Embedded vision systems are everywhere: robots, drones, medical endoscopes, smart cameras. The interface that carries data from the sensor camera module to the processor is just as

A Low‑distortion lens is designed to keep straight lines straight, giving accurate geometry across the whole image.

Have you ever plugged a USB webcam into your computer and it just worked – no driver installation, no reboot? That convenience comes from a standard called UVC (USB Video Class). A

The lens is often the most overlooked part of a camera module. People focus on megapixels and sensor sensitivity, but a great sensor with a poor lens will still produce bad images.

Have you noticed that some security cameras show color during the day but switch to black‑and‑white at night? That’s thanks to an IR‑cut filter. This small optical component blocks

A VCM autofocus camera module uses electromagnetic force to move the lens precisely, achieving fast and quiet focusing.

In simple terms, focal length decides how “zoomed in” or “zoomed out” your camera’s view is. It affects how much of a scene you see and how big objects appear.

That’s lens distortion. In camera modules, distortion is when straight lines in the real world appear bent in the image.

Focal length is the distance from the lens to the sensor. Short focal lengths (2.5–4mm) give wide views, ideal for endoscopes and security. Long focal lengths (6–12mm) narrow the v

When choosing a camera module—for a medical endoscope, automotive safety system, or consumer webcam—lens material is a key decision. Glass and plastic are the two main options, eac

A fixed focus camera module has a permanently set lens. It relies on depth of field to keep objects sharp over a wide range. Advantages: simplicity, reliability, small size, low co

Autofocus automatically adjusts the lens position to keep the subject sharp. It uses contrast detection, phase detection, or laser ranging. Mechanisms include VCM, stepper motors,
