3. Feature of mobile phones cont.

There are a number of other features available on mobile phones. These include:

Radios

Many mobile phones can pick up any radio stations in your area so you can listen to your favourite radio channel

Cameras

Most mobile phones now contain a camera.

The quality of the camera is determined by its resolution. A typical mobile camera has a resolution of 2 - 5 Megapixels.

To give you an idea of the quality needed, a 3 Megapixel photo can be enlarged perfectly well up to A4 size.

The higher the Megapixels the more detailed the photograph becomes.

However the picture files also become larger.

The file size of each photo is important because

• The larger the photo, the longer it takes to send.
• The larger the photo the fewer you can store in the mobile's memory.

Some mobiles even have a small flash to allow photos to be taken in low light.
