<p>A temporal recursive filter unit (100,200,300,400) for noise filtering of a series of input images resulting in a series of output images comprises: means (102) for determining a value of a weighing factor, on basis of a difference between a first value of a first pixel of an input image and a second value of a second pixel of a first output image; and an adding (104) unit for calculating a third value of a third pixel of a second output image by adding of a first product of the value of the weighing factor and the first value of the first pixel, to a second product of a complement of the value of the weighing factor and the second value of the second pixel. The value (508) of the weighing factor is higher below a predetermined threshold (506) than above the threshold (506).</p> |
