    摘要: An image encoding method, and an apparatus therefor, enabling rapid comprehension of the outline of the entire image promptly, at the decoding of the encoded image information, and also an image encoding method, and an apparatus therefor, capable of efficient encoding adapted for the state of the image to be encoded. Image information is divided into plural block, each consisting of plural pixels, the frequency of the image in each block is analyzed, the frequency components of the image in each block are separated into plural bands, and the frequency components contained in each of said plural bands are encoded.

    摘要: An image reducing apparatus for obtaining a reduced image from an image of an original size has: a filter to execute a filtering process to the image of the original size every image block of a predetermined size; a discriminating circuit to discriminate a structure of the image block filter processed by the filter; a correcting circuit to correct an output of the filter in accordance with the discriminated structure; and a binarization unit to binarize the output of the filter. By executing the reduction suitable for the image content in consideration of the peripheral images of the object pixel to be reduced and the peripheral reduced images, a reduced image can be obtained without extinguishing the content of the image of the original size, and especially, without fading or losing the thin lines in the reduced image.

    摘要: A wholly aromatic copolyester composed mainly of isophthalic acid units and hydroquinone units, the total proportion of said isophthalic acid units and hydroquinone units being at least about 80 mole % based on the entire units, said wholly aromatic copolyester having a terminal carboxyl group concentration, measured by the method described in the specification, of not more than about 90 eq/10.sup.6 g and a reduced viscosity, determined at 35.degree. C. in a mixed solvent of phenol and tetrachloroethane in a weight ratio of 4:6 in a concentration of 1.2 g/dl of at least about 0.6 and being substantially linear and melt-shapable and substantially free from a halogen atom bonded to the molecular chain, and a film prepared therefrom by melt shaping.
