摘要： A control signal (k_lum) derived from the luminance component (Y) of a video signal is used to adaptively control a temporal noise reduction filter (10) according to the level of motion in a video image. To compress the control signal for storage in a memory (30), the control signal is averaged over each 2×2 pixel area, and then a non-linear compression function is applied. The non-linear compression function preferably selects quantization values of the control signal which correspond to a perceptually substantially linear response in the noise reduction factor (NRF) of the noise filter (10).

摘要： An apparatus and method for facilitating a subsequent choice of a motion vector from a plurality of candidate motion vectors in a motion estimation method, include receiving video image data from first, second and third consecutive groups (10, 20, 30) of image data. A first image part (12) of the first group of image data (10), a second image part (22) of the second group of image data (20), and a third image part (32) of the third group of image data (30) are identified, wherein the positions of the three image parts (12, 22, 32) correspond to a motion trajectory that is indicated by a candidate motion vector. A first error measure is then calculated by testing for differences between the first image part (12) and the third image part (32) and quantified as a first error measure. A second error measure is calculated by testing for differences between either the first image part (12) and the second image part (22) or the second image part and the third image part and quantified as a second error measure. An output error measure is then quantified, wherein the output error measure is derived from either the first or the second or a combination of both error measures.

摘要： The image processor (101) for motion compensated image processing comprises a motion compensation unit (106) for calculating an output image based on a particular motion vector field and based on a first input image and a second input image. The particular motion vector field can be calculated by a motion estimator (104) which is part of the image processor (101) or by an external unit (108). The image processor (101) is designed to select from which source, i.e. the motion estimator (104) or the external unit (108), the particular motion vector field is taken to calculate the output image. The external source is designed to calculate the particular motion vector field based on a motion vector field which was provided by the motion estimator (104) of the image processor (101).
