area to form a mapping relation between the target area and each position coordinate in the display screen, and then the mapping method is realized.
Step S420, determining a second operation type of the second control operation according to a preset mapping rule and the first operation type of the first control operation.
In this example embodiment, the preset mapping rule includes a mapping table for describing a mapping relationship between the first operation type and the second operation type. For example, when the mobile terminal is a device such as a mobile phone or a tablet computer, the first control operation type may include operation types such as clicking, long pressing, dragging, and the like; when the display terminal is a computer, the second operation type may include a type of left click of a mouse, drag of a left click of a mouse, right click of a mouse, and the like. The mapping table may be set to describe a mapping relationship between the first operation type and the second operation type. For example, clicking on a cell phone may correspond to a left click operation of a mouse on a computer. Meanwhile, when the mobile terminal and the display terminal are different devices, different settings can be performed according to the mapping relation between specific devices and operation types. In addition, the preset mapping rule may be other tools for describing the mapping relationship between the first operation type and the second operation type, which is not particularly limited in the present disclosure.
Step S430, generating a second control operation for the display screen based on the second operation position and the second operation type.
In this example embodiment, when the second operation position and the second operation type are determined, the second control operation on the display screen may be generated according to the second operation position and the second operation type. For example, the current display frame is a video playing frame, and the user drags the progress bar in the display frame by dragging the progress bar in the preview frame, so as to control the display frame to display the video frame corresponding to the progress bar.
It should be noted that, in the present disclosure, there is no clear sequence between the step S410 and the step S420, and the two steps may be performed simultaneously, or the step S410 may be performed first, then the step S420 may be performed, or the step S420 may be performed first, and then the step S410 may be performed.
In this exemplary embodiment, the problem of the distance between the camera module and the display screen may cause a situation that the target screen in the preview screen is small and cannot be operated. In this case, when the preview screen matches the display screen, the method further includes: and in response to a third control operation on the preview screen, controlling the preview screen to zoom in and out for performing the first control operation based on the zoomed preview screen.
In this example embodiment, after the preview screen is matched with the display screen, the user may zoom in and out the preview screen through the third control operation, so that the user may perform the first control operation based on the zoomed preview screen, and further control the display screen. Through setting up the mode of zooming when preview picture and display screen match, can be convenient for the user more accurate carry out first control operation, avoid appearing the wrong scheduling problem of operation position to a certain extent.
In this example embodiment, the display control method further includes: and acquiring an execution result of the second control operation on the display terminal, and calling a corresponding target application program according to the execution result.
In this example embodiment, some commonly used auxiliary applications may be required in controlling the display device. Therefore, when the display screen in the display device is controlled according to the second control operation, some application programs may be triggered, and at this time, the corresponding application programs also need to be called at the mobile terminal. For example, when the second control operation triggers the input interface on the display screen, an input method program may be invoked in the mobile terminal to perform an input operation on the input interface.
In addition, in order to prevent the problem that the preview screen interferes with the target application program due to movement of the camera module of the mobile terminal during the process of calling the target application program, referring to fig. 6, the method further includes the following steps S610 to S620:
step S610, when the target application is invoked, the preview screen is frozen to the current frame.
And step S620, when the call to the target application program is finished, the preview screen is unfrozen.
In this example embodiment, when the mobile terminal invokes the target application, the preview screen of the mobile terminal 710 may be frozen to the current frame, at which time the user may operate the target application on the current frame. In this state, the display screen of the display terminal 720 can continue to be dynamically displayed, as shown with reference to fig. 7; or may be consistent with the screen of the mobile terminal 710, as shown in fig. 8; after the call to the target application program is finished, the preview screen of the mobile terminal can be thawed, so that the user can conveniently perform other control operations. When the mobile terminal is in a call state for the target application program, the problem of interference caused by continuous change of the preview picture can be avoided by freezing the preview picture of the mobile terminal in the current frame, and meanwhile, the problem of control interruption caused by mismatching of the preview picture and the display picture due to movement of the camera module of the mobile terminal when the target application program is operated can also be avoided.
Further, in the present exemplary embodiment, a display control method is provided, which may be applied to a display terminal, such as a computer, a television, or the like. Referring to fig. 10, the display control method includes the following steps S1010 to S1020:
step S1010, establishing communication connection with the mobile terminal to acquire a second control operation sent by the mobile terminal.
In this example embodiment, the second control operation is an operation for the display terminal mapped according to the first control operation on the preview screen of the mobile terminal. For example, when the display terminal is a computer, the first control operation may be converted into operations such as clicking a left mouse button, clicking a right mouse button, and the like for the computer.
Step S1020, executing the second control operation to control the display screen of the display terminal.
In this example embodiment, after receiving the second control operation sent by the mobile terminal, the second control operation may be performed to perform corresponding control on the display screen. For example, the operation of the second control operation is a click operation for (30, 60) pixel, and the corresponding click operation is performed on (30, 60) pixel of the display screen.
Furthermore, in an example embodiment, after said establishing a communication connection with the mobile terminal, the method further comprises: and acquiring a first control operation sent by the mobile terminal, mapping the first control operation into a second control operation aiming at the display terminal, and executing the second control operation.
In this example embodiment, the first control operation may be directly sent to the display terminal, and the display terminal maps the first control operation for the preview screen of the mobile terminal to the second control operation for the display terminal according to the established mapping relationship, and executes the second control operation to complete the control of the display screen.
In addition, when the mobile terminal invokes the target application program, the display screen of the corresponding display terminal may also display the state of the target application program. At this time, referring to fig. 11, the method further includes:
step S1110, sending an execution result of the second control operation to the mobile terminal, so that the mobile terminal responds to the execution result and invokes a corresponding target application program;
step S1120, synchronously displaying the display state of the target application program on the preview screen.
Specifically, when the mobile terminal calls the target application program according to the execution result sent by the display terminal, the target application program is displayed in the preview screen, and the display state of the display screen in the preview screen is changed, at this time, the display state of the target application program in the mobile terminal in the preview screen can be synchronized to the display terminal. For example, as shown in fig. 9, when the mobile terminal 710 invokes an input method to input in an input box, the display state of the input method in the preview screen may include the input pinyin "shaniang", the alternative words "pick up, imagine, musk, shoot, luxury", and the input words "based on" in the input box. At this time, this display state may be synchronized to the display terminal 720 so that the user can see the input process through the display screen. Furthermore, it is also possible to synchronize in the display terminal only the influence of the target application program on the display screen in the preview screen.
