Solid-State Imaging Device Pixel Unit Evidence Capability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies do not effectively enhance the evidence capability of images captured by image sensors, failing to consider the output of the image sensor itself as a factor in authentication.
Innovation Solution
A solid-state imaging device is designed with a pixel unit to generate image information, an information generation unit to create additional information, and an image composition unit to combine this additional information with the image information, thereby enhancing the image's evidence capability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional information is embedded in image data, then evidence capability is improved, but device complexity increases
Solution Approach 1:
The patent merges the image data and additional information into a single integrated data structure. The image processing unit combines the image signal from the pixel unit with additional information (such as identification information, measurement values, or status information) to create composite image data. This merging approach improves evidence capability by ensuring both image content and metadata are processed together, while avoiding the need for separate complex storage and management systems.
Solution Approach 2:
The image processing unit is designed to handle multiple functions: processing image signals, embedding additional information, and outputting composite image data. This multi-functional approach allows a single unit to perform what would otherwise require multiple separate components, thereby improving evidence capability without proportionally increasing device complexity.
2Reliability
If additional information is generated and combined with image information, then authentication capability is improved, but information processing complexity increases
Solution Approach 1:
The pixel unit generates additional information simultaneously with image information, rather than adding it later. This preliminary action ensures that identification information, measurement values, or status information are already prepared and synchronized with the image data before processing begins, reducing the complexity of subsequent information integration and improving authentication capability.
Solution Approach 2:
The pixel unit self-generates additional information required for authentication, such as identification information or measurement values, without requiring external systems. This self-service capability reduces the need for complex external information management systems while improving the reliability and authentication capability of the image data.
