Abstract: Disclosed herein is an image pickup apparatus, including: an image pickup lens; a lens array disposed on an image formation plane of the image pickup lens; an image pickup device adapted to receive a light ray passing through the image pickup lens and the lens array to acquire picked up image data; and an image processing section adapted to carry out an image process for the picked up image data; the image processing section including a viewpoint image production section adapted to produce a plurality of viewpoint images based on the picked up image data, and an image synthesis processing section adapted to synthesize two or more viewpoint images from among the viewpoint images.

Abstract: A residual picture is produced and encoded that is a residual picture that is a residual signal between a picture to be coded that is an input moving-picture video signal to be subjected to coding and a predictive picture produced from a reference picture that is a local decoded video signal for each of a plurality of rectangular zones, each composed of a specific number of pixels, into which a video area of the moving-picture video signal is divided. A boundary condition of each of a plurality of borders is obtained between the rectangular zones and another plurality of rectangular zones adjacent to the rectangular zones, and a border, of the reference picture, having a boundary condition that matches the boundary condition, is found by motion-vector search in the reference picture, and border motion-vector data is generated that is data on a motion vector from a border of the rectangular zone in the picture to be coded to the border of the reference picture thus found.

Abstract: A method for receiving a broadcasting signal and a broadcasting signal receiver are disclosed. Even when a cell is changed while an emergency alert is output, the emergency alert can be continuously output using emergency alert table information included in the broadcasting signal and channel information of the cell. The emergency alert table information may include a cell identifier and the channel information of the cell may include virtual channel information of the cell.

Abstract: A system and method comprise defining a current rectangular region of the image bitmap, quantifying spectral characteristics of the current rectangular region, dividing the current rectangular region into four rectangular sub-regions in response to the spectral characteristics being greater than a predetermined threshold value, tagging the current rectangular sub-region as a terminal rectangular region in response to the spectral characteristics being less than or equal to the predetermined threshold value, tagging each rectangular sub-region as a terminal rectangular region in response to a size of the rectangular sub-region being less than or equal to a predetermined threshold size, defining one of the non-terminal rectangular sub-regions as the current rectangular region and repeating the above until all rectangular regions are tagged terminal, and determining color characteristics for each of the terminal rectangular regions.

Abstract: Methods and apparatus for generating images, compressing image data, decompressing image data, and processing the decompressed image data so that it can be used by a rendering circuit of a device, e.g., a set top box, are described. Images are generated in the native format used by the rendering circuit of the device which will ultimately control the display of the image avoiding the need to perform processing associated with converting color component information from one format to another. Uncompressed image data is arranged in a file with color component values being grouped separately from alpha values to facilitate compression by a standard file compression technique. The file is compressed using a conventional file compression operation. The compressed image file is decompressed when needed and the alpha data and color component data is reorganized so that the color component values and alpha value(s) corresponding to individual pixels are grouped together.

Abstract: The color of a pixel is represented in a pixel storage word, wherein color coordinate data and intensity data are coded separately in two fields of the pixel storage word, the color field and the intensity field. This permits a range of colors to be represented in a relatively small number of bits. In one embodiment of the invention, each of the three color coordinates of an input color is coded separately. The coded color components are concatenated and placed in a coded color field of the pixel storage word. In another embodiment of the invention, the color coordinate data is encoded as a color index, a binary value which maps to color coordinate data according to a predefined color table. Intensity data is also encoded with a binary value. The coded intensity can represent the intensity directly, or can be an index to intensity data stored in a predetermined intensity table.

Abstract: A video encoder able to adjust output levels and able to more effectively utilize performances of later devices, provided with a level adjustment circuit for adjusting output levels of an input luminance signal, color signal, and composite video signal by adding DC offset in accordance with a value set in a register or the like in advance and outputting the same to a display device, and an image processing system using the same.

Abstract: A mechanism for splicing advertisements, local programming and the like into a digital video transport stream is provided. In order to achieve proper splicing, an appropriate number of frames is inserted between bitstreams to properly close a GOP of the first bitstream into which a second bitstream carrying the spliced content is inserted. Program clock references (PCRs) of the bitstreams are adjusted as necessary in order to force continuity between the bitstreams. For inserting advertisements, the PCR of the program stream and ad stream can be tracked, and the PCR of the program stream can be used both before and after splicing. For local program insertion (which are typically substantially longer than advertisements), the PCR of the local program can be used, after adjustment thereof with an offset to maintain continuity at the splice point. The PTS and/or DTS of the inserted bitstream can be modified to keep them continuous at the splice point for both video and audio streams.

Abstract: A method and apparatus for storing a macroblock from a video data stream is disclosed. A macroblock is received, the macroblock having a plurality of blocks corresponding to a plurality of color space components and having a width defined by a plurality of pixels. According to a first aspect of the present invention, the macroblock is stored in a vertical strip format. According to a second aspect of the present invention, the contents of the plurality of blocks are interleaved. According to a third aspect of the present invention, the contents of the plurality of blocks are interleaved and the macroblock is then stored in a vertical strip format.
