Endoscope Storage and Restoring Circuit for Data Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Endoscope systems face challenges in efficiently transferring and processing large volumes of image data, leading to increased data transfer time and potential errors in image correction due to the inability to handle compressed data effectively across different processor types.
Innovation Solution
The endoscope system incorporates a storage unit for storing compressed data within the endoscope, a restoring circuit to decompress data, and an image correcting circuit for correcting images using non-compressed data, allowing for efficient data transfer and processing, even when connected to processors that may not support compressed data processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If compressed data is stored in the endoscope to reduce data transfer volume, then data transfer time is reduced, but the processor must support decompression functionality which increases system complexity
Solution Approach 1:
The endoscope performs preliminary compression of correction data before transfer to the processor. The compression is done in advance within the endoscope's storage, so that when data is transferred, it is already in a compact form, reducing transfer time and bandwidth requirements without requiring the processor to handle uncompressed data volumes.
Solution Approach 2:
The patent introduces an intermediary data format and processing layer between the endoscope and processor. The restoring circuit in the endoscope handles compression/decompression, acting as a mediator that protects the processor from dealing with large uncompressed data volumes while still enabling efficient data transfer.
2Productivity
If correction data is transferred in compressed form to save bandwidth, then data transfer efficiency improves, but image correction accuracy may be compromised due to processing errors
Solution Approach 1:
The patent creates a copy of the correction data in compressed form within the endoscope's storage. This compressed copy is then transferred to the processor, which decompresses it for use in image correction. The copying mechanism ensures that the original uncompressed data remains available for accurate correction while the compressed copy enables efficient transfer.
Solution Approach 2:
The compression is performed preliminarily within the endoscope before transfer, ensuring that the data integrity is maintained during compression. The restoring circuit carefully manages the decompression process, ensuring that correction accuracy is preserved while achieving efficient data transfer.
3Manufacturing precision
If the endoscope stores non-compressed correction data to ensure processing accuracy, then image correction quality is maintained, but data transfer volume increases
Solution Approach 1:
The patent segments the correction data into compressed and uncompressed representations. The endoscope stores both compressed correction data (for efficient transfer) and maintains the ability to decompress it (for accurate processing). This segmentation allows the system to optimize for both transfer efficiency and processing accuracy by using the appropriate form at the appropriate stage.
Solution Approach 2:
The system changes the data parameter from uncompressed to compressed format for storage and transfer, then transforms it back to uncompressed for processing. This parameter change enables the system to reduce data transfer volume while maintaining the ability to perform accurate image correction when needed.
