[0047] In order to make the purpose, technical scheme and advantages of the present application clearer, the technical scheme in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application. The embodiments in the present application and the features in the embodiments can be combined with each other arbitrarily without conflict. The steps shown in the flowchart of the drawings can be executed in a computer system such as a group of computer executable instructions. Moreover, although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that here.

[0048] The technical scheme of the present application will be further described in detail below in combination with the drawings in the specification and specific embodiments.

[0049] Figure 1 a structural schematic diagram of a first device in the present application, asFigure 1 As shown, the first device 100 comprises an image acquisition apparatus 101, a first interface 102 and a second interface 103; wherein the image acquisition apparatus 101 is configured to acquire first image data; the first interface 102 is configured to be connected with the second device 200 and receive at least second image data sent by the second device 200, wherein the second image data comprises image data acquired by an image acquisition apparatus of the second device 200; and the second interface 103 is configured to be connected with the third device 300 and send at least data comprising the first image data and the second image data to the third device 300.

[0050] Here, the first interface 102 and the second interface 103 can both be a universal serial bus (USB, Universal Serial Bus) interface, preferably a USB-C interface. Of course, it can also be a display interface (DP, DisplayPort), a thunderbolt interface (Thunderbolt), or a high-definition multimedia interface (HDMI, High Definition Multimedia Interface).

[0051] Here, the types of the first device, the second device and the third device can be the same, such as all being displays.

[0052] Here, the types of the first device, the second device and the third device can also be different, such as the first device and the second device being displays and the third device being a device for generating or processing media data.

[0053] The electronic device provided in the present application not only can interact with a device having a function of generating or processing media data, but also can interact with a display, thereby not only expanding the functionality of the electronic device but also expanding the interaction range of the electronic device.

[0054] In the present application, the first device 100 can further comprise a processor 104 configured to merge the first image data and the second image data to obtain third image data; or the processor 104 can also be configured to combine the first image data and the second image data to obtain third image data.

[0055] Here, merging means fusing multiple independent images into one image, which cannot be directly split into the original independent images. For example, merging the independent first image data and the independent second image data into one third image data, the third image data being an independent image, which cannot be split into the independent first image data and the second image data.

[0056] Here, the combination is to fuse multiple independent images into an image group, each image still has relative independence, and the image group can be dispersed to restore the original independent image. For example, combining independent first image data and independent second image data into third image data, the third image data is an image data group, which can be split into independent first image data and second image data.

[0057] It should be noted that the processor 104 is different from the central processing unit (CPU) in the device with media data processing capability, and the difference can be embodied in that the processor 104 realizes image processing and coding and decoding through hardware, that is, the processor 104 is a processor with hardware image processing capability and hardware coding and decoding capability, while the CPU realizes image processing and coding and decoding through software.

[0058] In the present application, the first device 100 can specifically send the third image data to the third device 300 through the second interface 103.

[0059] Here, when the third device 300 is of the same type as the first device 100, the third device 300 can merge or combine the third image data with the image data collected by itself and send it to the next electronic device connected to the third device 300. Or, the third image data is directly forwarded to the next electronic device connected to the third device 300.

[0060] Here, when the third device 300 is of a different type from the first device 100, the third device 300 can send the third image data to a remote device connected to the third device, so that the third image data is displayed and output on the display screen of the remote device.

[0061] In the present application, the second image data sent by the second device 200 and received by the first device 100 through the first interface 102 can also include image data received by the second device 200 and sent by the fourth device 400, and the image data sent by the fourth device 400 includes at least image data collected by the image collection device of the fourth device 400.

[0062] Here, the second image data can be combined data of the image data collected by the image collecting device of the second device 200 and the image data sent by the fourth device 400 and received by the second device 200, or can be merged data of the image data collected by the image collecting device of the second device 200 and the image data sent by the fourth device 400 and received by the second device 200. When the second image data is the combined data of the image data collected by the image collecting device of the second device 200 and the image data sent by the fourth device 400 and received by the second device 200, the processor 104 of the first device 100 can be configured to merge the first image data, the image data collected by the image collecting device of the second device 200 and the image data collected by the image collecting device of the fourth device 400 to obtain the third image data. When the second image data is the merged data of the image data collected by the image collecting device of the second device 200 and the image data sent by the fourth device 400 and received by the second device 200, the processor 104 of the first device 100 can be configured to merge the first image data and the second image data to obtain the third image data.

