Patent number: 6333747Abstract: An image synthesizing system is provided which can output a high-quality image in real time through the texture mapping without preventing the hardware from being increased in speed and reduced in scale. A 3-D image is formed by a game space processing unit (13) and image supply unit (10) to perform a 3-D computation. At a processor unit (30), coordinates for each dot in a polygon and the corresponding texture coordinates are determined. A field buffer unit (40) stores the texture coordinates at an address specified by the coordinates for each dot. A texture data storage unit (42) has stored a rendering data. The texture coordinates are read out from the field buffer unit (40) and then used to read out the rendering data from the texture coordinate storage unit (42) to synthesize and output a pseudo 3-D image. By thus storing the texture coordinates in the field buffer unit (40), the subsampling/interpolation and the like may be carried out.Type: GrantFiled: November 5, 1998Date of Patent: December 25, 2001Assignee: Namco Ltd.Inventors: Hiroyuki Murata, Takashi Yokota, Katsuhiro Miura

Publication number: 20010032174Abstract: A network transacting method uses a data processing system in which terminal units are interconnected via a communication network for interchanging data with each other. A trader presents data representative of an industrial or an intellectual property purchase offer in the form of, e.g., a homepage, which can be freely browsed via the communication network. When the trader desires to purchase an industrial or an intellectual property from a seller, the trader accesses a search server installed in a Patent Office to see if the property and seller are licit. On purchasing the intellectual property, the trader applies for the registration of the property at the Patent Office and then presents the purchased property to a buyer. In addition, the trader takes proceedings for the transfer of the property at the Patent Office. The method promotes a broad range of industrial property and intellectual property transactions while freeing sellers and buyers from troublesome legal procedures.Type: ApplicationFiled: April 16, 2001Publication date: October 18, 2001Inventor: Takashi Yokota

Patent number: 5615322Abstract: An image synthesizing system capable of synthesizing a high-quality image in real time is provided herein. The image synthesizing system is adapted to process a plurality of overlapping polygons sequentially starting from the closest polygon to the view point in a scene. An end flag storage unit stores an end flag at an address corresponding to the processed dot. A processing dot instruction unit reads out this end flag which in turn is used to indicate a dot to be processed to a processor unit. In such a case, the processing dot instruction unit instructs the processor unit so that the end flag of the dot decided to be processed is written back into the end flag storage unit while at the same time only the dot to be processed is treated. Thus, the image synthesization can sequentially be carried out to the polygons starting from the closest polygon to the view point in the scene. At the same time, the computing process to the hidden portion of polygons which have been processed can be omitted.Type: GrantFiled: December 28, 1994Date of Patent: March 25, 1997Assignee: Namco Ltd.Inventors: Hiroyuki Murata, Takashi Yokota

Patent number: 5561746Abstract: An image synthesizing system improves perspective transformation of images by giving a far and near sense to the spatial change in the surface data of an object. A texture data storage unit stores texture data at positions represented by texture coordinates. An image supply unit outputs texture coordinates, brightness data, attribute data and the other data which correspond to the vertex coordinates arid vertices of polygons. A processor unit determines rendering data for each dot by subjecting the texture coordinates and brightness data to the perspective transformation, linear interpolation and inversely perspective transformation. The resulting rendering data is then mapped to representing coordinates determined by a main processor in a field buffer unit. Thereafter, the rendering data is transformed into RGB data by a palette/mixer circuit using color data which are read out from a texture data storage unit by the texture coordinates, attribute data and brightness data. Thus, an image data can be formed.Type: GrantFiled: August 26, 1993Date of Patent: October 1, 1996Assignee: Namco Ltd.Inventors: Hiroyuki Murata, Takashi Yokota

Patent number: 5553208Abstract: An image synthesizing system is provided which can increase the speed of its hardware and reduce the scale of the same by using the subsampling/interpolation. A processor unit (80) determines coordinates of each dot and associated texture coordinates in polygons based on image data of vertices. A field buffer unit (40) stores the texture coordinates at its address specified by the coordinates of each dot. The texture coordinates are read out from the field buffer unit (40) and then used to read out rendering data from a texture data storage unit (42) to synthesize and output a pseudo 3-D image. In this case, the processor unit (30) includes a subsampling unit. Texture coordinates of the dots ignored by the subsampling unit are determined on the texture coordinates of dots adjacent to the ignored dots through interpolation circuits (180)-(186).Type: GrantFiled: April 1, 1994Date of Patent: September 3, 1996Assignee: Namco Ltd.Inventors: Hiroyuki Murata, Takashi Yokota

Patent number: 5311452Abstract: A pressure gage detects a pressure in a vacuum-processing container as an electrical signal. A pressure detection signal from the pressure gage includes an error over time. An error detecting unit detects a signal representing the error which is output from the pressure gage while the vacuum-processing container is set at a predetermined calibration pressure. A correction value calculating unit calculates, in accordance with the signal representing the error which is detected by the error detecting unit, a signal representing a correction value used in order to cancel the signal representing the error. A correcting unit adds the pressure detection signal from the pressure gage to the signal representing the correction value which is calculated by the correction value calculating unit while an instruction for setting an interior of the vacuum-processing container at a desired pressure value is output, thereby eliminating the error over time which is included in the pressure detection signal.Type: GrantFiled: November 27, 1991Date of Patent: May 10, 1994Assignee: Tokyo Electron LimitedInventors: Takashi Yokota, Osamu Kamikanda
