Camera modules are one of the most important parts of modern smartphones. They are responsible for capturing photos, recording videos, scanning QR codes, and even supporting facial recognition features.
Without a working camera module, a phone cannot take clear pictures or videos.
What Is a Camera Module?
A camera module is the complete camera unit inside a smartphone. It combines several components to capture images.
A typical camera module includes:
- Camera sensor
- Lens
- Autofocus system
- Flash connection
- Flexible cable connector
- Protective housing
These parts work together to convert light into digital images.
Main Types of Camera Modules

Also called the selfie camera.

Modern phones now use high-megapixel front cameras for clearer selfies and social media content.
