摘要:
A 4-line buffer sequentially takes in image data items and temporarily stores a specific size of image data. A spatial filter in which a coefficient matrix based on the no-neighbor algorithm in a restoration process has been set performs a spatial filtering process on the image data items sequentially outputted from the 4-line buffer to produce a restored image based on the no-neighbor algorithm. This enables images to be restored in real time, which produces an image whose luminance distribution is approximate to that of the specimen.

A composition which comprises a pyridinol derivative of the formula ##SPC1##Intimately dispersed in an inert edible carrier, wherein R.sub.1 and R.sub.2 may be the same or different and each represents a hydrogen atom; a lower alkyl group, an aralkyl group, an aliphatic, an aromatic or a heterocyclic acyl group; an alkoxycarbonyl group; an aralkoxycarbonyl group; an aryloxycarbonyl group; a N-substituted carbonyl group; a N-substituted thiocarbonyl group; a phosphono group; or a salt thereof.The composition is a preventive and curative anticoccidial agent for poultry and domestic animals. Particularly, it shows a significant activity against chronic coccidiosis caused by Eimeria acervulina.The composition is less toxic for animals, besides it has an advantage that it is also effective for coccidiosis caused by coccidia resistant to the known anticoccidial agents.

摘要:
An apparatus is for evaluating optical characteristics of an optical system based on an image forming position of a point image formed through the optical system. The apparatus includes a point image producing unit that forms a point image through the optical system in each point light source; an imaging unit that images the point images to produce a point image distribution image; and a moving unit that changes relative distance between the optical system and the point light source or the imaging unit in an optical axis direction. The apparatus also performs processing of detecting an image forming position in each different relative distance of the point image based on image information of the point image distribution images, the processing including calculating a regression expression for the detected image forming positions to obtain a shape parameter of the image axis in each of the point images.
