Sony saw higher sales and profits in the quarter from April to June this year, although it saw disappointing results in some key product categories.

The company said Thursday that sales rose 13 per cent against the same period last year to ¥2.0 trillion (£7.76 billion), and net income more than doubled to ¥66.5 billion. Some of the gains during the quarter came thanks to the strength of the Japanese yen, which makes Sony's products more competitive overseas.

Its core electronics sector reported a an 11.6 percent jump in sales on the back of demand for digital still cameras, flat-panel televisions and digital video cameras. Operating income jumped 77.3 percent mainly because of higher profits from Cybershot cameras, Handycam video cameras and semiconductor chips. The Bravia LCD (liquid crystal display) TV business saw losses widen in the quarter.

Electronics sales were ¥1.4 trillion, accounting for about two-thirds of sales during the period, and the unit contributed ¥84.1 billion to Sony's overall operating profit of 99.3 billion.

In the game sector losses increased on the back of poor sales of the PlayStation 3 console. Sony sold 710,000 of the consoles during the quarter while software sales hit 4.7 million units. PlayStation 2 sales rose slightly to 2.7 million units and PlayStation Portable sales increased by 730,000 units to 2.1 million units. Overall game unit sales rose 60.5 percent but losses were ¥29.2 billion.

Sony kept its current year financial forecast unchanged at sales of ¥8.78 trillion and net income of ¥320 billion.
