Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic apparatuses with stacked image sensors have limited usability as they primarily capture images on a single-block basis, lacking the ability to effectively divide image capture regions for different conditions and generate multiple moving images accordingly.
Innovation Solution
An electronic apparatus that divides an image capture region into multiple regions, sets distinct image capture conditions for each region, and employs a moving image generation unit to produce separate moving images from each region, allowing for varied image capture parameters such as frame rate and gain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the image capture region is divided into multiple regions with different image capture conditions, then the adaptability and functionality of the electronic apparatus is improved, but the device complexity increases due to multiple processing units and control mechanisms
Solution Approach 1:
The image capture region is divided into multiple regions (first region and second region) that can be processed independently with different image capture conditions. This segmentation allows each region to be optimized for specific capture parameters while maintaining overall system functionality.
Solution Approach 2:
The image sensor and processing system are designed to handle multiple functions simultaneously - capturing images in different regions with different conditions, generating multiple moving images from a single sensor, and providing versatile output options for various application scenarios.
2Productivity
If multiple moving images are generated from different regions, then the productivity and information output are improved, but the loss of time and processing overhead increase
Solution Approach 1:
The system continuously captures and processes images in multiple regions simultaneously without interruption, maintaining continuous useful action across all processing channels. This allows parallel generation of multiple moving images without sequential processing delays.
Solution Approach 2:
The system transitions from single-region sequential processing to multi-region parallel processing by adding a spatial dimension to the processing architecture. Multiple moving images are generated simultaneously from different spatial regions, effectively increasing productivity without proportional time increase.
3Measurement precision
If different image capture conditions are applied to different regions, then the measurement precision and image quality are improved, but the device complexity and control difficulty increase
Solution Approach 1:
Different image capture conditions are applied to different regions based on their specific requirements. Each region can have optimized capture parameters (such as exposure time, gain, or resolution) tailored to its local characteristics, improving overall image quality while maintaining manageable control through regional independence.

AI summary
To divide an image capture region into multiple regions for which different image capture conditions are set and to generate multiple moving images corresponding to the multiple regions. An electronic apparatus includes an image sensor that captures first and second moving images in first and second regions of an image capture region on different image capture conditions, the second region differing from the first region, and a moving image generation unit that generates the first and second moving images captured in the first and second regions.
