Character Movement Control With Derived Body-Part Posture Images
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing character image generation techniques are limited in their ability to create varied movements and require extensive database accumulation for desired postures, restricting applications like avatars performing complex motions.
Innovation Solution
A system that generates and registers multiple derived part images of a character at different angles or postures, associating them with parameters for varied movement, using a computer to manage these images and integrate them into a distribution image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If only face images are used for character animation, then the system complexity is reduced, but the character movement variety is limited
Solution Approach 1:
The patent segments the character into multiple body parts (head, upper body, lower body, arms, legs) and generates derived images for each segment at different angles and postures. This allows independent animation of each body part, enabling complex character movements while maintaining manageable system complexity through modular image organization.
2Adaptability or versatility
If images for desired postures are accumulated in a database, then the character movement variety is improved, but the data accumulation workload increases
Solution Approach 1:
The patent performs preliminary action by automatically generating derived images for various angles and postures using image generation models, rather than requiring manual accumulation of images in a database. This pre-generation approach creates a comprehensive set of character images in advance, enabling diverse character movements without the time-consuming manual data accumulation process.
3Adaptability or versatility
If multiple derived images are generated and managed, then the character movement variety is improved, but the image management complexity increases
Solution Approach 1:
The patent creates a universal image management system where derived images are generated and stored with standardized parameters (angle, posture, body part). This multi-functional approach allows the same set of derived images to be used for various animation purposes and character movements, simplifying management while enabling diverse character expressions and motions.
Data Source
AI summary
A computer is caused to execute a generation step of generating a plurality of derived images in which a character is drawn at mutually different angles or postures on a basis of an input image including the character, and a registration step of registering the derived image as a distribution image for causing the character to move.
