Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a stacked image sensor is used to capture images on a multiple-block basis, then the image capture capability is improved, but the usability is not sufficiently improved due to lack of region-specific accumulation condition control
Solution Approach 1:
The image sensor is divided into multiple regions (first region and second region) with different accumulation conditions. Each region can independently control its accumulation time, allowing differentiated image capture settings across different parts of the sensor, thereby improving usability while maintaining multiple-block capture capability
Solution Approach 2:
Different accumulation conditions are applied to different regions of the image sensor. The first region uses a first accumulation condition while the second region uses a second accumulation condition, enabling optimized image capture for specific regions based on their individual requirements, thus enhancing overall usability
2Measurement precision
If accumulation conditions are made different between first and second regions, then the ability to check live view image changes is improved, but the device complexity increases
Solution Approach 1:
The accumulation conditions for different regions are made dynamically adjustable through a control unit that can modify accumulation times based on live view image changes. This allows the system to adapt accumulation conditions in real-time without requiring complex hardware modifications, balancing measurement precision with device complexity
Solution Approach 2:
The patent changes the accumulation time parameter differently for the first and second regions. By adjusting this single parameter independently for each region, the system achieves improved live view image change detection capability while avoiding the need for complex structural modifications
3Manufacturing precision
If multiple accumulation conditions are set for different regions, then image quality is improved, but the operation complexity increases
Solution Approach 1:
The control unit automatically manages the different accumulation conditions for first and second regions based on live view image analysis. The system self-adjusts the accumulation parameters without requiring manual configuration for each region, thereby maintaining high image quality while reducing operational complexity for the user

AI summary
To make a difference between respective accumulation conditions of first and second regions of a live view image and then to check the live view image for changes in an image corresponding to the changes in the accumulation conditions of the respective regions. An electronic apparatus includes an image-capture unit and a system control unit. The image-capture unit includes an image sensor and captures an image of first and second regions. The system control unit causes a display unit to display a live view image corresponding to the image of the first and second regions captured by the image-capture unit. The system control unit also makes a difference between respective accumulation conditions of the first and second regions of the live view image.
