Dynamic Effect Region Selection via Capture Distance

Solution Overview

Problem

Existing effect processing methods in image and video production face challenges such as fixed display modes, single interaction effects, long pre-production periods, poor performance, and unstable effects, particularly when using pre-constructed interaction-type effects.

Innovation Solution

The method involves obtaining a first image with a target object and a second image displayed on top of the first image, determining a target image region in the second image based on the capture distance and object position of the target object, and displaying at least part of the first image's content in this region to create an effect image.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If pre-constructed interaction-type effects are used to process the original image, then interaction between the target object and the effect is enabled, but the pre-production period is long and the effect performance is poor and unstable

Engineering Contradiction:

Improveinteraction capabilityVSAvoidpre-production period

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-defining multiple fixed effect regions in the effect image before actual use. These effect regions are prepared in advance with different capture distance ranges and corresponding effect elements, so that during runtime the system only needs to match the current capture distance to the pre-defined ranges, eliminating the need for real-time complex calculations or pre-production of custom effects for each interaction scenario.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent utilizes parameter changes by dividing the effect processing into discrete capture distance ranges (first range, second range, etc.), where each range corresponds to specific effect elements. By changing the capture distance parameter, the system automatically selects different pre-defined effect regions, enabling versatile interaction effects without requiring long pre-production periods for each specific effect configuration.

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If effect elements are added to the target object in the original image, then interaction between the effect element and the target object is realized, but the display mode is relatively fixed and the interaction effect is single

Engineering Contradiction:

Improveinteraction effect varietyVSAvoiddisplay mode flexibility

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies segmentation by dividing the effect image into multiple fixed effect regions (first effect region, second effect region, etc.), where each region corresponds to a specific capture distance range. This segmentation allows different effect elements to be displayed in different regions based on the capture distance, enabling diverse interaction effects without requiring complex dynamic display mode adjustments.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces another dimension by utilizing the capture distance as an additional parameter for effect selection. Instead of relying solely on fixed display modes or complex interactions, the system adds the spatial dimension of capture distance to determine which effect region to activate, thereby simplifying the display complexity while expanding interaction effect variety.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Adaptability or versatility

If the capture distance is applied to determine the target image region, then the effect image is correlated with the capture distance and interaction is enhanced, but the system requires detection and processing of distance conditions

Engineering Contradiction:

Improvecapture distance correlationVSAvoiddistance condition processing

Core Design Contradiction:

Adaptability or versatilityVSDifficulty of detecting and measuring
