There’s considerabl echatter with reference to megapixels all over the internet. I’ve taken a part in it myself: “The iPhone 4 coming in at 5 megapixels. The Droid X boasting an spectacular statistic of eight megapixels." It sounds good, but do you know what this really means?
Pixel, without a doubt, means exactly what it says; in essence a incredibly small space of screen real estate. The multitude of of pixels a camera offers is what decides what resolution the photograph is. Mega, in this case, means million. Combine the two definitions, and what do you get: One million pixels.
Some people get taken in by these stats, but numerous individuals don’t realize that they are talking about a still camera when they tout these statistics; not a video camera. The video would be the LED flash or VGA part of the camera.
So, as an example, the iPhone 4's 5 megapixel camera would take pictures in a resoltuion of 3303 x 2477. 8 megapixel camera phones such as the Droid X take photographs in an amazing resolution of 5285 x 3963 (wow!).
I don’t take many photos (I’m more for videos), so I pay much more attention to the quality of the LED Flash or VGA video cameras on a phone. However, I'd venture to say that most people still prefer a good photo over a video.
Of course, the amount of pixels in a photo isn't the only thing to consider in a camera's quality. Very important, as well, are the options a phone has on taking a photo (the iPhone 4 camera can zoom in up to 5 times, for example).
There is also a place where it really doesn't matter. Because the resolution of these photos are so high now, the resolution makes little difference in the quality of photos on screens with pixels less than 3 million, and almost no computer screen has that. If you’re looking to display it on a big TV (or one of those uncommon 42 inch computer monitors), though, the difference is frequently very substanial.
So hopefully this has assisted to clear up what megapixels means, and has provided to you additional information to be sure to make the correct choice in the smartphone to get.
