Panorama Image Processing Apparatus Viewing Angle Metadata
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for displaying panorama images, such as single view and scroll displays, fail to accurately reflect the user's viewpoint and can result in distortions due to unknown viewing angles, making high-quality projection displays suboptimal.
Innovation Solution
An image processing apparatus that associates panorama image data with information indicating whether it is a full circumference panorama image, allowing for appropriate display processing systems to be selected and enabling accurate projection displays by setting a fixed viewing angle of 360°.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If projection display is used to improve immersion and sense of presence, then display quality is improved, but accurate viewing angle information is required which is difficult to obtain from panorama image data alone
Solution Approach 1:
The patent applies preliminary action by embedding viewing angle information at the time of panorama image creation. The imaging apparatus stores the viewing angle in metadata when capturing panorama images, so that this information is already available when the image is later displayed, eliminating the need for users to manually input or estimate the viewing angle.
Solution Approach 2:
The patent uses metadata as an intermediary carrier that bridges the gap between image capture and display. The viewing angle information is stored in metadata associated with the panorama image data, serving as a mediator that transfers this critical parameter from the imaging phase to the display phase without loss.
2Measurement precision
If manual input of viewing angle is required to ensure accurate projection display, then display accuracy is improved, but operation complexity increases
Solution Approach 1:
The patent implements self-service by enabling the imaging apparatus to automatically record and store viewing angle information in metadata during the panorama capture process. This eliminates the need for users to manually input viewing angle data, as the system performs this function automatically without user intervention.
Solution Approach 2:
The viewing angle information is captured and stored in advance during image acquisition. This preliminary recording of metadata ensures that accurate viewing angle data is already available when display is needed, removing the burden of manual input from the user.
3Area of stationary object
If scroll display is used to show larger portions of panorama image, then visibility is improved, but geometric distortion occurs in projected lines
Solution Approach 1:
The patent applies parameter changes by using the stored viewing angle information to dynamically adjust projection parameters during display. Based on the metadata containing the actual viewing angle, the system can calculate appropriate projection transformations that maintain geometric accuracy while displaying large portions of the panorama image.

AI summary
There is provided an image processing apparatus including an association section configured to, in a case where panorama image data generated by using a plurality of frame image data obtained by an imaging operation while displacing an imaging direction is determined to be a full circumference panorama image, associate the panorama image data with information showing that the panorama image data is the full circumference panorama image.
