Detailed ways

In order to make those skilled in the art better understand the solutions of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only It is a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

With the development of science and technology, the terminal can support users to use the terminal to watch images, so as to enrich the user's life. For example, when a user uses a terminal to view an image, the user can click an icon corresponding to the image. When the terminal detects that the user clicks on the icon of the image, the terminal may display the image. The images include, but are not limited to, pictures, images contained in videos, and the like.

FIG. 1 shows a schematic diagram of an application scenario of an image transmission method or an image transmission apparatus applied to an embodiment of the present application. As shown in FIG. 1 , when the terminal detects that the user clicks on the icon of the image, the terminal can read the image from the server, and transmit the read image to the display screen. The display screen may display an image based on the received image so that the user can view the image. However, since the image obtained by the terminal is not produced according to the size of the terminal display screen, the aspect ratio of the image is relatively fixed. However, in order to improve the user's hand feel and comfortable use experience, most of the terminal displays have a non-standard aspect ratio. The aspect ratio of the terminal display may be, for example, 19.5:9 or 20:9. Therefore, since the aspect ratio of the image is inconsistent with the aspect ratio of the display screen of the terminal, when the display screen of the terminal displays the image, a black border image will appear on the display screen of the terminal.

According to some embodiments, when the terminal transmits the acquired image to the display screen, the terminal transmits all data corresponding to the image line by line, and all data includes the image data displayed in the display area and the black border image data. Since the black-edge image will not affect the user's viewing of the image, the transmission of the black-edge image data will increase the image transmission time or increase the transmission rate, thereby reducing the image transmission efficiency.

The image transmission method provided by the embodiments of the present application will be described in detail below with reference to FIG. 2 to FIG. 12 . The execution subject of the embodiment shown in FIG. 2 to FIG. 12 may be, for example, a terminal.

Referring to FIG. 2 , a schematic flowchart of an image transmission method is provided in an embodiment of the present application. As shown in FIG. 2 , the method in this embodiment of the present application may include the following steps S101 to S103.

S101 , identifying the coordinates of two diagonal vertices of the image display area in the display screen.

According to some embodiments, the image display area refers to an area included in the display screen of the terminal where an image can be displayed. Since the size of the image and the size of the display screen are not exactly the same, when the display screen displays an image, there will be a black border image around the image displayed on the display screen. At this time, the image display area of the display screen of the terminal may be as shown in Figure 3.

It is easy to understand that, before receiving the image transmission instruction, the terminal can identify the coordinates of the two diagonal vertices of the image display area in the display screen. The terminal can also identify the coordinates of two diagonal vertices of the image display area in the display screen after receiving the image transmission instruction. The image transmission instructions include but are not limited to voice transmission instructions, text transmission instructions, and click transmission instructions, and so on. The image transmission instruction input by the user may be, for example, a voice transmission instruction, and the voice transmission instruction may be, for example, "play the second episode of the A TV series".

Optionally, after the terminal receives the image transmission instruction, the terminal identifies the coordinates of two diagonal vertices of the image display area in the display screen. For example, when the terminal receives the voice instruction, the terminal can use an image recognition algorithm to identify the image in the display screen, and determine the coordinates of the diagonal vertices of the display area of the image. The image recognition algorithm includes, but is not limited to, an image recognition algorithm based on a neural network, an image recognition algorithm based on a wavelet matrix, and the like. As shown in FIG. 4 , for example, the terminal may set vertex A of the display screen as the coordinate origin, and the coordinates of the diagonal corners of vertex A in the display screen may be (1080, 2340), for example. When the terminal adopts the image recognition algorithm based on the neural network to identify the display area of the image in the display screen, the terminal can determine the coordinates of the two diagonal vertices of the image display area. The two diagonal vertex coordinates may be (0, 80) and (1080, 2000), for example.

S102: Determine a first display resolution based on the coordinates of the two diagonal vertices and a preset shape.

