Cameraphone sales are expected to go as high as 295.5 million worldwide in 2005, that is 38 percent of all mobile phones introduced during the year, according to the market researcher Gartner. The growth is 24 percent in comparison with the shipments last year. The sales of mobile handsets with built-in camera in North America are expected to reach 70 million or 47 percent of total phone sales, in 2005. The increase of the sales comes as a result of the declining cost of embedding cameras into mobile phones. According to Gartner the cost of integrating a 1-megapixel camera into a phone may be halved over the next four years. He also expects that in advanced markets such as Japan and South Korea phones with cameras of higher-megapixel resolution will be preferred.
