Imaging Apparatus Orientation Detection for Polarization Filter Effect
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When an imaging apparatus is rotated from a transverse to a vertical orientation, the polarization filter rotates with it, requiring adjustment of the rotation angle to maintain the original polarization filter effect, leading to an unwanted operational burden on the user.
Innovation Solution
The imaging apparatus includes a detection section to detect its orientation and an image generating section that adjusts the virtual filter angle based on this detection, allowing the generation of images that maintain the original polarization filter effect despite changes in orientation, with operational input options for users to adjust the polarization filter effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the imaging apparatus is rotated from transverse to vertical orientation, then the field of view and composition are adjusted, but the polarization filter rotates integrally causing the polarization filter effect to change
Solution Approach 1:
The patent replaces the mechanical rotation of a physical polarization filter with an electronic solution. The imaging section captures light in multiple polarization directions simultaneously, and the image generating section synthetically creates polarized images through signal processing, eliminating the need for mechanical filter rotation when changing imaging orientation.
Solution Approach 2:
The patent changes the approach from physically rotating the filter angle to electronically adjusting polarization parameters. By capturing multiple polarization components and synthesizing images with different virtual filter angles through signal processing, the system achieves polarization filter effect adjustment without mechanical rotation.
2Adaptability or versatility
If a rotatable polarization filter is used to achieve polarization filter effect, then the polarization direction can be adjusted, but the filter must be manually readjusted when imaging apparatus orientation changes
Solution Approach 1:
The imaging section performs preliminary capture of light in multiple polarization directions simultaneously. This pre-capture of multiple polarization components allows the image generating section to synthesize polarized images for any desired virtual filter angle without requiring subsequent mechanical adjustments, saving time when orientation changes.
Solution Approach 2:
The patent replaces the manual mechanical rotation of the polarization filter with automated electronic synthesis. The system uses signal processing to generate polarized images with different virtual filter angles from the captured multi-polarization data, eliminating manual readjustment time.
3Stability of the object's composition
If the polarization filter rotates with the imaging apparatus, then the structural integrity is maintained, but the polarization filter effect changes requiring user intervention
Solution Approach 1:
The patent replaces the mechanical coupling between the imaging apparatus rotation and polarization filter rotation with an electronic decoupling solution. The imaging section and image generating section work together to provide polarization control independent of physical orientation, maintaining structural integrity while ensuring polarization effect consistency.
Solution Approach 2:
The patent segments the polarization control function from the mechanical imaging apparatus structure. The imaging section captures multi-polarization data while the image generating section independently synthesizes polarized images, separating the polarization control function from physical orientation changes.

AI summary
A polarization filter effect is prevented from being changed due to a change in orientation of an imaging apparatus.An imaging apparatus according to the present technique includes an imaging section including a first pixel capable of receiving light in a first polarization direction and a second pixel capable of receiving light in a second polarization direction different from the first polarization direction, a detection section detecting an orientation of the imaging section, and an image generating section generating, on the basis of signals for the first and second pixels, an image corresponding to a polarization direction corresponding to a detection result from the detection section. Thus, as an image corresponding to a particular polarization direction, that is, an image corresponding to application of a polarization filter effect, an image can be generated that corresponds to a polarization direction corresponding to a change in the orientation of the imaging section.
