Abstract

An edit object is selected by displaying a plurality of edit objects such as figures or characters closely arranged or overlapped on a display screen. A pointer is used to specify a desired position on the main screen, and determine with a candidate selecting device whether or not a plurality of edit objects exists at a specified pointer position or in a predetermined region based on the specified position. If a plurality of edit objects exists, the edit objects existing at the position or in the predetermined region are selected as selective candidates. A subscreen is displayed on the display screen by a subscreen display device. The subscreen has a plurality of information regions which correspond to respective selective candidates. The pointer is moved on the subscreen, thus changing the display of the edit object on the main screen which corresponds to the information region indicated at the pointer position on the subscreen by highlighting or changing to a specific color. One of the information regions displayed on the subscreen is then specified by the input means.

if there exists a plurality of edit objects at said desired position or in a predetermined region based on said desired position, selecting edit objects at said desired position or in said predetermined region as selective candidates;

displaying a subscreen on said main screen, said subscreen comprised of a plurality of transparent tile-shaped information regions having only contour, respective ones of said information regions corresponding to respective ones of said selective candidates and wherein said information regions are provided in a number equal to those of said selected candidates;

moving a pointer on said subscreen by said input means;

changing a display of one of said edit objects on said main screen corresponding to one of said information regions indicated at said desired position on said subscreen, whereby an operator can recognize said corresponding one of said edit objects; and

specifying one of said information regions displayed on said subscreen by said input means, whereby one of said edit objects corresponding thereto is selected.

9. A method according to claim 8, wherein said subscreen is overlapped and displayed on said main screen.

10. A method according to claim 8, wherein said pointer can only move in said subscreen while said subscreen is displayed.

11. A method according to claim 10, wherein said subscreen comprises a pop-up menu.

12. A method according to claim 8, wherein a display of said one of said edit objects is changed on said main screen by highlighting the contour of said one of said edit objects.

13. A method according to claim 8, wherein a display of said one of said edit objects is changed on said main screen by changing a color of said one of said edit objects.

14. A method according to claim 8, wherein a size of said predetermined region varies with a magnification ratio of said main screen.

15. A method according to claim 8, wherein each of said information regions is a rectangle with the same shape.

16. A method for selecting one of a plurality of edit objects displayed on a display screen, comprising the steps of:

displaying a plurality of edit objects on a main screen of said display screen;

moving a pointer displayed on said main screen so as to specify a desired position on said main screen;

if there exists a plurality of edit objects at said desired position or in a predetermined region based on said desired position, selecting edit objects at said desired position or in said predetermined region as selective candidates;

displaying a subscreen on said main screen, said subscreen comprising an enlarged screen of a position of said pointer specified on said main screen or a predetermined region based on said position, a plurality of information regions being displayed in said subscreen, respective ones of said information regions corresponding to respective ones of said selective candidates;

moving a pointer on said subscreen by said input means;

changing a display of one of said edit objects on said main screen corresponding to one of said information regions indicated at said desired position on said subscreen, whereby an operator can visually recognize a corresponding one of said edit objects on said main screen; and

specifying one of said information regions displayed on said subscreen by said input means, whereby one of said edit objects corresponding thereto is selected.

17. A method according to claim 16, wherein said subscreen is overlapped and displayed on said main screen.

18. A method according to claim 16, wherein said pointer can only move in said subscreen while said subscreen is displayed.

19. A method according to claim 18, wherein said subscreen comprises a pop-up menu.
