Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a simple and convenient process to switch camera settings to those suitable for detecting pulse wave information, as existing technologies do not provide an efficient method for this purpose.
Innovation Solution
An image capturing device with an image capturing unit capable of capturing 4K or higher resolution moving images and a selector switch to switch between two image capturing modes, where the second mode provides higher resolution for detecting pulse wave information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the camera uses a fixed image capturing mode for general purposes, then the device structure remains simple, but it cannot provide high-resolution pulse wave detection when needed
Solution Approach 1:
The patent implements a dynamic image capturing mode that can switch between first and second modes based on detection needs. The control unit dynamically adjusts the image capturing unit's resolution settings, enabling high-resolution pulse wave detection when required while maintaining simpler operation during normal use. This dynamic adaptability resolves the contradiction by making the system flexible rather than fixed.
2Measurement precision
If the camera captures high-resolution moving images continuously, then pulse wave information can be detected with high precision, but the data processing burden and power consumption increase
Solution Approach 1:
The system dynamically switches between first and second image capturing modes based on whether pulse wave detection is required. The control unit activates the higher resolution second mode only when pulse wave information needs to be acquired, and uses the lower resolution first mode during normal operation. This dynamic mode switching reduces overall power consumption while maintaining high detection precision when needed.
Solution Approach 2:
The patent changes the resolution parameter of the image capturing unit based on operational requirements. By adjusting the resolution parameter between two distinct modes, the system optimizes the balance between detection precision and power consumption, capturing high-resolution images only when necessary for pulse wave analysis.
3Measurement precision
If manual configuration of camera settings is required for pulse wave detection, then detection accuracy can be optimized, but the ease of operation deteriorates
Solution Approach 1:
The control unit automatically manages the switching between image capturing modes based on detection requirements. When pulse wave detection is initiated, the system automatically switches to the second mode with appropriate settings without requiring manual user configuration. This self-service approach maintains optimized detection accuracy while significantly improving ease of operation.
Solution Approach 2:
The system uses feedback from the detection process to automatically adjust image capturing settings. When pulse wave detection is required, the control unit receives this information and automatically configures the appropriate mode, creating a closed-loop system that optimizes both accuracy and user convenience through automated feedback-driven adjustments.

AI summary
An image capturing device includes: an image capturing unit configured to capture a 4K or higher resolution moving image; and a selector switch configured to switch an image capturing mode in which the image capturing unit captures the moving image from a first image capturing mode to a second image capturing mode, the second image capturing mode providing a higher resolution in detecting an amount of change in pulse wave information representing a pulse wave of a living body in the captured moving image than does the first image capturing mode.
