Light Trail Shooting Preview Control With Real-Time Parameter Tuning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The shooting form in the light stream shutter mode is fixed, failing to meet user requirements due to a fixed light trail generation parameter.
Innovation Solution
A method and apparatus that allow users to adjust light trail generation parameters through user inputs on controls during the shooting process, enabling dynamic adjustment of light trail quantity and speed, and updating the video preview in real-time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed light trail generation parameter is used in the light stream shutter mode, then the shooting process is simple and stable, but the shooting form becomes single and cannot meet diverse user requirements
Solution Approach 1:
The patent implements dynamic adjustment of light trail generation parameters during the shooting process. The electronic device allows users to modify parameters such as light trail quantity and speed in real-time through a user interface, transforming the previously static shooting mode into a dynamic one that adapts to user preferences without requiring mode switching or complex reconfiguration
Solution Approach 2:
The patent directly applies parameter changes by enabling users to adjust specific light trail generation parameters (such as quantity, speed, and distribution) during video shooting. This allows the system to transition from a fixed-parameter mode to a variable-parameter mode, creating diverse shooting forms while maintaining operational simplicity through intuitive controls
2Ease of operation
If real-time updates of video preview are implemented during shooting, then user feedback and control are improved, but system resource consumption and processing complexity increase
Solution Approach 1:
The patent implements partial real-time updates of the video preview rather than complete frame-by-frame rendering. The system updates only the portions of the preview that reflect current parameter adjustments, reducing unnecessary processing while maintaining sufficient visual feedback for user control during the shooting process

AI summary
A shooting control method and apparatus, and an electronic device are provided. The method includes: displaying a first interface in a process of shooting a target video, where the target video is a video of a light trail generation process, and the first interface includes a video preview window and at least one first control; receiving a first input performed by a user on a first target control, where the first target control is a control in the at least one first control; and adjusting a light trail generation parameter corresponding to the first target control in response to the first input, and updating an image in the video preview window based on the adjusted light trail generation parameter.
