CCD vs. CMOS Image Sensors in Machine Vision Update
In February 2011, we provided an analysis on the use of CCD versus CMOS image sensors in machine vision.

In August, we started a list of blogs that are a helpful resource on machine vision and industrial camera topics. We received some tips from our readers on additional great blogs.
The important starting point for machine vision applications is the details in the image. A higher quality starting image requires less software workarounds, which enables you to focus on your core technology. The question is then, are you getting the details you need from your image? Would a better image be beneficial?
Choosing the correct industrial camera for your machine vision system from the beginning can eliminate costly redesigns or upgrades in the future. The question is, how do you determine the best camera? Best is always subject to your needs. For Step 1, click here.

For intelligent traffic systems, VGA resolution CCD-based cameras have traditionally been the accepted technology, but with the quality of CMOS image sensors continuously improving, CMOS-based cameras are now a viable option for demanding license plate recognition applications. The latest system requirements are for higher resolution (HDTV) and frame rates of 30 to 60 frames per…
Intelligent Transportation Systems (ITS) are constantly becoming more sophisticated and one recent trend is the increased use of machine vision cameras. We at Adimec have several new customers and many more inquiries to use our cameras in intelligent traffic systems, primarily high speed license plate recognition applications for now. Some other traffic applications for our…
The latest machine vision camera technology can allow for improvements in intelligent traffic system (ITS) performance to minimize detection time in case of accidents, increase the detection rates in cases of violations, and minimize overall costs from police time and traffic jams. With decreasing budgets, these systems also need to maintain reasonable costs and prove…
Video camera-based intelligent transportation systems (ITS) are a broad category from automobile sensing systems, traffic management systems, toll collection systems, and more. ITS can be further broken down into those using automatic license plate recognition (ALPR) or automatic number plated recognition (ANPR).
Unlike what is shown on TV, you cannot zoom into a blurry image and expect to get more details. An image with acceptable sharpness and contrast must be acquired with the appropriate system from the start. This means the right image sensor, camera, optics, and lighting all combined in a reliable way.