According to some embodiments, the user may view the image using the terminal. When a user uses a terminal to view an image, the user can click an icon corresponding to the image on the display screen of the terminal, and the display interface of the terminal display screen at this time may be as shown in FIG. 5 . When the terminal detects that the user clicks on the icon corresponding to the image, the terminal can acquire the image. The terminal can acquire the image from the server, the terminal can also acquire the image from the storage of the terminal, and the terminal can also acquire the image from a movable device connected to the terminal. The removable devices include but are not limited to U disks, terminals, smart watches, and the like.

It is easy to understand that when the terminal uses an image recognition algorithm to identify the coordinates of two diagonal vertices of the image display area on the display screen, the terminal can determine the first display resolution based on the coordinates of the two diagonal vertices and the preset shape. The first display resolution refers to the resolution of the image in the image display area. The resolution is less than or equal to the resolution of the terminal display screen. The preset shapes include, but are not limited to, rectangles, squares, circles, triangles, and the like.

Optionally, the resolution of the display screen acquired by the terminal may be, for example, 2340*1080. When the terminal determines the first display resolution, the terminal may, for example, set vertex A of the display screen as the coordinate origin, and the coordinates of the diagonal corners of vertex A in the display screen may be (1080, 2340), for example. When the terminal adopts the image recognition algorithm based on the neural network to identify the display area of the image in the display screen, the terminal can determine the coordinates of the two diagonal vertices of the image display area. The two diagonal vertex coordinates may be (0, 80) and (1080, 2000), for example. The preset shape set by the terminal may be, for example, a rectangle. The area covered by the rectangle may be, for example, an image display area. Based on the preset shape and the two diagonal coordinates of the image display area, the first display resolution determined by the terminal may be, for example, 2000*1000.

S103: Transmit the image data carrying the coordinates of the two diagonal vertices to the display screen according to the first display resolution, where the display screen is configured to display in the image display area based on the coordinates of the two diagonal vertices the image data.

According to some embodiments, when the terminal acquires the first display resolution, the terminal may process image data to obtain image data to be transmitted. Wherein, the to-be-transmitted image data carries two diagonal vertex coordinates. When the terminal acquires the image data to be transmitted, the terminal can transmit the image data carrying the coordinates of the two diagonal vertices to the display screen according to the first display resolution, that is, the terminal can transmit the image data to be transmitted to the display screen. When the display screen receives the image data carrying the coordinates of the two diagonal vertices sent by the terminal, the display screen can supplement the black border image data corresponding to the image data based on the coordinates of the two diagonal vertices. When the display screen completes supplementing the black-edge image data, the display screen may display the received image data and the black-edge image data on the display screen, wherein the display screen may display the received image data in the image display area.

It is easy to understand that when the terminal transmits the image data carrying the coordinates of the two diagonal vertices to the display screen, the terminal can transmit the image data carrying the coordinates of the two diagonal vertices to the display screen within a preset time, and the terminal can also follow the preset time. Set the transmission speed to transmit the image data carrying the coordinates of the two diagonal vertices to the display screen.

Optionally, the first display resolution acquired by the terminal may be, for example, 2000*1000. When the terminal acquires the first display resolution, the terminal may acquire image data carrying two diagonal vertex coordinates (0, 80) and (1080, 2000) based on the first display resolution. When the terminal acquires the image data, the terminal may, for example, send the image data carrying two diagonal vertex coordinates (0, 80) and (1080, 2000) to the display screen within a preset time. When the display screen receives image data carrying two diagonal vertex coordinates (0, 80) and (1080, 2000), the display screen can display the received image data in the image display area, and display the received image data in the non-image display area of the display screen Displays image data with black borders.

An embodiment of the present application provides an image transmission method. By identifying the coordinates of two diagonal vertices of an image display area in a display screen and a first display resolution of the image display area, and according to the first display resolution, the two pairs of The image data of the corner vertex coordinates is transmitted to the display screen, so that the display screen can display the image data in the image display area based on the two diagonal vertex coordinates, so that the terminal can complete the image transmission process. Since the terminal does not need to transmit black border image data during the image transmission process, the data transmitted by the terminal can be reduced, and the power consumption of the terminal in image transmission can be reduced.

