摘要:
An apparatus for processing character or pictorial image or the like for splitting the outline of a character, which is developed on x- and y-coordinates, into a plurality of blocks [P.sub.1, P.sub.n ] (where P.sub.1 and P.sub.n are a start point and an end point of an arbitrary block respectively) each defined by a univalent function involving x as a variable, then producing block data to specify the shape of each block, and storing a set of such block data as the compressed data of one character to accomplish compression of the data.
摘要:
A character image data compression system for compressing binary data from an image corresponding to a two-dimensional character image, making it possible to optionally output the coded data in conformity with the characteristic of a character image having complicated composition, thereby to improve the data compression ratio as a whole character and make the capacity of a character data memory compact.
摘要:
A method for compressing character or pictorial image data which contemplates to compress a quantity of data by means of a method for establishing sampling points and a method for establishing blocks as well as storing information for specifying outlines of a character in the case where the outlines of character, pictorial image or the like are approximated with sets of functional curves or straight lines to effect data compression.
摘要:
Method and apparatus for storing and photo-typesetting characters and figures stored in the form of data of contours wherein unlike the conventional art, curves of contours are not approximated by straight lines, but are approximated by curves, that is, the data is stored to obtain a curve which is approximated to the curve of contour approximated to contours such as of characters and figures being reproduced based upon the stored data.
