What is a camera module?

A camera module is a compact electronic device that integrates various components required for capturing and processing images and videos. Commonly used in devices like smartphones, tablets, computers, security systems, and DIY projects such as those involving Arduino, it handles essential imaging functions. Typically, a camera module includes an image sensor, lens, interface circuitry, control circuitry, power management, and a protective mechanical housing for structural support.

What are the different camera modules

Camera modules are available in numerous types, each tailored to specific applications. Smartphone camera modules are equipped with high-resolution sensors, advanced autofocus, optical zoom, and image stabilization, designed to deliver top-notch photo and video quality.

In industrial applications, machine vision camera modules are built with high-speed sensors, rugged designs, and compatibility with industrial protocols, making them suitable for tasks such as quality control, inspection, and object recognition.

Surveillance camera modules focus on security, featuring remote monitoring capabilities and night vision. Raspberry Pi camera modules are favored by DIY enthusiasts for projects that involve photography, video recording, or computer vision applications.

What is the function of camera module

The primary function of a camera module is to capture images or videos. The image sensor, typically a CMOS or CCD sensor, plays a key role in converting light into electrical signals.

The lens focuses incoming light onto the sensor, determining the field of view and other optical characteristics. Interface circuitry allows the transfer of image or video data between the camera module and the host device.

Control circuitry manages various camera functions such as exposure control, white balance, focusing, and image processing. Power management regulates the necessary power supply for smooth operation. The mechanical housing provides structural support and physical protection for the camera module's components.
