Engineering Contradiction Analysis
1Use of energy by moving object
If the sensor surface area is increased to improve light sensitivity, then light sensitivity is improved, but spatial resolution deteriorates due to fewer pixels per unit area
Solution Approach 1:
The patent applies local quality by differentiating the sensor surface into two distinct regions with different properties: a first sensor region with a first sensor surface area optimized for brightness detection, and a second sensor region with a second sensor surface area optimized for color detection. This allows each region to be tailored for its specific function, with the brightness region having larger area for sensitivity and the color region having appropriate area for spatial resolution, thereby resolving the contradiction between overall light sensitivity and spatial resolution.
2Measurement precision
If the number of color sensor elements is increased to improve spatial resolution, then spatial resolution is improved, but manufacturing complexity increases
Solution Approach 1:
The patent segments the sensor surface into distinct functional regions: a first sensor region for brightness detection and a second sensor region for color detection. This segmentation allows the color sensor elements to be concentrated in a specific area rather than distributed across the entire sensor surface, simplifying the manufacturing process while maintaining high spatial resolution in the color detection region. The segmentation enables independent optimization of each region's characteristics.
3Measurement precision
If the sensor module uses different sensor surface areas for brightness and color detection, then light sensitivity and spatial resolution are improved, but device complexity increases
Solution Approach 1:
The patent implements local quality by creating distinct sensor regions with different surface area characteristics optimized for their specific detection functions. The first sensor region has a first sensor surface area tailored for brightness detection, while the second sensor region has a second sensor surface area tailored for color detection. This localized differentiation achieves high spatial resolution and light sensitivity without requiring complex overall device architecture, as each region independently optimizes its own characteristics.
