Abstract: A transfer learning apparatus includes a transfer target data evaluator and an output layer adjuster. The transfer target data evaluator inputs a plurality of labeled transfer target data items each assigned a label of a corresponding evaluation item from among one or more evaluation items to a neural network apparatus having been trained by using a plurality of labeled transfer source data items and including in an output layer output units, the number of which is larger than or equal to the number of evaluation items, and obtains evaluation values output from the respective output units. The output layer adjuster preferentially assigns, to each of the one or more evaluation items, an output unit from which the evaluation value having the smallest difference from the label of the evaluation item is obtained with a higher frequency, as an output unit that outputs the evaluation value of the evaluation item.

Abstract: A range-information acquiring apparatus includes a light source, an image sensor, a control circuit, and a signal processing circuit. The control circuit causes the light source to emit first light toward a scene and subsequently emit second light toward the scene, the first light having a first spatial distribution, the second light having a second spatial distribution. The control circuit causes at least a portion of plural photodetector elements of the photodetector device to detect first reflected light and second reflected light in the same exposure period, the first reflected light being caused by reflection of the first light from the scene, the second reflected light being caused by reflection of the second light from the scene. The signal processing circuit generates range data based on photodetection data output from the photodetector elements of the photodetector device.

Abstract: The present disclosure provides a technique which makes it possible to evaluate a state of a cell aggregation of one or more spheroids. In the culture state determination device according to the present disclosure, a plurality of light sources sequentially illuminate a plurality of cell aggregations put on an image sensor. The image sensor acquires captured images of the plurality of the cell aggregations each time when the plurality of the light sources illuminate the plurality of the cell aggregations. Control circuitry extracts a region including an image of the cell aggregation in the captured image; generates three-dimensional image information of the region using a plurality of the captured images; extracts an outer shape of the cell aggregation and a cavity part inside the cell aggregation using the three-dimensional image information; calculates a first volume that is a volume based on the outer shape of each of the cell aggregation and a second volume that is a volume of the cavity part based on the cavity part of each of the cell aggregation in the three-dimensional image information; and determines a culture state of the cell aggregations using the first volume and the second volume.

Abstract: An image generating apparatus is provided with: first and second light sources that illuminate a material; an image sensor on which the material is disposed; a mask which includes a light-transmitting part that transmits light and a light-blocking part that blocks light, and which is positioned between the image sensor and the first and second light sources; and a light and dark image processing unit. The image sensor acquires first and second images of the material when illuminated by the first and second light sources, respectively. The light and dark image processing unit derives a difference between a luminance value of a pixel included in the first image and a luminance value of a pixel included in the second image at the same position as the pixel included in the first image, and thereby generates a third image of the material.
