摘要： The invention relates to a method for processing an image signal such that areas of original image data are sequentially scanned with a scanning window having a size corresponding to M picture elements in units of a predetermined number of picture elements so as to perform halftone display in accordance with black-and-white binary distribution with respect to the signal levels of the picture elements within the scanning window every time the scanning window is moved. The picture elements within the scanning window are assigned an order of preference in accordance with their image signal levels. A sum of the image signal levels of the picture elements within the scanning window is calculated, and A and N of the equation S=C.times.N+A are calculated, where C is a predetermined image signal level (e.g., black level and maximum level), N is an integer, and A is the image signal level falling within the range 0.ltoreq.A

摘要： In a variable density scanner a light beam of a fixed spot size is scanned on an original along each of a plurality of parallel line paths at a constant speed to generate a video signal and successively shifted to the next line path. The video signal is sampled to generate a video sample. Each of the line paths is divided into a plurality of line segments so that each segment derives a plurality of video samples and the line paths are formed into a plurality of groups of adjacent line paths so that the video samples are derived from a plurality of patterns of rows and columns. The total value of the video samples of each pattern is arithmetically divided by their number in response to the control signal to derive an average value.

摘要： An image processor for reproducing a continuous tone image such as a photograph in a black-and-white binary dot image (halftone image) has a linear correction section for converting a sampled digital image signal in a predetermined manner controlled by black and white densities of an original, thereby performing linear conversion between the continuous tone image and the halftone image. The image processor also has another correction section for performing profile emphasis to obtain a clear halftone 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： 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.

摘要： A system for inspecting a condition of parts packaged on a printed-circuit board. The inspection system includes a position detecting device to receive scattered light due to illumination of the printed-circuit board with a laser beam and convert the received scattered light into a position signal. This position signal is used for obtaining luminance data and at least two height data of the parts on the printed-circuit board. Proper height data of the parts is determined on the basis of the difference between the two height data. The inspection system determines the package condition by comparing the final height data with a predetermined reference data.
