Barcelona , Spain ( CNN ) -- Mobile phone giant Nokia on Monday unveiled a phone with a powerful 41 Megapixel camera as it attempts to reposition itself back at the forefront of the mobile market . The phone is among a dazzling array of new gadgets unveiled so far at the Mobile World Congress in Barcelona , an annual event that showcases the industry 's latest innovations .

The unrivaled camera capabilities of Nokia 's 808 PureView , which runs the company 's Symbian operating system , caused ripples of surprise among Congress delegates who predicted few surprises thanks to pre-event leaks and rumors . The 41 Megapixels put the phone in the same league -- in terms of photo resolution -- as professional cameras costing thousands of dollars . Reportedly priced at â‚¬450 ( $ 600 ) , the device is due to be released in May , with the camera technology likely to be carried over to other Nokia phones . Nokia , which in recent years has seen its dominance of the global mobile market eroded by manufacturers such as Apple and BlackBerry , also launched a lower-cost version of its flagship Lumia phone range . The Nokia 610 , priced at â‚¬189 , runs on the mobile version of Microsoft 's Windows 7 operating system . On Sunday , Chinese mobile maker Huawei made headlines with what it claims is the world 's fastest smartphone . The Ascend D quad features much-vaunted quad core technology -- twice the processing power of most new devices -- and runs Ice Cream Sandwich , the latest version of the Google-linked Android operating system .

Other hot gadget announcements include phones by Taiwanese manufacturer HTC . Its One X , One S and One V devices feature 4.3 inch screens made of toughened Gorilla glass and eight Megapixel cameras . Another surprise -- chiefly because the technology has proved unpopular in the past -- came in the shape of the Samsung Galaxy Beam , a phone featuring a built-in projector . The Android-powered device allows users to beam 50-inch wide video and photo images onto walls . Industry reviewers said the gadget appeared to work well during demonstrations in a darkened room . The as yet unpriced Galaxy Beam is expected to be in shops in the next few months . Barry Neild contributed to this story from London .
