Sony Corp. revealed that it plans to start selling smartphone camera modules soon, instead of just image sensors. The decision is believed to be aimed at signing up contracts with Apple Inc. and other leading smartphone manufacturers. Sony is the global leader in CMOS image sensors, with a market share of about 40% in the image sensors used in smartphones, including those manufactured by Apple and Samsung Electronics Co. Sony plans to boost its current manufacturing of camera modules to more than 10 million units, from the current approximately 1 million units, at its China factory within the next two to three years.
