Nikkei publishes article on Sony image sensor business saying:"Sony will cut costs, raise production yields for new offerings and increase sales of image sensors used in automobiles. The moves aim to shield the semiconductor business from highly volatile smartphone demand.
Sony holds the leading global market share of nearly 50% in value terms for image sensors, Techno Systems Research says. But competition from No. 2 Samsung Electronics and others is growing."
TSR appears to be quite optimistic in its estimation of Sony share. Other analysts give Sony "only" 35-40% of the market.
