Solution Overview

Problem

Existing graphics processing technologies face challenges in efficiently blending graphical content rendered at different pixel densities, leading to suboptimal visual quality and increased computational load.

Innovation Solution

A method and apparatus for blending rendered bins with different pixel densities by storing first and second rendered bins in memory, where the second bin extends beyond the first boundary, and generating a blended region with a third pixel density between the two, optimizing the blending process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If graphical content is rendered at different pixel densities in neighboring bins, then productivity is improved through efficient rendering, but manufacturing precision deteriorates due to visible boundaries and quality transitions

Engineering Contradiction:
Improverendering efficiencyVSAvoidvisual quality continuity
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The patent applies preliminary action by pre-rendering over-rendered regions beyond bin boundaries before the blending operation. This allows the blending process to seamlessly integrate regions with different pixel densities, preventing visible boundaries while maintaining rendering efficiency. The over-rendered regions are prepared in advance to ensure smooth transitions.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent uses blending as an intermediary process between regions rendered at different pixel densities. The blending operation acts as a mediator that smoothly transitions between high-density and low-density regions, eliminating visible boundaries while preserving the efficiency benefits of differential rendering.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Manufacturing precision

If over-rendered regions extend beyond bin boundaries, then manufacturing precision is improved through smoother transitions, but device complexity increases due to additional blending operations

Engineering Contradiction:
Improveboundary smoothnessVSAvoidblending process complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent applies segmentation by dividing the blending operation into distinct stages: identifying over-rendered regions, determining blend regions, and performing blending operations. This segmented approach manages complexity by breaking down the blending process into manageable, organized steps while achieving smooth boundary transitions.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies local quality by applying blending operations selectively only to regions where pixel density transitions occur, rather than processing the entire frame. This localized approach reduces overall device complexity while maintaining boundary smoothness where it is most needed.

Inventive Principle:
Principle #3Local quality

3Manufacturing precision

If blending operations are performed to integrate regions with different pixel densities, then manufacturing precision is improved, but use of energy increases due to additional processing

Engineering Contradiction:
Improvevisual qualityVSAvoidcomputational energy
Core Design Contradiction:
Manufacturing precisionVSUse of energy by moving object

Solution Approach 1:

The patent applies partial action by performing blending operations only on specific blend regions where pixel density transitions occur, rather than processing the entire rendered frame. This selective blending reduces computational energy consumption while maintaining visual quality in the critical transition zones.

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

The patent reduces energy consumption by pre-identifying and preparing over-rendered regions and their corresponding blend regions before executing the blending operation. This preliminary preparation optimizes the blending process, reducing the computational energy required during the actual blending stage.

Inventive Principle:
Principle #10Preliminary action
