Innovation Solution
A camera control apparatus that includes detection means for identifying authentication targets, area determination means for defining image areas around each target, state determination means for assessing the image state of each area, order determination means for determining the capture order based on image state assessments, and control means for setting camera parameters to achieve optimal image states for authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automatic camera control is implemented for multiple authentication targets, then authentication efficiency is improved, but determination of which target to focus on becomes difficult
Solution Approach 1:
The patent segments the image into multiple areas corresponding to different authentication targets. Each area is processed independently to determine its state (e.g., brightness, contrast, focus quality). This segmentation allows the system to automatically identify which target should be focused on by comparing the states of different areas, resolving the difficulty of target selection while maintaining efficient automatic control.
2Speed
If sequential capture of multiple authentication targets is implemented, then capture speed is improved, but image quality consistency becomes difficult to maintain
Solution Approach 1:
The patent dynamically adjusts camera parameters (exposure, focus, aperture) for each authentication target based on its specific image state. Instead of using fixed parameters for all targets, the system adapts parameters in real-time during sequential capture. This dynamic adjustment maintains optimal image quality for each target while enabling rapid sequential capture of multiple targets.
