Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If demosaicing is performed for both first received light data (invisible light) and second received light data (visible light) to generate both types of images, then the camera can provide both visible light images and invisible light images, but computational resources and storage resources are wasted and processing time increases
Solution Approach 1:
The system dynamically adjusts the image generation process based on illuminance conditions. When illuminance is low, only invisible light image generation is performed; when illuminance is high, only visible light image generation is performed. This dynamic adaptation eliminates unnecessary demosaicing operations while maintaining the capability to generate both image types when needed, thus resolving the contradiction between versatility and processing efficiency.
Solution Approach 2:
The system changes the processing parameters (which demosaicing operations to perform) based on the illuminance parameter. By monitoring illuminance levels and adjusting the demosaicing configuration accordingly, the system optimizes processing time while preserving the ability to generate both visible and invisible light images when environmental conditions require it.
2Adaptability or versatility
If demosaicing is performed for both first received light data and second received light data, then both visible light image and invisible light image can be generated, but computational resources and storage resources are wasted
Solution Approach 1:
The system dynamically adjusts resource allocation based on illuminance conditions. By making the demosaicing process adaptive to environmental lighting, the system ensures computational and storage resources are utilized only when necessary, eliminating waste while maintaining full versatility when conditions demand both image types.
Solution Approach 2:
The processing parameters are changed based on illuminance levels. When illuminance exceeds a threshold, the system switches to a mode where only visible light demosaicing is performed, thereby reducing computational and storage resource consumption while preserving the capability to generate both image types when needed.
3Adaptability or versatility
If demosaicing is performed for both first received light data and second received light data, then both visible light image and invisible light image can be generated, but processing time increases
Solution Approach 1:
The system implements dynamic processing based on illuminance conditions. By continuously monitoring illuminance and adjusting which demosaicing operations are performed in real-time, the system minimizes processing time by eliminating unnecessary operations while maintaining the versatility to generate both image types when environmental conditions require it.

AI summary
An image generation device acquires first received light data and second received light data from an image sensor. The image sensor receives invisible light and visible light separately through a filter. The first received light data indicates the received light result of the invisible light. The second received light data indicates the received light result of the visible light. In addition, the image generation device generates an image by performing demosaicing for at least one of the first received light data and the second received light data based on illuminance information. The illuminance information indicates the illuminance of the surrounding environment of the image sensor. When the illuminance is less than a first threshold value, the image generation device generates an invisible light image by performing first demosaicing for the first received light data without performing second demosaicing for the second received light data.
