  • Publication number: 20200166533
    Abstract: A smear transporting apparatus transports a smear slide on which a sample is smeared to a smear-image capture apparatus. The smear transporting apparatus includes a smear-container transport part that transports a first smear container accommodating smear slides to a smear pickup position; a smear transfer part that picks a smear slide whose image is to be captured by the smear-image capture apparatus from the first smear container transported to the smear pickup position, transfers the smear slide to the smear-image capture apparatus, and places the smear slide whose image has been captured by the smear-image capture apparatus in a second smear container different from the first smear container; and a storage that stores the first smear container and the second smear container.

  • Patent number: 7643143
    Abstract: A particle image analyzing apparatus for analyzing an image of an imaged particle, the particle image analyzing apparatus comprising: an illuminating unit for providing dark field illumination the a particle; an imaging unit for acquiring capturing an imaged image by imaging the dark field illuminated particle; and an image processing unit for extracting a particle image from the imaged image captured by the imaging unit, based on a threshold value larger than a luminance value substantially corresponding to the background of the particle image, and analyzing the extracted particle image to obtain morphological feature information indicating the morphological feature of the particle; wherein the image processing unit extracts the particle image from the imaged image based on a threshold value larger than a luminance value substantially corresponding to the background of the particle image.
