  • Patent number: 10115003
    Abstract: An image processing apparatus comprises a normalisation module operatively connected across a bus to a memory storing an image in which a region of interest (ROI) has been identified within the image. The ROI is bound by a rectangle having a non-orthogonal orientation within the image. In one embodiment, the normalisation module is arranged to divide the ROI into one or more slices, each slice comprising a plurality of adjacent rectangular tiles. For each slice, the apparatus successively reads ROI information for each tile from the memory including: reading a portion of the image extending across at least a width of the slice line-by-line along an extent of a slice. For each tile, the apparatus downsamples the ROI information to a buffer to within a scale SD<2 of a required scale for a normalised version of the ROI.

    Abstract: When a digitized broadcast is recorded in a storage medium, a required capacity of the storage medium is firstly calculated on the basis of a bit-rate of digitized broadcast data and a recording time which is known in advance. If the remaining capacity of the storage medium is smaller than the required capacity of the storage medium, for example, a frame rate decimation and pixel reduction are performed upon a broadcast to be newly stored, a re-encoding processing is performed for the broadcast and then the resultant broadcast is stored in the storage medium. If the remaining storage capacity of the storage medium is larger than the required capacity of the storage medium and thus remains, a frame interpolation and pixel interpolation are performed for the broadcast to be stored and then a re-encoding processing is performed for the resultant broadcast in order to improve its image quality. As a result, recording of the broadcast data in the storage medium can be ensured.

  • Patent number: 7307635
    Abstract: A frame buffer stores X pixels per line and Y lines and is read using a burst of B pixels. The un-rotated image is rotated by 90 degrees for display by writing and reading pixels from a line buffer. The line buffer stores a block of B*Y pixels. The frame buffer is logically divided into X/B blocks that are B pixels wide. Blocks are read from the frame buffer from the bottom line to the top with a burst of B pixels per line. An offset locate pixels to read in the line buffer. The offset is B for the first block, and increases by a factor of B for each block read, but wraps around modulo B*Y?1. Pixels for a next block are written into the line buffer to locations vacated as pixels are read out. The increasing offset re-orders the pixels for the rotated display order.

  • Patent number: 7253821
    Abstract: A novel special picture effect is to be achieved by a read address control system. To this ends, a special effect device includes an address signal generating unit 3 for generating a readout address signal for picture signals stored in a frame buffer 2 so that such a special effect is achieved in which a picture corresponding to the picture signals stored in said frame buffer is rotationally moved about an optional point, provided to the outer rim of a display area at the time of display, as the center of rotation, so as to disappear to outside the display area.

  • Patent number: 6801674
    Abstract: Circuit arrangements and methods for real-time image resizing and image rotation. Line buffers are used for storage of lines of pixel values for both resizing and rotation. A first one of the line buffers receives input pixel values, and the line buffers are coupled in a chain such that line buffer i receives pixel values from line buffer i−1. The lines of pixel values are moved from line buffer i to line buffer i+1 as the pixel values are processed for resizing or rotation.

  • Patent number: 6690731
    Abstract: A method for diagonal processing of video data includes separating diagonally arranged data from rectilinearly arranged data in a video stream, rotating the diagonally arranged data to a rectilinear position; and compressing the rotated diagonally arranged data by a rectilinear compression algorithm. Alternatively stated, the method includes recognizing diagonally arranged data in a video stream, processing the diagonally arranged data into rectilinear data, and compressing the rectilinear data by a rectilinear compression algorithm.

  • Patent number: 6674484
    Abstract: The two dimensional sample rate conversion capabilities of a video display system are used to produce three-dimensional effects. Linear and non-linear scaling is applied to a video image to convey a sense of depth. The three dimensional effects are used to increase the visual appeal of existing and new feature sets in display systems. A multi-faceted object representation, such as a representation of a cube or a pyramid, can be used to display different video images on each facet of the representation. By appropriately scaling each image on each facet, an impression of depth is achieved. The images on the different facets can be selected to represent different aspects of a common theme, such as datacast information related to a primary source of information. Channel changing on a television can be presented as a rotation of the multifaceted object.

  • Patent number: 6504551
    Abstract: The color of plural pixels making up a source video image is corrected by a computer 10, a hard disc device 20 and a picture processing device 30. The computer 10 functions as a parameter setting unit for setting plural parameters for designating the source color and the destination color and a computing unit for computing correction data for color correction from the source color to the destination color using the plural parameters set by the parameter setting unit. The hard disc device 20 stores the source video image and effects color correction in the picture processing device 30 for correcting the color of a pixel corresponding to the source color contained in the source video image to the destination color.

  • Patent number: 6346972
    Abstract: A video display apparatus has an on-screen display pivoting function in which, even when the user arbitrarily pivots the monitor of a computer system, the on-screen display is normally displayed. An on-screen display (OSD) generating section receives horizontal/vertical synchronizing signals and clock signals, and outputs first video signals in response to OSD control signals. A pivot circuit section receives the first video signals, stores a write address of the first video signals in a position-converting manner and in correspondence with a pre-set pivot write address, and converts the write address in response to the horizontal/vertical synchronizing signals and the clock signals so as to output the first video signals in the form of second video signals.

  • Patent number: 6307575
    Abstract: A display unit has an on-screen-display (OSD) control block for controlling display of OSD patterns on a screen together with a main image. The screen adjustment of the display unit is effected by a dedicated switch for effecting enlargement/reduction or movement of the effective screen area on the screen. The OSD control block enlarges/reduces or moves the OSD pattern by responding to the enlargement/reduction or movement of the effective screen area, thereby providing a visual scale for the enlargement etc. of the screen during the screen adjustment.

  • Patent number: 6239846
    Abstract: A digital video effects apparatus is arranged to generate a digital video effect by interpolating the values of parameters governing the effect, according to a given function, between time points corresponding to selected frames of a video signal and at which the parameters are fixed at selected values. The apparatus is organised in such a manner that the values of parameters are stored in exclusive timelines enabling the time points at which the parameter values are fixed to be adjusted without reference to other parameters governing the same video effect.
