Mobile Terminal Multi-Focusing Guide Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile terminals lack an efficient and convenient method for controlling cameras using touch screens, making it difficult for users to focus and capture images effectively.
Innovation Solution
A mobile terminal equipped with a camera and touch screen, where a controller displays a preview image and adjusts the focusing area based on user input, allowing for manual focusing and multi-focusing by varying the size and position of a guide on the touch screen, enabling precise image capture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a touch screen is used to control camera focusing, then ease of operation is improved, but device complexity increases
Solution Approach 1:
A guide indicator is introduced as an intermediary element between the touch screen interface and the camera focusing mechanism. The guide visually represents the focusing area and responds to touch inputs, mediating the interaction between user input and camera control without requiring complex direct mapping algorithms
Solution Approach 2:
Traditional mechanical camera control interfaces (physical buttons, dials) are replaced with a touch screen interface that uses software-based guide indicators to control focusing. This substitution enables more intuitive gesture-based control while reducing mechanical components
2Adaptability or versatility
If multi-focusing on multiple points is implemented, then adaptability is improved, but device complexity increases
Solution Approach 1:
The focusing functionality is segmented to allow independent focus points on the touch screen. Each touched location creates an independent guide indicator representing a separate focusing area, enabling multiple objects at different distances to be focused simultaneously without requiring a monolithic focusing system
Solution Approach 2:
The focusing system becomes dynamic by allowing users to add, remove, and reposition focus points during the photographing process. The guide indicators and their corresponding focusing areas can be modified in real-time based on user interaction, providing flexible adaptation to different scene requirements
3Measurement precision
If the focusing area is adjusted by varying guide size, then measurement precision is improved, but ease of operation deteriorates
Solution Approach 1:
The guide indicator provides visual feedback about the current focusing area size and position. As users interact with the touch screen, the guide dynamically adjusts its size and position, giving immediate visual confirmation of the focusing parameters without requiring users to manually configure complex settings
