Recording Apparatus Dynamic Mode Switching for Memory Capacity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable image pickup devices face a limitation in recording capacity due to an upper limit on the number of clips, leading to a situation where new data cannot be recorded even when the memory is not full, despite having sufficient capacity.
Innovation Solution
Implementing a recording apparatus with two modes: a first mode where new data is recorded as a separate unit and a second mode where new data is recorded successively with previously recorded data, with a control section determining the mode based on the number of units already recorded, allowing for effective use of memory capacity by switching to the second mode when the upper limit is reached.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the upper limit number of clips is set to manage data, then the recording apparatus can control the number of units recorded, but new data cannot be recorded when the limit is reached even if memory capacity is not full
Solution Approach 1:
The recording apparatus dynamically switches between first recording mode (separate units) and second recording mode (continuous units) based on the number of clips recorded. When the upper limit number of clips is reached, the system automatically transitions to second recording mode, allowing continued recording by merging new data with existing clips, thus preventing recording termination while maintaining manageable clip counts
Solution Approach 2:
The system changes the recording parameter (mode) based on the current state (number of clips recorded). By monitoring the clip count and switching between different recording modes, the apparatus adapts its behavior to continue recording effectively without being blocked by the upper limit, thereby resolving the contradiction between managing clip numbers and maintaining recording availability
2Ease of operation
If new data is recorded as separate units, then the number of units increases, but the memory capacity is not effectively utilized
Solution Approach 1:
The recording apparatus dynamically adjusts its recording behavior based on the current clip count. When the number of clips is low, it uses first recording mode to create separate units for easy organization. When the upper limit is reached, it switches to second recording mode to merge new data with existing clips, thereby reducing the total number of units and improving memory capacity utilization while maintaining ease of operation through automated mode switching

AI summary
In a recording apparatus, an instruction section instructing start of recording of input data containing video data and/or audio data, a recording section recording, in a first recording mode, the input data in a recording medium as a separate unit from the input data previously recorded and recording, in a second recording mode, the input data in the recording medium successively as one unit with the input data previously recorded when instructed by the instruction section to start recording of the input data, and a control section controlling the recording section so that the input data is recorded in any of recording modes including the first recording mode and the second recording mode are provided, in accordance with number of units the input data recorded in the recording medium.