[0063] In the present application, the image data sent by the fourth device 400 can further include image data sent by the fifth device 500 and received by the fourth device 400, and the image data sent by the fifth device 500 at least includes image data collected by the image collecting unit of the fifth device 500.

[0064] Here, the image data sent by the fourth device 400 can be combined data of the image data collected by the image collecting device of the fourth device 400 and the image data sent by the fifth device 500 and received by the fourth device 400; or can be merged data of the image data collected by the image collecting device of the fourth device 400 and the image data sent by the fifth device 500 and received by the fourth device 400. When the image data sent by the fourth device 400 is the combined data of the image data collected by the image collecting device of the fourth device 400 and the image data sent by the fifth device 500 and received by the fourth device 400, the processor 104 can be configured to merge the first image data, the image data collected by the image collecting device of the second device 200, the image data collected by the image collecting device of the fourth device 400 and the image data collected by the image collecting device of the fifth device 500 to obtain the third image data. When the image data sent by the fourth device 400 is the merged data of the image data collected by the image collecting device of the fourth device 400 and the image data sent by the fifth device 500 and received by the fourth device 400, the processor 104 can be configured to merge the first image data and the second image data to obtain the third image data. The second image data is the merged data of the image data collected by the image collecting device of the second device 200 and the image data sent by the fourth device; the image data sent by the fourth device is the merged data of the image data collected by the image collecting device of the fourth device 400 and the image data collected by the image collecting device of the fifth device 500.

[0065] In the present application, the first device 100 can further have an image output device 105, through which the first image data and / or the second image data can be output, or at least part of the first image data and / or the second image data can be output.

[0066] Here, the image output device 105 can be a display screen, the first device 100, the second device 200, the fourth device and the fifth device 500 can all be displays, and the first device 100, the second device 200, the fourth device and the fifth device 500 can have the same composition; the third device 300 can be a computer.

[0067] The display provided in the application not only has computing capability, but also has hardware processing data capability and hardware coding and decoding capability; in addition, through the device cascade mode (i.e. serial connection), the display can not only receive image data sent by the previous device (such as the second device), but also send image data collected by itself and image data sent by the previous device (such as the second device) to the next device (such as the third device), and can also receive data sent by the next device (such as the third device) and send data from the third device to the previous device (such as the second device). In this way, the third device can obtain camera image data of any device on the cascade link as needed, meeting the user's demand for images of different angles.

[0068] In the application, the first device can also have a plurality of first interfaces 102, the second device 200, the fourth device 400 and the fifth device 500 can be directly connected to the first device 100 through one first interface 102, the first device 100 can directly receive image data collected by the image collection device of the second device 200, the fourth device 400 and the fifth device 500, and can also send the image data collected by the image collection device 101 of the first device itself to the third device 300 after merging or combining the image data collected by the image collection device of the second device 200, the fourth device 400 and the fifth device 500.

[0069] In the application, the first device 100 further includes a selection device 106 for determining a target device in the candidate device in response to a selection instruction, the candidate device at least including the first device 100, the second device 200 and the fourth device 400 connected to the second device 200, and of course can also include the fifth device 500 and more cascade devices; wherein the second image data is combined data of image data collected by the image collection device of the second device 200 and image data sent by the fourth device 400, and the image data sent by the fourth device 400 at least includes image data collected by the image collection device of the fourth device 400; the second interface 103 is used for sending image data corresponding to the target device to the third device 300.

[0070] Here, the second interface 103 is further configured to receive the selection instruction sent by the third device 300, and the selection instruction carries at least a device identifier; the selection device 106 is further configured to send an image acquisition instruction to the second device 200 through the first interface 102 based on the device identifier, so that the second device 200 acquires an image through an image acquisition device of the second device 200 based on the device identifier carried in the image acquisition instruction; and / or, the selection device 106 is further configured to send the image acquisition instruction to the fourth device 400 through the second device 200 based on the device identifier, so that the fourth device 400 acquires an image through an image acquisition device of the fourth device 400 based on the device identifier carried in the image acquisition instruction. That is, the second device 200 can be used as a relay device between the first device 100 and the fourth device 400, and only forwards data.

