Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image processing technologies require significant calculation to express character motions in video games and computer graphics, leading to high processing loads that exceed the capabilities of home-use game machines and other limited systems.
Innovation Solution
An image processing apparatus that generates character motions by blending sample motion information with arbitrary ratios, using virtual spheres to determine reachable positions and adjust blend ratios for accurate motion representation, thereby reducing processing loads.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If surface data over a wide range is used to express character motion appropriately, then motion accuracy is improved, but processing load increases beyond the capability of home-use game machines
Solution Approach 1:
The patent divides the continuous surface data into discrete sample points distributed over the wide range. Instead of processing all surface data, only these segmented sample points are used for motion calculation, reducing processing load while maintaining accuracy through strategic point selection
Solution Approach 2:
The patent pre-calculates and stores motion information at discrete sample points before runtime. During actual character motion, the system retrieves and blends pre-computed motion data from these sample points rather than calculating from raw surface data, significantly reducing real-time processing requirements
2Productivity
If preliminary calculation is performed to reduce processing load, then processing speed is improved, but motion accuracy may deteriorate due to reduced calculation detail
Solution Approach 1:
The patent changes the parameter representation from continuous surface data to discrete sample points with associated motion information. By transforming the data structure and using blend ratios as control parameters, the system achieves both fast retrieval (high productivity) and accurate motion reconstruction (high precision)
Solution Approach 2:
The patent creates composite motion information by blending multiple pre-calculated sample motion data using blend ratios. This composite approach combines the advantages of multiple discrete calculations to produce accurate overall motion while maintaining the processing speed benefits of pre-computation

AI summary
[Problems] An appropriate motion expression in which a processing load on image processing for a motion of a character is reduced and a predetermined site of the character is in contact with a contact allowed object appropriately is carried out.[Means for solving the Problems] An image processing apparatus 100 generates motion information by blending plural kinds of sample motion information with an arbitrary blend ratio; detects, on the basis of the generated motion information, a reachable position P when a character C is operated; associates coordinate information indicating the detected reachable position P with the blend ratio; causes virtual spheres B, which are arranged within a range in which the reachable position P exists in the virtual space, to correspond to the reachable position P; outputs a virtual sphere according to a state of the character C in the virtual space on the basis of virtual sphere information; receives selection of a virtual sphere that is in contact with the contact allowed object; and controls an action of the character C on the basis of motion information corresponding to a blend ratio associated with the coordinate information indicating the reachable position P, which is caused to correspond to the virtual sphere for which the selection is received.
