Samsung Build Its Own Image Sensors To Challenge Sony.
Sony was the first to build a mobile camera with on-chip memory(Motion Eye camera). The camera was build on Xperia XZ Premium and XZs (later XZ1 too). That Samsung Semiconductors is looking to build own similar camera in November, will ready to use in the next-generation Galaxy S phone.
It uses a two layer chip to which a DRAM chip is bonded. Apparently this is to avoid infringing certain patents. The advantage of on-chip memory is the camera can store many frames with fast. It can shoot 1,000fps or so for slow-motion video.
