Multi-Camera Preview Switching With Opacity and Blur Transitions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The switching between different photographing modes in electronic devices with multiple cameras results in a rigid and 'frame freezing' visual effect on the photographing preview interface, affecting user experience due to delays in displaying picture data from different cameras.
Innovation Solution
A video shooting method that includes animation processing during mode switching, transitioning between displayed images using opacity and Gaussian blur changes to create a fluent and vivid picture switching experience.

Engineering Contradiction Analysis
1Speed
If picture data from different cameras is directly displayed during mode switching, then the switching speed is fast, but the visual effect becomes rigid with frame freezing
Solution Approach 1:
The patent applies dynamics by transitioning from static direct display to dynamic animation processing. During mode switching, the system dynamically adjusts opacity values and applies Gaussian blur effects that change over time, creating a smooth transition animation that eliminates rigid frame freezing while maintaining fast switching capability
Solution Approach 2:
The patent changes display parameters (opacity and blur) during the switching process. The first image's opacity transitions from transparent to opaque, and Gaussian blur values are dynamically adjusted, transforming the abrupt parameter change into a smooth visual transition that improves fluency without sacrificing switching speed
2Ease of operation
If transition animation is added during picture switching, then visual fluency is improved, but the processing complexity increases
Solution Approach 1:
The patent segments the transition process into distinct phases: initial state with first image transparent, transition phase with opacity adjustment and blur effects, and final state with first image opaque. This segmentation allows complex animation to be managed through discrete, controllable steps that reduce overall processing complexity
Solution Approach 2:
The patent performs preliminary actions by pre-defining the animation parameters (opacity transition curves, Gaussian blur values) before execution. This preparation allows the actual switching to proceed smoothly without real-time complex calculations, reducing processing burden during the critical switching moment

AI summary
A video shooting method and an electronic device. The method includes: displaying, in a first region of a display, a first image collected in real time by a first camera, and displaying, in a second region of the display, a second image collected in real time by a second camera, where the second region is the entire display region of the display, and the first region is smaller than the second region; gradually decreasing an opacity of the first image displayed in the first region from a second opacity to a first opacity in response to detecting a user operation; and displaying a third image in a third region of the display, where the third image is the second image collected in real time by the second camera, and the third region of the display is the entire display region of the display.
