Dual Camera Parallax Correction via Posture-Aware Synthesis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Panoramic image pickup using double-sided cameras often results in unintended camera operator reflection or parallax due to displacement between front and rear cameras, leading to suboptimal image synthesis.
Innovation Solution
An image generation apparatus and method that includes a component image generation unit to associate posture information with images from cameras having different optical axes, a synthesis image generation unit to combine these images, and an image pickup mode changer to switch between compound eye and single eye synthesis modes, allowing for seamless image stitching and correction of parallax.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If panoramic image pickup is carried out using double-sided cameras, then the camera operator can be captured in the front side camera, but unintended reflection or parallax appears due to displacement between front and rear cameras
Solution Approach 1:
The patent introduces an image synthesis unit as an intermediary that processes images from both front and rear cameras. This unit applies synthesis processing to combine the images while correcting for the displacement between cameras, thereby eliminating parallax and unwanted reflections while preserving the ability to capture the camera operator.
2Area of stationary object
If images are picked up using cameras with different optical axes, then more comprehensive coverage is achieved, but parallax and misalignment occur in the synthesized image
Solution Approach 1:
The patent employs feedback mechanisms where the system detects the optical axis differences between cameras and uses this information to adjust the synthesis processing. By feeding back the alignment information into the synthesis unit, the system can compensate for parallax and maintain high alignment accuracy while preserving wide coverage.
3Area of stationary object
If compound eye synthesis mode is used to connect images from multiple cameras, then comprehensive panoramic coverage is achieved, but complexity in image processing increases
Solution Approach 1:
The patent divides the image synthesis process into distinct segments: the front camera captures the operator, the rear camera captures the scene, and the synthesis unit combines them. By segmenting the processing into modular steps (capture, align, combine), the system achieves comprehensive panoramic coverage while managing processing complexity through structured organization.

Methods and apparatus provide for generating a component image in which, with images picked up using a front side camera and a rear side camera built in portable equipment, posture information of the portable equipment is associated; combining a plurality of component images between which the posture of the portable equipment is different to generate a synthesis image; changing over an image pickup mode between a double-sided synthesis image pickup mode in which a synthesis image of one half circumference picked up by the front side camera and a synthesis image of one half circumference picked up by the rear side camera are connected to each other to pick up a synthesis image of a whole circumference and a single-sided synthesis image pickup mode in which a synthesis image of a whole circumference is picked up by each of the front side camera and the rear side camera.
