A technique capable of providing a user with information obtained by OCT imaging in a useful way, particularly for assisting in assessment of an embryo effectively. The image processing method includes acquiring original signal data indicating an intensity distribution of signal light from each position in three-dimensional space including a cultured embryo obtained by optical coherence tomography imaging, generating spherical coordinate data based on the original signal data, the spherical coordinate data indicating a relationship between each position in the three-dimensional space represented using spherical coordinates having an origin set inside the embryo and the intensity of the signal light from the position, and outputting the intensity distribution of the signal light as a two-dimensional map based on the spherical coordinate data using two deflection angles of the spherical coordinates as coordinate axes.

Image processing method for a computer to assist a user in assessment of a cultured embryo

A data processing method that is suitable for obtaining quantitative information from data obtained by OCT imaging. The image processing method includes acquiring original image data corresponding to a three-dimensional image of a cultured embryo obtained by optical coherence tomography imaging of the embryo and executing a region segmentation the three-dimensional image into a plurality of regions on the basis of the original image data. In the region segmentation, a local thickness calculation is performed on the three-dimensional image to determine an index value indicating a size of an object included in the three-dimensional image, the three-dimensional image is segmented into a region indicated by the index value greater than a predetermined first threshold and a region indicated by the index value less than the first threshold, and each of the regions resulting from the segmentation is further segmented by the watershed algorithm.

A technique for automatically and accurately determining life or death of cells in a sample prepared without any labeling, not relying on the subjectivity of a determiner, is intended. A fluorescent specimen in which respective fluorescence generation modes in response to excitation light are different from each other between a living cell and a dead cell is prepared, and fluorescence imaging of the fluorescent specimen is performed. Bright field imaging of the fluorescent specimen is performed, and respective positions of the living cell and the dead cell are specified from a fluorescent image. Image objects in a bright field image, which are located at positions corresponding to the specified positions of the living cell and the dead cell are extracted as a living cell object and a dead cell object, respectively, and a classifier is constructed through machine learning using supervisor data including respective feature vectors of the extracted objects.

Prior to performing download play, it is checked whether or not it is necessary to update firmware of a slave apparatus. When it is necessary to update the firmware of the slave apparatus, a firmware update program is transmitted from a master apparatus to the slave apparatus, and the firmware of the slave apparatus is updated in accordance with the firmware update program. Thus, it is possible to update basic software by a novel method.

Communication system, information processing apparatus, computer-readable storage medium, and communication method

A preliminary image is obtained by irradiating illumination light, whose light quantity distribution is set at a standard state, to a specimen obtained by injecting fluid into a well from an illuminator capable of arbitrarily setting the light quantity distribution, for example, by a liquid crystal shutter, and a luminance distribution of the preliminary image is detected. As a result, luminance nonuniformity in the preliminary image is canceled by performing imaging with a light quantity distribution of illumination light to be incident on the well set such that an incident light amount is larger in a part with lower luminance.

Imaging apparatus and imaging method

Prior to performing download play, it is determined whether or not a slave apparatus program has been already stored in an internal memory of a slave apparatus. When not stored yet, the slave apparatus program is transmitted from a master apparatus to the slave apparatus, and stored in the internal memory of the slave apparatus. When already stored, the slave apparatus program is not transmitted from the master apparatus to the slave apparatus. Then, multiplay is performed by performing mutual communication between the master apparatus operating in accordance with a master apparatus game program and the slave apparatus operating in accordance with a slave apparatus game program. Thus, time and effort for receiving the same application program more than once are omitted, and it is possible to efficiently start a communication process.

In a first information processing apparatus, data in a first format is stored. Further, the data in the first format is transformed into a code image by using a predetermined encoding mode. Moreover, code image data in a second format is generated by combining the code image with the data in the first format. In a second information processing apparatus, predetermined information processing is performed based on the data in the first format. In a third information processing apparatus, the code image is displayed, by a first display device, based on the code image data in the second format.
