Abstract: A gamut error false color display uses false coloring on a monochrome image of a video picture being tested. Composite and component gamut error signals are extracted from an input video signal representing the video picture being tested. Such error signals may represent gamut error states corresponding to near out-of-gamut, out-of-gamut high, near out-of-gamut low, out-of-gamut low, etc. A false color display generator has the gamut error signals and a luminance component of the input video signal as inputs and outputs the gamut false color display as the monochrome image with different colors for those pixels in the monochrome image that correspond to the gamut error signals when a gamut error is indicated. Each display component may be tested for gamut errors as well as the video picture as a whole (component or composite). Also either fixed or variable persistence may be used to identify gamut errors over several video pictures in the input video signal.

Abstract: A method and system for image chroma suppression of an image sensor system. Chroma suppression is performed to reduce the false color phenomena. The amount of chroma suppression is performed based on the strength of spatial frequency for a current processing pixel measured during edge detection. In determining the strength of spatial frequency of the current processing pixel, only a small number of green pixel values are needed, regardless of whether or not the current processing pixel is a green pixel within the Bayer pattern. As such, line buffers from the color interpolation module of an image sensor system can also be used for the purpose of chroma suppression.

Abstract: A method beginning at (10) is provided for creating high-fidelity visible coloring from infrared images of a scene under surveillance. The infrared images captured at (12) are analyzed at (14) to determine if an object, such as a face, is identifiable within the image. If an object is identifiable at (16) the object features are compared to a plurality of stored object features at (20). If there is a match at (22), the color characteristics of the object are obtained at (24) and the object is colored at (26) based on the stored database feature information. If there is no match at (22) or identifiable object at (16) and object color cannot be identified at (23), the image is analyzed at (28) to determine if a pattern, such as clothing, is identifiable within the image. If a pattern is identifiable at (30), the color characteristics of the pattern are obtained at (34) and the pattern is colored at (36) according to infrared reflectance characterization in conjunction with the stored pattern information.

The specified grayscale value or range of grayscale values for which pixels are displayed in each successive displayed version of the image is incremented or decremented from the specified grayscale value or range of grayscale values for which pixels are displayed in the immediately previous displayed version of the image by a specified grayscale value increment or decrement.

Abstract: The present invention provides a registration correction method for image processing, by which location deviations among images with different behaviors such as visible ray images and invisible ray images can be corrected. According to this method, one of a visible ray image and an invisible ray image is designated as a reference image, and the other as an object image. A reference window is set within the reference image, and an object window of the same size as the reference window is set within the object image. While the object window is shifted by the pixel within the object image, the differential values of the brightness in the x-axis and y-axis directions of each pixel in the reference window and the object window are obtained. The object point where the total of the squares or the absolute values of the differences between the differential values of the reference window and the object window becomes smallest is set as the point corresponding to the reference point of the reference window.

The minimum value extraction unit extracts and outputs the minimum value of each field of an image signal.

Abstract: With the new plasma display panel technology new kinds of artefacts can occur in video pictures. These artefacts are commonly described as “dynamic false contour effect”, since they correspond to disturbances of gray levels and colors in the form of an apparition of colored edges in the picture when the observation point on the PDP screen moves. According to the invention, such an artefact is compensated by analyzing the motion in the pictures, assigning to each block of a picture a corresponding motion vector and performing a re-coding step in which the different sub-fields of a pixel are shifted to distribute the sub-fields of a pixel more closely on the eye trajectory.

Abstract: Digital signals are generated and stored for each pixel of a frame of a preferably high definition video originated material. A computer reads the digital signals and converts them to binary image data by employing a selected look-up-table program to reassign color and black component values for each pixel. The programs applied in the component value reassignments are compiled from, and based on, comparative digital video component results of telecined film stocks' responses to selected color and grey scale gradients as charted against a selected video unit's response to the same charts under a selected number of identical lighting circumstances. The revised digital data is assembled and converted to an analog signal for a secondary modification wherein: A projector unit projects the high definition video frame through a macro lens onto a strip of exposed and processed motion picture or other photographic film of an optional grey scale gradient and thus grain pattern density.
