Solution Overview

Problem

3-D videos subjected to image processing may not meet standards like HDMI1.4a, leading to improper delivery or display and potential future compatibility issues.

Innovation Solution

A moving image processing device and method that acquires frame data with parallax images for both eyes across an active space, identifies the active space, and sets its pixel values to fixed values using synchronization signals or a database, ensuring compliance with HDMI1.4a standards.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If image processing is applied to 3-D videos, then image quality and processing capabilities are improved, but compliance with HDMI1.4a standards deteriorates

Engineering Contradiction:
Improveimage processing qualityVSAvoidstandard compliance
Core Design Contradiction:
Manufacturing precisionVSReliability

Solution Approach 1:

The patent divides the frame data into distinct regions: the active space containing parallax images for left and right eyes, and the inactive space. By segmenting the data this way, the invention can apply image processing to the active space while maintaining standard-compliant fixed values in the inactive space, thus resolving the contradiction between processing quality and standard compliance

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies different processing characteristics to different parts of the frame data. The active space undergoes full image processing for quality enhancement, while the inactive space maintains fixed values to ensure standard compliance. This local differentiation allows simultaneous optimization of processing quality and standard adherence

Inventive Principle:
Principle #3Local quality

2Productivity

If active space position is not accurately identified, then processing efficiency is improved, but display correctness deteriorates

Engineering Contradiction:
Improveprocessing efficiencyVSAvoidactive space position accuracy
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

The patent uses synchronization signals (Vsync and Hsync) as feedback references to accurately determine the active space position. The active space setting unit references these synchronization signals to correctly identify and set the active space, ensuring both accuracy and efficiency in the processing

Inventive Principle:
Principle #23Feedback
