Engineering Contradiction Analysis
1Reliability
If a hardware stabilizer is used to implement anti-jitter of a camera, then stability performance is improved, but hardware costs are extremely high
Solution Approach 1:
The patent creates a virtual camera that copies the parameters and behavior of the physical camera, including its jitter characteristics. By smoothing the parameters of this virtual camera copy and using it for rendering, the system achieves stabilization without modifying the physical camera hardware, thereby avoiding the high costs of hardware stabilizers while maintaining stability performance
Solution Approach 2:
The patent replaces the mechanical hardware stabilizer system with a software-based parameter processing system. Instead of using physical components to stabilize the camera, the system uses computational methods to smooth camera parameters (position, orientation, focal length) of a virtual camera, substituting mechanical stabilization with algorithmic parameter smoothing

AI summary
A parameter processing method and apparatus for a virtual camera. The method includes obtaining a camera parameter of a first virtual camera in a virtual scene, the first virtual camera having a binding relationship with a physical camera in a real scene and the physical camera being configured to obtain image data of an object in the real scene, smoothing the camera parameter of the first virtual camera to obtain a target camera parameter; and configuring a second virtual camera in the virtual scene and adjusting a camera parameter of the second virtual camera based on the target camera parameter to obtain an adjusted second virtual camera, a focus of the second virtual camera corresponding to a focus of the first virtual camera, wherein the adjusted second virtual camera is configured for rendering based on the image data to obtain an image of the virtual scene comprising the object.
