The object is to increase the efficiency of processing by conferring the residual image function on hardware and to provide an image processing device wherein processing is implemented at higher speed. In an image processing device equipped with an image memory and a control section that writes generated image data to the image memory, there is provided a blend circuit that reads image memory or image data from image memory and attenuates the read image data and that writes this together with newly generated image data into another image memory, thereby producing a residual image effect.

Image processing device and image processing method

A transparency conversion circuit 40 is provided between a matrix conversion circuit 4 and an intensity calculation circuit 5 in a geometry processing unit 20. The transparency conversion circuit 40 is provided with a converter 41 and a parameter register 42. The converter 41 converts the transparency at the vertex that is input by the matrix conversion circuit 4 in correspondence to the Z component of the unit normal vector at the vertex, and the results are output to the intensity calculation circuit 5. The parameter register 42 holds a parameter value that is used for the conversion performed by the converter 41. As a result, the transparency at a polygon can be corrected while taking into consideration the angle formed by the planar surface of the polygon and the direction of the line-of-sight and the environment in which the polygon is placed. Therefore, a method for and an apparatus for transparency conversion whereby a translucent polygon is rendered to produce an impression of solidity are provided.

Method for and apparatus for transparency conversion, image processing

The present invention relates to a image processing apparatus and the method thereof which can change image to be shown on a reflection surface of an object. The image processing apparatus for generating image data to be displayed on a predetermined display screen, comprises: a processor for performing a filling process of filling a polygon to generate image data based on positional information of said polygon on two-dimensional coordinates corresponding to said display screen and texture data associated with said polygon; a frame buffer memory for storing the image data corresponding to said display screen; and a reflection map memory for storing image data to be shown on a reflection surface in said display screen, wherein said processor generates said image data to be shown on said reflection surface based on viewpoint information corresponding to said reflection surface and positional information of a polygon which lies in said reflection surface, stores said generated image data in said reflection map memory, and further generates said image data to be displayed on said display screen based on viewpoint information corresponding to the display screen, positional information of a polygon which lies in said display screen, and said image data in said reflection map memory.
