Abstract

A covered image projecting method for a portable electronic apparatus is disclosed. The method comprises the follow steps: displaying an input area in a display field; determining whether a position of an input cursor in the display field is covered by the input area; if the position of the input cursor in the display field is covered by the input area, capturing a local area image around the position of the input cursor; and projecting the local area image in the display field.

Claims

1. A covered image projecting method for a portable electronic apparatus, the method comprising the following steps:

displaying an input area in a display field;

determining whether a position of an input cursor in the display field is covered by the input area;

if the position of the input cursor in the display field is covered by the input area, capturing a local area image around the position of the input cursor; and

projecting the local area image in the display field.

2. The method as claimed in claim 1, wherein the local area image is centered on the position of the input cursor.

3. The method as claimed in claim 2, wherein the local area image changes when the position of the input cursor moves.

4. The method as claimed in claim 1, wherein the local area image is turned off when the input area is turned off or the input cursor disappears.

5. The method as claimed in claim 1, wherein when it is determined that the position of the input cursor is not covered by the input area, the local area image is turned off.

6. The method as claimed in claim 1 further comprising the following steps:

determining whether a remaining area other than the input area exists in the display field;

if the remaining area exists in the display field, determining whether the remaining area contains sufficient space for projection; and

if the remaining area contains sufficient space for projection, choosing a suitable projection position for projecting the local area image.

7. A portable electronic apparatus comprising:

a display module for displaying a display field;

a field detecting module for determining whether a position of an input cursor in the display field is covered by an enabled input area;

a field capturing module for capturing a local area image around the position of the input cursor when the position of the input cursor is covered by the input area; and

a field projecting module for projecting the local area image in the display field.

8. The portable electronic apparatus as claimed in claim 7, wherein the local area image is centered on the position of the input cursor.

9. The portable electronic apparatus as claimed in claim 7, wherein the field capturing module captures the local area image again when the position of the input cursor moves.

10. The portable electronic apparatus as claimed in claim 7, wherein the field projecting module turns off the local area image when the input area is turned off or the input cursor disappears.

11. The portable electronic apparatus as claimed in claim 7, wherein when the field detecting module determines that the position of the input cursor is not covered by the input area, the field projecting module is notified to turn off the local area image.

12. The portable electronic apparatus as claimed in claim 7, wherein the field detecting module determines whether a remaining area other than the input area exists in the display field;

if the remaining area exists in the display field, the field detecting module chooses a suitable projection position in the remaining area for projecting the local area image when the field detecting module determines the remaining area contains sufficient space for projection.
