Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital photographing apparatuses struggle to optimize image acquisition and processing based on varying optical conditions and environmental factors, leading to inefficient power consumption and image quality issues.
Innovation Solution
Incorporating a processor that automatically senses the photographing environment to select or synthesize images from multiple optical systems, such as wide-angle and telephoto, or color and black-and-white, based on illuminance, distance, and mode, to generate optimized output images while reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If image synthesis is performed using multiple optical systems, then image quality is improved, but power consumption increases
Solution Approach 1:
The system dynamically changes operational parameters by switching between single optical system mode and multi-optical system synthesis mode based on photographing conditions (illuminance, distance, mode). This allows optimization of power consumption while maintaining image quality when synthesis is beneficial
Solution Approach 2:
The processor automatically determines whether to perform image synthesis by sensing photographing environment information, eliminating the need for manual user selection. The system self-optimizes power consumption and image quality based on current conditions
2Manufacturing precision
If image synthesis is always performed, then image quality is optimized, but processing time increases
Solution Approach 1:
The system dynamically adjusts processing operations based on photographing conditions. When conditions are favorable for synthesis (adequate illuminance, appropriate distance), synthesis is performed to optimize image quality. When conditions are unfavorable or time is critical, single optical system images are used to reduce processing time
3Adaptability or versatility
If multiple optical systems are used, then adaptability to different photographing conditions is improved, but device complexity increases
Solution Approach 1:
Multiple optical systems (first and second optical systems with different focal lengths or fields of view) are integrated into a single photographing apparatus. The processor selectively uses appropriate optical systems based on photographing conditions, providing universal adaptability across different scenarios while managing complexity through intelligent selection
4Use of energy by moving object
If single optical system is used, then power consumption is reduced, but image quality under varying conditions deteriorates
Solution Approach 1:
The system dynamically selects between single optical system operation and multi-optical system synthesis based on real-time photographing conditions. This dynamic adaptation allows the system to minimize power consumption during normal operation while automatically engaging synthesis capabilities when image quality would benefit from multiple optical inputs
