Patent
Processing method for picture information
TL;DR: In this paper, a picture inputting from a scanner not being a surface part is subjected to emphasis processing by revising a threshold level or a picture element position at which density difference from a noted picture element is detected depending on linear density of picture information.
Patent
Non-contact type bearing structure
TL;DR: In this article, a non-contact type bearing structure is constructed by using a ring magnet with a larger diameter and a smaller diameter, and the ring magnet is made to repel each other by making mutually opposing magnetic poles to be the same pole.
Patent
Multi-valued image binarization method
TL;DR: In this article, a multi-valued image is converted into a binary image which is made high in density without using any page memory by converting a multiview data into binary image data having the read density increased by prescribed times in main scanning and sub scanning directions.
Patent
Method for deciding optimum line density of picture processor
TL;DR: In this paper, the authors proposed a line density deciding method to prevent the degradation of picture quality and to correctly set an optimum line density by counting the appearing number of times of the various kinds of the run lengths of binary picture information obtained by reading original pictures at a high line density.
Patent
Picture synthesis system
TL;DR: In this article, the same dither matrix is used to save the capacity of a picture memory and to reduce the cost of the picture synthesizer by applying binary processing to a picture data of two pictures.
