Abstract: A CPU of an information processing server includes an acquisition unit, a derivation unit, and a distribution control unit. The acquisition unit acquires an image captured by a user during a target event for which a satisfaction level of the user is measured. The derivation unit derives the satisfaction level of the user with the target event based on the image. The distribution control unit presents an attribute of the user and satisfaction level-related information which is related to the satisfaction level to an organizer of the target event.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: In a special mode for imaging an oxygen saturation level of blood, an internal body portion is imaged under irradiation with special illumination light. A light amount evaluation section judges based on an obtained image whether or not a reflected light amount of the special illumination light is adequate for calculating the oxygen saturation level. When the reflected light amount is judged to be adequate, a normal image sensor captures an image under irradiation with the special illumination light. When the reflected light amount is judged to be low, a high-sensitivity image sensor is used. In using the high-sensitivity image sensor, a binning process is applied to an image signal in accordance with the reflected light amount of the special illumination light, in order to further sensitize the image signal.

Abstract: 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.

Abstract: 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.

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.

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 each observation mode.

Abstract: In an electronic endoscope system, a changed-area detector detects a changed area from an image captured by an endoscope, the changed area having different features from other area of the captured image. A mask data produce produces mask data based on the detected changed area, the mask data allocating an image processing parameter to each pixel of the captured image such that the changed area is processed in a different way from the other area. An image processor processes the captured image according to the mask data. Thus, an image area corresponding to an artificial object like a surgical tool may be detected as the changed area and excluded from unnecessary image processing.
