With the advent of computing power and higher resolution CMOS sensor, imaging camera for mobile phone application has become very common in consumer portable product such as mobile phone, tablet or even wearable devices and head mount devices . Higher resolution image sensor, on the other hand, will suffer chromatic aberration (CA) where the colour channel appears shifted. Better lens design with more lens elements may be required. However, this will add more cost and manufacturing challenges. Many studies and methods have been proposed for CA correction through post image processing and those methods required calibration or post image process before correction factor can be applied. In this paper, we propose a new algorithm that will pre-defined the CA correction factor through lens design simulation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
