Foldable Device Preview Duplication for Collaborative Photography
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for displaying a preview image on electronic devices with foldable displays are monotonous, limiting the ability for multiple users to simultaneously view the image during photography.
Innovation Solution
A method and apparatus for displaying a preview image on both the first and second displays of a foldable electronic device, where the second display is lit up when a collaboration condition is triggered, allowing the same preview image to be shown on both displays, enhancing user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the preview image is displayed only on the front display, then the device complexity is reduced, but the adaptability for multiple users to view simultaneously is limited
Solution Approach 1:
The patent copies the first framing content from the front display to the second display, creating a duplicate preview image that can be viewed simultaneously by multiple users on different sides of the device, thereby resolving the contradiction between display adaptability and system complexity
Solution Approach 2:
The patent segments the display system into independent front and back displays, each capable of showing the preview image separately, allowing multiple users to view simultaneously without requiring complex coordinated control between displays
2Ease of operation
If the second display is lit up for collaboration, then the ease of operation for coordinated photography is improved, but the energy consumption increases
Solution Approach 1:
The patent dynamically controls the second display's power state, lighting it up only when a collaboration condition is triggered and keeping it off otherwise, thereby providing coordinated photography capability when needed while minimizing energy consumption during normal operation

AI summary
A method and an apparatus for displaying a preview image, and a readable storage medium. The method includes: enabling a camera in response to detecting a camera enabling operation; displaying a first preview image on a first display, where the first preview image is generated based on a first framing content collected by the camera; lighting up a second display when a collaboration condition is triggered, where the collaboration condition is a condition of synchronously displaying the first preview image on the second display; copying the first framing content to obtain a second framing content; generating a second preview image based on the second framing content; and displaying the second preview image on the second display.
