Video Focus Tracking for Synchronized Audio Zoom
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video recording technologies require manual adjustment of zoom magnification for simultaneous audio and image zooming, necessitating good shooting skills to achieve high-quality videos, and fail to enhance user sensory experience effectively.
Innovation Solution
A video processing method that implements simultaneous focus tracking of audio and image by determining a focus region, enhancing sound of the target object while suppressing other sounds, and displaying images in a 'picture-in-picture' form to improve user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual zoom magnification adjustment is used for simultaneous audio and image zooming, then the terminal can achieve zoomed video recording, but the operation becomes complex and requires good shooting skills
Solution Approach 1:
The terminal automatically determines the focus region and adjusts zoom magnification without requiring manual user operation. The system self-identifies the target object and autonomously controls the imaging and audio processing to achieve simultaneous zooming, eliminating the need for users to manually adjust zoom magnification while maintaining the capability for high-quality zoomed video recording
2Ease of manufacture
If zoom magnification is increased to make the photographed object larger in the video, then the sensory experience is enhanced, but the user needs to have good shooting skills to maintain audio-image correspondence
Solution Approach 1:
The system continuously monitors the focus region and dynamically adjusts both image and audio processing based on real-time feedback. When the focus region is determined, the terminal automatically adjusts the imaging parameters and audio processing parameters to maintain correspondence between the visual zoomed effect and the audio focus, ensuring that the photographed object remains the primary focus in both video and audio without requiring manual intervention
Solution Approach 2:
The terminal automatically changes multiple parameters including zoom magnification, audio processing parameters, and focus tracking parameters based on the determined focus region. The system adjusts these parameters in a coordinated manner to achieve simultaneous audio-image zooming with enhanced sensory experience, eliminating the need for users to manually coordinate multiple parameter adjustments

AI summary
A video processing method and a terminal are provided. In the method, when the terminal records a video, the terminal may shoot (acquire) an image by using a camera (the image shot by using the camera is referred to as an original image below), and determine a focus of the shooting based on the original image. Then, the terminal may implement image focus tracking on a photographed object displayed in a first image region in which the focus is located, and implement audio focus tracking on a photographed object displayed in a second image region in which the focus is located. A focus tracking video is obtained through the image focus tracking and the audio focus tracking.
