摘要： Light beams scans patterns of a subject copy, being reflected therefrom, and being converted into pulsating electrical signals. Color borders between two different colored patterns are detected based on the pulsating signals. On the other hand, a color of a predetermined scanned line following each of the color borders is sensed for determining the sensed color as a color between the adjacent color borders.

摘要： A color print painted with different colors C.sub.i (i = 1, 2 . . . n) is scanned by a color scanner along a plurality of successive line paths to generate a set of electrical signals each representing the intensity of the spectral components of the light reflected from an elemental area of the print. A macroscopic color separator is provided to generate a set of electrical signals each representing the average spectral intensities per unit area of the print. A data processor is used to compute the probability P(C.sub.i) from the data obtained from the macroscopic color separator and a set of mean spectral intensities exhibited by the color samples with which the print is painted by artisans. In accordance with the Bayes' Rule, the processor then executes computation of the product of P(C.sub.i) and the conditional probability of occurrence of elemental color spectral intensities given that the elemental area being scanned belongs to a particular color sample, using the data received from the color scanner as it scans the print.

摘要： A colored original which is painted with a plurality of predetermined colors is scanned along each of a plurality of line paths each of which can be divided into one or more colored line segments. Encoders are provided to characterize each of the line segments by a corresponding first code representing the color of the segment and a second code representing the run length of the segment. The first and second codes are sequentially recorded in a data file memory. The recorded information is repeatedly retrieved from the memory and transferred to a shift register. Line segments carrying the same color within each line path are detected by comparing the corresponding first code with a specified code. The second code is sequentially decoded into run lengths which are accumulated to measure the position of color transitions relative to the colored original. A video signal is generated upon occurrence of coincidence between the first code and the specified code. A photographic film is scanned by a light beam modulated with the video signal to develop an image carrying the detected color on a specified portion of the film in correspondence with the specified code. The codes to be specified are sequentially changed to detect the line segments of different colors in a predetermined sequence within the period of the scanning. In synchronism with the code change, the shift register is shifted to recirculate the data.

摘要： A two-valued object such as black-and-white textural or pictorial material is repeatedly scanned aong each of a plurality of line paths within the object to produce an image signal which is representative of a series of black and white runs or areas within the line path. The length of black or white run or "run length" is sampled by clock pulses and translated into a binary code and transmitted bit by bit at the line scan rate to a receiver station. A vertical sync pulse is inserted at the end of the (n-1)th run length wherein n represents the number of run lengths within the image signal so that the last run length is skipped. The last run length so skipped at the transmitter is reconstructed at the receiver during the time interval of the vertical sync pulse.

摘要： A correspondence relation between a structure of a bi-level pattern A and a structure of a bi-level pattern B is statistically learned by use of a learning high-density image. The bi-level pattern A forms a partial region of a low-density character and line image except a screened dot image. The bi-level pattern B forms a corresponding partial region of a desired high-density image. A judgement is made as to whether the low-density image is equal to or different from a screened dot image. Reference pixels are selected from the partial region of the low-density image. The low-density bi-level pattern A is converted into the high-density bi-level pattern B on the basis of a result of the learning by use of the selected reference pixels when the low-density image is different from a screened dot image. A pixel of the low-density image is repeated to convert the low-density image into the high-density image when the low-density image is equal to a screend dot image.

摘要： An apparatus for receiving input data values representing an array of picture elements of a source image containing one or more bar code regions, whereby the input data values are converted to bi-level values representing black or white states which are stored in an image memory, while in addition the bi-level values are processed to obtain data representing an image in which a "skeleton" central portion of the bar code region appears as an all-black region, while background black regions are eliminated. A central position and the slope of a central axis of the bar code region are computed based on that "skeleton" region, and data values in the image memory which conform to the central axis are then read out, to read the bar code data.

摘要： An image signal processing apparatus for converting input signal values representing density levels of successive picture elements of an image to corresponding bi-level signal values, whereby a conversion error for an object picture element is apportioned among a set of unprocessed adjacent picture elements, to update respective values of accumulated error. Each input signal value is compensated, prior to conversion, by a value derived from the total accumulated errors of the object picture element and these adjacent picture elements, while the conversion error is derived by subtracting from the bi-level output value a value obtained by compensating the input signal by the accumulated error for the object picture element.
