Authenticated Subject Exposure Control in Multi-Person Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging systems struggle to efficiently control exposure based on subject authentication results, particularly when multiple subjects are present, leading to inconsistent and suboptimal imaging conditions.
Innovation Solution
An imaging control system that includes a client apparatus capable of face and human body detection, exposure determination, and authentication processing, which prioritizes exposure control based on successful authentication results to ensure accurate and efficient imaging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If exposure control is applied to all detected subjects, then imaging coverage is improved, but processing time and system complexity increase
Solution Approach 1:
The patent extracts only the authenticated subjects from the set of all detected subjects for exposure control. The exposure control unit applies exposure adjustments solely to subjects that have been successfully authenticated by the authentication unit, excluding unauthenticated subjects from processing. This reduces the number of subjects requiring exposure control while maintaining imaging quality for verified targets.
Solution Approach 2:
The patent performs authentication processing before exposure control. The authentication unit verifies subjects in advance, and only authenticated subjects are subjected to exposure control. This preliminary filtering action reduces the workload of the exposure control unit and optimizes processing efficiency by avoiding unnecessary exposure adjustments for unauthenticated subjects.
2Area of stationary object
If exposure control is applied to all detected subjects, then imaging completeness is improved, but system complexity increases
Solution Approach 1:
The patent extracts authenticated subjects from the complete set of detected subjects. The exposure control unit is configured to operate only on the extracted subset of authenticated subjects, thereby simplifying the control logic and reducing system complexity compared to applying exposure control to all detected subjects regardless of authentication status.
Solution Approach 2:
The patent segments the subject processing into two distinct pathways: authenticated subjects undergo exposure control, while unauthenticated subjects are excluded. This segmentation of the processing flow simplifies the overall system architecture by creating clear conditional branches rather than requiring complex universal processing for all subjects.
3Manufacturing precision
If exposure control is applied continuously, then imaging quality is improved, but energy consumption increases
Solution Approach 1:
The patent extracts only authenticated subjects for exposure control processing. By limiting exposure control to verified subjects rather than continuously processing all detected subjects, the system reduces unnecessary energy consumption while maintaining imaging quality for the target subjects that require authentication.
Solution Approach 2:
The patent applies exposure control partially - only to authenticated subjects rather than to all detected subjects. This partial action approach provides sufficient imaging quality for verified targets while avoiding the excessive energy consumption that would result from continuous exposure control on all subjects including unauthenticated ones.

AI summary
A control apparatus for controlling an imaging apparatus includes a determination unit configured to determine whether at least one subject in an image captured by the imaging apparatus is an authenticated subject, and a control unit configured to, in a case where the determination unit determines that the at least one subject is not an authenticated subject, control exposure of the image by targeting the at least one subject.
