Solution Overview

Problem

Current mobile terminals lack efficient methods for capturing images using multiple cameras with different angles of view, limiting their functionality in capturing and displaying images from various perspectives.

Innovation Solution

A mobile terminal equipped with at least two cameras, one configured to capture images at a standard angle and the other at a wider angle, with a controller that allows users to switch between them based on user requests, enabling simultaneous or sequential image capture and display of images from both cameras.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple cameras with different angles of view are equipped, then imaging versatility is improved, but device complexity increases

Engineering Contradiction:
Improveimaging versatilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The mobile terminal is equipped with multiple cameras (wide-angle camera and standard camera) that can be selectively used based on different imaging needs. The controller automatically selects the appropriate camera based on the captured image content, enabling the system to perform multiple imaging functions (wide-angle shots, standard shots, panoramic images) with a unified device structure.

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

2Measurement precision

If manual camera switching is implemented, then imaging precision is improved, but ease of operation deteriorates

Engineering Contradiction:
Improveimaging precisionVSAvoidease of operation
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The controller automatically determines which camera to use by analyzing the captured image content without requiring manual user input. The system self-activates the appropriate camera (wide-angle or standard) based on whether the captured scene benefits from a wider field of view or standard perspective, eliminating the need for users to manually switch cameras while maintaining optimal imaging precision.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The controller continuously monitors the captured image content and uses this feedback to automatically select the most appropriate camera. By analyzing the image data in real-time, the system adjusts camera selection dynamically, ensuring the best imaging results without requiring user intervention.

Inventive Principle:
Principle #23Feedback

AI summary

A mobile terminal including a first camera on a front surface of the mobile terminal and configured to capture images at a first angle of view; a second camera on the front surface of the mobile terminal and configured to capture images at a second angle of view different from the first angle of view; a display; and a controller configured to display at least a first image with the first angle of view from the first camera, and display a second image with the second angle of view from the second camera, in response to a request to obtain the second image from the second camera instead of obtaining the first image from the first camera.
