Dynamic Object Scaling for Virtual Viewpoint Position Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing techniques for generating virtual viewpoint images from multiple camera captures struggle to intuitively convey the position of an observed point on a virtual space, making it difficult for users to recognize this position effectively.
Innovation Solution
A display controlling apparatus that acquires information about the position of a virtual viewpoint and an observed point, determines the size of objects representing these points based on the distance between them, and controls the display of a second virtual viewpoint image to include these objects, thereby enhancing user recognition of the observed point's position.

Engineering Contradiction Analysis
1Ease of operation
If the position of an observed point on a virtual space is displayed using a fixed-size object, then the display is simple, but the user cannot intuitively recognize the position of the observed point
Solution Approach 1:
The patent applies dynamics by making the size of the object indicating the observed point variable rather than fixed. The object size changes dynamically based on the distance between the virtual viewpoint and the observed point, allowing users to intuitively recognize spatial relationships. When the distance is large, the object appears larger; when the distance is small, the object appears smaller, creating an intuitive visual feedback mechanism.
Solution Approach 2:
The patent changes the parameter of object size based on the distance parameter. By establishing a correspondence relationship between distance and object size, the system transforms the abstract spatial distance into a visible size variation. This parameter change enables users to perceive the position of the observed point more intuitively without adding complex display mechanisms.
2Ease of operation
If the size of the object indicating the observed point is made variable based on distance, then the user can intuitively recognize the position, but the determination of object size becomes complex
Solution Approach 1:
The patent introduces an intermediary mechanism - a determination unit that mediates between the distance calculation and the object size display. This unit receives distance information and automatically determines the appropriate object size, then provides this to the display control unit. The intermediary abstracts the complexity of size determination from the display system, allowing intuitive recognition while managing computational complexity centrally.
Solution Approach 2:
The patent creates a visual copy or representation of the observed point as an object whose size is scaled according to distance. Instead of displaying the actual observed point, the system displays a scaled representation (object) that preserves spatial relationships through size variation. This copying approach simplifies the display while maintaining the intuitive recognition function.
3Ease of operation
If a second virtual viewpoint image is displayed to show the object indicating the observed point, then the user can recognize the position, but additional display control is required
Solution Approach 1:
The patent segments the display into two functional parts: the first virtual viewpoint image showing the main scene, and the second virtual viewpoint image showing the object indicating the observed point. By separating these functions into different display views, the system achieves clear visibility of the observed point position without overcomplicating the main display. The segmentation allows each view to serve its specific purpose optimally.
Solution Approach 2:
The patent adds another dimension to the display by creating a second virtual viewpoint image that complements the first. Instead of modifying the existing view, the system introduces a new dimensional perspective where the object indicating the observed point can be clearly displayed. This dimensional addition provides the necessary information without disrupting the original viewing experience.

AI summary
A display controlling apparatus determines a size of an object indicating an observed point in a case where a distance from a position of a first virtual viewpoint to a position of the observed point is a second distance longer than a first distance, to be larger than a size of the object indicating the observed point in a case where the distance from the position of the first virtual viewpoint to the position of the observed point is the first distance, and performs control of displaying a second virtual viewpoint image corresponding to a second virtual viewpoint different from the first virtual viewpoint, a distance from the position of the first virtual viewpoint to a position of the second virtual viewpoint being a predetermined distance, the second virtual viewpoint image including the object indicating the observed point having a determined size, and an object indicating the first virtual viewpoint.
