  • Patent number: 8917286
    Abstract: When a single page of a newspaper article or a magazine is displayed using hierarchical data, a guidance area (indicated by a line in the hierarchical data) for each article is defined in a scenario definition file. A plurality of guidance areas are defined in the layer below, i.e., the layer having a resolution of a level that allows characters to be legible, so that the viewer can track the article from start to end. The displayed image is initially guided to the guidance area upon a user request for enlargement. Upon a further request for enlargement, the displayed image is guided to the guidance area at the head of the article. When the user having read the sentence in the guidance area provides an input by indicating a direction or pressing a predetermined button, the displayed image is guided to the guidance area showing the continuation of the sentence.

  • Patent number: 8878869
    Abstract: Compressed image data of different resolutions stored in a hard disk drive is divided into blocks of substantially regular sizes. A determination is made as to whether a required block is stored in the main memory at predefined time intervals. If the block is not stored, the block is loaded into the main memory. Subsequently, the loaded compressed image data is referred to so that data for an image of an area required for display or for an image of an area predicted to be required is decoded and stored in a buffer memory. Of the images stored in a buffer area, i.e. a display buffer, the image of a display area is rendered in a frame memory. The display buffer and the decoding buffer are switched depending on the timing of completion of decoding or the amount of change in the display area.

  • Patent number: 8670046
    Abstract: A user enters an input for selecting an image-capturing mode. The user then captures the image of a target with a desired zoon factor as a target image. An image-capturing device determines a zoom factor for an image to be captured starting from the target image and then captures an image while zooming out to the determined zoom factor. A process of changing the zoom factor and capturing an image is repeated until the smallest zoom factor among determined zoom factors is used. When image capturing of an image of the smallest zoom factor is completed, metadata is created that includes the respective zoom factors of images and relative position information of the images, and the metadata is stored in a memory unit in relation with the data of the captured images.

  • Publication number: 20130167031
    Abstract: Moving image data is delivered from an image provider server. A hierarchical data generation device decodes the moving image data and generates data for the moving image representing each frame in a plurality of resolutions, by reducing frames included in the moving image in a single or multiple stages. A decoder reads only data for a layer in the hierarchical data for each frame, the layer being determined by a resolution requested for display, and decodes the read data. This produces a series of frames representing frames in a requested resolution. A display device displays the frames so that the moving image is displayed in the requested resolution.

  • Publication number: 20120313960
    Abstract: A parallax representation unit in a displayed image processing unit uses a height map containing information on a height of an object for each pixel to represent different views caused by the height of the object. A color representation unit uses, for example, texture coordinate values derived by the parallax representation unit to render the image, shifting the pixel defined in the color map. The color representation unit uses the normal map that maintains normals to the surface of the object for each pixel to change the way that light impinges on the surface and represent the roughness accordingly. A shadow representation unit uses a horizon map, which maintains information for each pixel to indicate whether a shadow is cast depending on the angle relative to the light source, so as to shadow the image rendered by the color representation unit.
