摘要： An endoscopic image processing apparatus is configured to create a three-dimensional shape model of an object by performing processing on an endoscopic image group of an inside of the object, and includes a processor. The processor estimates a self-position of the image pickup device based on the endoscopic image group, calculates a first displacement amount corresponding to a displacement amount of the image pickup device based on an estimation result of the self-position of the image pickup device obtained by the estimation, calculates a second displacement amount corresponding to a displacement amount in a direction parallel to a longitudinal axis direction of the insertion portion, based on a detection signal outputted from an insertion/removal state detection device that detects an insertion/removal state of an insertion portion inserted into the object, and generates scale information in which the first displacement amount and the second displacement amount are associated with each other.

摘要： In a three-dimensional image display method, a processor acquires first three-dimensional data and second three-dimensional data of a subject from a recording medium. The processor converts a first three-dimensional coordinate system of the first three-dimensional data and a second three-dimensional coordinate system of the second three-dimensional data into a three-dimensional common coordinate system on the basis of structure information related to a geometric structure of the subject. The processor displays an image of the first three-dimensional data in the common coordinate system and an image of the second three-dimensional data in the common coordinate system on a display.

摘要： A cell analyzing device includes a control circuit. The control circuit acquires data of an observation image. The control circuit specifies a colony of a cultured cell in the observation image. The control circuit calculates a ratio at which the cultured cell occupies a predetermined range included in the observation image as an occupancy rate. The control circuit calculates a size of the colony. The control circuit determines a state of the cultured cell based on the occupancy rate and the size of the colony.

摘要： An insertion state determination system includes a sensor unit including a first sensor and the system includes a second sensor and a processor. The first sensor is configured to determine a first rotation amount indicating a rotation amount of an elongated insertion unit of an endoscope device around a center axis of the insertion unit. A hole through which the insertion unit passes is formed in the sensor unit. The second sensor is disposed in the sensor unit or an object fixed to the sensor unit and is configured to determine a second rotation amount indicating a rotation amount of the sensor unit around the center axis when the insertion unit is inserted into the subject. The processor is configured to calculate a corrected rotation amount by correcting the first rotation amount based on the second rotation amount.
