Imaging Device With Live Finger Position Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing personal authentication devices struggle with guiding users to correctly position their fingers for imaging, particularly when language barriers hinder comprehension of textual and figurative instructions.
Innovation Solution
An imaging device and method that superimposes a first display image based on captured images with a second guidance image, repeatedly capturing and displaying until the finger is correctly positioned, using multiple imaging units and display modes to facilitate accurate placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If textual and figurative guidance is provided to users, then guidance information is conveyed, but language barriers prevent comprehension and correct positioning
Solution Approach 1:
The patent replaces textual and figurative guidance mechanisms with a visual feedback mechanism. The imaging portion captures images of the living body portion, and the display portion shows these captured images to users in real-time, allowing users to visually understand their positioning without relying on language-comprehending instructions.
Solution Approach 2:
The system creates a visual copy of the actual positioning state by capturing images with the imaging portion and displaying them on the display portion. This visual copy serves as intuitive guidance, showing users exactly how their body part appears to the imaging system, enabling self-correction without language barriers.
2Measurement precision
If repeated image capture and display is performed until correct positioning is achieved, then positioning accuracy is improved, but operation time increases
Solution Approach 1:
The system performs continuous or repeated image capture and display operations until the living body portion is correctly positioned. The control portion maintains the imaging and display cycle active, allowing users to observe their positioning in real-time and make adjustments, ensuring high positioning accuracy without arbitrary time limits.
Solution Approach 2:
The system implements a feedback loop where captured images are displayed to users, who then adjust their positioning based on this visual feedback. The determination portion evaluates whether correct positioning is achieved, and the control portion continues the capture-display cycle until proper positioning is confirmed, creating an iterative improvement process.

AI summary
An imaging device includes: an imaging portion that captures an image of a portion of a living body to take in the image; a display portion that displays first and second display images with being superimposed on each other, the first display image being based on the taken-in image, the second display image including guidance regarding a way to place the portion of the living body in a prescribed position; a determination portion that determines whether the portion of the living body is placed in the prescribed position; and a control portion that, until it is determined that the portion of the living body is placed in the prescribed position, causes the imaging portion to newly capture and take in a new image of the portion of the living body and causes the display portion to display an image based on the new taken-in image.
