Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing image processing technologies fail to achieve a novel reproduction effect where a static imaging target object is reproduced as if it were imaged into a dynamic background, with limitations in superimposing images and maintaining positional stability during display.

Innovation Solution

An image processing device comprising a foreground selection circuit, a background selection circuit, and a combination circuit that separates and combines foreground and background images to generate new images, where the foreground image remains stationary while the background appears to move, creating a dynamic effect not achievable with previous technologies.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If an image is superimposed onto another image with both images being dynamic or both being static, then the positional relationship is maintained, but a novel reproduction effect cannot be achieved

Engineering Contradiction:

Improvereproduction effectVSAvoidimage processing complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the source image into a foreground image and a background image, allowing independent processing of each part. The foreground image is extracted and superimposed onto a dynamically changing background, creating a novel reproduction effect where only the background moves while the foreground remains stationary.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent applies dynamics by making the background image dynamic while keeping the foreground image stationary. The background image is changed through various transformations (scaling, panning, zooming) while the foreground image maintains its position, creating a dynamic reproduction effect that was not possible with previous static or uniformly dynamic approaches.

Inventive Principle:

Principle #15Dynamics

2Speed

If both the superimposed image and the background image are made dynamic, then movement is achieved, but the foreground object cannot maintain its positional stability

Engineering Contradiction:

Improvebackground movement speedVSAvoidforeground position stability

Core Design Contradiction:

SpeedVSStability of the object's composition

Solution Approach 1:

The patent separates the image into foreground and background components, allowing the foreground to remain stationary while the background undergoes dynamic transformations. This segmentation enables independent control of motion for each component.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Instead of making both images dynamic or keeping both static, the patent inverts the conventional approach by making only the background dynamic and the foreground stationary. This inversion creates a novel effect where the imaging target object appears to move through a changing background while maintaining its own positional stability.

Inventive Principle:

Principle #13The other way round (Inversion)
