The holographic storage medium, which contains binary information in the form of at least one two-dimensional data page, is illuminated by means of a laser beam bundle and the retrieved data page is read out by means of the image sensor, for which purpose the latter is provided with an activatable area having a multiplicity of pixels. It achieves the object of configuring a method of this type in such a way that the read-out of the information is accelerated with a number of pixels remaining the same. For this purpose, the activatable area of the image sensor is subdivided into different regions which are in each case assigned to a region having a specific intensity of the light beam. In this case, a longer exposure time and/or a higher sensitivity are/is determined for regions assigned to regions having lower intensity than for regions assigned to regions having a higher intensity.

    Abstract: A method and an apparatus to accept line-scan data sets at a camera rate from a line-scan camera and resample the line-scan data sets to produce resampled line image data sets at a desired sampling distance. Each line-scan data set is of an object imaged for a fixed exposure time and moving at a relative speed in relation to the line-scan camera. The method includes accepting the line-scan data sets at the camera rate from the line-scan camera, accepting a measure of the relative speed between the line-scan camera and the object being imaged by the line-scan camera, and resampling the line-scan data sets to produce resampled line image data sets at the desired sampling distance. The resampling is a function of the camera rate, the measure of relative speed and the desired sampling distance. The resampling adjusts for the variations in relative speed to produce faithfully exposed data.

When the blocks to be coded are scanned, probabilities that non-zero coefficients occur are obtained from the at least one selected reference block, and the scanning order is determined in descending order starting from the highest probability. Here, the scanning order is generated to be a zigzag scanning order if the probabilities are identical. The optimal scanning method increases signal compression efficiency.

  • Patent number: 7145952
    Abstract: A discrete cosine transform (DCT) level enhancement to Motion Picture Experts Group (MPEG) video encoding is described that results in a more concise bitstream than MPEG encoding without the enhancement. One degree of freedom provided by the MPEG encoding specifications is whether a frame- or field-based DCT operation will be used. In the field-based DCT operations, luminance sub-blocks are built from even or odd rows of the original image, which correspond to the top and bottom fields in field-based video. This allows the encoder to take advantage of the higher correlation between rows for the same field, especially in field-based video with a high level of motion. In one embodiment, both field- and frame-based DCT operations are performed and the results are quantized. On a macroblock-by-macroblock basis, the option that results in the fewest non-zero coefficients is selected and those coefficients are used for run-time encoding.

    Abstract: An image sensor having an integrated address controller for use in an electronic camera. Providing both functions on a single integrated circuit reduces the number of external pins and external circuitry required to process an image. The integrated address controller also provides several addressing modes allowing for programmable format data transfer from the image sensor. This integrated controller not only allows addressing the sensor array in a raster scan, but it also allows other addressing modes including block addressing (useful for block based compression methods like JPEG, MPEG or H.261) and region addressing (by which one could implement pan and tilt functions). Thus, this sensor and address controller combination provides data in the format required for higher level functions, as opposed to forcing the user to convert raster scan to an appropriate format using complicated external circuitry.

  • Patent number: 5995152
    Abstract: A video monitor including logic circuitry which superimposes a high frequency periodic wave on the vertical positioning provided by the monitor's vertical deflection plates in low resolution modes. The waveform operates to slightly and periodically adjust the electromagnetic output of the vertical deflection plates, enabling the electron beam to pass through the shadow mask in a plurality of locations. In low resolution modes, the electron beam passes through additional holes in the shadow mask line that formerly presented a black stripe, thus enabling additional pixels to be struck and causing the black lines to disappear. This creates the appearance of a larger electron beam without changing the electron gun or adding additional deflection hardware.

  • Patent number: 5933543
    Abstract: A method and system that obscures image features in a region of interest designated by a user. An operator designates a special shaped region of interest and a computer convolves a specially designed kernel with the image data in the region. The kernel is designed to pull features outside the region into the region while combining the information within the region with the information pulled from outside. The kernel can be designed to correspond to the shape of the region for efficient computation. Once the region of interest is obscured the image is printed resulting in a print that does not include undesirable features.

  • Patent number: 5861914
    Abstract: A system for representing information data has a scanning device for scanning information data and including a unit for interrogating the information data and formed as a movable interrogating element unit for forming a main flow of impulses corresponding to the information data which have been interrogated by the interrogating element, a unit for forming commands in response to the impulses for moving the interrogating element successively in direction selected from more than two directions with equal probability, a unit for providing deviation of the interrogating element by a limit of a field, and a unit located downstream of the deviation unit for introducing an additional flow of impulses randomly distributed in time, so that the interrogating element can move in response to the impulses of the additional flow and deviate also at any point of the field.

  • Patent number: 5774178
    Abstract: A multiple-beam field sequential color (FSC) display system is provided for receiving a stream of digitized single-beam image data to display a color image by employing a plurality of CRT guns to project multiple beams on a monochromatic CRT screen followed by converting a monochromatic refection from the CRT screen to the color image by using a liquid crystal color system (LCCS). The multiple-beam display system includes a multiple-beam image data memory which includes a plurality of data-banks. The multiple beam display system further includes an image data rearranging processor for rearranging and storing the plurality of digitized single-beam image data in the multiple beam-image data memory according to a pre-designated multiple-beam sequence in each of the data-banks.
