Solution Overview

Problem

Existing electronic devices with multiple cameras struggle to effectively utilize different camera configurations for improved image and video shooting, particularly in terms of focal length coverage and image quality.

Innovation Solution

A method for image or video shooting that utilizes multiple cameras, including a first and a second camera, where operations on widgets determine zoom ratios and lightness settings to capture and process images, allowing for cooperative processing to enhance image quality and achieve full focal length coverage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple cameras are equipped in the electronic device, then more image shooting and video shooting manners can be provided, but the device complexity increases

Engineering Contradiction:
Improveshooting mannersVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements multi-functionality by enabling different camera combinations (main camera + auxiliary camera) to serve multiple shooting modes (wide-angle, normal, telephoto). The system dynamically selects and combines cameras based on focal length requirements, allowing a single auxiliary camera to participate in multiple shooting scenarios rather than requiring dedicated cameras for each mode.

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

Solution Approach 2:

The patent segments the focal length range into different zones (wide-angle, normal, telephoto) and assigns different camera combinations to each zone. The main camera handles the normal range while the auxiliary camera supplements the wide-angle and telephoto ranges, creating a segmented approach to focal length coverage that reduces the need for multiple dedicated cameras.

Inventive Principle:
Principle #1Segmentation

2Measurement precision

If cooperative processing by multiple cameras is implemented, then image definition is improved, but the processing complexity increases

Engineering Contradiction:
Improveimage definitionVSAvoidprocessing complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent applies local quality by using different processing strategies for different image regions and camera contributions. The fusion algorithm selectively combines image data from the main camera and auxiliary camera based on the focal length range and quality metrics, rather than uniformly processing all images from all cameras. This localized approach improves definition where needed while reducing unnecessary processing complexity.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent changes processing parameters dynamically based on the shooting mode and focal length range. Different fusion weights, alignment parameters, and quality thresholds are applied depending on whether the system is in wide-angle, normal, or telephoto mode. This parameter adaptation optimizes image definition for each scenario while avoiding the complexity of a single overly-complex processing pipeline.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If full focal length coverage is achieved through multiple cameras, then shooting versatility is improved, but the coordination between cameras becomes more complex

Engineering Contradiction:
Improvefocal length coverageVSAvoidcamera coordination
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements preliminary action by pre-configuring the auxiliary camera parameters and fusion algorithms for different focal length ranges before actual shooting. The system pre-establishes the coordination rules between main and auxiliary cameras for wide-angle, normal, and telephoto modes, so that during shooting, the coordination follows predetermined patterns rather than requiring real-time complex decision-making.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces an intermediary processing layer that manages the coordination between the main camera and auxiliary camera. This intermediary system handles the complexity of camera selection, parameter matching, and fusion coordination, shielding the user from the underlying complexity while achieving full focal length coverage through seamless camera switching and combination.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

This application relates to the image processing field, and provides a method for image or video shooting and a related device. The method for image or video shooting includes: capturing images by using a first camera and a second camera based on the first zoom ratio and first lightness; processing the images captured, to obtain a shot image; and saving the shot image. In a photo mode in this application, by using a zoom ratio and lightness selected by a user, it is possible to determine to use the first camera and the second camera to capture images and perform processing. Therefore, different cameras can be used based on different lightness and zoom ratios to obtain images with different fields of view and different definition, and cooperative processing can be performed by using a plurality of cameras, to improve quality of a shot image obtained after the processing.
