Foldable-Screen Video Frame Marking With Progress Indicators
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users find it difficult to quickly mark and locate video frames of interest during video editing on electronic devices with foldable screens, especially when the screens are in an unfolded state, which limits efficient video processing.
Innovation Solution
An image processing method that allows users to mark video frames of interest by performing a preset operation, such as a single click or long press, which sets a specified mark on the frame, and displays this mark on a progress bar, enabling easy identification and editing of these frames.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If video frames are displayed on a foldable screen in unfolded state, then the display area is increased, but it becomes difficult to quickly mark and locate video frames of interest
Solution Approach 1:
The patent divides the video editing interface into multiple functional regions: a video playback area, a progress bar area with mark indicators, and a control area. This segmentation allows the system to maintain a large unfolded display area while organizing marking and location functions in specific accessible zones, resolving the contradiction between large display area and ease of operation.
Solution Approach 2:
The patent introduces a progress bar with visual mark indicators as an intermediary element between the video content and the marking operation. Users can quickly locate and mark video frames by interacting with the progress bar indicators rather than directly manipulating video frames, which simplifies the marking process on large foldable screens while maintaining comprehensive display area.
2Device complexity
If traditional video marking methods are used on foldable screens, then the device structure is simple, but video processing efficiency is reduced
Solution Approach 1:
The patent implements preliminary action by automatically generating and displaying mark indicators on the progress bar before the user performs marking operations. The system pre-configures the interface with clickable mark indicators that correspond to specific video frames, allowing users to quickly locate and mark frames of interest without manual searching, thereby improving video processing efficiency while maintaining simple device structure.
Solution Approach 2:
The patent uses visual color changes and distinct visual indicators on the progress bar to highlight markable video frames. Different colors or visual states indicate different frame statuses (e.g., marked vs. unmarked, key frames vs. regular frames), enabling users to quickly identify and locate video frames of interest at a glance, thus improving processing efficiency without adding device complexity.

AI summary
An image processing method is performed by an electronic device. The method includes: receiving a first preset operation configured to mark at least one of a plurality of video frames in a case that the plurality of video frames are displayed on a screen of the electronic device; after receiving the first preset operation, determining a target video frame corresponding to the first preset operation; setting a specified mark for the target video frame.
