  • Patent number: 7796797
    Abstract: A apparatus for obtaining an image of a blood cell is described, a representative one of which includes image obtainer for obtaining an image of a predetermined blood cell in a blood sample smeared on a sample holder; an analysis result obtainer for obtaining an analysis result of the blood sample; and a controller for controlling the image obtainer such that the image obtainer obtains the image under a first imaging condition when the analysis result does not indicate a presence of a predetermined anomalous cell, and obtains the image under a second imaging condition to be different from the first imaging condition when the analysis result indicates the presence of the predetermined anomalous cell.

  • Patent number: 7589892
    Abstract: A specimen imaging apparatus is provided that is capable of improved high-speed operation compared to conventional apparatuses. The specimen imaging apparatus is provided with a microscope for enlarging the image of a specimen, and taking the enlarged image of the specimen obtained by the microscope. The apparatus is provided with a vibration detector for detecting a relative vibration between the objective lens of the microscope and the specimen mounted in the microscope, a focuser for focusing before the vibration detected by the vibration detector has attenuated to less than a predetermined value, and a controller for determining whether or not a vibration detected by the vibration detector is less than a predetermined value. The specimen imaging apparatus is configured so as to take the enlarged image of a specimen when the controller has determined that the vibration is less than a predetermined value.
