Evaluating Machine Vision Cameras versus Comparing Camera Specification Documents

Posted by Gretchen Alper on Wed, Jan 30, 2013

Many of our customers ask us how they should evaluate cameras in order to find the best solution for their application. There are several reasons why we feel the Photon Transfer Curve (PTC) is useful, especially if you are trying to get the most out of your imaging system such as when detecting small differences between images or using the pixel information as data for measurements. We have shared some detailed information on how to measure the Photon Transfer Curve for CCD or CMOS machine vision cameras because we feel it is an important part of camera evaluation and selection.

5 Steps to Prepare for a Machine Vision Camera Evaluation

Posted by Gretchen Alper on Wed, Jan 16, 2013

It is hard to do a good comparison of machine vision cameras based on the paper specifications.  For instance some give dynamic range while other provide sensitivity.  These two are related but not the same.  Even cameras using the same image sensor do not perform the same.  Seeing and testing the cameras for yourself is most likely required for the right decision.
