Ritsuko Fuyuki 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).

  • Patent number: 7551206
    Abstract: An image-capturing apparatus according to the present invention can perform color reproduction processing appropriate to illuminants illuminating the subject, without an increase in memory capacity. For that purpose, the image-capturing apparatus of the present invention includes: an image-capturing unit generating a captured image of a subject; a recording unit recording one or more color reproduction matrices in association with each of a plurality of predetermined kinds of illuminants; a computing unit computing a corrected color reproduction matrix by performing interpolation processing based on at least two color reproduction matrices associated with different kinds of illuminants, out of the color reproduction matrices recorded in the recording unit; and a color reproduction processing unit applying color reproduction processing to the image generated by the image-capturing unit, by using the corrected color reproduction matrix.

  • Publication number: 20040085459
    Abstract: An image processing apparatus of the invention comprises an image processing part and a control part. The image processing part performs an image processing on an image signal. The control part obtains an influential factor of the image signal to control level of the image processing in accordance with the influential factor, the influential factor affecting a result of the image processing. The control part preferably evaluates reliability of the influential factor to adjust a level range of the image processing in accordance with the evaluated reliability. Such operation makes it possible to achieve a more effective image processing by widening level range upon obtaining a very reliable influential factor. Also, upon obtaining a not reliable influential factor, the level range is narrowed so that the image processing can be prevented from excessively varying.
