Those skilled in the art can easily understand other advantages and effects of the present application from the content disclosed in this specification. The present application can also be implemented or applied through other different specific implementation manners. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present application. It should be noted that, without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0053] It should be noted that the illustrations provided in the following embodiments only schematically illustrate the basic concept of the present application. Therefore, only the components related to the present application are shown in the drawings, rather than being drawn according to the number, shape, and size of the components in actual implementation. The types, quantities, and proportions of the components in actual implementation can be arbitrarily changed, and the component layout type may also be more complex.

[0054] The following embodiments of the present application provide a virtualized image processing method, system, storage medium, and electronic device, which implement the function of camera image processing through a software model.

[0055] Figure 1 It is shown as the overall principle structure diagram of the virtualized image processing system 100 in this embodiment; as Figure 1 shown, this embodiment provides a virtualized image processing system 100, and the virtualized image processing system 100 includes: a virtual main board 110, a camera model 120, a transmission interface controller model 130, an image signal processing model 140, and a basic function model 150.

[0056] Figure 2 It is shown as the specific principle structure diagram of the virtualized image processing system 100 described in this embodiment; as Figure 2 shown, the basic function model 150 at least includes a CPU (Central Processing Unit) model 151, an I2C (Inter-Integrated Circuit) control model 152, and a DDR (Double DataRate) model.

[0057] Among them, the virtual main board 110 is constructed through a virtualization platform.

[0058] In this embodiment, the virtualization platform is but not limited to (Quick EMUlator, virtual operating system simulator), SNPS VDK (Synopsys VoIP Development Kit, software development kit), Intel Simics (Intel full-system virtual machine), etc. Among them, in this embodiment, the virtual main board 110 is constructed through the QEMU virtualization platform.

[0059] QEMU is a general-purpose, open-source computer emulator and virtual platform that supports full-system emulation. It can support architectures such as x86 (the computer language instruction set executed by the microprocessor), RM (a LINUX command to delete files or directories in a directory), MIPS (Million Instructions Per Second, the average execution speed of single-word fixed-point instructions), PowerPC (Performance Optimization With Enhanced RISC–Performance Computing, a central processing unit with a reduced instruction set (RISC) architecture), and RISC-V (an open-source instruction set architecture based on the reduced instruction set principle), and also supports operating systems such as Windows (Microsoft Windows operating system), Linux (operating system kernel), FreeRTOS (embedded real-time operating system), and VxWorks (real-time operating system). The upper-layer software runs without any modification on the virtual platform.

[0060] Among them, the QEMU virtualization platform is built-in with multiple device model modules for constructing a virtual mainboard. For example, device model modules such as CPU, DDR, interrupt controller, serial port, I2C controller, ISP (Image Signal Processing), MIPICSI (MIPI CSI-2, Camera Serial Interface) controller, and camera. When constructing the virtual mainboard, the required device models such as CPU, DDR, interrupt controller, serial port, I2C controller, ISP, MIPI CSI controller, and camera are connected through corresponding interfaces, and the address space and interrupt numbers of each device model module are allocated, and finally a virtual mainboard 110 similar to a hardware embedded mainboard is formed.

[0061] Specifically, in this embodiment, the virtual mainboard 110 is an embedded SoC virtual mainboard 110. That is, in this embodiment, QEMU is used to build a complete embedded SoC virtual mainboard 110, including necessary components such as a CPU model, an I2C control mode, and a DDR model 153.

[0062] Among them, the operating systems supported by the virtual mainboard 110 include Windows, Linux, FreeRTOS, and VxWorks.

[0063] In this embodiment, the virtual mainboard 110 includes a driver loading module that loads the drivers of the camera model 120, the transmission interface controller model 130, the image signal processing model 140, and the basic function model 150.

[0064] Therefore, the virtualized image processing system 100 in this embodiment can start a complete Linux or other operating systems such as ARM64 on a virtual platform, and can also load device drivers such as cameras, I2C controllers, MIPI CSI controllers, and ISPs on the virtual platform.

[0065] In this embodiment, components such as the camera model 120, the transmission interface controller model 130, and the image signal processing model 140 are developed and constructed using, but not limited to, the C language, and the camera model 120, the transmission interface controller model 130, the image signal processing model 140, and the virtual main board 110 are integrated.

[0066] In this embodiment, constructing components such as the camera model 120, the transmission interface controller model 130, and the image signal processing model 140 is to simulate the functions of the hardware using software, implement its input / output and register access control, and make its external software interface consistent with that of the real hardware.

[0067] In this embodiment, the camera model 120 is communicatively connected to the virtual main board 110 and reads pictures from a folder at a preset address to simulate the shooting function of a real camera.

