Solution Overview
Problem
Conventional image capturing technologies face challenges in achieving high spatial and temporal resolutions without compromising optical efficiency, leading to decreased signal-to-noise ratio and increased camera size, which affects image quality and portability.
Innovation Solution
An image data generator that includes a light splitting section, imager sections with photoelectric transducer units, an A/D converter, a spatial frequency calculating section, and a super-resolution section to process and combine analog signals from different wavelength ranges, restoring high-frequency components and optimizing data transfer rates for high-resolution image capture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If high spatial resolution and high temporal resolution are both maximized, then image quality and motion tracking are improved, but data transfer rate becomes excessively high
Solution Approach 1:
The patent segments the imaging process into two distinct paths: one capturing high spatial resolution at low temporal resolution, and another capturing low spatial resolution at high temporal resolution. This segmentation allows the system to process and transmit data at manageable rates while still providing both high-resolution image data and high-frame-rate motion information through separate channels.
2Loss of energy
If data transfer rate is reduced through compression, then device size and power consumption are reduced, but image quality and detail are lost
Solution Approach 1:
The patent merges two separate data streams - high spatial resolution low temporal resolution data and low spatial resolution high temporal resolution data - into a comprehensive output system. This allows the system to maintain full image quality by preserving the high-resolution spatial data while using the high temporal resolution data for motion tracking and interpolation, thereby avoiding information loss despite reduced overall data transfer rates.
3Measurement precision
If multiple imaging sensors are used to capture different wavelength ranges, then color accuracy is improved, but device complexity and size increase
Solution Approach 1:
The patent implements a universal imaging platform where a single camera system can capture multiple wavelength ranges (RGB and infrared) simultaneously through a unified sensor array and processing pipeline. This multi-functional design allows the same hardware to serve multiple purposes - visible light imaging and infrared imaging - without requiring separate dedicated devices, thereby reducing overall system complexity while maintaining color and spectral accuracy.
