Using this standard, can we capture images using document scanners? If yes,
what capture parameter we need to give? Similarly if we need to capture
images of finger prints, palm prints and iris images using live scanner
devices, what will be the capture parameter? Will it be camera?

So the distinction between the two is that using the 'capture' attribute
indicates that a live capture is preferred?

In that case, I suggest that the 'capture' attribute be a boolean, leaving
the type-checking to the 'accept' attribute, which already serves this
function.

Not only would this avoid duplication, it also avoids conflicts like

   <input capture=microphone accept='image/*'>
