Camera Phone Review Introduction to Digital Pictures
When you take a photograph with any digital camera it converts the pictures and stores it as little dots of colour, each one known as a pixel. Pixels are important because they determine how good your photograph will look. The resolution and number of pixels in each picture will effect the overall quality.
In a mobile camera phone, a typical resolution may be quoted as 640 x 480 pixels, or 307,200 pixels in the overall picture. For newer camera phones the quality is improving with resolutions of 1.3 Mega pixels and picture sizes of 1280 x 960 pixels (as an aside this gives only 1.23 million pixels, which is rounded up to 1.3 by the manufacturers)
The more pixels in an image, the more memory each picture takes up. Your camera phone should have software that will compress the picture when it is stored, but this is likely to mean a loss in quality. For best results you will need to use the highest resolution and the highest quality storage format, but this means fewer photographs can be stored.
A picture taken at 1280 x 960 pixel resolution should print out reasonably well at a size of 6 inches by 4 inches (a standard photo size). If you try to enlarge it beyond this size however, it will look very grainy).
Getting your photographs out of your camera phone depends on what other technology you have, but include sending them direct to a printer (or to your computer) by bluetooth, infrared or USB, or sending them to another compatible camera phone.
