Digital Camera Preview Interface for Intuitive Setting Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of digital photographing apparatuses face difficulties in easily and effectively applying photograph setting values to match various shooting environments, as existing systems lack intuitive methods for adjusting settings like exposure, iris, shutter speed, and white balance.
Innovation Solution
A method and apparatus that generate and display preview images with different setting values based on user selection or automatic scene recognition, allowing users to select and apply optimal setting types and values for specific photography scenes, such as night, beach, portrait, landscape, or sport scenes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If automatic setting adjustment is used, then operation simplicity is improved, but adaptability to various shooting environments deteriorates
Solution Approach 1:
The system displays preview images that provide visual feedback to users about how different setting values will affect the final photograph. Users can see the impact of exposure, iris, shutter speed, and white balance adjustments before actually taking the shot, enabling informed decision-making while maintaining ease of operation.
Solution Approach 2:
The system performs preliminary rendering of multiple preview images with different setting combinations before the user makes a final selection. This advance preparation allows users to compare various settings and their effects without waiting for actual photo capture, improving both ease of operation and environmental adaptability.
2Adaptability or versatility
If multiple setting options are provided, then adaptability to shooting environments is improved, but device complexity increases
Solution Approach 1:
The system segments the complex setting adjustments into distinct, manageable components (exposure, iris, shutter speed, white balance) that can be independently adjusted and previewed. Each setting type has its own control interface and preview display, making the overall complex system more manageable and easier to navigate.
Solution Approach 2:
The system adds a temporal dimension to setting adjustment by showing preview images that display the effect of different settings before final capture. This extra dimension (preview before action) allows users to understand complex settings without increasing the complexity of the control interface itself.
3Ease of operation
If preview images with different settings are generated, then ease of setting selection is improved, but processing time increases
Solution Approach 1:
The system generates preview images with only the most relevant setting variations based on the detected shooting environment and user preferences. Rather than exhaustively rendering all possible setting combinations, it focuses on generating a selective subset of previews that are most likely to be useful, reducing processing time while maintaining ease of selection.
