Image Processing Apparatus Startup Search Responsiveness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image processing apparatuses, such as electronic cameras, take a long time to become operational after starting up, especially when searching through large numbers of images and directories on memory cards, leading to delayed acceptance of user operations.
Innovation Solution
The apparatus includes a search unit that begins searching file data upon startup and allows operation unit inputs to be accepted before the search is completed, enabling quicker responsiveness during file or directory searches.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the apparatus waits for file search completion before accepting operations, then search accuracy is improved, but operational responsiveness deteriorates
Solution Approach 1:
The search unit performs preliminary search actions during the startup sequence before the operation unit can be activated. The control unit initiates file search operations in advance, so that when users begin interacting with the apparatus, the search is already partially complete or in progress, allowing operations to be accepted without waiting for full search completion.
Solution Approach 2:
The system dynamically adjusts its operational state based on search progress. The control unit monitors search status and operation requests simultaneously, allowing the apparatus to transition between search-only mode and full operation mode. This dynamic approach enables operations to be accepted during search execution, resolving the contradiction between search completion and operational responsiveness.
2Measurement precision
If the apparatus completes file search before startup, then data accuracy is improved, but startup time increases
Solution Approach 1:
The search unit executes preliminary search operations during the startup sequence, before the apparatus is fully ready for user interaction. The control unit initiates file search tasks in the background during startup, so that search operations are already in progress when users begin using the apparatus, effectively reducing perceived startup time while maintaining search accuracy.
Solution Approach 2:
The search operation continues in the background during startup and user interaction without interruption. The control unit maintains continuous search execution alongside normal operations, ensuring that file search accuracy is not compromised while the apparatus becomes operational. This continuous action eliminates the need to wait for search completion before accepting user commands.
3Ease of operation
If the apparatus accepts operations during search, then operational responsiveness is improved, but search reliability deteriorates
Solution Approach 1:
The control unit continuously monitors both search progress and operation requests, using feedback loops to manage the interaction between search operations and user commands. This feedback mechanism allows the system to accept operations during search while maintaining search reliability through continuous status monitoring and coordinated task management.
Solution Approach 2:
The system dynamically manages the relationship between search operations and user commands by adjusting operational priorities in real-time. The control unit can suspend, resume, or modify search operations based on incoming commands, allowing flexible operation acceptance during search without compromising overall search reliability through rigid completion requirements.

AI summary
An image processing apparatus for recording and reproducing an image, comprises: a recording unit that records the image; a search unit that searches file data recorded in the recording unit when the apparatus is started; an operation unit that designates a predetermined operation to the apparatus; and a control unit that enables acceptance of an operation upon designation of the operation by said operation unit during a search of said search unit, even before the search is completed.
