摘要： An image signal processing circuit for converting a continuous tone image signal to a bi-level image signal, for producing a spatial gray scale image on a bi-level display device such as a gas plasma display panel. Respective values of apportionment factors (K.sub.A to K.sub.D) used for apportioning a bi-level conversion error of each picture element of the image among a plurality of picuture elements (A to D) positioned peripehrally adjacent thereto are periodically altered, in a periodic or random succession of values, to thereby effectively eliminate the generation of a texture pattern in display regions corresponding to areas of uniform density in the original image.

摘要： An image signal processing circuit for converting step-gradation density values (I.sub.xy) of successive picture elements to bi-level values (P.sub.xy) for display by a bi-level display device, in which a bi-level error (E.sub.xy) between a bi-level value determined for a picture element and an appropriate density value for the element is apportioned among a set of peripherally adjacent picture elements (A to D) by computing a corresponding set of error apportionment values (G.sub.A to G.sub.D), and in which a difference between the sum total of these apportionment values and the bi-level error is derived, and error apportionment is modified such as to eliminate the effects of this difference. Improved reproduction is thereby attained of image regions which are of uniformly high density or low density.

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.

摘要： An inspection apparatus for inspecting a wiring pattern on a printed board by illuminating the printed board with light to photoelectrically convert light reflected from the printed board into an optical grey level image corresponding to the wiring pattern thereon, the grey level image being converted into a bi-level image. The inspection apparatus includes a thinning circuit to perform a thinning process for removing the bi-level image by one picture element from the background side of the wiring pattern, the thinning process being repeatedly performed predetermined times with respect to all of picture elements of the wiring pattern to output the number of repetitions of the thinning process and further to output a skeleton image. Also included is a distance image converter to output a distance conversion image where the number of repetitions is given as a distance value from the background of the wiring pattern. The inspection apparatus compares the distance value of the distance conversion image with one or more thresholds along the skeleton image. This arrangement allows direct detection of the wiring pattern width, thereby permitting the wiring pattern inspection with a simple structure.

摘要： A method and apparatus for assembling a tire with a disc wheel under the optimum condition, in which inner diameter variation of the disc wheel, radial force variation of the tire proper, radial force variation of a wheel assembly body and existing assembled condition are displayed on separate channels of a display device, respectively. The radial force variation of the tire proper thus displayed is phase shifted by an angle at which the radial force variation of the wheel assembly body becomes minimum. The tire is then displaced with respect to the disc wheel by the above angle so as to obtain the optimum assembled condition.

摘要： The combination of: a) first and second spaced pulleys; b) an endless belt; and c) a belt installation jig having a body with: a pulley pressing part; a belt holding part; and a belt pressing part. The belt installation jig and belt cooperate so that with the belt operatively wrapped against the second pulley and partially operatively wrapped against the first pulley, turning of the first pulley causes the belt to progressively wrap around the first pulley to a fully operatively wrapped state, whereupon further turning of the first pulley situates the belt installation jig for separation from the belt and pulleys.

摘要： A wiring pattern inspection apparatus for inspecting an abnormality of a wiring pattern formed on a printed circuit board, which is equipped with an optical image pickup device for optically illuminating a surface of the printed circuit board including the wiring pattern to photoelectrically convert optical information of the printed circuit board surface due to the optical illumination into a grey level image. This grey level image is converted into a bi-level image which separates the grey level image into the wiring pattern side and a background side of the wiring pattern. Thereafter, the bi-level image is once contracted by a first size and then expanded by a second size so as to eliminate a micro conductive portion left on the printed circuit board or a micro pinhole which can be disregarded in the abnormality inspection, thereby preventing the excessive detection.

摘要： A beam of light is applied to a surface of a circuit board provided with at least one solder portion. The light beam scans the surface of the circuit board. Height data are derived from a portion of the light beam which is scattered at the surface of the circuit board. The height data represent a height of a currently-scanned point of the surface of the circuit board. The height data are accumulatively added for the solder portion. A variation in the height data is calculated. The accumulative addition of the height data is executed and suspended in response to the calculated variation in the height data. A decision is made as to whether the solder portion is acceptable or unacceptable on the basis of a result of the accumulative addition.
