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.

Here are a few sections directly from the report with the data, presented here with the permission of the AIA:

5.4 Sales by Sensor Type

We next examine sales by sensor type, which are summarized in Exhibit 5.5. As this exhibit shows, CCD sensors continue to be used in most cameras. In fact, CCD has managed to gain slightly over CMOS sensors, with CCD comprising nearly three‐fourths (74.7 percent) compared to CMOS at 19.4 percent as of 2011.

6.6 Sensor–related Trends

CMOS (complementary metal oxide semiconductor) sensors have made great inroads in the consumer market. Is this also the case in the machine vision market, with CMOS growing at the expense of CCD (charged‐coupled device) sensors? As we found in Chapter 5, the opposite is actually the case. In 2005, cameras with CCD sensors comprised 65.7 percent of units sold, while CMOS cameras accounted for 25.8 percent. As of 2011, the share claimed by CCD rose to 79.2 percent, while CMOS cameras declined to 19.5 percent.
