Abstract:
1. An image generating apparatus comprising: a first data storage unit for storing a plurality of vector graphics data segments; a second data storage unit for storing operation information defining a plurality of types of display operation patterns for any one of the vector graphics data segments in units of frames by using transformation matrices; a third data storage unit for storing a plurality of picture-plane configuration information items which identifies a vector graphics data segment to be displayed in a display plane, out of the plurality of vector graphics data segments, and also identifies a display operation pattern to be assigned to the vector graphics data segment to be displayed, out of the plurality of types of display operation patterns; an image generation unit for obtaining a graphics data segment from the first data storage unit, in accordance with the picture-plane configuration information item specified out of the plurality of picture-plane configuration information items, obtaining a display operation pattern to be applied to the obtained vector graphics data segment from the third data storage unit, and generating animated images of the obtained vector graphics data segment in accordance with the obtained vector graphics data segment and the obtained display operation pattern; and a memory having first and second storage regions, the image generation unit including: an animation data generation unit for generating animation data including the obtained vector graphics data segment and display control data corresponding to the obtained vector graphics data segment, on the basis of the obtained vector graphics data segment and the obtained display operation pattern; a list generation unit for generating picture-plane display lists, each picture-plane display list defining a drawing position of each of the vector graphics data segments in the display plane; a drawing unit for generating the animated images by decoding the vector graphics data segments in accordance with the animation data; and a control unit, wherein: the picture-plane display lists and the animation data are stored in the memory; the drawing unit generates the animated images in accordance with the picture-plane display lists and the animation data stored in the memory; one of the first and second storage regions is used as a region where one of the picture-plane display lists and the animation data for a current display plane are stored; the other of the first and second storage regions is used as a region where another one of the picture-plane display lists and the animation data for a next display plane are stored; and the control unit copies existing animation data in said one of the first and second storage regions onto the other of the first and second storage regions, without having the animation data generation unit generate the same animation data as the existing animation data stored in said one of the first and second storage regions among the animation data to be generated for the next display plane.
