摘要： An apparatus is disclosed which includes a first and a second optical guides inserted in an elongated insertion portion thereof, and which can transmit an optical image, and an optical system with a function of imaging at the end surface of the optical guide. By transmitting an illuminating light from the other end surface to the portion to be observed through one of the optical guides, the portion to be observed is illuminated. While, the optical image transmitted through the other optical guide is introduced into an ocular system or an imaging system. By changing the functions performed by these optical guides, the stereoscopic observation and stereoscopic imaging can be realized.

摘要： A plurality of images inputted in an image signal input portion are divided into a plurality of regions by an image dividing portion, and a feature value in each of the plurality of regions is calculated by a feature value calculation portion and divided into a plurality of subsets by a subset generation portion. On the other hand, a cluster classifying portion classifies a plurality of clusters generated in a feature space into any one of a plurality of classes on the basis of the feature value and occurrence frequency of the feature value. And a classification criterion calculation portion calculates a criterion of classification for classifying images included in one subset on the basis of a distribution state of the feature value in the feature space of each of the images included in the one subset.

摘要： An endoscope device obtains tissue information of a desired depth near the tissue surface. A xenon lamp (11) in a light source (4) emits illumination light. A diaphragm (13) controls a quantity of the light that reaches a rotating filter. The rotating filter has an outer sector with a first filter set, and an inner sector with a second filter set. The first filter set outputs frame sequence light having overlapping spectral properties suitable for color reproduction, while the second filter set outputs narrow-band frame sequence light having discrete spectral properties enabling extraction of desired deep tissue information. A condenser lens (16) collects the frame sequence light coming through the rotating filter onto the incident face of a light guide (15). The diaphragm controls the amount of the light reaching the filter depending on which filter set is selected.

摘要： At step S1, a red image is acquired from among red, green, and blue images constituting a received endoscopic image. At step S2, M sampling-pixels (where M denotes an integer equal to or larger than 1) are selected from the data of the red image. At step S3, a gradient vector is calculated in order to determine the direction of a gradient in brightness represented by each sampling-pixel. At step S4, the direction of a lumen is detected. At step S5, the detected direction of a lumen is adopted as an inserting direction and arrow information is superposed on an image. The resultant image is displayed on a display device. Control is then returned to step S1, and the same steps are repeated relative to data of the next frame. Consequently, even if the lumen disappears from a field of view for imaging, the inserting direction can be detected.
