Multi-Camera Control Allocation for Foreground and Background Apps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional multi-camera devices often grant control of all cameras to a single foreground application, preventing background applications from accessing or controlling cameras, even if they are unused, leading to interruptions and inconsistent image transitions.
Innovation Solution
Implementing systems and techniques that arbitrate camera control by granting unused cameras to background applications, allowing smooth transitions and consistent image data through settings determination based on data from multiple cameras.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If all cameras are granted to a single foreground application, then control simplicity is improved, but camera utilization efficiency deteriorates
Solution Approach 1:
The system segments camera resources by granting control of specific cameras to different applications based on their needs. The foreground application receives control of required cameras, while unused cameras are granted to background applications, enabling simultaneous multi-application camera access without conflict.
2Reliability
If background applications are prevented from accessing cameras, then foreground application performance is improved, but application versatility deteriorates
Solution Approach 1:
The system applies local quality by granting camera control rights selectively to different applications based on their specific needs and background/foreground status. Background applications can access and control cameras locally without interfering with foreground application operations, enabling diverse application scenarios to coexist.
3Stability of the object's composition
If camera control is monopolized by one application, then control consistency is improved, but system resource utilization deteriorates
Solution Approach 1:
The system transitions from a single-dimension control model (one application controls all cameras) to a multi-dimensional model where multiple applications can simultaneously control different cameras. This dimensional expansion allows background applications to access unused cameras while foreground applications maintain control of their designated cameras, achieving both consistency and resource utilization.

AI summary
Systems and techniques are described herein for managing control of cameras. For instance, a method for managing control of cameras is provided. The method may include receiving data output by two or more cameras of a plurality of cameras of a device; determining one or more settings for operation of the plurality of cameras based on the data; granting a first application running on the device control of a first camera of the plurality of cameras; receiving a request from a second application running on the device to control one or more cameras of the plurality of cameras; and granting the second application control of one or more unused cameras of the plurality of cameras.
