Display Control Device for Motion Transition Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional motion transition images struggle to balance wide motion range and smooth expression, often resulting in either incomplete subject representation or inadequate temporal detail, due to limitations in clipping width and key frame arraying.
Innovation Solution
A display control device and method that allows dynamic playback and control of composited image data, enabling wider clipping widths for better subject coverage while maintaining smooth motion transitions through user-driven operations like dragging, flicking, and pointing on a touch panel, which adjusts frame positions and playback speeds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the clipping out width is widened to cover the entire motion range, then the subject coverage is improved, but the number of key frames that can be arrayed is reduced, resulting in insufficient motion transition expression
Solution Approach 1:
The patent transitions from a two-dimensional arraying problem to a three-dimensional solution by incorporating time as a third dimension. Instead of simply arraying key frames horizontally or vertically, the system creates a temporal sequence where key frames are displayed in chronological order, allowing both wide clipping width and sufficient frame count to coexist in the time dimension.
Solution Approach 2:
The patent applies dynamics by making the display configuration adaptable rather than fixed. The system dynamically adjusts the number of key frames to array, the clipping width, and the display timing based on the actual motion range and subject characteristics, allowing optimal balance between coverage area and transition detail for different scenarios.
2Loss of information
If the clipping out width is narrowed to increase the number of key frames, then the motion transition expression is improved, but the range of motion cannot be covered, resulting in missing subject portions
Solution Approach 1:
The patent resolves this contradiction by utilizing the time dimension to accommodate more key frames. Instead of competing for horizontal or vertical space, the system sequences key frames temporally, allowing narrow clipping widths to be compensated by increased temporal resolution, ensuring both complete subject coverage and fine motion transition expression.
Solution Approach 2:
The system dynamically determines the optimal clipping width based on the required number of key frames for adequate motion transition expression. The clipping width is not fixed but adapts to ensure the entire motion range is captured while maintaining sufficient temporal detail for form analysis.
3Manufacturing precision
If manual image manipulation is used to create motion transition images, then precise control over key frame selection is achieved, but the operation complexity and time consumption increase significantly
Solution Approach 1:
The patent implements self-service by enabling the system to automatically perform key frame selection, clipping width determination, and arraying configuration based on analyzing the motion characteristics of the subject. The device processes video data autonomously, identifying characteristic times and extracting key frames without requiring manual intervention, thus achieving both precision and operational simplicity.
Solution Approach 2:
The system performs preliminary analysis of the video data to pre-determine optimal key frame positions, clipping widths, and arraying parameters before actual image extraction. This preliminary action enables the system to automatically configure the best settings for capturing motion transitions, eliminating the need for manual trial-and-adjustment processes.

AI summary
The present invention relates to a display control device, a display control method, and a program, enabling realization of various playing display using frame images subjected to compositing processing as a motion transition image.A recording medium has recorded therein, as a series of recording frame image data, each of composited image data generated by sequentially performing image compositing processing for each input of frame image data, each of composited image data being enabled of moving image display in which a moving subject image in each frame image data is sequentially placed so as to be arrayed in a predetermined direction, with each recording frame image data being playable. In accordance with operation of an operation input unit such as a touch panel, a frame position to be played is determined out of the series of recording frame image data, and playing of the recording frame image data at the determined frame position is executed. Thus, a scene which the user desires to view out of the motion transition image can be easily viewed.
