Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If image is intercepted from user's view angle in 360-degree panorama, then the method is relatively simple, but the image quality cannot be controlled and the formed photo is different from camera photo
Solution Approach 1:
The patent creates a virtual copy of the camera system within the VR environment. A virtual camera is instantiated in the VR scene with identical or enhanced capabilities compared to the physical camera, allowing users to capture images through the virtual camera rather than simply intercepting viewport images. This copying approach preserves operational simplicity while enabling professional-quality image control through the virtual camera's parameter adjustments.
Solution Approach 2:
The patent enables users to adjust camera parameters such as focal length, aperture, shutter speed, and other photographic settings within the VR environment. By allowing parameter changes in the virtual camera system, users can control image quality and achieve professional photography results while maintaining the intuitive VR interaction model.
2Manufacturing precision
If composition design and professional parameter adjustment are added to 360-degree panorama, then satisfactory target picture can be obtained, but the device complexity increases
Solution Approach 1:
The patent introduces a virtual camera as an intermediary between the user and the image capture process. This virtual camera acts as a mediator that translates user interactions and parameter adjustments into professional-quality image captures. The intermediary approach allows complex photography functions to be accessed through a simplified VR interface, reducing the perceived complexity for users while maintaining high photo quality.
Solution Approach 2:
The virtual camera system is designed to be universal, combining multiple camera functions and parameters in a single integrated system within the VR environment. Rather than requiring separate systems for composition design, parameter adjustment, and image capture, the virtual camera provides all these functions through one unified interface, reducing overall system complexity while enhancing photo quality capabilities.
3Adaptability or versatility
If virtual camera is created in VR scene to simulate photography process, then composition design and parameter adjustment are enabled, but the processing time and computational resources increase
Solution Approach 1:
The patent pre-configures the virtual camera with essential photography parameters and composition settings before the actual capture moment. By establishing the virtual camera system and its parameters in advance within the VR scene, the system reduces real-time processing requirements during image capture, thereby minimizing processing time while maintaining full camera control capabilities.

AI summary
A storage medium, and a method and system for simulating photography in a virtual reality scene. The method comprises: firstly, in a virtual reality scene, adjusting composition parameters of a current viewport to obtain initial image data; then, adjusting camera parameters of the initial image data to obtain modified image data; and finally carrying out anti-distortion processing on the modified image data to output a target image. The demands of users for personalizing a 360-degree panoramic photo and outputting satisfying target images are satisfied. The method is not only simple to be operated, but also conducive to the further promotion and application of virtual reality technology.
