Visual field changing method
First Claim
1. A visual field changing method comprising, in an image display system having functions of displaying image data in a display window, determining a position of a pointer in the display window by using an operation input part, and receiving a visual field changing instruction from a user and changing a display of the image data based on the visual field changing instruction:
- displaying one or a plurality of visual field changing start region associated with a visual field changing operation, which defines display update processing contents of the image data, in the display window;
determining whether or not the pointer is in the visual field changing start region;
activating the visual field changing operation associated with the visual field changing start region when the pointer enters the visual field changing start region;
while the visual field changing operation is being activated, detecting a relative movement amount of the pointer based on the position of the pointer at a time when the visual field changing operation is activated, and updating the display of the image data in accordance with the display update processing contents defined by the activated visual field changing operation, based on the detected relative movement amount of the pointer;
determining whether or not a predetermined condition for deactivating the visual field changing operation is satisfied; and
in a case where the predetermined condition for deactivating the visual field changing operation is satisfied, deactivating the visual field changing operation.

Abstract
In an image display system for changing a display of image data based on a visual field changing instruction, one or a plurality of visual field changing start region associated with a visual field changing operation, which defines display update processing contents of the image data, is displayed in a display window. When a pointer enters the visual field changing start region, the visual field changing operation associated with the visual field changing start region is activated, and the display of the image data is updated in accordance with the display update processing contents defined by the activated visual field changing operation, based on a relative movement amount of the pointer based on the position of the pointer at a time when the visual field changing operation has been activated. In the case where the pointer is moved to outside of the visual field changing start region corresponding to the activated visual field changing operation and is placed in the display window, the visual field changing operation is deactivated.

10. A visual field changing method comprising, in an image display system having functions of displaying image data in a display window, determining a position of a pointer in the display window by using an operation input part, and receiving a visual field changing instruction from a user and changing a display of the image data based on the visual field changing instruction:
-
detecting a selecting operation in the operation input part;
in a case where the pointer is in the display window, dividing the display window into two regions of a central region of the display window and a region outside of the central region of the display window, and determining in which region the pointer is placed;
in a case where it is determined that the pointer is placed in the region outside of the central region of the display window when the selecting operation is detected, updating the display of the image data so that a display object displayed at a position of the pointer is moved to a center of the display window; and
in a case where it is determined that the pointer is placed in the central region of the display window when the selecting operation is detected, updating the display of the image data so that the display object displayed at the position of the pointer is moved to the center of the display window and displayed in an enlarged state at a predetermined factor. - View Dependent Claims (11)

14. A visual field changing method comprising, in an image display system having functions of displaying image data in a display window, determining a position of a pointer in the display window by using an operation input part, and receiving a visual field changing instruction from a user and changing a display of the image data based on the visual field changing instruction:
-
selecting one of display objects as a representative object;
detecting a selecting operation in the operation input part;
determining which display object the pointer points in the display window when the selecting operation is detected;
in a case where the display object determined to be pointed by the pointer is a representative object, updating a display of the image data so that a point pointed on the display object is displayed at a center of the display window; and
in a case where the display object determined to be pointed by the pointer is not a representative object, updating a display of the image data so that the entire display object is displayed with a predetermined size in the display window.

-
displaying one or a plurality of visual field changing start region associated with a visual field changing operation, which defines display update processing contents of the image data, in the display window;
determining whether or not the pointer is in the visual field changing start region;
activating the visual field changing operation associated with the visual field changing start region when the pointer enters the visual field changing start region;
while the visual field changing operation is being activated, detecting a relative movement amount of the pointer based on the position of the pointer at a time when the visual field changing operation is activated, and updating the display of the image data in accordance with the display update processing contents defined by the activated visual field changing operation, based on the detected relative movement amount of the pointer;
determining whether or not a predetermined condition for deactivating the visual field changing operation is satisfied; and
in a case where the predetermined condition for deactivating the visual field changing operation is satisfied, deactivating the visual field changing operation.