Referring to FIG. 6 , a schematic flowchart of an image transmission method is provided in an embodiment of the present application. As shown in FIG. 6 , the method in this embodiment of the present application may include the following steps S201 to S205.

S201 , identifying the coordinates of two diagonal vertices of the image display area in the display screen.

According to some embodiments, when the terminal receives an image transmission instruction input by the user, the terminal can use an image recognition algorithm to identify the area where the image is displayed on the display screen of the terminal, and determine two parts of the image display area on the display screen based on the coordinate system set by the terminal. Diagonal vertex coordinates. For example, the terminal may establish a coordinate system based on the size of the display screen of the terminal, and based on the identified image display area, the terminal may determine the coordinates of two diagonal vertices of the image display area. The terminal determines that the coordinates of two diagonal vertices of the image display area may be, for example, (0, 100) and (1080, 1600). The terminal may also determine the vertex coordinates of the four corners of the image display area based on the identified image display area.

S202: Determine a first display resolution based on the coordinates of the two diagonal vertices and a preset shape.

According to some embodiments, when the terminal acquires the coordinates of two diagonal vertices of the image display area, the terminal may acquire the preset shape. When the terminal acquires the preset shape, the terminal may determine the first display resolution based on the coordinates of the two diagonal vertices and the preset shape.

The specific process is as described above and will not be repeated here.

It is easy to understand that, when the terminal acquires the coordinates of two diagonal vertices of the image display area, the terminal can acquire and determine the first display resolution based on the shape of the image display area. For example, when the terminal acquires that the shape of the image display area is square, the terminal may determine the first display resolution based on the coordinates of two diagonal vertices and the shape of the square. The first display resolution determined by the terminal may be, for example, 1080*1500.

S203: Adjust the image data to a size corresponding to the first display resolution.

According to some embodiments, when the terminal acquires the first display resolution, the terminal may adjust the image data to a size corresponding to the first display resolution. The first display resolution determined by the terminal may be, for example, 1080*1500. For example, when the size of the image data obtained by the terminal is larger than the size corresponding to the first display resolution, the terminal may perform compression processing on the image data, and adjust the image data to the size corresponding to the first display resolution. For example, when the size of the image data acquired by the terminal is smaller than the size corresponding to the first display resolution, the terminal may perform enlargement processing on the image data, and adjust the image data to the size corresponding to the first display resolution.

S204: Divide the adjusted image data into multiple lines of image data.

According to some embodiments, when the terminal adjusts the image data to a size corresponding to the first display resolution, the terminal may divide the adjusted image data into multiple lines of image data. For example, the terminal may divide the image data into multiple lines of image data according to a preset number of lines. In this case, the multiple lines of image data may be as shown in FIG. 7 . For example, the terminal may divide the image data into multiple lines of image data according to the preset data size of each line.

It is easy to understand that the preset number of lines set by the terminal may be, for example, fifteen lines. After the terminal adjusts the image data to a size corresponding to the first display resolution, the terminal may divide the adjusted image data into fifteen lines of image data according to a preset fifteen lines. When the terminal divides the adjusted image data into multiple lines of image data, the terminal may perform labeling on the multiple lines of image data.

S205: Transmit the coordinates of the two diagonal vertices and the multi-line image data to the display screen.

According to some embodiments, when the terminal divides the adjusted image data into multiple lines of image data, the terminal may transmit the coordinates of the two diagonal vertices and the multiple lines of image data to the display screen. For example, before the terminal transmits the coordinates of two diagonal vertices and the multi-line image data to the display screen, the terminal may label the multi-line image data, and the terminal may transmit the multi-line image data to the display screen in ascending order of the labels. Screen. When the display screen receives the coordinates of the two diagonal vertices and the multi-line image data, the display screen can synthesize the multi-line image data according to the labels of the multi-line image data, and the display screen can display the image data based on the two diagonal vertex coordinates.

