Abstract: A system and method for distributing candidate motion vectors divides a picture frame (110) into a plurality of segments (120), where each segment (120) includes a plurality of pixel blocks (130). The local motion complexity of each segment may then be measured by determining a Sum-of-Absolute Differences (SAD) between pixel blocks (130) of the frame (110a) and pixel blocks (130)of an adacent frame (110b) and summing the SAD values for the pixel blocks (130) within each segment (120). The maximum, minimum and average SAD value for the segments may be used to define a distribution function that distributes candidate vectors to conform with a desired maximum, minimum and average number of candidate vectors per block. This distribution function is then used to determine the number of candidate vectors to assign to pixel blocks (130) based on the measured SAD value of the associated segment (120).

Abstract: In an image processor, a color format converter (CFC) converts a pixel (Pi,j), which is expressed in an RGB color space, into a converted pixel (PCi,j), which is expressed in an YUV color space. A color shift vector generator (CSO, SVC) generates a color shift vector (SVi,j), which is expressed in the YUV color space, on the basis of the converted pixel (PCi,j). An inverse color format converter (ICFC) converts the color shift vector (SVi,j) into a color enhancement vector (EVi,j), which is expressed in the RGB color space. An adder (ADD) adds the color enhancement vector (EVi,j) to the pixel (Pi,j) so as to obtain a color enhanced pixel (PEi,j).

Abstract: In a global motion estimation, profiles (Prof1, Prof2, ProO, Prof4) are determined of frames (FR1, FR2, FR3, FR4) of an input video signal. Each profile comprises a value, for each pixel in a first direction of the frame, which is obtained by combining pixels in a second direction of the frame. The profiles are updated (Upd Prof) with a first shift (?x?12, ?x?2, ?x?34) to obtain updated profiles (Prof1?, Prof2?, Pro3?), and the updated profiles are matched (S/M) to obtain a secondary shift (?x?12, ?x?23). Preferably, the first shift is a zero shift. The updating may be effected by shifting one of the profiles over the first shift to obtain a shifted profile, and subtracting another one of the profiles from the shifted profile. If the second direction is the vertical direction, the profile may comprise a vertically combined (e.g. averaged) pixel value for each pixel in the horizontal direction.
