Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image processing technologies face challenges in achieving both data reduction and reproducibility of image measurement results, particularly when using irreversible compression methods, as the compressed data cannot be restored to its original state, hindering accurate evaluation of measurement conditions.
Innovation Solution
An image processing apparatus and system that includes a compression unit for irreversibly compressing image data, a restoration unit for restoring the compressed data to its original format, and a control unit for storing both the compressed and restored data along with measurement results, allowing for accurate evaluation and comparison.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If irreversible compression is used to reduce data amount, then data storage efficiency is improved, but measurement reproducibility deteriorates
Solution Approach 1:
The patent segments the data management process into three distinct parts: (1) storing the original uncompressed image data, (2) storing the irreversibly compressed image data, and (3) storing measurement results obtained from the restored compressed data. This segmentation allows the system to maintain both compressed and uncompressed versions, resolving the contradiction between data reduction and measurement reproducibility.
Solution Approach 2:
The patent changes the compression parameter from reversible to irreversible to achieve greater data reduction. By accepting the parameter change and implementing a dual-storage system, the patent resolves the contradiction by allowing irreversible compression for storage efficiency while maintaining measurement capability through selective restoration and re-measurement.
2Ease of operation
If irreversibly compressed data is restored, then data format is recovered, but original image quality is lost
Solution Approach 1:
The patent performs preliminary action by storing the measurement results obtained from the restored compressed data together with the compressed data. This allows later evaluation of measurement conditions without needing to restore the original high-quality image, as the measurement results serve as a proxy for the original image quality assessment.
Solution Approach 2:
The patent creates a functional copy by restoring the compressed data to the original format and performing measurement on it. The measurement results serve as a copy of the measurement that would have been obtained from the original uncompressed data, allowing evaluation without requiring the original high-quality image to be preserved.
Data Source
AI summary
The disclosure provides an image processing apparatus, an image processing system, and recording medium capable of achieving both reduction of the amount of data and securement of reproducibility. An image processing apparatus generates compressed image data by compressing raw image data acquired by imaging an object into a JPEG format, restores the compressed image data to restored image data of a bmp format, and then acquires a first result by executing an image measurement processing on the restored image data. The image processing apparatus stores the compressed image data and the first result in association with each other.