[0071] Here, the selection device 106 can be a touch display screen, a physical button, a microphone, or the like input device. It can also be a software module implemented by part of the code integrated in the processor 104.

[0072] When the selection device 106 is an input device, the first device 100 can further receive a menu opening instruction implemented through the selection device 106, and through the menu opening instruction, a menu interface for device selection can be displayed on the display area of the first device 100. Then, the selection device 106 can further receive a selection instruction for each candidate device in the menu interface, and based on the device identifier carried in the selection instruction, the target device can be determined from the candidate devices.

[0073] For example, a user presses a physical button on the first device 100, and a menu interface for device selection can be popped up on the display area of the first device 100. The user can select a target device from a plurality of candidate devices displayed in the menu interface by pressing the physical button again.

[0074] Here, the first device 100 can receive the menu opening instruction from the selection device, and at the same time, receive the display data sent by the third device. At this time, the priority of the menu opening instruction can be higher than that of the display data. The first device 100 can display the target menu interface in the display area according to the priority of the menu opening instruction. Of course, the first device can also display the target menu interface and the display data in the display area at the same time. At this time, since the priority of the menu opening instruction is higher than that of the display data, at least part of the content of the display data can be blocked by the target menu interface.

[0075] In the present application, when the selection device is a software module of the processor, the first device can further include an input device through which a menu opening instruction can be received, based on which a menu interface for device selection can be displayed on the display area, and then the first device can further receive a selection operation for the multiple candidate devices in the menu interface, and by the processor identifying the device identifier carried in the selection operation, the target device can be determined.

[0076] Here, the first device can display a menu interface on the display screen through a screen menu type adjustment mode (OSD, on-screen display) to realize selection of the target device.

[0077] The first device provided in the present application has not only data selection capability but also enables the third device to access the camera image data of any device on the cascaded link according to user demand, thereby meeting different use demands of the user.

[0078] In the present application, the first device 100 can further send data including the first image data and the second image data to the third device 300 through the first data channel of the second interface 103, and receive the first display data sent by the third device 300 through the second data channel of the second interface 103, so that the first display data is displayed on the image output device 105.

[0079] Here, the first display data can be derived from the image data sent by the remote device received by the third device 300. Or it can also be the image data stored by the third device 300 itself.

[0080] In the present application, the first device 100 can further receive the second image data sent by the second device 200 through the first data channel of the first interface 102, and send second display data to the second device 200 through the second data channel of the first interface 102, so that the second display data is displayed on the image output device of the second device 200. Wherein, the first display data includes the second display data.

[0081] In one implementation, the second display data sent by the first device 100 to the second device 200 through the first interface 102 is the same as the first display data. For example, the second display data is all the data of the first display data.

[0082] In another implementation, the second display data sent by the first device 100 to the second device 200 through the first interface 102 is different from the first display data. For example, the second display data is part of the data in the first display data.

[0083] In the present application, the first display data can further include a plurality of sub-display data, each of which corresponds to an identifier, which is used to indicate the display order of each sub-display data on the corresponding device.

[0084] For example, the first display data includes three sub-display data, wherein the identifier corresponding to the first sub-display data is 1, indicating the first display; the identifier corresponding to the second sub-display data is 3, indicating the third display; and the identifier corresponding to the third sub-display data is 2, indicating the second display.

[0085] In the present application, the processor 104 can further determine a first sub-display data from the plurality of sub-display data based on the identifier, and display the first sub-display data through the image output device 105.

[0086] Here, the first device can be located at a first display position, and the identifier of the first sub-display data indicates the first display corresponding to the first device.

[0087] Then, the first device 100 can send the remaining sub-display data except the first sub-display data in the plurality of sub-display data to the second device 200 through the first interface 102, so that the second device 200 displays the corresponding second sub-display data in the remaining sub-display data through the image output device of the second device 200 based on the identifier; or, the first device 100 sends the remaining sub-display data to the fourth device 400 connected to the second device 200, so that the fourth device 400 displays the corresponding third sub-display data in the remaining sub-display data through the image output device of the fourth device 400 based on the identifier.

