Solution Overview
Problem
Conventional stereoscopic display methods lack the capability to provide high visibility and effective depth perception, leading to suboptimal user experience.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the zero parallax position is set near the predetermined object (first control), then the visibility of objects between the object and virtual cameras is improved, but the stereoscopic effect and dynamism are reduced
Solution Approach 1:
The patent implements dynamic switching between two control modes (first control and second control) based on user input. The system transitions from a static zero parallax position to a dynamically adjustable position, allowing the display control apparatus to adapt between visibility optimization and stereoscopic effect enhancement by selecting different control modes.
Solution Approach 2:
The patent changes the parameter of zero parallax position between two distinct settings: near the predetermined object in first control, and closer to the viewpoint position in second control. This parameter switching enables the system to resolve the contradiction by adjusting the same parameter (zero parallax position) to serve different functional requirements.
2Measurement precision
If the distance between virtual cameras is set smaller (first control), then the visibility of another object is improved, but the amount of coming out effect is reduced
Solution Approach 1:
The system dynamically adjusts the distance between virtual cameras based on the selected control mode. In first control, a smaller distance is used to improve visibility, while in second control, a greater distance is used to enhance the coming out effect. This dynamic adjustment resolves the contradiction by making the camera distance adaptable to different display objectives.
Solution Approach 2:
The patent changes the parameter of inter-camera distance between two settings: smaller distance in first control for visibility improvement, and greater distance in second control for enhanced stereoscopic effect. This parameter variation allows the system to optimize different aspects of the display based on user needs.
3Object-generated harmful factors
If the zero parallax position is set closer to the viewpoint position (second control), then the stereoscopic effects and dynamism are enhanced, but the visibility of another object is reduced
Solution Approach 1:
The system provides dynamic control over the zero parallax position, allowing users to switch between first control (near the object for visibility) and second control (near the viewpoint for stereoscopic effect). This dynamic positioning capability enables the system to resolve the contradiction by adapting the zero parallax position to the current display priority.
Solution Approach 2:
The patent implements parameter switching of the zero parallax position between two configurations: positioned near the predetermined object in first control to maximize visibility, and positioned closer to the viewpoint in second control to maximize stereoscopic effects. This parameter change strategy allows optimization of different display qualities.

Function Achieved in This Case
This approach improves the visibility and dynamism of objects in stereoscopic displays by adjusting the zero parallax position and inter-camera distance, enhancing the overall stereoscopic effect and user experience.
Implementation Method 1
a position of producing no parallax on a screen of the display apparatus is a first position near the object... control is performed such that the position of producing no parallax is closer to the viewpoint position than the first position is

AI summary
An exemplary information processing apparatus selectively switches between: first control where control is performed such that, in a virtual space, a position of producing no parallax on a screen of a stereoscopic display is a first position near a predetermined object; and second control where control is performed such that the position of producing no parallax is closer to a viewpoint position of virtual cameras than the first position is.
