Framos 2014 survey on machine vision market paints an interesting picture. "The study is based on answers from 54 respondents based in 13 countries, 10 manufacturers and 44 users, with the main focus on German-speaking countries and Europe. Respondents were ranked in terms of relevance, based on the production or purchase volumes on which they were surveyed. 40% of the manufacturers produce up to 500 cameras a year, 20% over 10,000 cameras. Principal sales areas are North America and Asia. 80% of users purchase fewer than 100 cameras a year, only 5% require more than 1000 cameras. The main area of use is Europe, at 75%, due to the focus of this survey."
Here is the respondents view on CCD vs CMOS market evolution:
"In respect of sensor brands and their future use in imaging systems, camera manufacturers and users are agreed on their decline or rise. Sensors from Sony may have less usage in percentage, but continue to be the most trusted brand, with a predicted market share of 35% in 2016. In particular, considerable growth is expected for the brands Aptina and Truesense Imaging (both now under one roof, belonging to OnSemi), to a market share of 13% and 19% respectively."
