Iris Recognition Using Regular and Infrared Cameras
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Iris recognition technologies using infrared cameras produce black and white images, which degrade usability and security, as these images can be easily captured and shared, differing from actual eye images and lacking color representation.
Innovation Solution
An electronic apparatus equipped with both an infrared iris recognition camera and a regular camera, where the regular camera displays a preview image showing the iris area as a color image, enhancing usability and security by preventing unauthorized image capture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an infrared iris recognition camera is used to obtain iris images, then iris recognition accuracy is improved, but the image quality and usability are degraded because the images are in black and white and differ from actual eye appearance
Solution Approach 1:
The system divides the imaging function into two separate cameras: an infrared camera dedicated to iris recognition and a regular camera dedicated to displaying color preview images. This segmentation allows each camera to optimize its specific function without compromise.
Solution Approach 2:
The regular camera acts as an intermediary that captures and displays color preview images of the iris area, providing users with a visual representation that matches their actual eye appearance while the infrared camera performs the actual recognition.
2Productivity
If infrared iris recognition images are displayed on screen, then iris recognition can be performed, but security is compromised because the images can be easily photographed and shared through screen capture
Solution Approach 1:
The regular camera serves as an intermediary that displays color preview images instead of the actual infrared recognition images, preventing users from capturing the real iris data while still providing visual feedback.
Solution Approach 2:
The system creates a color copy of the iris area using the regular camera to display on screen, while the original infrared iris image remains protected and is not displayed, thus preventing unauthorized capture.
3Ease of operation
If only a regular camera is used to display preview images, then usability is improved with color images matching actual appearance, but iris recognition accuracy is reduced
Solution Approach 1:
The system separates the preview display function (regular camera) from the recognition function (infrared camera), allowing each to use the optimal technology for its specific purpose.
Solution Approach 2:
The regular camera performs the dual function of capturing preview images for display and providing visual feedback to users, while the infrared camera specializes in iris recognition.

AI summary
A method and an apparatus for recognizing an iris is provided. The method of recognizing an iris in an electronic apparatus includes displaying a preview image by driving a regular camera, displaying an iris recognition area corresponding to an iris recognition camera in the preview image, determining whether an iris image exists in the iris recognition area, and obtaining image information from the iris recognition camera and performing iris recognition, when the iris image exists in the iris recognition area.
