Abstract:
An induced explosion of a firework ball is represented using a small processing volume. A range for an induced explosion is set around a firework ball to be exploded drawn on a display image, for example, as indicated by the broken line in FIG. 10A in accordance with attributes of the firework ball. A drawing range of each firework ball under management, the range being indicated by its attributes, is referred to, and any other firework ball drawn in the range is set as a firework ball to be exploded. As a result, the firework ball located around the exploded firework ball is also exploded as shown in FIG. 10B.
Abstract:
A dynamic image is decorated effectively with a small of processing volume. As shown in FIGS. 6A and 6B, images A that form a dynamic image representing a spreading firework are sequentially created in order in time in which the images appear in the dynamic image. On the currently created image shown in FIG. 6A, an image obtained by enlarging a spark portion of the image preceding the current image by a predetermined number is drawn in such a manner that it looks semi-transparent to obtain the image as shown in FIG. 6B.
Abstract:
A game device includes an input position acquiring unit and a first game control unit. The input position acquiring unit acquires a position of an entry provided by a player to a touch panel, which can concurrently detect entries at multiple points. The first game control unit displays objects and a sequence in which the objects should be erased on a screen image, and, in case that a position of an entry acquired is at a position corresponding to a position where an object to be erased next is displayed, erases the object from the screen image. The first game control unit includes: a single tap input control unit that, when an input on one object is acknowledged, erases the object; and a multiple-graphic-symbol-tap input control unit that, when inputs on multiple objects are acknowledged concurrently, erases those objects.
Abstract:
An image representing a motion of an object is obtained with a small processing volume. As shown in FIGS. 5A through 5G, positions in a three-dimensional space associated with sparks of a firework ball are sequentially calculated in accordance with motion characteristics of the sparks. Positions on a camera screen are obtained by projecting the calculated positions of the sparks at the current point in time in FIG. 5C, and a spark texture D is drawn in those positions. An image G representing a locus of each of the sparks is obtained by drawing a line segment connecting points that form a history of the points on the camera screen which are projections of points associated with each of the spark (points on a same radial line in FIG. 5F).

Abstract:
Images can be replayed from various viewpoints when games of various genres are replayed. When a game is replayed, a memory control unit holds only a certain replayable region with respect to a present camera viewpoint position successively in a RAM. If there is an instruction from a manual controller while the game is being replayed, a camera viewpoint moving unit moves the camera viewpoint position of a hypothetical camera on a given path corresponding to the instruction among a plurality of predetermined paths in the replayable region. The instruction from the manual controller can be entered interactively when the game is replayed.