It is easy to understand that when the terminal divides the adjusted image data into multiple lines of image data, the terminal can encapsulate the coordinates of the two diagonal vertices and the multiple lines of image data into data packets, and transmit the data packets. to the display. When the display screen receives the data packet, the display screen can parse the data packet to obtain multi-line image data and two diagonal vertex coordinates. Based on the acquired multi-line image data and the coordinates of the two diagonal vertices, the display screen can combine the multi-line image data into image data and display the image data.

Optionally, the terminal may divide the adjusted image data into fifteen lines of image data according to the preset fifteen lines. When the coordinates of the two diagonal vertices are (0, 100) and (1080, 1600), the terminal Fifteen lines of image data and two diagonal vertex coordinates (0, 100) and (1080, 1600) can be packaged into a data packet and sent to the display screen. When the display screen receives the data packet, the display screen can parse the data packet, and obtain fifteen lines of image data and two diagonal vertex coordinates (0, 100) and (1080, 1600). The display screen can combine fifteen lines of data into image data and display the image data based on the coordinates of two diagonal vertices.

FIG. 8 shows a schematic diagram of an application scenario of an image transmission method according to an embodiment of the present application. As shown in FIG. 8 , when the sending terminal acquires image data carrying two diagonal coordinates, the sending terminal can use the server to carry the two diagonal coordinates. The image data is sent to the receiving terminal, or the sending terminal can directly send the image data carrying the two diagonal coordinates to the receiving terminal. Since the image data carrying the two diagonal coordinates sent by the sending terminal does not include black border image data outside the image display area, the transmitted image data can be reduced, the transmission time can be reduced, and the transmission efficiency can be improved.

According to some embodiments, please refer to FIG. 9 , which provides a schematic flowchart of an image transmission method according to an embodiment of the present application. As shown in FIG. 9 , the method in this embodiment of the present application may include the following steps S301 to S302. S301, obtaining the time when the image data is transmitted to the display screen according to the second display resolution of the display screen; S302, keeping the time unchanged, and sequentially converting the coordinates of the two diagonal vertices and the multi-line Image data is transmitted to the display screen.

It is easy to understand that the second display resolution may refer to the resolution of the display screen of the terminal, that is, the resolution corresponding to the image data in the image display area and the image data with black borders outside the image display area. When the terminal divides the adjusted image data into multiple lines of image data, the terminal can acquire the time when the image data is transmitted to the display screen according to the second display resolution of the display screen. The time obtained by the terminal may be, for example, 0.05 seconds. When the terminal obtains the time, the terminal can keep the time unchanged, and sequentially transmit the coordinates of the two diagonal vertices and the multi-line image data to the display screen. And multiple lines of image data are transmitted to the display. Since the terminal keeps the transmission time unchanged, but because the terminal does not need to transmit the black border image data outside the image display area to the display screen, the terminal can reduce the transmitted data and the transmission bandwidth, so the transmission power consumption of the terminal can be reduced. .

According to some embodiments, please refer to FIG. 10 , which provides a schematic flowchart of an image transmission method according to an embodiment of the present application. As shown in FIG. 10 , the method in this embodiment of the present application may include the following steps S401 to S402. S401, acquiring the speed at which the image data is transmitted to the display screen according to the second display resolution of the display screen; S402, keeping the speed unchanged, and sequentially converting the coordinates of the two diagonal vertices and the multi-line Image data is transmitted to the display screen.

It is easy to understand that the second display resolution may refer to the resolution of the display screen of the terminal, that is, the resolution corresponding to the image data in the image display area and the image data with black borders outside the image display area. When the terminal divides the adjusted image data into multiple lines of image data, the terminal can obtain the speed at which the image data is transmitted to the display screen according to the second display resolution of the display screen. The time acquired by the terminal may be, for example, 2000 Mbps per second. When the terminal obtains the speed, the terminal can keep the speed unchanged, and sequentially transmit the coordinates of the two diagonal vertices and the multi-line image data to the display screen, that is, the terminal can sequentially transfer the coordinates of the two diagonal vertices and the multi-line image data at a speed of 2000Mbps per second. Multiple lines of image data are transmitted to the display. Since the terminal keeps the transmission speed unchanged, but because the terminal does not need to transmit black border image data outside the image display area to the display screen, the terminal can reduce the transmission time, thereby improving the transmission efficiency of the terminal.

