Takeshi Kowada 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 processing apparatus with ground-tint pattern recognition and abnormality detection
    Patent number: 7518742
    Abstract: An image processing apparatus includes a controlling unit that controls all units of the image forming apparatus, a reading unit that reads an image, a processing unit that generates image data based on the image read, a recognizing unit that recognizes a ground tint pattern in the image read, and a detecting unit that detects an abnormality in the recognizing unit. When the recognizing unit recognizes a ground tint pattern in an image read, the controlling unit controls the processing unit to perform a special processing on the image. When the detecting unit detects an abnormality in the recognizing unit, the controlling unit controls the image forming apparatus according to the abnormality.

  • Image forming device with ground-tint detection, image invalidation, and read resolution setting
    Patent number: 7502141
    Abstract: In an image forming device, a ground-tint detection unit detects a ground-tint pattern in an original image based on image data output from an image reader unit. An image invalidation unit outputs a processed image data that makes the image data of the original image illegible, when the ground-tint pattern in the original image is detected. A resolution setting unit allows a resolution of the image reader unit to be higher than a minimum resolution needed for detection of a ground-tint pattern and stored in a memory unit.

  • Image forming apparatus, image processing unit, and image forming method to keep image quality precision of both sides of recording medium, and computer product
    Patent number: 7062185
    Abstract: When a reading unit reads information of a pattern image for correcting image quality printed on at least either side of a recording medium, a control unit compares the information of the pattern image for correcting image-quality with correction pattern information that is a basis of the pattern image for correcting image quality transferred to the at least either side of the recording medium, and controls an image forming unit based on a result of the comparison to correct image quality on the at least either side of the recording medium.
