    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 printed-circuit board inspection apparatus for checking the condition of each circuit component mounted by soldering on a printed-circuit board is disclosed in which a luminance signal obtained from the reflected light scattering from the printed-circuit board being illuminated is converted through a given threshold level to binary signals, then the binary signals and mask data are processed to calculate the ratio of an area represented by the number of binary "1" signals to an area represented by the number of binary "0" signals, and the soldering condition of the component is judged based on the area ratio. With this arrangement, the inspection is not negatively influenced by the misalignment of the component with a mating soldering land, is capable of judging the amount of solder, and can be performed automatically and efficiently. The binary signals may be converted into code data by assigning a code "1" or "0" to each of a plurality of split masks set on each soldering land, depending on the largeness of the area in which the number of binary "1" signals "1" is larger than the number of binary "0" signals or vice versa. In this case, the judgment of the soldering condition is made by comparing the code data with code patterns contained in a predetermined code table.
