Solution Overview

Problem

Current mobile terminals have limited input methods for controlling advanced camera functions, making it difficult for users to utilize camera features flexibly and intuitively, especially in response to changing situations.

Innovation Solution

A mobile terminal with a flexible display and a controller that allows users to control camera functions by receiving touch inputs moving from a start position to a reference position, enabling intuitive image capture based on distance and movement, which adjusts capture cycles, focus, and depth of field.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If fixed camera functions are provided in mobile terminals, then basic capture operations can be performed, but users cannot flexibly control camera functions according to changing situations

Engineering Contradiction:
Improveflexibility of camera function controlVSAvoidintuitiveness of control method
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent applies dynamics by making the camera function control movable and adjustable based on touch input position. The capture function is no longer fixed but dynamically changes based on where the user touches on the display, allowing flexible control while maintaining intuitive operation through direct touch interaction.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent introduces a spatial dimension to camera control by mapping touch position on the display (2D plane) to camera parameters. The distance from the center of the display becomes a new dimension for controlling capture behavior, transforming traditional single-point control into area-based contextual control.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If traditional touch input methods are used for camera control, then simple operations are possible, but advanced camera functions cannot be controlled intuitively

Engineering Contradiction:
Improvecontrol of advanced camera functionsVSAvoidcomplexity of control interface
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent makes the touch interface universal by enabling a single touch gesture to control multiple camera functions. The same touch input mechanism controls both basic capture and advanced functions like out-focus and continuous shooting, depending on the touch position, reducing the need for separate controls for each function.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system provides self-service by automatically determining which camera function to activate based on touch position without requiring users to manually select modes or configure settings. The camera controller interprets touch distance from center and automatically applies appropriate capture parameters.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If camera functions are provided in fixed forms, then device simplicity is maintained, but user convenience for sophisticated capture operations is reduced

Engineering Contradiction:
Improveuser convenience for capture operationsVSAvoideffectiveness of image capture
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The patent applies local quality by assigning different control functions to different regions of the touch display. The center region corresponds to normal capture, while regions farther from the center trigger out-focus or continuous shooting modes, allowing users to access sophisticated capture operations conveniently based on where they touch.

Inventive Principle:
Principle #3Local quality

AI summary

Provided is a mobile terminal including a camera, a display, and a controller. The controller is configured to display, on the display, an image identified by the camera, receive a touch input moving from a start position on the display, and capture the image, identified by the camera, based on a distance from a reference location to a position of the touch input.
