Image display device, image display method, and program
First Claim
1. An image display device, comprising:
- a display unit that displays an image and accepts a pressing operation on a display screen;
a memory; and
a controller that;
detects pressed coordinate positions on the display screen;
stores the detected pressed coordinate positions in the memory at a predetermined time interval and in a time sequence;
if, after a pressing on the display screen has been cancelled, the display screen is not pressed again before a predetermined pressing cancellation judging time passes, determines a cancellation of the pressing on the display screen;
sets a predetermined delay time based on the predetermined pressing cancellation judging time;
after the predetermined delay time has passed since the pressing on the display screen started, reads out the stored pressed coordinate positions at the predetermined time interval and in the time sequence; and
scrolls the image so as to follow a movement of the read-out pressed coordinate positions.

Abstract
An image display devices, methods, and programs that displays an image on a display screen. The devices, methods, and programs detect pressed coordinate positions on the display screen, store the detected pressed coordinate positions in a memory at a predetermined time interval in a time sequence, and if, after a pressing on the display screen has been cancelled, the display screen is not pressed again before a predetermined pressing cancellation judging time passes, determining a cancellation of the pressing on the display screen. The devices, methods, and programs set a predetermined delay time based on the predetermined pressing cancellation judging time, after the predetermined delay time has passed since the pressing on the display screen started, read out the stored pressed coordinate positions at the predetermined time interval and in the time sequence, and scroll the image so as to follow a movement of the read-out pressed coordinate positions.

6. An image display method, comprising:
-
displaying an image on a display screen; detecting pressed coordinate positions on the display screen; storing the detected pressed coordinate positions in a memory at a predetermined time interval and in a time sequence; if, after a pressing on the display screen has been cancelled, the display screen is not pressed again before a predetermined pressing cancellation judging time passes, determining a cancellation of the pressing on the display screen; setting a predetermined delay time based on the predetermined pressing cancellation judging time; after the predetermined delay time has passed since the pressing on the display screen started, reading out the stored pressed coordinate positions at the predetermined time interval and in the time sequence; and scrolling the image so as to follow a movement of the read-out pressed coordinate positions. - View Dependent Claims (7, 8, 9, 10)

11. A non-transitory storage medium storing a computer-executable image display program, the program comprising:
-
instructions for displaying an image on a display screen; instructions for detecting pressed coordinate positions on the display screen; instructions for storing the detected pressed coordinate positions in a memory at a predetermined time interval and in a time sequence; instructions for, if after a pressing on the display screen has been cancelled, the display screen is not pressed again before a predetermined pressing cancellation judging time passes, determining a cancellation of the pressing on the display screen; instructions for setting a predetermined delay time based on the predetermined pressing cancellation judging time; instructions for, after the predetermined delay time has passed since the pressing on the display screen started, reading out the stored pressed coordinate positions at the predetermined time interval and in the time sequence; and instructions for scrolling the image so as to follow a movement of the read-out pressed coordinate positions. - View Dependent Claims (12, 13, 14)
