Solution Overview

Problem

Multiview displays suffer from crosstalk, where portions of different views interfere with each other, leading to a less desirable viewing experience, and crosstalk cancellation operations introduce visual artifacts like ghosting.

Innovation Solution

Adapt the background image by modifying its visual parameters such as color, brightness, or intensity based on the presence and location of crosstalk violations to mask or hide these artifacts.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple views are presented contemporaneously in a multiview display, then a realistic 3D viewing experience is achieved, but crosstalk occurs where portions of different views interfere with each other

Engineering Contradiction:
Improveviewing experience qualityVSAvoidcrosstalk
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts and removes the harmful crosstalk components from the displayed views by identifying regions where views overlap and selectively suppressing or removing the interfering portions, thereby eliminating crosstalk while preserving the main 3D viewing effect

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent applies preliminary processing to the multiview image data before display to pre-compensate for and prevent crosstalk artifacts, by analyzing potential overlap regions and adjusting the view presentation in advance to avoid interference

Inventive Principle:
Principle #9Preliminary anti-action

2Object-affected harmful factors

If crosstalk cancellation operations are applied to reduce crosstalk, then crosstalk is reduced, but visual artifacts like ghosting are introduced

Engineering Contradiction:
ImprovecrosstalkVSAvoidvisual artifacts
Core Design Contradiction:
Object-affected harmful factorsVSObject-generated harmful factors

Solution Approach 1:

The patent converts the harmful visual artifacts generated by crosstalk cancellation into beneficial information by using them as a guide to identify where background adaptation should be applied, thereby transforming the artifact problem into a solution for masking crosstalk through background modification

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

3Reliability

If the background image is adapted by modifying visual parameters, then visual artifacts are masked and image quality is enhanced, but processing complexity increases

Engineering Contradiction:
Improveimage qualityVSAvoidprocessing complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies local quality modification by adapting the background image selectively in specific regions where crosstalk violations occur, rather than uniformly processing the entire image, thereby reducing unnecessary processing complexity while maintaining image quality enhancement where it is most needed

Inventive Principle:
Principle #3Local quality

AI summary

An adaptive background multiview image display system and method provides improved multiview image quality. Systems and methods may involve generating crosstalk data that reduces crosstalk between a first view of subject image and a second view of the subject image. The subject image may be a multiview image to be overlaid on a background image. A crosstalk violation may be detected in the subject image based on the crosstalk data. At least one of a color value or a brightness value of the background image is determined according to a degree of the crosstalk violation to generate the background image. The subject image may then be overlaid on the generated background image.
