Detailed Description
With the development of computer technology, the split screen display technology is gradually replacing the traditional screen projection display technology. When a computer is connected with a plurality of display devices, a presenter can operate on a main screen to select contents to be displayed which need to be displayed on an auxiliary display device by means of dividing a display area or selecting a file to be displayed. The computer may send the content to be displayed to the auxiliary display device for display for viewing by the viewer.
Compared with the screen projection display technology, the split screen display can select the image of a specific area to be displayed on the auxiliary display equipment. The split-screen display technology is more convenient for a presenter to edit and modify the content to be displayed, and has higher flexibility. Particularly, in the field of education, a teacher can display questions on the auxiliary display device through the split screen display technology, answers of the questions are displayed on the main display device, and teaching is facilitated.
However, the split screen display technology may acquire an image signal corresponding to the main screen in real time. When the presenter edits the content to be presented, the image signal corresponding to the main display area is also sent to other display equipment for displaying. For example, in the example question explanation process, the teacher's operation of labeling the question stem is synchronously displayed on the auxiliary display device, and the student may know the answer of the test question in advance after seeing the label. In addition, in other fields, if there are private or confidential documents in a computer, the operation of opening a folder by a presenter may inadvertently reveal such information.
In order to provide a display scheme that a presenter can freely control display contents based on the existing split screen display technology, the present application provides a split screen display method, device, terminal and storage medium, and the following will describe a preferred embodiment of the present application from the perspective of computer software.
Referring to fig. 1, fig. 1 is a flowchart of a method of a split-screen display method provided in an embodiment of the present application, including:
s101: the method comprises the steps of responding to an image display instruction, collecting a first image of a preset area in a display area of a first display device, and sending the first image to a second display device so as to display the first image in the display area of the second display device.
In this embodiment, the presenter may first divide the preset area on the display area of the first display device for displaying on the second display device. The first display device can be a main display device directly connected with the computer, and a presenter can see and operate the content displayed on the first display device; the second display device may be an auxiliary display device such as a projector or an electronic blackboard, and is used for displaying the content to be displayed to the viewer.
When the computer receives an image display instruction, a first image of a preset area can be collected and sent to the second display device, so that the second display device can display the first image. In this way, the computer may capture an image of a specific area in the display area of the first display device as the first image, and the second display device displays the first image when the first image is transmitted. In this way, the presenter can select any of the display areas of the first display device to be displayed on the second display device.
In some possible implementations, the computer may capture the first image of the preset area by way of a video memory copy. Specifically, since the display card is a device in charge of the computer processing the output video signal, the content displayed by the first display device is converted by the display card. The computer can obtain the image of the display area of the first display device at the current moment by reading the data in the memory of the display card. Then, the computer may acquire, as the first image, an image corresponding to the relative position from the image of the display area of the first display device according to the relative position of the preset area in the display area of the first display device. Therefore, the image displayed in real time in the display area of the first display device can be obtained in a video memory copying mode, and synchronous display of the first display device and the second display device is achieved.
S102: responding to a display maintaining instruction, copying the first image to obtain a second image, and periodically sending the second image to the second display device to display the second image in a display area of the second display device until the display maintaining instruction stops executing.
When the computer receives the instruction of maintaining the display, the computer may copy the first image at the current time as the second image and stop acquiring the first image. And then periodically sending the second image to the second display device so as to display the second image in the display area of the second display device until the maintaining display instruction stops executing. Specifically, when receiving the instruction to maintain the display, the computer may read a first image from the display memory as a second image and store the second image in the memory, then calculate a time interval for sending the second image to the second display device according to the refresh rate of the second display device, and finally send the second image to the second display device according to the time interval. In this manner, the computer may continue to send the second image to the second display device before the sustain display instruction stops executing, thereby ensuring that the second display device always displays the second image. Of course, in some other implementations, the computer may determine the transmission period of the second image in other ways. For example, the computer may send the second image to the second display device at regular intervals. The second display device can store the second image after receiving the second image sent by the computer and continuously display the second image before the next time interval until the maintaining and displaying instruction stops executing.
