VR Image Display Control With Captured-Image Boundary Restriction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing VR content display technologies cause visibility issues and difficulty in adjusting the viewing area due to unrestricted display of areas outside the captured image, leading to drastic image rotations and user discomfort.
Innovation Solution
An image processing apparatus that restricts the viewing area to include only the upper and lower ends of a captured image, transforming a hemispherical image into a planar image and displaying it on a display while omitting the central area, using a processor and memory to execute operations for changing the display range and controlling the display accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the viewing area is not restricted, then the end of the captured image can be verified at the center, but areas outside the captured image are displayed causing drastic image rotation and deterioration in user visibility
Solution Approach 1:
The patent extracts and removes the harmful areas outside the captured image from the viewing area. By defining the viewing area to be restricted within the captured image boundaries, the patent eliminates the black-filled areas that cause drastic image rotation and visibility deterioration, while still allowing verification of the captured image content.
Solution Approach 2:
The patent applies different display characteristics to different regions. The viewing area is locally restricted to the captured image region, while the areas outside are excluded. This local restriction prevents the harmful effects of displaying black-filled areas while maintaining the ability to verify captured image content within the restricted viewing area.
2Object-affected harmful factors
If the viewing area is restricted within the captured image, then image rotation is prevented, but the end of the captured image located in the center cannot be verified
Solution Approach 1:
The patent implements dynamic control of the viewing area. The viewing area can be adjusted and repositioned within the captured image, allowing users to dynamically navigate to and verify the center region containing the end of the captured image. This dynamic adjustment capability resolves the contradiction by enabling verification without causing image rotation.
Solution Approach 2:
The patent introduces an intermediary mechanism for controlling the viewing area. Users can interact with the display to adjust the viewing area position, serving as a mediator between the user's verification need and the restricted viewing area. This intermediary control allows verification of central regions while maintaining the restriction that prevents image rotation.
3Adaptability or versatility
If the viewing area is freely changeable, then user flexibility is improved, but the operation becomes difficult and requires large rotation degrees
Solution Approach 1:
The patent changes the parameters of the viewing area control. By restricting the viewing area to be within the captured image boundaries, the patent reduces the range of motion and rotation degrees required for operation. This parameter change maintains user flexibility for adjusting the viewing area while significantly reducing operation difficulty.

AI summary
An image processing apparatus includes: a processor; and a memory storing instructions which, when executed by the processor, cause the image processing apparatus to: execute receiving processing for receiving an operation of changing a display range for an image displayed on a display; and execute display control processing for performing control based on the operation, the control being performed to transform an image of a predetermined range in a hemispherical image into a planar image and to display the planar image on the display. In the display control processing, the control is performed to display, in the display range, an area included in the planar image and corresponding to a predetermined area at least including an upper end position or a lower end position of the hemispherical image but not to display the area at a position of a center of the display range.
