3D Thumbnail Generation for Seamless Display Merging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 3D display devices lack the capability to generate and naturally merge 3D thumbnails with 3D main images, leading to user confusion and dissatisfaction during 3D image perception.
Innovation Solution
A 3D image providing device and method that selects index frame sets from 3D image data, generates thumbnail frame sets with reduced size and resolution, and combines them with 3D main images for display, using components like index selection units, thumbnail generation units, storage units, image decoding units, and 3D formatters to create a seamless viewing experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If 3D thumbnails are generated from 3D image data, then user satisfaction and reproduction point accuracy are improved, but device complexity increases due to additional processing units
Solution Approach 1:
The device segments the 3D image data into multiple frame sets and selects index frames from these segments to generate thumbnails. This segmentation allows the system to process large 3D image data efficiently while maintaining precision in reproduction point accuracy.
Solution Approach 2:
The patent introduces an intermediary processing pipeline that includes index frame selection units and thumbnail generation units. These intermediary components bridge the gap between raw 3D image data and the final thumbnail output, enabling precise reproduction points without overwhelming system complexity.
2Ease of operation
If thumbnails are merged with 3D main images, then viewer confusion is minimized and natural viewing experience is achieved, but processing time and computational load increase
Solution Approach 1:
The system performs preliminary actions by pre-selecting index frames and pre-generating thumbnails before the actual viewing process. This allows the thumbnail generation to be completed in advance, reducing processing time during playback and enabling seamless merging with 3D main images.
Solution Approach 2:
The patent employs parameter changes by adjusting the resolution and size parameters of thumbnails relative to the main 3D images. By optimizing these parameters, the system achieves natural merging of thumbnails with main images while controlling processing time and computational load.
3Measurement precision
If multiple frame sets are processed to generate thumbnails, then reproduction point accuracy is improved, but processing complexity and resource consumption increase
Solution Approach 1:
The system extracts only the necessary index frames from the complete 3D image data and frame sets. By taking out only the essential frames needed for accurate reproduction points, the system maintains high precision while significantly reducing processing complexity and resource consumption compared to processing all frames.

AI summary
A 3D-image providing device comprises: an index selection unit for selecting at least one index frame set from 3D-image data including plural frame sets; and a thumbnail generation unit for obtaining left and right images for the selected index frame set and generating a thumbnail frame set based on the obtained left and right images, wherein the frames included in the thumbnail frame set satisfy conditions that the sizes and resolution thereof are respectively small and low compared to the frames included in the index frame set. Accordingly, the 3D-image providing device generates 3D-thumbnails from the left and right images of the 3D-image data to provide 3D images considered when moving to a user-desirable reproduction time point. Also, the 3D-image supply device merges the 3D-thumbnails with 3D-broadcasting images or 3D-contents and displays the merged image. Consequently, the image providing device minimizes viewer confusion when perceiving 3D-images and increases user satisfaction.
