Samsung has released the first mobile phone with an eight-megapixel image sensor that can produce quality images on a par with most digital cameras. Called the Samsung i8510, the new model comes with a flash and can detect when people are smiling in the picture. This may be the first product to go on sale in Britain with an eight-megapixel camera, but other manufacturers such as Sony Ericsson are developing similar products for release. Previous camera phones have been criticized for its poor image quality. However, one expert said that the emergence of this Korean company’s new phone model could mean that the average consumer no longer need to buy a camera.
