Abstract
An image processing method whereby an image of object generated in real time in a pre-generated background image by giving operators an impression of depth or distance can be synthesized and a storage medium for storing the image processing program are provided. In the present invention, image data of a pre-generated image, such as a background image, includes image data, which is texture data or color data, and Z data indicating a depth in a screen. Then, the data of the pre-generated image like a background image is recorded on a storage medium in advance. The Z data of real timely generated image is compared with the Z data of the background image, and the image data, which is foremost in the screen, is written in a frame buffer. It becomes possible to synthesize the image of real timely generated object in the background image with giving an impression of depth or distance by adding the Z data to the data of pre-generated image.
