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 ( ), object matrix processing means ( ), and object pattern display means ( ). The camera control matrix processing means ( ) obtains a matrix of information on the position, etc. of a camera on the basis of control information from the control unit and stores it in a data RAM ( ). The object matrix processing means ( ) fetches the matrix of information on the camera stored in the data RAM ( ), 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.
