I'm getting a new phone and I want good camera quality.
Can somebody show me what a 1.3 megapixel picture looks like?
Answer
Cameras in phones tend to produce poor quality images, especially when compared to digital cameras with the same resolution. Generally speaking a 1.3 megapixel image would be good for emailing and posting online.
When viewed on a monitor, the image would be a nice size and show detail without much distortion. Printed images would be different.
Megapixels refers to the size of an image, not the quality. The approximate size of a 1.3MP image would be 1280X1024 (in pixels), which is what many people use as their monitor resolution these days. Printed, it would only produce a print of about 3X5 inches before the image would start to look bad. Basically, the viewable size would be the same as your monitor screen, but the printed size would be much smaller. The real indicator of quality is PPI (DPI) which is the number of printable pixels per inch in a given image. Some 1.3MP cameras can produce images with 200 PPI while others only have 72 PPI. This is where the difference in viewed and printed images comes from. The lower the PPI, the lower the quality of the image. Most 1.3MP camera phones I know of only produce 72 PPI images.
Bear in mind that camera phones don't have a flash or any modes for taking pictures. The sensor and mechanism tend to be a one size fits all proposition which means many pictures don't fair well, especially if they are moving or in low light.
This camera phone would be a good choice for saving images to share online, but not so good for printing for a photo album.

My 1.3 MegaPixel Camera....?
AladdinZan
I had a 5MP camera and it broke. It just stopped working for no reason.
So I started using a Photoclip 5 in 1 that I had years ago and shelved. It is fantastic. The photos are very very good quality and I am surprised - even when I am not using the full size pics.
How can this be so? Surely 5MP pics must be better, or is it the build quality of the camera?
Answer
Are you viewing these on your PC? If so than that would be the main reason. Resolutions beyond a MP or two generally only make a difference in print.
More than that though, and despite what the camera makers would have you believe, megapixels definitely aren't everything. The quality of the lens plays a big part as well. While it sounds a bit counterproductive for a camera maker to stick a sensor with higher resolution than the glass in front of it could resolve in the first place, this often the case. Detail destroying "noise" is another factor. Ironically as you increase the number of pixels, as a rule this also goes up. On many recent compact digitals it has gotten to the point where this noise is so severe that at best it completely cancels out any resolution benefit these cameras would otherwise have had!
