Display Screen Inner Hole Image Processing

Solution Overview

Problem

Conventional screen inner hole boring techniques fail to properly display images within the screen inner hole, often resulting in missing key information due to improper image rendering.

Innovation Solution

An image processing method that determines the presence of key information within the screen inner hole area by calculating pixel variance and mean values, using bilinear or Lanczos interpolation to ensure complete and harmonious image display when key information is present.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If screen inner hole boring technique is used to increase screen ratio, then screen ratio is improved, but image display quality deteriorates with missing key information

Engineering Contradiction:

Improvescreen ratioVSAvoidkey information

Core Design Contradiction:

Area of stationary objectVSLoss of information

Solution Approach 1:

The patent performs preliminary analysis of the inner hole area and peripheral area to detect key information before final image rendering. By calculating pixel variance and comparing it against thresholds, the system proactively identifies important content that would otherwise be lost in the screen inner hole, enabling pre-processing decisions to preserve this information.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent introduces an intermediary processing layer between the original image and the final display. This intermediary system uses pixel variance analysis and comparative algorithms to detect key information in the inner hole area, then applies appropriate processing (such as copying from peripheral areas or adjusting rendering) to ensure key information is preserved while maintaining the screen inner hole design.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Shape

If screen inner hole boring technique is used, then aesthetic design is improved, but image completeness deteriorates

Engineering Contradiction:

Improveaesthetic designVSAvoidimage completeness

Core Design Contradiction:

ShapeVSLoss of information

Solution Approach 1:

The system performs preliminary detection of key information in the inner hole area before final image rendering. By analyzing pixel variance and comparing inner hole area with peripheral area, the system proactively identifies important content that needs to be preserved, enabling pre-processing decisions that maintain image completeness while preserving aesthetic design.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent implements a feedback mechanism where the system analyzes the inner hole area, detects key information through pixel variance comparison, and then adjusts the image rendering accordingly. This feedback loop ensures that key information is identified and preserved, allowing the system to maintain both aesthetic design through screen inner hole and image completeness through adaptive processing.

Inventive Principle:
