For Photoshop, this is adjustable, in the toolbar.  You can set the
eyedropper to sample a single pixel, or the average of a 3x3 or 5x5 matrix
of samples around the click point.

In any case, this feature has nothing to do with how a scanner samples raw
data.  It is simply a design choice for one feature of the user interface in
an image editing program.
