Solution Overview
Problem
Existing technologies fail to effectively display and quantify blood flow variations before and after specific actions, such as massage, in an easily understandable manner, limiting user feedback on the effectiveness of these actions.
Innovation Solution
An electronic device that acquires first and second pulse wave information from images of a user before and after a specific action, determines a display range for a hue moving image based on this information, and controls the display to visually represent blood flow variations, allowing users to intuitively understand changes in blood flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If blood flow variations are displayed using hatching patterns, then notification of effective body parts is provided, but the visualization is not intuitive and difficult to understand
Solution Approach 1:
The patent applies color changes to visualize blood flow variations. Different colors represent different blood flow states, with warm colors (red, orange) indicating increased blood flow and cool colors (blue, purple) indicating decreased blood flow. This color-coded system provides intuitive visual feedback that is easily understood by users, resolving the contradiction between preserving blood flow information and ensuring ease of understanding.
Solution Approach 2:
The patent transitions from using hatching patterns (2D texture) to using color gradients and intensity variations (adding the color dimension). This dimensional change allows blood flow variations to be represented more effectively through color intensity and hue changes, making the visualization more intuitive while preserving all necessary information about blood flow changes.
2Ease of operation
If pulse wave information is acquired from images, then non-contact measurement is achieved, but the measurement precision is insufficient
Solution Approach 1:
The patent uses optical copying by capturing pulse wave information through images of the body surface. The imaging system creates a visual copy of the blood flow changes, which are then analyzed to extract pulse wave characteristics. This copying approach enables non-contact measurement while maintaining sufficient precision through advanced image processing and analysis algorithms.
Solution Approach 2:
The patent replaces traditional mechanical or contact-based pulse measurement systems with an optical imaging system. By using light-based imaging to capture blood flow variations through changes in light absorption and reflection, the system achieves non-contact measurement while maintaining measurement precision through sophisticated optical detection and signal processing.

Data Source
AI summary
An electronic device includes an information acquisition unit, a display information determination unit, and a display control unit. The information acquisition unit acquires first pulse wave information indicating a pulse wave of a part of a body based on image information of the body in a first image obtained by imaging at least the part of the body, and acquires second pulse wave information indicating a pulse wave of a part of the body based on image information of the body in a second image obtained by imaging the part of the body after the first image has been obtained. The display information determination unit determines a display range of a display color of a display image or brightness corresponding to a blood flow variation of a part of the body based on first pulse wave information and second pulse wave information. The display control unit controls display of the display image by the display color determined based on the display range or brightness and the second pulse wave information.
