<p><P>PROBLEM TO BE SOLVED: To provide a control device and method for controlling a cursor on an image display device by two methods by a switching mechanism, and an image system. <P>SOLUTION: This cursor control device 3 for an image display includes a first sensing unit 30, a second sensing unit 31 and a switching device 32. The first sensing unit 30 is for detecting a first displacement of the cursor control device 3 with respect to a surface and calculating a first coordinate variation of the cursor on the image display 2 according to the first displacement. The second sensing unit 31 is for detecting an object, detecting a second displacement of the cursor control device 3 with respect to the object and calculating a second coordinate variation of the cursor on the image display 2 according to the second displacement. The switching device 32 switches the first coordinate variation and the second coordinate variation and makes an output. The present invention further provides a cursor control method for an image display and an image system. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
