A compact image capturing system called TOMBO (thin observation module by bound optics) is developed with compound-eye imaging and post digital processing. To demonstrate effectiveness of the TOMBO architecture, several prototype systems have been constructed with a refractive microlens array and a CMOS (complementary metal oxide semiconductor) image sensor. As a new algorithm for image reconstruction, the pixel rearrange method has been developed. With several test targets, the characteristics of the prototype systems are evaluated.© (2001) COPYRIGHT SPIE--The International Society for Optical Engineering.
