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,

When you look at camera module specs, you’ll often see something like “f/1.8” or “f/2.0.” That’s the aperture. But what does it actually mean? In simple terms, aperture is the open

Ever tried to take a group photo and couldn’t fit everyone in the frame? Or used a security camera that only captured a narrow slice of a parking lot? That’s field of view (FOV) at

The lens is equally critical—it determines what the camera sees, how sharp the image is, and how well it performs in different conditions.

Both have their place. A 2MP cmos module camera excels in low light, high speed, and cost-sensitive applications. An 8MP module delivers the detail for high-end automotive, wide-ar

Ever tried to take a photo in dim lighting and ended up with a dark, grainy image? That’s a sensitivity problem. In camera modules, sensitivity determines how well the camera perfo

Machine vision is what lets industrial equipment “see.” It’s used for quality control, robotic guidance, barcode reading, and countless automation tasks.
