Abstract: A layered body includes: a substrate; and an oxide portion positioned on the substrate. An oxide that constitutes the oxide portion contains at least two or more rare-earth elements: silicon; and oxygen. The oxide that is contained in the oxide portion exhibits a diffraction peak derived from a (004) plane at a position of 2?=51.9°±0.9° in an X-ray diffraction pattern, and has an apatite crystal structure. The ratio of linear expansion coefficient of the oxide that constitutes the oxide portion in an a-axis direction relative to linear expansion coefficient of the substrate is 0.15 or more and 1.45 or less.

Abstract: A processing device generates a marker image to use as a reference for correcting a shape of a projection image projected on a projection surface from a projector, takes a taken image of the projection surface using the imaging device from an imaging position different from an observation position from which the projection surface is observed, generates a parameter for reducing a distortion of the projection image based on the marker image included in the taken image, displays an area image representing a range wherein projection can be performed on the projection surface on the display device, disposes a video content at an indicating position in the area image with an input to the input device, generates an original image including the video content, and corrects the original image thereby generating an input image for input to a projector configured to project the projection image.

Abstract: A display control method includes receiving, by a first terminal device, operation for selecting a first terminal mode, which is a mode used by the first terminal device, among a plurality of modes designating a range of an image, outputting, by the first terminal device, a first image, which is an image in a first range, designated by the first terminal mode among images generated by the first terminal device, receiving, by a second terminal device, operation for selecting a second terminal mode, which is a mode used by the second terminal device, among the plurality of modes, outputting, by the second terminal device, a second image, which is an image in a second range, designated by the second terminal mode among images generated by the second terminal device, and displaying, by a display device, an image in which the first image and second image are side by side.

Abstract: A display control method includes displaying a first small image generated by shrinking a first image generated by an application program, on an actual display provided in an output device, receiving an operation on the first small image, drawing, on a virtual display, a second image generated by the application program executing processing corresponding to the operation on the first small image, displaying the second image drawn on the virtual display, using a display device, and displaying a second small image generated by shrinking the second image, on the actual display.

Abstract: An information processing device functioning as a video editing device editing a video to be projected by a projector includes a display control unit, an acquisition unit, and a decision unit. The display control unit causes a display device of a touch panel to display an editing screen including a video display area where a video to be projected by a projector is displayed. The acquisition unit acquires, from the projector, information representing an aspect ratio of a projected video projected by the projector. The decision snit decides the video display area according to the aspect ratio represented by the information acquired by the acquisition unit.

Abstract: In a method of controlling a projector for displaying a whole image having partial images arranged based on image information supplied from an image supply device in cooperation with a projector, there are included the steps of displaying the partial image based on a part of the image information supplied from the image supply device, outputting the image information to the projector for displaying the partial image based on another part of the image information, obtaining configuration information related to the arrangement of the partial images, deciding overall resolution as the resolution for displaying the whole image based on the configuration information obtained, and storing the overall resolution to a resolution storage section for storing the resolution to be given to the image supply device as a notice.

Abstract: An image supply apparatus that transmits data to an image display apparatus includes: a control section; and a storage section that stores video files, wherein the control section includes the functions of receiving specification information indicating video reproduction performance of the image display apparatus, accepting selection of a video file to be transmitted to the image display apparatus from the storage section, acquiring attribute information indicating an environment necessary for reproducing a video from the selected video file, comparing the specification information and the attribute information to determine whether or not the image display apparatus can reproduce the video file, outputting a warning when it is determined that the image display apparatus cannot reproduce the video file, transmitting data of the video file to the image display apparatus when it is determined that the image display apparatus can reproduce the video file.

Abstract: An image supplying method includes the steps of: transmitting encoded video data including a key frame that is encoded by an inter-frame encoding process; receiving a seek operation and acquires a first play point in a desired seek position of the encoded video data; determining a search range including the acquired first play point; searching for key frames from the determined search range; determining a position of a key frame having a shortest distance from the first play point as a second play point in a case where the key frame is detected from the search range by the key frame searching unit; and transmitting the encoded video data from the key frame corresponding to the determined second play point.
