Selective Additional Information Recording for Multi-Media Video Cameras
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing recording apparatuses for business video cameras require significant time and labor to delete additional camera settings information from one recording medium when simultaneously recording moving images on multiple media, as this information is sensitive and not intended for external disclosure.
Innovation Solution
A recording apparatus with a mode setting unit that allows users to independently choose whether to record additional information files, such as image quality adjustment data and user input information, on each of multiple recording media during the recording process, enabling selective exclusion of this information from one medium.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional information is recorded on all recording media simultaneously with moving images, then data completeness and reliability are improved, but the time and labor required to delete sensitive information from media given to editors increases
Solution Approach 1:
The patent applies preliminary action by recording a flag indicating whether additional information is recorded at the beginning of the additional information file. This allows the editing apparatus to automatically identify and handle sensitive information without requiring manual deletion, thus resolving the contradiction between maintaining data completeness and reducing deletion time
Solution Approach 2:
The patent uses copying by creating a metadata flag that copies the recording status information. This flag is written to the additional information file to indicate whether sensitive additional information is present, enabling automatic identification and handling during editing without manual intervention
2Reliability
If additional information is recorded on multiple recording media, then data redundancy and reliability are improved, but the complexity of managing and securing sensitive information increases
Solution Approach 1:
The patent applies segmentation by separating the management of additional information into distinct components: a flag indicating recording status and the actual additional information content. This segmentation allows the editing apparatus to selectively access only the flag information to determine whether sensitive data is present, simplifying the management and security handling of sensitive information across multiple media
Solution Approach 2:
The patent uses an intermediary approach by introducing a flag as a mediator between the recording apparatus and the editing apparatus. This flag serves as an intermediate indicator that communicates the presence or absence of sensitive additional information without exposing the actual sensitive content, thereby reducing management complexity and enhancing security
3Ease of operation
If additional information is recorded on recording media given to editors, then operational simplicity is maintained, but information security and confidentiality are compromised
Solution Approach 1:
The patent applies preliminary action by pre-recording a flag in the additional information file that indicates whether sensitive information is present. This allows the editing apparatus to automatically identify and securely handle sensitive information before any editing operations begin, maintaining operational simplicity while preventing unauthorized disclosure
Solution Approach 2:
The patent uses feedback by having the editing apparatus read the flag from the additional information file and automatically adjust its processing accordingly. When the flag indicates sensitive information is present, the editing apparatus can implement appropriate security measures, creating a feedback loop that maintains both operational simplicity and information security
