Imaging Device Display Switching Period Based on Relevance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging devices face challenges in appropriately controlling the display of items on the screen, with necessary items disappearing or unnecessary items remaining due to the difficulty in setting a display switching determination period based on imaging settings.
Innovation Solution
An imaging device with a display switching determination period setting unit that sets specific periods for each display item based on the relevance to the imaging mode, allowing for high-visibility or low-visibility display states to be controlled dynamically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed display switching determination period is used for all display items, then the control is simple, but necessary display items disappear immediately or unnecessary display items remain on the screen
Solution Approach 1:
The patent applies local quality by assigning different display switching determination periods to different display items based on their relevance to the current imaging setting. High-relevance items (e.g., shutter speed, ISO when imaging settings are adjusted) receive longer determination periods to prevent premature disappearance, while low-relevance items (e.g., battery level, image count) use shorter periods. This differentiated approach resolves the contradiction by maintaining simple overall control while achieving reliable, context-appropriate display behavior for each item.
2Reliability
If the display switching determination period is extended for all items, then necessary display items remain visible longer, but unnecessary display items also remain on the screen unnecessarily
Solution Approach 1:
The system determines the relevance of each display item to the current imaging setting and assigns appropriate determination periods accordingly. When imaging settings are adjusted, high-relevance items like shutter speed and ISO receive extended determination periods to ensure visibility, while low-relevance items like battery level and image count use shorter periods and may be removed. This selective extension resolves the contradiction by maintaining visibility reliability for necessary items while reducing the quantity of visible items by removing unnecessary ones.
3Quantity of substance
If the display switching determination period is shortened for all items, then unnecessary display items are removed quickly, but necessary display items may disappear too soon
Solution Approach 1:
The patent implements local quality by differentiating determination periods based on item relevance. When imaging settings change, the system identifies which items are relevant (e.g., shutter speed, ISO, aperture) and assigns them longer determination periods to prevent premature removal. Unrelevant items use shorter periods for quick removal. This selective approach resolves the contradiction by maintaining a smaller number of visible items while ensuring necessary items remain visible reliably.
