　　in Australia, Europe and the United States.

　　A market research shows that there has been a sharp rise in worldwide sales from 80 million mobile camera phones in 2003 to 1.14 billion by 2017.

　　Camera phones have not only been used for entertainment. In Sweden, a grocer snapped a shot of a robber and downloaded the photograph to his computer, which allowed the police to catch the suspect. In Italy, the same thing was done when a shop owner snapped pictures of two robbers. In Wales, doctors send photos of X­rays to consult a more experienced specialist about medical treatment for their patients. In Japan, the police have set up a website for citizens to send pictures of suspicious activities.

　　Now, newspaper reporters can use camera phones to take pictures of important events.

　　They can then send the pictures to their newspaper office. As the quality of camera phone pictures increases, we can expect to see camera phones used more and normal cameras used less.

　　More people are using their camera phones to take pictures of their trips, or just small unexpected things that happen in their daily lives. They can then send these pictures to friends anywhere.

　　However, camera phones have also been used to commit crimes. To prevent spying, these phones are not allowed in government buildings in the United Kingdom. Some car companies don't allow their employees to use their phones because they want to prevent some employees watching new car models and sensitive information secretly.
