Image Processing Apparatus for Wide-Angle to Narrow-Angle Projection Transformation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current image processing systems face challenges in efficiently displaying wide-angle views captured by spherical image capturing devices, as they often result in distorted images when viewed, and existing methods do not effectively manage the transition between high-definition partial images and lower-definition wide-angle views.
Innovation Solution
The system employs an image processing apparatus that converts wide-angle images into different definitions, applies projection transformation to generate narrow-angle images with distinct definitions, and transmits these images to smartphones for superimposition, allowing for improved display of high-definition partial images within the context of lower-definition wide-angle views.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If wide-angle images are transmitted at high definition, then image quality is improved, but data transmission load increases
Solution Approach 1:
The patent divides the wide-angle image into multiple regions of interest (ROIs) and processes each region separately. High-definition processing is applied only to identified ROIs while other areas maintain lower resolution, thereby reducing overall data transmission load while preserving image quality in critical areas.
Solution Approach 2:
The patent applies different image processing qualities to different regions of the wide-angle image. Regions of interest receive high-definition processing with detailed feature extraction, while non-critical regions are processed at lower definition, optimizing the balance between image quality and data transmission requirements.
2Stability of the object's composition
If projection transformation is applied to narrow-angle images, then image integration is improved, but processing complexity increases
Solution Approach 1:
The patent performs projection transformation on narrow-angle images before superimposition onto wide-angle views. By pre-processing the narrow-angle images with appropriate projection transformations (e.g., fisheye to equirectangular), the system ensures proper geometric alignment and integration, reducing the need for complex real-time adjustments during display.
3Manufacturing precision
If high-definition partial images are superimposed on wide-angle views, then display quality is improved, but system complexity increases
Solution Approach 1:
The patent introduces an image processing apparatus that acts as an intermediary between the image capturing device and the display device. This intermediary performs region of interest detection, projection transformation, and selective high-definition processing, thereby simplifying the overall system architecture while maintaining high display quality through centralized processing.

AI summary
An image processing apparatus includes circuitry to: obtain a wide-angle image, the wide-angle image being a part of or entire captured image of an object; convert the wide-angle image into a wide-angle image having a first image definition; obtain a part of the wide-angle image as a narrow-angle image; and apply projection transformation to the narrow-angle image to generate a narrow-angle image having a projection different than a projection of the wide-angle image, the narrow-angle image having a second image definition different than the first image definition of the wide-angle image.
