  • Patent number: 9829690
    Abstract: To provide a microscopic imaging device in which a measuring object can be easily imaged using measurement light having a desired pattern, in which the pattern of measurement light can be changed and a phase of the pattern can be moved, without arranging a mechanical mechanism. An arbitrary pattern of a plurality of patterns of measurement light is instructed. The measurement light having an instructed pattern is generated by a light modulation element, and is applied on a measuring object. A spatial phase of the generated pattern is sequentially moved on the measuring object by a predetermined amount by the light modulation element. A plurality of pieces of pattern image data generated at a plurality of phases of the pattern is synthesized based on the light receiving signal output from the light receiving section to generate sectioning image data indicating an image of the measuring object.

  • Patent number: 9122048
    Abstract: Provided is an image processing apparatus and an image processing program which are capable of selectively and readily acquiring a geometrical physical quantity of a desired measuring portion. An object image is displayed based on object image data, and a measuring portion designating image corresponding to a specific portion of the object image is displayed based on designating image data. By operation of an operation part by a user, the displayed measuring portion designating image is moved relatively to the object image. When the measuring portion designating image is moved to a specific portion of the object image, a geometrical physical quantity of a measuring portion of the measuring object, previously set so as to correspond to that specific portion, is measured.

  • Publication number: 20150116477
    Abstract: To provide a microscopic imaging device, a microscopic imaging method, and a microscopic imaging program capable of detecting a focused position through an appropriate method corresponding to the imaging method. In a sectioning observation, a measuring object is irradiated with pattern measurement light, and sectioning image data is generated. In a normal observation, the measuring object is irradiated with uniform measurement light to generate normal image data. Relative positions of an objective lens and the stage are changed a plurality of times in an optical axis direction of the objective lens by a focus position adjustment mechanism. When the sectioning observation is instructed, a focused position is detected based on the value of each piece of pixel data of the sectioning image data. When the normal observation is instructed, a focused position is detected based on a local contrast of the normal image data.

  • Patent number: 8994810
    Abstract: Provided is a magnification observation device capable of easily moving an observation object in a desired direction even when a stage is rotated, and capable of preventing a desired region of the observation object from going outside an imaging region due to rotation of the stage. The observation object is placed on the placement surface of the stage. The observation object is imaged by an imaging unit, to acquire image data of the imaging region. Based on the image data acquired by the imaging unit, an image of the observation object is displayed by the display part as an observed image. The stage is moved relatively with respect to the imaging unit along an xt-axis and a yt-axis. In this case, moving amounts along the xt-axis and the yt-axis are controlled based on a rotational angle detected by a rotational angle detecting part.

  • Patent number: 8656144
    Abstract: The invention provides an image processing device, an image processing method, and an image processing program which enable accurately observing a moving image of an object within a time interval within which the object is in a desired state. A control unit performs an analysis process after the elapse of every defined time period. As the analysis process, the control unit acquires evaluation values corresponding to image data of a plurality of frames stored within a latest defined time period and, based on the acquired evaluation values, selects a group of reproduction data formed from image data of a certain number of frames, out of the image data of the plurality of frames stored within the latest defined time period. After the completion of the analysis process, the control unit starts reproduction of a moving image based on the group of reproduction data selected through the analysis process.
