Multi-bit Synchronization Signal Recognition for Image Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing systems face challenges in accurately recognizing synchronization signals, especially when noise is present, leading to image misalignment and misregistration due to the use of single-bit synchronization signals.
Innovation Solution
The implementation of a multi-bit signal pattern for synchronization signals, where each color has a distinct pattern, allows for more accurate recognition and generation of output image signals, even in noisy conditions, by using a recognition unit to identify genuine synchronization signals based on embedded patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If single-bit synchronization signals are used, then device complexity is reduced, but measurement precision and reliability deteriorate due to noise interference
Solution Approach 1:
The patent transitions from single-bit synchronization signals to multi-bit signal patterns, adding dimensional complexity to the signal structure. Each color channel (R, G, B) is assigned a unique multi-bit pattern, enabling noise-resistant recognition through pattern matching rather than simple bit detection.
Solution Approach 2:
The invention changes the fundamental parameter of synchronization signals from 1-bit to multi-bit representations. By encoding multiple bits per color channel with distinct patterns, the system achieves better noise immunity and recognition accuracy without proportionally increasing overall system complexity.
2Reliability
If multi-bit signal patterns are used for synchronization, then measurement precision and reliability improve, but device complexity increases
Solution Approach 1:
The synchronization signal is segmented into multiple color channels (R, G, B), each with its own unique multi-bit pattern. This segmentation allows independent recognition of each color channel's synchronization status, improving overall reliability while distributing the processing complexity across separate channel treatments.
Solution Approach 2:
The patent uses replicated pattern structures for each color channel, where each channel has a copied version of the multi-bit pattern encoding scheme. This standardized copying approach simplifies the processing logic despite the increased signal complexity, as the same recognition algorithm applies to each channel.
3Ease of operation
If single-bit synchronization signals are used, then ease of operation is maintained, but image quality deteriorates due to misalignment and misregistration
Solution Approach 1:
The multi-bit pattern recognition system provides feedback mechanisms to verify successful synchronization signal detection. By checking whether received signals match the expected multi-bit patterns for each color channel, the system can detect and correct alignment issues before they manifest as image quality problems.
Solution Approach 2:
The patent performs preliminary synchronization signal validation by comparing received multi-bit patterns against expected patterns before proceeding with image processing. This preliminary check ensures proper alignment and registration is established before main image processing operations begin, preventing quality degradation.
Data Source
AI summary
An image processing device includes a reception unit and a recognition unit. The reception unit receives an input image signal and a synchronization signal including a signal pattern. In a case in which the signal pattern corresponds to a predetermined prescribed pattern, the recognition unit recognizes the synchronization signal as a genuine synchronization signal to be used to generate an output image signal on a basis of the input image signal.
