  • Publication number: 20210208727
    Abstract: When an application displays image straddling display units (110-1 and 110-2), a coordinate conversion unit (120) uses a predetermined operation to transform the physical coordinates indicating the position at which a display unit (110-1 or 110-2) senses contact to virtual coordinates and supplies the virtual coordinates. A coordinate notification unit (130) notifies an application (140) of the physical coordinates at which contact was sensed when the application is displaying the image on one of the display units (110-1 or 110-2) and notifies the application (140) of the virtual coordinates supplied by the coordinate conversion unit (120) when the one application is displaying the image straddling the display units (110-1 and 110-2).

  • Publication number: 20210211942
    Abstract: A communication system is disclosed in which communication resources are dynamically partitioned into a plurality of slices, each slice having at least one associated network-level performance requirement. A network-level performance requirement is translated into cell-level resource requirement(s) for determining, based on the cell-level resource requirement(s), whether to admit a slice instance. When the slice instance is admitted, information identifying the cell-level resource requirement(s) for the slice instance is provided to a scheduler function. The cell-level resource requirement(s) for a given slice instance may be used to determine an associated packet delivery deadline and entitled resource amount before deadline. The scheduler function allocates communication resources to each admitted slice based on an earliest-deadline-first method.

    Abstract: A gradient calculation unit calculates an image gradient on a pixel-by-pixel basis in each of a plurality of images. A scale search unit calculates a scale score based on degree of spatial frequency components for each pixel in each of the images. A gradient score calculation unit calculates, for each pixel, a gradient score on the basis of the image gradient and the scale score. A gradient finalization unit calculates, using the gradient score and, as a target gradient, an image gradient of each pixel in a combined image. On the basis of the target gradient, a coefficient calculation unit calculates, for each pixel of the combined image, a coefficient of base vectors constituting a preset base vector group in the combined image. A combining unit generates the combined image through linear combination of the base vectors based on the calculated coefficients.
