Mobile Terminal Camera Interface Segmentation and Touch Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminals have limited and inconvenient camera interfaces, which hinder user experience in image capturing due to restricted functionality and interface design.
Innovation Solution
A mobile terminal with a wireless communication unit, camera, and display unit that allows users to switch between states with or without graphic objects related to image capturing, enabling touch-based control for capturing images, thereby simplifying the image capturing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If graphic objects are displayed overlapping the preview image to provide camera control functions, then the camera functionality is accessible, but the preview image interface becomes cluttered and user experience deteriorates
Solution Approach 1:
The display screen is segmented into multiple touch-sensitive regions: a first region for displaying the preview image and a second region for displaying graphic objects related to image capturing functions. This spatial segmentation allows both the clean preview display and accessible camera controls to coexist without overlapping, resolving the contradiction between interface cleanliness and control accessibility.
2Adaptability or versatility
If graphic objects are displayed on the preview image to enable camera functions, then camera control is provided, but the interface complexity increases
Solution Approach 1:
The interface design transitions from a two-dimensional overlapping layout to a multi-regional spatial distribution. Graphic objects are placed in a separate second region adjacent to the preview image region, creating a multi-dimensional interface structure that maintains functional versatility while reducing visual complexity and improving user experience.
3Adaptability or versatility
If the camera interface includes traditional graphic objects for control, then image capturing functions are available, but the user experience is inconvenient and limited
Solution Approach 1:
The touch-sensitive display screen serves multiple functions: it displays the preview image in the first region, presents camera control graphic objects in the second region, and responds to touch inputs from users. This multi-functional design integrates both information display and control operations into a single unified interface, enhancing user convenience while maintaining full camera functionality.

AI summary
A mobile terminal including a wireless communication unit configured to perform wireless communication; a camera configured to obtain an image; a display unit configured to display a preview image obtained through the camera; and a controller configured to control the display unit to operate in any one of a first state in which a graphic object relating to an image capturing function is displayed overlapping the preview image and a second state in which the graphic object is not displayed while the preview image is displayed, based on a user request, and when a first pre-set type of touch is sensed in a region on which the preview image is displayed in the second state, control the camera to capture the preview image based on the pre-set type of touch.
