Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single camera is used for imaging, then the device structure is simple, but the imaging mode is single and lacks flexibility

Engineering Contradiction:
Improveimaging mode flexibilityVSAvoidcamera system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The imaging system is segmented into multiple independent camera modules, each with different focusing ranges (first camera for distant objects, second camera for close-up objects). This segmentation allows the system to capture diverse imaging modes simultaneously while maintaining manageable individual camera structures.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The camera system is designed with multi-functionality by equipping the device with multiple cameras that can perform different imaging tasks. The first camera handles distant object imaging while the second camera handles close-up imaging, making the overall system universal and adaptable to various photography scenarios.

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

2Adaptability or versatility

If multiple cameras with different focusing ranges are used, then imaging flexibility is improved, but the device complexity increases

Engineering Contradiction:
Improvefocusing range adaptabilityVSAvoidmulti-camera system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system dynamically switches between different camera modules based on the imaging requirements. The processing unit automatically determines which camera (first or second) should be activated based on the object distance and imaging mode, making the system adaptable without requiring manual configuration.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes operational parameters by switching between different camera modules with different focusing ranges. By adjusting which camera module is active based on the imaging scenario (distant vs. close-up), the system achieves parameter variability without physical reconfiguration.

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If images are processed from multiple cameras, then the display state customization is enhanced, but the image processing complexity increases

Engineering Contradiction:
Improvedisplay state adjustabilityVSAvoidimage processing complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system performs preliminary action by capturing images from multiple cameras simultaneously before processing. This allows the processing unit to have multiple image sources ready for various display state configurations, making subsequent image composition and display customization more efficient.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system creates copies of image data from different camera modules and processes them independently. The processing unit can generate multiple versions of the same scene with different display states by copying and transforming the captured image data, reducing the need for complex real-time processing.

Inventive Principle:
Principle #26Copying

AI summary

This application relates to the technical field of communications, and provides a photographing method and apparatus, an electronic device and a readable storage medium. The method includes: receiving a first input performed by a user, the first input being used for adjusting the display state of a first object in a first preview image, and the first preview image being an image captured by a first camera; in response to the first input, displaying a second preview image, the second preview image being obtained by processing an image captured by a main camera, and the second preview image including the first object whose display state has changed; and performing, according to display information of the second preview image, image processing on N images captured by N cameras to obtain a first target image, where the N cameras at least include the main camera, and N is a positive integer.
