Virtual Camera Control for Game Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In video game devices, the positional relationship between the player object and other objects in a three-dimensional virtual space is not adequately considered in camera control, leading to uncomfortable gameplay experiences, especially with many enemy objects in the game environment.
Innovation Solution
An image processing program and device that controls the virtual camera in a three-dimensional virtual space by selecting objects within a given range of the player object and determining the camera position based on their positional relationship, ensuring the player object and other objects are captured effectively in the two-dimensional image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the virtual camera is controlled to include many enemy objects in the three-dimensional virtual space, then the quantity of objects captured in the image is improved, but the positional relationship between the player object and other objects becomes unclear, worsening the visibility and user comfort
Solution Approach 1:
The patent applies local quality by differentiating the treatment of objects based on their type and relationship to the player. The camera control prioritizes maintaining clear positional relationships for player-enemy interactions while still capturing multiple enemy objects. This is achieved by selectively adjusting camera parameters (position, angle, zoom) based on the spatial distribution and importance of different objects, ensuring that critical positional information remains clear while maximizing the number of visible enemies.
2Ease of operation
If the virtual camera position is controlled based only on player object position, then the ease of operation is improved, but the visibility of positional relationships between player and multiple enemy objects deteriorates
Solution Approach 1:
The patent implements dynamics by making the camera control adaptive and responsive to changing game conditions. Instead of fixed camera positioning, the system dynamically adjusts camera parameters based on real-time object positions, player actions, and enemy distributions. The camera automatically repositions, zooms, and rotates to maintain optimal visibility of positional relationships, transitioning smoothly between different viewing angles and distances as the game state evolves.
3Quantity of substance
If the field of view of the virtual camera is controlled to capture groups of objects, then the quantity of objects captured is improved, but the clarity of individual object positions deteriorates
Solution Approach 1:
The patent applies segmentation by dividing the visual field into different zones or layers, allowing simultaneous capture of multiple objects at different levels of detail. The camera system segments the scene to prioritize certain objects (like enemies near the player) while still including others in the broader view. This may involve selective focus, depth-of-field effects, or hierarchical object importance weighting, where critical objects maintain sharp position clarity while less critical objects are visible but with reduced detail.

AI summary
To provide an image processing device and the like capable of improving visibility of images in a game and so on with respect to a user. A player object operated by the user and plural objects different from the player object are generated in a three dimensional virtual space, and an object existing within a given range including the player object in these plural objects is selected as an object to be imaged, and a position of a virtual camera is determined so that the player object and the object to be imaged are captured into the two dimensional image.
