Person Identification Under Variable Stage Lighting Conditions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing person identification processing systems struggle to maintain accuracy when the illumination state changes drastically, such as on a stage during a performance, leading to difficulties in tracking performers with mobile cameras.
Innovation Solution
An information processing device equipped with a person identification unit that determines whether the illumination state at the time of image capture is similar to the illumination state during the learning process, and only executes person identification processing when the similarity is confirmed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a large number of applications are displayed in a list format, then users can access a variety of functions, but the screen display becomes cumbersome and requires frequent scrolling
Solution Approach 1:
The patent segments the application list into multiple pages, with each page displaying a limited number of applications (e.g., 5-10 items). Users can navigate between pages using page indicator buttons, which divides the overwhelming single list into manageable segments, reducing screen complexity while maintaining access to all applications.
Solution Approach 2:
The patent introduces a new dimension for navigation by adding page indicator buttons that allow users to move between different pages of applications. This transforms the single-dimensional scrolling list into a multi-dimensional navigation system with page numbers and directional buttons, providing alternative access methods without increasing screen clutter.
2Adaptability or versatility
If a scroll bar is provided for navigating application lists, then users can access applications beyond the visible area, but the screen becomes cluttered and operation becomes complex
Solution Approach 1:
Instead of using a continuous scroll bar that occupies screen space and requires precise positioning, the patent segments the navigation into discrete pages with indicator buttons. Each button represents a specific page, making navigation simpler and more intuitive while reducing screen clutter.
Solution Approach 2:
The patent replaces the mechanical scroll bar interface with a digital page indicator system using buttons. This substitution eliminates the need for continuous scrolling mechanics and replaces it with discrete page selection, simplifying the interaction model and reducing the visual complexity on screen.
3Loss of information
If detailed information is displayed for each application, then users can make informed selections, but the screen becomes crowded and harder to navigate
Solution Approach 1:
The patent extracts detailed application information from the main screen display and places it in a separate popup window or detail view. This allows the main screen to maintain a clean, navigable layout with application icons and basic information, while still providing access to complete application details when users select an application, thus preventing screen crowding.

AI summary
To enable highly accurate person identification processing by executing person identification processing in a case where it is confirmed that an illumination state at the time of capturing an image is similar to an illumination state at the time of capturing a learning image from which collation feature information has been acquired. A person identification unit that inputs a camera-captured image, acquires feature information for person identification from the input image, and executes collation processing between the acquired feature information and the collation feature information to execute the person identification processing is included. The person identification unit determines whether or not the illumination state at the time of capturing the input image is similar to the illumination state at the time of capturing the learning image from which the collation feature information has been acquired with reference to an illumination control program generated in advance, and executes the person identification processing to which the input image is applied in a case where the similarity is determined.
