my vga camera on sharp gx15 was very good in quality compared to my new ericsson Z550i 1.3 megapixel camera. the new phone's pictures look very dirty full of dots everywhere even on the highest best quality. Can anybody tell me why this is? And also if picture quality does not depend on megapixels then how does a person determine which camera will be better?
Answer
Megapixel count determines the size of the photo and assures more colors. Hopefully more colors will lead to more realistic photos.
But a camera is also very dependent on the lens to produce breat photos. In fact, the lens is the more important part of the camera. In your case, it may not matter much because camera phones use cheap and tiny lenses.
For a digital camera, the third important element is the processing/cleaning engine. This is a firmware that cleans up the digital image to remove "noise" (i.e. grain, hot pixels or dots). The drawback in using a strong cleaning engine is that it reduces the details of the photo. I imagine that if you set your camera to the "highest" photo quality, the cleaning engine is almost switched off.
The problem with setting the camera to take the highest quality image is that it can be prone to a lot of noise. Try setting your phone to take medium or low quality and see if its comparable to the relatively low quality noiseless photo by your Sharp phone.
The number of megapixels assures a bigger photo, but the size and quality of the lens is more important, and nowadays, its a race for a better cleaning engine.
If you want good quality photos, you need a more expensive phone (or better yet, a real camera).

How much difference in photo quality is there between a VGA (640x480) vs. a 1.3 megapixel camera phone?

For instance the Nokia 6103 vs. the Samsung SGH-D807
Answer
Usually different brands do give different image capturing quality even if they are the same megapixel.
I have found that samsung pictures are very good, even though im a nokia/sony man myself.
However, the 2 qualities you talk about would be almost unnoticable on the phone screen, however when it comes to printing the quality especially with increased size would be more sharp from the 1.3 MP.
www.mobile-review.com usually has photo samples of each phone, so then you can compare :-)
