Split-Screen Video Aspect Ratio Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When recording a video on a mobile device, the proportions of the displayed reference video and recorded video often differ, leading to discordant displays, which can be uncomfortable for human eyes and affect the overall viewing experience in split-screen applications.
Innovation Solution
A method and apparatus that compare the height-width ratio of the reference video to a preset optimal ratio, adjusting the picture size of the reference video based on the comparison result and the size of the recorded video to ensure visually coordinated and comfortable display in split-screen mode, using equal-ratio scaling and clipping techniques to maintain display quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the reference video and recorded video are displayed in split-screen mode with different proportions, then both videos can be displayed simultaneously, but the display becomes discordant and uncomfortable for human eyes
Solution Approach 1:
The patent changes the display parameters (width and height) of video pictures dynamically. It compares the aspect ratios of reference video and recorded video, then adjusts the display dimensions of one or both videos to achieve consistent proportions. This parameter adjustment resolves the visual discomfort caused by discordant proportions while maintaining split-screen display functionality.
2Object-affected harmful factors
If the picture size of reference video is adjusted to match the recorded video, then visual coordination is improved, but the original aspect ratio may be distorted
Solution Approach 1:
The patent applies different processing strategies to different scenarios. When aspect ratio adjustment is needed, it either adjusts the display size of the reference video to match the recorded video, or clips the recorded video to match the reference video, or adds black bars. This localized quality adjustment ensures that the overall visual coordination is improved while minimizing distortion through appropriate local modifications.

AI summary
Provided are a video picture adjustment method and apparatus, a computer device and a storage medium. The method includes the following steps: a first height-width ratio of a picture of a reference video is compared with a preset height-width ratio to obtain a first comparison result, where a human-eye comfort parameter corresponding to the preset height-width ratio meets a preset condition; and a picture size of the reference video is adjusted according to a picture size of the recorded video and the first comparison result, where the reference video and the recorded video are two views displayed on a display screen in a split-screen manner.
