Abstract: 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).

Abstract: 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.

Abstract: When images are repeatedly recorded on a recording medium such as a single sheet of paper, the length of the second image to be recorded is varied dependent on the shrinkage factor of the recording medium which is derived from the period of time in which the recording medium is left from the time when the recording of the first image is completed to the time when the second image starts to be recorded. Positional deviation or size difference between the images which would otherwise be caused by the shrinkage of the recording medium upon repetitive image recording can be eliminated.
