  A method of determining the area for image capturing by moving a fixed size frame window independently from the mouse pointer

Disclosed is an easy method to determine the selection area for capturing an image.
By moving a fixed size frame window independently from the mouse pointer, users can
easily shift/select the area to be captured.

This method consists of the three steps described below:

(1). Show the fixed size frame window.
The size of this window is adjustable by drag and drop operation or by inputting
its size in pixels.

(2). When the pointing device is moved in combination with another key such as a
mouse button, Ctrl or Shift key, the frame window is moved independently of the
mouse pointer on the screen. This technique provides several advantages:

User does not need to "grab" the frame window with the pointer and use a
combination key which is required by standard "drag-and-drop"
implementations of similar features.

The capture frame window is more intuitive and requires less effort - much
like the view frame in a camera.

Because it is independent of the mouse pointer, the "gain" (input:output) of
the transfer function can be increased compared to mouse pointer so that the
the frame window can be moved with finer control. Thus it is easier for the
user to smoothly move "pixel by pixel" to get the exact data desired for the
capture.

(3). When the users select "Copy", capture the image inside the frame window.
