Rotating Movable Platform Imager Inclination Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing photographic apparatuses do not effectively correct for inclination angles when image stabilization is activated, leading to images being captured with the imager in an inclined state, as they do not consider the rotation of the apparatus around its optical axis relative to a level plane.
Innovation Solution
A photographic apparatus with a movable platform and a controller that calculates the inclination angle and performs controlled movements to offset it, maintaining the image sensor's orientation parallel to the gravitational force by rotating the platform within its xy plane movement range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the photographic apparatus performs image stabilization by moving the movable platform or imager, then hand shake correction is improved, but the inclination angle of the apparatus around the optical axis is not corrected, causing the imager to be captured in an inclined state
Solution Approach 1:
The movable platform is made rotatable around the optical axis in addition to its existing translational movement capabilities. This dynamic enhancement allows the platform to actively adjust its orientation by rotating through a predetermined angle range, enabling the imager to be leveled and captured in a non-inclined state while maintaining hand shake correction functionality
Solution Approach 2:
The movable platform is designed to perform multiple functions: it can translate in the x and y directions for hand shake correction, and it can also rotate around the optical axis for inclination correction. This multi-functionality allows a single component to address both hand shake stabilization and inclination leveling, eliminating the need for separate correction mechanisms
2Manufacturing precision
If the movable platform is rotated to correct the inclination angle, then the imager orientation is improved, but the movement range of the movable platform is reduced
Solution Approach 1:
The correction functionality is segmented into two independent degrees of freedom: translational movement in the x-y plane for hand shake correction, and rotational movement around the optical axis for inclination correction. This segmentation allows each movement type to operate within its own optimized range without interfering with the other, maintaining full translational range while adding rotational capability
Solution Approach 2:
The movable platform's movement is extended from two-dimensional translational movement (x and y directions) to three-dimensional movement by adding rotational degree of freedom around the optical axis. This dimensional enhancement allows the platform to correct inclination angles without compromising its translational movement range in the x-y plane

AI summary
A photographic apparatus comprises a movable platform and a controller.The movable platform has an imager that captures an optical image through a taking lens, and is movable and rotatable on an xy plane.The controller calculates an inclination angle of the photographic apparatus, and performs a controlled movement of the movable platform for an inclination correction by rotating the movable platform from an initial state on said xy plane in accordance to a rotation quantity of the movable platform.The controller performs the controlled movement to offset the inclination angle by the rotation quantity, when the photographic apparatus is in a first inclination state.The controller performs the controlled movement to maintain an inclined state where the movable platform is rotated from the initial state in accordance to either the first angle or the negative of the first angle, when the photographic apparatus is in a second inclination state.
