A powerful, high-performance React Native Camera library, VisionCamera addresses the need for advanced camera functionalities within mobile applications. It targets React Native developers seeking to integrate sophisticated features like real-time AI processing, high-resolution capture, and custom camera controls, thereby enabling richer user experiences.

How It Works

VisionCamera employs a high-performance architecture, utilizing custom C++/GPU accelerated resizing with Metal/Vulkan for optimal performance. A key feature is its real-time Frame Processors, which allow JavaScript worklets to execute directly on camera frames. This enables low-latency processing for tasks such as AI object detection, facial recognition, and applying real-time filters or shaders.

Quick Start & Requirements

• Installation: npm i react-native-vision-camera followed by cd ios && pod install.
• Prerequisites: A standard React Native development environment. Camera permissions must be configured within the application.
• Documentation: Official documentation is available via a Documentation Website. An Example App and a Community Discord are also provided.
• Demo: The ShadowLens example showcases the library's capabilities.

Highlighted Details

• Supports high resolutions (up to 4k/8k) and high frame rates (30-240 FPS).
• Features real-time Frame Processors for advanced JS worklet-based image analysis and manipulation.
• Includes custom C++/GPU accelerated resizing (Metal/Vulkan) for enhanced performance.
• Offers advanced camera controls such as smooth zooming, HDR, and Night modes.

Maintenance & Community

Developed by Margelo, the project maintains an active community on Discord. Developers can follow updates via Twitter and find additional examples on the developer's blog.

Licensing & Compatibility
