Video Speed-Change Recording Triggered by Target State Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video recording technologies require complicated operating steps and procedures for creating slow-motion or fast-motion videos, which negatively impact user experience by not providing convenient operations.
Innovation Solution
A method and apparatus that allows for speed change recording by recognizing a target state in a captured video image, playing audio at a changing speed according to a first speed change mode, and playing video images at constant or changing speeds based on opposite speed change modes, enabling direct speed change recording without the need for video editing software.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If video speed change is achieved by importing captured video into video editing software for slow playback or fast playback processing, then the video speed change effect is achieved, but the operating steps and processing procedures become complicated
Solution Approach 1:
The patent applies preliminary action by performing speed change processing on the video during the capture process itself, rather than requiring post-processing in video editing software. The processing unit changes the playback speed of the captured video in real-time or during the recording process, so that when the video is later played back, it already has the desired slow-motion or fast-motion effect without needing additional editing steps.
Solution Approach 2:
The patent merges the video capture function with the speed change processing function into a single integrated system. The processing unit is incorporated within the video recording device, combining the camera's capture capability with real-time or post-capture speed adjustment capabilities, thereby eliminating the need for separate video editing software and simplifying the overall workflow.
2Productivity
If frame insertion is used to improve video recording frame rate for slow action videos, then the video recording frame rate can exceed the maximum frame rate supported by the image sensor hardware, but the device complexity increases
Solution Approach 1:
The patent applies dynamics by enabling the video recording system to adaptively adjust the playback speed based on the captured content. The processing unit dynamically changes the speed at which the captured video frames are played back, allowing the system to achieve high frame rates for slow-action sequences without requiring the hardware to continuously operate at maximum capacity. This dynamic speed adjustment provides flexibility in capturing different types of motion at appropriate frame rates.
