Abstract: Provided is a fetal heart rate variability monitoring device capable of easily determining a fetal condition. A fetal heart rate variability monitoring device includes a processing unit and a display unit that acquire a fetal heart rate and display a fetal heart rate diagram showing the fetal heart rate over time, an LTV and STV conversion processing unit that calculates STV and LTV from the fetal heart rate, and an event input unit that can designate a predetermined period on the fetal heart rate diagram. The processing unit and the display unit have a function of issuing notification of the STV and LTV in the predetermined period calculated by the LTV and STV conversion processing unit when the predetermined period is designated by the event input unit.

Abstract: There are provided a maternal and fetal monitoring device and a display device for monitoring device including fetal heart rate acquisition means configured to acquire a fetal heart rate, labor pain intensity acquisition means configured to acquire a maternal labor pain intensity, fetal bioelectric signal acquisition means configured to acquire a fetal bioelectric signal, and display means capable of simultaneously displaying a cardiotocogram that displays the fetal heart rate and the labor pain intensity side by side on the same time axis over time as a graph and a fetal bioelectric signal diagram displaying the fetal bioelectric signal, and optimizing and displaying, together with the cardiotocogram, the fetal bioelectric signal diagram and the like closely related to these pieces of information.

Abstract: Provided are a fetal electrocardiographic signal processing method and a fetal electrocardiographic signal processing device that can appropriately select a signal reliably including a fetal electrocardiographic component from a plurality of signals separated by independent component analysis with reference.

Abstract: Provided is a game device for displaying a screen showing a state in which a virtual three-dimensional space having an object placed therein is viewed from a given viewpoint, the game device including: a first image creating unit for creating a first image representing the state in which the virtual three-dimensional space is viewed from the given viewpoint; a coordinate acquiring unit for acquiring three-dimensional coordinates of a light source set in the virtual three-dimensional space; a second image creating unit for creating a second image representing diffusion of light from the light source based on the three-dimensional coordinates of the light source; and a display control unit for displaying a screen obtained by synthesizing the first image and the second image with each other.
