Scroll Screen Camera Control for Flexible Zoom Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional photographing parameter adjustment methods in electronic devices are inflexible and unable to adapt to the continuous changes in screen hardware, leading to inefficient and less enjoyable photographing experiences.
Innovation Solution
A photographing method and apparatus that utilize a scroll screen to adjust photographing parameters, such as zoom ratio, by determining unfolding parameters based on user inputs, allowing direct and flexible adjustment of parameters like zoom ratio without needing traditional controls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional photographing parameter adjustment methods are used, then the device structure remains simple, but the adaptability to screen hardware changes and user control flexibility deteriorates
Solution Approach 1:
The scroll screen is designed to serve multiple functions: it acts as both the display interface and the control input mechanism for photographing parameters. By making the screen itself adjustable and responsive to user interactions (scrolling, touching, clicking), it eliminates the need for separate control buttons or dials, thereby improving adaptability without significantly increasing overall device complexity
Solution Approach 2:
The scroll screen introduces dynamic adjustability to the photographing parameters. Instead of fixed parameters or static controls, the system allows real-time dynamic adjustment of zoom ratio, focus, exposure, and other parameters through continuous scrolling motions, enabling the device to adapt flexibly to user needs and screen hardware changes
2Ease of operation
If traditional parameter controls are used, then the device complexity is low, but the ease of operation and adjustment precision deteriorates
Solution Approach 1:
The control interface for photographing parameters is merged with the display screen itself. The scroll screen combines the visual feedback function with the input control function, allowing users to interact directly with the parameter display area to adjust settings. This integration simplifies the user experience by eliminating the need to locate and operate separate control elements
Solution Approach 2:
The scroll screen acts as an intermediary between the user and the photographing parameters. Through scrolling animations and visual feedback displayed on the screen, the system provides intuitive mediation that guides users in adjusting parameters precisely without requiring understanding of complex technical settings or multiple control steps
3Productivity
If fixed photographing parameters are used, then the device complexity is low, but the productivity and photographing efficiency deteriorates
Solution Approach 1:
The system prepares multiple preset photographing parameter configurations that can be quickly accessed and adjusted through simple scroll interactions. Common photographing scenarios (portrait, landscape, macro, night mode) have pre-configured parameter sets that can be selected and fine-tuned rapidly, eliminating the need to manually adjust each parameter from scratch and thereby improving photographing efficiency
Solution Approach 2:
The scroll screen provides real-time visual feedback during parameter adjustment, showing users how changes in zoom ratio, exposure, or other parameters will affect the final photograph. This immediate feedback loop allows users to make informed adjustments quickly and accurately, reducing trial-and-error time and improving overall photographing productivity

AI summary
A photographing method includes receiving a first input performed by a user to the scroll screen; in response to the first input, obtaining a photographing parameter based on an unfolding parameter of the scroll screen, where the unfolding parameter is determined based on the first input; and performing photographing based on the photographing parameter, to obtain a target file, where the target file includes at least one of the following: an image or a video.
