Multi-mode Image Sensor Binning for Scene Adaptability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current camera systems have limited adaptability to different scenes, resulting in poor imaging quality due to a fixed image output mode and limited compensation through exposure parameter adjustments.
Innovation Solution
The implementation of an image obtaining method and apparatus that utilize a filter array with minimal repeating units, each containing multiple filter groups with color and panchromatic filters. This allows for output in multiple image modes, including full-size, first binning, and second binning modes, to optimize image quality based on ambient light conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed image output mode is used, then the device complexity is reduced, but the adaptability to different scenes deteriorates
Solution Approach 1:
The patent implements multiple image output modes (full-size mode, first binning mode, second binning mode) that can be dynamically selected based on scene requirements. The system transitions from a fixed output mode to a dynamic selection mechanism, allowing the camera to adapt between different binning configurations depending on lighting conditions and scene characteristics, thereby resolving the contradiction between adaptability and complexity.
Solution Approach 2:
The patent changes the output parameter (image mode) based on input conditions (scene type, lighting). By introducing multiple selectable output modes with different binning configurations, the system can adjust its behavior to match different shooting scenarios, improving adaptability while maintaining manageable complexity through parameter-based control.
2Reliability
If exposure parameters are adjusted to improve imaging quality, then the imaging quality improves, but the loss of time increases
Solution Approach 1:
The patent pre-configures multiple image output modes with different binning settings (full-size, first binning, second binning) that are ready for immediate selection. Instead of adjusting exposure parameters during shooting, the system has pre-prepared modes that can be directly selected based on scene assessment, eliminating the time-consuming parameter adjustment process while maintaining imaging quality.
Solution Approach 2:
The system dynamically selects among pre-configured modes rather than performing real-time parameter adjustments. This dynamic mode selection based on scene characteristics allows the system to achieve optimal imaging quality without the time penalty of continuous parameter tuning, as the appropriate mode is already prepared and can be activated immediately.
3Adaptability or versatility
If multiple image output modes are implemented, then the adaptability to different scenes improves, but the device complexity increases
Solution Approach 1:
The patent implements a dynamic mode selection mechanism that chooses among full-size mode, first binning mode, and second binning mode based on scene requirements. This dynamic approach allows the system to provide high adaptability through multiple modes while managing complexity through automated or streamlined selection logic, rather than requiring complex manual configuration for each mode.

AI summary
An image obtaining method includes outputting an image in at least one of multiple image output modes. The multiple image output modes include a full-size mode, a first binning mode, and a second binning mode. In the full-size mode, a first image is obtained according to a first pixel value. In the first binning mode, a second image is obtained according to a second pixel value and a third pixel value. In the second binning mode, a third image is obtained according to a fourth pixel value and a fifth pixel value.
