To provide an inspection device capable of imaging a transmission image while changing relative positions of a radiation source, an inspection object, and a detector. An inspection device comprises a radiation generator, a substrate holding unit for holding an inspection object, a detector, a substrate holding unit driving unit and a detector driving unit, a substrate position detection unit and a detector position detection unit, and a control unit, wherein the control unit executes a step for causing the detector to start acquiring an image while the relative positions of the radiation generator, the substrate holding unit and the detector are changing, a step for acquiring information relating to the positions of the substrate holding unit and the detector when the detector starts acquiring an image, and a step for storing the image acquired by the detector and the information relating to the position in association with each other.

Inspection device

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 (,) and image supply unit (,) to perform a 3-D computation. At a processor unit (,), coordinates for each dot in a polygon and the corresponding texture coordinates are determined. A field buffer unit (,) stores the texture coordinates at an address specified by the coordinates for each dot. A texture data storage unit (,) has stored a rendering data. The texture coordinates are read out from the field buffer unit (,) and then used to read out the rendering data from the texture coordinate storage unit (,) to synthesize and output a pseudo 3-D image. By thus storing the texture coordinates in the field buffer unit (,), the subsampling/interpolation and the like may be carried out.

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.

Image synthesizing system

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.

Image synthesizing system for producing three-dimensional images

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.
