Tilting Dual Camera Assembly for Wide-Angle Synthesis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wide-angle cameras in mobile terminals suffer from increased picture distortions due to the fixed area of the camera light sensing chip, limiting their ability to capture large-scale photographs with good details.
Innovation Solution
A camera assembly comprising two non-wide-angle cameras positioned on a base that can be tilted, allowing their back surfaces to lean towards each other, expanding the photographing range and enabling the synthesis of multiple pictures into wide-angle images with improved detail and feature capture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If a wide-angle camera is used to capture large-scale photographs, then the photographing range is expanded, but picture distortions increase due to the fixed area of the camera light sensing chip
Solution Approach 1:
The patent divides the wide-angle photographing function into multiple non-wide-angle cameras arranged in an array. Each camera captures a portion of the scene with high quality, and the images are later synthesized to create a wide-angle view without the distortions inherent in single wide-angle lenses.
Solution Approach 2:
The patent arranges multiple cameras in a specific spatial configuration (array) rather than using a single camera. This spatial arrangement in multiple dimensions enables wide-area coverage while maintaining image quality by capturing light from different angles and positions simultaneously.
2Area of moving object
If multiple cameras are arranged to expand photographing range, then the photographing coverage increases, but the device complexity increases
Solution Approach 1:
The support bracket structure serves multiple functions: it holds multiple cameras, provides adjustable positioning mechanisms, enables angle adjustment, and facilitates synthesis control. This multi-functional design reduces the need for separate components for each function, thereby managing complexity while achieving wide coverage.
Solution Approach 2:
The patent incorporates adjustable mechanisms that allow the cameras to change their relative positions and angles dynamically. This enables the system to adapt to different photographing scenarios and optimize image quality and coverage based on specific requirements, rather than being fixed in a single configuration.
3Manufacturing precision
If non-wide-angle cameras are used instead of wide-angle cameras, then image quality with good details is maintained, but the photographing range is limited
Solution Approach 1:
The patent combines multiple non-wide-angle camera images through synthesis processing to create a composite wide-angle view. This merging of multiple high-quality images achieves both wide photographing range and good image details that would be difficult to obtain with a single wide-angle camera.
Solution Approach 2:
The system uses multiple copies of non-wide-angle cameras rather than a single wide-angle camera. Each camera creates a high-quality copy of a portion of the scene, and these copies are synthesized to form a complete wide-angle view with preserved details from each individual camera.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration allows two non-wide-angle cameras to take broader pictures with good details and features, eliminating the need for a dedicated wide-angle camera, while maintaining or improving image quality by adjusting the camera angles and using a control structure to rotate the cameras between parallel and tilted states.
Implementation Method 1

AI summary
A camera assembly includes a base (1), and two cameras (2A, 2B) located on the base (1). When the base makes the two cameras (2A, 2B) in a tilted state, an angle between a first plane (21) and a second plane (22) is greater than 0 degree and less than 180 degrees, and back surfaces of the two cameras (2A, 2B) are opposing each other. The first plane (21) is a plane perpendicular to an optical axis (A, B) direction of one of the two cameras (2A), and the second plane (22) is a plane perpendicular to an optical axis (A*, B*) direction of the other one of the two cameras (2B). The technical scheme can take a broader picture with comparatively good details and features.
