Moving Image Processing Apparatus for Dynamic Frame Rate Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional moving image capturing technologies cannot adjust frame rates in real-time during capturing, limiting the ability to change reproduction speed of captured images.
Innovation Solution
A moving image processing apparatus and method that generates speed control data based on user input during capturing, allowing for adjustment of reproduction speed by modifying frame rate, play count, or removing frames, and synchronizing audio data output accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If frame rate is set during capturing, then moving image can be captured at desired speed, but frame rate cannot be changed after capturing
Solution Approach 1:
The system generates speed control data during the capturing process itself, rather than requiring post-processing. This preliminary action allows the frame rate to be predetermined and stored with the image data, enabling future adjustment without re-capturing or complex reprocessing.
Solution Approach 2:
The patent introduces dynamic adjustment capability by storing speed control data that allows the frame rate to be changed from static (fixed during capture) to dynamic (adjustable during playback). This enables the same captured data to adapt to different reproduction speeds without recapturing.
2Speed
If reproduction speed is adjusted by changing frame rate, then playback speed can be modified, but audio synchronization may be affected
Solution Approach 1:
The system segments the moving image into multiple frames with associated speed control data. By processing frames individually based on their stored speed information, the system can adjust reproduction speed while maintaining audio synchronization through precise frame-level control.
Solution Approach 2:
The patent uses speed control data as feedback information stored with the image data. This feedback mechanism allows the reproduction device to adjust frame rates while maintaining synchronization by referencing the original speed control parameters embedded in the data.
3Duration of action of moving object
If frames are removed or duplicated to adjust reproduction time, then playback duration can be changed, but image quality may be affected
Solution Approach 1:
Instead of physically removing or duplicating frames (which affects image quality), the system changes the playback parameter by adjusting the reproduction speed based on stored speed control data. This parameter-based approach maintains original image quality while achieving desired reproduction time adjustments.

AI summary
Provided is a non-transitory computer readable medium including computer readable instruction, which when executed by a computer processor cause the computer to read image data extracted from a moving image file stored in the storage medium, a frame rate of the image data, and speed control data of the image data, determine a reproduction speed of a first section of the moving image file by analyzing the speed control data, calculate a change rate of the first section based on the reproduction speed of the first section; and reproduce the moving image file by increasing a reproduction time or removing some of a plurality of frames included in the first section based on the calculated change rate.