According to some embodiments, the terminal may transmit the image data carrying the coordinates of the two diagonal vertices to the display screen according to the first display resolution. When the display screen receives the image data of two diagonal vertex coordinates, the display screen can display the image data in the display area, and display the black border image data outside the image display area according to the second display resolution of the display screen. The second display resolution is the resolution of the display screen. When the display screen receives the image data sent by the terminal, the display screen can obtain the second display resolution of the display screen, and based on the second display resolution and the coordinates of the two diagonal vertices, the terminal can determine the black border image outside the display area data.

It is easy to understand that the second display resolution of the display screen may be, for example, 1080*1680. The image data acquired by the display screen may be, for example, fifteen lines of image data and two diagonal vertex coordinates (0, 80) and (1080, 1680). When the display screen acquires the coordinates of the two diagonal vertices, the display screen establishes a coordinate system based on the acquired second display resolution, and determines the area of the black-edge image based on the coordinates of the two diagonal vertices, and the display screen can be in the area of the black-edge image. The black border image data is not supplemented. When the black border image data is supplemented by the display screen, the display screen can display the image data and the black border image data.

According to some embodiments, please refer to FIG. 11 , which is a schematic flowchart of an image transmission method according to an embodiment of the present application. As shown in FIG. 11 , the method in this embodiment of the present application may include the following steps S501 to S502. S501, when the image data is key frame image data in the video data, transmit the image data carrying the coordinates of the two diagonal vertices to the display screen according to the first display resolution; S502, when the When the image data is non-key frame image data in the video data, the image data is transmitted to the display screen according to the first display resolution.

It is easy to understand that the key frame image data refers to the frame of image data in the video data where the key action in the movement or change of the character or object is located. The image data of the previous frame is the reference object, and the image data in which the coordinates of the two diagonal vertices corresponding to the display area of the key frame image data have changed. Since the coordinates of the two diagonal vertices of the image display area of the key frame are changed with respect to the coordinates of the two diagonal vertices of the image display area of the previous frame, the terminal may carry the coordinates of the two diagonal vertices according to the first display resolution. Image data is transmitted to the display screen.

Optionally, for example, the coordinates of the two diagonal vertices corresponding to the previous frame of image data obtained by the terminal are (0, 80) and (980, 1680), and the coordinates of the two diagonal vertices corresponding to the key frame image data are: (0, 80) and (1080, 1680), the terminal can transmit the image data carrying two diagonal vertex coordinates (0, 80) and (1080, 1680) to the display screen according to the first display resolution.

It is easy to understand that the non-key frame image data in the embodiment of the present application refers to that the image data of the previous frame of the key frame image data is used as a reference object, and the coordinates of the two diagonal vertices corresponding to the display area of the non-key frame image data have not changed. image data. Since the coordinates of the two diagonal vertices of the image display area of the non-key frame have not changed relative to the coordinates of the two diagonal vertices of the image display area of the previous frame, the terminal may not transmit the coordinates of the two diagonal vertices to the display screen, and the terminal may The non-keyframe image data is transmitted to the display screen at a first display resolution.

Optionally, for example, the coordinates of the two diagonal vertices corresponding to the previous frame of image data obtained by the terminal are (0, 80) and (980, 1680), and the coordinates of the two diagonal vertices corresponding to the non-key frame image data. When it is (0, 80) and (980, 1680), the terminal may transmit the non-key frame image data to the display screen according to the first display resolution.

The embodiment of the present application provides an image transmission method. By adjusting the image data, the adjusted image data can be divided into multiple lines of image data, and the coordinates of two diagonal vertices corresponding to the image display area and the multiple lines of image data can be divided. The data is transmitted to the display, which can display based on multiple lines of image data. Since the black border image data is not included in the multi-line image data, the terminal can reduce the data to be transmitted, thereby reducing the power consumption of the image transmission.
