Abstract:
1. An image processing apparatus that displays a moving image including an object image that represents a virtual object on a given display device, the image processing apparatus comprising: a first storage device in which first data that represents the object image is stored; a second storage device in which second data that represents the object image which is simplified more than the first data is stored; a first processor configured to receive and conduct geometry processing on the first data from the first storage device and on the second data from the second storage device and that conducts geometry processing of the object image by using one of the first data and the second data; and a second processor that generates one of images derived from the first data and images derived from the second data in accordance with results of the geometry processing, wherein the first processor determines data to be used in the geometry processing to one of the first data and the second data according to an attribute of the object image, wherein the second processor takes in the first data from the first storage device to generate the image derived from the first data when the data to be used in the geometry processing which is determined by the first processor is the first data, and takes in the second data from the second storage device to generate the image derived from the second data when the data to be used in the geometry processing which is determined by the first processor is the second data, wherein the second storage device can transfer data to the second processor faster than the first storage device, wherein the attribute of the object image is an apparent speed of the object image on a screen of the given display device, and wherein the first processor determines the data to be used in the geometry processing to the first data when the apparent speed of the object image on the screen is lower than a given speed, and determines the data to be used in the geometry processing to the second data when the apparent speed of the object image on the screen is higher than the given speed.