The embodiment provides a split-screen display method, which can switch display contents according to a received display instruction when split-screen display is performed. When an image display instruction is received, a first image of a preset area can be collected in a display area of first display equipment, and the first image is sent to second display equipment so as to be displayed in the display area of the second display equipment; when a display maintaining instruction is received, the first image may be copied to obtain a second image, and the second image is periodically sent to the second display device to be displayed in a display area of the second display device until the display maintaining instruction stops executing. In this way, the computer can send real-time images or pre-captured images to the second display device in response to different instructions sent by the presenter to switch between displaying in real-time and maintaining display. When the presenter needs to share the real-time screen, the presenter can send an image display instruction, at the moment, the contents displayed by the second display device and the first display device are synchronous, and the viewer can see the first image displayed on the first display device. When the presenter does not want the viewer to see the image on the first display area, a display maintaining instruction may be sent, at which time synchronization between the first display device and the second display device is cut off, and the viewer can only see the second image before receiving the instruction and does not see the operation of the presenter on the computer after receiving the instruction. Therefore, the presenter can freely select the presented content, and the method is suitable for more application scenes.
In some possible implementations, the presenter may also control the second display device to display other pre-stored pictures through the fixed display instruction. Specifically, when the computer receives a fixed display instruction, a pre-stored screen saver picture or other pictures may be acquired as a third image, and the third image is periodically sent to the second display device to be displayed in the display area of the second display device until the fixed display instruction stops executing. Therefore, when the presenter operates in response to the fixed display instruction, the second display device can be controlled to display the preset screen protection picture, and therefore the viewer is prevented from seeing the operation performed by the presenter.
In some possible implementations, the presenter may need to update the second image displayed by the second display device. At this point the presenter may send an update display instruction to the computer. And the computer responds to the display updating instruction, acquires an image of a preset area in the display area of the first display equipment at the current moment as a new first image, and copies the first image to obtain a new second image. And periodically sending the new second image to the display area of the second display device for continuous display. In this way, in response to the update display instruction, when the presenter needs to update the second image displayed in the display area of the second display device, the image of the preset area at the current moment can be collected and used as a new second image, and the update of the display content of the second display device is completed.
In some possible implementations, a computer may be connected to more than two display devices, each of which may be used to display different content. At this time, the computer may set a plurality of preset collection partitions on the first display device according to the instruction of the presenter, and then configure the corresponding relationship between the plurality of preset collection partitions and the plurality of second sub-display devices according to the setting of the presenter. When displaying, the computer may capture a plurality of first images of a plurality of preset capture zones from a display area of the first display device. And according to the corresponding relation between the preset acquisition subarea and the second sub display equipment, sending the plurality of first images to the second sub display equipment corresponding to the preset acquisition subarea where the first images are located. Therefore, the corresponding relation between the preset collection subarea and the second sub-display device is recorded, the collected first image can be sent to the sub-display device corresponding to the preset collection subarea to be displayed, the common display of a plurality of display devices is realized, and the method is suitable for application scenes such as a large screen spliced by a plurality of screens.
In order to facilitate understanding of the technical scheme of the present application, a description is provided below for a split-screen display method provided by the present application in conjunction with a specific teaching scene.
Referring to fig. 2, an application scenario of the split-screen display method includes a classroom 201, a plurality of desks and students 202, a lecture desk 203 equipped with a first display device, and a blackboard 205 equipped with a second display device. The first display device is connected to the computer device for displaying courseware for lecture on its display area 205. The courseware for teaching comprises an answer part A and a test question part B. When the teacher gives a lesson, a preset area 206 may be set in the display area 205 of the first display device 203. When the courseware is played, the computer can collect the first image of the preset area 206 and send the first image to the second display device 204, so that the second display device 204 can display the content in the preset area 206, and at the moment, the student can see the test question part B and cannot see the answer part a.
In the process of solving the test questions by the students, the teacher may mark the test question part B, but the marks are seen by the students, which may make the students know the answers in advance. In this case, the teacher may send a maintain display instruction to the computer. And the computer responds to the display maintaining instruction, copies the first image at the current moment to obtain a second image, and sends the second image according to the refresh rate of the second display device 204, so that the second display device 204 is controlled to display the test question part B before labeling. Therefore, when the teacher operates the content to be displayed, the student cannot see the operation of the teacher by maintaining the display instruction, and only can see the content to be displayed before the operation.
It should be specially noted that fig. 2 is only a preferred embodiment of a specific application scenario of the split-screen display method provided in the present application, and does not represent all technical solutions of the present application.
