The megapixel myth
6mpixel.org reports: [edited]
A digital camera with 12 million pixels is better than one with 6 million. ‘That is correct’ is what you would probably say because you’ve always heard more pixels are better.
It’s not true, we have to say when it comes to compact cameras. We, the staff of Image Engineering which is an independent testing laboratory that, amongst other things, tests digital camera for the German magazines Color Photo and c’t. Quite a while ago we noticed that the image quality of digital cameras was getting worse instead of better. The reason is that today’s sensors are divided into more and therefore smaller pixels. We want to clarify the consequences on this website.
The reason we bring this up is the vicious circle we are in and have to break out of. Most people have heard that a lot of pixels make a good camera hence they buy the cameras with the most pixels. Thus, manufacturers produce cameras with more and more pixels so that they will sell better. But this does not improve the quality of the pictures.
6 megapixels is the best compromise between number of pixels and image noise (using the current size of compact camera CCD).
