Multi-Focus Image Acquisition for Mobile Cameras
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile phone cameras can only determine a single focus position, either close or distant, and cannot simultaneously capture clear images of both, limiting their image processing capabilities and user experience.
Innovation Solution
A method and device that allow users to select multiple focus positions using a multi-focus shooting mode, enabling the acquisition and processing of images from different planes, which are then combined to produce a single clear image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If single focus determination is used, then the image acquisition process is simple, but multiple focuses in different planes cannot be determined simultaneously
Solution Approach 1:
The patent divides the image acquisition process into multiple independent focus determination steps. Each focus position (first focus, second focus, etc.) is determined separately through independent image acquisition operations, allowing multiple focuses in different planes to be captured simultaneously while maintaining operational simplicity through structured processing
2Adaptability or versatility
If multiple focuses in different planes are determined, then the image processing capability is improved, but the device complexity increases
Solution Approach 1:
The patent combines multiple focus-determined images through a merging process that integrates first image information, second image information, and third image information into a unified result. This merging mechanism consolidates the complexity of multi-focus processing into a single integrated output, improving versatility while managing system complexity through coherent data fusion
3Device complexity
If single-focus shooting mode is used, then the device structure remains simple, but the processing capability is not effectively improved
Solution Approach 1:
The patent introduces dynamic processing modes that can operate in different states: single-focus mode for simple scenarios and multi-focus mode for complex scenarios. The system dynamically switches between processing approaches based on the shooting requirements, maintaining structural simplicity while effectively improving processing capability when needed through conditional activation of advanced processing functions

AI summary
The present application provides a method and device for acquiring an image, the method including determining at least a first focus and a second focus in an image acquisition area; acquiring first image information in the image acquisition area corresponding to the first focus; acquiring second image information in the image acquisition area corresponding to the second focus; and processing the first image information and the second image information to obtain third image information, so as to solve the technical problem in the prior art when a photo is taken by means of determining a single focus or multiple focuses, focuses in different planes cannot be determined, such that a mobile phone can merely process images in a single way and fails to record images corresponding to multiple focuses simultaneously, resulting in the processing capability of an electronic apparatus not being effectively improved.
