Filed:

May 30, 2002

Appl. No.:

10/159805

Inventors:

Siu-Leong Yu - San Jose CA, US
Yi Liu - San Ramon CA, US

Assignee:

ESS Technology, Inc. - Fremont CA

International Classification:

H04N 7/12
H04B 1/66

US Classification:

37524012

Abstract:

To detect color motion artifacts in a video frame, a motion-compensated color-distance value is compared against a threshold value. If the motion-compensated color-distance value is greater than or equal to the threshold value, color-motion artifacts are detected. The motion-compensated color-distance value is a sum of absolute values of the differences between corresponding pixel values of the video frame and a reference frame. To detect color motion artifacts in a video frame, in another embodiment, luminance and chrominance components of the intra-frame activity levels are compared against luminance and chrominance components of the inter-frame activity levels. If any of the components of the inter-frame activity levels is greater than the corresponding components of the intra-frame activity levels, color-motion artifacts are detected. To reduce color-motion artifacts, either a smaller quantization scale or intra-frame encoding is used to encode the data.

International Classification:

H04N 7/12

US Classification:

37524012

Abstract:

A portion of the number of bits initially allocated for encoding some of the frames of a group of pictures (GOP) is accumulated in a bit bank and is subsequently used to encode other frames that may require a larger number of bits to encode than those initially allocated for these frames. Furthermore, when a scene change P frame is detected in a first GOP, a second GOP is formed. The second GOP includes the scene change P frame as well as the remaining unencoded frames of the original GOP. The P frame of the first GOP is changed to an I frame in the second GOP. Furthermore, the frame to be displayed after the I frame of the second GOP is also changed to a duplicate of the I frame of the second GOP.

International Classification:

H04B 1/66

US Classification:

37524012

Abstract:

A memory control apparatus for block-matching motion estimation and an associated search pattern for processing video sequence in real-time are described in this disclosure. The motion estimation subsystem utilizes a set of memory banks to store a section of the reference picture used for computing the differences between an underlying block and a spatially shifted reference block. The memory control apparatus derives the memory addresses for storing the reference picture region in the memory banks in such a way that a row or a column of data from the reference block can be accessed in parallel without wait. The row- or column-data are then made available to the parallel computation unit for computing the block difference in a single processing cycle. An associated spiral search pattern that covers the whole search region is also described that minimizes the required data access and consequently saves power consumption. Combined with a search-stop criterion, the search pattern will result in early search termination during the block-matching motion estimation process and consequently conserves more power.

International Classification:

H04N 7/01

US Classification:

348441, 348452, 348459

Abstract:

A method for interpolating a pixel value of a pixel located at an OSD object during frame rate conversion includes determining current forward motion vectors between a first previous video frame and a current video frame, and at least one other set of forward motion vectors between two temporally consecutive previous video frames. The method also includes determining that a block adjoining a target block includes pixels depicting at least a portion of an OSD object. The method also includes determining that a position of the adjoining block relative to the target block coincides with a direction of a current forward motion vector associated with the target block, setting a magnitude of the current forward motion vector to zero (0), and calculating a pixel value of a pixel in the target block in the interpolated video frame based on the current forward motion vector associated with the target block.
