The owner of the Dixons and Currys brands in the UK will purchase a 75 per cent share for a total of 266 million euros (£184 million).
FotoVista owns Pixmania, a leading European online retailer of digital photographic and consumer electronic products. The e-tailer is the market leader for online consumer electronics in France, Italy, Spain and Portugal. It has a presence in 25 European countries, including all those where DSG operates.
FotoVista also operates 250 stores in France and an online digital photo service. For the financial year to March 31, the company reported pre-tax profits of 7.6 million euros (£5.3 million).
DSG chief executive John Clare said: 'We will be supporting Pixmania's growth plans with our buying, supply chain, service and back office infrastructures to enable it to become a very much stronger pan-European business in a broader range of electricals and related products over the next few years. In most European countries, e-tailing is in its infancy with highly promising growth prospects.'
The acquisition is expected to take place before the end of June and is subject to approval by the EU Competition Authority.
Last week, DSG announced that its Dixons brand in the UK will move exclusively online, rebranding the existing 190 Dixons high street stores as Currys.digital.
