Solution Overview
Problem
Conventional portable skin condition measurement devices face challenges in acquiring clear, entire face images for accurate analysis, particularly in terms of portability, mobility, and the ability to control user face position effectively during image capture.
Innovation Solution
A portable device equipped with a user face capturing camera, processor, and distance sensor that captures images based on various parameters, extracts specific face areas, composes them into an entire face image, and suggests adjusting the face position for optimal image capture, ensuring uniform brightness and accurate analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a conventional device for measuring skin condition is used with fixed user capturing position, then measurement precision is improved, but portability and mobility deteriorate
Solution Approach 1:
The device transitions from a fixed capturing position to a dynamic system that can adapt to various user positions. The processor dynamically adjusts capturing parameters and performs image processing operations to maintain measurement precision regardless of the device's position relative to the user's face.
Solution Approach 2:
The system changes capturing parameters (such as focal length, aperture, or lighting conditions) based on the detected distance between the device and the user's face. This allows the device to maintain image quality and measurement precision across different distances and positions.
2Adaptability or versatility
If a portable device for measuring skin condition is used, then portability and mobility are improved, but the ability to acquire clear entire face image deteriorates
Solution Approach 1:
The device uses multiple images captured from different positions or angles and synthesizes them into a single comprehensive face image. This multi-dimensional approach allows the portable device to capture the entire face clearly even when positioned at various distances or angles.
Solution Approach 2:
The processor acts as an intermediary that receives multiple partial face images, processes them through image synthesis algorithms, and produces a complete high-quality face image. This intermediary processing step bridges the gap between limited portable device capabilities and the requirement for clear entire face imaging.
3Manufacturing precision
If multiple capturing parameters are used to extract specific face areas, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The face image is divided into multiple specific areas (such as forehead, cheeks, chin) that are captured or extracted separately using different capturing parameters. This segmentation allows precise measurement of each facial region while managing the complexity through modular processing.
Solution Approach 2:
Multiple extracted face areas captured with different parameters are merged or synthesized into a single comprehensive face image. This combining process integrates the precise measurements from different regions while producing a unified result for overall skin condition analysis.
