When talking about digital cameras, resolution refers to the number of megapixelsproduced by an image sensor. This, in turn, generally corresponds to the amount of detail a camera can capture. So if your camera packs 20 megapixels (often written as 20 MP), it captures less detail than a camera with 30 megapixels, which in turn captures less detail ...
Technically, a megapixel is equal to 1,048,576 pixels; in reality, camera manufacturers round this number to 1,000,000 when stating how large of an image the camera will capture. So my camera, for example, captures 14.6-megapixel images, which is around 14,600,000 pixels per image (14.6 x 1,000,000). This information tells you nothing about the act...
Technically, a megapixel is equal to 1,048,576 pixels; in reality, camera manufacturers round this number to 1,000,000 when stating how large of an image the camera will capture. So my camera, for example, captures 14.6-megapixel images, which is around 14,600,000 pixels per image (14.6 x 1,000,000).
This information tells you nothing about the actual pixel dimensions of the image – it only tells you the total number of pixels that make up the image. My camera, like most DSLRs, captures images with an aspect ratio of 1.5. So the ratio comparing the number of pixels along the long edge of the image to the short edge of the image is 3:2.
This, in turn, generally corresponds to the amount of detail a camera can capture. So if your camera packs 20 megapixels (often written as 20 MP), it captures less detail than a camera with 30 megapixels, which in turn captures less detail than a camera with 40 megapixels. But what is a megapixel, really?
Again, camera megapixels and aspect ratio are said as nominal rounded values. But these two values are just a multiplication and a division of the pixel dimensions, and as explanation of the precision offered, the second Image Size option was added to show those actual more precise computed values.
