3D Image Recording Device Viewpoint Flexibility Processing Load
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for reproducing 3D images from MPO files can only display 3D images from a predetermined viewpoint, and increase image processing load, making it difficult to display 3D images from various viewpoints in real-time.
Innovation Solution
An image recording device that records images from different viewpoints along with their corresponding depth information and viewpoint positions, allowing for the generation and storage of additional virtual images, which reduces image processing load and enables real-time 3D image reproduction from various viewpoints.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If virtual images are generated using trilateration from multiple 2D images, then 3D images can be reproduced from various viewpoints, but image processing load increases and real-time display becomes difficult
Solution Approach 1:
The patent pre-generates virtual images from multiple viewpoints during the image recording phase and stores them in the image file. This preliminary action eliminates the need for complex real-time trilateration calculations during reproduction, enabling both viewpoint flexibility and real-time display performance.
Solution Approach 2:
The patent prepares multiple virtual images in advance to cushion against the computational demands of real-time processing. By having pre-computed images ready, the system avoids the harmful effect of high processing load during actual reproduction, ensuring smooth real-time display from various viewpoints.
2Quantity of substance
If only left-eye and right-eye images are stored in MPO file, then file size is reduced, but 3D images can only be viewed from predetermined viewpoint
Solution Approach 1:
The patent pre-generates and stores multiple virtual images from different viewpoints in the image file. This preliminary preparation allows the reproduction device to select appropriate images based on the actual viewing position, providing viewpoint flexibility without requiring excessive data storage.
Solution Approach 2:
The patent dynamically selects which virtual images to generate and store based on expected viewing positions. This dynamic approach optimizes the balance between file size and viewpoint flexibility by only preparing images that are likely to be needed, rather than storing all possible viewpoint images.

AI summary
The image recording device includes: an image information obtaining unit obtaining a first image of the object viewed from a first viewpoint, a second image of the object viewed from a second viewpoint, and viewpoint positions each for one of the viewpoints; a depth information generating unit generating depth information items each indicating a depth of the object included in the first and second images; an image generating unit generating a third image and a viewpoint position of the third image, using the depth information items, the first image, and the second image, the third image being of the object viewed from a third viewpoint different from the first and second viewpoints; and a recording unit recording on the image file the first, second and third images in association with the viewpoint positions each for one of the first, second, and third images.
