Abstract:
An information processing apparatus for predicting a success or failure of differentiation of cells on the basis of a captured image obtained by imaging a cell population cultured in a cell-culture container includes at least one processor. The at least one processor extracts a feature quantity based on an appearance of the cells by performing image processing on the captured image, and predicts the success or failure of differentiation of the cells on the basis of the extracted feature quantity.

An observation apparatus includes an acquisition unit that acquires positional information indicating a position of a bottom surface of a support for supporting an observation target, an imaging optical system that forms an optical image showing the observation target supported by the support on an image plane, a focus adjustment unit that adjusts a focal position of the imaging optical system based on the positional information acquired by the acquisition unit, and a control unit that performs control for matching an inclination of the image plane on which the optical image is formed to an inclination of an imaging surface of an imaging element based on the positional information acquired by the acquisition unit.
Abstract:
Before an observation region of the imaging optical system reaches an observation position in a culture container, a vertical position of the culture container at the observation position is precedently detected by an auto-focus displacement sensor. In a case where an auto-focus control is performed on the basis of the position, an error between the precedently detected vertical position of the container at the observation position and a vertical position of the container at a time point when an observation region of the imaging optical system is scanned up to the observation position is acquired, and an objective lens is moved in an optical axis direction on the basis of the error.
Abstract:
Information for assisting a doctor based on the oxygen saturation of an observation target is presented. An endoscope system includes a light source device, an image sensor, an oxygen saturation calculation unit, a distribution pattern generation unit, a disease state score calculation unit, and a monitor. The light source device emits light to irradiate the observation target. The image sensor images the observation target with reflected light of the light, and outputs an image signal. The oxygen saturation calculation unit calculates an oxygen saturation of the observation target based on the image signal. The distribution pattern generation unit generates a distribution pattern showing the distribution of the oxygen saturation. The disease state score calculation unit calculates a disease state score indicating the disease state of the observation target based on the distribution pattern. The monitor displays the disease state score or information based on the disease state score.

Abstract:
An information processing apparatus includes an acquisition unit that acquires an output image output from a trained model as a result of causing the trained model to perform semantic segmentation in which discrimination of a class which is a type of an object appearing in an input image is performed on a pixel-by-pixel basis, an evaluation unit that evaluates validity of the semantic segmentation based on the output image, and a display controller that performs control such that an evaluation result indicating that the semantic segmentation does not have validity is displayed in a case where the evaluation unit evaluates that the semantic segmentation does not have validity.
Abstract:
A detection section detects a position of a container in a vertical direction, and an imaging optical system controller acquires an adjustment value of an imaging position of an imaging optical system according to the detected position. A correction section corrects the adjustment value according to a change in a refractive index of the container according to a temperature of the container. The imaging optical system controller adjusts an imaging position of an observation target on the basis of the corrected adjustment value.
