Image Processing Apparatus Subject Movement Data Creation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing technologies cannot effectively express the movement of a subject in still images derived from moving images, as they only display a portion cut from the whole still image, failing to capture the subject's movement due to position changes.
Innovation Solution
An image processing apparatus that detects subject movement in partitioned blocks of a screen area, creates subject movement data, and processes still images to move corresponding blocks based on this data, allowing the movement of the subject to be expressed in the still images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a still image is displayed as a whole, then the image data volume is reduced, but the movement of the subject cannot be expressed
Solution Approach 1:
The still image is divided into multiple blocks, and movement information is selectively applied to specific blocks containing the subject. This allows the system to maintain a compact overall image structure while incorporating movement data only where necessary, thus reducing total data volume while preserving subject movement information.
Solution Approach 2:
Different blocks of the still image are treated differently based on their content. Blocks containing the subject are assigned movement information to enable subject movement expression, while other blocks remain static. This local differentiation allows movement information to be preserved for the subject without requiring movement data for the entire image.
2Loss of information
If moving image data is used to express subject movement, then subject movement can be expressed, but the data volume becomes large
Solution Approach 1:
The invention extracts only the essential movement information from moving image data and applies it selectively to specific blocks containing the subject. Instead of using complete moving image sequences, only the necessary movement vectors or displacement data are extracted and stored, dramatically reducing data volume while maintaining the ability to express subject movement.
Solution Approach 2:
The system applies movement information partially - only to blocks containing the subject rather than the entire image. This partial application of movement data achieves the goal of expressing subject movement without the excessive data requirements of complete moving image sequences.
3Measurement precision
If a portion cut from still image is overlaid and displayed, then the subject position can be tracked, but the movement of the subject itself cannot be expressed
Solution Approach 1:
The invention transforms static block images into dynamic elements by applying movement information. Blocks containing the subject are animated based on extracted movement data, allowing the subject to move within the still image context. This dynamic treatment of selected blocks enables both position tracking and subject movement expression simultaneously.
Solution Approach 2:
By segmenting the image into blocks and selectively animating only those containing the subject, the system maintains precise position tracking capability while adding movement expression. The segmentation allows independent treatment of subject-containing blocks versus other static blocks.
Data Source
AI summary
The image processing apparatus is provided with a subject movement data creation unit that detects the movement of subjects in a plurality of partitioned blocks that partition a screen area of moving images, and creates subject movement data that specifies a partitioned block where there is movement in the subject and the movement of the subject in that partitioned block; a still image acquisition unit that acquires still images; and a still image processor that causes the image of the still image blocks corresponding to the partitioned blocks specified by the subject movement data to move in accordance with the movement of the subject specified by the subject movement data, on the still image acquired by the still image acquisition unit using the subject movement data created by the subject movement data creation unit.
