Image Pickup Apparatus Automatic Search Interruption Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image pickup apparatuses require users to manually interrupt and restart searching processes, leading to inconvenience and potential missed shutter opportunities, especially when interruptions occur during data communication, memory card changes, or battery replacements.
Innovation Solution
The apparatus includes a change-of-status detecting device that automatically interrupts the searching process upon detecting events like shooting start, memory card insertion, or communication cable mounting, allowing the system to switch to interruption mode without user intervention, and saves interrupted search data for seamless restart.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a search interruption button is used to interrupt the searching process, then the searching process can be interrupted, but the user operation becomes complicated and time-consuming
Solution Approach 1:
The system automatically detects status changes (shutter button press, memory card insertion, communication cable mounting) and autonomously interrupts the searching process without requiring user interaction with a dedicated interruption button. The system serves itself by monitoring its own state and making interruption decisions based on detected events.
Solution Approach 2:
A status change detecting device acts as an intermediary between various operational events (shutter press, card insertion, cable mounting) and the searching process control. This intermediary detects status changes and triggers appropriate interruption actions, eliminating the need for direct user intervention.
2Adaptability or versatility
If the searching process is interrupted during shooting, data communication, or memory card replacement, then the interruption process can be executed, but the user has to manually press the search interruption button first
Solution Approach 1:
The system performs preliminary detection of status changes that indicate the user's intent to perform interruption-triggering operations. By detecting these status changes before the user would need to press the interruption button, the system prepares to interrupt the searching process automatically, saving the user time and effort.
Solution Approach 2:
The system continuously monitors status changes and uses this feedback to automatically control the searching process. When specific status changes are detected (shutter press, card insertion, cable mounting), the system receives feedback about the user's operational intent and automatically adjusts the searching process accordingly.
3Quantity of substance
If the working memory is shared by searching process and interruption process, then memory resources are efficiently used, but the user has to re-input search key image and search result image after interruption
Solution Approach 1:
When the searching process is interrupted, the system creates a copy of the search key image and search result image data and stores it in a dedicated storage device. This copying mechanism preserves the data even when working memory is reused for the interruption process, eliminating the need for re-input after interruption.
Solution Approach 2:
The system performs preliminary saving of search key image and search result image data to storage device before the working memory is overwritten during the interruption process. This preliminary action ensures data preservation while allowing efficient memory resource utilization.
Data Source
AI summary
An image pickup apparatus which is capable of interrupting a data searching process quickly without detecting a user pressing a search interruption button. A system controller circuit carries out a searching process for searching least one desired data from a plurality of data stored in a nonvolatile memory or a memory card. When a change-of-status of the image pickup apparatus is detected, for example, when a shutter button has been pressed halfway, the system controller circuit interrupts the searching process and executes an interruption process.
