Akira Ohori has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Image forming apparatus for printing additional data such as image forming condition data along with the image
    Patent number: 5677770
    Abstract: An image forming apparatus has an operating panel to input various image-forming conditions, an image processing member for processing an input image signal, an outputting member for outputting an image, and a controller. The controller controls the operating panel, the image processing member and the outputting member so as to print the image forming conditions themselves as part of an image on a piece of paper.

  • Graphic output device including antialiasing capability governed by decisions regarding slope of edge data
    Patent number: 5325474
    Abstract: A graphic output device for removing the aliases of the edges of a vector image by an antialiasing procedure and effectively outputting image data undergone such processing. Whether or not the inclination of an input vector is greater than 45 degrees is determined. In the event of outputting the result of antialiasing processing, a pulse width modulation system (vertically long dot diameter) is selected if the inclination of the vector is greater than 45 degrees, or a power modulation system (horizontally long dot diameter) is selected if it is smaller than 45 degrees.
