| Number | Title | Issue Date |
| 4809082 | Method of and apparatus for generating image data used to record an image having gradation Gradation levels of an image to be recorded are expressed by gradation data having integral parts and decimal parts. Random numbers are composed with the decimal parts to provide composite values. When the composite value exceeds, the quantity is added to... | 02/28/1989 |
| 4742400 | Digital image processing device for intermediate tone A digital image processing device for intermediate tone having threshold value tables provided with threshold values different from each other set for each of picture elements in a unit region containing a plurality of picture elements for gradation proce... | 05/03/1988 |
| 4700235 | Method and apparatus for producing half-tone printing forms with rotated screens on the basis of randomly selected screen threshold values In a method and apparatus for producing half-tone printing forms with screens having arbitrary screen angles and screen width, screen dots are exposed on a recording medium by means of a recording element whose exposure beam is switched on and off by a co... | 10/13/1987 |
| 4622595 | Image display unit capable of tone reproduction An image reproducing apparatus wherein a halftone of an image is reproduced by repeating a picture element pattern composed of a plurality of dots as a unit and each dot display density of which is gradually controlled. The repetition of the same picture ... | 11/11/1986 |
| 4482923 | Method for autotypical tonal value analysis Method for producing a printing form by means of scanning a master and the recording surfaces in accord with a scanning raster or, respectively, a conforming recording raster upon employment of a random generator for the distribution of smallest points wh... | 11/13/1984 |
| 4450485 | Image scanning and recording method An image scanning and recording method wherein a random pulse signal is added either to the image signal obtained by scanning a continuous tone original or to the dot signal controlled synchronously with the scanning of the original. The image signal and ... | 05/22/1984 |
| 4340912 | Random screen generator apparatus for producing halftone images An apparatus is provided for generating a random (mezzotint) screen for producing halftone copies of continuous tone documents. The random screen comprises a matrix of random numbers representing a sequence of digital reference values with respect to whic... | 07/20/1982 |
| 4033443 | Logic circuit for grey-tone printer Method and apparatus for producing a grey-tone image having areas of different average density values which are given by an n-digit binary number, all the bits of the binary number being interrogated in parallel by clock patterns. For the area to be print... | 07/05/1977 |
