Rear Camera

Features of a Mobile Rear Camera

1. High Megapixel Count – Ranges from 12MP to 200MP+ in flagship models, allowing high-resolution photos.
2. Multi-Camera Setup:
   • Primary Camera – Captures standard photos with high detail.
   • Ultra-Wide Camera – Provides a wider field of view for landscapes and group shots.
   • Telephoto Camera – Enables optical zoom (2x, 5x, or even 10x) for distant subjects.
   • Macro Camera – Used for close-up shots with fine details.
   • Depth Sensor – Helps with portrait mode by creating a natural background blur (bokeh effect).
   • Periscope Lens – Found in premium phones, offering super zoom capabilities (up to 100x digital zoom).
3. Aperture Size (f/1.5 – f/2.8) – Determines light intake; wider apertures (lower f-number) improve low-light performance.
4. Optical Image Stabilization (OIS) & Electronic Image Stabilization (EIS):
   • OIS – Reduces blurriness in photos and videos by stabilizing the lens.
   • EIS – Uses software to enhance video stability.
5. Advanced Autofocus Technologies:
   • PDAF (Phase Detection Autofocus) – Quick and precise focus adjustments.
   • Laser Autofocus – Improves focus in low-light conditions.
   • Dual-Pixel Autofocus – Used in flagship models for ultra-fast focusing.
6. Night Mode & Low-Light Performance:
   • Uses AI processing and larger sensors to enhance details in dark environments.
7. HDR & AI Enhancements:
   • HDR (High Dynamic Range) balances shadows and highlights for more realistic images.
   • AI Scene Detection adjusts colors and settings based on the subject (e.g., food, landscape, portrait).
8. Zoom Capabilities:
   • Optical Zoom – True zoom without quality loss (2x, 3x, 5x, 10x).
   • Hybrid Zoom – Combines optical and digital zoom for better quality (e.g., 30x zoom).
   • Digital Zoom – Crops the image digitally but may reduce quality (e.g., 100x zoom).
9. Video Recording Capabilities:
   • Supports 4K, 8K, and slow-motion video recording.
   • High-end models feature cinematic video, Pro mode, and HDR10+ recording.
10. AI & Computational Photography:

• AI-powered portrait mode, night mode, and beauty filters improve photos automatically.
• RAW format support for professional editing and higher dynamic range.

11. Common Issues:

• Blurry or No Focus – May be caused by dirt, lens damage, or software issues.
• Camera App Not Opening or Crashing – Could be due to firmware bugs or hardware failure.
• Overexposed or Dark Photos – Results from incorrect settings or lighting conditions.
