Abstract

The present invention relates to an interactive image and graphic system and method capable of detecting collision. A storage device stores a plurality of image data streams. Each image data stream includes a header, which has at least one position coordinate field, and the at least one position coordinate field corresponds to at least one object of the image data stream. An image engine plays a first image data stream of the plurality of image data streams. A graphic engine receives a sprite picture data. The sprite picture data includes a sprite position coordinate. The graphic engine receives the header of the first image data stream. When the sprite position coordinate superimposes over a position coordinate of the at least one object of the first image data stream, the graphic engine drives the image engine to select a second image data stream from the storage device for being played.

Dependent claims

An interactive image and graphic system capable of detecting collision, comprising:

a storage device, storing a plurality of MPEG4 image data streams, each said MPEG4 image data stream including a header, wherein the header having at least one position coordinate field corresponding to at least one object of the MPEG4 image data stream, and the at least one position coordinate field is recorded with a left-top coordinate position (x1, y1) and a right-bottom (x2, y2) coordinate position of the at least one object;
an image engine, coupled to the storage device, for playing a first MPEG4 image data stream of the plurality of MPEG4 image data streams;
and
a graphic engine, coupled to the storage device and the image engine, for receiving a header of the first MPEG4 image data stream and receiving a sprite picture data having a sprite position coordinate (x3, y3), wherein when the sprite position coordinate superimposes over a position coordinate of the at least one object from the first image data stream by means of two determinations x1≦x3≦x2 and y1≦y3≦y2, the graphic engine determines that there is a collision generated between the sprite picture and a picture of the at least one object and thus drives the image engine to select a second MPEG4 image data stream from the storage device for being played, and when the sprite position coordinate does not superimpose over the position coordinate of the at least one object from the first MPEG4 image data stream, the graphic engine drives the image engine to continuously play the first MPEG4 image data stream, or to select a third MPEG4 image data stream from the storage device for being played after a predetermined time interval.

A method for detecting collision in an interactive image and graphic system, the image and graphic system having an image engine and a graphic engine, the graphic engine receiving a sprite picture data having a sprite position coordinate (x3, y3), the image engine receiving one of a plurality of MPEG4 image data streams, the MPEG4 image data stream including a header having at least one position coordinate field corresponding to at least one object of the MPEG4 image data stream, and the at least one position coordinate field is recorded with a left-top coordinate position (x1, y1) and a right-bottom (x2, y2) coordinate position of the at least one object, the method comprising the steps of:

(A) the graphic engine and the image engine respectively playing the sprite picture data and a first MPEG4 image data stream;
(B) the graphic engine receiving a header of the first MPEG4 image data stream;
and
(C) when the graphic engine determines that the sprite position coordinate superimposes over a position coordinate of the at least one object of the first MPEG4 image data stream and thus determines that there is a collision generated between the sprite picture and a picture of the at least one object by means of two determinations x1≦x3≦x2 and y1≦y3≦y2, the graphic engine driving the image engine to select a second MPEG4 image data stream from the storage device for being played.
