User Terminal Device Image Metadata Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable terminal devices struggle to create realistic and vivid photos by efficiently combining user images with backgrounds, as storing moving images requires significant storage space and results in large file sizes.
Innovation Solution
A user terminal device with a camera unit, controller, storage, and display that generates image metadata to change feature parts of user images, allowing for the creation of smaller, more realistic images by matching background images with object images and storing the metadata for display purposes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a user photographs and stores a background image including the user's appearance as a moving image, then the photo looks more realistic and vivid, but the file size becomes large and requires a lot of storage space
Solution Approach 1:
The patent segments the user image into multiple feature parts (face, body, limbs, etc.) and stores them as separate still images with associated metadata. This segmentation allows the system to reconstruct realistic images by selectively combining these parts without storing complete moving images, thereby reducing storage space while maintaining visual realism.
Solution Approach 2:
The patent creates metadata copies that describe the changes in feature parts across different time points. Instead of storing actual moving image data, the system stores compact metadata representations that can be used to reconstruct the visual changes, significantly reducing file size while preserving the ability to generate realistic images.
2Reliability
If the camera photographs the object at multiple time points to capture feature changes, then the image becomes more realistic, but the processing complexity and time increase
Solution Approach 1:
The patent performs preliminary actions by capturing multiple images at different time points and pre-processing them to extract feature parts and generate metadata. This preliminary processing allows the system to quickly reconstruct realistic images later without requiring extensive processing at the moment of display, thus reducing perceived processing time while maintaining image realism.
Solution Approach 2:
The system automatically detects feature parts, tracks their changes across time points, and generates metadata without requiring manual intervention. This self-service approach streamlines the processing workflow, reducing the time and effort needed to create realistic images from multiple captures.

AI summary
A user terminal apparatus is provided. The user terminal apparatus includes a camera unit configured to photograph an object, a controller configured to detect an object image from an image of the object photographed by the camera unit, generate image metadata used to change a feature part of the object image, and generate an image file by matching the object image with the image metadata, a storage configured to store the image file, and a display configured to, in response to selecting the image file, display the object image in which the feature part is changed based on the image metadata.
