3D Game Lens Pose Control for Precise Picture Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 3D mobile games face challenges in accurately controlling lens translation and rotation due to limitations in screen swipe distance and inconsistent direction adjustments, leading to inaccuracies in capturing high-quality game pictures.
Innovation Solution
A method and apparatus for displaying captured pictures in 3D mobile games that allow users to adjust lens pose through touch operations on a plane perpendicular to the lens orientation, enabling precise translation and rotation adjustments without relying on screen swipes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If screen swipe operation is used to control lens translation and rotation, then the operation can be performed on the terminal screen, but the swipe distance is limited and the direction adjustment is inconsistent, leading to low positioning precision
Solution Approach 1:
The patent changes the control dimension from 2D screen swipe to 3D spatial interaction. The lens operation control allows users to adjust lens pose along three orthogonal axes (translation and rotation) through touch gestures on the captured picture, enabling precise positioning in three-dimensional space without being constrained by limited screen swipe distance.
Solution Approach 2:
The patent introduces a lens operation control as an intermediary interface between the user and the lens. This control element, displayed on the captured picture, serves as a mediator that translates user touch operations into precise lens pose adjustments, resolving the inconsistency between swipe direction and lens adjustment direction.
2Area of stationary object
If the lens operation control is displayed on the captured picture, then the control area is expanded and operation is more intuitive, but the control elements may overlap with important picture content
Solution Approach 1:
The patent applies local quality by making the lens operation control semi-transparent or adaptable in display. The control elements are rendered with transparency or can be moved to non-intrusive positions, allowing important picture content to remain visible while still providing access to lens control functions.
Solution Approach 2:
The patent implements dynamic behavior where the lens operation control can be moved to different positions on the captured picture based on user interaction or system determination. The control adapts its position to avoid overlapping with critical picture content while remaining accessible for operation.

AI summary
Embodiments of this application disclose a method for updating a captured picture in a game application performed by a computer device. The method includes: displaying, on a graphical interface, a first captured picture of a game scene of a game application and a lens operation control in the first captured picture; and displaying a second captured picture in response to a touch operation performed by a user on the lens operation control, the second captured picture being obtained by adjusting a pose of a lens within a plane where the lens is located based on the touch operation and capturing a picture of the game scene of the game application with the pose-adjusted lens, and the plane where the lens is located being a plane that is perpendicular to an orientation of the lens.
