Counterpoint Research publishes its estimation on automotive image sensor market shares: "The automotive camera sensor market is consolidated with ON Semiconductors accounting for around 50% of market share, followed by Omnivision, Sony and Toshiba, each accounting for 12-18% of market share. Other important players in the market includes Gentex and Melexis. The competition in the market is increasing with players introducing technologically advanced sensors."
IE 2008 publishes a paper " LED flicker: Root cause, impact and measurement for automotive imaging applications " by Brian Deegan, Valeo Vision Systems. " In recent years, the use of LED lighting has become widespread in the automotive environment, largely because of their high energy efficiency, reliability, and low maintenance costs. There has also been a concurrent increase in the use and complexity of automotive camera systems. To a large extent, LED lighting and automotive camera technology evolved separately and independently. As the use of both technologies has increased, it has become clear that LED lighting poses significant challenges for automotive imaging i.e. so-called "LED flicker". LED flicker is an artifact observed in digital imaging where an imaged light source appears to flicker, even though the light source appears constant to a human observer. This paper defines the root cause and manifestations of LED flicker. It defines the use cases wher...
