Apple supplier Sony takes hit in December quarter on lower image sensor sales

"Demand for image sensors from certain customers has slowed since November due to a slowdown in the high-end smartphone market," said CFO Kenichiro Yoshida during a media briefing, according to Reuters. The quarter's device sales, including image sensors, fell 13 percent year-over-year, contributing to a loss of 11.7 billion yen ($96.62 million) in the segment versus last year's 53.8 billion yen ($444.3 million) profit.

The company's mobile division saw sales fall 15 percent. Although Sony's Xperia phones are generally well-reviewed, they haven't sold nearly as well as the iPhone or Samsung's Galaxy products.

Sony is believed to be the only image sensor supplier for the iPhone, meaning that any shift in iPhone production can have a significant impact on the company.

During a Tuesday results call, Apple CEO Tim Cook admitted that iPhone sales will probably see their first-ever decline in the March quarter. This would square up with claims that Apple was instituting a 30 percent production cut for the period. A number of other Apple suppliers have experienced setbacks as well, including Foxconn.
