An object of the present invention is to non-destructively obtain, in an X-ray imaging apparatus, a sectional image of a subject with spatial resolution higher than spatial resolution of an image detector. In the present invention, the image detector is two-dimensionally moved with respect to an incident X-ray for each half (180&#xb0;) rotation of the subject, and a plurality of image groups (CT data sets) is obtained at different positions of the image detector. An image (sinogram) is synthesized from each image group thus obtained, which image is equal to an image obtained with a detector whose pixel size is smaller than the pixel size constituting the above described image detector. From this synthesized image, a sectional image with high spatial resolution is calculated by reconstruction calculation.

Provided are an image encoding device that has high encoding efficiency, and an image decoding device. A mapping means maps pixel signals of an object to be encoded that are configured in prescribed color space to mapped pixel signals in which redundancy between the signals is reduced. The mapping coefficients are calculated from encoded pixel signals, thereby making encoding of mapping coefficients unnecessary. Furthermore, the mapping coefficients are calculated from pixel signals of an adjacent block comprising pixels similar to the pixels of the block to be encoded/decoded, thereby reducing redundancy significantly. The mapping is applied to the pixel signals of the block to be encoded/decoded and to an area of pixels to be referred to by prediction information, thereby enabling prediction to be applied to the mapped pixel signals, and, after executing transformation/quantization, encoding and inverse transformation/dequantization are executed. The mapped pixel signals are restored to the pixel signals.

The present invention provides an X-ray imaging system and method capable of performing time-resolved observation in a short measurement time at the same density resolution and in the same dynamic range as those for a diffraction enhanced X-ray imaging method, and also capable of observing a sample with high sensitivity even if the intensity of an incident X-ray varies with time. A refraction angle of X-ray beams caused by the sample is detected at a time by X-ray imagers by utilizing multiple X-ray diffractions by multiple analyzer crystals.

X-ray imaging system and method

Provided is a thin film stack inspection method capable of accurately measuring and inspecting layer thicknesses of thin film stacks. An X-ray having a long coherence length is used as an incident X-ray and the X-ray specular-reflected from a sample placed on a goniometer is partially bent by a prism. The X-ray bent by the prism and the X-ray going straight are made to interfere with each other to obtain interference patterns. Though being thin film stacks, the sample has a portion having no thin film and thus an exposed substrate. The X-ray not bent by the prism includes an X-ray specular-reflected from the exposed substrate. By changing the incident angle from 0.01&#xb0; to 1&#xb0;, the interference patterns of the specular-reflected X-ray are measured. Thus, layer thicknesses are measured using a change in a phase of the X-ray reflected from a film stack interface.

Audio features description method and audio video features description collection construction method

A variance between sequential video pictures is extracted, and then, a GOP boundary position is decided based on inter-frame variance information. Furthermore, simple motion estimation is carried out with respect to video pictures inside one GOP. If a motion variation between the video pictures is large, a small predictive frame interval is taken; to the contrary, if the motion variation is small, a large predictive frame interval is taken. The simple motion estimation is carried out between two downscaled feature planes at a timewise fixed interval with respect to a video picture which is discriminated to be an interlaced video picture, wherein a motion compensatory prediction error at that time is output as image variance information. If the image variance is small, coding is conducted by a frame structure; to the contrary, if the image variance is large, the coding is conducted by a field structure. With the above-described processing, it is possible to provide a video coding apparatus for deciding a GOP size and the predictive frame interval according to the feature of the input video picture, and another video coding apparatus for adaptively switching the coding by the frame/field structures according to the feature of the input video picture.
