As shown in fig. 1, the image simulation method provided by the present invention can also be applied to a communication system including a terminal device and an electronic device, wherein the terminal device 102 and the electronic device 104 communicate through a data line. The terminal device 102 uploads an image acquired by a camera of the terminal device to the electronic device 104, and the electronic device 104 acquires image information from original data after acquiring the original data in the image; in addition, acquiring configuration information related to the image sensor, calling an image processing module to perform image processing on the original data according to the configuration information and the image information to obtain image simulation data, and synthesizing the image simulation data into a simulation image; and displaying the simulation image. The terminal device 102 may be, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers, or portable wearable devices. The electronic device 104 may be implemented as a stand-alone server or a server cluster comprising a plurality of servers.
The present invention further provides an image simulation system architecture, which can be integrated in the electronic device 104, as shown in fig. 2, and the image simulation system architecture includes: an upper subsystem 21 and a lower subsystem 22. Wherein:
And the upper subsystem 21 is used for receiving input operation of a user and acquiring original data of an image from the terminal equipment. The format of the input image may be any one of raw, jpg, and yuv.

The simulation submodule 222 can abstract concrete submodules into a uniform interface and manipulation manner. The image processing module 224 is configured to perform image processing on the original data according to the configuration information and the image information to obtain image simulation data. The image processing module 224 may be an existing functional module or a module called by the photographing function. For example, the image processing module 224 may be any one of the following: the system comprises an automatic white balance module, an automatic lens shadow correction module, an automatic exposure module, a color noise removal module, a brightness noise removal module, a face detection module, a multi-frame denoising module, a high dynamic range module, a full dynamic range module, a dynamic range enhancement module or a global brightness mapping module.

In the step, a user can import the original data of the image from the terminal equipment through the human-computer interaction interface of the upper subsystem.
S402, the electronic equipment acquires original data from the terminal equipment, and the original data is acquired by an image sensor of the terminal equipment.
In this step, the electronic device receives an input operation by a user, and in response to the operation, raw data can be acquired.
S403, the electronic equipment acquires configuration information related to the image sensor.
In this step, the configuration information related to the image sensor may be an exposure parameter of the image sensor, the exposure parameter including one or more combinations of an exposure time length, a sensitivity, and an exposure compensation value.

In this embodiment, a developer may call at least one of the following image signal processing modules in the image signal processing channel according to a debugging requirement to perform image processing on the original data. In this way, the embodiment can perform parameter simulation on one or more image processing modules of the image data without simulating all the image processing modules, so that problem positioning and targeted testing can be facilitated.
In a possible embodiment, after S405, the method further includes: synthesizing the image simulation data into a simulation image; and displaying the simulation image. Optionally, the format of the simulation image is any one of raw, jpg, yuv.

The embodiment uses the image simulation system to adjust the parameters in the image forming process and generate images in real time, can be convenient for checking and repairing problems, can effectively reduce the degree of dependence of the test on environmental scenes, and greatly improves the working efficiency. On the other hand, for the image simulation system, different functions of different modules need to be debugged in the process of image simulation, and the current chip image signal processor has more functions.
