After two years of record profits, Sony is now facing headwinds in the games business, central to the company's recent revival.

The gaming business is expecting larger costs to develop a next-generation console that analysts say will come in 2020, as the five-year old PlayStation 4 nears the end of its life.

But bigger profits at the image sensor business, driven by demand for large-size image sensors and multiple-lens camera systems for smartphones, offset the weakness in the gaming business.

The semiconductor business, which includes image sensors, posted a profit of 49.5 billion yen, up from 29.1 billion yen a year earlier.

The gaming business posted a profit of 73.8 billion yen, down from 83.5 billion yen a year earlier.
