Image File Chronological Arrangement Without Link Files
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multimedia data generating methods face difficulties in arranging still image files and moving image files in chronological order, especially when link files are deleted, and require separate directories for different standards, leading to compatibility issues and inconvenience in displaying files conforming to multiple standards.
Innovation Solution
An imaging, recording, file management, and display apparatus that records still image files and moving image files according to different standards in separate directories while maintaining association information to analyze and display their recording order, allowing for easy arrangement and display of files in chronological order without creating new files outside the defined standards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If link files are used to associate still image files and moving image files, then chronological arrangement can be achieved, but the system becomes complex and requires separate directories for different standards
Solution Approach 1:
The patent extracts the chronological ordering information from the link file structure and embeds it directly into the attribute information of each image file. This eliminates the need for separate link files and simplifies the file management structure while maintaining the ability to determine chronological order.
Solution Approach 2:
The attribute information in each image file serves multiple functions: it stores both the chronological order information and the association information between still images and moving images. This multi-functional approach eliminates the need for separate link files and reduces system complexity.
2Adaptability or versatility
If separate directories are used for different standards (DCF and AVCHD), then compatibility is maintained, but files cannot be displayed together in chronological order
Solution Approach 1:
The attribute information structure is designed to be universal, containing both chronological order data and association data that work across different file standards (DCF and AVCHD). This allows files from different standards to be displayed together in chronological order without compromising standard compatibility.
Solution Approach 2:
The attribute information acts as an intermediary that bridges files from different standards. By embedding chronological and association information directly in each file's attributes, the system can display mixed-standard files together without requiring a separate link file mechanism.
3Ease of operation
If link files are created in AVCHD directories, then moving image files can be associated with still image files, but files not defined by AVCHD standard must be created in AVCHD folders
Solution Approach 1:
The patent removes the requirement for link files in AVCHD directories by embedding the association information directly into the attribute information of each image file. This eliminates the constraint that files must be created in AVCHD folders and allows greater flexibility in file standard usage.
Solution Approach 2:
Each image file contains its own association information and chronological order data within its attribute information. This self-contained approach eliminates the need for external link files and allows files to be managed independently according to their own standard requirements.

AI summary
An imaging apparatus includes an image generation unit operable to generate image signal of a subject, a recording unit operable to record a first type of image file or a second type of image file to a recording medium based on the image signal generated by the image generation unit, and a controller operable to control the recording unit. The controller controls the recording unit to record the first type of image file at a lower level of a first directory in the recording medium and record the second type of image file at a lower level of a second directory in the recording medium, and record in the recording medium information used to analyze a recording order of the first type of image file and the second type of image file in the recording medium, while relating the information to the second type of image file.
