Virtual Space Viewpoint Control Using Focus-State Movement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for shooting in a virtual space do not allow for intuitive viewpoint movement that mimics the focus state of shooting in a real space, lacking a method for easily performing viewpoint movement in an environment with a shallow depth of field.
Innovation Solution
An information processing apparatus that generates a virtual space image, outputs a capture range and focusing markers, and controls viewpoint movement in response to user operations, allowing for intuitive viewpoint movement and focusing adjustments in a virtual space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If viewpoint movement is implemented using VR goggles and controller with markers, then movement control is achieved, but the operation becomes complex and not intuitive for shallow depth of field environments
Solution Approach 1:
The patent copies the focus state information from real-space camera operation to virtual space. When a user operates a focus ring or adjusts focus in real-space camera, the corresponding focus state is replicated in the virtual space image, allowing intuitive viewpoint movement without complex VR controller operations.
Solution Approach 2:
The patent introduces a focus state as an intermediary between the user's physical camera operation and the virtual space viewpoint movement. The focus state acts as a mediator that translates simple focus adjustment actions into meaningful viewpoint changes in the virtual environment.
2Adaptability or versatility
If a marker is selected in VR goggles to achieve viewpoint movement, then movement function is realized, but the marker has no relation to the content focus state making operation non-intuitive
Solution Approach 1:
The patent changes the parameter used for viewpoint movement from marker selection (arbitrary position selection) to focus state (content-related parameter). By using focus state as the control parameter, the system adapts to shallow depth of field environments where focus is the natural way to interact with content.
Solution Approach 2:
The patent copies the focus state from the real-space camera operation to the virtual space image. This copying ensures that the viewpoint movement in virtual space corresponds to the focus state adjustment in real space, making the operation intuitive and content-related rather than arbitrary.
3Productivity
If virtual space image is generated without real camera, then virtual environment shooting is enabled, but depth of field control becomes difficult to observe and operate
Solution Approach 1:
The patent copies the focus state information from real-camera operation to the virtual space image generation process. This allows users to control depth of field in virtual space by simply operating the focus ring on a real camera, maintaining the ease of operation while enabling virtual environment shooting.
Solution Approach 2:
The patent makes the real camera's focus mechanism universal by having it control both real-space and virtual-space focus states. The same focus ring operation affects both the physical camera's focus and the virtual space image's focus state, simplifying the user interface for virtual space shooting.

AI summary
An image processing apparatus includes a generating unit that generate a virtual space image, which is an image of a virtual space, an output unit that outputs a range to be captured in the virtual space and a marker indicating a position in the range to be captured where focusing is performed to a display device, and a control unit that controls the virtual space image so that, in response to an operation of an operation device for performing a movement operation of a viewpoint, which is a position where shooting in the virtual space is performed, in the virtual space, at least one of movement of the viewpoint in a direction indicated by the marker and movement of the viewpoint a distance that the focusing is performed is performed.
