Multi-Camera Image Capture System for Mobile Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices face challenges in capturing high-quality images due to size constraints on camera lenses, which limits their ability to optimize images under various conditions with a single method.
Innovation Solution
An image capturing system comprising six cameras with different lenses (wide angle, standard, and long focal length) and a processor that generates optimized images by combining and processing images from multiple cameras, including super-resolution, high dynamic range, parallax estimation, and zooming images, to enhance image quality and adapt to varying conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If a single camera with limited lens size is used in mobile devices, then the device size is kept small and light, but the image quality and optimization capability under various conditions deteriorates
Solution Approach 1:
The image capturing system is segmented into multiple independent camera modules, each with specialized lenses for different functions (wide angle, standard, telephoto). This allows each camera to be optimized for specific conditions while keeping individual lens sizes small, resolving the contradiction between device weight and image quality.
Solution Approach 2:
The multi-camera system provides universal image capture capability across various conditions (landscape, portrait, low-light, zoom) using different camera combinations. The system can switch between or combine cameras to handle diverse shooting scenarios, making the device adaptable to all conditions without requiring a single large heavy lens.
2Device complexity
If one single image optimization method is used, then the system complexity is reduced, but the ability to satisfy users under all kinds of situations deteriorates
Solution Approach 1:
The system dynamically selects and combines different cameras and optimization methods based on the shooting conditions. The processor automatically determines the optimal camera combination and processing algorithm for each situation, providing adaptability without requiring user intervention or overly complex manual configuration.
Solution Approach 2:
The system changes processing parameters (such as which cameras to use, exposure settings, image combination algorithms) based on the shooting conditions. By dynamically adjusting these parameters, the system adapts to different situations while maintaining a unified control interface, balancing versatility with manageable complexity.

AI summary
An image capturing system includes a first camera having a first lens, a second camera having a second lens, a third camera having a third lens, a fourth camera having a fourth lens, a fifth camera having a fifth lens, a sixth camera having a sixth lens, and a processor coupled to the six cameras. The processor generates an optimized image according to images captured by at least two of the six cameras. The first lens, the second lens, the third lens and the fourth lens are disposed adjacently. The first lens, the third lens, the fifth lens, and the sixth lens are disposed along a straight line. Fields of view of the first lens, the second lens, the third lens, and the fourth lens are the same.
