Camera Samples
A collection of reference implementations and code samples for integrating Android camera hardware and software APIs. The project provides demonstrations for using both the Jetpack CameraX library and the low-level Camera2 API to implement photo and video capture features.
The repository includes specialized implementations for high-performance recording, such as high-frame-rate slow motion and high-dynamic-range video. It also features examples of machine learning vision, demonstrating how to analyze live camera frames for object detection and QR code scanning.
The project covers broad imaging capabilities, including still image acquisition, live viewfinder rendering, and video quality configuration. It further details the use of manufacturer-specific hardware extensions to apply effects like bokeh, night mode, and HDR.
The samples include utilities for coordinate mapping to render visual overlays and event monitoring to track recording states.

Star history
How this analysis was created: This summary and feature list were written by an AI model that read the project's README and public documentation pages. Each feature links to the documentation it came from; stars, license and language come straight from the GitHub API. The model does not read the source code, and the analysis is refreshed when the project is re-analysed. Learn more on our About page.