[0068] Specifically, in this embodiment, as Figure 3 shown, the camera model 120 includes: a picture reading module 121, a first register sub-module 122, and an I2C interface sub-module 123.

[0069] Among them, the picture reading module 121 reads pictures from a folder at a preset address (the picture storage folder 160) to simulate the shooting function of a real camera; the first register sub-module 122 simulates the configuration and reading / writing of camera registers; the I2C interface sub-module 123 is used to simulate communication with the I2C control model 152 through the I2C interface to control the register sub-model through the I2C control model 152.

[0070] As Figure 4 shown, the camera model 120 further includes: a test color bar generator module 124, which simulates the generation of color bar test images with different resolutions.

[0071] Among them, the test color bar generator module 124 simulates the basic functions of a hardware camera and is used for simulating the debugging of the camera, mainly testing whether the data path is normal.

[0072] Therefore, the camera model 120 in this embodiment can implement the following functions of a hardware camera:

[0073] 1) Function configuration register

[0074] 2) An I2C interface to support the I2C controller to read and write the camera registers;

[0075] 3) A test color bar generator to generate color bar test images of different resolutions

[0076] 4) Read picture files from a specified folder to simulate the image capture function of real hardware.

[0077] In this embodiment, the transmission interface controller model 130 is communicatively connected to the virtual motherboard 110 and the camera model 120 respectively, receives the picture from the camera model 120, and forwards the received picture to the image signal processing model 140.

[0078] In this embodiment, the transmission interface controller model 130 is but not limited to a MIPI CSI controller (MIPI CSI-2, Camera Serial Interface) model. For example, it can also be a DVP (Digital Video Port), SPI Image Signal Processing, or interface controller model.

[0079] Specifically, in this embodiment, as Figure 5 shown, the transmission interface controller model 130 further includes: a second register module 131 and a picture forwarding module 132.

[0080] Among them, the second register module 131 simulates the serial interface register configuration and register reading and writing; the picture forwarding module 132 receives the picture from the camera model 120 and forwards the received picture to the image signal processing model 140.

[0081] In this embodiment, the MIPI CSI controller model can implement the following hardware camera serial interface functions:

[0082] 1) Function configuration register;

[0083] 2) Receive the picture data sent by the camera model 120 and forward it to the subsequent image signal processing model 140.

[0084] In this embodiment, the image signal processing model 140 is communicatively connected to the virtual motherboard 110 and the transmission interface controller model 130 respectively, processes the picture received from the transmission interface controller model 130, and sends the processed picture to the double data rate synchronous dynamic random access memory model for storage.

[0085] Specifically, in this embodiment, as Figure 6As shown, the image signal processing model 140 at least includes one of the following modules: a picture format conversion module 141, an automatic white balance adjustment module 142, an automatic focus module 143, and a color correction matrix module 144.

[0086] Therefore, the image signal processing model 140 of this embodiment can implement the following hardware ISP functions:

[0087] 1) Picture format conversion;

[0088] 2) Automatic white balance adjustment;

[0089] 3) Automatic focus;

[0090] 4) Color correction matrix.

[0091] The working process of the virtualized image processing system 100 of this embodiment is as follows:

[0092] Start the operating system on the virtual motherboard 110, load the drivers of each component, initialize each virtual model, configure the functions, and check whether the camera model 120 can obtain the picture data from the folder 160 storing the pictures. After data stream transmission and ISP processing, finally put the processed picture data into the DDR, and check whether the picture data meets the expectations.

[0093] Therefore, the virtualized image processing system 100 of this embodiment can use a complete software model solution to implement the complete functions of each component such as the camera, MIPI CSI, and ISP. A complete picture processing application of camera -> camera serial interface -> image signal processing can be developed inside the operating system. Various different operating systems can be started on the software virtual development board, and the development of a complete camera data stream application is supported. The drivers, operating system, and applications of each component can run directly on the real hardware without any modification.

[0094] As Figure 7 shown, this embodiment also provides a virtualized image processing method, which is applied to the virtualized image processing system 100 as described above. The method includes:

[0095] Step S100, the virtual motherboard 110 starts the operating system and loads the drivers of the camera model 120, the transmission interface controller model 130, the image signal processing model 140, and the basic function model 150;

[0096] Step S200, make the camera model 120 read pictures from a folder at a preset address to simulate the shooting function of a real camera;

[0097] Step S300: Let the transmission interface controller model 130 receive the picture from the camera model 120 and forward the received picture to the image signal processing model 140;

[0098] Step S400: Let the image signal processing model 140 process the picture received from the transmission interface controller model 130 and send the processed picture to the double data rate synchronous dynamic random access memory model for storage.
