Imaging Apparatus Recording Consistency Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Changing settings such as resolution of the compressing encoding unit during image recording can cause inconsistency, leading to interrupted recording and multiple types of recording data being included in a single file, making it difficult to play back properly.
Innovation Solution
The imaging apparatus manages settings changes by ensuring consistency between the imaging unit and compression encoding unit, preventing interruptions and allowing continuous recording by updating settings to match compatible modes, and notifying clients to re-obtain updated settings values.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If settings of the imaging unit or compression encoding unit are changed during recording, then adaptability is improved, but recording reliability deteriorates due to inconsistency between the two units
Solution Approach 1:
The system checks whether a recording unit exists before allowing settings changes. If recording is in progress, the settings change command is rejected with an error message, preventing inconsistency between imaging and compression encoding settings during active recording operations
Solution Approach 2:
The system provides feedback to the external device by returning error messages when settings changes are attempted during recording. This feedback mechanism prevents unauthorized settings changes that would cause inconsistency and recording interruptions
2Adaptability or versatility
If settings are changed during recording, then adaptability is improved, but manufacturing precision deteriorates as multiple types of recording data are included in a single file
Solution Approach 1:
The system performs a preliminary check to determine if recording is currently in progress before accepting settings change commands. This preliminary verification prevents settings changes that would result in multiple data types being mixed in a single recording file
Solution Approach 2:
The system preemptively prevents settings changes during recording by returning error messages, thereby avoiding the creation of inconsistent recording files that would contain multiple types of recording data

AI summary
There has been a problem that continuous recording of monitoring data may be impeded by inconsistency in setting values, occurring due to changes in settings of an imaging unit or compression encoding unit performed while recording. Provided are a recording source which outputs a stream including compression-encoded video data, instructing means which change a parameter relating to the recording source, according to a command transmitted from an external device connected via a network, and control means which perform control so as to switch whether or not a command by the instructing means as to the recording source correlated with the recording job can be accepted, in accordance with the recording state of the recording job.
