Image processing program and image processing device for moving display area
First Claim
1. A non-transitory computer-readable storage medium having stored therein an image processing program to be executed by a computer of an image processing device, the image processing device comprising a pointing device capable of specifying a coordinate on a screen of a display device and configured to display on the screen a predetermined display area in a virtual space including a predetermined object, the display area comprising a portion of the virtual space to be displayed on the screen, the image processing program comprising instructions causing the computer to perform:
- determining whether coordinate specification by the pointing device has been performed; and
switching setting of the display area by executing, upon determining that the coordinate specification has been performed, a first setting in which the display area is set based on a position of the object and an input coordinate specified in the coordinate specification, and by executing, upon determining that the coordinate specification has not been performed, a second setting in which the display area is set based on the position of the object and the display area gradually moves automatically over a number of display frames toward the display area setting based on the position of the object.

Abstract
A video game device calculates a difference vector extending from a predetermined reference position on the screen to an input position. Moreover, the video game device calculates movement parameter data used for moving, with respect to a fixed point in the virtual space uniquely determined based on a position of the controlled object, the point of sight to a position that is determined by a direction in the virtual space based on a direction of the difference vector and a distance in the virtual space based on a magnitude of the difference vector. The point of sight is moved based on the movement parameter data. The video game device produces an image based on a virtual camera, which has been moved according to the movement of the point of sight, and displays the image on the screen of a display device.

10. An image processing device configured to display, on a screen of a display device, a predetermined display area in a virtual space including a predetermined object, the display area comprising a portion of the virtual space to be displayed on the screen, the image processing device comprising:
-
a pointing device capable of specifying a coordinate on a screen of the display device; and coordinate specification determining circuitry configured to determine whether coordinate specification by the pointing device has been performed; and display area switching circuitry configured to switch setting of the display area by setting, when the coordinate specification determining circuitry has determined that the coordinate specification has been performed, a display area based on a position of the object and an input coordinate specified in the coordinate specification, and by setting, when the coordinate specification determining circuitry has determined that the coordinate specification has not been performed, the display area based on the position of the object and gradually moving the display area automatically over a number of display frames toward the display area setting based on the position of the object. - View Dependent Claims (11)
