Display device, method and program
First Claim
1. A display device comprising:
- an acquisition unit configured to acquire coordinates on a display screen designated by a coordinate input apparatus;
a registering unit configured to register an enlargement target which is to be enlarged;
an enlargement processing unit configured to enlarge and display a partial area, which includes the enlargement target, if a positional relationship between coordinates acquired by said acquisition unit and a position at which the enlargement target, which has been registered by said registering unit, is displayed on the display screen satisfies a predetermined condition; and
a cancellation processing unit configured to cancel the enlarged display of the partial area by said enlargement processing unit based upon an input from the coordinate input apparatus,wherein said enlargement processing unit enlarges the partial area that includes the enlargement target if a moving speed of the coordinates acquired by said acquisition unit is within a prescribed range of speeds and distance between the acquired coordinates and the enlargement target is equal to or less than a prescribed distance.

10. A display processing method of a display device, the method comprising the steps of:
-
acquiring coordinates on a display screen designated by a coordinate input apparatus; registering an enlargement target which is to be enlarged; enlarging and displaying a partial area, which includes the enlargement target, if a positional relationship between coordinates acquired in said acquiring step and a position at which the enlargement target, which has been registered in said registering step, is displayed on the display screen satisfies a predetermined condition; and canceling the enlarged display of the partial area in said enlarging and displaying step based upon an input from the coordinate input apparatus, wherein said enlarging and displaying step enlarges the partial area that includes the enlargement target if a moving speed of the coordinates acquired in said acquiring step is within a prescribed range of speeds and distance between the acquired coordinates and the enlargement target is equal to or less than a prescribed distance.

11. A display processing program stored on a non-transitory computer-readable medium for causing a computer to function as:
-
an acquisition unit configured to acquire coordinates on a display screen designated by a coordinate input apparatus; a registering unit configured to register an enlargement target which is to be enlarged; an enlargement processing unit configured to enlarge and display a partial area, which includes the enlargement target, if a positional relationship between coordinates acquired by said acquisition unit and a position at which the enlargement target, which has been registered by said registering unit, is displayed on the display screen satisfies a predetermined condition; and a cancellation processing unit configured to cancel the enlarged display of the partial area by said enlargement processing unit based upon an input from the coordinate input apparatus, wherein said enlargement processing unit enlarges the partial area that includes the enlargement target if a moving speed of the coordinates acquired by said acquisition unit is within a prescribed range of speeds and distance between the acquired coordinates and the enlargement target is equal to or less than a prescribed distance.
