Sony has purchased Toshiba's image sensor business for 19 billion yen, or around $155 million, confirming rumors from October. It recently re-organized its sensor division into a wholly-owned subsidiary called the Sony Semiconductor Corporation. The move will bolster the new company and remove Toshiba as a primary competitor in the smartphone and camera image sensor business. Sony manufacturers such chips for its own smartphones along with models by the likes of Apple and Xiaomi. Its chips are also used in DSLRs made by Nikon and its own Alpha models.
