Abstract: Molecules of a specific species can be selectively excited among molecules of a plurality of species that show only a slight difference of mass. Energy levels can be displayed on a graph where the horizontal axis indicates excitation energy. Assume an instance where an electromagnetic wave showing a comb-shaped spectrum having a plurality of narrow bands as indicated by P1 through P14 and tuning with excitation energies corresponding to the rotational levels of molecule X is irradiated onto the molecule X. The molecule X can sequentially make transitions to higher energy levels by using an electromagnetic wave showing such a comb-shaped spectrum. The energy levels of molecule Y are not synchronized with the comb-shaped spectrum. The two ranges of Y4 through Y7 and Y12 through Y15 operate as gates and the molecule Y cannot make transition from a rotational level to another when a gate is found between them.

Abstract: In connection with the detection of an amount of movement of an image such as a document image having a small gradient of brightness, it has been difficult to detect the amount by a representative point method, and a block matching method requires much time. An image (F1) at a time (T1), which has been imaged by moving an imaging section (1), is taken into a memory (2) and a feature point extracting section (3), where feature points of the image (F1) are extracted, and an image (F2) at a start time (T2) of the subsequent frame is taken in the memory (2) and the feature point extracting section (3). A correlation operating section (5) operates feature points of the image (F2) and the image (F1) in an area designated by a search area deciding section (4) to output an amount of movement.

Abstract: In the case where an image of a document or the like is taken by an economical camera in a TV conference system and the image is transmitted and received through a communication line, when an image of the whole of the document is taken, small characters are defaced and illegible, and, when an imaging operation is performed with a resolution at which characters are readable, it is impossible to take an image of the whole of the document. An image F1 at time T1 which is taken while moving an imaging section is captured into an image storing section and a feature point extracting section. The feature point extracting section extracts feature points of the image F1. An image F2 at time T2 when the subsequent frame is started is captured into the image storing section and the feature point extracting section.

Abstract: A one-dimensional image synthesizing unit 3 images an subject, and produces a plurality of image-to-be-combined signals expressing images-to-be-combined having overlapped regions. A central processing unit 5 first obtains matching of images of the subject for each of adjacent images-to-be-combined for all image-to-be-combined signals by center and large block matching processes, and detects the deviations of overlapped regions from the obtained matching. Next, in a small block matching process, on the basis of the deviations of the overlapped regions, a plurality of reference blocks and search regions are made to correspond to each other and are set in the respective overlapped regions, and the deviations of the images of the subject are detected in a unit of each search region in more detail than the deviations detected by the large block matching process.

Abstract: A picture processing apparatus which can reduce matching errors and shorten a processing time for matching. In the picture processing apparatus, a binarization circuit individually binarizes a pair of object picture signals to generate line picture signals. A feature point extract circuit extracts a plurality of feature point pixels for each reference area in the reference side line picture. A transforming circuit widens a line width of the search side line picture. A correlation computation circuit, for each reference area, finds a correlation between each pixel within a search area in the line picture whose line width has been widened and the feature point pixels. A composition processing section composites the pair of object picture signals based on the correlations. A picture processing apparatus which can adjust density and color tone of two pictures to be composited.
