A camera outputs to a host terminal a moving image for display on a display. An image acquisition unit acquires an unprocessed image captured using an imaging element. A simple demosaic processing unit performs a demosaic process on the unprocessed image. A pyramid filter unit converts the unprocessed image into a plurality of reduced images whose resolutions vary in stages. An image transmission unit is provided with a selection unit for selecting a part of the unprocessed image as a specific part and also selecting any one of the plurality of reduced images as a specified reduced image. The specific part of the unprocessed image and the specified reduced image that have been selected are transmitted to a host terminal by a communication unit for a further image process.

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.

A compression format identifying unit identifies the compression format of image data stored in a main memory. A transfer function determining unit determines a transfer function in accordance with the compression format of a tile image thus identified. A convolution operation unit subjects a modification request signal and the transfer function thus determined to convolution operation so as to generate a modification direction signal. A read ahead processor reads a tile image from the main memory using the modification request signal, decodes the image, and writes the decoded image in a buffer memory. A display image processor generates a display image using the modification direction signal.

An image hierarchy generation unit reads image data stored in a hard disk drive, generate images with a plurality of resolutions, and hierarchizes the images. An image dividing unit divides the image in each layer into tile images. A redundancy detection unit analyzes the image in each layer so as to detect redundancy between images within the same layer or images from different layers. A tile image reference table creates a tile image reference table that maps area numbers to tile numbers, in view of the redundancy. An image file generation unit creates an image file that should be ultimately output and includes image data and the tile image reference table.

A timing signal generation unit of a content playback device generates a shutter control signal requesting the opening or closing of a shutter of a lens among one or more lenses of a pair of shutter glasses worn by a user viewing a display panel adapted to display content, and a backlight control signal requesting a backlight of the display panel to be turned on at least when the shutter is open. A transmitter unit transmits the shutter control signal to the shutter glasses. The timing signal generation unit changes at least one of the timing of turning on the backlight or the timing of opening the shutter of the lens of the shutter glasses.
摘要:
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.

A main memory stores M-bit gradation image data (M is a natural number). A correction function generating unit generates a correction function in N-bit gradation (N is a natural number, N>M) from image data. A display image generating unit generates display image data using a correction function generated by the correction function generating unit. The display image generating unit uses a correction function so as to generate display image data resulting from correcting image data obtained by decoding compressed image data in M-bit gradation with the restriction of M-bit quantization.
摘要:
Frames of a moving image are configured as a hierarchical structure where each frame is represented with a plurality of resolutions. Some layers are set as original image layers, and the other layers are set as difference image layers in hierarchical data representing a frame at each time step. In the case that an area is to be displayed in the resolution of the difference image layer, to respective pixel values of a difference image of the area, respective pixel values of an image of a corresponding area retained by the original image layer of lower resolution, the image enlarged to the resolution of the difference image layer, are added. A layer to be set as a difference image layer is switched to another layer as time passes.

Links are set among three hierarchical data and one moving image data. When a display area overlaps with a first link area while an image is being displayed by using first hierarchical data, switching to display by use of the 0-th hierarchical level of the second hierarchical data is made. When the display area overlaps with a second link area while an image is being displayed by using the second hierarchical data, switching to display by use of the 0-th hierarchical level of the third hierarchical data is made. The link destination of another link area is the moving image data and moving image reproduction is started as a result of zoom-up of this area. The hierarchical data are held on the client terminal side and the data existing on the other side of a switching boundary are transmitted to the client terminal in a data stream format.

In an image processing apparatus, an image pickup unit takes images of an object including the face of a person wearing the glasses by which to observe a stereoscopic image that contains a first parallax image and a second parallax image obtained when the object in a three-dimensional (3D) space is viewed from different viewpoints. A glasses identifying unit identifies the glasses included in the image of the object taken by the image pickup unit. A face detector detects a facial region the face of the person included in the image of the object taken by the image pickup unit, based on the glasses identified by the glasses identifying unit. An augmented-reality special rendering unit adds a virtual feature to the facial region of the face of the person detected by the face detector.
