Abstract
A cursor control method, for moving a cursor on a first displayed image and a second displayed image, comprising: (a) receiving a first displacement value when the cursor is within a first region of the first displayed image and receiving a second displacement value when the cursor is within a second region of the first displayed image; (b) moving the cursor with a first moving value on the first displayed image, which is obtained from the first displacement value and a first ratio; and (d) moving the cursor with a second moving value on the second displayed image, which is obtained from the second displacement value and a second ratio; wherein the first ratio is different from the second ratio; wherein the second displayed image is a zoom out and partial image of the first displayed image. By this way, the cursor movement accuracy can be increased.
