Kaneyasu Okawa 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: 7573506
    Abstract: An imaging apparatus evaluation method of the present invention comprises obtaining an output function of original image data by comparing a plurality of sets of image data which are obtained by imaging the same spatial brightness distribution surface with different exposure times.
    Type: Grant
    Filed: October 6, 2005
    Date of Patent: August 11, 2009
    Assignee: Olympus Corporation
    Inventor: Kaneyasu Okawa
  • Publication number: 20080181458
    Abstract: In a light intensity measurement method of acquiring an image of a subject for detection, in which a plurality of target areas to be detected, each having a predetermined area, are arranged, and of measuring light intensity of each target area by analyzing the acquired image, each area smaller than the predetermined area is extracted as a noise area, from among areas extracted from the acquired image based on light intensity thereof, and is removed from the image. A light intensity measurement system has a device for emitting light to the subject; a device for acquiring an image of the subject to which the light is emitted; a device for storing the acquired image; a device for extracting each area, which has an area smaller than the predetermined area, as a noise area from the stored image; and a device for removing the noise area from the stored image.

  • Patent number: 7224826
    Abstract: A fluorescent image is obtained by emitting the light with a wavelength which excites a labelling fluorescent substance, a mask is created by a foreign matter area image extracted from an image of foreign matter adhering to the measurement object obtained by emitting light with a wavelength which does not excite the fluorescent substance, and logical multiplication of the mask and the fluorescent image is executed, thereby obtaining a fluorescent image that a foreign matter area is eliminated from the fluorescent image.

  • Patent number: 7027932
    Abstract: According to the present invention, there is provided a biochemical examination method of supplying a solution of a first biochemical material into an array of which respective second biochemical materials are held, and using a marker by a luminescent molecule to detect a luminescent intensity of the luminescent molecule for each probe array element of the array with an array type detector, so that a reaction state of the first biochemical material with the second biochemical materials is examined for each probe array element, the method comprising: irradiating a reference array by which the luminescent molecule is held with an excitation lighting to photograph a reference light image; irradiating the array for biochemical examination with the same excitation lighting to photograph a sample light image; and correcting the sample light image with the reference light image.

  • Publication number: 20050153356
    Abstract: An image processing method for a biochemical test of the present invention shoots a light image as a sample image by applying excitation illumination to an array for the biochemical test, extracts, as a reference image, a background image obtained by excluding an image of a micro pattern indicating fluorescence light generated from each probe array element from the sample image, and corrects the sample image by use of the reference image.
