Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If standalone multispectral imaging sensors are implemented in user devices, then multispectral imaging capability is improved, but cost, size, and power consumption increase
Solution Approach 1:
The patent combines multiple spectral filters (first spectral filter for non-visible range, second spectral filter for visible range) directly on the image sensor to integrate multispectral imaging functionality into the existing camera structure, eliminating the need for separate multispectral sensors and reducing overall device complexity
Solution Approach 2:
The image sensor is designed to perform multiple functions: capturing visible light images through the second spectral filter and capturing non-visible light images through the first spectral filter, allowing a single sensor to replace multiple specialized sensors
2Volume of moving object
If spectral filters are integrated on the image sensor, then device size is reduced, but manufacturing complexity increases
Solution Approach 1:
Different regions of the image sensor are assigned different spectral filter characteristics - the first region has the first spectral filter for non-visible light while the second region has the second spectral filter for visible light, allowing specialized filtering in specific areas without complicating the entire sensor structure
Solution Approach 2:
The patent uses composite spectral filter structures that can be deposited or integrated onto the image sensor in a manufacturable way, combining multiple filtering layers or materials to achieve both non-visible and visible light capture capabilities

AI summary
An image capture device may include a first spectral filter and a second spectral filter arranged so that a panoramic image capture operation captures light filtered by the first spectral filter and light filtered by the second spectral filter in a same region of a combined image and one or more processors to: capture a plurality of images based on the panoramic image capture operation; extract first information and second information from the plurality of images, wherein the first information is associated with the first spectral filter and the second information is associated with the second spectral filter; identify an association between the first information and the second information based on a feature captured in the plurality of images via the first spectral filter and the second spectral filter; and store or provide information based on the association between the first information and the second information.
