    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.