[0088] For example, the second device 200 is located at a second display position, and the fourth device 400 is located at a third display position, and the first display data includes two sub-display data, wherein the identifier corresponding to the first sub-display data is 1, indicating the first display and being displayed through the first device 100; and the identifier corresponding to the second sub-display data is 2, indicating the second display and being displayed through the second device 200. If the identifier corresponding to the second sub-display data is 3, indicating the third display, then the second device 200 forwards the data to the fourth device 400 for display through the fourth device 400.

[0089] Here, when data forwarding is performed through the second device 200, the data sent by the first device 100 to the second device 200 can carry an identifier, and the second device 200 can determine whether to output by itself or forward data based on the identifier.

[0090] For example, the first device, the second device, and the fourth device are connected in a cascading manner. The first device can send the second sub-display data carrying the identifier 3 to the second device 200 through the first interface 102. After receiving the second sub-display data carrying the identifier 3, the second device 200 can compare the identifier 3 with the identifier allocated to the second device 200. If the comparison result is different, the second device 200 can send the second sub-display data carrying the identifier 3 to the fourth device 400, and the fourth device 400 displays the second sub-display data. That is, the second device 200 only forwards the data and does not display the data.

[0091] In the present application, the third device 300 can be a mobile phone, a computer, an information transceiver device, a tablet device, a personal digital assistant, or the like. The third device 300 can include at least one processor, a memory, at least one network interface, and an input / output device. The various components in the third device 300 are coupled together through a bus system. It can be understood that the bus system is used to realize the connection and communication between the components. In addition to the data bus, the bus system also includes a power bus, a control bus, and a status signal bus.

[0092] The input / output device can include a display, a camera, a keyboard, a mouse, a trackball, a click wheel, a key, a button, a touchpad, a touch screen, or the like.

[0093] It can be understood that the memory can be a volatile memory or a non-volatile memory, and can also include both volatile and non-volatile memories. Among them, the non-volatile memory can be a read-only memory (ROM), a programmable read-only memory (PROM), an erasable programmable read-only memory (EPROM), an electrically erasable programmable read-only memory (EEPROM), a ferromagnetic random access memory (FRAM), a flash memory, a magnetic surface memory, an optical disc, or a compact disc read-only memory (CD-ROM). The magnetic surface memory can be a disk memory or a tape memory. The volatile memory can be a random access memory (RAM) used as an external cache. By way of example but not limitation, many forms of RAM can be used, such as static random access memory (SRAM), synchronous static random access memory (SSRAM), dynamic random access memory (DRAM), synchronous dynamic random access memory (SDRAM), double data rate synchronous dynamic random access memory (DDR SDRAM), enhanced synchronous dynamic random access memory (ESDRAM), sync link dynamic random access memory (SLDRAM), and direct rambus random access memory (DRRAM).The memory described in the embodiments of the present application is intended to include, but not limited to, these and any other suitable types of memory.

[0094] The memory in the embodiments of the present application is used to store various types of data to support the operation of the third device 300. Examples of these data include: any computer programs for operating on the third device 300, such as operating systems and application programs; contact data; phonebook data; messages; pictures; audio; and the like. Among them, the operating system contains various system programs, such as framework layer, core library layer, driver layer, etc., for implementing various basic services and processing hardware-based tasks.

[0097] The first device provided in the present application can have the functions of daisy chain and reverse daisy chain at the same time through device cascading, and can also select part of the data or all the data to transmit to the upper-level device or the lower-level device.

[0099] Here, each display has a camera through which image acquisition can be performed. Among them, the display 1 can send the image 1 acquired by the camera of the display 1 to the display 2; the display 2 can merge the image acquired by the camera of the display 2 with the image 1 to form the image 2 and send the image 2 to the display 3; the display 3 can merge the image acquired by the camera of the display 3 with the image 2 sent by the display 2 to form the image 3 and send the image 3 to the display 4; the display 4 can merge the image acquired by the camera of the display 4 with the image 3 sent by the display 3 to form the image 4 and send the image 4 to the computer 5. That is, each display can merge the image acquired by the camera of the display with the image sent by the previous display and send the image to the next display.
