Skin Pore State Analysis Using Multi-Wavelength Fluorescence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for detecting porphyrins in skin images only display regions where porphyrins are detected, making it difficult to distinguish between normal pores and pores without porphyrins, or to determine if porphyrins are present in pores without abnormalities.
Innovation Solution
An information processing device and system that include a display control unit to distinguish between abnormal pores, such as those with porphyrins or porphyrin precursors, and normal pores, using image analysis to differentiate based on pixel values from images taken with different wavelength lights, and display this information in a controlled manner.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If only regions with detected porphyrins are displayed, then the detection purpose is achieved, but the ability to distinguish normal pores from abnormal pores is lost
Solution Approach 1:
The patent segments the skin image into multiple categories: pores with porphyrins, pores with porphyrin precursors, and normal pores. This segmentation is achieved by analyzing pixel values at pore positions and comparing them against threshold values, allowing each pore type to be identified and displayed separately, thus preserving complete pore state information while maintaining detection accuracy
Solution Approach 2:
The patent applies local quality analysis by examining pixel values specifically at detected pore positions rather than analyzing the entire image uniformly. By comparing pixel values at each pore position against threshold values, the system provides localized characterization of each pore's state, enabling distinction between normal and abnormal pores while maintaining overall detection precision
2Loss of information
If detailed pore state information is displayed, then understanding of pore conditions improves, but display complexity increases
Solution Approach 1:
The patent uses color changes to represent different pore states in the displayed image. Pores with porphyrins, pores with porphyrin precursors, and normal pores are displayed in different colors, allowing detailed pore state information to be conveyed through a visually intuitive and relatively simple display mechanism without requiring complex presentation formats

AI summary
The present technology relates to an information processing device, an information processing system, and a program which enable a state of pores to be understood in further detail.A photographing unit photographs skin of a person irradiated with first light of a first wavelength band or second light of a second wavelength band different from the first wavelength band. A pore detecting unit detects pores in a first skin image, which is an image obtained by photographing the skin of the person irradiated with the first light. A porphyrin detecting unit detects a pore state of the skin of the person based on pixel values of a plurality of color components of each of pixels of a second skin image, which is an image obtained by photographing the skin of the person irradiated with second light. A display control unit distinguishes pores in which an abnormality is detected and normal pores based on a detection result of the pores and the pore state of the skin of the person and control display of the pore state of the skin of the person. The present technology can be applied to a system for analyzing a pore state of skin, for example.
