Camera Preview Control for Multi-Camera Depth-of-Field Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile phone cameras allow only single photographing mode selection, leading to poor image quality and inability to meet diverse user needs.
Innovation Solution
A photographing method and apparatus that enables users to select and control multiple cameras through a target control on the camera preview screen, allowing for different depth-of-field ranges and compositing images from these cameras to produce a target image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a select button is added to allow users to choose one camera, then users can select different cameras for photographing, but the operation becomes more complex and time-consuming
Solution Approach 1:
The camera selection interface is segmented into multiple camera icons displayed simultaneously on the preview screen, allowing users to directly tap the desired camera without navigating through additional menus or windows. This segmentation presents all camera options in a simplified, accessible manner.
Solution Approach 2:
Multiple camera icons are displayed in advance on the preview screen before the user makes a selection. This preliminary display of all available cameras eliminates the need for users to navigate through pop-up windows or additional menus, enabling direct selection and reducing operational steps.
2Ease of operation
If only one camera is selected for photographing, then the camera system is simpler to operate, but the image quality and depth-of-field control are limited
Solution Approach 1:
The system dynamically adjusts the depth-of-field by controlling multiple cameras with different focal lengths to photograph simultaneously. The processing unit dynamically composites these images based on real-time depth-of-field requirements, enabling flexible image quality optimization without complicating user operation.
Solution Approach 2:
The system uses composite imaging by combining photographs from multiple cameras with different focal lengths. The processing unit composites these multiple images to create a final image with optimized depth-of-field and quality, analogous to using composite materials to achieve superior properties.
3Manufacturing precision
If multiple cameras are used to photograph different depth-of-field ranges, then the image quality and depth-of-field control are improved, but the device complexity increases
Solution Approach 1:
Multiple cameras with different focal lengths are integrated into a single camera system that serves multiple functions: wide-angle photography, portrait photography with background blur, and macro photography. This multi-functional design enables diverse depth-of-field control without requiring separate devices.
Solution Approach 2:
The system merges multiple cameras with different focal lengths into a unified camera system. The processing unit combines the photographs from these cameras into a single composite image, effectively merging their capabilities to achieve superior depth-of-field control while maintaining a single integrated device.
4Adaptability or versatility
If a pop-up window is used for camera selection, then users can select different cameras, but the operation time and steps are increased
Solution Approach 1:
Multiple camera icons are displayed in advance on the main preview screen interface. Users can directly tap the desired camera icon without needing to open or navigate through a separate pop-up window, significantly reducing the time and steps required for camera switching.
Solution Approach 2:
Instead of hiding camera options in a pop-up window that requires opening and closing, the system inverts the approach by displaying all camera icons directly on the main preview screen. This reversal of the traditional interface design eliminates unnecessary navigation steps and accelerates camera switching.

AI summary
This application discloses a photographing method and apparatus, an electronic device, and a storage medium, and pertains to the field of imaging technologies. The method includes: receiving a first input from a user on a target control in a camera preview screen, where the target control includes a first region and the first region corresponds to N depth-of-field values; displaying M camera icons in a second region of the target control in response to the first input, where each camera icon corresponds to one depth-of-field range; and controlling M cameras to photograph images and outputting a target image, where the target image is obtained by compositing the images photographed by the M cameras.
