  • Patent number: 11966072
    Abstract: A planar light source device includes a plurality of light sources that is independently drivable, a first light guide to emit light incident from the first light source from an emitting surface in an emitting direction, a second light guide that is contained in a second light emitting region adjacent to a first light emitting region containing the first light guide and emits light incident from a second light source from the emitting surface in the emitting direction, and a partition frame having a partition wall that is positioned between the first light guide and the second light guide, partitions the first light emitting region and the second light emitting region, and is provided with a gap from the emitting surface of the first light guide, in which an angle formed by a wall surface and a bottom face of the partition wall is an acute angle.

  • Patent number: 11314991
    Abstract: An information display method includes converting P (P?2) high-dimensional data respectively obtained from P images each tagged with a label representing a result of classification into one of a plurality of classes to respectively acquire P low-dimensional data, generating a plot diagram including P plot points obtained by visualizing the P low-dimensional data each depending on the classification result, generating auxiliary information corresponding to a base point set as one of the plot points included in the plot diagram and N (1?N<P) reference points respectively set as the plot points corresponding to the N low-dimensional data extracted from among the low-dimensional data, belonging to a same class as a class to which the base point belongs, among the P low-dimensional data, and generating a display image including the plot diagram to which the auxiliary information is added.

  • Patent number: 11295489
    Abstract: An information presentation device according to an embodiment includes a contour extraction unit, an abstraction processing unit, and a contour correction unit. The contour extraction unit extracts a contour of each structural object included in data showing a layout of a plurality of structural objects. The abstraction processing unit abstracts a contour of each structural object extracted by the contour extraction unit and draws the abstracted contour on a plane grid surface in which grid lines in two directions orthogonal to each other are drawn. The contour correction unit corrects, among contour lines to constitute a contour abstracted by the abstraction processing unit, a contour line deviating from both of the grid lines in the two directions so as to match a grid line in at least one direction of the grid lines in the two directions.

  • Patent number: 11151763
    Abstract: An information presentation device includes a plot unit, a histogram generation unit, and a visual information generation unit. The plot unit plots a plurality of values included in each of a plurality of pieces of multidimensional data on a plurality of axes in a parallel coordinate plot coordinate system. The histogram generation unit divides each of the plurality of axes into a plurality of sections, and generates a plurality of histogram bars each of which corresponds to the number of values plotted in each section in the plurality of sections. When one or more values are selected as selected values, the visual information generation unit generates visual information with which the ratio of the number of selected values to the total number of values contained in any one histogram bar out of the respective histogram bars generated by the histogram generation unit can be identified.
