Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging apparatuses that simultaneously capture still images and moving images often fail to maintain continuity of moving image data during the still image recording process, leading to potential failures in capturing moving images.
Innovation Solution
The apparatus includes an imaging means for generating both still and moving image data, with a storage system and control means that prioritize transferring moving image data over still image data when storage capacity is low, ensuring continuous moving image recording by managing data transfer based on storage usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If still image data is transferred to the second storage means during moving image recording, then still image storage capacity is improved, but moving image recording continuity is deteriorated
Solution Approach 1:
The patent implements dynamic control of data transfer based on real-time buffer status. The control means monitors the used amount of the first storage means and dynamically adjusts whether to transfer still image data or moving image data to the second storage means, ensuring optimal resource allocation and maintaining moving image recording continuity while maximizing still image storage capacity.
Solution Approach 2:
The patent employs feedback control by continuously monitoring the buffer usage status and using this information to make real-time decisions about data transfer priorities. The control means receives feedback on storage buffer status and adjusts transfer operations accordingly, preventing buffer overflow that would disrupt moving image recording while efficiently managing still image data storage.
2Device complexity
If storage buffer is shared between still image and moving image data, then device complexity is reduced, but reliability of moving image recording is deteriorated
Solution Approach 1:
The patent segments the storage buffer into functionally distinct areas: a first storage means for temporarily holding both still image and moving image data, and a second storage means for permanent storage. This segmentation allows independent management of different data types while using a unified physical storage resource, reducing overall system complexity while maintaining reliability through controlled data transfer priorities.
Solution Approach 2:
The first storage means serves multiple functions: it acts as a temporary buffer for both still image data and moving image data, and its usage is dynamically adjusted based on recording needs. This multi-functional design reduces the need for separate dedicated buffers for each data type, simplifying the storage system architecture while maintaining reliable moving image recording through intelligent control.
