In February 2011, we provided an analysis on the use of CCD versus CMOS image sensors in machine vision.
The Vision Trade Fair 2011 held in Stuttgart November 8th to 10th was the most successful to date, with 323 exhibitors breaking the 300 mark for the first time as well as setting a new visitor record of 6,752 highly qualified visitors. This is great news about the growth of the machine vision market!

OEM system developers typically consider industrial video cameras that contain a particular image sensor, and then base their final decision on baseline needs such as camera outline and unit price. While the image sensor selection is important, the fact that several cameras use the same image sensor does not mean the cameras from different vendors will produce the same image, or even meet the requirements of specific vision applications. But what parameters are determined by the camera and how can you determine the right fit for your system?
Why is it that cameras for consumer electronic products, e.g. smart phones have more than 5 megapixel tiny cameras that cost next to nothing, are not used for machine vision?
CMOS sensor based defense cameras are gaining ground, but for long-term, reliable, high image quality applications, CCDs will continue to be the preferred option for a while.
On February 8th, we discussed the CCD vs. CMOS sensors in machine vision cameras. We discussed that CMOS image sensors have shown significant improvements in quality and are quickly approaching that of CCD sensors, especially when sophisticated camera technology is used to optimize image uniformity. Our conclusion was that more and more, CMOS-sensor based cameras are a good option for many machine vision applications now and this trend will continue.
