  • Patent number: 6749509
    Abstract: An image processing method and apparatus is provided which is capable of reducing the load to be processed and displaying a more realistic picture. The image processing device includes camera control matrix processing means (121), object matrix processing means (122), and object pattern display means (123). The camera control matrix processing means (121) obtains a matrix of information on the position, etc. of a camera on the basis of control information from the control unit 20 and stores it in a data RAM (104). The object matrix processing means (122) fetches the matrix of information on the camera stored in the data RAM (104), performs coordinate conversion of the matrix of information with the aid of a conversion matrix, and sets rotational components of the coordinate-converted matrix so as to compose a unit matrix thereby creating display data which causes an object such as an explosion pattern to face in an eye direction at all times.
