Solution Overview

Problem

Existing intelligent terminals face challenges in meeting the increasing photography needs of users, particularly in providing enhanced features like 4K HDR mode and AI automatic scenario identification to create a cinematic experience during movie shooting.

Innovation Solution

Implementing a 4K HDR mode and AI automatic scenario identification in the camera of an electronic device, which automatically identifies the shooting scenario and recommends an LUT template to match the scenario, allowing for cinematic image adjustments and multiple shooting options like slow motion and time-lapse.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If AI automatic scenario identification and LUT template recommendation are implemented, then the cinematic quality and user experience of movie shooting are improved, but the device complexity and processing load increase

Engineering Contradiction:
Improvecinematic qualityVSAvoiddevice complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The system pre-prepares multiple LUT templates in advance corresponding to different shooting scenarios (portrait, landscape, night, etc.). When scenario identification is performed, the matching LUT template is directly applied without real-time complex computation, thus improving cinematic quality while controlling device complexity

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system changes image parameters by applying predefined LUT templates that adjust color values, contrast, and other cinematic parameters. This approach achieves high-quality cinematic effects through parameter transformation rather than complex real-time processing

Inventive Principle:
Principle #35Parameter changes

2Manufacturing precision

If 4K HDR mode is enabled to increase preview image resolution, then the picture quality is improved, but the energy consumption and processing load increase

Engineering Contradiction:
Improvepicture qualityVSAvoidenergy consumption
Core Design Contradiction:
Manufacturing precisionVSUse of energy by moving object

Solution Approach 1:

The system applies 4K HDR processing selectively based on the identified shooting scenario. For scenarios where high quality is critical (e.g., portrait, landscape), 4K HDR is enabled; for other scenarios, standard resolution is used. This partial application reduces overall energy consumption while maintaining picture quality where needed

Inventive Principle:
Principle #16Partial or excessive action

3Adaptability or versatility

If multiple movie shooting functions (slow motion, time-lapse, 4K HDR) are provided, then the adaptability and user satisfaction are improved, but the device complexity and operation difficulty increase

Engineering Contradiction:
ImproveadaptabilityVSAvoidease of operation
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system automatically identifies the shooting scenario and selects the most appropriate LUT template and shooting parameters without requiring manual user configuration. Users simply need to capture the scene, and the system handles the complex parameter adjustments automatically, thus improving ease of operation while maintaining high adaptability

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system integrates multiple movie shooting functions (slow motion, time-lapse, 4K HDR, LUT templates) into a unified movie mode interface. A single movie mode entry provides access to all these features, reducing operational complexity while maintaining versatility through unified multi-functional design

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

AI summary

This application provides a photographing method and an electronic device. The method includes: after a user operation is received to enable a movie shooting mode, identifying a photographing scenario based on a collected preview image, and recommending a target LUT template that matches the photographing scenario; and when a third operation performed by a user on a movie shutter control is received, shooting and generating a target video based on the target LUT template, so that a highquality movie video is shot.
