Stereo Image Storage in JFIF Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile communication terminals lack a specific file format for storing stereo images, leading to lower compatibility and inability to efficiently store and display three-dimensional stereoscopic images, as they are stored using the same file structure as two-dimensional images without considering the characteristics of stereo images.
Innovation Solution
The method involves using a JPEG File Interchange Format (JFIF) structure to efficiently store stereo images by inserting the left and right images into specific areas within a JFIF file, with the left image in the image area and the right image in the thumbnail area, and optionally storing difference information in an additional APP Marker area, allowing for efficient storage and display of stereo images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a stereo image is stored using a conventional file structure for two-dimensional images, then the storage method is simple and compatible with existing systems, but the ability to efficiently store and display stereo images is lost
Solution Approach 1:
The patent merges two separate image files (left and right images) into a single JFIF file structure. The left image is placed in the main image area while the right image is placed in the thumbnail area, creating a unified stereo image file that maintains compatibility with existing JPEG processing systems while enabling stereo display functionality.
2Ease of operation
If a stereo image is stored as a single file without special formatting, then file compatibility is maintained, but the ability to divide and display images according to stereo characteristics is impossible
Solution Approach 1:
The patent segments the stereo image into two distinct parts within the JFIF structure: the left image occupies the main image area while the right image occupies the thumbnail area. This segmentation allows processing systems to easily separate and handle each image according to its stereo characteristics while maintaining them as a unified file.

AI summary
Disclosed is a method for storing a stereo image. One file is created by using a JPEG File Interchange Format (JFIF) file structure used for storing a Joint Photographic Experts Group (JPEG) format image and a stereo image can be more simply and efficiently stored and compressed.
