Considerations with ultra high resolution (12 MP+) machine vision cameras

Posted by Gretchen Alper on Fri, Nov 23, 2012

For many applications, machine vision cameras with increased resolution can offer advantages such as increased field of view or greater accuracy.  Now ultra high-resolution cameras (greater than 12 Megapixels) are available with acceptable frame rates such as 12 Megapixels at 66 fps.  With this change, there are some considerations…

CCD vs CMOS Entering the Slope of Enlightenment

Posted by Gretchen Alper on Tue, Jun 12, 2012

The trend in 2011 towards increased CCD image sensor use over CMOS, was contrary to what was expected.  We believe this is just a slow adoption of new technology and not an indication of any long-term trends.  Regardless of the differing available data we still believe that CMOS image sensors will be used significantly more in machine vision.  CMOS image sensors are just coming out the other side of the Hype Cycle as defined by Gartner Inc

CCD vs. CMOS: Increased CCD use in Machine Vision?

Posted by Gretchen Alper on Fri, Jun 8, 2012

There has been a lot of talk (us included) about the use of CMOS image sensors taking over CCD image sensors in machine vision.  Recent data reported in the 2012 AIA Machine Vision Camera Study, shows that the opposite was true in 2011.  We at Adimec still believe CMOS image sensors will gain significant adoption in machine vision in the coming years, which we will explain further in another blog.

CCD versus CMOS in Traffic Applications

Posted by Gretchen Alper on Mon, Jan 30, 2012

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 second as well as all of the following: color, NIR sensitivity, high dynamic range, and low noise at high gain.  Imaging systems for traffic are exposed to extreme lighting and temperature conditions which affect the image quality.  So what are the advantages and disadvantages of choosing a camera based on a CMOS image sensor versus a CCD image sensor?
