  • Patent number: 9235878
    Abstract: The invention described here provides a novel method of preventing the loss of focus and range of colors when digital image files are expanded to a larger size. Unlike interpolation algorithms and algorithms using Fourier analysis to create new pixels, the present system uses a combination of pseudo-randomizing functions and user controlled edge detection to enhance edges initially softened by expansion using interpolation algorithms. The resulting images can be optimized to provide a superior approximation to what would be an accurate photographic representation at the larger image size. Furthermore, the flexibility in edge detection sensitivity allows the operator to strongly mitigate the structural artifacts produced by lossy compression algorithms such as the jpeg system and sampling errors widespread in very small images. As a result files as small as 200 kilobytes can be effectively expanded to 250 or even 500 megabytes in many cases.

  • Patent number: 8144078
    Abstract: A method and apparatus for controlling brightness, color and contrast in CRT monitors used in information handling systems. In accordance with the present invention, a viewing area on a CRT monitor is enhanced by applying appropriate signals directly to the grids in the CRT. In one embodiment of the present invention, appropriate voltage signals are applied to the G1 grid of the CRT. Parameter data is provided to the CRT using a DDC2/CI data channel, with the parameter data being based on the VESA MCCS command set. Utilizing the method and apparatus of the present invention, it is possible to achieve significantly greater brightness, color and contrast control in enhanced viewing areas displayed on a CRT monitor used in an information handling system.

  • Patent number: 8139059
    Abstract: Methods and systems for displaying an image as a virtual representation of an object based upon detected external light are described. An illustrative computer-implemented method includes steps of detecting the ambient light of an environment, such as a room, at a display surface. Data representative of the detected ambient light is processed to determine a direction of the detected light with respect to the display surface. An image is displayed on the display surface as a virtual representation of an object based upon the detected ambient light. Shadowing affects may be displayed to create the appearance that the virtual representation of the object casts a shadow on the display surface. Physical objects placed against or near to the surface of the display surface may also have images displayed on the display surface corresponding to shadows created by the ambient light.

  • Patent number: 8139856
    Abstract: An image processing apparatus, a computer readable medium and the like in which a dither effect in a neighborhood of a highlight area can be obtained easily and certainly. For this purpose, an image processing apparatus includes an inputting unit which inputs a pixel signal group representing a field image, an averaging unit (21-2 and 21-3) which performs a processing having an averaging effect among the pixel signal group input by the inputting unit, and an irregularizing unit (21-4) which irregularizes mutually continuous signal-values at least near a saturated level among the pixel signal group after having been processed by the averaging unit, into discontinuous signal-values.

  • Patent number: 8098953
    Abstract: An image processing apparatus for automatically improving the contrast of an input image that is obtained from a digital camera or the like, and obtaining a sharper and clearing image. A contrast improvement unit performs a contrast improvement process on the input image by comparing an object pixel in the input image with pixels in the surrounding area. An image combination unit combines the enhanced image obtained by the contrast improvement process with the input image. The combined image is then output to a desired device such as a printer by an image output unit.

  • Patent number: 7881555
    Abstract: A system and method to reduce bright burn in images, such as x-ray images. The reduction of bright burn may be accomplished by processing a received raw image to obtain a grey-value histogram. The raw image may be divided into a plurality of regions of interest, and an average signal of each region of interest is calculated. Regions of interest are identified as bright burn candidates based on a predetermined function of the average signal of each region of interest and the grey-value histogram of the entire raw image. The regions of interest may be analyzed for local connectivity to estimate bright burn areas. An image with reduced bright burn is generated by either automatically adjusting a physical wedge filter position based on the bright burn areas, or by adaptively reducing a signal level of the bright burn areas.

  • Patent number: 7683912
    Abstract: An image display apparatus in which image signals of a plurality of primary colors are transformed by an image processing section into color space that includes lightness and chromaticity. When the chromaticity (color vividness) in this color space is being corrected, the correction method is changed in accordance with the optical modulation state of the display apparatus. If optical modulation is performed, then correction is made to lower the chromaticity, while correction is made to raise the chromaticity when there is no optical modulation.

  • Patent number: 7653518
    Abstract: A method for generating matched contour profiles includes the steps of trimming or extending an input wire to create a modified input wire and slicing a solid part in the plane of the modified input wire to create an intersection wire. The method also includes the steps of imprinting the modified input wire and the intersection wire on a disk to create one or more faces of interest, determining which faces of interest constitute matched contour faces, and extracting edges of an identified matched contour face to create a closed wire. Matched contour profiles enable solid modeling programs to generate solid models that are less prone to failure because the matched contour profile automatically adapts to changes in the shape of the solid model.

  • Patent number: RE41631
    Abstract: Gamma correction or other power Power functions and other self-similar functions are generated for correcting the light intensity for digital pixels implemented in hardware. Two levels of mapping of segments are preformed to reduce the total number of segments for a given precision. The A range of inputs is divided into successively smaller segments. Two levels of mapping of segments are performed. Each segment is smaller than the next by a factor of 1/a for a first or primary level, or 1/b for a second level of segments. All inputs are mapped of scaled up to the input range of the largest segment in the primary level. Then the largest primary segment is further divided into several second-level segments, and the input is again mapped or scaled into the largest of the second-level segments. Gamma correction The function is performed on the input scaled into the largest second-level segment. A linear approximation within the largest second-level segment is used.
