Solution Overview
Problem
Existing technologies face challenges in processing three-dimensional (3D) image data to play 2D, stereo, and multi-view images without losing resolution, particularly when using existing broadcasting infrastructure.
Innovation Solution
An image processing apparatus that receives original left, central, and right images, processes them to generate processed images with reduced vertical resolution, and generates 3D image data including auxiliary and metadata, allowing for encoding and decoding to output images in various modes, including 2D, stereo, and multi-view, while maintaining original resolution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If 3D image data is processed to generate multiple viewpoint images, then image versatility is improved, but data quantity increases
Solution Approach 1:
The patent divides the 3D image data into multiple view images (first view image, second view image, third view image) representing different perspectives. Each view image is processed independently through encoding and decoding operations, allowing the system to generate multiple viewpoint images from segmented data portions without requiring complete original data for all views simultaneously.
Solution Approach 2:
The patent implements a nested structure where processed view images are stored within the 3D image data container. The encoding unit encodes multiple view images, and the decoding unit decodes them to generate multiple viewpoint images. This nesting allows efficient storage and retrieval of multiple views without proportionally increasing overall data quantity, as each view shares the same data structure framework.
2Productivity
If image resolution is reduced for processing, then processing efficiency is improved, but image quality deteriorates
Solution Approach 1:
The patent dynamically adjusts the resolution of view images based on processing requirements. The encoding unit receives view images at their original resolution, processes them through encoding, and the decoding unit reconstructs them at the desired output resolution. This dynamic resolution adjustment allows efficient processing of reduced-resolution intermediates while maintaining original image quality in the final output, resolving the contradiction between processing efficiency and image quality.
Data Source
AI summary
An image processing apparatus that configures a single frame by determining a central image of a certain viewpoint as an original resolution, and frame another single frame by combining a left image of a left viewpoint and a right image of a right viewpoint. The image processing apparatus may generate three-dimensional (3D) image data configured using the frames, and may encode, decode, and render an image based on the 3D image data.
