  • Patent number: 8044974
    Abstract: An image creating apparatus capable of creating cell images allowing reliable determination of cell structures in a cell is provided. This image creating apparatus comprises an image pickup portion picking up a plurality of images of a cell on different focal positions and an image synthesizing portion classifying the plurality of images picked up by the image pickup portion into a plurality of depth ranges as to the focal direction and synthesizing the plurality of images belonging to the respective ones of the plurality of depth ranges every plurality of depth ranges thereby creating focus-synthesized images in focus over corresponding depth ranges every plurality of depth ranges.

  • Publication number: 20080199066
    Abstract: The present invention is to present a sample image obtaining method that is capable of reflecting the blood cell concentration of a sample and increasing the speed of the examination. The sample image obtaining method comprises steps of: (a) obtaining a wide area image of a sample by imaging, at a predetermined magnification, a wide area including a smearing end of a smear region on a slide glass where the sample is smeared; (b) detecting the smearing end based on luminance information of the wide area image of the sample; (c) determining an imaging region in the smear region based on the detected smearing end; and (d) obtaining a sample image by imaging the determined imaging region at a higher magnification than the predetermined magnification.

  • Publication number: 20060109343
    Abstract: An image displaying system is described that includes (a) an image providing apparatus comprising a first transmitting means for transmitting a first image of a cell, and a second transmitting means for transmitting a second image of a higher resolution than the first image of the cell shown in the first image; and (b) an image displaying apparatus comprising an image display unit, a first receiving means for receiving the first image transmitted from the image providing apparatus, a second receiving means for receiving the second image transmitted from the image providing apparatus, a first display means for displaying the first image in a first region of the image display unit, and a second display means for displaying the second image in a second region of the image display unit, wherein the second transmitting means transmits partial images required for display by the second display means on a priority basis relative to the other partial images among a plurality of partial images of the segmented second i
