CameraApp - Professional Android Camera & AR Application

CameraApp is a high-performance Android camera application designed to demonstrate advanced image processing, manual hardware control, and machine learning integration. Built with modern Android architecture, it leverages the power of GPU for real-time effects and ML Kit for intelligent face tracking.

🚀 Key Features

1. Full Manual Control (Pro Mode)

• ISO: Manual sensitivity control ranging from 100 to 6400.
• Shutter Speed: Precision control from 1/10s to 1/1000s to capture motion or low-light scenes.
• White Balance: Kelvin-based manual adjustment (2000K - 10000K) using custom RGB gains.
• Manual Focus: Tap-to-focus functionality with a visual focus ring feedback.

2. Custom OpenGL ES Image Processing Pipeline

• Real-time Filters: All image processing is offloaded to the GPU using OpenGL ES 2.0 for lag-free performance.
• Advanced Shaders:
  • Convolution Matrices: High-pass filter for the "Sharpen" effect.
  • Color Transformation Matrices: Used for Vivid, Sepia, and B&W filters.
  • HDR Simulation: Implements the ACES Filmic Tone Mapping algorithm to digitally enhance dynamic range.

3. ML Kit Face Detection & AR

• Intelligent Tracking: Uses Google ML Kit to detect faces in the camera stream asychronously.
• Dynamic AR Filter: A "Sunglasses" filter that automatically scales, positions, and rotates based on the user's eye coordinates and head tilt.
• Mirror Effect Correction: Corrects mirroring and rotation logic for seamless AR experiences on both front and back cameras.

4. Professional Capture & Storage

• RAW (DNG) Support: Ability to capture uncompressed 10/12-bit digital negatives for professional post-processing.
• Filtered JPEG: Captures the exact frame processed by the OpenGL pipeline, burning the selected filters and AR elements directly into the image.
• Hardware Discovery: Automatically detects and handles multiple lenses, including Wide Angle support if available on the device.

5. Advanced Gallery

• Fullscreen Viewer: Browse photos with a high-performance ViewPager2 implementation.
• Metadata Viewer: View technical details such as file path, size, type, and capture date.
• Safe Deletion: Permanent file deletion with user confirmation.

🛠 Technical Stack

• Kotlin: Primary development language.
• CameraX & Camera2 Interop: Low-level hardware control through a modern API.
• OpenGL ES 2.0 & GLSL: Shader programming for GPU-based effects.
• Google ML Kit: On-device machine learning for face detection.
• View Binding: Type-safe UI component access.
• Material Design 3: Modern and intuitive user interface.

📥 Installation & Setup

Follow these steps to run the project locally:

1. Clone the Repository:

   git clone https://github.com/cemgolo/CameraApp.git

2. Open in Android Studio:

   • Launch Android Studio.
   • Select File -> Open and choose the cloned KameraDeneme2 folder.

3. Sync Gradle:

   • Wait for the IDE to download dependencies and sync the project.
   • If prompted, click Sync Project with Gradle Files.

4. Device Requirements:

   • Real Device Recommended: Due to OpenGL and Camera2 hardware requirements, a physical Android device (API 24+) is strongly recommended over an emulator.
   • Ensure the device supports the Camera2 API.

5. Run the App:

   • Connect your device via USB or WiFi.
   • Click the Run (Green play) button in Android Studio.

📸 Usage

• Switching Modes: Use the bottom selector to toggle between Photo and Wide-angle modes.
• Applying Filters: Tap the star icon in the top bar to reveal the filter strip.
• Manual Settings: Tap the gear icon to open sliders for ISO, Shutter Speed, and White Balance.
• Focusing: Simply tap anywhere on the camera preview to lock focus on that specific point.
