3D Object Thumbnail Generation for Omnidirectional Content
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices face challenges in distinguishing between omnidirectional content with a 360-degree viewing angle and 2-dimensional content using only thumbnail images, as users find it difficult to differentiate between the two based on distorted panoramic or circular thumbnail images.
Innovation Solution
The electronic device generates and displays thumbnails by deforming images based on viewpoint changes, mapping them to 3D objects, and segmenting them to create partial images, allowing users to easily differentiate between omnidirectional and 2-dimensional content through controlled display modes such as rotate, planet, overclock, sphere, and time-slice modes.

Engineering Contradiction Analysis
1Shape
If thumbnail images are generated using distorted panoramic or circular shapes, then the visual representation of omnidirectional content is created, but users cannot easily distinguish whether the content is omnidirectional or 2-dimensional
Solution Approach 1:
The patent applies dimensionality change by mapping 2D images to 3D objects (sphere, cube, cylinder) to create thumbnails that preserve spatial relationships and provide visual cues about the omnidirectional nature of the content. This allows users to distinguish content type while maintaining visual representation.
Solution Approach 2:
The patent segments the thumbnail generation process into multiple steps: obtaining deformed images from different viewpoints, mapping them to 3D objects, and combining them to create comprehensive thumbnails that convey content type information while maintaining visual appeal.
2Loss of information
If multiple deformed images are obtained and mapped to 3D objects to create comprehensive thumbnails, then content type differentiation is improved, but the processing complexity and time increase
Solution Approach 1:
The patent applies preliminary action by pre-obtaining deformed images from different viewpoints and preparing them for mapping before the thumbnail generation event occurs. This preprocessing reduces the computational burden during actual thumbnail creation, balancing quality with efficiency.
Solution Approach 2:
The patent uses partial action by selecting specific viewpoints and creating a limited set of deformed images that are sufficient to convey content type information, rather than processing all possible views. This reduces processing time while maintaining differentiation capability.

AI summary
Various embodiments of the present invention relate to a device for displaying content and an operation method therefor. An electronic device of the present invention comprises a display device, at least one processor, and a memory coupled to the processor, wherein, the memory may store instructions that, when executed, cause the processor to obtain at least one deformed image corresponding to a viewpoint change on the basis of an image contained in content in response to detection of a thumbnail generation event for the content, map the obtained at least one deformed image to a three-dimensional object, obtain at least one partial image comprising at least a portion of the image mapped to the three-dimensional object, generate thumbnail content comprising the obtained at least one partial image, and control the display device to display the thumbnail content. Other embodiments may be possible.
