Camera Zoom Control for Attention Target Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When zoom control and non-zoom control are performed simultaneously, there is a challenge in maintaining the visibility of the user's attention target, as it can fall outside the field of view, leading to the user losing sight of the target.
Innovation Solution
An information processing device and method that acquires attention information and performs zoom control based on non-zoom control, ensuring the attention target remains within the camera's field of view by limiting the zoom speed and adjusting the camera's position and angle accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If zoom control and non-zoom control are performed simultaneously, then the camera can capture more detailed information and adjust to user attention, but the attention target may fall outside the field of view causing visibility loss
Solution Approach 1:
The system performs preliminary calculations to determine the expected position of the attention target after zoom and non-zoom control operations. By predicting the target's position in advance and adjusting zoom parameters accordingly, the system ensures the target remains within the field of view before the actual control is executed.
Solution Approach 2:
The system continuously monitors the position of the attention target relative to the field of view boundaries. When the target approaches the boundary during simultaneous zoom and non-zoom control, the system provides feedback to adjust the zoom magnitude, preventing the target from falling outside the visible area.
2Measurement precision
If zoom control is performed aggressively to capture attention target details, then image detail quality improves, but the attention target may move outside the field of view during non-zoom control
Solution Approach 1:
The system dynamically adjusts the zoom control parameters based on the current state of non-zoom control and the predicted movement of the attention target. Instead of using fixed aggressive zoom settings, the zoom magnitude and speed are adapted in real-time to maintain the target within the field of view while still capturing detailed information.
Solution Approach 2:
The system changes zoom parameters (such as zoom magnitude, speed, and timing) based on the relationship between zoom control and non-zoom control operations. By adjusting these parameters dynamically, the system maintains both high image detail quality and stable target tracking.
