摘要:
An image processing apparatus, method and computer program that controls so that an image of image data is displayed on a display unit, controls so that a region of interest is indicated on the displayed image to acquire image data of the region of interest, generates an extraction region extracted from the image data by using each of the image segmentation algorithms to acquire the image data of the extraction region, calculates similarity by comparing the image data of the extraction region with the image data of the region of interest to select the image segmentation algorithm having highest similarity, and outputs image data extracted using the selected image segmentation algorithm to the display unit.
摘要:
In order to make observation of localizations of in vivo expressed genes possible in an entire individual living organism such as animals, and plants, a living genetic recombinant specimen containing a marker that can be detected at the time when specific genes are expressed is sequentially severed, sectional images each of which corresponds to an image of sections severed are photographed in every scissions of the living specimen, and three-dimensional observation of the living specimen is implemented on the basis of the images photographed in every scissions described above, whereby three-dimensional localizations of expressed genes are observed in the living specimen.
摘要:
A metal part is uniformly cooled by uniformly breaking a vapor film formed when a cooling liquid vaporizes on a surface of the metal part. Oscillations are applied to the vapor film formed on the surface of the metal part, whereby the vapor film is broken without the stirring of a cooling liquid 1. The cooling liquid 1 is stirred after the vapor film begins to be broken, whereby bubbles formed by the breakage of the vapor film are caused to diffuse in the cooling liquid 1.
摘要:
A finder has a display for displaying an image, and a finder optical system for observing the image therethrough. The spacing between the display and the whole of the finder optical system is relatively varied to thereby effect the adjustment of the field of view.
摘要:
For a single lens reflex camera in which an image bearing beam from the photographic objective is reflected by a movable mirror to the finder system, techniques are disclosed that the mirror is made half-reflective, and the transmitted light of the mirror is conducted by a supplementary optical member consisting of, at least, a prism fixedly secured (not movable relative) to the mirror toward an image sensor such as that of a focus detector positioned outside the optical axes of the objective and finder, that the movable mirror is made to take a quite different direction of movement from that to which the reflected beam from the mirror goes, and that as an image pickup device such as CCD is arranged on the optical axis of the objective and behind the movable mirror, the optical characteristics of optical members such as a filter positioned in front of the image pickup device are made equivalent to those of the supplementary optical member.
摘要:
The disclosed apparatus includes a finder optical system with a liquid crystal display having a plurality of strips of transparent conductive material arranged to display a frame for photography and a light metering area in the field of view of the finder. The liquid crystal display is energized in selected or all areas depending upon which position the objective lens takes when focusing and when zooming, or upon the set value of focal length in an objective lens of zoom type, and upon the in-focus signal of an auto-focus camera. The parallax between the photographic framing of viewfield and the rangefinder view is corrected and the rangefinder spot is displayed in a corrected position.
