Superior CMOS Sensors

Last year the world‘s largest producer of CCD sensors, Sony, announced its plan to stop production of CCD technology and concentrate of the emerging CMOS sensor technology. Since then, many users have made the switch and started to benefit from the high speeds, lower price, reduced image noise and no blooming or smear. Take a read of some excellent examples where industrial cameras with CMOS sensors are coming out on top.


CMOS for Manufacturing

Industrial image processing has long been used for surface inspection of continuous materials such as glass and steel. Here, cameras are used to detect flaws.

A recent Steel manufacturing application used multiple 5 MP cameras with rolling shutter sensors from Aptina. The application runs at a relatively slow speed, allowing for 100% inspection. The cameras not along deliver high resolution and good image quality, but also come at a highly attractive price— the ideal combination for this kind of application.

CMOS in Sports Analysis

CMOS sensors can be a major aid outside the field of classic factory automation as well: one good example comes from the world of sports. High speeds are needed to record and replay rapid movements (such as through slow-motion), an essential part of the detailed analysis used in golf and tennis training. Speedy CMOS sensors from CMOSIS are perfect for sports applications. They are available in Basler ace cameras built around three different interface types (USB 3.0, GigE and CameraLink).

For the fastest variant (Camera Link), these sensors can handle up to 340 frames per second at 2 MP of resolution. An excellent fit for modern training methods, TV broadcasts and offer photographic support for judges and referees.


CMOS in Traffic

The market for Intelligent Traffic Systems (ITS) in particular demands a balance of image quality, speed and economy. Systems used for Automatic Number Plate Recognition (ANPR) and related applications must be able to handle a broad range of lighting conditions and vehicle speeds. High sensitivity Global Shutter sensors are particularly good at delivering crisp images of moving objects. The IMX 249 sensor from Sony is well suited here, given its broad dynamic range and high-speed compatibility.

Sensors from ON Semiconductor‘s PYTHON series are a strong choice when higher resolutions are needed, or when a project is particularly price sensitive.

In this picture taken by a CCD camera, only the light area of the license plate is visible. No interior image is captured.

This CMOS camera captures the light area around the license plate and the dark interior of the vehicle, including its driver.

CMOS in Microscopy

Medical applications place the most extreme demands on cameras. Conventional light microscopy for example – the images are used for observation, analysis and documentation, meaning that they must display rock-solid reliable, high resolution, sharp images with unwavering colour fidelity. These strict requirements in terms of image quality and speed are handled flawlessly by Sony‘s new generation of CMOS sensors.

The Pregius series offers impressive performance in a variety of areas, including the strong dynamic performance, high speeds and good colour fidelity needed for even the most difficult applications. Colour fidelity is enhanced perfectly in the Basler ace series, including the recently-introduced PGI feature set, which has further improved colour images captured by CMOS sensors. Integrated within the pylon Camera Software Suite, it offers users various options for adjusting colour characteristic further.
