Solution Overview
Problem
Existing methods for controlling virtual lenses in games are monotonous and lack diversity and richness, leading to suboptimal picture composition effects when the angle of the virtual lens changes.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the virtual lens controls are made more diverse and rich, then the picture composition effects are improved, but the control system complexity increases
Solution Approach 1:
The patent implements dynamic control of the virtual lens by making the mechanical arm length adjustable based on object movement velocity. When the object moves faster, the mechanical arm extends to maintain picture composition; when the object moves slower, the arm retracts. This dynamic adjustment provides diverse control methods while managing system complexity through conditional parameter changes.
Solution Approach 2:
The patent changes the parameter of mechanical arm length based on object movement velocity. By correlating velocity with arm length, the system achieves rich and diverse control effects without requiring a completely complex control architecture. The parameter change is driven by simple velocity thresholds, keeping the control logic manageable.
2Manufacturing precision
If the mechanical arm length is adjusted to maintain picture composition, then the picture composition effects are improved, but the device complexity increases
Solution Approach 1:
The patent implements feedback control by continuously monitoring object movement velocity and adjusting the mechanical arm length accordingly. The system measures the object's velocity, compares it against reference values, and automatically adjusts the arm length to maintain optimal picture composition. This feedback mechanism achieves high precision without requiring overly complex manual adjustment systems.
Solution Approach 2:
The virtual lens control system performs self-adjustment based on detected object velocity. The system automatically determines when to extend or retract the mechanical arm without requiring external intervention, achieving precise picture composition through autonomous parameter adjustment.
3Speed
If the virtual lens moves in real-time with object movement, then the sense of velocity and smoothness are improved, but the processing complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-establishing the correlation between object velocity and mechanical arm length. The system prepares control parameters in advance based on detected velocity, allowing the virtual lens to move smoothly without complex real-time calculations during rendering. This pre-computation approach maintains high speed perception while reducing processing complexity.

AI summary
The present disclosure provides a method for controlling a virtual lens. The method includes: determining an object movement velocity and object position information of a virtual object, determining a relative distance between the virtual lens and the virtual object based on the object movement velocity, where the object movement velocity is positively correlated with the length of a mechanical arm of the virtual lens, determining a target position of the virtual lens based on the relative distance and the object position information, and controlling the virtual lens to move to the target position.
