Camera Control Apparatus for Dynamic Tilt Effect Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional camera systems with a tilt effect struggle to maintain desired focus when the camera position changes, particularly during hand-held imaging, as they require setting tilt amounts for specific areas, which can hinder effective hand-held imaging.
Innovation Solution
A control apparatus for a camera system that includes an image pickup apparatus and a lens apparatus with an optical system capable of tilting the focal plane, featuring an acquiring unit and a control unit to determine the object's position based on instructed information, allowing for the construction of a desired focal plane using a desired tilt effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the camera system uses a fixed tilt amount for specific areas, then the focal plane can be focused on a tilted object plane, but the system cannot adapt when the camera position changes during hand-held imaging
Solution Approach 1:
The patent implements dynamic tilt amount adjustment based on detected camera position changes. The control unit continuously monitors camera position and automatically modifies the tilt amount of the optical system accordingly, transitioning from a static fixed tilt approach to a dynamic adaptive approach that maintains focus accuracy regardless of camera movement
Solution Approach 2:
The patent employs feedback mechanisms where the detected camera position information is fed back to the control unit, which then adjusts the tilt amount of the optical system. This closed-loop control ensures that the focal plane remains accurately focused on the tilted object plane even when camera position changes during hand-held imaging
2Measurement precision
If the system requires manual setting of tilt amount for each specific area, then the focal plane can be constructed for that area, but the ease of operation deteriorates during hand-held imaging
Solution Approach 1:
The patent enables the camera system to automatically determine and adjust tilt amounts based on detected camera position and imaging parameters. The system performs self-adjustment without requiring manual intervention for each specific area, eliminating the need for operators to manually set tilt amounts while maintaining accurate focal plane construction
Solution Approach 2:
The patent automatically changes the tilt parameter based on detected camera position and imaging conditions. The control unit calculates appropriate tilt amounts by analyzing imaging parameters and camera position data, dynamically adjusting the optical system's tilt parameter to maintain focus accuracy without manual operation
