Roe Maturity Determination via Light Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for determining the maturity of roe, such as pollack roe, rely on sensory evaluation by humans, leading to inconsistent results and difficulty in precise classification.
Innovation Solution
A roe maturity determination device that uses light irradiation, image capture, and image processing to determine maturity based on light transmissive values, including lightness, color saturation, and hue, allowing for uniform and stable classification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sensory evaluation by human operators is used to determine roe maturity, then the process is simple and requires minimal equipment, but the determination results vary between persons and precision is poor
Solution Approach 1:
The patent replaces the mechanical/sensory evaluation system (human touch and visual inspection) with an optical measurement system. Light irradiation means illuminates the roe, image pickup means captures the transmitted light image, and determination means analyzes the image to objectively determine maturity based on light transmissive values, eliminating human subjectivity while maintaining operational simplicity.
Solution Approach 2:
The patent introduces light as an intermediary substance to transfer information about roe maturity. Instead of direct human contact or visual inspection, light passes through the roe and carries optical property information that is captured by the image pickup means, enabling indirect but precise measurement of maturity characteristics.
2Productivity
If manual classification is performed by operators, then flexibility in handling different roe types is maintained, but productivity is reduced and labor costs increase
Solution Approach 1:
The patent replaces manual classification operations with an automated optical measurement and determination system. The light irradiation means, image pickup means, and determination means work together to automatically assess maturity without human intervention, significantly increasing productivity while maintaining the ability to handle various roe types through programmable determination criteria.
Solution Approach 2:
The determination system performs self-assessment of roe maturity without requiring human operators. The system automatically irradiates light, captures images, processes the optical data, and determines maturity levels, enabling the classification process to serve itself and eliminating dependency on manual labor for routine classification tasks.
3Reliability
If visual inspection is used to assess roe maturity, then equipment requirements are minimal, but determination uniformity cannot be achieved across different operators
Solution Approach 1:
The patent replaces variable human visual inspection with a standardized optical measurement system. The light irradiation means provides consistent illumination, the image pickup means captures uniform images, and the determination means applies consistent criteria to all samples, ensuring that every roe is evaluated under identical conditions and eliminating operator-to-operator variability.
Solution Approach 2:
The patent transitions from subjective visual parameters (human perception of color, texture, and appearance) to objective optical parameters (light transmissive values, brightness, color saturation). This parameter transformation enables quantitative and uniform measurement of maturity characteristics that can be consistently reproduced across different measurement instances and operators.

Function Achieved in This Case
The device enables consistent and precise determination of roe maturity, improving the quality control of roe products by automating the classification process and reducing human error.
Implementation Method 1
light irradiation means that irradiates the roe loaded on the loading portion with light; image pickup means that takes an image of light irradiated from the light irradiation means and passing through the roe
Data Source
AI summary
Roe W is loaded on a loading tray 6, the roe W is irradiated with light from light irradiation means 11, and an image of at least a part of the roe W irradiated with light from the light irradiation means 11 is taken by image pickup means 12. Image processing of the image Pa taken by the image pickup means 12 is performed to measure a light transmissive value of the light passing through the roe W; and maturity of the roe W is determined based on the measured light transmissive value. This enables a roe maturity determination device and a roe maturity determination method capable of determining precisely roe maturity.
