Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bi-sensor super-resolution techniques require two sensors, lenses, processors, and batteries, increasing complexity and cost, and necessitate identical optical paths, which is costly and complex.
Innovation Solution
Interlacing a first array of pixels with a second array of different pitch to form a repeatable modular block for a dual-array single sensor, avoiding photosensitive area overlap, thus achieving bi-sensor super-resolution capabilities with a single sensor setup.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If two sensors are used for bi-sensor super-resolution, then image resolution is enhanced, but device complexity and cost increase significantly
Solution Approach 1:
The patent merges two separate sensor arrays into a single integrated sensor device. The first and second sensor arrays with different pitches are combined in one sensor package, eliminating the need for two separate cameras, lenses, processors, and batteries. This reduces system complexity while maintaining bi-sensor super-resolution capabilities through the interlaced arrangement of pixels from both arrays.
2Measurement precision
If two sensors are used for bi-sensor super-resolution, then image resolution is enhanced, but cost increases due to multiple components
Solution Approach 1:
The patent combines two sensor arrays into a single sensor device, reducing the bill of materials and manufacturing costs. Instead of requiring two complete camera systems with lenses, processors, and power sources, the invention achieves bi-sensor functionality in one integrated package, significantly lowering both component costs and assembly expenses.
3Measurement precision
If identical optical paths are ensured for both sensors, then measurement accuracy is improved, but device complexity increases due to beamsplitter and calibrated optical setup
Solution Approach 1:
The patent uses a single optical path for both sensor arrays within the same sensor device. Since both sensor arrays are integrated in one sensor package with different pitches, they naturally share the same optical path without requiring beamsplitters or complex calibrated optical setups. This eliminates the optical complexity while maintaining accurate measurement through the interlaced pixel arrangement.
