    • 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.
    • 本文提供能够实时合成高质量图像的图像合成系统。 图像合成系统适于从场景中的最近多边形到视点处顺序地处理多个重叠多边形。 结束标志存储单元将结束标志存储在与处理的点对应的地址处。 处理点指令单元读出该结束标志,该结束标志又用于指示要处理到处理器单元的点。 在这种情况下,处理点指令单元指示处理器单元,使得决定处理的点的结束标志被写回结束标志存储单元,同时只处理待处理的点。 因此,图像合成可以顺序地执行到从最近的多边形开始到场景中的视点的多边形。 同时,可以省略对已处理的多边形的隐藏部分的计算处理。

    • 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.
    • 图像合成系统通过对物体的表面数据中的空间变化给出远近的感觉来改善图像的透视变换。 纹理数据存储单元将纹理数据存储在由纹理坐标表示的位置处。 图像供给单元输出纹理坐标,亮度数据,属性数据以及对应于多边形顶点坐标和顶点的其他数据。 处理器单元通过对纹理坐标和亮度数据进行透视变换,线性插值和反向透视变换来确定每个点的渲染数据。 然后将所得到的渲染数据映射到由场处理器在场缓冲器单元中确定的表示坐标。 此后,通过调色板/混合器电路,通过纹理坐标,属性数据和亮度数据从纹理数据存储单元读出的颜色数据将渲染数据变换为RGB数据。 因此,可以形成图像数据。

    • 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. A pressure controlling unit controls the interior of the vacuum-processing container at the desired pressure value in accordance with an output signal from which the error over time has been eliminated by the correcting unit.

    • 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.
