Abstract: A position indicating device includes a housing, a position indicator which, in operation, indicates a position, a first pressure sensor which, in operation, detects a pressure applied to the position indicator, a second sensor which, in operation, detects a second pressure applied to the housing, a first communication circuit which, in operation, transmits the pen pressure detected by the pen pressure sensor, and a second communication circuit which, in operation, transmits the gripping force detected by the gripping force sensor. The position indicating device enables control of a line width and transparency in a preferable manner even when there is no actual touch surface.

Abstract: A position indicator indicates a position on an input surface of a position detecting sensor and indicates a position in a three-dimensional space. The position indicator incudes: a casing, a position indicating part that is disposed at one end of the casing, and a tracker which, in operation, causes an external device to detect the position in the three-dimensional space. The position indicating part, in operation, indicates the position on the input surface of the position detecting sensor. A position of the tracker and a position of the position indicating part are in a specific positional relation.

Abstract: A sensor includes a first substrate on a back side of a display panel, a first coil extending in a first direction at a predetermined angle between 0 and 90 degrees with respect to a long-side direction of the first substrate and including a first long-side portion provided with first and second end portions, a second coil including a second long-side portion extending in a second direction, a first leader line including a first end and a second end, wherein the first end is connected to the first end portion, and the second end is connected to wiring on a second substrate arranged to extend at a right angle toward the outside of the sensor from one side of the first substrate, and a second leader line including first end connected to the end portion and a second end connected to the wiring on the second substrate.

Abstract: An input device includes: a sensor; a detection circuit which, in operation, detects a first indicated position indicated by an electronic pen in a two-dimensional space in accordance with transfer of a signal between the electronic pen and the sensor; one or more processors; and one or more memory devices storing instructions that, when executed by the one or more processors, cause the one or more processors to: detect a second indicated position indicated by the electronic pen in a three-dimensional space, and generate position information of the electronic pen in the two-dimensional space or the three-dimensional space based on the second indicated position and first indicated position. The input device enables a position indicated by the electronic pen and a pen posture of the electronic pen in the three-dimensional space to be detected in a satisfactory manner in view of precision and response speed.

Abstract: A rendering device that renders a three-dimensional object displayed in a virtual reality space on a display includes a processor and a memory storing instructions that, when executed by the processor, cause the processor to render the 3D object as a 3D object of 3D displaying in a virtual reality space coordinate system, render the 3D object as a 3D object of 2D displaying in a plane coordinate system, and update displaying of the display based on a result of the 3D object being rendered as the 3D object of 3D displaying in the virtual reality space coordinate system and a result of the object being rendered as the 3D object of 2D displaying in the plane coordinate system. The rendering device enables intuitive drawing with high accuracy in the virtual reality space.

Abstract: A spatial position indication system includes an electronic pen, an indicated position detecting circuit, a spatial position detecting circuit, and a selecting circuit. The indicated position detecting circuit detects a position of the electronic pen at an input surface or a hover region over the input surface. The spatial position detecting circuit detects the position of the electronic pen in a spatial region including at least a part of the hover region separately from and independently of the indicated position detecting device circuit. Based on output from the indicated position detecting circuit and the spatial position detecting circuit, the selecting circuit performs selection control so as to use output from the indicated position detecting circuit or the spatial position detecting circuit according to a separation distance of the electronic pen from the input surface when a drawing image to be displayed on a display device is generated.

Abstract: A method and system for generating a detector to detect a dominant color of an image is provided. A dominant color system trains a detector to classify colors as being dominant colors of images. The dominant color system trains the detector using a collection of training images. To train the detector, the dominant color system first identifies candidate dominant colors of the training images. The dominant color system then extracts features of the candidate dominant colors. The dominant color system also inputs an indication of dominance of each of the candidate dominant colors. The dominant color system then trains a detector to detect the dominant color of images using the extracted features and indications of dominance of the candidate dominant colors as training data.

Abstract: A method and system for classifying an image as a photograph or a graphic based on a ranked prevalent color histogram feature or a ranked region size feature is provided. The prevalent color histogram feature contains counts of the colors that are most prevalent in the image sorted in descending order. The region size feature contains counts of the largest regions of the image sorted in descending order. The classification system then classifies the image based on the ranked prevalent color histogram feature and/or the ranked region size feature using a previously trained classifier.
