According to a report by Reuters Japanese electronics manufacturer Sony has lifted its operating income estimate for the financial year ended March 31. Sony says it now expects an income of around Â¥285 billion ($2.6 billion), which is up from a 240 billion yen estimate in February.

The main reason for the adjustment of the estimate are lower amortization costs for Sony's financial services segment but the company also cites lower-than-anticipated costs for its image sensor business. The company doesn't provide any more detail than that, so we can only speculate what those anticipated costs were. 

Sony's semiconductor business has been a market leader for years with a dominating market share of around 40 percent. Sony sensors have been deployed in the cameras and smartphones of a large number of vendors. The company will report its full-year results on April 28.
