    摘要: The present invention is a two-step, contour-sensitive deinterlacing technique. The first step of the technique determines for each missing pixel of an interlaced frame of image pixels whether the absolute difference between the pixels above and below the missing pixel is greater than a preselected threshold value. If it is decided that the missing pixel lies at a low-vertical frequency location, its value is estimated via vertical interpolation. Otherwise, the second step is carried out. The goal of the second step is to determine whether or not there is a well-defined contour passing through the missing pixel, and to determine its direction if there is one. In the presence of a well-defined contour, the missing pixel is obtained by averaging the intensity values along the direction of the contour in the field lines immediately above and below the missing field line. Otherwise the process effectively falls back to vertical interpolation. The presence of a well-defined contour is detected by comparing the summed absolute differences (SAD) of blocks of pixels along a predetermined set of candidate directions, including the vertical direction, and selecting the direction associated with the least SAD. The fall-back to vertical interpolation in the absence of a well-defined contour is implicit due to the weighting of the SAD corresponding to the vertical direction.

    摘要: A hybrid deinterlace mechanism employs motion detection as a precursor to select the value for each missing pixel of a deinterlaced frame, which is generated by using four consecutive fields to produce a motion detection map that is subsequently coupled to a deinterlacer, together with a selected two of the four consecutive fields. These two selected fields and the motion map are sufficient for the deinterlacer to completely characterize the resulting deinterlaced frame. The deinterlacer switches between vertical interpolation and merging based upon motion. Motion is detected by applying a logic OR operation to respective even and odd field binary motion detection signals. In the absence of motion, the pixel values of an odd field and its immediately succeeding even field are merged. On the other hand, if motion is detected, vertical interpolation is carried out for the even field, by a linear combination of immediately adjacent pixels, respectively above and below the pixel of interest.

    摘要: A process and apparatus for generating a deinterlaced digital output image from a plurality of sequential interlaced image fields processes selected ones (a pair of immediately successive fields of the same polarity) of the plurality of sequential interlaced image fields, so as to produce a global motion vector estimate of global translational motion between the selected image fields. An accuracy map representative of accuracy of motion compensation is then generated in accordance with the global motion vector estimate. An adaptive deinterlacer selectively deinterlaces one of the image fields in accordance with the accuracy map. The selectively deinterlaced image field is subjected to postprocessing in order to remove judder artifacts that may be present in the deinterlaced image field as a result of a misclassification of the global motion vector estimate as being accurate in one or more image regions of the deinterlaced image field.

    摘要: A robust system, adaptive to motion estimation accuracy, for creating a high resolution image from a sequence of lower resolution motion images produces a mapping transformation for each low resolution image to map pixels in each low resolution image into locations in the high resolution image. A combined point spread function (PSF) is computed for each pixel in each lower resolution image employing the mapping transformations provided that they describe accurate motion vectors. The high resolution image is generated from the lower resolution images employing the combined PSF's by projection onto convex sets (POCS), where sets and associated projections are defined only for those pixels whose motion vector estimates are accurate.

    摘要: A hybrid deinterlace mechanism employs motion detection as a precursor to select the value for each missing pixel of a deinterlaced frame. If the missing pixel is found to belong to a steady or non-motion portion of the image, then its value is replaced by the corresponding value in the adjacent field (i.e., merging is performed). Otherwise, (where image motion is present) spatial interpolation, preferably edge-adaptive interpolation, is employed to determine the value of the missing pixel.

    摘要: A display device includes power management by including a first input suitable to receive electrical power from an outlet for providing power for the operation of the display device. The display device includes a second input, separate from the first input, suitable to receive electrical power from an external battery source for providing power for the operation of the display device. The display device includes an internal battery source enclosed within the display device suitable for providing power for the operation of the display device. A source select is enclosed within the display device that selects power from at least one of the first input, the second input, and the internal battery for providing power for the operation of the display device. A processor receives video content from a video source and selectively modifies a backlight of the display device based upon the power source selected by the source select in such a manner as to reduce the power consumption of the display device. The processor may additionally change the media playback behavior to decode and playback only some of the video frames to reduce the power consumption of decoder and display device.

    摘要: A system includes additional information together with a video stream, where the additional information is related to at least one of the frames. Preferably the additional information is related to an object within the frame. A receiver receives the video and additional information and decodes the video in the same manner independently of whether the additional information is provided. The additional information is selectively presented to a viewer at approximately the time of receiving the frames. The system may also present information to a viewer from a unitary file containing an image and additional information associated with the image. A selection mechanism permits the selection of objects in the image for which the additional information is related thereto. A presentation mechanism provides the additional information to a viewer in response to selecting the object.
