Solution Overview
Problem
Existing mobile terminals face challenges in efficiently and conveniently controlling cameras for image capture, particularly on touch screens, which limits user experience and functionality in capturing desired images.
Innovation Solution
A mobile terminal with a touch screen that utilizes a proximity sensor and touch controller to enable intuitive image capture through auto focusing and image capturing commands via touch inputs, allowing users to select focus points and capture images easily without complex menu navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional camera control methods are used on mobile terminals, then the camera can be controlled, but the operation becomes complex and inconvenient requiring menu navigation
Solution Approach 1:
The touch screen serves as an intermediary between the user and the camera system. By displaying a visual preview image on the touch screen and allowing direct touch interaction with the image, the system eliminates the need for complex menu navigation. The touch screen translates user touch gestures directly into camera control commands, simplifying the operation while maintaining full camera functionality.
Solution Approach 2:
The patent replaces traditional mechanical camera control interfaces (physical buttons, dials, and menu systems) with a touch-based graphical interface. Users interact with the camera by touching the preview image displayed on the touch screen, which substitutes the mechanical interaction paradigm with a more intuitive visual and tactile interface, greatly improving ease of operation.
2Ease of operation
If touch screen interface is used for camera control, then operation becomes more intuitive, but the precision of focus control may be reduced
Solution Approach 1:
The system provides visual feedback by displaying the preview image on the touch screen and showing indicators for focus areas. When a user touches a specific region of the preview image, the system provides feedback by adjusting the focus to that region and updating the display accordingly. This feedback loop allows users to iteratively refine their focus selection, maintaining precision while preserving the intuitiveness of touch-based interaction.
