摘要： An oblique projection original is formed by deforming an orthogonal projection original in such a manner that a rectangular original is transformed into a trapezoidal original by compressing the orthogonal projection original by thinning scanning lines in a horizontal direction. In addition, predetermined bits in each scanning line are thinned in a vertical direction, and each line is compressed by reducing first and last portions of each line by half the number of bits thus thinned. Finally, white bits are inserted at the first and last portions of each scanning line to complete each scanning line.

摘要： An image transcribing system for transferring an image from an original document to a recording sheet in which the original image is scanned, converted to binary signals and stored in a first page memory. An image processing section transfers the image data from the first page memory to a second page memory while it is simultaneously enlarged by a predetermined factor. In the enlargement process, the image data is first enlarged by an integer factor then reduced by a fractional factor in accordance with stored bit patterns corresponding to the required fractional factor.

摘要： An input and/or output unit which reads or records a picture utilizing a scanning beam in which sampling positions of picture elements in a main scanning direction are uniformly spaced. A first clock signal is produced which is at least three times as high in frequency as an output sampling clock signal. The first clock signal operates a counter, the output of which is compared with the output of a ROM. The ROM is addressed by a counter which is incremented by output comparison pulses. The output of the comparator is also utilized as the output sampling signal. Numerical values are stored in the ROM such that the output pulses from the comparator occur at times corresponding to constant sampling intervals of the scanning beam along a scanning line.

摘要： Apparatus for producing and reproducing embedded patterns in which a character or the like including a pattern which is not observable macroscopically can be differentiated from the other formats microscopically. An input unit reads a normal original image pattern utilizing a raster scanning system. In the apparatus for producing the format, a processing unit includes a gate which receives a signal from the input means and passes or blocks the signal in accordance with the desired embedded pattern. An output unit records the image using the raster scanning system. In the apparatus for reproducing the format, a processing unit includes a gate which blocks or passes an input signal depending on whether or not it contains the embedded pattern.

摘要： An apparatus and method for reading, processing, storing and later printing out stored data from an original document in which undesired data portions are prevented from being recorded. Portions of the printed original image which are desirably retained and recorded are printed with solid lines, while image portions, for instance, ledger lines, which are desirably not retained and recorded, are printed as optically fine discontinuous patterns. The original thus printed is scanned line by line. The analog signal which is produced by the scanning device has high frequency portions when an optically fine discontinuous pattern is scanned. These portions are eliminated by low-pass filtering or by determining the degree of correlation between the sensor output signal and stored data representing the optically fine discontinuous patterns.

摘要： A multilevel image printing device in which a laser beam is scanned onto the surface of a photoconductive drum with plural intensity levels without the use of a modulator. A multilevel image outputting circuit produces a multilevel signal which is applied to a multilevel image signal to laser beam conversion circuit which converts it into an intensity value for operating a semiconductor laser beam source. The multilevel image signal to laser beam conversion circuit includes plural switches which are operated in response to the multilevel image signal coupled through resistors of different values which determine the voltage applied to the semiconductor laser beam source.
