Solution Overview

Problem

Mobile terminals with multiple cameras lack an effective user interface for inputting camera control commands and are unable to generate new images from photographs taken by multiple cameras.

Innovation Solution

A mobile terminal system that includes a controller to set and apply distinct photographing conditions for each camera, synthesize images captured by multiple cameras, and display the resulting combined image, enabling effective camera control and image generation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a mobile terminal is equipped with multiple cameras to capture images from different directions or angles, then the image capturing capability and versatility are improved, but the device complexity and control interface difficulty increase

Engineering Contradiction:
Improveimage capturing capabilityVSAvoidcontrol interface difficulty
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The control interface is segmented into separate control regions, with each region corresponding to a specific camera. When a user interacts with a particular region, only the associated camera is activated or controlled, simplifying the user's decision-making process and reducing the perceived complexity despite having multiple cameras.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A controller serves as an intermediary between the user interface and multiple cameras. The controller receives user inputs, determines which camera should be activated based on the input region or pattern, and transmits appropriate control signals to the selected camera, thereby managing the complexity of multi-camera coordination.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If multiple cameras are used to photograph images simultaneously or sequentially, then the productivity and image synthesis capability are improved, but the difficulty of detecting and measuring photographing conditions increases

Engineering Contradiction:
Improveimage synthesis capabilityVSAvoidphotographing condition control
Core Design Contradiction:
ProductivityVSDifficulty of detecting and measuring

Solution Approach 1:

The system provides feedback to the user about the current photographing conditions and camera selection status. This may include visual indicators showing which camera is active, preview images from selected cameras, or status information about synthesis progress, making it easier for users to understand and control the multi-camera photographing process.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The controller automatically manages the complexity of coordinating multiple cameras by implementing self-service functionality. It autonomously selects which cameras to activate based on predefined rules or user preferences, automatically adjusts photographing conditions, and handles the image synthesis process without requiring users to manually configure each parameter.

Inventive Principle:
Principle #25Self-service

3Manufacturing precision

If distinct photographing conditions are set for each camera, then the manufacturing precision and image quality are improved, but the ease of operation decreases

Engineering Contradiction:
Improveimage qualityVSAvoidcamera control convenience
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The photographing conditions are made dynamic rather than static. The controller automatically adjusts parameters such as exposure, focus, and shutter speed for each camera based on real-time conditions detected by sensors or previously captured images, eliminating the need for users to manually set and adjust each parameter while maintaining high image quality.

Inventive Principle:
Principle #15Dynamics
