Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in accurately correcting distortion and blur in moving images captured using a fisheye lens, as it is challenging to determine the necessary corrections for proper display and editing of wide-angle images obtained through non-central projection methods.
Innovation Solution
An information processing apparatus with distortion correction and blur correction processing units that allow users to control and apply distortion correction and blur correction independently, using posture data from the imaging apparatus to ensure accurate image representation, and the ability to record and reproduce these corrections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If distortion correction processing is applied to convert wide-angle image data into central projection image data, then the image data becomes suitable for standard display and editing, but the processing complexity and time required increase
Solution Approach 1:
The patent applies distortion correction processing in advance during the image recording stage, converting wide-angle image data into central projection image data before storage. This preliminary correction eliminates the need for time-consuming processing during reproduction, as the corrected image data is already in the standard format required for display and editing operations.
2Manufacturing precision
If blur correction processing is applied using posture data, then image clarity is improved, but the device complexity and processing requirements increase
Solution Approach 1:
The imaging device performs blur correction using its own posture data (acceleration and angular velocity information) that it automatically records during image capture. The device serves itself by utilizing its built-in sensors and processing capabilities to correct blur without requiring external correction systems or additional complex equipment.
Solution Approach 2:
The patent employs feedback mechanisms where the imaging device uses its recorded posture data (acceleration and angular velocity) to determine the appropriate blur correction amount. This feedback loop allows the system to automatically adjust correction parameters based on the actual shooting conditions, improving image clarity while maintaining manageable system complexity.
3Manufacturing precision
If both distortion correction and blur correction are applied, then image quality is significantly improved, but the processing time and computational load increase substantially
Solution Approach 1:
The patent combines distortion correction and blur correction processing into a unified correction system that operates simultaneously during the image recording phase. By merging these correction operations and executing them in advance, the system achieves high image quality without imposing significant time delays during reproduction, as both corrections are already applied to the stored image data.

AI summary
It is possible to easily reproduce and edit image data that is a moving image obtained by capturing an image of a non-central projection method, in which distortion correction and blur correction are reflected. For this purpose, an information processing apparatus includes: a distortion correction processing unit that performs distortion correction processing for converting image data as a moving image acquired by capturing an image of a non-central projection method into an image of a central projection method; and a blur correction processing unit that performs blur correction processing of reducing the image blur generated in the image data using posture data of an imaging apparatus for image data that has been subjected to the distortion correction processing. In other words, the blur correction is performed after the distortion correction.
