摘要： Even if the ratio between blue and green components of illumination light is changed, a plurality of types of blood vessels at different depths are reliably distinguished. A blue signal B, a green signal G, a red signal R is obtained by imaging the subject using a color CCD 44. A B/G image having a B/G ratio is generated. A superficial blood vessel extraction image is obtained by extracting a pixel, in which the B/G ratio is equal to or less than a boundary value Ls between the mucous membrane and the superficial blood vessel, from the B/G image. A medium-deep blood vessel extraction image is obtained by extracting a pixel, in which the B/G ratio is equal to or greater than a boundary value Ld between the mucous membrane and the medium-deep blood vessel. The boundary values Ls and Ld differ depending on the light amount ratio.

摘要： An electronic endoscope has normal and high-sensitivity image sensors. In a special mode for imaging an oxygen saturation level of blood, one of the normal and high-sensitivity image sensors is selected in accordance with a reflected light amount of special illumination light. When the normal image sensor is selected, the normal image sensor captures an image under irradiation with the special illumination light and outputs a second normal-sensor image. When an average pixel value of the second normal-sensor image is less than a first sensor selection threshold value, the use of the high-sensitivity image sensor is started. When the high-sensitivity image sensor is selected, the high-sensitivity image sensor captures an image under irradiation with the special illumination light and outputs a high-sensitivity-sensor image. When the average pixel value of the high-sensitivity-sensor image is more than a second sensor selection threshold value, the use of the high-sensitivity image sensor is stopped.

摘要： Illumination light for highlighting vessels and measurement light for measuring oxygen saturation level is applied alternately to a subject. A color image sensor images the subject illuminated with the illumination light and acquires a first blue signal, a first green signal, and a first red signal. The color image sensor images the subject illuminated with the measurement light and acquires a second blue signal, a second green signal, and a second red signal. An oxygen saturation level of hemoglobin in blood is calculated using the second blue signal, the first green signal and the first red signal. The first blue signal changed in accordance with the oxygen saturation level, the first green signal, and the first red signal are assigned to respective B, G, and R channels of a display. The display displays a “high-contrast vessel image with oxygen saturation level” that varies with the oxygen saturation level.

摘要： A distribution control unit of a CPU of an event reservation server distributes event information to a user terminal to present an event to a user. A request reception unit receives a participation application request from the user terminal to receive a participation application for the event by the user. A request reception unit receives the participation application request related to the participation application by the user for an event different from the application event before a start of the application event, as related information related to an application event that is the event in which the user applies for participation. In this case, an information acquisition unit acquires route information between a place of the application event and a place of the different event as first additional information. The distribution control unit distributes the route information to the user terminal to present the route information to the user.

摘要： There are provided a lesion part volume measuring method and an endoscopic diagnostic apparatus capable of easily detecting the volume of a lesion part without using a special treatment instrument. This problem is solved by detecting the position of a distal end portion of a scope hood from an image captured by an endoscope to which the scope hood is attached, finding the volume of the internal space of the scope hood, which is formed by the scope hood and the distal end surface of an insertion part, from the position of the distal end portion of the scope hood and the model of the endoscope and/or the model of the scope hood, and injecting water into the scope hood and detecting the volume of a lesion part from the difference between the water injection amount and the volume of the internal space of the scope hood.

摘要： There are provided an endoscopic diagnosis apparatus, lesion portion size detection method, and a non-transitory computer-readable recording medium that enable easy detection of the size of a lesion portion using an endoscope. This object is achieved by capturing an endoscopic image by emitting light having a regular repetitive pattern onto a subject, detecting, from the endoscopic image, a region in which a repetitive pattern is different from the repetitive pattern of the emitted light, and detecting at least one of a length and area of a lesion portion by using a number of repetitive patterns in the region in which the repetitive pattern is different and a size of a unit of repetition in the repetitive pattern.

摘要： There is provided a processor device for an endoscope capable of acquiring a blood vessel index value of a specific observation distance used for predetermined diagnostic criteria. A distance acquisition unit acquires a non-magnified observation distance at the start of the change of the imaging magnification, and acquires magnified observation distance at the end of the change of the imaging magnification. A distance ratio calculation unit calculates a first distance ratio between the non-magnified observation distance and the magnified observation distance. A blood vessel index value calculation unit calculates a blood vessel index value of the non-magnified observation distance from the image signal acquired at the non-magnified observation distance. An index value correction unit corrects the blood vessel index value of the non-magnified observation distance according to the first distance ratio to acquire a blood vessel index value of the magnified observation distance.

摘要： An endoscope image input unit 60 receives a current endoscope image signal that is output from an endoscope, which is currently inserted into a subject, and is used to calculate the oxygen saturation. A spectral estimation section 70 generates a spectral estimation image by performing spectral estimation processing on a past endoscope image signal that is obtained during the past endoscope insertion and is different from a signal for oxygen saturation calculation. An oxygen saturation calculation section 74 calculates the current oxygen saturation based on the current endoscope image signal, and calculates the past oxygen saturation based on the spectral estimation image. An oxygen saturation image generation section 80 generates a current oxygen saturation image based on the current oxygen saturation, and generates a past oxygen saturation image based on the past oxygen saturation. A monitor 18 displays the current oxygen saturation image and the past oxygen saturation image.
