Recently I opted to buy a camera from Smifu . I asked my Bro a suggestion regarding my purchase, suddenly he started to ask me number of questions about cameras and I was able to answer all the questions , but except this one. Does anyone know what this means ? I checked most of the camera forum, review sites etc. But I was not able to find the answer .(Actually I may know the answer but I was not able to understand my bro question, when I asked about this to him , he said the answer is in the question itself) . Please let me know the answer for this !

Please clarify your specific problem or add additional details to highlight exactly what you need. As it's currently written, it’s hard to tell exactly what you're asking.If this question can be reworded to fit the rules in the help center, please edit the question.
The answer is simple: "Not a big deal".
It's obviously technically right to say "three megapixels, give or take", but by itself that overstates the importance. 19 megapixels isn't automatically 18.7% better — in fact, the real resolution may actually be worse in the real world, as there are so many other factors.
It's hard to read minds, but I suspect this is what your "bro" was getting at.
I thought one of two things:
A. The camera has two aspect ratios and has a different pixel count for each' one of the two not using the entire sensor.
B. the sensor size is 19mp but the images made are 16mp due to internal cropping. I had an old Sony mini DV that did this to handle motion, vs. a lens based image stabilization.
