360-Degree Image Display Controller Spherical Mapping

Solution Overview

Problem

Current image display devices do not perform image quality processing on 360-degree images, resulting in suboptimal display quality for graphically processed spherical images.

Innovation Solution

An image display device with a controller that maps a 360-degree image from a planar shape to a sphere, performs image quality processing, and displays the processed image, incorporating video and graphics processing to enhance image quality, including edge reduction, contrast optimization, and frame rate control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If image quality processing is not performed on 360 degree images, then device complexity is reduced, but image quality deteriorates

Engineering Contradiction:

Improveimage qualityVSAvoidprocessing complexity

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The controller performs preliminary mapping of the planar 360-degree image to a spherical shape before display, preparing the image in advance for optimal presentation. This preliminary transformation enables subsequent image quality processing to be applied effectively to the spherical-shaped image, resolving the contradiction by preparing the image structure beforehand to facilitate quality enhancement without excessive processing complexity during display.

2Manufacturing precision

If image quality processing is performed on 360 degree images, then image quality is improved, but processing time increases

Engineering Contradiction:

Core Design Contradiction:

Manufacturing precisionVSLoss of time

Solution Approach 1:

The image processing is segmented into distinct stages: first mapping the planar 360-degree image to a spherical shape, then applying image quality processing to the spherical-shaped image. This segmentation allows the system to apply different processing techniques optimized for each stage, improving overall image quality while managing processing time efficiently by breaking down the complex task into manageable steps.
